Multifunctional cervical and lumber vertebra retractor

Abstract

The invention discloses a multifunctional cervical and lumber vertebra retractor and belongs to the technical field of traction equipment. The multifunctional cervical and lumber vertebra retractor ischaracterized in that two long boards are arranged at the bottom of a lying plate, the long boards are fixed on the lying plate by virtue of a fixed hinge, the two long boards are respectively provided with one clamping belt, the two long boards are also connected with a circular cover at the bottom, a sucking disc is arranged in the middle of the lying plate, the sucking disc is connected with an air sucking device arranged in the laying plate, the air sucking device is respectively connected with the air outside the lying plate and the sucking disc by virtue of exhaust pipes, one headrest is also arranged at the upper part of the lying plate, a transmission shaft and a center shaft which are vertically connected are also arranged in the lying plate, and the transmission shaft is connected with a handle outside the lying plate. The multifunctional cervical and lumber vertebra retractor is multifunctional, can be used when a person lies flat and also can be used when the person stands.

Description

Technical field [0001] The invention relates to the technical field of medical equipment and 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 various types of cervical traction devices suitable for the treatment and rehabilitation of cervical spondylosis. The traditional cervical traction device uses a heavy hammer traction mechanism to control the traction force. Another improved method is to use the patient's own weight to traction by adjusting the height of the traction suspension mechanism. Chinese utility model patents CN200920031500, CN201020500180 and CN201020302355 disclose three common structures of manual and self-adjusting cervical traction devices that utilize the patient's own weight for traction; Chinese utility model patent CN200820238138 discloses a shoulder-type spiral cervica...

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
