Intervertebral movable indwelling device and its integrated implanting apparatus and method

Abstract

The invention relates to the technical field of medicines, in particular to an intervertebral movable indwelling device and its integrated implanting apparatus and method. The intervertebral movable indwelling device comprises an upper bone plate, a liner, a vertebral core and a lower bone plate, wherein the liner is embedded in the upper bone plate, the vertebral core is inserted in the lower bone plate, and the liner and the vertebral core form a spherical friction pair in clearance fit. The integrated implanting apparatus comprises a clamp rod, a grip and a knob, wherein a taper joint at the tail of the grip is inserted in a rotary cavity at the end of the knob so that the grip and the knob can rotate freely, and the clamp rod penetrates the inner cavity of the grip and then is connected with internal thread of the knob. By the intervertebral movable indwelling device and its integrated implanting apparatus and method, doctors can complete multi-directional surgical operation without surgical reproduction instruments, and relative motion between the product and the implanting apparatus due to operations such as shifting and adjusting in different directions can be avoided.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an intervertebral motion preservation device, an integrated implantation instrument and an implantation method thereof. Background technique [0002] Intervertebral motion preservation devices currently have Bryan, Prestige product series, ProDisc C, Mobi-C, PCM, SRCURE-C and other products that have been approved by the FDA and are widely used around the world. implanted device products, but there is still room for improvement in some special implanted device products. At present, there is no intervertebral motion-preserving device approved by CFDA in China. Most of the domestic intervertebral motion-preserving devices are in the patent stage, and few of these patented products have targeted design of special implantation devices. [0003] Some clamping instruments adopt the quick-opening clamping method based on the principle of surgical forceps. This type of clamping instrum...

AI Technical Summary

Problems solved by technology

The present invention aims to solve the following problems in the traditional intervertebral motion preservation device implantation device and implantation method: ①The opening distance of the clamping port of the implantation device exceeds the product size range due to the different design of the clamping principle of the traditional intervertebral motion preservation device , which further lead to problems such as a larger surgical operation window, increased surgical difficulty, and longer postoperative healing time; ② Some traditional intervertebral motion preservation device implants have product displacement and loosening during the process of transferring products after product clamping Issues that seriously affect the implantation of the product; ③Some intervertebral motion-preserving device products have implanted devices that are too small in size or inconvenient to grasp and use force, resulting in inconvenience for doctors to use and poor experience.
