Abstract

The invention discloses a patella replacement integrated drilling device and belongs to the technical field of medical instruments, the patella replacement integrated drilling device comprises a guider, a holding rod, a drilling assembly and a power connecting rod, the holding rod is arranged on the guider and fixedly connected with the guider, the drilling assembly is arranged on the guider and rotationally matched with the guider, and the power connecting rod is detachably connected with the drilling assembly. According to the patella replacement integrated drilling device, a first gear drives three second gears to rotate, and the three second gears drive three drilling heads to rotate, so that the patella is drilled and does not need to be drilled for three times, and drilling is faster and more stable.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an integrated drilling device for patella replacement. Background technique [0002] With the advent of my country's aging society, the incidence of knee osteoarthritis is increasing year by year, and total knee replacement has become one of the most popular procedures in orthopedic surgery. It is the common pursuit of patients and joint surgeons to restore the function of the knee joint to the greatest extent and realize the forgetting and long-term use of the prosthesis. In many TKAs, patella replacement will be performed. After osteotomy of the valgus part of the patella, osteophyte removal, measurement of the required patella prosthesis model, positioning, drilling, and installation are required. At present, the process of drilling the patella is achieved by using a three-hole locator and drilling three times with a drill. Because the patella is small and difficu...
