Problems solved by technology

[0002] As China enters the age of aging, knee replacement has become a routine orthopedic operation. The most important and complicated step in knee replacement is multiple osteotomies according to the template. The power of the electric pendulum saw for osteotomy is strong. The slag and blood will splash everywhere, which will not only pollute the aseptic area of ​​the operation, lead to postoperative prosthesis infection, bring disastrous complications to doctors and patients, and it is difficult to clean up, and once the bone slag and blood splash into the surgeon's eyes It will seriously threaten the health of the surgeon and affect the progress of the entire operation.

Abstract

The invention relates to a bone residue splashing preventive device for knee osteotomy. Repeated osteotomy according to a mold plate is the most important and complicated procedure in knee replacement, an electric osteotomy swing saw is high in power, and accordingly bone residues and blood can splash all around in an osteotomy procedure, stain an aseptic operating zone, cannot be cleaned easily and occasionally can splash into eyes of surgeons. The bone residue splashing preventive device for knee osteotomy comprises a shield and a movable cover plate; the shield is an elliptical shield made of transparent materials, an opening is arranged on the upper side of the shield, two through holes are arranged on two sides of the shield, and a flexible edge and straps are arranged at the edge of the shield; and the movable cover plate is a hard arc-shaped plate made of transparent materials, an operating opening is arranged on the upper side of the movable cover plate, and the movable cover plate is arranged on the opening in a sliding fit manner, can slide and can completely cover the opening. The bone residue splashing preventive device has the advantages that the bone residue splashing preventive device is simple in structure and convenient to use, is environment-friendly and pollution-free and is particularly suitable for knee osteotomy in various general hospitals or special orthopedic hospitals, and the problem of splashing of bone residues and blood in a knee osteotomy procedure is effectively solved.
