Problems solved by technology

[0002] At present, electrosurgical equipment ESU, laser knife, high-frequency scalpel and other tools are widely used in open surgery. During the operation, the tissue is destroyed, ablated and decomposed, causing its fine particles to be suspended in the air, resulting in harmful smoke, ultrafine Harmful particles and odors, etc.; in response to this situation, the usual method is to move the hand-held straw to the surgical site for repeated suction during the operation, which only slightly improves the operating environment; however, the above-mentioned treatment methods cannot meet the actual Surgical needs, low adsorption efficiency, poor adsorption effect

Abstract

The invention discloses a negative pressure suction front end and a negative pressure suction system. The negative pressure suction front end comprises a suction tank, wherein the suction tank is of an annular structure; a suction inlet is arranged in the side, facing an area surrounded by the annular structure, of the suction tank; an exhaust port, by which a negative pressure source gets communicated, is additionally arranged in the suction tank; the negative pressure suction system comprises the negative pressure suction front end and a negative pressure suction device, wherein the negativepressure suction device comprises a device housing, a negative pressure generating device which is arranged in the device housing and an adsorption box; and the adsorption box gets communicated withthe exhaust port in the negative pressure suction front end via a connecting tube. The negative pressure suction front end and the negative pressure suction system provided by the invention can be applied to the technical field of negative pressure equipment; with the application of the invention, shortcomings in the prior art can be overcome; harmful smoke as well as superfine harmful particles and smell, which are generated in an operating process, can be instantaneously sucked away; therefore, relatively high adsorption efficiency is achieved and a relatively good adsorption effect is realized.

Description

technical field [0001] The present application relates to but not limited to negative pressure equipment, especially a negative pressure suction front end and a negative pressure suction system. Background technique [0002] At present, electrosurgical equipment ESU, laser knife, high-frequency scalpel and other tools are widely used in open surgery. During the operation, the tissue is destroyed, ablated and decomposed, causing its fine particles to be suspended in the air, resulting in harmful smoke, ultrafine Harmful particles and odors, etc.; in response to this situation, the usual method is to move the hand-held straw to the surgical site for repeated suction during the operation, which only slightly improves the operating environment; however, the above-mentioned treatment methods cannot meet the actual Surgical needs, the adsorption efficiency is low, and the adsorption effect is poor. Contents of the invention [0003] The technical problem solved by this applicat...
