Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field, concretely relates to a single hole thoracoscope monopolar electrotome with auxiliary lung compression device. BACKGROUND

[0002] Thoracoscope sympathicotomy is the only method with lasting curative effect for the treatment of hand perspiration at present. The operation adopts single cavity trachea intubation or laryngeal mask assisted ventilation under general anesthesia. The incision is usually taken in bilateral axillary, and single hole operation is adopted. The ventilation is temporarily stopped before the pleura is incised, and low tidal volume ventilation can be carried out after thoracoscope and electric hook are placed. Under the action of artificial pneumothorax and head high position, lung tissue collapses, and T3 / T4 chest sympathetic nerves are exposed. During the above operation, the sympathetic nerves are often shielded by the lung, and the T4 sympathetic nerves are more difficult to expose due to the lower position, so that it is often necessary to open more operation holes, and special instruments are used to push away the lung tissue and press it down, so as to fully expose the best operation visual field (namely T4 sympathetic nerves). If single hole operation is insisted at this time, it is necessary to wait for the slow collapse of the lung, and the target sympathetic nerves are exposed to carry out the next operation.
