Anterior cervical flexible eccentric minimally invasive channel system

Abstract

The invention relates to the field of medical instruments, in particular to an anterior cervical flexible eccentric minimally invasive channel system. A semi-ring-shaped esophagus protection drag hook of the system is integrally formed by a semi-ring section, an arc-shaped transition section and a horizontal extension section, the length of the semi-ring section is 50 mm, the bottom of the semi-ring section is upwards warped outwards by 2 mm to form a drag hook, the two sides of the semi-ring section are cylinders with the diameter being 1.5 mm, and the length of the horizontal extension section is 100 mm; the height of the flexible expandable sheet is 20mm, the two sides of the flexible expandable sheet are symmetrical rigid structures of 6mm, the middle of the flexible expandable sheet is an elastic protection pad edge joint of 10mm, and the flexible expandable sheet is used for protecting outside blood vessels and nerves and can be pressed downwards to facilitate operation in a window; and the edge is semicircular, the inner diameter of the edge is 1.6 mm, the edge is used for being inserted into an esophagus retractor cylinder, and a locking screw hole is formed in the edge and used for locking after distraction. When being applied, the system is advantageous in that the surgical wound is small, the recovery is fast, the precise and minimally invasive anterior cervical surgery is really realized, and the requirements of the CADF gold standard of the anterior cervical surgery are met.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an anterior cervical flexible eccentric minimally invasive channel system. Background technique [0002] Cervical endoscopic surgery has a history of more than 20 years so far. In 1989, Tajima first reported percutaneous cervical discectomy. In 1993, Gastambide reported image-guided central partial discectomy. After that, Algara. .Bonati.Sieber.Hellinger, etc. have successively reported laser-assisted surgical treatment of cervical disc herniation. Aweife1's research report in 1994 clearly pointed out that holmium laser is the safest and most effective for soft tissue ablation, which can minimize the thermal damage of surrounding soft tissue. As an alternative technology to laser, the research on soft tissue ablation with high frequency and low temperature radiofrequency around 2000, its excellent performance in hemostasis, contraction or ablation of soft tissue in cervical en...

AI Technical Summary

Problems solved by technology

[0008] It can be seen that at present, there are puncture difficulties in the process of anterior cervical surgery. The rigid expansion channel is not suitable for the anterior cervical spine, and it is easy to damage the cervical tissue structure. Open surgery has large damage and many complications. To solve the clinical effect of lesion clearance fusion stabilization
