Description

Suction sleeve for surgical smog suction

Technical Field

The utility model relates to the technical field of suction sleeves, in particular to a suction sleeve for surgical smog suction.

Background

The operation smoke is generated by raising the pressure in cells, breaking cell membranes, evaporating the cell body fluid and simultaneously burning and carbonizing tissue protein and other organic matters at high temperature to generate a large amount of smoke and releasing the smoke into the air when electrosurgery equipment, a laser scalpel, an ultrasonic scalpel and the like are applied to perform electrosection, electrocoagulation hemostasis and tissue ablation in the operation process. More than 600 chemical components are contained in the surgical smoke, more than ten chemical components such as polycyclic aromatic hydrocarbon, benzene, methane, formaldehyde, CO, hydrogen cyanide and the like are measured at present, wherein aromatic compounds are the cause of bad smell of the surgical smoke. The carcinogenic effects of polycyclic aromatic hydrocarbons have been studied extensively, and one study estimates that medical personnel are at 117 times the risk of cancer at the end of 70 years of exposure to polycyclic aromatic compounds in smoke as compared to exposure to safe levels. With the rapid development of modern medical technology, electrosurgery equipment and technology have been widely used in the surgical field, and the large amount of smoke generated has caused a serious pollution to the air in the surgical environment, studies have shown that the smoke generated in an orthopaedic surgery operating room a day is a hazard of 27-30 cigarettes, and although there are many existing smoke evacuation devices, practical application difficulties, such as noise, distraction and limited space, and lack of understanding of the hazard of surgical smoke, have made these devices unusable by many surgeons.

The existing suction sleeve pipe only has a suction hole at the front end, the smoke is difficult to be quickly sucked even if the suction force of the central negative pressure is opened to the maximum value after the strong smoke is generated, and the central negative pressure often causes the blocking phenomenon due to various reasons, so that the smoke is dispersed into the air. Based on this, the utility model designs a suction cannula for surgical smoke suction to solve the above problems.
