Description

A kind of postoperative cervical spine posterior muscle group training and rehabilitation device

technical field

The invention relates to the technical field of rehabilitation equipment for cervical vertebra surgery, in particular to a rehabilitation device for training and rehabilitating muscles of the posterior cervical vertebrae after surgery.

Background technique

Rehabilitation after cervical spondylosis is an important part of the treatment, especially the rehabilitation process within 3 months after the operation is related to the prognosis of the operation. The purpose of rehabilitation after cervical spine surgery is to provide an ideal environment for neurological recovery or bone healing. According to the different incision approach, it can be divided into anterior cervical and posterior cervical surgery. For anterior cervical spine surgery, patients are generally required to wear a cervical collar to limit the movement of the cervical spine for more than 4 weeks to ensure the bony fusion between the vertebral bodies. In the process of wearing a cervical collar, patients are difficult to move and lack of rehabilitation exercises, which can easily lead to disuse atrophy of the muscles behind the cervical spine, resulting in neck pain and other postoperative sequelae.

For posterior cervical surgery, under normal circumstances, it is necessary to strictly wear a cervical collar for 4-8 weeks, and because the muscles behind the cervical spine are damaged during the operation, it is necessary to perform rehabilitation training on them during the rehabilitation process. Most of the existing methods are that the patient himself crosses his hands on the back of the occiput, tilts his head back with force, and at the same time presses the occiput with both hands to prevent the head from tilting back, that is, the neck muscles are trained by confrontation between the head and the hands. However, at present, there is no automatic device that can be combined with a cervical collar to realize neck muscle training. Therefore, we propose a posterior cervical muscle group training and rehabilitation device to solve the above problems.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a post-operative cervical muscle group training and rehabilitation device, so as to solve the problems raised in the above-mentioned background art.

In order to achieve the above purpose, the present invention provides the following technical solutions: a post-operative cervical vertebra posterior muscle group training and rehabilitation device, comprising staggered and fixed front cervical collar and rear cervical collar,

The outer side of the rear fixing part is provided with a force applying structure that exerts pressure on the back neck of the patient. Two freely rotatable sleeves are sleeved on the upper side in parallel, and the outer surfaces of the two sleeves are respectively fixed and connected with two different force-applying blocks through connecting rods. The two force-applying blocks are distributed up and down. They are in conflict with the rear neck support and the lateral side of the rear support respectively;

The force-applying structure also includes a power structure that drives the two force-applying blocks to reciprocate up and down, the power structure includes a housing fixed to the mounting frame, and two runners are installed in the housing, one of which is a runner. Driven by a torque motor installed on the casing, the runner is covered with an elastic band of no more than one circle, and the two ends of the elastic band are respectively connected with two force-applying blocks.

Preferably, the front fixing part and the rear fixing part are detachably connected by a Velcro.

Preferably, the rear neck support portion and the rear support portion are respectively connected to the rear fixing portion through elastic plastic connectors.

Preferably, the front air cushion and the rear air cushion are communicated through a plurality of connecting air nozzles with adjustable lengths.

Preferably, a concave escape groove is provided in the middle part of the inner side of the front air cushion.

Preferably, the two force-applying blocks are arc-shaped plate structures with the same shape, the force-applying blocks swing up and down around the axis of the rotating shaft, and supports are installed on the outer surfaces of the rear neck support portion and the rear support portion. The support plate is provided with a chute for sliding with the force-applying block.

Preferably, two through holes are formed on the side of the casing facing the force applying block, and one side of the runner passes through the through holes and extends to the outside of the casing.

Compared with the prior art, the beneficial effects of the present invention are:

In the present invention, the torque motor is used to start, and when the first runner is driven to rotate clockwise as shown in the figure, the first force-applying block will be pulled upward through the second elastic band, so that the first force-applying block will rotate upward and squeeze the back neck. The support plate of the support part drives the back neck support part to squeeze towards the neck, so as to exert pressure on the patient's occiput, at this time, the patient can train the muscles by resisting the pressure of the back neck support part.

When the first force-applying block rotates upward, the second force-applying block is also pulled through the first elastic band, so that the second force-applying block rotates downward, exerting pressure on the patient's shoulder, so that the patient opposes the back of the neck support. Under pressure, the neck brace can provide enough support.

The torque motor is also provided with a reducer, and the torque motor is controlled by the controller to rotate at a low speed and a small amplitude to avoid damage to the patient's neck caused by too fast rotation speed and too many turns.

In the present invention, the inflator inflates the front air cushion and the rear air cushion at the same time, and the front air cushion and the rear air cushion closely fit on the patient's neck after being inflated, and play a further role in fixing.

A concave escape groove is set in the middle part of the inner side of the front air cushion to avoid excessive squeezing force on the user's throat during use.
