Description

Electrotome waste gas suction device

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an electrotome waste gas suction device.

Background

When the electrotome is used for surgical treatment, a large amount of cautery smoke is generated in the process because the electrotome, whether current or heat, used for hemostasis or cutting tissue when contacting body tissue generates a carbonization reaction when the electrotome contacts the tissue, which is visible smoke. The smoke has certain flammability and toxicity, is proved to be harmful to human bodies, and must be removed in time to avoid the situation that a patient is inhaled into the body or is detonated by the oscillating current of the high-frequency electric knife.

In order to effectively suck and remove the smoke, U.S. patent No. US20020103485 discloses an electrotome device with a smoke evacuation blade, wherein the middle of an electrotome of the device is designed to be provided with a hollow channel, and two sides of the hollow electrotome blade are provided with a plurality of perforations communicated with the hollow channel, and when the electrotome performs electrotome electrocoagulation action, smoke generated by current burning can be sucked into the hollow channel through the perforations at the two sides of the electrotome and sucked into a control and smoke collection device at the rear part, so that health of medical personnel and patients is prevented from being harmed. However, the design of the internal channel of the electric knife increases the manufacturing cost of the knife, and when the surgical instruments are disposable, the expensive knife must be sterilized and reused, which makes the technique impractical.

If chinese utility model patent application No. CN201420436659.7 (No. CN204017554U) discloses a smoke collecting device during operation, which comprises a smoke purifier, the smoke purifier is connected with a smoke sucking pipe with adjustable direction and a negative pressure pipe for discharging smoke in the smoke purifier, the end of the smoke sucking pipe is connected with a rubber smoke sucking horn, the end face of the rubber smoke sucking horn is hollow, and the concave is hollow and is communicated with the smoke sucking pipe. Wherein, through adjusting the position of smoke absorption pipeline in the operation, make smoke absorption pipeline's rubber loudspeaker can accurate suitable aim at smog and produce the position, then inhale smoke purifier with smoke purifier's negative pressure pipeline to can avoid setting up the inconvenience that smoke absorption device and bring on experimental scalpel. However, although the smoke suction pipeline of the smoke collection device in the operation in the patent can be adjusted in a bending way, the height position of the smoke suction port of the smoke collection device in the patent is limited, so that the smoke collection device cannot be conveniently matched with the position of smoke generated in the operation process; secondly, because the flue gas is directly contacted with the inner wall of the smoke absorbing pipeline in the discharging process, the process of disinfecting and cleaning the smoke absorbing pipeline is extremely inconvenient.

Therefore, the existing electrotome waste gas suction device needs to be further improved.
