Kirschner wire bending device

Technical Field

The application relates to the technical field of medical instruments, in particular to a Kirschner wire bending machine.

Background

The k-wire is a commonly used internal fixation material for orthopaedics, is used for fixing short and small fracture or tear fracture and other fracture fixation with low stress, and is also used for fixing temporary fracture blocks in orthopaedics operation, and in order to prevent the k-wire from shifting, the end part of the fixed k-wire is often required to be bent. The traditional bending mode by using the tool pliers is inconvenient to operate and inconvenient to control the bending length of the end part of the Kirschner wire. To this end, the inventors propose a kirschner wire bender.

Detailed Description

Example 1

Referring to fig. 1-2, in the present embodiment, the kirschner wire bender includes a handle 11 disposed at a first end of an operation rod 10, and a chute 12 disposed at a second end of the operation rod 10, wherein the chute 12 extends along a longitudinal direction of the operation rod 10 as a whole, and a blind hole 13 is formed on a peripheral surface of the operation rod 10, which is close to the chute 12.

According to the embodiment, the Kirschner wire end 21 of the Kirschner wire 20 is inserted into the blind hole 13 with fixed depth, the rotating operation rod 10 can bend the Kirschner wire end 21, the bending length is fixed, the sliding groove 12 matched with the design is slidably clamped on the Kirschner wire 20, and the rotating operation rod 10 can bend the Kirschner wire at the target bending position 22, so that the device has the advantage of simplicity and convenience in operation.

It should be noted that, when bending the end 21 of the k-wire, the end 21 of the k-wire needs to be inserted into and abutted against the bottom of the blind hole 13, and the bending length of the end 21 of the k-wire is controlled by fixing the depth of the blind hole 13, which has the advantages of convenient operation and accurate bending length control.

It should be further noted that, since the sliding groove 12 is an open groove structure formed on the end surface of the second end of the operating rod 10, and the sliding groove 12 is integrally configured in a U shape, the sliding groove 12 may be clamped on the k-wire 20 and may move along the k-wire 20, so that the position of the target bending portion 22 may be more conveniently selected.

It should be understood that, by using the blind hole 13 and the chute 12 in combination, multiple bending of the k-wire 20 can be quickly completed, and when bending operation is performed on the k-wire 20 by using the blind hole 13 and the chute 12, the operation rod 10 can be quickly separated from the k-wire 20 after each bending operation is completed, so that the operation is simple and convenient.

In this embodiment, alternatively, the operating lever 10 is configured as a long round bar shape as a whole, the handle 11 is arranged vertically to the operating lever 10 as a whole, and by adding the handle 11, the rotation of the operating lever 10 can be more convenient and labor-saving.

In addition, the slide groove 12 is formed on the end face of the second end of the operation lever 10 and extends toward the handle 11 from the end face of the second end of the operation lever 10 by a certain distance, the slide groove 12 is arranged entirely along the diameter direction of the operation lever 10, that is, the slide groove 12 bisects the end face of the second end of the operation lever 10, the slide groove 12 has both side walls parallel to each other, that is, the slide groove 12 is configured in a rectangular shape in cross section, the blind hole 13 is arranged entirely on the operation lever 10 between the slide groove 12 and the handle 11, and for improving the ease of operation, the blind hole 13 is arranged near the slide groove 12, the axis of the blind hole 13 is held vertically to the axis of the operation lever 10 entirely, and the axis of the blind hole 13 is arranged entirely along the radial direction of the operation lever 10, the control range of the depth of the blind hole 13 can be enlarged, for improving the ease of operation, the axis of the blind hole 13 is held entirely parallel to the side walls of the slide groove 12, and the handle 11 is held vertically to the side walls of the slide groove 12 entirely.

While embodiments of the present application have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the application, and that variations, modifications, alternatives, and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the application.
