Abstract:
A multi-function high-frequency tool for an endoscope, comprising an insert portion and a handle portion, the insert portion comprising an insulating tip, a first electrode having a needle-knife function, a second electrode having an IT-knife function, and a spray head; the handle portion comprising a first slider, a connector, an injection connector, and a second slider. The second electrode has a hollow structure, and the first electrode extends through the second electrode; the proximal end of the first electrode is fixedly connected by means of a mandrel connecting member to the distal end of a mandrel; the proximal end of the mandrel is connected to the first slider of the handle portion, and moves axially on the handle portion by means of the first slider, thereby causing the first electrode to expose from/retract into the second electrode.

Claim (Index 1):
A multi-function high-frequency tool for an endoscope, comprising an insert portion and a handle portion, wherein the insert portion comprises an insulating tip, a first electrode having a needle-knife function, a second electrode having an IT-knife function, and a spray head; the handle portion comprises a first slider, a connector, an injection connector, and a second slider;\n the second electrode has a hollow structure, and the first electrode extends through the second electrode; proximal end of the first electrode is fixedly connected by means of a mandrel connecting member to the distal end of a mandrel; the proximal end of the mandrel is connected to the first slider of the handle portion, and moves axially on the handle portion by means of the first slider, thereby actuating the first electrode to expose from and retract into the second electrode; the spray head is fixedly connected by means of a hose connecting member to a hose, and several gaps formed between several troughs and the hose connecting member are provided on the spray head; the hose is coated with an insulating sheath connected to the second slider, and actuates, by means of axial movement of the second slider, the insulating sheath to move axially, thereby causing the second electrode to expose from and retract into the insulating sheath; the injection connector is in communication with the hose to form a liquid channel, and the outer diameter of the mandrel connecting member is larger than the aperture of a hollow portion inside the spray head, so that when the first electrode extends out by a distance, the mandrel connecting member is stopped by the spray head; the proximal end of second electrode is nested inside the hollow portion of the spray head and is fixedly connected to the spray head; the distal end of the second electrode is fixedly mounted inside the insulating tip, so that the second electrode whose distal end is fixedly provided with the insulating tip forms an IT knife comprising an insulating tip; and the first electrode, the second electrode, the mandrel, and the mandrel connecting member are all conductors, and the mandrel is connected to a high-frequency power supply through the connector of the handle portion.
