HF surgical instrument with performance control from the surgical handle

摘要

The main patent... (patent application P 3600990.3) relates to an HF surgical instrument with an HF generator (22), which exhibits an adjustment device (24) for adjusting the HF power (P) delivered, and with a surgical handle (2) connected to the HF generator (22), which handle exhibits an active electrode (4) and at least one switch (6, 8) for switching on and off the HF current flowing from the HF generator (22) to the active electrode (4). At the surgical handle (2) a first and a second control element (16, 18) are then arranged, which through a device (28) are connected with the adjustment device (24) of the HF generator (22) in such a way that actuating the first control element (16) results in an increased delivery of HF power and actuating the second control element (18) results in a reduced delivery of HF power. In order for the operator to be able to control a change in the HF power delivered, without having to lose sight of the field of operation, according to the invention it is provided that upon actuating the first and/or second control element (16, 18) a display signal is triggered simultaneously, which can be detected by the operator. The display signal is preferably visible optically on the surgical handle (2). However, it may also be detectable acoustically, for example by means of a loudspeaker (28) on the surgical instrument.
