Suction unit used in surgery

Abstract

The invention discloses a suction unit used in surgery, which comprises a flow distribution tube, a smoke suction unit and a liquid suction unit. The flow distribution tube comprises a main tube, a first flow distribution branch and a second flow distribution branch, the smoke suction unit comprises a suction tube, the suction tube is communicated with the first flow distribution branch and connected with a skin protecting towel, the liquid suction unit comprises a tubular suction handle, the front end of the tubular suction unit handle is connected with a suction head, and the rear end of the tubular suction handle is communicated with the second flow distribution branch via a flow guiding tube I. The smoke suction unit is arranged at an opening of a surgical cavity, the suction range ofthe suction tube is large, smoke generated during electric scalpel surgery can be thoroughly sucked away, injury to medical staffs due to the smoke is avoided, the skin protecting towel encircles a surgical incision, and tissues of the incision can be prevented from being sucked away by the suction tube; the liquid suction unit can suck away blood, incision irrigation liquid, fester and the like which are generated during the surgery, and is convenient in operation; and the smoke suction unit is integrated with the liquid suction unit, the suction unit is simple in structure, and the quantityof suction equipment required in a surgery process is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a suction device used in operation. Background technique [0002] In surgical operations, in order to improve the operation speed, reduce the patient's pain and economic burden, and reduce the amount of blood loss during the operation, electric knife is often used to cut the tissue and coagulate the bleeding point to stop bleeding. However, in the process of using the electric knife, harmful gas overflow is inevitable; medical personnel exposed to this harmful gas for a long time will inevitably cause serious damage to the body, so it is necessary to use a suction device to suck away the harmful gas during the operation; Bleeding, wound washing, pus, etc. need to be sucked out with a suction device. [0003] At present, the treatment method for the harmful gas produced by the electric knife is: the operator uses an ordinary electric knife with a smoke suction device, but the suction device of...
