Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a traction rope capable of displaying tension used in a shoulder joint abduction frame. Background Art

[0002] Arthroscopic shoulder surgery has been vigorously developed for the treatment of various shoulder joint diseases. However, arthroscopic shoulder surgery often requires traction of the affected limb in abduction, flexion, and internal rotation. At this time, a continuous and stable abduction traction frame for the affected limb is required to complete the surgery smoothly and quickly.

[0003] When patients undergo minimally invasive shoulder surgery, they need to traction their shoulders to fix their shoulders. Existing shoulder traction devices have poor stability during use, are difficult to install and disassemble, and cannot directly observe the traction force. Therefore, we propose a traction rope with displayable tension for a shoulder abduction frame. Utility Model Content
