Embodiment Construction

[0074] Such as Figure 28-31 , a kind of orthopedic Kirschner wire bender, the forming core block 1 is fixed on the base 5, the base 5 is provided with a block 19, the block 19 and the core block 1 form a groove 199 for clamping the Kirschner wire, and the base 5 The shifting block 6 connected with the shaft 21 is used to stir the Kirschner wires. During the shifting process of the shifting block 6, two faces of the shifting block 6 are in contact with the Kirschner wires, and the Kirschner wires are folded into a U-shaped bend. Since the shifting block 6 has two surfaces in contact with the Kirschner wires, the Kirschner wires can be folded into a U-shaped bend at a turning angle of the shifting block 6 less than 180 degrees;

[0075] The included angle between the two contact surfaces of the shifting block 6 and the Kirschner wire (that is, the right side and the lower side of the shifting block 6 in the figure) is less than 90 degrees such as Figure 32 . In this way, the...

Abstract

The invention discloses a kirschner wire bender for the department of orthopedics. According to the kirschner wire bender, a forming core block is fixedly arranged on a base, a shaft hole is formed in the base, a rotating shaft is arranged in the shaft hole and extends out of the shaft hole to form a limiting column, a kirschner wire is located jointly by the limiting column and the forming core block, and a poking block is fixedly arranged by the rotating shaft through a connecting member. In the prior art, a clamping head is adopted, the kirschner wire is always clamped firstly and then is bent powerfully in a clamped state, and thus, time and labor are consumed; according to the kirschner wire bender, a standard hook-shaped elbow is formed through poking the kirschner wire to be bent around the forming core block by the poking block which turns around the rotating shaft.

Description

technical field [0001] The invention relates to a surgical medical instrument, in particular to an orthopedic Kirschner wire bender. Background technique [0002] In orthopedic surgery, Kirschner wires are often used as steel needles for docking and fixing broken bones. Generally, Kirschner wires are about 20 centimeters in diameter, and there are several different specifications between 0.5 and 3 millimeters in diameter. It is used to fix small fractures or avulsion fractures and other fractures with low stress. It is also often used in the fixation of temporary fracture blocks in orthopedic surgery. During the operation, the Kirschner wires can be cut according to the size of the docking bone, and then inserted into the drilled bone for fixation, and the steel needles exposed outside the bone can be bent to prevent them from being left behind. The needle tail on the surface of the bone sticks out of the skin or sinks into the surface of the bone and cannot be removed late...
