Embodiment

[0051] First, determine the relative positions of the two balloons and the claw cage according to the differences in individual lesions obtained after the examination, and then fix the electrode loops b and c and the two balloons according to the above description. The balloon end of the catheter is in the figure 1 When it is in the retracted state, it can be placed in the reserved passage of the endoscope and enter the cavity along with the endoscope. The other end of the endoscope has a handle for human operation. There are two options for gas injection and liquid injection at the handle end . The endoscope operator probes the endoscope into the cavity and stops when it is about to reach the tumor. At this time, continue to push the handle of the catheter to make the catheter extend out of the front end of the endoscope and continue forward to reach the tumor tissue. Adjust the angle position so that the endoscope is in the position Visualize the position so that the tumor ...

Abstract

The invention relates to a saccule electrode duct for cavity tissue ablation. The saccule electrode duct comprises a duct a and a duct b arranged in the duct a, wherein an electrode sleeve ring a, a saccule b, an electrode sleeve ring b, a potential electrode a, a potential electrode b, an electrode sleeve ring c, a saccule a, and an electrode sleeve ring d are sequentially arranged on the outer surface of the duct a from left to right; a metal claw cage b is arranged between the electrode sleeve ring a and the electrode sleeve ring b; a metal claw cage a is arranged between the electrode sleeve ring c and the electrode sleeve ring d; the electrode sleeve ring b, the electrode sleeve ring c and the duct a are fixedly connected; the electrode sleeve ring a and the electrode sleeve ring d can freely slide in the duct a; the duct b is a flexible hollow columnar pipe body, and 4 conducting wires in spacing spiral wounding are arranged on the outer surface; and the conducting wires are respectively connected with the electrode sleeve ring b, the electrode sleeve ring c, the potential electrode a and the potential electrode b. The invention provides the saccule electrode duct which can perform safe and effective ablation radical cure treatment on malignant tumors.

Description

technical field [0001] The invention relates to the field of medical device equipment, and relates to a cavity discharge device embedded in an endoscope, in particular to a balloon electrode catheter for realizing non-thermal effect ablation of cavity tumors, especially malignant tumors in the bile duct. Background technique [0002] Liver, gallbladder, and pancreas tumors are the most common group of digestive system malignancies, and they are also the most aggressive and heterogeneous group of malignancies. Due to the complex anatomical relationship and important physiological functions of the liver, biliary system, and pancreas, the diagnosis and treatment of hepatobiliary and pancreatic-related diseases have always been the focus and difficulty of research. In terms of anatomical relationship, the intrahepatic capillary bile ducts gradually converge to form the left and right hepatic ducts, and then merge with the cystic duct at the hilum to form the common bile duct.
