Description

HANDLE OF LIPOSUCTION

Technical Field

[1] The present invention relates a handle of liposuction, and in particular to a handle of liposuction which is able to more easily cutting a lump of fat by using a cutting blade used for cutting a lump of fat, and which is able to faster and more reliably sucking the cut or decomposed fat by concurrently supplying a fat decomposition liquid and water during a fat cutting and suction process. Background Art

[2] Generally, a fat person or a low weight person tries to control the eating amount of foods so as to keep a proper weight. This food control is called a diet in a medical expression. In recent years, as a social trend changes a lot on the diet, various kinds of diets are developed and currently used.

[3] In recent years, almost people might not suffer from eating as an economy is developed, but their physical behavior decreases more and more due to automation in a production system, so it is not easy to burn all calories obtained daily with a simple life activity.

[4] So, it is reported that a lot of people suffer from an over weight, namely, obesity, and they are trying to maintain proper weights. As a proper method for above trials, there are a dietetic therapy for controlling the amount of foods, and an exercise therapy for enhancing a body physical condition through exercise and making a healthy body.

[5] However, the above exercise and dietetic therapies are subject to decreasing only the sizes of fat cells, so the thickness of fat layers might increase. So, a suction lipectomy is widely performed so as to suck and remove an over developed fat layer. Since the suction lipectomy is directed to decreasing the number of fat cells, it is advantageous that the problems not resolved so far by an exercise or dietetic therapy can be easily resolved.

[6] The suction lipectomy is a method for physically removing over accumulated fat cells. In the suction lipectomy, a tube shaped cannula is inserted into a fat layer, and the fat is sucked to the outside through the cannula. The cannula inserted into the fat layer is operated to separate, destroy and suck fat while moving in forward and backward directions. Such a liposuction has been studied more intensively and developed so as to more effectively suck fat.

[7] The conventional liposuction sucks fat in such a manner that a fat decomposition liquid(Tumescent fluid, anesthesia, bleeding stopping function included) is injected, and then the cannula is inserted after a certain time, so the decomposed and cut fat is sucked and removed to the outside. However, in this case, there is a certain time difference between the injection of the fat decomposition liquid and the suction of the decomposed and cut fat, so the efficiency of the fat suction disadvantageously decreases.

[8] In addition, since the conventional cannula is made in a straight shape, a hard work is needed for cutting fat layers. When an operator inserts a cannula into a fat layer and moves the same in the forward and backward directions with the helps of the vibrations by means of a motor, the operator might hurt another normal tissue. Disclosure of Invention Technical Problem

[9] Accordingly, it is an object of the present invention to provide a handle of liposuction which does not need an additional operation and device when cutting a lump of fat while achieving an efficient fat cutting and suction operation. Technical Solution

[10] To achieve the above objects, in a handle of liposuction used in a fat suction apparatus, there is provided a handle of liposuction comprising a body which is shaped to be easily held by a user; a first cannula which has a rear end inserted into the body or passing through the same, and a front end longitudinally extended toward a front side of the body and has a first suction port provided at a front end of the same for sucking fat; and a cutting blade which is protruded from an outer side of the first suction port for cutting a lump of fat to be sucked.

[11] To achieve the above objects, in a handle of liposuction used in a fat suction apparatus, there is provided a handle of liposuction comprising a body which is shaped to be easily held by a user; a first cannula which has a rear end inserted into the body or passing through the same, a front end longitudinally extended toward a front side of the body, and has an engaging part provided in a front side with its diameter being decreased, and has a first suction port provided at a front end of the same for sucking fat; a second cannula which is formed in a front side of the body while surrounding the first cannula and has a second suction port at a portion corresponding to the first suction port in a front side; and a cutting blade which is slidably engaged in the engaging part in forward and backward directions and is formed of an elastic material and is outwardly protruded to the outside of the second suction port when being compressed.

Advantageous Effects

[12] The present invention has the following advantages.

[13] First, it is possible to effectively cut fat and fast and easily operate with the helps of an operation of a first cannula and a rotation of a cutting blade. [14] Second, a protruded height of a cutting blade can be adjusted, so it is possible to make a cutting blade to protrude at a certain height depending on the portion that a first cannula is inserted.

[15] Third, a fat decomposition liquid or water might be supplied to a fat removal portion of a human body through an adjusting tube which adjusts the protruded height of a cutting blade for thereby achieving a simple structure, and cutting and suction operations of fat are easy.

