Bone defect repairing device

Abstract

The invention provides a bone defect repairing device which comprises a bone filling cavity which is hollow and matched with the defected bone in shape. Due to the fact that the bone filling cavity is hollow, autologous, xenogenous or artificial bone blocks, bone particles even bone powder prepared in advance can be filled into the bone filling cavity, the filled bone facilitate later bone cell crawling growing in after initial fixation, normal attachment of soft tissues wrapping outside is achieved, and matching of prosthesis with physiological bones is increased as a whole.

Description

technical field [0001] The invention relates to the field of medical repair prosthesis, in particular, to a bone loss repair device. Background technique [0002] The upper and lower jaws are one of the most complex bones in the whole body. Jaw defect is the most common bone defect disease, which can be caused by a variety of diseases, such as maxillofacial cysts and tumors, acute and chronic osteomyelitis of the jaw, radiation osteonecrosis, severe trauma, infection, and congenital genetic diseases. It leads to the partial or complete resection or loss of the mandible, which interrupts the continuity of the bone structure and is often accompanied by defects of adjacent soft tissues. Mandibular defects seriously affect the physiological functions of patients such as language, breathing, chewing, swallowing and facial beauty, which seriously reduces the quality of life of patients. The repair of jaw defects has always been a highly concerned medical topic. Traditional repa...
