Moldable individual spine fusion device

Abstract

The invention relates to a moldable individual spine fusion device which comprises an upper top plate, a lower top plate, a molding spring, an inner biological silica gel ring, an outer biological silica gel ring, buckles A and buckles B. The upper top plate and the lower top plate are connected together through the molding spring, the inner biological silica gel ring and the outer biological silica gel ring are distributed on the inner side and the outer side of the molding spring and connected to the upper top plate and the lower top plate through the buckles A and the buckles B, and a bone cement injection hole is formed in the outer biological silica gel ring. The moldable individual spine fusion device can be self-adaptively adjusted according to practical physiological characteristics, such as the height (the distance), the angle and the gradient, between fusion centrums of a patient, and the moldable individual spine fusion device can be perfectly attached to the upper centrums and the lower centrums; bone cement is injected into the position between inner biological silica gel and outer biological silica gel, and due to the characteristics of the bone cement, the moldable individual spine fusion device can be rapidly solidified and molded to achieve the good supporting function; sclerotin is injected into an inner cavity of the moldable individual spine fusion device through a hole in the upper top plate, synostosis of the centrums is prompted, and the moldable individual spine fusion device is convenient to implant and has the good market prospects.

Description

technical field [0001] The invention relates to a shapeable individualized spinal fusion device, which belongs to the technical field of medical devices. Background technique [0002] As the central axis skeleton of the human body, the spine is the pillar of the body and has functions such as weight bearing, shock absorption, and movement. With the modernization process of our country's society and the trend of aging, spine-related diseases are becoming more and more prominent. As an important technique in spinal surgery, vertebral body / intervertebral fusion has been widely used in the treatment of spinal fractures, dislocations, deformities, tumors, etc., and has played an irreplaceable role in the treatment of degenerative spinal diseases. At present, most of the fusion cages used in vertebral body / intervertebral fusion are made of titanium alloy or polyether ether ketone material, and the external structure of the fusion cage can stretch the vertebral body to restore the...

AI Technical Summary

Problems solved by technology

To select the most suitable specifications according to the different conditions of patients, this requires that a set of fusion devices of all specifications must be prepared for selection before the operation, and continuous testing and adjustments are required during the operation. Mismatching problems caused by sub-fraction, resulting in implant loosening, vertebral fusion insufficiency, serious may lead to surgical failure
