Positioning tool for strephexopodia osteotomy orthopedic surgery

Abstract

The invention provides a positioning tool for strephexopodia osteotomy orthopedic surgery. The positioning tool comprises a positioning cutting block and is characterized in that the positioning cutting block comprises an inner side fixing arm and an outer side fixing arm, wherein the inner side fixing arm comprises a short-distance inner side arm and a long-distance inner side arm, the outer side fixing arm comprises a short-distance outer side arm and a long-distance outer side arm, a short arm cutter groove is formed between the short-distance inner side arm and the short-distance outer side arm, a long arm cutter groove is formed between the long-distance inner side arm and the long-distance outer side arm, the short arm cutter groove and the long arm cutter groove communicate to form a cutting positioning cutter groove, the two ends of the inner side fixing arm and the two ends of the outer side fixing arm are fixedly connected, and positioning holes are formed in the inner side fixing arm and the outer side fixing arm. Cutting of the strephexopodia osteotomy orthopedic surgery can be achieved, the situation that steps are difficult to push and combine due to the fact that the osteotomy face is uneven is avoided, and surgery failures caused by small bone fractures or joint face injuries are avoided.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a positioning tool for valgus valgus osteotomy orthopedic surgery. Background technique [0002] It is often necessary to use a cutting saw or a bone knife to cut the bone at the surgical site during orthopedic surgery. In existing operations, the use of a cutting saw and a bone knife when cutting bones is all based on the doctor's surgical experience. , for inexperienced orthopedic surgeons, it is difficult to grasp the cutting depth and cutting inclination angle, and accidents are prone to occur during the operation. Due to misoperation, damage to the soft tissue, nerves and blood vessels at the surgical site, medical accidents, and uneven osteotomy surface lead to poor movement and alignment of the steps, and sometimes it is easy to cause small bone fractures or damage to the articular surface, resulting in surgical failure.

[0002] It is often necessary to use a cutting saw or a bone knife to cut the bone at the surgical site during orthopedic surgery. In existing operations, the use of a cutting saw and a bone knife when cutting bones is all based on the doctor's surgical experience. , for inexperienced orthopedic surgeons, it is difficult to grasp the cutting depth and cutting inclination angle, and accidents are prone to occur during the operation. Due to misoperation, the soft tissue, nerves and blood vessels of the surgical site are damaged, and medical accidents occur. The uneven osteotomy surface leads to poor movement and alignment of the steps, and sometimes it is easy to cause small bone fractures or damage to the articular surface, resulting in surgical failure.

[0003] In the valgus osteotomy orthopedic operation, it is often necessary to cut the bones of the foot, but because the bones of the foot are often characterized by small size and large quantities, high precision is often required when cutting the bones of the feet. If there is an angle deviation during the cutting, the ideal effect of the operation may not be achieved, and the patient’s condition will not be improved. Therefore, the cutting of the foot bone requires a lot of clinical operation experience and superb skills. The difficulty of bone and bone surgery is increasing, and the operation process of the foot bone is also quite slow. Because the size of the foot bone is too small, common fixing tools cannot be used for fixing on small bones, so there is an urgent need for a foot that can be applied to the foot.
