Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of scalable osteotome.
Background technology
In bone surgery, often need to use osteotome, the osteotome using clinically at present generally includes chiseled body and the chisel grip of one, when cutter osseous tissue, by chisel grip end is knocked, make chiseled body end cutting osseous tissue, at slight part, by scalpel, carry out trickle finishing again, operation very bothers like this, waste time and energy, and owing to carrying out osseous tissue when cutting by knocking chisel grip, be difficult to grasp the depth of cut of inner tissue, often there is cutting problem, be unfavorable for patient's recovery, increased patient's misery.In addition,, owing to often using chiseled body cutting osseous tissue, chiseled body easily breaks down, and therefore has to whole osteotome is discarded, causes waste to increase cost.
Utility model content
For above-mentioned deficiency, this utility model provides a kind of adjustable osteotome, can accurately control the degree of depth that osteotome is cut a hole bone in use, and can regulate according to demand, when chiseled body breaks down, only need to change chiseled body in addition, avoids waste.
For realizing technique scheme, a kind of adjustable osteotome of this utility model, comprise chisel grip and be arranged on the chiseled body in chisel grip, described chisel grip comprises handle and the cutter bar being fixedly connected with, described chiseled body comprises cutter piece and is fixed on the chisel edge of cutter piece one end, it is characterized in that: in the middle of described cutter bar one end, have a cavity, cutter bar has the opening of strip at empty cavity position place, and there is graduation mark in the edge of opening; Described chiseled body has a fixed part away from one end of chisel edge, described fixed part matches with the cavity of cutter bar one end, described fixed part has a screwed hole on surface, one screw matching with screwed hole is installed on described screwed hole, the diameter of bolt of described screw is less than the width of cutter bar surface opening, and the diameter of nut is greater than A/F.
Described cavity and the fixed part shape of mating with it can be cylindrical, cuboids, so that the installation of chiseled body and chisel grip.
Described handle adopts surface to have the taper type structure of some anti-skidding stripeds or salient point, can make medical worker better hold with a firm grip in use, to prevent osteotome landing.
The nut of described screw is hexagon prism structure or shaggy column structure, so that the easier rotary screw of medical worker regulates the position of fixed part in cavity, thereby regulates the cutter bone degree of depth of cutter piece.
During use, the fixed part of chiseled body is stretched in the cavity of cutter bar one end, rotate chiseled body, make the opening on the screwed hole aligned with cavities surface on fixed part surface, then screw is screwed on, screw compresses with cutter bar surface.By recognizing in advance the degree of depth of the required cutter bone of patient, then unscrew screw, fixed part can be moved in cavity, and according to the graduation mark at edge of opening place, can determine the cutter bone degree of depth of chiseled body, screwing screw, makes it and cuts a hole fixedly chiseled body of bar surface compression again.If when the chisel edge of chiseled body causes sharpness inadequate because access times are too much, screw can be screwed out to fixed part and fixed part is taken out from cavity, changing chiseled body.
By the fixed part of chiseled body being extend in the cavity of cutter bar one end, rotate chiseled body, make the opening on the screwed hole aligned with cavities surface on fixed part surface, then screw is screwed on.After recognizing in advance the degree of depth of the required cutter bone of patient, rotary screw, fixed part can be moved in cavity, when reaching suitable position, screwing screw, makes to cut a hole bar and chiseled body is fixed, and can accurately control the depth that patient cuts a hole bone, reduced and needed scalpel to carry out again the process of trickle operation in the past, improved medical worker's work efficiency.In addition, when the chisel edge of chiseled body, because access times while too much causing sharpness inadequate, can screw out screw fixed part and fixed part is taken out from cavity, change chiseled body, not only reduced to waste reducing costs but also having reduced the pollution of waste products to environment.
