Shoulder arthroscopy lower retractor device

Abstract

The invention relates to a drag hook device under a shoulder arthroscope and relates to the technical field of medical instruments. The device comprises a sheath tube and a plurality of pull pieces, wherein the sheath tube is a tube body with the upper end and the lower end open, the pull pieces are in a vertical strip shape, the upper ends and the lower ends of the pull pieces are transversely bent in the same bending direction, and bent portions at the lower ends of the pull pieces are elastic; a plurality of vertical guide grooves are formed in the upper portion of the tube wall of the sheath tube, the guide grooves are distributed in the circumferential direction of the sheath tube at intervals, and when the bent portion of the upper end of the pull piece is inserted into the guide grooves, the bent portion of the lower end of the pull piece stretches out of a tube opening in the lower end of the sheath tube; the sheath tube is sleeved with a pushing nut and a positioning nut whichcan move up and down, the pushing nut and the positioning nut are both in threaded fit with the sheath tube, and the pushing nut is located above the positioning nut. The device provided by the invention is suitable for clinical shoulder arthroscopy surgery.

Description

technical field [0001] The invention relates to medical equipment technology, in particular to a technology of a shoulder arthroscope pull-down hook device. Background technique [0002] In shoulder arthroscopic surgery, due to the very limited operating field of view, especially when operating under the acromion, the muscle tissue and synovial tissue around the acromion often block the arthroscopic field of view, and excessive cleaning of soft tissues can easily cause bleeding. This makes the field of view even worse. Moreover, after changing the viewing angle, it is often necessary to clean the field of view again, which greatly delays the operation time. During rotator cuff surgery, it often takes a lot of time to clean up the surgical field of view, which will cause limb swelling and troubles such as unsmooth operation. Contents of the invention [0003] Aiming at the above-mentioned defects in the prior art, the technical problem to be solved by the present inventio...
