Described on base, described retractor body is provided with polished rod, the two ends of this polished rod are fixed in described retractor body by polished rod back-up block, and described polished rod is socketed slide block, and this slide block is fixing with headrest, and force cell is installed in the end of headrest.
Described on base, between the polished rod back-up block of described slide block and described polished rod wherein one end, connect back-moving spring.
This utility model hinge structure has substantive distinguishing features and progress, specifically, retractor body of the present utility model is articulated and connected on underframe, turning certain angle, when to cervical vertebra treatment, conveniently locate focus accurately, the other end of retractor body installs rod assembly, this rod assembly and retractor body are slidably connected, the distance for the treatment of can be adjusted, adapt to the patient of different stature, headrest is slidably connected in this retractor body, conveniently traction therapeutic is carried out to head, wherein, force cell can the size of perception pull strength, adjust at any time, fixing band can fixing head effectively, headrest comprises headrest nest district and neck brace district, neck brace district comprises holder cervical region and rib, the corresponding human body head curve in headrest nest district arranges identical depression, when head is lain up, neck is contained in the neck brace portion in the middle of two grades of limits, neck brace portion, rib combines, the both sides of parcel neck and rear portion, rib gear is in the lower end of mandibular bone simultaneously, temporo jaw position is avoided to become Main Function point by pulling force, the pulling force be subject to is transferred to mandibular bone place, supported by neck brace, increase stress surface, protection temporo jaw, the structure of upset is in conjunction with rod assembly and the sliding headrest established, lesions position can be navigated to more accurately, therapeutic effect is given prominence to, meet No operation cervical vertebra location decompression treatment safety, painless, noinvasive, efficient treatment concept.
Further, traction apparatus adopts the mode of slide block to slide, and resistance to sliding is little, and structure is simpler, automatically controlled or manually all can operate.
Further, back-moving spring is installed, facilitates position reset, also prevent stretching transition, there is good protective effect.
It has design science, protection temporo jaw position, accurate, the comfortable reliable advantage of location focus.

Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
As Figure 1-3, a kind of cervical vertebra head traction device, comprise underframe 1 and one end and be hinged on retractor body 2 on this underframe 1, the other end of described retractor body 2 installs the rod assembly 13 be slidably connected with this retractor body 2, described retractor body 2 upper end is provided with the headrest 3 and fixing band that are slidably connected with this retractor body 2, described headrest 3 comprises headrest nest district 5 and neck brace district 6, described headrest nest district 5 has the depression of the curves of head when lying on the back with human body, described neck brace district 6 comprise holder cervical region 7 and be located at these holder cervical region 7 both sides for keeping off the rib 8 establishing jawbone position, the curve of cervical region when the inner laminating human body of described rib is lain on the back, described fixing band comprises forehead fixing band 4 and lower jaw fixing band 14.
As shown in Figure 4, described retractor body 2 is provided with polished rod 9, the two ends of this polished rod 9 are fixed in described retractor body 2 by polished rod back-up block 15, described polished rod 9 is socketed slide block 10, this slide block 10 is fixed with headrest 2, force cell 11 is installed in the end of headrest 2, connects back-moving spring 12 between the polished rod back-up block of described slide block 10 and described polished rod 9 wherein one end.
During use, this traction apparatus can use in conjunction with extension table, this traction apparatus is arranged on one end of a body, patient lies on a bed, before fixing head, first according to patient's height, the position of whole retractor body is determined by the length adjusting rod assembly 13, then head is placed on headrest 3, neck part is by neck brace district 6, be stuck in the U-shaped groove that neck brace portion 7 and rib 8 surround, the back side of head is placed on headrest nest district 5, lower jaw part nature is blocked by rib 8, lower jaw part becomes main stress point when cervical vertebra stretches, neck brace portion 7 and rib 8 are for providing the point of application of tensile force, then forehead fixing band 4 and lower jaw fixing band 14 is fixed, head is fixed on headrest 3, the cervical vertebra focus concrete according to patient, adjust the angle of whole retractor body 2, and headrest 3 applies the size of strength, patient is treated accurately, this equipment can realize differentiation treatment, different length is adopted for different patients, angle and stretching strength, and the stress point of human body is whole lower jaw part during owing to stretching, stressedly comparatively to disperse, there will not be the excessive problem causing pain of tensile force, for No operation cervical vertebra treatment, there is safety, painless, noinvasive, efficient advantage.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of this utility model request protection.
