Cervical facet joint dislocation massage instrument

PendingCN111135048ASimplify the design and manufacturing processSimple preparation processRoller massageSuction-kneading massageCervical facet jointsEngineering
The invention relates to a cervical facet joint dislocation massage instrument. In order to solve the problem that because the current product is wrapped around the neck, in order to realize the up and down pulling of a distance of each joint of the cervical spine, and restore each joint to a correct position, the mandible must be moved up and down together, but an up and down movement range of the flexible mandible is relatively large after bearing a force, it is difficult to coordinate with each joint of the cervical spine, and thereby satisfactory treatment effects cannot be achieved, the cervical facet joint dislocation massage instrument is proposed. The massage instrument comprises a head support frame, a neck bracket, a telescopic support frame, adjustment support frames, and massage mechanisms. The design has simple making process and low cost, the making cost is saved while making more people affordable, an interval between the head support frame and the neck bracket can be adjusted to adapt to people with different neck lengths and thicknesses, the tail of the neck support frame, namely the neck end, is provided with the adjustment support frames, the ergonomics is easierto fit, a neck position fixing apparatus is abutted against to ensure that the apparatus cannot fall off, the massage mechanisms follow the trend of manual massage, it is more in line with the traditional Chinese medicine skill, and the effect is better.
