Description

Technical Field

[0001] The utility model relates to the field of orthopedic surgery medical instruments, in particular to a vibration-absorbing and stable osteotomy knife for orthopedic surgery. Background Art

[0002] An osteotomy is a surgical tool used to cut and scrape bone during surgery. It is usually made of stainless steel or other sturdy materials, with a sharp blade and a sturdy handle. The blade design of the osteotomy allows it to easily cut and scrape bone, and is used to remove bone or correct bone deformities during orthopedic surgery. During surgery, the doctor will use an osteotomy to precisely cut and correct bones to ensure the success of the operation and the patient's recovery. An osteotomy is a professional medical tool that should only be used by professionally trained medical professionals.

[0003] Traditional osteotomies are one-piece and made of metal, mostly stainless steel and carbon steel. If the blade is damaged, the entire osteotomy knife will be scrapped and needs to be replaced, resulting in a waste of resources. During orthopedic surgery, medical staff hold the handle of the osteotomy knife to contact the bone. During the process, human bone tissue collides and cuts with the blade. When encountering harder bone tissue during cutting, it will cause setbacks and vibration caused by the knife being stuck, and the vibration will be transmitted to the medical staff's hands through the osteotomy knife. Especially in long orthopedic surgeries, long periods of cutting make the medical staff's hands tired, affecting the reduction of hand accuracy, and affecting the stability and comfort during the operation, which has a certain impact on both patients and medical staff. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is that the traditional osteotomy knife is one-piece and made of metal, mostly made of stainless steel and carbon steel. If the blade head is damaged, the osteotomy knife as a whole will be scrapped and needs to be replaced, resulting in a waste of resources. In addition, when human bone tissue collides and cuts with the blade head, it will cause setbacks and knife jams when encountering harder bone tissue during cutting, and vibration will be transmitted to the hands of medical staff through the osteotomy knife. Especially in long orthopedic operations, long-term cutting makes the hands of medical staff tired, affecting the reduction of hand accuracy, and affecting the stability and comfort during the operation, which has a certain impact on both patients and medical staff.
