Anterior Cervical Spine Adjustable Interface Zero-profile Support Fusion Fixation Titanium Mesh System

Abstract

The invention discloses an adjustable and interface type zero-incisura titanium mesh supporting, fusing and fixing system for the anterior cervical spine and belongs to the field of medical instruments. The system comprises two fusion parts (1) and a supporting part (2), wherein one fusion part (1) is fixedly connected with one end of the supporting part (2), the other fusion part (1) is in threaded connection with the other end of the supporting part (2), at least two interface fusion holes (15) are formed in the outer end surfaces of the two fusion parts (1) respectively, the ports of the interface fusion holes (15) are small, and the inside of the interface fusion holes (15) are large. The system design adopts communication type and interface type double insurance fusion, the length is adjustable, zero incisura locking and fixation are realized, and steel plate fixation is not required.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anterior cervical adjustable interface-type zero-notch support, fusion and fixation titanium mesh system. Background technique [0002] Subtotal cervical spondylectomy was applied clinically in the 1960s, and titanium mesh came out in the 1980s and has been used clinically for nearly 30 years. Traditional bone graft fusion emphasizes "vertebral fusion"—bone is resected from the upper and lower vertebral bodies across the middle However, due to anatomical and physiological reasons, the distance between the upper and lower vertebral bodies is relatively long, and the "crawling replacement healing journey" of the bone after subtotal corpectomy is long and difficult (above 4cm), and the healing time is relatively long. Wearing neck brace brake reaches 3-6 month, can not in time return work position, brings loss to family, society, country. [0003] In addition, the traditional tita...

[0002] Subtotal cervical spondylectomy was applied clinically in the 1960s, and titanium mesh was introduced in the 1980s and has been used clinically for nearly 30 years. Traditional bone graft fusion emphasizes "vertebral fusion"—bone is resected from the upper and lower vertebral bodies across the middle However, due to anatomical and physiological reasons, the distance between the upper and lower vertebral bodies is relatively long, and the "crawling replacement healing journey" of the bone after subtotal corpectomy is long and difficult (above 4cm), and the healing time is long. Wearing a neck brace for 3-6 months, unable to return to work in time, causing losses to the family, society, and the country

[0003] In addition, the traditional titanium mesh has been around for nearly 30 years. It is only used as a bone graft fusion device in cervical subtotal corpectomy surgery. The length cannot be adjusted and needs to be cut, and it needs to be used in conjunction with plate fixation. There are prosthesis subsidence and bone graft non-fusion many other complications
