Abstract
Disclosed in the invention is a puncture guiding device capable of tearing and removing a sheath. The puncture guiding device comprises a casing sheath and a pin embedded into the casing sheath; and the casing sheath and the pin are in integrated modes. The guiding device is characterized in that the two ends of the casing sheath are open; the rear end of the sheath is expanded and is formed by two horn-shaped sheath bodies; grooves are formed in two symmetric sides of a rod body along the length direction; and tearing openings are formed in the grooves. A pair of mutually-matched buckles is arranged at symmetric positions, where the rod body approaches the positions and the two sheath bodies approach each other mutually, of the sheath bodies. The pointed end of the pin is in a shape of a solid cone; and the rear end of the pin is an expanding body matching the sheath bodies of the casing sheath. According to the invention, the structure is simple and the cost is low. Because of the change of the casing sheath structure, the puncture guiding device is suitable for various drainage tubes, especially ones with rear parts with expanding connectors; and the casing sheath can be removed from the wound of a patient in a tearing mode and the implementation is easy to carry out, so that little trauma is caused and thus the pain of the patient suffering from sickness can be substantially reduced.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of can the puncture conductor of avulsion sheath.
Background technology
In modern medical service, drainage be mostly by operation in thoracic cavity, bladder, the internal organs place such as abdominal cavity cut osculum, then drainage tube is implanted by incision site, the method is not only complicated, and bring great wound and the torment of certain slight illness to patient, and want the change of illness state of Real Time Observation patient incision site, in order to avoid there is the problem that cross infection etc. is new.Therefore a kind of new medical procedures is also arisen at the historic moment to realize drain---puncture guid needle, it comprises cover sheath, the nook closing member be nested in cover sheath, after completing puncture by nook closing member, inner nook closing member is taken out, leave outer cover sheath, then drainage tube is penetrated in cover sheath and realize implanting drainage tube, finally outer cover sheath is taken out.And in modern medical equipment, the joint that the rear end of most of drainage tube is all expanded with one, monitoring test is carried out for other armarium external, therefore when using aforesaid puncture guid needle, although drainage tube can be implanted the internal organs such as thoracic cavity, bladder, abdominal cavity by puncture guid needle, but because outer cover sheath cannot take out by the joint that expands of drainage tube rear end smoothly, and hence, limit the use of this kind of drainage tube, for medical personnel located brings certain puzzlement.
Therefore need badly and provide a kind of novel puncture guid needle to solve the problems referred to above.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can the puncture conductor of avulsion sheath, the use of various drainage tube can be applicable to.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of can the puncture conductor of avulsion sheath, comprise cover sheath, be nested in the nook closing member overlapped in sheath, entirety is all in shaft-like, overlap sheath both ends open, rear end is expanded, be made up of the sheath body of two lobe flares, in the symmetrical both sides of the body of rod, be provided with groove along its length, groove is provided with tearing port, is provided with a pair buckle of coupling mutually in the sheath body symmetric position close to each other close to the body of rod, two lobe sheath bodies; The tip of nook closing member is solid cone or three rhombohedreons, and rear end is the body that expands matched with the sheath body of cover sheath.
In a preferred embodiment of the present invention, between two lobe sheath bodies, the direction in space is consistent with the direction of body of rod upper groove, divides de-sheath to make sheath body be more prone to.
In a preferred embodiment of the present invention, tearing port comprises several apertures or threaded openings, if aperture, the small aperture then groove being positioned at lever front end is larger than the small aperture being positioned at body of rod rear end, owing to being positioned at the aperture of body of rod rear end near sheath body, and the little and distribution of the small aperture of rear end closely, when the buckle of sheath body is contacted with each other, the body of rod is more prone to be torn.
In a preferred embodiment of the present invention, the body that expands of nook closing member rear end is round table-like, expands the shape of body and the mating shapes of two lobe sheath bodies.
In a preferred embodiment of the present invention, the tip of nook closing member protrudes from the front end of cover sheath, and the tip due to nook closing member is used for piercing through skin, and the length of therefore overlapping sheath is shorter than the length of nook closing member.
In a preferred embodiment of the present invention, buckle divides pin thread and box, both do not contact, if the shape of pin thread is outwardly, then the shape of box caves inward, not easily produce displacement when both are contacted with each other, when pin thread contacts with box, cover sheath can be torn along its groove by both inconsistent power.
In a preferred embodiment of the present invention, be provided with that several are protruding at the inner surface of sheath body cross section, the corresponding position that body contacts with sheath body cross section of expanding at nook closing member is provided with several the second grooves, makes nook closing member and overlaps sheath and coordinate tight and difficult drop-off.
In a preferred embodiment of the present invention, the material of described cover sheath and nook closing member is medical grade PP plastics or medical grade ABS plastic.This material has good biocompatibility, physicochemical property, and easily produces the untoward reaction such as irritated when body fluid and contact tissue.
The invention has the beneficial effects as follows: structure of the present invention is simple, cost is low, this puncture guid needle is made to be applicable to various drainage tube by the change of cover sheath structure, even rear portion is with expanding the drainage tube of interface, and sheath will be overlapped by the form of tearing and take out patient wound, simple, wound is little, and the slight illness significantly reducing patient torments.
