The Pressure Distribution Test System of Doctors’ Hand in Laparoscopic Surgery

Abstract:

A surface pressure distribution test system of a doctor’s hand during a laparoscopic surgery based on LabVIEW was designed. The principle was that real time acquisition of data signal on multi-channel sensors, and using data acquisition card to get the feed back voltage signal from these pressure sensors, and then transferred to a PC. The test system had realized the real time processing and display of the signal on LabVIEW. The pressure detection range was 0-210g. The system could detect the surface pressure real time of the part of a doctor’s hand which contacting the surface of handle during the laparoscopic surgical procedure. This system could also make quantitative evaluation of the contact pressure on the handle of the laparoscopic instruments and provide a reference to ergonomics design of the handle.
