Monopolar RF Liver Knife

Abstract

The invention discloses a mono-polar radio frequency liver resection knife comprising a mono-polar knife head, a knife head handle, a knife bar and an ablation tube apparatus. The knife bar is provided with an electrocoagulation operation switch and an electroresection operation switch. The mono-polar knife head is connected with a first circuit board and a mono-polar power line respectively through the electrocoagulation operation switch and the electroresection operation switch through leads. The knife bar is of a hollow structure. The leads, the first circuit board and a second circuit board are arranged in the hollow structure. One end of the ablation tube apparatus is fixed to the knife head handle, and the other end of the ablation tube apparatus is fixedly connected with the mono-polar knife head via a fixing part. Ablation tubes are communicated with a radio frequency power supply through connecting leads and the second circuit board. During an operation process, haemostasis, resection and blunt dissection of liver tissues can be performed via the mono-polar knife head, the liver tissues are coagulated by the ablation tubes to occlude small vessels and bile ducts, so that the operation is convenient and safe, and easy to operate.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a monopolar radio frequency liver cutter. Background technique [0002] Liver resection is a common procedure in surgery today. Because the liver has a rich blood supply and is densely covered with small blood vessels, bleeding is the most common complication of liver resection. How to effectively reduce intraoperative bleeding has become the focus of liver surgery. The liver is a solid organ, and liver lesions are often located in the deep part of the liver, and often grow in a spherical shape. In order to minimize the resection of the normal liver, the operation needs to be resected along the periphery of the lesion. The operation is difficult, and there is no simple treatment for the appeal. Program. SUMMARY OF THE INVENTION [0003] In order to overcome the above problems, the present invention provides a monopolar radiofrequency hepatectomy knife, which can effectively improve th...
