Electrosurgery smoke suction apparatus

An electrosurgical apparatus comprising:

• a main body formed with a suction passage therein;
• an extension member including an extension tube coupled to a side of the main body and formed therein with an induction passage communicating with the suction passage, and a sliding tube configured to slide along the extension tube while being inserted in the extension tube, wherein an open front end of the sliding tube has an inclined shape such that the open front end protrudes to be gradually away from the main body from a bottom of the open front end to a top of the open front end;
• and a blade having a first side that protrudes outside through the inclined shape of the open front end of the sliding tube, and a second side that is electrically connected to the main body to receive high frequencies from the main body, wherein an entire length of the extension member is adjusted according to a position of the sliding tube sliding along the extension tube, wherein the extension tube includes:
• a sliding guide part formed in a tubular shape;
• an insertion guide part formed integrally protruding from a rear end of the sliding guide part facing the main body to be coupled to the main body;
• the induction passage formed through the sliding tube and the insertion guide part;
• and a coupling part configured to allow the blade to be coupled to the sliding guide part or the insertion guide part, wherein the sliding tube includes:
• an insertion part configured to slide while being inserted into the sliding guide part;
• and a grip part integrally provided at a front end of the insertion part, wherein an open front end of the grip part is provided with a suction guider that corresponds to the open front end of the sliding tube, wherein the sliding guide part is provided an inner circumferential surface thereof with a guide rail concavely formed along a longitudinal direction of the sliding guide part, with the guide rail provided with a through-coupling portion at an end thereof disposed opposite to the main body to be exposed to an outside, wherein the insertion part is provided an outer circumferential surface thereof with a guide protrusion to slide along the guide rail, and wherein, when the insertion part is inserted into the sliding guide part, the guide protrusion is inserted into the guide rail through the through-coupling portion.

An electrosurgical apparatus comprising:

• a main body formed with a suction passage therein;
• an extension member including an extension guide tube coupled to a side of the main body and formed therein with an induction passage communicating with the suction passage, a sliding part configured to slide along the extension guide tube, and a suction guider coupled to a front end of the sliding part that does not face the main body, wherein an open front end of the suction guider has an inclined shape such that the open front end protrudes to be gradually away from the main body from a bottom of the suction guider to a top of the suction guider;
• and a blade locked to an inside of the extension guide tube, and having a first side that protrudes outside through the inclined shape of the open front end of the suction guider, and a second side that is connected to the main body to receive high frequencies from the main body, wherein an open rear end of the suction guider is coupled to the front end of the sliding part, wherein the extension guide tube includes an extension part formed in a tubular shape with the induction passage formed therein, a coupling part protruding from a rear end of the extension part facing the main body so as to be coupled with the main body, and an extension-locking step protruding from an outer circumferential surface of a front end of the extension part disposed opposite to the main body, and wherein the sliding part is formed in a tubular shape having an inner circumferential diameter larger than an outer circumferential diameter of the extension-locking step, and includes a sliding-locking step protruding toward an outer circumferential surface of the extension part along an inner circumferential surface of a rear end of the sliding part disposed at a position facing the main body.
