A kind of fixed chair for medical cervical spine rehabilitation

Abstract

The invention discloses a fixing chair for medical cervical vertebra rehabilitation, wherein the upper part of a hydraulic cylinder is hermetically and slidably connected with a piston rod, the upperpart of the piston rod is fixedly connected with a lifting plate, two sides of the lower part of the lifting plate are respectively provided with a through groove, a fixing rod is sleeved with the through groove, and the lower end of a fixing rod is fixedly connected with a bottom plate; the back surface of the lifting plate is provided with a screw rod, the lower part of the screw rod is sleevedwith a sleeve, the sleeve is fixedly connected with the lower part of the lifting plate, the upper thread of the screw rod is connected with a threaded cylinder, the upper end of the threaded cylinderis fixedly connected with sliding legs, and the sliding legs are slidably connected to a guide groove, and the guide groove is arranged on the back surface of the upper part of the lifting plate. Thefixing chair drives the piston rod to retract through a hydraulic cylinder so as to to drive the lifting plate to lift, the cylinder and a clamp are driven to lift to achieve the height adjustment, meanwhile, the rotating screw rod drives the threaded cylinder to slide along the guide groove under the action of the thread, the upper end of the longitudinal moving threaded cylinder drives the cylinder to swing to adjust the inclination angle by using a connecting rod to achieve the adjustment function of the inclination angle, and the air pressure in the cylinder is controlled to drive the push rod to slide back and forth.

Description

technical field [0001] The invention relates to a medical device, in particular to a fixed chair for medical cervical spine rehabilitation. Background technique [0002] Cervical spondylosis, also known as cervical syndrome, is a general term for cervical osteoarthritis, hypertrophic spondylitis, cervical nerve root syndrome, and cervical disc herniation. It is a disease based on degenerative pathological changes. Mainly due to long-term cervical strain, bone hyperplasia, or intervertebral disc herniation, ligament thickening, cervical spinal cord, nerve root or vertebral artery are compressed, and a series of clinical syndromes of dysfunction appear. Manifested as vertebral instability and loosening; nucleus pulposus herniation or prolapse; bone spur formation; ligament hypertrophy and secondary spinal canal stenosis, etc., which stimulate or compress adjacent nerve roots, spinal cord, vertebral artery and cervical sympathetic nerves, etc. Causes a range of symptoms and si...

Problems solved by technology

[0003] At present, in the process of cervical spondylosis treatment and rehabilitation, it is often necessary to use a cervical collar to fix and maintain the neck, which can correct and restore the cervical spine. However, the existing neck collar is fixed on the neck, and the neck collar is used to keep it relatively fixed with the body. , can not achieve absolute fixation, and the existing neck collar is not adjustable for the pitch angle, and there are many inconveniences in use
