METHOD AND SYSTEM FOR AUTOMATICALLY SELECTING AND CONTACTING AN EMERGENCY CONTACT PERSON BASED ON LOCATION

摘要

A surgical instrument (10, 110, 210, 310) that is disposed for performing water jet surgical operations comprises a nozzle 18 that can be moved by means of a hydraulic actuator (23) out of a retracted or passive position into a moved forward or active position. The actuation is accomplished by means of a hydraulic fluid that is supplied to the instrument head (11) via a tube (20) and/or a hose (43). The fluid, e.g., a sodium chloride solution, that is to be injected into the tissue can be used as the hydraulic fluid that is supplied to the nozzle (18). Preferably, HF current can additionally be applied to the nozzle (18). Said HF current can be conducted to the nozzle via a line (30) extending through the fluid conducting element (15) or via the electrolyte present th
