Abstract

The invention discloses an electric knife with negative pressure suction. The main point of the technical solution is to include an air pump for providing negative pressure. The air pump is connected with a suction tube for guiding airflow. The front end of the suction tube is provided with a suction head for suctioning smoke. A connecting head is arranged on the pipe body of the suction pipe, and a connecting seat is also arranged on the handle body of the electric knife handle. The present invention has the following beneficial effects: after use, the medical personnel press the button with their hands, one end of the button passes through the through hole, and extends into the card slot, and the second inclined surface presses the card joint, driving the card joint to leave the card slot, and the medical staff Pull the clamping plate out of the clamping hole, so that the connector is separated from the connection seat, so as to facilitate cleaning and maintenance and ensure the cleaning effect.

Description

technical field [0001] The invention relates to an electric knife, more specifically, it relates to a negative pressure suction electric knife. Background technique [0002] An electrotome is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue when the high-frequency and high-voltage current generated by the effective electrode tip contacts the body, and realizes the separation and coagulation of the body tissue, thereby achieving the purpose of cutting and hemostasis. [0003] When the electric knife is cutting, the electric knife will burn and burn the human tissue, resulting in smoke. In order to avoid the smoke from affecting the sight, the smoke can be sucked by installing a negative pressure suction device. However, the negative pressure suction device is fixed on the electric knife, which is inconvenient for cleaning and maintenance. Contents of the invention [0004] Aiming at the deficiencies in the prior art,...
