Abstract

The utility model relates to a ke shi needle preflex ware, it includes handle (1) and establishes in the body of rod on hand (2), head (3) of this body of rod (2) are equipped with diameter unequal ke shi pinhole (4), a serial communication port, the head of the body of rod (2) is the flat structure, and the thickness of this flat structure is 1-2.5 mm, ke shi pinhole (4) establish in the flat structure. Less acute angle can be buckled into with the ke shi needle to this preflex ware to satisfy the operation requirement.

Description

A kind of Kirschner wire pre-bending device

Technical field

This utility model relates to a kind of surgical instruments, is specifically related to the device of the implantation inner fixer for synthetism.

Background technology

Kirschner wire fixation fracture is the methods of internal fixation commonly used clinically, needs to carry out tail end and bends with fixation Kel's needle, and avoid it to thrust sclerotin or subcutaneous after fixing.At present, the pre-bending Kirschner wire such as conventional needle holder, vice, needle-nose pliers in clinical, but, position little at otch is dark, be difficult to the tail end vising Kirschner wire.Although sometimes vised the tail end of Kirschner wire, rotation flexing movement cannot be done because otch is less.Sometimes also because the diameter of Kirschner wire is comparatively thick, and clamping force causes run-bake-needle fault not.Especially the such as fracture such as Patella fracture, olecranal fracture, fracture of medial malleolus, need Kirschner wire to be bent into less acute angle, the instruments such as needle holder, vice and needle-nose pliers are then difficult to be competent at, because the jaw of these instruments is wider, the radian of bending is bigger than normal.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of orthopaedics kirschner pre-bending device, and Kirschner wire can be bent into less acute angle by this pre-bending device, to meet requirements of operation.

The technical scheme that this utility model solves the problem is as follows:

A kind of Kirschner wire pre-bending device, it comprises handle and is located at the body of rod on handle, and the head of this body of rod is provided with the kirschner pin hole that diameter does not wait, and it is characterized in that, the head of the described body of rod is flat structure, and the thickness of this flat structure is 1 ~ 2.5 ㎜; Described kirschner pin hole is located in described flat structure.

The edge at described kirschner pin hole two is provided with circular arc chamfering, is beneficial to bending, and can obtains less bending angle.

The flat structure of to be thickness be 1 ~ 2.5 ㎜ of the head due to the body of rod of Kirschner wire pre-bending device described in the utility model, therefore be expert at rotate bending operation time, the bending radius of Kirschner wire can be limited in 1 ~ 2.5 ㎜ scope, obtain less acute angle, be beneficial to the internal fixation operation of the fracture such as row such as Patella fracture, olecranal fracture, fracture of medial malleolus.

Fig. 4 ~ Fig. 6 is the structural representation of another specific embodiment of Kirschner wire pre-bending device described in the utility model, and wherein Fig. 4 is front view, and Fig. 5 is left view, and Fig. 6 is B-B cutaway view Amplified image of Fig. 4.

Detailed description of the invention

Example 1

See Fig. 1 ~ Fig. 3, the handle 1 of the Kirschner wire pre-bending device of this example is horizontal handle, and the body of rod 2 is vertically located on the side of handle 1.Wherein, the head 3 of the body of rod 1 is flat structure, and the thickness of this flat structure is 1.5 ㎜, which is provided with the kirschner pin hole 4 that diameter is respectively 4mm, 3mm and 2mm.Due to when implementing to rotate bending operation, the distance stability far away leaving handle is poorer, and strength required for the larger bending of the diameter of Kirschner wire is larger, therefore three kirschner pin holes 4 are preferably by the size in aperture, from the far-end proximally ascending arrangement of the body of rod 2.

Example 2

See Fig. 4 ~ Fig. 6, the handle 1 of the Kirschner wire pre-bending device of this example is staight shank, and the body of rod 2 is coaxially located on the end face of handle 1.Wherein, the thickness of the flat structure of the body of rod 1 head 3 is 2.5 ㎜, which is provided with the kirschner pin hole 4 that diameter is respectively 4.5mm, 3.5mm and 2.5mm.The edge at kirschner pin hole 4 two in this example is provided with circular arc chamfering 5, and the radius of this circular arc chamfering 5 is 1.25mm.

Claims

1. a Kirschner wire pre-bending device, it comprises handle (1) and is located at the body of rod (2) on handle, the head (3) of this body of rod (2) is provided with the kirschner pin hole (4) that diameter does not wait, it is characterized in that, the head of the described body of rod (2) is flat structure, and the thickness of this flat structure is 1 ~ 2.5 ㎜; Described kirschner pin hole (4) is located in described flat structure.

2. a kind of Kirschner wire pre-bending device according to claim 1, is characterized in that, the edge at described kirschner pin hole (4) two is provided with circular arc chamfering (5).
