Plate-shaped bracket for reinforcing bone surface

Abstract

The invention relates to a plate-shaped bracket for reinforcing a bone surface, which belongs to the field of artificial repair of human bones such as alveolar bone, skull, pelvic bone and the like. The bracket is used for covering the bone surface to be reinforced or repaired, and comprises a lath-shaped bracket plate body made of an absorbable material, wherein the bracket plate body comprises amicroporous plate layer for covering a bone surface and a porous plate layer arranged on the microporous plate layer; the porous plate layer is provided with a plurality of macropores through which afixing device passes, and the microporous plate layer is provided with a plurality of micropores capable of blocking cells and allowing nutrient substances to pass; the bracket plate body can be fixed on a bone surface through the positioner; and a bone grafting space filled with bone grafting filler is formed between the bracket plate body and the bone surface. In the scheme, the plate-shaped support does not need to be disassembled through a secondary operation, and pain of a patient is relieved; based on the various structural designs in the scheme, the bracket is suitable for flat bones,long bones, special-shaped bones and the like, and can adapt to different bone surface positions.

Description

technical field [0001] The invention relates to a plate-shaped support for bone surface reinforcement, which belongs to the field of artificial repair of human bones such as alveolar bones, skulls, and pelvic bones. Background technique [0002] When the human body grows with age, human bones tend to be prone to bone cracks or tooth loss. In the cracks of bone cracks or the alveolar bone after tooth loss often occurs due to material exchange between bones and human tissues, but there are bone cracks. Or the alveolar bone is often unable to retain bone elements, resulting in bone atrophy at the position of the fracture or the alveolar bone. The following will take the alveolar bone as an example to explain the causes and effects of bone atrophy. [0003] The alveolar bone, also known as the alveolar process, is the protrusion of the jaw that surrounds the root of the tooth; the socket that accommodates the teeth is called the alveolar fossa, the alveolar bone between two tee...

AI Technical Summary

Problems solved by technology

[0004] When the human body ages and the teeth fall off, the alveolar bone often deforms and atrophies. Dental implants, because, in this case, dental implants will cause secondary damage to the originally atrophied alveolar bone and cause the matrix of the implant to fall off or collapse. Therefore, when the alveolar bone shrinks, it is necessary to repair the tooth The alveolar bone is reconstructed and the alveolar bone is thickened and corrected so that it meets the conditions for dental implants before dental implants can be performed. However, the existing alveolar bone repair technology often uses titanium mesh for fixed repair, and the titanium mesh is often fixed with screws. , and in this way, the removal of the titanium mesh requires a second operation, and the screw tapping and tightening process will cause multiple injuries to the fragile alveolar bone, and the patient will cause secondary injuries

[0005] The market lacks a method of alveolar bone repair that does not require repeated operations and does not cause damage to the original bone surface. How to perform bone surface thickening and repair has become an urgent problem to be solved.
