combined osteotomy guide

Abstract

The invention discloses a combined osteotomy guide. A plurality of guide units are arranged corresponding to a surgical part of a bone; the guide units are provided with guide slots for insertion of a bone cutting instrument; a positioning device for fixing the guide to the bone is arranged; the guide units are separately manufactured or manufactured in an integrated way; each guide unit is provided with a combination device; two adjacent guide units are combined through combination devices; a combination relationship is designed according to an operation plan for the bone; each guide unit is provided with a connecting device; after the guide units are combined, the guide units are fixedly connected through connecting devices. The combined osteotomy guide can be used for bone cutting and bone setting, is not required to be detached in the process, the bone joining angle is accurate, the height accords with a design plan, overdependence on personal capability of a doctor is avoided, and the surgical speed and quality are obviously improved.

Description

technical field [0001] The invention relates to a combined osteotomy operation guide plate, in particular to a guide plate used when operating or correcting deformed parts of human bones. Osteotomy and osteosynthesis can be performed through the guide plate, which belongs to the field of surgical instruments. Background technique [0002] Human bones have the ability to grow adaptively. Human bones with normal shape and structure ensure the appearance and actions of the human body, but diseases or accidents often cause distortions of human bones, such as the bending of the human tibia, such as figure 1 As shown, it directly causes the patient to have difficulty walking and standing. In the existing orthopedic medical methods, osteotomy can be performed on the deformed bone for correction and treatment. Excess bone tissue can be removed, and a piece of prosthesis can also be cut off to fill the bone. The final result is to make the bone length and The shape meets the predete...

AI Technical Summary

Problems solved by technology

[0006] Since the bones are spliced ​​after cutting, although the cutting surface can be pre-designed, and the cutting position and cutting length on the bone can be guaranteed by using the osteotomy guide plate, the formed cutting surface is only a plane, and the bone itself Irregularities lead to the lack of reliable reference during the splicing process, and the bones after splicing are prone to misalignment and angle errors at the splicing site, such as Image 6 shown

Since this type of operation is mainly performed on the basis of the doctor's experience and relies heavily on the doctor's personal ability, the effect of the operation is not ideal and the reliability is low. Inexperienced doctors need long-term study and practice to perform the operation, which is very difficult. It is difficult to achieve theoretical accuracy, and there is a deviation from the original design. The impact of this deviation on the patient may not be obvious, but it may also be serious. In the end, the operation fails. If the patient is re-operated, it will bring harm to the patient. subsequent injury and suffering
