Abstract
A device (10) for tissue coagulation, in particular for fusion, encompasses an electric source (18), which is connected or which can be connected to electrodes (12, 13) for influencing biological tissue (11) with current. A control unit (22) controls the source (18) during phases I and II of the tissue fusion. These phases I and II correspond to operating phases I, II and III of the device (10). During operating phase I, a monitoring unit (23) determines the energy E1, which is applied into the tissue (11). In the subsequent operating phases II and III, the control unit (22) controls the source (18) by means of the determined energy E1. Such a device turns out to be particularly reliable and to be robust in use.
Claims20
A device (10) for tissue coagulation, the device comprising:
- an electric source (18), configured to be connected to electrodes (12, 13) for influencing biological tissue (11) with current,
- a monitoring unit (23), which is connected to the source (18), configured to determine one or both of a current (IACT) output by the source (18) and a voltage (UACT) is output by the source (18),
- a control unit (22), which includes the monitoring unit (23) and which is connected to the source (18) in a controlling manner, the control unit (22) configured to:
- establish an energy (E1) the source (18) outputs to the electrodes (12, 13) in a first operating phase (I), and
- control the source (18) as a function of the energy (E1), which is determined in the first operating phase (I), in a subsequent second operating phase (II).
A method for applying energy to coagulate tissue, the method comprising:
- contacting biological tissue with electrodes;
- determining an energy (El) to output to the electrodes from a source in a first operating phase (I);
- applying the energy (El) to the biological tissue through the electrodes;
- controlling application of energy by the source through the electrodes in a second operating phase (II) after the first operating phase (I) as a function of the energy (E1) applied in the first operating phase (I).
