Abstract
The utility model discloses a multipurpose needle knife, and belongs to the field of medical apparatuses. The multipurpose needle knife comprises a needle knife body, and is characterized in that the multipurpose needle knife further comprises an outer sleeve sleeved on the needle knife body, wherein the head of the outer sleeve is smooth-shaped; and a through hole allowing a knife head of the needle knife body to pass through is formed at the top end of the head of the outer sleeve. The needle knife with the structure has the following three characteristics: firstly, the purpose of adhesion cutting and stripping of the original needle knife is reserved; secondly, when the sleeve of the needle knife is withdrawn, blood vessels and nerves can be prevented from being injured by utilizing the smooth-shaped head of the outer sleeve; and thirdly, drug injection can be conducted by utilizing the sleeve, that is, if local pain or discomfort occurs in the therapeutic process, anesthetics can be locally injected through the sleeve, and after the therapy is completed, dugs for nourishing the nerves or diminishing inflammation can be injected through the sleeve. Therefore, not only is the original sharpness performance of the needle knife maintained, but also passivity performance is added to the needle knife, thereby reducing injuries to the blood vessels and the nerve tissue.
Description
Technical field
This utility model belongs to the medical appliance field, is specifically related to a kind of multipurpose pin cutter.
Background technology
Small needle knife is a kind of medical appliance that has pin and two kinds of functions of cutter concurrently, in clinical, can the tissue of adhesion be peeled off the retardance mediation; Skin and flesh not being cut again, is the good combination of cutter and pin, for pressing the bone aching that causes in treatment because of soft tissue adhesion or cicatrix card; In treatment clinical course; Usually adopt the pin cutter to carry out closure absent-mindedness operative treatment, this operation safety is reliable, the patient suffering is few, and medical expense is low; Do not need complicated medical assistance apparatus and special medical environment, therefore obtained using widely in clinical current.But in therapeutic process; Since adhesion organization or scar tissue often with nerve and blood vessel companion row, use that the pin cutter relaxes in the cutting process inevitably will cut-out or injured nerve and blood vessel, increased patient's wound; And cause therapentic part to infect easily, reduced the curative effect of operation.
Summary of the invention
This utility model technical problem to be solved provides a kind of multipurpose pin cutter, can carry out blunt separation to patient's treatment region, alleviates the wound to patient.
For solving the problems of the technologies described above; The technical scheme of this utility model is: design a kind of multipurpose pin cutter; Comprise pin cutter body; It is characterized in that: also comprise the trocar sheath that is sleeved on the pin cutter body, the head of trocar sheath is slick and sly shape, and the top of trocar sheath head has the through hole that the cutter head of pin cutter body can pass.
Preferably, the tail end of trocar sheath adds handle portion, and handle portion is sleeved on the handle of pin cutter body.
Preferably, trocar sheath is medical plastic tube.
The beneficial effect of this utility model is:
1, since on pin cutter body suit trocar sheath; The head of trocar sheath is slick and sly shape; The top of trocar sheath head has the through hole that the cutter head of pin cutter body can pass, and the pin cutter of this kind structure has following three characteristics: the firstth, and keep original pin cutter and cut the purposes of peeling off adhesion; The second, the pin cutter being regained telescopic the time, utilize the slick and sly shape head of trocar sheath can avoid injured blood vessel and nerve; The 3rd utilizes sleeve pipe can carry out the medicine injection, if local pain or discomfort in therapeutic process, occur, can pass through sleeve pipe local injection anaesthetic, can be through the medicine of sleeve pipe injection trophic nerve or antiinflammatory after treatment finishes.Make the pin cutter both keep original sharp performance like this, increased the passivity performance again, reduced damage blood vessel and nervous tissue.
2, because the tail end of trocar sheath adds handle portion, and handle portion is sleeved on the handle of pin cutter body, person easy to use is telescopic controlling externally, uses more convenient.
3, trocar sheath is medical plastic tube, has kept the hardness of trocar sheath, has increased patient's the adhesion organization or the peeling rate of scar tissue.
Description of drawings
Fig. 1 is user mode 1 sketch map of this utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is user mode 2 sketch maps of this utility model.
Labelling among the figure: 1, pin cutter body; 2, trocar sheath; 3, handle portion; 4, through hole.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail.
Like Fig. 1,2, shown in 3; The suit head is the trocar sheath 2 of slick and sly shape on pin cutter body 1; The top of trocar sheath 2 heads has through hole 4; The cutter head of pin cutter body 1 can pass from through hole 4, and like this, the pin cutter can be in two kinds of duties in use: a kind ofly bony spur etc. is carried out rigid cutting for sharp pin cutter capable of using; Another kind of for the slick and sly head that utilizes trocar sheath 2 carries out the passivity absent-mindedness to adhesion organization etc., reduced damage to adhesion organization's medium vessels and nervous tissue.The tail end of trocar sheath 2 installs handle portion 3 additional, and handle portion 3 is sleeved on the handle of pin cutter body 1, and person easy to use controls trocar sheath 2, uses more convenient.Above-mentioned trocar sheath 2 is selected medical plastic tube for use, has kept the hardness of trocar sheath 2, has increased patient's the adhesion organization or the absent-mindedness speed of scar tissue.
During use, the cutter head of pin cutter body 1 is passed trocar sheath 2, utilize its prick skin to get into the sufferer portion of human body; If need carry out rigid excision, the cutter head of pin cutter body 1 is exposed, from through hole 4 if need the adhesion organization of sufferer portion be relaxed to bony spur etc.; Then twitch pin cutter body 1 and make in its trocar sheath 2 of from through hole 4, withdrawing; After utilizing the slick and sly head of trocar sheath 2 to carry out blunt separation, and then insert moving pin cutter body 1, make the cutter head of pin cutter body 1 expose trocar sheath 2; And in the confined space, carry out loosening therapy, reduced damage to adhesion organization's medium vessels and nervous tissue.
The above; It only is the preferred embodiment of this utility model; Be not to be the restriction of this utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every this utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of this utility model technical scheme according to the technical spirit of this utility model.
