Abstract

The invention provides an acetabulum implanting device with an adjustable anteversion angle and abduction angle. The acetabulum implanting device comprises an implanting rod, wherein a first guide rodand a second guide rod are hinged on the implanting rod; a first fastening unit is arranged on the first guide rod and can fix the first guide rod and the driving rod; and a second fastening unit isarranged on the second guide rod and can fix the second guide rod and the implanting rod. According to the invention, different abduction angles and anteversion angles can be simultaneously adjusted;the accuracy of prosthesis implantation is achieved; meanwhile, the number of fluoroscopy times in an operation can be reduced; the time of the operation can be shortened; the occurrence rate of postoperative complications can be reduced; and more benefits are brought to a patient. The invention also discloses an application method for the acetabulum implanting device. Through the acetabulum implanting device which can adjust different abduction angles and anteversion angles, the accuracy of prosthesis implantation is achieved; meanwhile, the number of fluoroscopy times in the operation can bereduced; the time of the operation can be shortened; the occurrence rate of postoperative complications can be reduced; and more benefits are brought to the patient.

Description

technical field [0001] The invention belongs to the technical field of orthopedic medical devices, and relates to an acetabular driving device with adjustable anteversion and abduction angles, and a method for using the acetabular driving device with adjustable anteversion and abduction angles. Background technique [0002] At present, the natural environment is changeable, social factors are complex, and many factors can lead to femoral head necrosis. With the improvement of clinical examination techniques, more femoral head necrosis was detected, showing younger and more complex. At the same time, modern humans have higher and higher requirements for the quality of life. Therefore, in the field of joint surgery, a large number of patients with femoral head necrosis, hip osteoarthritis or hip dysplasia need to undergo artificial total hip replacement surgery to achieve improvement. The purpose of improving joint function and improving the quality of life. [0003] There a...
