Application Number: JP,2024-204726
Category (FI): A61B18/12
Stage: PROBLEM TO BE SOLVED: To provide a control console and a method for supplying a drive signal to a surgical instrument.SOLUTION: A control console 22 includes a transformer 90 having a primary coil 84 and a secondary coil 88. The primary coil receives an input signal from a power source 82 and induces a drive signal in the secondary coil so as to supply the drive signal 105 to a surgical instrument 28. A first current source having a leakage control coil 92 is connected to a route of the drive signal. The primary coil induces a first cancellation current to be injected inside the route of the drive signal so as to cancel a leakage current in the leakage control coil. A sensor 108 connected to the route of the drive signal outputs a detection signal 110 so as to provide feedback on the leakage current. The sensor can be connected to a second leakage current cancellation source and/or a disorder detection stage. The power source can be made variable, and can feed a current to a second current source as well.SELECTED DRAWING: Figure 4 (Grant)
