Multidirectional shoulder arthroscopy operative position regulating system

Abstract

The invention relates to a multidirectional shoulder arthroscopy operative position regulating system. The multidirectional shoulder arthroscopy operative position regulating system comprises a lifting and positioning device, a steering regulating device and a depression / elevation angle regulating device, as well as a counterweight and a traction hook; the lifting and positioning device is a bed rail locking mechanism formed by use of a rack assembly, and the bed rail locking mechanism comprises left and right gear boxes, a lateral locking handle gear drive node, and a fixing mechanism composed of a lateral locking bolt and a bed rail clamping plate assembly and connected with an operating bed; the steering regulating device is a steering regulating mechanism arranged on a round tube, and the steering regulating mechanism is a hand-operated steering mechanism composed of a worm gear, a worm, a steering regulating handle and the like and is connected with the lower end of the round tube by use of the worm gear to form a round tube rotating revolving mechanism; the elevation angle regulating device comprises a cantilever rod, an elevation angle regulating screw and a regulating hand wheel; the cantilever rod is set up into a lever mechanism by use of a U-shaped connection block; the counterweight is suspended at one end of the cantilever rod, while the traction hook is arranged at the other end of the cantilever rod.

Description

technical field [0001] The invention relates to a body position adjustment device for arthroscopic surgery, in particular to a multi-directional surgery body position adjustment system which can be used for multi-directional traction of a patient's arm during side-lying shoulder arthroscopic surgery, belonging to surgical operation auxiliary devices. Background technique [0002] During shoulder arthroscopic surgery, it is necessary to use various traction devices or surgical frame systems to traction the patient's arm to ensure the flexibility of the arthroscope and various surgical instruments in the joint cavity. [0003] Due to the thick muscles of the shoulder joint, the complex bony structure, the adjacent parts have more blood vessels and nerves, and the shoulder joint has a greater degree of freedom of movement; if there is no suitable surgical traction frame system, the shoulder joint space is small, and arthroscopy and surgery Instruments will be difficult to maneu...

AI Technical Summary

Problems solved by technology

[0004] However, due to factors such as individual differences in the human body, if the patient's affected area is located in a narrow shoulder joint, the existing traction frame for lateral position surgery on the market cannot guarantee shoulder arthroscopic surgery due to insufficient mobility. The degree of freedom necessary for the operation of arthroscopy and surgical instruments is not conducive to the smooth progress of the entire operation
