Abstract
The invention relates to a medical instrument, in particular to a distractor for repairing skin defect. The distractor comprises two parallel fixing arms, wherein a device capable of adjusting the distance between the two fixing arms is arranged between the two fixing arms; the fixing arms are provided with cylinders and suture needle fixing clamps; the device capable of adjusting the distance between the two fixing arms can be a threaded rod on which a compressed spring is sleeved, and can also be a lead screw. The distractor has the advantages of simple structure, convenience in use, small wounds caused to the skin, strong treatment controllability, no need of cutting skin or skin flaps from normal skin and smaller postoperative scarring.
Description
(1) technical field
The present invention relates to medical instruments field, particularly a kind of Distraction Apparatus of used for reparing skin defect.
(2) background technology
Skin injury is a kind of complication common after limb trauma.Traditional Therapeutic Method is for utilizing Free Skin Graft or transposition of flap repair deficiency, and its shortcoming is to need to sacrifice for district's skin or soft tissue, and cicatrix is larger, and the transposition of flap specification requirement is high.According to " tension force-stress rule (law of tension stress; LTS) ": to biological tissue continue, stable slow drawing-off, can stimulate or activate some histiocytic regeneration and active growth, the similar fetal tissue of its growth pattern, be identical cell division, control the tensile stress of tractive, bone and soft tissue are renewable.The Ilizarov method that is usually used in skin injury stretching treatment connects external fixer by steel wire, the postoperative skin edge that draws gradually for the skin edge in the wound both sides penetrates Kirschner wire.Its shortcoming is that external fixer is huger, carries inconvenience; And need be fixed on skeleton by Kirschner wire or screw, increase wound.
(3) summary of the invention
The present invention, in order to make up the defect of prior art, provides the Distraction Apparatus of the used for reparing skin defect that a kind of volume is little, confession district skin accurately, is not sacrificed in stretching, wound is little.
The present invention is achieved through the following technical solutions:
A kind of Distraction Apparatus of used for reparing skin defect, it is characterized in that: comprise two parallel fixed arms, the two ends of described fixed arm are provided with the device that can change two distances between fixed arm, and described fixed arm is provided with some sewing needle fixation clamps, and on described fixed arm, cover has slidably cylinder.
The described device that changes two distances between fixed arm comprises and is fixed therein a threaded rod on fixed arm, the other end of described threaded rod is furnished with fastening nut after another root fixed arm passes, this fixed arm can move on threaded rod, on described threaded rod, cover has stage clip, the two ends of described stage clip to be separately fixed on two fixed arms.
The described device that changes two distances between fixed arm is a leading screw with rotating handle, and leading screw is through wherein be connected after a fixed arm axle turnablely with another root fixed arm.
Described cylinder is made of the elastomeric material of high temperature high voltage resistant, and all the other all parts adopt medical stainless steel, aluminium alloy or titanium alloy material to make.
The invention has the beneficial effects as follows:
1, do not limit the range of activity in joint, and easy to carry.
2, the present invention is bound on limbs by latex tubing, and limits the distance between Distraction Apparatus and skin by cylinder, and fixing reliable, wound is very little.
3, the flight pitch on leading screw or threaded rod is accurate, according to the distance that needs stretching every day, adjusts precession speed, and the treatment controllability is strong.
The soft tissue of 4, regenerating by stretching covers the skin injury district gradually, need not cut skin or flap from normal skin, and postoperative scar is less.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 be the first embodiment of the present invention main TV structure schematic diagram;
Fig. 2 be the second embodiment of the present invention main TV structure schematic diagram.
In figure, 1 fixed arm, 2 sewing needle fixation clamps, 3 cylinders, 4 threaded rods, 5 fastening nuts, 6 stage clips, 7 leading screws, 8 rotating handles.
(5) specific embodiment
Accompanying drawing is specific embodiments of the invention.Be illustrated in figure 1 the first embodiment, the Distraction Apparatus of this kind of used for reparing skin defect, comprise two parallel fixed arms 1, the two ends of fixed arm 1 are provided with the device that can change two distances between fixed arm, every fixed arm 1 is provided with three sewing needle fixation clamps 2, and for fixing sewing needle, on every fixed arm 1, cover has two slidably cylinders 3, for limiting the distance of skin and Distraction Apparatus, the elastomeric material of cylinder 3 use high temperature high voltage resistants is made.
The device that can change two distances between fixed arm comprises and is fixed therein a threaded rod 4 on fixed arm 1, porose on another root fixed arm 1, the diameter in this hole is greater than the diameter of threaded rod 4, the other end of threaded rod 4 is furnished with fastening nut 5 from this hole passes, this fixed arm 4 can move on threaded rod 4, on threaded rod 4, cover has stage clip 6, the two ends of stage clip 6 to be separately fixed on two fixed arms 1.
Except cylinder 3, all the other all parts adopt and all adopt medical stainless steel, aluminium alloy or titanium alloy material to make, therefore can the complete machine autoclave sterilization.
Figure 2 shows that the second embodiment, and the difference of the first embodiment only is to change the device of two distances between fixed arm, it is a leading screw with rotating handle 87, leading screw 7 is through wherein be connected after a fixed arm 1 axle turnablely with another root fixed arm 1: can open a blind hole in fixed arm 1 inboard, the end of leading screw 7 withstands in blind hole; The end of leading screw 7 can also be hinged on fixed arm 1, can be also other known methods that leading screw 7 axles are turned.
During use, size according to the skin injury area, in the skin injury both sides, each is by several pieces of Kirschner wires penetrate subcutaneous tissue parallel with the skin edge, medical suture needle is thrust to subcutaneous and next-door neighbour's Kirschner wire outside, each piece of sewing needle is fixed on fixed arm 1 by sewing needle fixation clamp 2, with binder or latex tubing etc., fixed arm 1 is tied up on limbs with fixing Distraction Apparatus, the distance of regulating between two fixed arms 1 by tightening fastening nut 5 or rotating handle 8, thereby shorten the distance of the skin edge of both sides, skin injury place, each 0.25mm, every day 3-4 time.
Except the described technical characterictic of description, all the other technical characterictics are those skilled in the art's known technology.
