Abstract

The utility model relates to a medical apparatus, in particular to a bone-separating squeezer for mouth cavity alveolar bones. The squeezer comprises a handle and a chiseling head and is characterized in that the chiseling head is connected with the handle through a jacket and a nut and is in a oblate shape; knife edges are arranged on the periphery at the front end of the chiseling head; due to the adoption of the connection mode that the chiseling head can be changed, a plurality of chiseling heads (generally be divided into 5 grades) can be made, serially cleaved, and used for squeezing bone ridges, so that the squeezing width is increased conically and gradually; while cleaving, the squeezer serves the squeezing function and has the advantages of uniform stress, high safety degree and good use effect; the squeezing width of the bone ridges can achieve 3 mm and form the basic condition of implanting various planting bodies (The width of anterior teeth planting bodies is 3.25 to 4.3 mm); and the operation can be finished easily in combination with a complete bone squeezer supplied by a planting body manufacturer.

Description

The bone squeezer of riving

Technical field:

This utility model relates to medical apparatus and instruments, specifically a kind of bone that is used for oral cavity alveolar bone squeezer of riving.

Background technology:

As everyone knows, behind the absence of tooth, the alveolar ridge atrophy, it is more obvious, rapid that its cheek lingual surface absorbs.Therefore form and have certain bone height, the alveolar ridge that buccolingual diameter is narrower, implantation body does not have enough sclerotin when implanting and holds, primary stability is relatively poor, easily cause the plantation failure, the mode that also often adopts bone to transplant clinically, but prolong the repair time of operation, the expense height, and the patient is difficult for accepting, in recent years, bone ridge to 2-5mm thickness has adopted the mode of bone extruding to implant implantation body, the I stage operation is achieved, in the operation, the apparatus that adopts generally is that the front end at handle is provided with round punch, round punch extruding under the narrower condition in bone footpath is easy to generate stress point and concentrates, and hone lamella very easily breaks, the effect of influence operation.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of when riving, and possess squeeze function, puts forth effort evenly the bone that safe coefficient the is high squeezer of riving.

This utility model can reach by following measure:

A kind of bone squeezer of riving comprises handle, cutter head, it is characterized in that the cutter head is connected with handle through chuck, nut, and the cutter head is oblate shape, and the preceding end periphery of cutter head is provided with blade.

This utility model is owing to adopt the connected mode of replaceable cutter head, the cutter head can be made a plurality of (generally being divided into 5 grades), divide the multistage bone ridge that splits one by one, pushes, the thickness of cutter head is thickeied step by step, make the stepped increase of nip width, when riving, possesses squeeze function, put forth effort evenly, safe coefficient is high, result of use good, extruding bone ridge width can reach 3mm, become the hole basic condition (Anterior Implant body width is 3.25-4.3mm) fully that each implantation body implants, again in conjunction with the supporting bone extruding apparatus of producer of implantation body, the easier operation technique of finishing.

The specific embodiment:

Below in conjunction with accompanying drawing this utility model is further described:

As shown in drawings, a kind of bone squeezer of riving, comprise handle 1, cutter 2, cutter 2 is oblate shape, cutter 2 a preceding end periphery are provided with blade, cutter 2 is through chuck 3, nut 4 is connected with handle 1, this utility model is owing to adopt the connected mode of replaceable cutter head, the cutter head can be made a plurality of (generally being divided into 5 grades), divide multistage the splitting and pushing of bone ridge of carrying out one by one, the thickness of cutter head is thickeied step by step as Fig. 9-shown in Figure 11, makes that the width that splits extruding bone ridge is stepped to be increased gradually, this utility model possesses the function of riving in extruding, have and put forth effort evenly, the safe coefficient height, advantages such as result of use is good, its extruding bone ridge width can reach 3mm, becomes the hole basic condition (Anterior Implant body width is 3.25-4.3mm) fully that each implantation body implants, again in conjunction with the supporting bone extruding apparatus of producer of implantation body, the easier operation technique of finishing.

Claims

1, a kind of bone squeezer of riving comprises handle, cutter head, it is characterized in that the cutter head is connected with handle through chuck, nut, and the cutter head is oblate shape, and the preceding end periphery of cutter head is provided with blade.
