Abdominal electrocoagulation smoke removal device based on Bernoulli principle

Abstract

The invention relates to the technical field of medical apparatus and instruments, and discloses an abdominal electrocoagulation smoke removal device based on the Bernoulli principle. The abdominal electrocoagulation smoke removal device comprises an insulation pipe body; a thin smoke suction port and a thick smoke suction port are formed in a surrounding mode at the lower position of the insulation pipe body; the inside of the middle part of the insulation pipe body is connected with a filtering sleeve; an opening is formed at one side of the filtering sleeve; the middle part of the insulation pipe body is connected with a spiral shell; the lower part of the insulation pipe body is connected with a cleaning device; the lower end of the cleaning device is connected with a cleaning head; the inside of the upper end of the cleaning device is connected with a spiral fan blade; and the lower end of a conducting rod is connected with an electrocoagulation head. By the thin smoke suction port formed outside the thick smoke suction port, a diameter of the thin smoke suction port is smaller than that of the thick smoke suction port, eschar generated by electrocoagulation moves to the thinsmoke suction port and the thick smoke suction port, a flow rate of the thin smoke suction port is relatively high, the eschar can be absorbed at the opening of the thin smoke suction port, and such structure ensures a continuous smoke removing effect of the thick smoke suction port so as to avoid a problem that a smoke extraction gas hole is liable to block.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electrocoagulation smoke removal device for abdominal cavity based on Bernoulli's principle. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body. Electrocoagulation hemostasis devices are commonly used in medical devices. Electrocoagulation hemostasis refers to the use of High-frequency current coagulates small blood vessels to stop bleeding, and electric heat coagulates and carbonizes the blood. The commonly used electrocautery devices include high-frequency electric knife and argon electric knife. The methods of hemostasis include unipolar electrocoagulation and bipolar electrocoagulation. When hemostasis, the electrocautery device can directly cauterize the bleeding point, or use the h...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an electrocoagulation device for removing smoke from the abdominal cavity based on the Bernoulli principle, which has the advantages of efficiently removing smoke and preventing blockage of the smoke removal holes, and solves the problem of the existing electrocoagulation device for the abdominal cavity. Efficient smoke removal is poor and the smoke vents are easy to block
