However, these studies only used the self-healing function of dynamic gel, and ignored its special shock-absorbing and energy-absorbing effect; and the introduced special functional groups, although they can improve the properties of materials, have no way to really enter the market because Its catabolic safety cannot be assessed

Abstract

The invention belongs to the field of biological materials, and particularly relates to an injectable gel material for spinal repair. Single-arm PEG is dissolved in deionized water, and barium sulfateis added and dispersed to obtain a PEG aqueous solution; HAuCl4 is added into the deionized water to prepare a gold-containing aqueous solution; finally the PEG aqueous solution and the gold-containing aqueous solution are mixed according to a ratio to obtain dynamic hydrogel. Based on the dynamic covalent chemical reaction method and by utilizing the conventional and safe raw materials, the dynamic gel with acceptable strength and biological compatibility is prepared.

Description

technical field [0001] The invention belongs to the field of biological materials, and in particular relates to an injectable gel material for spinal repair, in particular to a PEG hydrogel material prepared by dynamic covalent chemical reaction. Background technique [0002] Lumbar degeneration refers to a joint lesion in which articular cartilage degenerates, followed by proliferative new formation of joint margins and subchondral bone. Labor, exercise or bad living habits lead to an increasing number of patients who need to repair the degenerated position of the lumbar intervertebral disc in the spine. It is conservatively estimated that more than 85% of the population will experience mild back pain, and 40% of these patients show lumbar degenerative disease. Change. Disc repair or reconstruction alone costs more than $200 billion a year in the United States, ranging from steroids to physical therapy to invasive foraminotomy or fusion. Surgical treatment of lumbar degen...
