[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This utility model provides a tension band pin anti-accidental puncture structure. Through the cooperation of the pin anti-puncture component and the locking component, the two ends of the pin can be temporarily locked and protected during use, making it less likely to fall off and preventing accidental puncture. After use, the anti-puncture structure can be directly removed without affecting the normal use of the pin and preventing accidental puncture. After the entire structure is used, it can be disinfected for use in the next surgery.

[0026] Figure 1 , Figure 2 , Figure 3 The diagram shown is an overall structural schematic of one embodiment of the tension band pin anti-accidental puncture structure of this utility model. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 The main structure of this embodiment includes: a pin-tightening component and a locking component.

[0027] The pin puncture component is used in conjunction with the locking component. Specifically, the pin puncture component includes a puncture cylinder 11, a mounting cylinder 12 located below the puncture cylinder 11, and a threaded cylinder 13 corresponding to the puncture cylinder 11.

[0028] In practical use, the locking assembly is installed and used based on the puncture cylinder 11, the mounting cylinder 12 and the threaded cylinder 13 to achieve the puncture effect. The puncture cylinder 11 and the mounting cylinder 12 are designed as separate units, which facilitates disassembly and subsequent disinfection for recycling.

[0029] The locking assembly is used to lock the pin-tightening assembly. Specifically, the locking assembly includes an arc-shaped spring plate 23 fixed to the bottom surface of the pin-tightening cylinder 11, an arc-shaped plate 24 fixed to the end of the arc-shaped spring plate 23, an external thread 25 opened on the arc-shaped plate 24, a threaded ring 22 fixed to the top surface of the pin-tightening cylinder 11, and an internal threaded groove 21 opened on the bottom surface of the pin-tightening cylinder 11.

[0030] In practical use, the internal threaded groove 21 and the threaded ring 22 are connected to each other. At this time, the puncture cylinder 11 and the installation cylinder 12 form a whole. Then, the user directly presses down on the puncture cylinder 11. At this time, the tip of the pin is inserted into the middle position of the distributed arc-shaped spring plates 23 until the shank of the pin is inserted into the middle position of the arc-shaped spring plates 23. In this way, the arched surface of the arc-shaped spring plates 23 can press the shank of the pin tightly. Then, the user rotates the threaded cylinder 13, which is connected to the external thread 25. In this way, the distributed arc-shaped spring plates 23 are gathered and locked together. At this time, the puncture cylinder 11 can be limited and locked at the shank of the pin, avoiding the problem of the doctor accidentally touching the tip of the pin when installing the tension band.

[0031] Furthermore, it also includes auxiliary components, including a conical cap 31 disposed inside the accidentally punctured cylinder 11 and an annular baffle 32 fixed to the bottom surface of the conical cap 31;

[0032] The auxiliary components also include a spring 33 that connects the annular baffle 32 to the mis-punctured cylinder 11, and a rubber pad is provided inside the conical cap 31;

[0033] In actual use, the tip of the pin is directly inserted into the conical cap 31. As it moves forward, the spring 33 is compressed to buffer the entry of the pin, preventing the tip of the pin from directly hitting the inner top surface of the accidentally punctured cylinder 11 and causing the tip to break, thus improving the safety of use.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
