Abstract

This specification describes technologies relating to an intervertebral disc prosthesis used to strengthen and stabilize the spine. Implementations of the technology described herein comprise a surgical device that is implanted through a small surgical incision into a portion of a human intervertebral disc, various support tools used to insert such a surgical device, and a method by which the device is used to strengthen and stabilize the spine.

Description

technical field [0001] The present invention relates to surgical implant devices, and more particularly to intervertebral disc prostheses. Background technique [0002] The human spine is an important part of human physiology, housing and protecting the spinal cord and providing structural support to the body. In the average human body, the spine consists of twenty-four articulated and nine fused vertebrae, and is usually divided into several regions, including the cervical, thoracic, sacral, and coccygeal regions. [0003] Although there are variations between each vertebra according to its location and region, vertebrae generally include the vertebral body, pedicles, lamina, spinous processes, transverse processes, articular surfaces, and spinal canal, each of which provides It plays an important role in the overall support and protection function of the body. Of these features, the vertebral bodies are particularly important in providing support. The vertebral body is ...
