Description

A kind of multipurpose pin cutter

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.

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 thetrocar sheath 2 of slick and sly shape on pin cutter body 1; The top oftrocar sheath 2 heads has throughhole 4; The cutter head of pin cutter body 1 can pass from throughhole 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 utilizestrocar 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 oftrocar sheath 2installs handle portion 3 additional, andhandle portion 3 is sleeved on the handle of pin cutter body 1, and person easy to use controls trocarsheath 2, uses more convenient.Above-mentionedtrocar sheath 2 is selected medical plastic tube for use, has kept the hardness oftrocar 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 trocarsheath 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 throughhole 4 if need the adhesion organization of sufferer portion be relaxed to bony spur etc.; Then twitch pin cutter body 1 and make in itstrocar sheath 2 of from throughhole 4, withdrawing; After utilizing the slick and sly head of trocarsheath 2 to carry out blunt separation, and then insert moving pin cutter body 1, make the cutter head of pin cutter body 1 exposetrocar 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.
