Plasma electrode for bladder cancer tumor resection operation

Abstract

The invention discloses a plasma electrode for a bladder cancer tumor resection operation. The plasma electrode comprises an electrode cutter head and an electrode rod, wherein the electrode rod comprises two or more tubular electrode units which are in contact connection; an electrode extension part is arranged at one end, close to the electrode cutter head, of each tubular electrode unit; and meanwhile, one of the ends of the plurality of electrode extension parts is converged at the electrode cutter head and is welded with the electrode cutter head to form a reinforcing part, and the other one of the ends of the plurality of electrode extension parts is connected with an electrode host through a lead respectively. According to the plasma electrode for the bladder cancer tumor resection operation, the strength of the electrode cutter head is enhanced, and the contact area between the electrode cutter head and a bladder tumor during the operation is increased, so that the turnover use area in the bladder tumor operation is increased, the hemostatic efficacy is obtained, the bladder tumor resection efficiency is improved, the service life of the plasma electrode is prolonged, and the practicability of the plasma electrode is improved.

Description

technical field [0001] The invention relates to the technical field of medical plasma surgical instruments, in particular to a plasma electrode for bladder cancer resection surgery. Background technique [0002] 50% of bladder tumors are located on the side wall of the bladder. At present, the obturator nerve reflex of tumors resected on the side wall is very high, as high as 55.3%-100%, which can easily cause bladder perforation, bleeding, pelvic organ damage, tumor cell dissemination, Incomplete tumor resection, etc. Currently, the instruments used for resection have a single function, are not fine enough in structure, and have no separation function, resulting in low resection efficiency. At present, there is no effective method to completely eliminate the obturator nerve reflex during electric resection. Based on this, it is necessary to design A new type of plasma electrode for tumor resection of bladder cancer. [0003] In the prior art, CN212089714U, a protruding pla...

[0005] However, during the use of the needle-shaped electrode, firstly, the needle-shaped electrode has a cylindrical structure, and the plasma cutting layer formed on its side has a small area and relatively weak strength, making it difficult to effectively cut the bladder tumor. Secondly, the needle-shaped electrode has been used for a period of time It is easy to deform and bend after use, and its cutting effect and service life are easily affected