[16] Fourth, a fat cutting and removing process might be more effectively performed with the helps of a cutting blade as a first cannula engaged with a cutting blade rotates at an eccentric angle. Brief Description of Drawings

[22] Figure 1 is a perspective view illustrating a handle of liposuction according to an embodiment of the present invention.

[23] The handle 1 of liposuction according to a preferred embodiment of the present invention comprises a body 20 which can be easily held by hands, a first cannula 20 which has a rear end being inserted into the body 10 or passes through the same, a front end being is longitudinally extended toward a front side of the body 10, and a first suction port 21 formed in its front side for sucking cut fat, and a cutting blade 40 which is protruded from an outer side of the first suction port 21 for cutting fat sucked.

[24] Here, the body 10 corresponds to a portion which is held by hands when a user uses the handle of liposuction according to the present invention. The body 10 is equipped with a certain driving apparatus for driving the first cannula 20. Here, the first cannula 20 rotates in all directions like a conventional cannula. The first cannula 20 has a certain construction like a cannula generally used in the liposuction apparatus. Here, it is not easy to effectively remove fat only with a suction force supplied from a cannula. So, a particular operation or construction is needed so as to effectively cut fat to be cut and removed from a corresponding portion using a cannula. The above operation and construction will be described later.

[25] The first cannula 20 might be formed with its part being inserted into the body 10 or as shown in Figure 1 its part might passes through. The first cannula 20 is inserted into a fat portion to be removed, and is equipped with a first suction port 21 provided at a front side of the same for sucking cut fat. The first cannula 20 has a diameter relatively small enough for effectively removing cut fat without hurting a normal part of a human body. The size of the first suction port 21, which is formed in the first cannula 20 and functions as a suction passage of the fat, is substantially small enough as well. It is preferred that the first suction port 21 is longitudinally formed in the forward and backward directions depending on the construction of the first cannula 20.

[26] The first suction port 21 is preferably provided in multiple numbers along a circumferential surface of the first cannula 20, and preferably three first suction ports 21 are provided depending on their sizes and functions.

[27] A suction force generated from a suction force generator(not shown) is transferred into the interior of the first cannula 20, and pieces of cut fat positioned near the first suction port 21 among a lot of fat pieces cut by means of the cutting blade 40 are sucked into the interior by means of the suction force from the first cannula 20. The pieces of fat moved toward the backside of the first cannula 20 are discharged through a discharge passage(not shown), and the pieces of fat continue to be sucked and discharged.

[28] The cutting blade 40 is a means for cutting a lump of fat into a predetermined size and shape good enough for a suction and discharge through the first cannula 20 and is formed in the first suction port 21.

[29] It is preferred that the cutting blade 40 is formed in the same direction as the cutting direction when the first cannula 20 is driven by means of rotations. The cutting blade 40 is designed to operate properly since the first cannula 20 formed in a thin tube shape rotates about a longitudinal axis and reciprocates in left and right directions. The cutting blade 40 might be formed in an arc shape protruded in a direction perpendicular to a longitudinal direction of the first cannula 20. Here, it might be formed in various shapes such as a triangle shape or a rectangular shape for properly cutting a lump of fat.

[30] Figure 2 and Figure 3 are cross sectional views illustrating a handle of liposuction according to another embodiment of the present invention.

[31] The handle of liposuction according to a preferred embodiment of the present invention comprises a body 10 which is shaped to be easily held by a user; a first cannula 20 which has a rear end inserted into the body 10 or passing through the same, a front end longitudinally extended toward a front side of the body 10, and has an engaging part 22 provided in a front side with its diameter being decreased, and has a first suction port 21 provided at a front end of the same for sucking fat; a second cannula 30 which is formed in a front side of the body 10 while surrounding the first cannula 20 and has a second suction port 31 at a portion corresponding to the first suction port 31 in a front side; and a cutting blade which is slidably engaged in the engaging part 22 in forward and backward directions and is formed of an elastic material and is outwardly protruded to the outside of the second suction port when being compressed.

[32] The engaging part 22 is formed in a front side of the first cannula 20, and the cutting blade 40 is engaged to the engaging part 22. The cutting blade 40 is slidably engaged to the engaging part 22 in the forward and backward directions, not being fixed to the engaging part 22. The engaging part 22 is integral to the first cannula 20 with its diameter being gradually decreased. The first suction port 21 is longitudinally formed in the engaging part 22 in the forward and backward directions.

