    摘要: A two-part NMS-test bench is provided with which instruments, generator voltages, and surgery modes can be evaluated with regard to neuromuscular stimulations. By separating the NMS-test bench in a first part for application of the instrument and in the second part for evaluation of the physiological effect on nerves, a measurement free of artifacts is possible. The spatial and timely separation of the RF-application from the recording of the compound action potentials makes RF-disturbances ineffective. The electrical signals gained in the instrument test chamber can be pre-processed. The recorded electrical signals emitted from the instrument can be evaluated at the nerve model an arbitrary number of times. The variance involved with the recording of compound action potentials during direct use of the instrument can thus be minimized. The separated test of the signals at the nerve model avoids thermal damage of a prepared nerve and falsification of measurement results.

    摘要: Devices and methods for image-based treatment with an instrument configured to apply variable amounts of treatment medium at different locations. Devices having an image caption device that is configured to capture the area to be treated. The device comprises an evaluation device that is configured to determine a treatment trace of the treatment medium relative to the area to be treated from data of the image capture device and to determine a spatially resolved dosage for the area to be treated based on the treatment trace. Devices having a representation device that is configured to display the treatment trace and/or the spatially resolved dosage optically for a user, relative to the tissue. Methods to optically indicate the locations of the area to be treated of the tissue surface that have already been treated and/or the dosage with which the respective treated locations have been treated.

    摘要: A surgical device having an apparatus with a generator and an instrument supplied by a generator. A sensor is part of the device that is attached to the patient, for example to an extremity thereof, during surgery to detect the movement of the patient. The sensor is connected with a control device that modifies the operation of generator and particularly switches the generator off, if the sensor detects a movement of the patient exceeding a threshold. Injuries of patient that could occur by involuntary twitches during surgery process are thus avoided.
