Embodiment Construction

[0025] Below in conjunction with accompanying drawing, invention is described in further detail.

[0026] combine Figure 1-2 According to one aspect of the present invention, an osteotomy sight is provided, which is characterized in that it includes a handle 1, a knife holder 3, an adjustment member 4 and a fixed shaft 2, the fixed shaft 2 is arranged on the handle 1, and the axis position of the handle 1 A first through hole 11 is provided, and the knife cover 3 is connected with the adjustment member 4 through the first through hole 11 .

[0027] Therefore, in order to accurately point to the center of the femoral head during tibial vertical osteotomy during unicompartmental replacement, the present invention provides an osteotomy aimer. Using the relationship between the femoral intramedullary positioning rod, the femoral drilling guide and the inherent 7° valgus angle of the hinge device in the Oxford unicompartmental manipulation tool, insert the fixed shaft 2 on the os...

Abstract

The invention discloses a bone-cutting aiming instrument. The bone-cutting aiming instrument comprises a handle, a knife pouch, an adjusting part and a fixed shaft, the fixed shaft is arranged on thehandle, a first through hole is formed in the axis of the handle, and the knife pouch penetrates through the first through hole and is in cooperative connection with the adjusting part. The inventionfurther discloses a using method of the bone-cutting aiming instrument. The aim is to research influences of the bone-cutting aiming instrument on knee joint inner side unicompartmental knee arthroplasty, and therefore the effective method which is used for reducing malposition and related complications of tibia prostheses in the unicompartmental knee arthroplasty is studied. With the bone-cuttingaiming instrument, perpendicular bone cutting of the inner side tibial plateau can be made to be simpler and more accurate, repeatability is high, especially for beginners just developing the arthroplasty, a learning curve can be shortened, the arthroplasty is easily further popularized, rehabilitation can be accelerated for a patient, time in a hospital can be shortened, and the hospitalizationexpenses can be reduced for the patient.

Description

technical field [0001] The invention relates to the field of medical operation aids, in particular to an osteotomy aimer and a method for using the osteotomy aimer. Background technique [0002] It has been more than 60 years since McKeever first proposed the concept of UKA in the 1950s and gradually promoted it to clinical use. This system is specially used for the treatment of osteoarthritis in the anteromedial compartment of the knee joint, with definite curative effect. Following the Oxford III unicondylar knee system in 1990, a new generation of Microplasty unicondylar knee system (MP) came out in 2009, and MP began clinical application in 2012. MP simplifies the operation technique, especially the positioning of the femoral prosthesis has been greatly improved. The intramedullary positioning rod and the femoral drilling guide are connected through the hinge device, and the flexion, extension and rotation positions of the femoral prosthesis are precisely positioned, av...
