Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a Kirschner needle cap. Background Technology

[0002] In orthopedics, Kirschner wires are commonly used fixation materials, and often a portion of them needs to remain outside the body. However, the exposed ends of these Kirschner wires frequently cause numerous problems. On the one hand, medical staff are prone to being pricked by the exposed ends during medical procedures, which can cause skin damage and potentially lead to cross-infection. On the other hand, after discharge, patients and their families are also susceptible to being pricked by the exposed ends, causing significant inconvenience in daily life and potentially scratching clothing, bedding, etc., placing additional financial burden and disruption on the patient's family.

[0003] Currently, there are significant deficiencies in clinical protection measures for the tail end of Kirschner wires. For example, using a plastic sleeve attached to the tail end of the Kirschner wire is simple to operate, but the connection between the plastic sleeve and the Kirschner wire is unstable and easily falls off when the patient moves or is subjected to external impact, resulting in the failure of protection. Another method is to bend the tail end of the Kirschner wire and wrap it with adhesive tape, but this also cannot fundamentally solve the problem. Over time and with patient activity, the adhesive tape is prone to cracking and loosening, and cannot effectively protect the tail end of the wire in a long period of time, still posing a risk of puncture. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical problems and provide a Kirschner needle end cap.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a Kirschner wire end cap, comprising a hollow clamping screw and a protective cap, wherein the clamping screw has a conical structure and is composed of multiple clamping bodies for wrapping the end of the Kirschner wire, the protective cap is provided with a receiving hole, the side wall of the receiving hole is provided with an internal thread, and one end of the clamping screw is connected to the receiving hole so that the end of the Kirschner wire is received in the receiving hole.

[0006] Furthermore, a gap is left between adjacent clamping bodies.

[0007] Furthermore, the protective cap includes a cap body and a cap tip, with the cap tip disposed on the cap body and the cap tip being integrally formed with the cap body.

[0008] Furthermore, the cap body has a cylindrical structure.

[0009] Furthermore, the length of the cap body is the same as the length of the clamping screw.

[0010] Furthermore, the sidewall of the cap is provided with anti-slip ridges.

[0011] Furthermore, the clamping body has four clamping bodies.

[0012] As can be seen from the above description of this utility model, compared with the prior art, the Kirschner wire tail cap provided by this utility model has the following advantages: It is equipped with a clamping screw and a protective cap. The clamping screw is composed of multiple clamping bodies that can wrap around the tail end of the Kirschner wire. The protective cap has a receiving hole with internal threads on the side wall. By connecting the receiving hole to the clamping screw, the tail end of the Kirschner wire can be received in the receiving hole, effectively isolating the tail end of the Kirschner wire. Furthermore, because the protective cap is threadedly connected to the clamping screw, when the protective cap is tightened, the multiple clamping bodies will clamp the Kirschner wire, thus preventing it from moving or falling off. This avoids the problems of plastic sleeves easily falling off and adhesive tape easily breaking and failing, significantly reducing the risk of punctures or scratches to patients and their families. At the same time, because the clamping screw has a tapered structure, it can accommodate Kirschner wires of different diameters with a fixed diameter of the receiving hole, providing good versatility and avoiding the inconvenience of needing to equip multiple tail caps of different specifications due to different Kirschner wire diameters.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0016] Reference Figure 1 , Figure 2 As shown, a Kirschner wire tail cap includes a hollow clamping screw 1 and a protective cap 2. The clamping screw 1 has a conical structure and is composed of multiple clamping bodies 11 for wrapping the tail end of the Kirschner wire. The protective cap 2 has a receiving hole 211 with internal threads on its sidewall. One end of the clamping screw 1 is connected to the receiving hole 211 so that the tail end of the Kirschner wire is received in the receiving hole 211, which isolates the tail end of the Kirschner wire. Since the protective cap 2 is threadedly connected to the clamping screw 1, when the protective cap 2 is tightened, the multiple clamping bodies 11 will clamp the Kirschner wire, thereby preventing the Kirschner wire tail cap from moving or falling off. This avoids the problems of plastic sleeves easily falling off and adhesive tape easily breaking and failing, and significantly reduces the risk of patients and their families being pricked or scratched.

[0017] There is a gap between adjacent clamping bodies 11.

[0018] The protective cap 2 includes a cap body 21 and a cap tip 22, with the cap tip 22 disposed on the cap body 21 and integrally formed with the cap body 21. Specifically, the cap body 21 has a cylindrical structure.

[0019] The length of the cap 21 is the same as the length of the clamping screw 1.

[0020] The cap 22 has anti-slip textures 221 on its side wall. These textures increase the friction for medical staff when operating the Kirschner needle cap, preventing slippage, facilitating installation and disassembly, and improving the convenience and safety of operation.

[0021] Preferably, the clamping bodies 11 have four.

[0022] In use, the tail end of the Kirschner wire is inserted into the hollow portion of the clamping screw 1. Then, by rotating the protective cap 2, the clamping screw 1 engages with the internal thread of the receiving hole 211, thereby accommodating the tail end of the Kirschner wire within the receiving hole 211, achieving isolation and protection of the Kirschner wire tail end. Due to the tapered structure of the clamping screw 1, this Kirschner wire tail cap can accommodate Kirschner wires of different diameters, exhibiting wide applicability.

[0023] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
