METHOD AND DEVICE FOR CONTROLLING AN ELECTROSURGICAL HF APPARATUS AND HF APPARATUS

摘要

A method of controlling an electrosurgical HF apparatus, as well as an HF apparatus, includes an electrosurgical instrument and an HF generator for generating an HF current. The HF generator is in a locked state in which its activation is not possible. An application to be carried out is to be selected prior to a user-side activation of the HF generator, whereby the HF generator is unlocked.

主权项

1. A method of controlling an electrosurgical HF apparatus, said HF apparatus comprising an electrosurgical instrument (1) and an HF generator (2) or a similar electrical current source for generating or providing an HF current,
the HF generator (2) being electrically connected to the electrosurgical instrument (1) to deliver the HF current to the instrument (1) due to a user-side activation, in which method a) the HF generator (2) first is in a locked state in which the HF generator (2) can not be activated by the user, b) starting from step a), an application to be performed with the electrosurgical instrument (1) is obligatorily set by the user, c) the HF generator (2), when step b) has been carried out, automatically changing over to an unlocked state in which the HF generator (2) can be activated by the user, d) the HF generator (2) is activated by the user for carrying out the desired application, e) the HF generator (2) automatically changes over to the locked state after the user-side activation in step d), and f) the HF generator automatically changes over to the locked state if it is not activated during a predefined period of time after a user-side input of an application type.
