Control laws for pneumatic cylinder in order to emulate the Loss Of Resistance principle

Abstract : Medicine requires advanced teaching methods in order to reach an efficient student training without having to train them directly on patients. In France, the Haute Autorité de la Santé (H.A.S.) has stated to "never [do] the first time with a patient" as a requirement for the training of new doctors. The goal of this work is to other a novel robotic solution to teach students how to perform an epidural anaesthesia. This medical operation can be divided intotwo different gestures: First the insertion of a needle between two vertebrae and second the application of pressure on the plunger all along the insertion of the needle. This works aims at simulating this second part as it has already been done on the first part in previous studies. We introduce a way to emulate the principle of loss of resistance felt by the anaesthetist when the needle reaches the appropriate depth.
