FEEDBACK DEPENDENT LITHOTRIPSY ENERGY DELIVERY

摘要

PROBLEM TO BE SOLVED: To provide a lithotripter including a lithotripsy apparatus for treatment of a urinary tract stone by fragmentation.SOLUTION: A lithotripsy apparatus 10 includes a lithotripsy wave guide shaft 22 configured to transmit an energy form to at least one urinary tract stone. A lithotripter includes a sensing device configured to provide signal data for determining optimal application of energy during treatment with the lithotripsy apparatus. The lithotripter includes a processor configured to collect the signal data and provide feedback to a user. The processor has a control logic configured to determine at least one of: a) if the lithotripsy wave guide shaft is in contact with a tissue; b) if the lithotripsy wave guide shaft is in contact with the stone; c) type of the stone; d) if the user is applying force in excess of a predetermined threshold; and e) physical characteristics of the stone.SELECTED DRAWING: Figure 1A