[33] It is preferred that the first suction port 21 is divided in the engaging part 22 in a longitudinal direction. Since the engaging part 22 is formed of a tube thinner than the first cannula 20, when one first suction port 21 is longitudinally formed in the engaging part 22, the portions except for the first suction port 21 might collapse on the engaging part 22 due to a concentrating load. So, the first suction port 21 is divided so as to prevent the above collapse.

[34] The second cannula 30 is engaged surrounding a front side of the first cannula 20 and is slidable in the forward and backward directions with respect to the first cannula 20. When the second cannula 30 slides, the cutting blade 40 is pressed and compressed. The second cannula 30 slides as much as the cutting blade 40 can be compressed and outwardly protruded from an outer side of the second suction port 31.

[35] In the second cannula 30, the second suction port 31 is formed in a portion corresponding to the first suction port 21. The second suction port 31 is larger than the first suction port 21 for not preventing suction of fat. The second suction port 31 is provided in multiple numbers along a circumference surface of the second cannula like the first suction port 21.

[36] The cutting blade 40 is not fixedly engaged to the first cannula 20, but slides on the engaging part 22 formed in a front side of the second cannula 30.

[37] Since the cutting blade 40 is exposed to the outside of the second cannula 20, the protruded cutting blade 40 might collide with other objects, which leads to damage. In the present invention, the cutting blade 40 is stored in the interior of the second cannula 30, so that it cannot be exposed to the outside. It is exposed to the outside when in use.

[38] The cutting blade 40 is formed in a rod shape and is preferably made of an elastic material. The sides of the cutting blade 40 are made sharp for effectively cutting a lump of fat. When the second cannula 30 slides in one side direction with respect to the first cannula 20 in a state that the cutting blade 40 is not exposed to the outside of the second cannula 30, one end of the cutting blade 40 stays at a fixed position on the engaging part 22, and the other end of the same slides, so the cutting blade 40 is compressed. As shown in Figure 2 and Figure 3, one end or both ends of the cutting blade 40 are engaged with a support ring 70, respectively. Since the support ring 70 is inserted into the engaging part 22 with one end or both ends of the cutting blade 40 being engaged, the second cannula 30 slides in one side direction with respect to the first cannula 20, and the cutting blade 40 is protruded outwardly.

[39] The protruding operation of the cutting blade 40 will be described with reference to

Figure 2 and Figure 3.

[40] The length of the cutting blade 40 is slightly longer than that of the engaging part 22.

The rear end of the cutting blade 40 is engaged to a shoulder of the rear end of the engaging part 22, and the front end of the cutting blade 40 becomes a free end. When the second cannula 30 moves backward, the inner side of the front end of the second cannula 30 presses a front end of the cutting blade 40, and the cutting blade 40 is protruded from an outer side of the second suction port 31 while receiving a compressing force.

[41] Figure 4 and Figure 5 are cross sectional views illustrating a handle of liposuction according to further another embodiment of the present invention.

[42] The handle 1 of liposuction according to a preferred embodiment of the present invention further comprises an adjusting tube 50, with its front side being engaged to a rear end of the second cannula 30, and with its rear side being engaged to a rim of the first cannula 20, for thereby sliding the second cannula 30 in the forward and backward directions of the first cannula 20.

[43] The cutting blade 40 is protruded in an arc shape upon receiving a compression force in one side direction by means of a sliding operation of the second cannula 30.

[44] It is preferred that the cutting blade 40 might be inserted into the interior of the second cannula 30 or might be substantially protruded, and more preferably it might be protruded at a preferred height depending on the characteristics of a human body who will have liposuction. The adjusting tube 50 allows the cutting blade 40 to have a certain height.

[45] The adjusting tube 50 is engaged to a rear end of the second cannula 30 and is engaged to a rim of the first cannula 20, respectively, for thereby being movable in the forward and backward directions of the first cannula 20.

[46] The support ring 70 is engaged to one side or both sides of the cutting blade, and the support ring 70 is slidably engaged to a rim of the engaging part 22. [47] Here, the adjusting tube 50 is movable in the forward and backward directions of the first cannula. At this time, the second cannula 30 slides in the forward and backward directions in the first cannula 20. The adjusting tube 50 is thread-engaged to a rim of the first cannula 20, with the tops and bottoms of threads being formed at their corresponding positions.

[48] One end of the cutting blade 40 is supported by means of the first cannula 20 on the engaging part 22, and the other end of the same is pressed depending on a sliding operation of the second cannula 30, so the cutting blade 40 is compressed.

[49] The front end of the cutting blade 40 is supported by means of the first cannula 20, and the rear end of the same slides. As shown in Figure 3, the rear end of the cutting blade 40 might be supported by means of the first cannula 20, and the front end of the same might slide by means of the second cannula 30.

