Method for Positioning Endoscope and Auxiliary Positioning Device for Same Method

摘要

A method for positioning an endoscope involves installing an auxiliary positioning device on a robot arm, coinciding a terminal of a docking member of the auxiliary positioning device with a remote center of motion defined by the robot arm, inserting and fixing the endoscope inside the auxiliary positioning device, removing the docking member of the auxiliary positioning device so that a terminal of the endoscope coincides with the remote center of motion of the robot arm, and then inserting the endoscope into a body cavity catheter for finalizing positioning. Thereby, the method helps to save time used for preoperative preparation and provides more precise positioning, without using any additional positioning tools to approach the body cavity, thereby reducing the risk of infection.

1. A method for positioning an endoscope, the method comprising the following steps:
a) installing a robot arm, wherein the robot arm defines a remote center of motion; b) preparing an auxiliary positioning device, wherein the auxiliary positioning device has a fastener, a docking member detachably connected to the fastener, and an apparatus-receiving hole passing through the fastener and the docking member, and installing the fastener of the auxiliary positioning device onto the robot arm, so that a terminal of the docking member of the auxiliary positioning device coincides with the remote center of motion of the robot arm; c) inserting an endoscope into the apparatus-receiving hole of the auxiliary positioning device, so that a terminal of the endoscope is aligned with the terminal of the docking member of the auxiliary positioning device; d) removing the docking member of the auxiliary positioning device, so that the terminal of the endoscope coincide with the remote center of motion of the robot arm; and e) inserting the endoscope into a catheter that gas been inserted in a body cavity.
