Description

Technical Field

[0001] The utility model relates to the technical field of interventional surgery, in particular to an arm fixing device. Background Art

[0002] During percutaneous coronary intervention (PCI), the patient's arm needs to be fixed and the angle between the arm and the body needs to be adjusted to facilitate the procedure. Existing techniques often use bandages to fix the arm, but the tightness of the bandages is difficult to control. Too tight can affect blood flow, while too loose can make the arm unstable. Furthermore, wrapping and removing the bandages is cumbersome, and the arm support plate also needs to be fixed after the angle is adjusted. Currently, this is done by rotating a nut, adding another step to the preparation process. Utility Model Content

A screw 15 is vertically threaded on the fixing frame 13, and a pressure plate 16 is rotatably set at the lower end of the screw 15. The pressure plate 16 is rotated to correspond to the palm of the patient's hand. The screw 15 is rotated to drive the pressure plate 16 to move downward, and the fixing frame 13 is moved. The position of the pressure plate 16 is adjusted by the fixing frame 13, so that the first fixing component 3 can adapt to patients with different arm lengths.

[0030] Two slide grooves 11 are provided on the support plate 2 , and the slide grooves 11 are arranged along the length direction of the support plate 2 . Slide blocks 12 are slidably arranged in the slide grooves 11 , and the two slide blocks 12 are fixed to both sides of the fixing frame 13 respectively.

[0031] The slider 12 is I-shaped and cannot be separated from the slide groove 11. A cushion 14 is provided on the support plate 2, and the cushion 14 corresponds to the pressure plate 16. The cushion 14 is used to support the back of the patient's hand.
