Abstract

The invention discloses a head presser for orthopaedic surgery, comprising a base device, a press-in device and a lining device. A lead screw of the press-in device is in threaded connection with a lead screw nut of the base device, so that the press-in device can move up and down. The lower end of the lead screw is provided with a lining, the lining device is arranged above the base and under thepress-in device, a test head is placed on the lining device, and the press-in device is moved down to press the test head into the lining. The screw rod and the lead screw nut, substituting for a threaded rod and an internal thread hole, generate little friction resistance, which makes the thread rotation more smoothly, thereby effectively avoiding stuck and saving time and labor.
