Abstract

The bloodless liver exsector has one exsector head, one water control button connected through water pipeline to the exsector head, one main control button connected through wires to the exsector head, one power source with circuit board, one suction tube set in the front end of the exsector head, one suction cap covering the front end of the exsector bar and communicated with the suction tube and one flushing tube. During operation, the suction cap with negative pressure sucks out the liquid and other rabbish in the operational view field, and the liver exsector exsects liver tissue while blocking small blood vessels and coagulating electrically for hemostasis. The operation process has clear view field and is safe, and the bloodless liver exsector has compact structure, small size and easy operation.

Description

technical field

[0001] The invention relates to a surgical instrument, in particular to a multifunctional surgical knife for bloodless hepatectomy. Background technique

[0002] Controlling bleeding and exposing various ducts in the liver section during liver resection are crucial technical issues. The liver tissue is covered with a large number of reticular blood vessels and bile ducts. If instruments can be used to close the thin ducts and expose the thicker ducts for ligation, the problem of liver resection will be easily solved. Although the clamping method of the main instruments currently used can clamp thicker channels, it can cause massive bleeding in small blood vessels; high-frequency electrocautery can generate eschar to seal thinner channels through electrocoagulation, but it cannot expose the liver. When a large blood vessel is encountered and the wall of the vessel is damaged by electrocoagulation, a large amount of bleeding will be caused. In addition, the es...
