ARTIFICIAL SPINAL DISC REPLACEMENT SYSTEM AND METHOD

摘要

An artificial spinal disc implant system for intervertebral disc replacement (0810) is disclosed which is formed from an upper (0801) and lower (0802) bracket which mate to upper and lower spinal vertebrae via upper (0831) and lower (0832) vertebral contact surfaces on the upper (0801) and lower (0802) brackets. The upper (0801) and lower (0802) brackets are joined together via springs (0811) connected to the upper bracket (0801) which rest in spring guide tracks (0812) on the lower bracket. The springs (0811) are connected to the upper bracket (0801) via the use of spring fasteners (0821, 0822) . The upper (0801) and lower (0802) brackets may be installed in sections (0851, 0861, 0871, 0852, 0862, 0872) using laparoscopic surgical techniques and are attached to upper/lower spinal vertebrae respectively via adhesive means applied using injection holes/ports (0841, 0842) in the upper (0801) and lower (0802) brackets respectively.
