A kind of orthopedic knee arthroscopic joint spreader

Abstract

An orthopedic knee arthroscopic joint spreader, comprising a hollow cylindrical extension column, the front end of the extension column is provided with a control panel that can swing up and down, and the top and bottom ends of the control panel are provided with a vertically movable, front and back swing The extension head; the outer circumference of the rear end of the extension column is rotatably connected with a disc-shaped rotating disk, the rear end surface of the extension column is fixedly connected with a pointer plate, and the rotating disk is hinged on the inner side of the ring-shaped positioning ring. The left and right ends of the positioning ring are provided with inserting plates that can move back and forth. The front ends of the inserting plates are hinged with clamping plates that can swing left and right. The bottom ends of the clamping plates are connected by a clamping belt. The left and right ends of the clamping belt The clamping plate protrudes and attaches with Velcro. The invention effectively solves the problem that the spreader has too high requirements on the incision in the current knee arthroscopic operation, and the spreader cannot effectively stretch the patient's knee joint for a long time.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an orthopedic knee arthroscopic arthroscopic spreader. Background technique [0002] Arthroscopic surgery is to insert a lens metal tube with a lighting device into the joint cavity through a small incision, and enlarge the internal structure of the joint cavity on a monitor to observe the pathological changes and locations in the joint cavity, and at the same time monitor the joint cavity under the monitor of the TV. Perform a thorough inspection and clean up the lesion. Arthroscopy is a minimally invasive surgery with both diagnostic and therapeutic functions. [0003] Knee arthroscopic surgery requires the use of a joint spreader to expand the patient's knee joint during diagnosis or treatment, so that the lesion or injury in the patient's knee joint is exposed to the knee arthroscope, which is convenient for diagnosis and treatment. However, most of the joint spreaders curren...
