TH4672A - Bipolar electrode welding and cutting system (Electrothermal bipolar vessel sealing and cutting system) - Google Patents

Abstract

DC60 The bipolar electro-vascular closure system can close large blood vessels or tissues with blood vessels in it to permanently clog the artery by heat clamping after welding is closed. Tissues next to the seal are welded without Need to use scissors The system consists of a mobile part. And high frequency electric power generator Mobile part used in The separation of the tissue until the desired tissue is obtained. The power source supplies high current, low voltage. To melt the tissue that is clamped between the tweezers Close the weld until the blood cannot pass through the clamping area. Permanently This weld can withstand blood pressure greater than 360 mm Hg and when sliding. Next clamping position in the desired cutting position Then another clamp will be able to release the low-voltage current energy. So high that the tissues are ripe, burned, torn apart Vascular closure and cutting use separate controls. The bipolar electro-vascular closure system can close large blood vessels. Or tissue with blood vessels in it, causing permanent vascular occlusion With thermal clamping After the weld is closed, the tissue next to the weld can be cut without using scissors. The system consists of a mobile part. And high frequency electric power generator The mobile part is used to extract tissue until the desired tissue is obtained. The energy source supplies high-voltage, low-voltage energy to dissipate the tissue clamped between the tweezers. Closed until the blood is permanently unable to pass through the clamping area. The weld can withstand blood pressure greater than 360 mm Hg and when the next clamping position is promoted to the desired cutting position. Then clamping again can release a high-pressure low-current energy until the tissues are ripe, burnt, and torn apart Vascular bonding and cutting use separate controls.
