Electric knife handle capable of attracting electric knife

Abstract

The invention discloses a lighting electric knife handle, and an electric knife handle, a negative-pressure suction tube and a negative-pressure pump which are used to attract the electric knife. A power supply circuit of the electric knife is arranged in the wall of the hollow electric knife handle or inside the hollow electric knife handle, and a suction port is arranged at the rear end of the electric knife handle. A conductive hollow tube is provided with a hollow channel, and the rear end of the conductive hollow tube is arranged inside the front part of the electric knife handle. The rear end of the conductive hollow tube is connected with the power supply circuit of the electric knife and the front end of the conductive hollow tube stretches out of the electric knife handle. The front end of the conductive hollow tube develops forwards to a thin pointed suction port. The invention provides the electric knife which can absorb all the smog generated during an operation, and as for the operation at a narrow and deep area, the electric knife can go in depth to absorb the smog generated during the operation and the liquid impurities beside the electric knife in time and discharge the smog and the liquid impurities to an outdoor place or into a sterilizer, which can not cause the blockage of the negative-pressure suction tube and the negative-pressure pump. As for the narrow dark area of the operation area, a lighting lamp on the electric knife can conveniently and clearly irradiate. The electric knife head, the electric knife handle, the negative-pressure pump can be conveniently and quickly dismantled, replaced and disinfected, and meanwhile, a filter screen and a filter can be conveniently replaced.

Description

technical field [0001] The present invention relates to a medical device, furthermore, it relates to an electric knife handle with lighting function, an electric knife handle for attracting the electric knife, a suction catheter and a negative pressure pump. Background technique [0002] Now, the electric knife is very frequently used in medical treatment. When the electric knife cuts tissue or electrocoagulates hemostasis, it will produce a lot of poisonous and pungent fumes. If you work in this environment for a long time, you will inhale a large amount of this poisonous gas, which will undoubtedly endanger your health. The physical and mental health of medical staff and patients will affect the vision of the operator, which will easily lead to the failure of the operation; when working, the liquid next to the electric knife will affect the normal operation of the electric knife; some electric knife is equipped with a suction device, and the additional smoking nozzle is thi...

Problems solved by technology

[0002] Now, the electric knife is very frequently used in medical treatment. When the electric knife cuts tissue or electrocoagulates hemostasis, it will produce a lot of poisonous and pungent fumes. If you work in this environment for a long time, you will inhale a large amount of this poisonous gas, which will undoubtedly endanger your health. The physical and mental health of medical staff and patients will affect the vision of the operator, which will easily lead to the failure of the operation; when working, the liquid next to the electric knife will affect the normal operation of the electric knife; some electric knife is equipped with a suction device, and the additional smoking nozzle is thick Bulky, easy to affect the operator's sight, and because the mouth of the smoking pipe is far away from the electric knife head, the mouth of the smoking pipe cannot be close to smoking in a narrow area, and all the smoke cannot be sucked. The smoke drawn by the traditional suction device is then discharged into the room. Causes a pungent smell in the room as usual

Because there is no filter device in the suction tube of the electric knife with suction function, it is easy to cause suction blockage, which affects the speed and efficiency of suction, and has a negative impact on the operation; the electric knife head, electric knife handle, and negative pressure suction tube cannot be pulled apart for disinfection, which is easy Cause disinfection dead corners, deposits and carbon deposits in the smoking pipe, etc., which are inconvenient to be cleaned in time; the smoke cannot be discharged to the outside in time and thoroughly; for narrow and dark areas, the operating light cannot be illuminated, and the operator of the electrosurgical knife cannot see the operating area clearly