[50] In the former case, when the adjusting tube 50 is moved toward a front side of the first cannula 20, the cutting blade 40 forwardly pushed and compressed by means of the second cannula 30 is protruded from an outer side of the second suction port 31, and in the later case, when the adjusting tube 50 is moved toward a rear side of the first cannula 20, the cutting blade 40 pulled backwardly and compressed by means of the second cannula 30 is exposed from an outer side of the second suction port 31.

[51] The adjusting tube 50 stops at a properly protruded height of the cutting blade 40, and the movement of the adjusting tube 50 is stopped by means of a fixing key 60. Here, the fixing key 60 is a means for stopping the movement of the adjusting tube 50 and is engaged to a rim of the first cannula 20. The fixing key 60 might be thread- engaged with the adjusting tube 50. A male thread might be formed in the fixing key 60. A female thread might be formed instead.

[52] Figure 6 is a cross sectional view illustrating a handle of liposuction according to further another embodiment of the present invention.

[53] In the handle 1 of liposuction according to another embodiment of the present invention, the adjusting tube 50 might be equipped with a fluid inlet port 51 in its one side, and the fluid inputted through the fluid inlet port 51 is supplied between the first and second cannula 20 and 30.

[54] Fat decomposition liquid or water might be inputted into the fluid inlet port 51 or a lump of fat to be cut or decomposed might be supplied. The process for supplying fat decomposition liquid to a human body and the process for sucking cut fat might be concurrently performed in the present invention.

[55] The fluid inlet port 51 passes trough part of the adjusting tube 50 and reaches an inner surface of the adjusting tube 50. The fluid inlet port 51 is formed from an inner surface of the adjusting tube 50 to a backside of the rear end of the second cannula 30 for thereby preventing the flow of the fluid from being stopped by the second cannula 30.

[56] A certain gap is formed between the inner wall of the second cannula 20 and the outer wall of the first cannula 30 for allowing the fluid to flow. The inputted fluid moves toward the first suction port 21 and reaches the fat to be cut or decomposed.

[57] Figure 7 is a cross sectional view illustrating a handle of liposuction according to further another embodiment of the present invention.

[58] The handle 1 of liposuction according to a preferred embodiment of the present invention comprises a driving motor 11 installed in the interior of the body 10, a main shaft gear 12 driven by means of the driving motor, and an eccentric gear 13 engaged with the main shaft gear 12. The first cannula 20 is engaged with the eccentric gear 13 at an eccentric angle.

[59] The first cannula 20 is not engaged coinciding with the center axis of the eccentric gear 13, but is engaged at a portion slightly spaced from the center axis of the eccentric gear 13. So, when the motor is driven, and the main shaft gear 12 rotates, the eccentric gear 13 engaged with the same rotates, and the first cannula 20 and the second cannula 30 engaged with the first cannula 20 rotate with a rotation radius as much as the eccentric range.

[60] When the first cannula 20 is engaged coinciding with the center axis of the eccentric gear 13, the first cannula 20 simply rotates by means of the motor. In this case, a movable range of the cutting blade 40 might be narrower. However, in the present invention, when the first cannula 20 is engaged with the eccentric gear 13 at an eccentric angle, the movable range of the cutting blade 40 is expanded as much as the eccentric range for thereby more effectively cutting a lump of fat.

[61] In the handle 1 of liposuction according to a preferred embodiment of the present invention, the driving motor 11 repeatedly rotates in a clockwise direction and a counterclockwise direction, respectively.

[62] If the driving motor 11 continues to rotate in one direction, the suction tube T connected with the first cannula 20 might be twisted, which leads to stopping operation. So, the driving motor 11 is designed to repeatedly rotate in a clockwise direction or a counterclockwise direction while preventing the suction tube T from being twisted. At this time, the driving motor 11 is repeatedly driven at a rotation angle of 120°.

[63] In the handle 1 of liposuction according to a preferred embodiment of the present invention, the cutting blade 40 is provided in multiple numbers.

[64] In the present invention, the cutting blade 40 might be provided in multiple numbers depending on its purpose of use. The protruded heights of the cutting blades 40 might be different for thereby cutting more fat lumps, so it is possible to faster and more effectively cut and remove a lump of fat. [65] As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims. Industrial Applicability

[66] According to the present invention, it is possible to effectively cut fat and fast and easily operate with the helps of an operation of a first cannula and a rotation of a cutting blade.
