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) andlower (0832) vertebral contact surfaces on the upper (0801) and lower (0802)brackets. The upper (0801) and lower (0802) brackets are joined together viasprings (0811) connected to the upper bracket (0801) which rest in springguide tracks (0812) on the lower bracket. The springs (0811) are connected tothe upper bracket (0801) via the use of spring fasteners (0821, 0822) . Theupper (0801) and lower (0802) brackets may be installed in sections (0851,0861, 0871, 0852, 0862, 0872) using laparoscopic surgical techniques and areattached to upper/lower spinal vertebrae respectively via adhesive meansapplied using injection holes/ports (0841, 0842) in the upper (0801) and lower(0802) brackets respectively.
