Tibia osteotomy cutting apparatus

Abstract

The invention discloses tibia osteotomy cutting apparatus. The apparatus comprises a first knife rest, a blocking base and a stop pin, wherein the first knife rest is mounted outside the body of a patient, and is provided with a knife groove for guiding a knife to cut a tibia from the side surface of the tibia along the guiding direction of the knife groove, the blocking base is installed at one end of the first knife rest and located on the front face of the tibia, the blocking base is provided with guide holes in a penetrating manner, the axis of each guide hole, and an advancing path, guided by the knife groove, of the knife are located on the same plane, and the stop pin penetrates into the tibia from the front surface of the tibia along one guide hole of the blocking base and is transversely arranged on the cutting path of the knife.

Description

technical field [0001] The invention relates to a tibial osteotomy cutting device, in particular to a safe osteotomy cutting device capable of limiting the cutting depth. Background technique [0002] At present, High tibial Osteotomy, H.T.O., which is used to eliminate knee joint degenerative lesions, is to perform an oblique osteotomy on the tibia, and adjust the position of the tibial plateau through the opening angle of the tibial osteotomy to make correction After the gravity of the patient, it can be moved to the ideal position on the tibial platform, reducing the wear of the original damaged end cartilage and reducing the pain of the patient. [0003] When the traditional high tibial osteotomy correction operation is performed, the doctor directly cuts the patient's tibia with the knife according to the experience and the guidance of the X-ray detector. Since the knife does not have any guiding device during cutting, the cutting The angle of osteotomy is very prone t...

Problems solved by technology

[0003] When the traditional high tibial osteotomy correction operation is performed, the doctor directly cuts the patient's tibia with the knife according to the experience and the guidance of the X-ray detector. Since the knife does not have any guiding device during cutting, the cutting The angle of osteotomy is very prone to a large number of errors. In addition, when cutting the tibia, the cutting depth of the tool often depends only on the scale on the knife. However, the scale is often blocked by blood or muscle tissue during cutting, which is not easy. Clear identification, therefore, in order to accurately perform high tibial osteotomy correction surgery, it is necessary to rely on the doctor's rich surgical experience, and it is obviously necessary to improve
