Abstract

The utility model discloses an extruded type spinal vertebral body osteotome. The extruded type spinal vertebral body osteotome comprises a striking vertical handle and an osteotome rod which is fixedly connected with the striking vertical handle, wherein the tail end of the osteotome rod is also fixedly connected with an arc bit. The extruded type spinal vertebral body osteotome disclosed by the utility model has the advantages as follows: on the basis of osteotomy of a spinal vertebral body, vertebral spongy bone can be extruded to close a marrow cavity so as to reduce bleeding, so that the original complicated operation specifications are optimized and combined to further reduce bleeding during operating; therefore, the problem of more bleeding during operating is preferably solved and the time of the operation is reduced. Through extruding the vertebral spongy bone, the density of osteotomy vertebral spongy bone can be increased and bone healing is promoted.

Description

Extrusion pressing type spinal vertebral osteotome

Technical field:

This utility model belongs to medical instruments field, is specifically related to a kind of extrusion pressing type spinal vertebral osteotome.

Background technology:

At present spinal osteotomy hemorrhage many, easily overtax one's nerves that the osteotomy of a difficult problem, especially vertebral body through being spinal operation is hemorrhage morely to be made some operation termination or change into front and rear combinedly, enlarged wound and risk.

Existing osteotome only has the cutting function of machinery, and size decides with its width in accordance with international practices, and major product is divided into large, medium and small model.Also have according to shape and be divided into circle, flat cutter or twolip and single-blade.So the relatively applicable and spinal operation of spinal column osteotome (Tian Shi VI type) comparatively speaking, but the cutting that they can only machinery are hemorrhage more in the operation.

Summary of the invention:

This utility model is hemorrhage more shortcoming when performing an operation for the osteotome of prior art, and the principle according to clinical needs and vertebral arch pedicle of vertebral column dissection provides a kind of extrusion pressing type spinal vertebral osteotome that can solve preferably bleeding problems.

This utility model is implemented by the following technical programs:

Extrusion pressing type spinal vertebral osteotome of the present utility model is characterized in that, comprises the osteotome bar that hits perpendicular handle and be fixedly linked with the perpendicular handle of strike, and the end of osteotome bar also is fixed with the cutter head of arc.

Extrusion pressing type spinal vertebral osteotome of the present utility model is to use like this: the inside and outside cortical bone that exposes pedicle of vertebral arch after clipping the vertebral plate transverse process, the pedicle center digs into to cone center line and veutro with the arc osteotome, guarantee to carry out at spongy bone, and to side oscillation osteotome compacting cancellous end to end bone density is increased, the hemorrhage minimizing that diminishes of osteotomy section bone marrow trabecular space.Get final product until in vertebral body, be ' V ' shape.Replaced the step of striking off spongy bone or abrasive drilling polishing.Last corresponding ' V ' removes vertebral body side cortical bone.

Extrusion pressing type spinal vertebral osteotome of the present utility model can push the vertebral bone spongiosa and come closed medullary cavity hemorrhage to reduce on spinal vertebral osteotomy basis, with the optimum organization of original complex operations rules, hemorrhage when further reducing art, thereby solved preferably hemorrhage many problems in the operation, reduced the operating time of operation.Extruding vertebral bone spongiosa also can make osteotomy vertebral bone spongiosa density increase, and promotes knitting.

Description of drawings:

Fig. 1 is the structural representation of extrusion pressing type spinal vertebral osteotome of the present utility model;

Wherein 1, osteotome bar; 2, hit perpendicular hands handle; 3, cutter head.

The specific embodiment:

Following examples are to further specify of the present utility model, rather than to restriction of the present utility model.

As shown in Figure 1, extrusion pressing type spinal vertebral osteotome of the present utility model comprises the osteotome bar 1 that hits perpendicular handle 2 and be fixedly linked with the perpendicular handle 2 of strike, and the end of osteotome bar 1 also is fixed with the cutter head 3 of arc.

Above-listed detailed description is that this embodiment limits claim of the present utility model for the specifying of this utility model possible embodiments, and does not allly break away from the equivalence that this utility model does and implements or change, all should be contained in the claim of this case.

Claims

1. an extrusion pressing type spinal vertebral osteotome is characterized in that, comprises the osteotome bar that hits perpendicular handle and be fixedly linked with the perpendicular handle of strike, and the end of osteotome bar also is fixed with the cutter head of arc.
