| 摘要 |
The present invention provides a dual action linear-rotational resectoscope comprising: (a) a resection loop and loop shaft which are raised to high electrical tension for either resection or cauterisation; (b) an endoscope tube electrically insulated from the loop shaft; (c) an insulating sheath comprising an inner and outer sheath between which fluid is free to flow, surrounding both the loop shaft and the endoscope tube; (d) a handle by which an operator controls both linear and rotational motion of the resector-loop such that the operator performs a resection by using either rotational motion of the resector-loop, linear motion of the resector-loop or any combination of the two; and, (e) a dual-action actuating mechanism useful for manoeuvring the resector-loop adjacent to a body portion to be treated in a sequence of rotational and linear maneuvers; the maneuvers are selected from a group consisting of linear motion followed by rotational motion, rotational motion followed by linear motion, only rotational motion and only linear motion; comprising a unified actuating module in communication with the effecter.
