Abstract

The invention discloses a selectable bone joint forming device for clinic patients. The device comprises a selection adjustment device and a bone joint model, wherein a control box is arranged on the selection adjustment device, through holes are formed in two sides of the control box, sliding support strips are arranged in the through holes, teeth are formed in one end of each sliding support strip, a motor is arranged in the control box, the left and right structures of the bone joint model are controlled through first electric telescopic rods so as to adjust the left and right sizes of the bone joint model, the upper and lower thicknesses of the bone joint forming device are controlled through second electric telescopic rods to better facilitate adjustment, and the motor drives the sliding support strips to control the front and rear lengths of the bone joint model. A Bluetooth device is arranged on the selectable bone joint forming device and can be used for remote control, the selectable bone joint forming device for the clinic patients is simple in structure and can change the shape of implanted bone, and accordingly, the bone can be better matched.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone arthroplasty device that can be selected by clinical patients. Background technique [0002] There are various types of cartilage such as hyaline cartilage and fibrocartilage. Hyaline cartilage is found, for example, on the articular surfaces of bones in joints, and is responsible for providing the smooth, glide movement of movable joints. Often, severe damage and loss of cartilage is achieved by using, for example, silicone (eg, for cosmetic repairs) or metal alloys. Treated by replacing the joint with prosthetic material, arthroplasty is highly invasive and requires surgical removal of all or a substantial portion of the articular surface of one or more bones. During these procedures, the medullary canal space is usually enlarged to fit the stem of the prosthesis, and the number of possible replacements is limited. It will be appreciated that arthroplasty is hi...
