Abstract

The utility model relates to a minimally invasive bone grafting device, which can effectively solve the problems of severe trauma and easily caused complication during the bone grafting process. The technical scheme for solving the problems is as follows: the minimally invasive bone grafting device comprises a pipe body and a sclerotin lead-out needle which is mounted in the pipe body and slides vertically, a pipe handle is arranged at the upper end of the pipe body while a mouth piece is mounted at the lower end thereof, and saw-teeth are arranged at the lower end part of the mouth piece. The utility model has simple structure, simple and convenient operation, minimal trauma, low blood loss, less adverse reactions, and earlier off-bed time after the operation, thereby reflecting the innovation in bone grafting operation.

Description

The micro-wound bone taking device

One, technical field

This utility model relates to medical apparatus and instruments, particularly a kind of micro-wound bone taking device.

Two, background technology

In bone surgery, because syntripsis, bone is damaged or bone does not connect etc., often needs bone grafting, in bone-grafting material commonly used, be the best from the osseous tissue of body with patient, therefore, bone grafting operation is used from the body bone maximum.The at present conventional bone method of getting is that method with otch is cut a hole with osteotome behind the exposure skeleton and got, and wound is big, and complication takes place easily, is to get the problem of needing solution in the osseous surgery badly.

Three, utility model content

At above-mentioned situation, for overcoming defective of the prior art, the purpose of this utility model just provides a kind of micro-wound bone taking device, effectively solve the existing problem that complication in the bone patient trauma is taken place greatly, easily of getting, the technical scheme of its solution is, comprise body and sclerotin derivation pin, sclerotin derivation pin is contained in the body and slides up and down, there is the pipe handle body upper end, there is tube head the lower end, there is sawtooth the tube head bottom, and this utility model convenience simple in structure, simple to operation, wound be little, lose blood less, untoward reaction is little, postoperative can be left the bed early, is the innovation of getting on the osseous surgery.

Four, description of drawings

Accompanying drawing is a structural front view of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Provided by accompanying drawing, this utility model includes body and sclerotin is derived pin, and sclerotin derivation pin 1 is contained in the body 3 and slides up and down, and there is pipe handle 2 the body upper end, and there is tube head 5 lower end, and there is sawtooth 6 the tube head bottom.

In order to guarantee result of use, said tube head 5 diameters are littler than body 3 diameters;

Look bone window 4 on the tube head 5 of said body 3 lower ends;

Operating position of the present utility model is to determine to get the bone scope earlier, do the little otch of 1.0-2.0cm with sharp knife then, arrive at by otch and get bone place surface of bone with getting the bone object tube head then, getting the bone object direction when getting bone is about 45 ° of the outer deflection of patient body Y-direction, bone object is got in firmly slow and rotation, breaking through cortical bone enters between the inner and outer plates, turn clockwise and get bone object and slowly advance (the darkest can to 5cm), laciniation by tube head 5 is got bone, slowly rotate again and extract and get bone object, derive pin 1 by sclerotin and will get the sclerotin release that cuts in the bone object body 3, getting bone object enters once more by otch and bone hole, change 5 °-10 ° of front and rear angles, desirable bone 2～3 times is generally got the bone amount at 3cm ³When need bone amount is big; but proper extension skin incision; get bone or to STH in bone surface 2 places perforate; get and after bone is finished otch is sewed up, with aseptic dressing compressing 3-5 minute, adhesive bandage protection otch; finish and get osseous surgery; this utility model convenience simple to operation, wound be little, lose blood less, untoward reaction is little, postoperative can be left the bed early, is the innovation of getting on the osseous surgery, and remarkable economical and social benefit are arranged.
