Side-lying position traction device for shoulder arthroscopy

Abstract

The invention provides a side-lying position traction device for shoulder arthroscopy. The side-lying position traction device comprises a traction mechanism (100), an adjustment mechanism (200) and awheel component (300). The traction mechanism (100) is connected with the adjustment mechanism (200). The adjustment mechanism (200) is mounted on the wheel component (300). The traction mechanism (100) comprises a retractable cantilever (103), a support frame (113) and a gear adjustment component (107). The retractable cantilever (103) is connected with the support frame (113). The gear adjustment component (107) is mounted on the support frame (113). The side-lying position traction device for the shoulder arthroscopy has the advantages that the side-lying position traction device can be simply fastened to a rail of an operating table through a locking and fastening clamp block, and fastening and unfastening can be realized only through an adjusting nut; the device is simple and convenient in structure, easy to process, and easy to mount and demount.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lateral position traction device for shoulder arthroscopy. Background technique [0002] In shoulder arthroscopic surgery, the correct posture of the patient is very important to the safety of the patient, and it also provides a guarantee for the operator to smoothly enter the Menghumeral joint and the subacromial space for operation. Improper posture may limit the operation of the surgeon and interfere with the use of surgical instruments, as well as affect the accurate positioning of the surgical approach and the anatomical disposal of the traction lines of the limbs, and even cause complications of compression and stretching of the nerves. The side-lying traction device for shoulder arthroscopy can slightly change the patient's body position to facilitate the operation of surgical instruments, and correct the menghumeral joint edge to a horizontal position. In addit...
