Description

Kirschner wire bending device

Technical Field

The utility model relates to the field of medical equipment, concretely relates to kirschner wire bending machine.

Background

At present, the use of kirschner wires for fixing fracture blocks is a more common internal fixing mode in clinical orthopedic surgery, and the kirschner wires exposed out of bones are bent to prevent the needle tails left on the surfaces of the bones from piercing the skin or being submerged into the surfaces of the bones and being incapable of being taken out at a later date. The doctor usually uses the vice or the nipper pliers to bend the kirschner wire in the past, and the front end of the kirschner wire is easy to loosen or even pull the kirschner wire off from the bone surface when the vice or the nipper pliers are used for bending, and the kirschner wire is easy to rotate on the binding clip of the vice or the nipper pliers, and the kirschner wire deflects when the kirschner wire is bent, so that the phenomenon that the kirschner wire is not bent in place or even deviates is caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above-mentioned problem, designed a ke shi needle bending machine, this ke shi needle bending machine can effectively fix the ke shi needle, prevents that the ke shi needle from rotating and leading to deflecting, and the effect of buckling is better and can prevent that vice or sharp-nosed pliers from making the front end of ke shi needle take place not hard up the condition that can pull out the ke shi needle from the bone face even when bending.

In order to solve the above technical problem and achieve the above technical effect, the present invention is implemented by the following technical contents:

a Kirschner wire bender comprises a bending frame and a base. The bending frame is connected with the base through a rivet, the bending frame comprises a handle, a connecting plate and a pin inserting table, one end of the connecting plate is fixedly connected with the handle, the other end of the connecting plate is fixedly connected with the pin inserting table at a certain angle, and a through pin inserting hole is formed in the left side of the upper surface of the pin inserting table; the left side of the upper surface of the base is provided with a through pin hole, threaded holes intersected with the pin hole are formed in the front and the back of the side surface of the base, and flat head screws are arranged on the threaded holes.

Preferably, the bending angle between the connecting plate and the pin platform is 130 degrees.

Preferably, the middle of the front end of the needle inserting table is provided with a protruded L-shaped block body, the L-shaped block body is fixedly connected with the needle inserting table, two sides of the front end of the base are provided with protruded L-shaped block bodies, the L-shaped block body is fixedly connected with the base, and the rivet penetrates through the three L-shaped block bodies to be connected.

Preferably, the bending frame and the base are made of stainless steel.

The utility model has the advantages that: this ke shi needle bending machine can effectively fix the ke shi needle, prevents that the ke shi needle from rotating and leading to deflecting, and the effect of buckling is better and can prevent vice or sharp-nosed pliers from making the front end of ke shi needle take place not hard up or even can pull out the condition of taking off the ke shi needle from the bone face when bending.
