Embodiment Construction

[0014] Such as figure 1 , figure 2 As shown, the bipolar high-frequency line plug 24 is inserted in the elongated flat hole 5a below the slide block 5, and the platform 25a on the plug body 25 controls the depth at which the plug body 25 enters the elongated flat hole 5a. Insert the cylindrical straight rod 18 at the rear of the bipolar electrode 14 guide tube 17 through the round rubber sleeve 13 mounted on the joint 12 into the plug body 25; the insertion rod 21 on the working electrode 15 in the bipolar electrode 14 and the circuit The tail portion 20 of the electrode 16 is respectively in contact with the working conductive post 26 and the return conductive post 27 installed in the plug body 25 to form the working electrode 15 path and the return electrode 16 path. Lock the plunger 21 on the working electrode 15 with the locking wheel 8 on the metal guide post 6 contained in the slide block 5 to prevent the bipolar electrode 14 from moving when it works. The guide tube ...

Abstract

The present invention relates to a bipolar electrode and its connection structure. It is a bipolar operation electrode matched with electroresectoscope for use. Said invention mainly is used for resecting body of gland due to hyperplasia of prostate, tumor of bladder and submucosal myoma of uterus, etc. Said bipolar electrode self-body not noly has a working electrode, but also has a loop electrode, and said current is not passed through the human body, so that it can prevent the burn phenomenon which can be produced when the monopolar electrode current is passed through negative electrode plate of human body and its contact is poor. Said bipolar electrode uses physiological saline as buffer solution, so that it can prevent TURP syndrome which is easily produced by adopting monopolar electrode. The operation method of said bipolar electrode is identical to that of monopolar electrode, and its connection is convenient, and safe and reliable.

Description

technical field [0001] The invention relates to a medical device, in particular to a bipolar surgical electrode used in conjunction with a resectoscope, also known as a resectoscope. Background technique [0002] Resectoscope is a surgical instrument in minimally invasive treatment, mainly composed of inner and outer sheaths, electrodes, manipulators and endoscopes. The electrodes are installed on the slider of the manipulator, and the electrodes are moved back and forth by pushing the slider on the manipulator, so as to perform surgical operations. Resectoscope is used together with high-frequency generator, also known as high-frequency electric knife, and is widely used in urology, gynecology and other departments. It is mainly used for transurethral resection of prostatic hyperplasia glands and bladder tumors; in gynecology, it is used for resection of uterine submucosal fibroids, endometrium and other diseases. Transurethral resection of the prostate (TURP) is currentl...
