Can also be minimized. This eliminates the need for patients to stay long after surgery and allows them to return home on the day of surgery.
- the endoscope inserted into the current-carrying device is protruded from the current-carrying device so that the current-carrying device portion does not enter the field of view, and the affected part is observed in a wide field of view while visually recognizing on the display device. This makes it easy to search for the nerve bundle, and once the target nerve bundle is in the field of view, gradually move the endoscope into the current-carrying instrument without removing it from the field of view.
- the position of the endoscope is finely adjusted and focused so that both the nerve bundle and the electrodes of the current-carrying instrument are in the visual field of the endoscope.
- a search is then performed to identify the nerve fibers to be blocked. That is, as described above, the electrode is brought close to a specific nerve fiber, the voltage is adjusted by the controller, and a weak current is applied to the electrode to stimulate the nerve. While observing the response of each part of the body at that time, electrical stimulation to the nerves is repeated sequentially, and the target nerve fibers are specified. Once the nerve has been identified, the controller can then use a controller to increase the current to block the target nerve.
- the needle-shaped electrode can stimulate a specific nerve fiber in the nerve bundle with a weak current, and by examining the responses of various parts of the body to the stimulation, the target nerve fiber can be identified, It can block only the nerves that do. Examples of cases where such nerve fiber blockade is effective include, for example, hyperhidrosis, Reino's syndrome, and reflex sympathetic atrophy (RSD).
