Description

Kirschner wire protective cap structure

Technical Field

The utility model relates to an orthopedics nursing technical field, in particular to kirschner wire protective cap structure.

Background

The kirschner wire is an internal fixation material commonly used in clinical orthopaedics and hand surgery at present. When an orthopedist fixes the fracture reduction of the hand by using the kirschner wire, the orthopedic doctor often needs to cut off the kirschner wire and expose the tail end of the kirschner wire on the surface of the skin. The limb-strengthening scar is tired due to the fact that the tail end of the Kirschner wire exposed outside clinically can be injured by the patient through unconscious actions, and the tail end of the Kirschner wire can sometimes scratch the cotton quilt of the surrounding clothes. The protection cap that generally adopts at present is on the kirschner wire tail end, but, because protection cap and kirschner wire tail end are connected poorly, the patient is very easily rubbed off when using.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a ke shi needle protective cap structure to solve one or more technical problem that exist among the prior art, provide a profitable selection or creation condition at least.

The utility model provides a solution of its technical problem is: a k-wire protective cap structure comprising: the first rubber half body is provided with a first groove, the second rubber half body is provided with a second groove, the first rubber half body is provided with a first threaded hole, the second rubber half body is provided with a second threaded hole, the first groove and the second groove are matched and used for wrapping the tail end of a Kirschner wire, the first threaded hole and the second threaded hole are matched and the screw is connected with the first threaded hole and the second threaded hole.

Further, the surface of the first rubber half body is covered with a first silica gel layer.

Further, a second silica gel layer covers the surface of the second rubber half body.

Further, the screw is a cross screw.

Further, the screw is a straight screw.

The utility model has the advantages that: the protective cap is formed by the first rubber half body and the second rubber half body, the tail end of the Kirschner wire is prevented from injuring a patient, the first rubber half body and the second rubber half body are firmly sleeved at the tail end of the Kirschner wire in a screw thread connection mode, and the problem that the protective cap is easy to fall off is solved.

Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.

Embodiment 1, referring to fig. 1, 2 and 3, a kirschner wire protective cap structure includes: the first rubber half body 100 is provided with a first groove 120, the second rubber half body 200 is provided with a second groove 220, the first rubber half body 100 is provided with a first threaded hole 110, the second rubber half body 200 is provided with a second threaded hole 210, the first groove 120 and the second groove 220 are matched and used for wrapping the tail end of a Kirschner wire, the first threaded hole 110 and the second threaded hole 210 are matched, and the screw is connected with the first threaded hole 110 and the second threaded hole 210.

In operation, the first rubber half 100 and the second rubber half 200 clamp the tail end of the k-wire. Specifically, the tail end of the k-wire is placed into the first groove 120 and the second groove 220, and at this time, the tail end of the k-wire forms interference with the inner wall of the first groove 120 and the inner wall of the second groove 220. The tail end of the k-wire is securely sleeved for the first rubber half 100 and the second rubber half 200. The screw is connected with the first threaded hole 110 and the second threaded hole 210, so that the inner wall of the first groove 120 and the inner wall of the second groove 220 are deformed to press the tail end of the kirschner wire, the friction force between the first rubber half 100 and the second rubber half 200 is enhanced, and the first rubber half 100 and the second rubber half 200 firmly sleeve the tail end of the kirschner wire.

The utility model discloses a first rubber halfbody 100 and second rubber halfbody 200 form the protective cap, have avoided the tail end of ke shi needle to injure the patient to utilize the threaded connection mode of screw, with the firm cover of first rubber halfbody 100 and second rubber halfbody 200 at the tail end of ke shi needle, solved the problem that the protective cap drops easily.
