Plate-shaped support for strengthening bone surface or bone surface to be repaired

Abstract

The invention relates to a plate-shaped bracket for strengthening a bone surface or a bone surface to be repaired and belongs to the field of artificial repair of human bones such as alveolar bones, skull and pelvis. The plate-shaped bracket is used for covering the bone surface to be strengthened or repaired and comprises a lath-shaped bracket plate body made of an absorbable material, wherein the bracket plate body comprises a microporous plate layer for covering the bone surface and a porous plate layer arranged on the microporous plate layer; a plurality of macropores through which fixing devices penetrate are formed in the porous plate layer, and a plurality of micropores capable of blocking cells and allowing nutrient substances to pass through are formed in the microporous plate layer; the bracket plate body can be fixed onto the bone surface through a positioner; and a bone grafting space for being filled with a bone grafting filler is formed between the bracket plate body and the bone surface. According to the scheme, the plate-shaped bracket does not need to be disassembled through a secondary operation, and suffering of a patient is relieved; and according to the scheme, various structural designs are suitable for circumstances such as the flat bones, the long bones and special-shaped bones, so that different bone surface positions can be adapted.

Description

[0001] This application is a divisional application of an invention patent application titled: A plate-shaped bracket for bone surface reinforcement, with the application date: November 25, 2020, and the application number: 202011335171.1. technical field [0002] The invention relates to a plate-shaped support for strengthening bone surfaces or bone surfaces to be repaired, and belongs to the field of artificial repair of human bones such as alveolar bones, skulls, and pelvic bones. Background technique [0003] 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 t...

Problems solved by technology

[0005] 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

[0006] 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.
