Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a traction device for shoulder arthroscopic surgery. Background Art

[0002] Shoulder arthroscopy is a minimally invasive procedure used to diagnose and treat various conditions within the shoulder joint. It is performed through a small incision in the shoulder. A long, thin instrument called an arthroscope is inserted. This instrument, equipped with a light and camera, transmits images of the inside of the shoulder joint to a monitor, allowing the surgeon to view and address the problem in detail.

[0003] For example, a traction device for minimally invasive shoulder arthroscopy surgery is disclosed in Chinese patent publication number (CN109528256A), which states: "The traction device for minimally invasive shoulder arthroscopy surgery, by providing a first threaded rod, a threaded sleeve and a second threaded rod, can adjust the distance between the first threaded rod and the second threaded rod by rotating the threaded sleeve when pulling the arm, thereby achieving fine-tuning of the traction rope during pulling, and avoiding secondary damage to the patient's shoulder." It also states: "Minimally invasive shoulder arthroscopy surgery requires the patient to lie on his side and use auxiliary traction equipment to open the joint space of the patient's shoulder joint before the surgical operation can be performed. Generally, a traction rope is used for oblique traction, but the degree of traction of the traction rope is adjusted entirely by the doctor's experience during traction, and the traction rope is not convenient to fine-tune during pulling, which can easily cause secondary damage to the patient's shoulder." Technical problems.

[0004] In summary, the device still has the following technical problems: the device can adjust the height by adjusting the telescopic rod and the threaded sleeve, but since shoulder arthroscopic surgery generally repairs the ligaments at the shoulder joint, it is necessary to adjust the angle of the device during use to achieve the purpose of adjusting the angle of the patient's arm. The device can only adjust the height of the arm and cannot achieve multi-angle adjustment. For this reason, it is necessary to propose a shoulder arthroscopic surgery traction device to provide a new technical solution to solve the technical problems mentioned in the above patents.
