Device for the intraoperative neuromonitoring of nerves in the pelvic area of a patient

摘要

The invention proposes a device for intraoperative neuromonitoring of nerves in the pelvic area of a patient, with at least one nerve stimulator (16) that can be introduced into the operating area during an operation and with one that can be connected to at least one pelvic organ (14; 15) of the patient (13) Sensor device (20). In order to create a device of this type with which it is possible to reliably check the integrity / functionality of nerves that act on one or more pelvic organs, in particular the bladder and / or the rectum, during an operation in the pelvic area of a patient and to check without any significant delay, the invention proposes that the sensor device (20) have at least two measuring electrodes (23) which can be applied to the pelvic organ (14; 15) and an impedance measuring device (21 ) with a display (22) indicating changes in impedance on the pelvic organ (14; 15) between the measuring electrodes (23). The stimulation of nerves that are connected to a pelvic organ such as the bladder or rectum leads to changes in the complex electrical resistance (impedance) of the organ tissue in question, which can serve as an indicator of the integrity of a nerve stimulated by the nerve stimulator.
