Description
Technical Field
The invention relates to a connecting device, relates to a connecting interface of a medical instrument, and particularly relates to a quick-mounting locking device.
Background
Surgical robots are now increasingly used in clinical surgery to assist physicians in performing complex surgery. For example, a surgical robot may accurately correlate image data of a patient with the patient's physiological anatomy, assist a physician in performing surgical planning, and may guide the physician in the operation of surgical instruments or may independently perform certain surgical operations. The surgical robot can complete or assist in completing surgical operations, and a surgical navigation system is of great importance. The tool position of the surgical robot can be positioned in real time through the surgical navigation system, and positioning deviation caused by anatomical displacement of a patient can be corrected through real-time navigation. Current surgical navigation systems typically provide a tracer on the front end of the robotic arm or on the surgical tool in order to track and locate the surgical tool.
All instruments in the operating room must be sterilized before use. Surgical tools are typically made of metal and are sterilized by autoclaving. However, tracers, especially optical tracers, are generally not amenable to high temperature sterilization. Therefore, prior to autoclaving, the tracers need to be removed from the tool end for separate sterilization and reinstalled on the tool prior to surgery.
Therefore, there is a need for a quick-mount interface that enables quick installation and removal of the tracer.
