An anterior cervical automatic retractor system

Abstract

The invention discloses an automatic anterior cervical vertebra hook drawing system comprises a centrum distraction assembly, a hook drawing assembly and a connecting and fixing assembly. The hook drawing assembly comprises a supporting rod, slide rails, a hook plate and a clamping device. The hook plate is installed on the two parallel slide rails, a clamping groove is formed in the upper surface of the tail end of the hook plate, the clamping device is fixedly arranged at the positions, close to the tail end of the hook plate, of the slide rails, the other ends of the slide rails are provided with the supporting rod perpendicular to the slide rails, a strip-shaped through hole is formed in the front end of the hook plate, and an installation hole is formed between he through hole and the clamping groove. The centrum distraction assembly comprises an osseous pin, a fixed rod, a distraction rod, a cross beam and a button. The fixed rod is fixed to the tail end of the cross beam, the distraction rod is movably connected with the cross beam, and the distraction rod is connected with a knob through a worm gear. The connecting and fixing assembly comprises grabbing hooks and a connecting rod, the grabbing hooks are movably connected with the connecting rod, and the connecting piece is arranged at the tail end of the connecting rod. The automatic anterior cervical vertebra hook drawing system can automatically pull anterior cervical vertebra soft tissue so as to expose the cervical vertebra, and emancipate people from heavy physical labor.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to an anterior cervical automatic retractor system. technical background [0002] There are many soft tissue structures such as the trachea and esophagus in front of the cervical spine. Anterior surgery needs to retract these structures to expose the cervical spine. At present, there are only ordinary retractors, which are very laborious to pull. If the operation is difficult or multiple cervical segments require surgery, it will be particularly laborious and the exposure effect will be poor after long-term stretching. In this operation, the vertebral body to be treated or the upper and lower vertebral body of the intervertebral disc should be stretched to increase the operating space; currently, an anterior cervical spreader is used to achieve this purpose. At present, there is no connection between common retractors and anterior cervical spreaders. Contents of the invention [000...
