Description

Technical Field

[0001] The utility model relates to the technical field of arthroscopy, in particular to an arthroscopy with a flexible probe. Background Art

[0002] Arthroscopy is a rod-shaped optical instrument with a diameter of about 5mm for observing the internal structure of joints. It is an endoscope used to diagnose and treat joint diseases. The arthroscope is equipped with a lens at the end of a thin tube. When the thin tube is inserted into the joint, the internal structure of the joint will be displayed on the monitor. Therefore, the internal structure of the joint can be directly observed. Arthroscopy is not only used for the diagnosis of diseases, but has also been widely used in the treatment of joint diseases. When performing an arthroscope, it is necessary to inject anesthetics at the joint position, then use a scalpel to cut an incision in the joint skin, and then insert the head of the arthroscope into the incision. The doctor operates the arthroscope to take real-time images of the joint lesion.

[0003] However, the heads of common arthroscopes are straight. During arthroscopic irradiation, doctors need to rotate and adjust the arthroscope in real time to maintain the best irradiation angle. However, during long-term operations, doctors need to adjust the arthroscope in real time. The entire operation and irradiation process is rather cumbersome and the wrist is particularly prone to fatigue.

[0004] In view of the above problems, the present utility model is proposed. Utility Model Content
