Abstract

The invention discloses a lining prosthesis picking and mounting device and method, and solves the technical problems that the existing structural design is unreasonable, the limbs of a doctor are in direct contact with the wound of a patient and a prosthesis due to manual operation of the doctor in the prosthesis mounting operation process, the operation time of the mounting process is long, and the postoperative infection risk is high. The device comprises a handle, an outer sleeve rod and a suction cup device, and the handle and the outer sleeve rod are each of a hollow rod-shaped structure and communicate to form a first cavity; a movable rod is further connected to the interior of the first cavity, and the movable rod is movably and fixedly connected to the interior of the cavity; the suction cup device is fixedly connected to the front end of the outer sleeve rod, and air holes are formed in the side wall of the suction cup connecting part. An inner rod piston ball is arranged at the front end of the movable rod and can penetrate into the second cavity of the suction cup connecting part, the suction cup is controlled to be in a vacuum state or a vacuum releasing state by controlling the movable rod to move front and back in the cavity and controlling the inner rod piston ball to move front and back, and the the device can be widely applied to the technical field of medical instruments.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device and method for picking and installing a lining prosthesis. Background technique [0002] At present, with the development of the national economy and the improvement of people's ideas, the growth rate of the number of people undergoing artificial joint replacement in my country will be faster and faster, and the number of joint replacement cases in my country will gradually increase in the future. The hip joint is the joint that connects the femur bone and the hip bone of the pelvis of the human body, and is the joint that plays the most important role in human walking. When the hip joint is damaged due to factors such as disease or trauma, in order to make it heal, artificial hip replacement surgery is performed to remove the lesion, relieve pain, and restore joint mobility and original functions. [0003] The hip joint prosthesis includes an acetab...
