Embodiment Construction

[0030] In order to further explain the present invention, the implementation manners are described as follows with preferred specific examples and drawings:

[0031] figure 1 Among them, a spinal reduction device 10 with dual elastic coefficients of the present invention includes an outer sleeve 20 and an inner lining 30.

[0032] The outer sleeve 20 is a accommodating space 23 with a plurality of surrounding walls 21 connected to form an opening 22, and the front end of the outer sleeve 20 is a pointed design 24 for implanting an upper vertebral condyle 61 and a lower vertebra Section 62 is in the middle of the condyle of the spine (as shown in Figure 2). The inner liner 30 is a setting suitable for the shape of the accommodating space 23 of the outer sleeve 20, and is accommodated in the accommodating space 23 of the outer sleeve 20 through the opening 22.

[0033] The outer sleeve 20 is provided with a plurality of perforations 25 on the wall 21, and the inner lining member 30...

Abstract

The invention relates to a dual-elasticity coefficient spine reduction device, the dual-elasticity coefficient spine reduction device is used for being implanted into a spinal tissue, which comprises: an outer sleeve part, which is provided with an opening containing space, an inner liner part, which is contained in the containing space, and one end thereof is suitable to be connected with an implantation tool. The elasticity coefficient of the inner liner part is between 100 to 250GPa, and the elasticity coefficient of the outer sleeve part is between 2 to 22GPa. The inner liner part is contained in the outer sleeve part, after that, the reduction device is implanted into the spinal tissue by the implantation tool, and the outer sleeve part is contacted with the spinal tissue.

Description

Technical field [0001] The present invention relates to a spinal reduction device with dual elastic coefficients, in particular to a device that includes an outer sleeve and an inner liner fitted in the outer sleeve. The outer sleeve and the inner liner have different elastic coefficients. When in use, an outer sleeve close to the elasticity coefficient of the vertebral tissue contacts the vertebral tissue, and the inner liner provides a dual elasticity coefficient vertebral reduction device with support and turning force. Background technique [0002] Existing medical materials for vertebral distraction correction, such as the spine correction fixation device of U.S. Patent No. US6,176,882B1, which is a device for adjusting the distance between the vertebral vertebrae. , The upper and lower ends of the spine condyle to be corrected and fixed are stretched a certain distance, so that the spine can be supported and repositioned. Or another Taiwanese patent case No. 098948 "An inte...
