Cervical vertebra pyramid microfrauma fusion apparatus

Abstract

A microwound fusion device used between servical pyramids is a barrel body made of memory NiTi alloy, which has many holes, an open slot, several barrier bosses at its one end, and an end cover at its another end. After it is shrunk at low temp, an endoscope is used to put it in the gap between two servical pyramides. After its temp is restored, it can restore to original size.

Description

1. Technical field [0001] The invention relates to a device for fusion and fixation of human cervical vertebrae in surgical operations, in particular to a cervical vertebral intervertebral body which can be implanted through an anterior endoscope for minimally invasive implantation of anterior cervical intervertebral body fusion. Minimally Invasive Fusion. 2. Background technology [0002] Most of the vertebral segments of cervical spondylosis are in an unstable state. In this case, performing osteotomy and decompression on the anterior column and middle column of the vertebral segment will aggravate the loosening and instability of the vertebral segment. Therefore, after cervical decompression, it is required that the vertebral segments be stable and not displaced in the shortest possible time, so fusion surgery is very important. There are many methods of anterior fusion in the past, but there are inaccurate fusion, collapse, pseudarthrosis formation or plate loosening, s...
