Design of Contact Force for Ultrasonic Scanner

Abstract

The global hospital's capacity can gradually decline, especially after the outbreak of the COVID-19, and thus traditional medical methods can no longer bear a large number of patients. At present, most hospitals rely on doctors and nursing staff to diagnose and treat patients. This not only increases the burden on doctors and nursing staff but also greatly reduces the burden on health care quality. In order to obtain better health care quality, automation is one of the important factors in solving medical quality problems. We are conducting automated introduction research for the ultrasonic scanner. Robotic arms are used to replace doctors for consultations by adding jelly and injection buttons to the robotic arm. In terms of the contact between the end of the robotic arm and the human body, we introduced the force sensor and the depth camera into the robotic arm. With the force sensor and the depth camera feedback data, we perceive the feedback of the ultrasonic scanner and the human body contact force. The results show that our design can greatly increase the amount of hospital’s capacity and reduce the burden on doctors.
