Multifunctional cervical vertebra and lumbar vertebra retractor

Abstract

The invention discloses a multifunctional cervical vertebra and lumbar vertebra retractor and belongs to the technical field of traction equipment. According to the multifunctional cervical vertebra and lumbar vertebra retractor, two long plates are arranged at the bottom of a lying plate, the long plates are fixed to the lying plate through fixing hinges, each long plate is provided with a clamping belt and further connected with a circular ring sleeve at the bottom, a suction disc is arranged in the middle of the lying plate, the suction disc is connected with an air suction device arranged inside the lying plate, the air suction device is connected with air outside the suction disc and air outside the lying plate through a vent pipe, a headrest is further arranged on the upper portion of the lying plate, a transmission shaft and a central shaft which are connected perpendicularly are further arranged in the lying plate, and the transmission shaft is connected with a handle outside the lying plate. The multifunctional cervical vertebra and lumbar vertebra retractor is diversified in function and can be used when a person lies and can also be used when the person stands.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a multifunctional cervical and lumbar traction device. Background technique [0002] Cervical traction is the most important and effective method in the conservative treatment of cervical spondylosis. There are already various types of cervical traction devices suitable for the treatment and rehabilitation of cervical spondylosis. The traditional cervical traction device adopts a heavy hammer traction mechanism to control the traction force. Another improved method is to use the patient's own body weight for traction by adjusting the height of the traction suspension mechanism. Chinese utility model patents CN200920031500, CN201020500180 and CN201020302355 disclose three common structures of manual self-adjusting cervical tractors that use the patient's own body weight for traction; Chinese utility model patent CN200820238138 discloses a shoulder-type spiral cervical tr...

AI Technical Summary

Problems solved by technology

Constrained by the bone structure of the cervical spine, the control accuracy of the traction stroke of the cervical spine is at the millimeter level. According to the principles of physics, the traction stroke of the fixed pulley traction device is equal to the moving distance of the free end of the traction rope. Therefore, these two technical solutions are very Difficult to precisely control the traction stroke and traction force

Although CN201020302355 utilizes the worm gear on the support frame to realize the precise adjustment of the traction stroke and traction force, and CN200820238138 utilizes the screw transmission mechanism to realize the precise adjustment of the traction stroke and traction force, but the structure of the worm gear and the screw transmission mechanism is complicated, and the processing and manufacturing costs High, not conducive to its promotion and use
