Abstract

The invention relates to a tibia osteotomy guider. The tibia osteotomy guider comprises an ankle holding device, an adjusting mechanism installed on the ankle holding device and a guider connected with the adjusting mechanism; and a transverse guiding assembly and a vertical guiding assembly are arranged at the top of the guider. According to the tibia osteotomy guider, when the tibia osteotomy guider conducts transverse osteotomy along a tibia spine, the transverse guiding assembly can be used for conducting transverse guiding on a saw blade to conduct osteotomy, the vertical guiding assembly can be used for conducting vertical guiding on the saw blade to conduct osteotomy when vertical osteotomy is conducted, and therefore, the accuracy of the osteotomy is guaranteed, and an operation operator can perform an operation conveniently.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a tibial osteotomy guide in unicompartmental surgery. Background technique [0002] The tibial osteotomy guide for unicompartmental surgery is an instrument for solving tibial osteotomy in unicompartmental knee surgery and is used for knee meniscus replacement surgery. The knee tibial osteotomy guide is a necessary instrument in the operation of the knee joint. Through the tibial osteotomy guide, it is used in conjunction with the surgical power saw blade and fixed by positioning nails. The saw blade can be inserted into the osteotomy guide before osteotomy In the groove, confirm the osteotomy path, and then confirm the actual bone volume of the osteotomy. After confirming that there is no problem, perform a vertical osteotomy along the tibial spine, and then perform a horizontal osteotomy along the guide knife groove to complete the tibial osteotomy. . [000...
