Embodiment Construction

[0070] figure 1 A living body extraction surgery system (hereinafter, simply referred to as a surgery system) 101 including a later-described endoscopic treatment instrument according to the first embodiment of the present invention is shown.

[0071] For example, in a heart bypass operation, a blood vessel of a subject is used as a heart bypass blood vessel. The blood vessel is, for example, a blood vessel to be extracted for cardiac bypass, that is, a great saphenous vein (hereinafter also simply referred to as a blood vessel) formed from the thigh of the lower limb to the ankle, or an upper limb artery such as the radial artery. This blood vessel is extracted over the entire length using an endoscopic treatment tool or the like.

[0072] like figure 1 As shown, the surgical system 101 includes a trocar 21, a dissecting tool 31 as a device for excision of a living body, a tool for cutting a living body, that is, a collector 41 as an endoscope treatment tool, and a rigid ...

Abstract

An endoscopic surgical instrument (41) includes an insertion section (42) which is inserted into a body cavity, and a surgical section (43) which is disposed on a tip end of the insertion section (42) and treats an object. The surgical section (43) includes a body section (431), and a first electrode (433), a second electrode (435), and a third electrode (437) which are disposed on the body section (431). The surgical section (43) coagulates and cuts the object by using a combination of not less than two of the first electrode (433), the second electrode (435), and the third electrode (437).

Description

technical field [0001] The present invention relates to an endoscope treatment tool for treating a subject such as a blood vessel. Background technique [0002] In recent years, in cardiovascular bypass surgery, blood vessels such as lower limb blood vessels such as the patient's own great saphenous vein or upper limb arteries such as the radial artery are sometimes used as bypass blood vessels. In order to extract the blood vessel under endoscopic observation, a living body extraction surgery system is used. [0003] This living body extraction surgery system includes an endoscope treatment tool for treating a subject (living tissue) such as a blood vessel, and an endoscope inserted into the endoscope treatment tool. [0004] A harvester as an endoscopic treatment instrument is an instrument having a bipolar cutter for electrically cauterizing and cutting side branches of blood vessels. [0005] A groove and a pair of electrodes arranged to sandwich the groove in the vert...
