Abstract

The invention provides an acetabular cup driving device and a joint replacement device. The acetabular cup driving device comprises a striking barrel, a driving rod, a plurality of clamping arms, a movable rod and a guide assembly, wherein the striking barrel is provided with through first end and second end; the driving rod rotatablely extends into the first end; the plurality of clamping arms are distributed on the periphery of the second end and all extend in a direction, far away from the first end, of the second end; and various clamping arms all are hinged with the striking barrel. The movable rod is provided with a driving end and an abutting end, wherein the driving end movably extends into the second end and is in threaded connection with the driving rod; and the movable rod is connected with the striking barrel through the guide assembly to be guided to move along an axial direction. The plurality of clamping arms are arranged around the abutting end. The movable rod can be driven to move away from the first end along the axial direction of the striking barrel through rotating the driving rod to abut against various clamping arms through the abutting end, so that the clamping arms rotate outwards. According to the acetabular cup driving device, an acetabular cup can be more conveniently fixed in a driving device.

Description

technical field [0001] The disclosure relates to the technical field of medical devices, in particular to an acetabular cup driving device and a joint replacement device. Background technique [0002] In joint replacement surgery, it is necessary to fix the acetabular cup and the acetabular cup driving device, and then apply an impact load to the acetabular cup through the acetabular cup driving device to drive the acetabular cup into a predetermined position. [0003] In order to fix the acetabular cup to the acetabular cup driving device, a threaded hole is often provided at the bottom of the acetabular cup, and the acetabular cup driving device is threadedly connected to the threaded hole. However, the threaded hole is easily damaged, making it difficult to fix the acetabular cup to the acetabular cup driving device. In addition, after the cup is driven into the predetermined position, the cup liner needs to be driven into the cup. Wherein, debris generated during the i...
