PURPOSE: To achieve optimal cutting and emulsification with minimal fluid, by providing a housing connectable to a gas source, and a booster mechanism which converts a low-pressure fluid supplied through a fluid inlet into a high- pressure fluid output at a distal end of a cannula. CONSTITUTION: The surgical tool has a handpiece 21 to be manipulated by a hand, and a cannula 22 extending from the handpiece 21 spouts high-pressure pulse jet for surgical cutting and tissue emulsification. The cannula 22 is connected to an aspirator 23, to form vacuum to remove fluid introduced by the surgical tool, body fluid and emulsified tissue. The handpieces 21 is connected to a low-pressure fluid supply part 24 to provide fluid for high-pressure fluid pulses for cutting, while a low-pressure gas supply part 26 is connected to the handpiece 21 to power the handpiece 21 to generate high-pressure fluid pulses. This sufgical tool causes surgical cutting and excision action for surgeons for therapeutic purposes. |
