[0026] Referring to Figure 2 - Figure 4When assisting in the installation of the device on the patient's forearm, the auxiliary component 9 is activated. The auxiliary component 9 includes a guide rail 91, the rear surface of which is fixedly connected to the front surface of the support plate 8. A telescopic side plate 92 is slidably connected to the front surface of the guide rail 91. The operator can manually adjust the telescopic side plate 92 to move to the left in the guide rail 91, thereby reducing the distance between the upper arm and the device, and making appropriate adjustments to the patient's upper arm. The operator can also adjust the degree of stretching of the telescopic side plate 92 to make appropriate adjustments to the patient's forearm, increasing the applicability of the device. An adjustment block 93 is fixedly connected to the left surface of the telescopic side plate 92. An elastic rope 94 is detachably connected to the upper surface of the adjustment block 93. The elastic rope 94 works with the adjustment block 93 to fix the periphery of the patient's forearm and prevent the device from slipping. A grip ball 95 is rolledly connected to the front end of the upper surface of the telescopic side plate 92. The patient can release the emotional pressure during the traction surgery by gripping the grip ball 95, enabling the patient to cooperate more stably with the adjustment during the surgery, thus enriching the functionality of the device.

[0027] Working principle: When the patient undergoes surgical traction with their arm abducted, the traction component 3 is activated. As the patient's upper arm is raised, the support plate 8 moves upward, which in turn moves the support rod 36. This movement causes the support rod 36 to move the moving block 35 upward, which in turn moves the slider 37 upward in the groove 38. During the upward movement of the moving block 35, the telescopic rod 34 moves upward, putting it in a stretched state. When the patient's upper arm is raised to an angle exceeding approximately 30 degrees, the telescopic rod 34 is fully stretched. The upward movement of the telescopic rod 34 exerts a pulling force on the upper surface of the telescopic sleeve 31. The deformation of the telescopic sleeve 31 causes the telescopic thin rod 32 to stretch, putting the spring 33 in a stretched state. The reaction force of the spring 33 then combines with the pulling force of the telescopic sleeve 31, resulting in increasingly greater traction damping as the patient's upper arm continues to be raised. This enhances the effectiveness of the device in tractioning the incision. The resistance generated by spring 33 also provides corresponding protection against abduction of the patient's upper arm, preventing shoulder joint damage caused by excessive upper arm movement angle. This improves the protective effect of traction component 3 on the patient's shoulder joint. When assisting in the installation of the patient's forearm, the operator can manually adjust the telescopic side plate 92 to move to the left in the guide rail 91, thereby reducing the distance between the upper arm and the device, and making appropriate adjustments to the patient's upper arm. The operator can also adjust the stretching degree of the telescopic side plate 92 to make appropriate adjustments to the patient's forearm, increasing the applicability of the device and improving the patient's comfort after wearing it. The elastic rope 94, together with the adjusting block 93, fixes the outer periphery of the patient's forearm to prevent the device from slipping off. The patient can release emotional stress during traction surgery by gripping the grip ball 95, enabling the patient to cooperate more stably with the adjustments during the surgery, thus enriching the functionality of the device.

[0028] It should be pointed out finally that the above only for the preferred embodiments of the present application and is not intended to limit the present application, although the present application is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or equivalent replacement of some of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included within the scope of the present application.
