[0021] Example:

[0022] The following is combined with Figure 1 -4 Provide further details of this application.

[0023] The embodiment of the present application discloses a humeral intramedullary nail cable system, comprising: an intramedullary nail main nail 1, a tension nail 2 and a titanium cable 3; the intramedullary nail main nail 1 is arranged at the middle and upper part of the humerus 4, there are two tension nails 2 in a cross shape that penetrate the upper end of the humerus 4 and are detachably connected to the upper end of the intramedullary nail main nail 1; the titanium cable 3 is wound around the upper end of the humerus 4 and the head and tail ends of the titanium cable 3 are detachably connected to the tension nail 2.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The tension nail 2 includes a tension nail main nail 5 and a sealing cap 6; the tension nail main nail 5 penetrates the humerus 4 and is detachably connected to the intramedullary nail main nail 1, and a sealing cap 6 is detachably provided on the other end of the tension nail main nail 5, and the titanium cable 3 is located at the connection between the sealing cap 6 and the tension nail main nail 5; the setting of the sealing cap 6 can protect and fix the connection between the tension nail main nail 5 and the titanium cable 3, thereby increasing the stability and safety of the system.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A cross groove 7 is provided at the connection between the tension nail 2 and the sealing cap 6, and a thread is provided in the groove, and the sealing cap 6 is threadedly connected to the cross groove 7; the tightness of the connection between the tension nail 2 and the sealing cap 6 can be enhanced, and the sealing cap 6 can be prevented from loosening or falling off during use, thereby improving the stability and reliability of the system.

[0026] The implementation principle of the cable system for the intramedullary nail of the humerus 4 in the embodiment of the present application is as follows: the system sets the main nail of the intramedullary nail 1 at the middle and upper part of the humerus 4, and uses the tension nail 2 to penetrate the upper end of the humerus 4 and detachably connect with the upper end of the main nail of the intramedullary nail 1, and then uses the titanium cable 3 to wrap around the upper end of the humerus 4 and detachably connect with the tension nail 2, thereby achieving the fixation and stabilization of the humerus 4.
