Description

Surgical electric knife with smoke suction function

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an electric scalpel with a smoke suction function.

Background

The electric knife is widely used in surgical operation, so that the incision and hemostasis of the operation part are more convenient, safe and efficient, but in the operation process, tissues such as fat, protein and the like are incompletely combusted in the electrotomy or electrocoagulation process to generate a large amount of smoke containing tiny particles, and the smoke can not only shield the visual field of an operator and influence the operation, but also can cause harm to the body health of the operator. The generated smoke has bad smell, and particles smaller than 10 microns, especially particles smaller than 2.5 microns (PM2.5) can directly enter bronchus, bronchiole and alveoli, interfere the gas exchange of lung, and cause diseases including asthma, bronchitis, cardiovascular diseases and the like. PM2.5 can also be used as a carrier of viruses, bacteria, medicaments and toxic and harmful substances, and has accumulative damage to the health of exposed people.

In the operation process, an assistant needs to use the suction apparatus to synchronously suck the smoke, but the suction apparatus per se shields the operation field when the traditional suction apparatus sucks the smoke to reduce shielding, and the traditional suction apparatus can collide with and push the operation instruments of an operator, so that the operation space of a doctor is reduced, and the operation progress is influenced.

In order to solve the problem, various improved electric knives with suction devices are provided, but most of the electric knives have complicated structures, poor reliability, complex operation, large volume and poor practicability, are rarely put into production and used in clinical models, are expensive, and increase the operation cost burden of patients. For example:

the Chinese invention patent CN201521014303.5 discloses a manual control integrated electric knife aspirator component, wherein an empty aspiration pipeline is positioned in a metal electric knife head, an opening is arranged at the foremost end of the electric knife head or close to the foremost end, the pore diameter of the pipeline is small, and the pipeline is simultaneously used for aspirating blood and is easily blocked by coagulated blood and tissue residues.

The Chinese patent of invention CN201922342852.X discloses an electric surgical knife pen capable of absorbing smoke, which is complex in structural design and large in volume, a smoke absorbing ring is sleeved on the outer side of an electric knife handle, and an air pump is arranged in the smoke absorbing ring, so that an operator is inconvenient to operate.

Therefore, the technical personnel in the field need to solve the problem that the electric knife with the smoke suction function has simple structure, easy production, effective removal of surgical smoke in the surgical process, complete control by a doctor and no interference to the surgical operation process.
