Problems solved by technology

However, it is difficult to accurately align the mechanical arm with the position of the poking card during passive positioning, so that the poking card and the mechanical arm enter the same axis. Every time the poking card and the mechanical arm are locked, they will be disassembled and adjusted again. The adjustment process Moderate risk of secondary trauma to the patient's abdominal wall wound, serious may tear the wound, threatening the patient's life

Abstract

The invention provides a positioning device and a positioning method for a mechanical arm of a surgical robot, which belong to the technical field of medical devices, wherein the positioning method for the mechanical arm of a surgical robot includes: swinging the mechanical arm, making the auxiliary arm connected to the poking holder of the mechanical arm The center of the bottom of the positioning unit coincides with the center of the surface of the patient's operating hole, so that the mechanical arm remains at this position; the auxiliary positioning unit is removed, and the surgical stamp inserted into the patient's operating hole is connected to the center of the patient's operating hole. connected to the poke card holder described above. The positioning device and positioning method of the mechanical arm of the surgical robot of the present invention can avoid the risk of secondary trauma to the abdominal wall wound of the patient during the process of adjusting the mechanical arm, and realize the rapid connection between the mechanical arm and the surgical poking card, which greatly shortens the preparation before surgery Time spent working.

Description

technical field [0001] The invention relates to a medical device, in particular to a positioning method and a positioning device for a mechanical arm of a surgical robot. Background technique [0002] Laparoscopic surgical robots have been widely used in minimally invasive abdominal surgery. Laparoscopic surgical robots usually use three or four mechanical arms instead of human arms to complete more complex operations. During the operation, usually a few small holes are made in the abdominal wall of the patient, and then the poking card is inserted into the human body through the small holes, then the mechanical arm is placed in a suitable position, and the poking card is set on different mechanical arms, so as to realize the poking card Follow-up with the mechanical arm. However, it is difficult to accurately align the mechanical arm with the position of the poking card during passive positioning, so that the poking card and the mechanical arm enter the same axis. Every ti...
