Description

Postoperative cervical vertebra posterior muscle group training rehabilitation device

Technical Field

The invention relates to the technical field of cervical vertebra postoperative rehabilitation equipment, in particular to a postoperative cervical vertebra posterior muscle group training rehabilitation device.

Background

The post-operation rehabilitation treatment of cervical spondylosis is an important part of treatment, and particularly the rehabilitation process within 3 months after the operation is related to the prognosis effect of the operation. The purpose of rehabilitation after cervical vertebra surgery is to provide an ideal environment for nerve function recovery or bone healing. According to the difference of the incision approach, the operation can be divided into anterior cervical vertebra operation and posterior cervical vertebra operation. For anterior cervical surgery, a patient is generally required to wear a neck support to limit the cervical vertebra to move for more than 4 weeks, and the bony fusion between the vertebral bodies is ensured. When a patient wears the neck support, the cervical vertebra back muscle group can be easily disused and atrophied due to difficult movement and lack of rehabilitation exercise, so that the neck part can be sore and the like.

For posterior cervical spine surgery, the neck support is required to be worn strictly for 4-8 weeks in general, and since muscles behind the cervical spine are damaged in the surgery process, rehabilitation training is necessary in the rehabilitation process. The existing mode is that mostly put both hands alternately at the position behind the pillow through the patient oneself, power back up the head, both hands are simultaneously supported the occipital part with doing all can and make the head can not pitch back, reach the effect of training neck muscle through head and both hands antagonism promptly, but do not have an automatic equipment that can combine the neck brace at present to realize neck muscle training, for this reason we propose a postoperative cervical vertebra way of escape muscle crowd training rehabilitation device and be used for solving above-mentioned problem.
