Design of end-effector quick-change device for medical collaborative robots

With the rapid development of medical collaborative robot technology, end-effector with single function has been difficult to meet the needs of clinical surgery. Medical collaborative robots in clinical surgery have caused problems such as increased riskiness of surgery, delayed treatment time, and occupation of healthcare resources because of the narrow operating space, single execution operation, and troublesome replacement of surgical instruments. In this paper, a lightweight, compact and flexible end-tool device is designed so that it has mechanical feedback and temperature feedback and quick-change function. Designing the overall structure of the device and constructing equipment selection and experimental platform, system control used the host computer to write the control program to achieve the end of the actuator of the quick-change function, and analyzed the quick-change module force and strength, and combined with the finite element analysis software ANSYS Workbench on the strength of the key components for the check, to verify the reliability of the structure of the device and the rationality of the device.
