Dual-action rotational and linear actuating mechanism

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 said resector-loop adjacent to a body portion to be treated in a sequence of rotational and linear maneuvers;
• said 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 said effecter.
