Abstract
The utility model discloses a kind of resectoscope plasma bipolar electrode, comprise working electrode, described working electrode is U-shaped, described working electrode is arranged with several beckets.This utility model is by increasing becket on the working electrode (s, during work, high-frequency energy conducts to becket by working electrode, when working electrode slides in focus, becket can roll at affected area, thus realizes the cutting of lesion tissue and melt, this mode is compared with traditional working electrode, significantly can not only reduce the injury of normal tissue and the risk of secondary damage, and can not increase the difficulty of operation, medical personnel's operation is more convenient.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of resectoscope plasma bipolar electrode.
Background technology
Urethral stricture, prostatic hyperplasia are clinical common diseases, conventional operative treatment at present, traditional open surgery is very large to normal urethra physiological structure damage, patient is difficult to the wound that tolerance open surgery is brought, therefore the operation method of various Wicresoft is applied to clinical gradually, and is subject to the attention of patient and doctor.
Resectoscope is generally made up of endoscope and plasma bipolar electrode, plasma bipolar electrode is connected on below the mirror bar of endoscope by the fixing sliding sleeve parallel sleeve on its bar, medical personnel make electrode slide anteroposterior, power generator passes through Electrode connection wire by high frequency energy delivery to electrode front end, before electrode, tissue vaporization is separated rapidly by end in contact target tissue, realizes the excision of prostatic hyperplasia and urethral stricture place scar tissue.Because plasma is that charged particle by decompositing directly interrupts molecular link, be different from Common radio frequency and produce heat effect by molecular friction, therefore it can (100KHz) be cut tissue by lower temperature (40-70 DEG C), be melted under lower radio frequency, decrease the hot injury of tissue, thus achieve Mild wound.
CN 201492495 U, CN 102846375 A and CN 201398997 individually disclose a kind of resectoscope plasma bipolar electrode, it is primarily of working electrode, loop electrode, ceramics insulator and wire composition.The working electrode of existing plasma dipolar resectoscope electrode is semi-annular shape, during use, wire is by high frequency energy delivery to working electrode, and working electrode slidably reciprocates by medical personnel in focus, thus realizes the excision of prostatic hyperplasia and urethral stricture place scar tissue.There is following defect in this modus operandi: when working electrode slidably reciprocates in human prostate and urethra, because the dynamics of medical personnel is held inaccurate, and the normal structure of working electrode very easily scratch affected area, thus bring secondary damage to patient.
Summary of the invention
The purpose of this utility model is for above-mentioned defect, provide a kind of can not the normal structure of scratch affected area, the resectoscope plasma bipolar electrode that operation safety is higher.
Above-mentioned purpose is realized by following technological means:
A kind of resectoscope plasma bipolar electrode, comprise working electrode, described working electrode is U-shaped, described working electrode is arranged with several beckets.
The overall diameter of described becket is 2 ~ 3 times of working electrode diameter.
This utility model is by increasing becket on the working electrode (s, during work, high-frequency energy conducts to becket by working electrode, when working electrode slides in focus, becket can roll at affected area, thus realizes the cutting of lesion tissue and melt, this mode is compared with traditional working electrode, significantly can not only reduce the injury of normal tissue and the risk of secondary damage, and can not increase the difficulty of operation, medical personnel's operation is more convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-working electrode, 2-loop electrode, 3-ceramics insulator, 4-wire, 5-becket.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, this utility model is described in detail.
Embodiment, as shown in Figure 1, a kind of resectoscope plasma bipolar electrode, it is primarily of working electrode 1, loop electrode 2, and ceramics insulator 3 and wire 4 form, and its concrete structure and setting can see the patent publication us of CN102846375 A.The working electrode 1 of the resectoscope plasma bipolar electrode in the present embodiment is U-shaped, and several beckets 2 sheathed side by side on working electrode 1, the overall diameter of becket 2 is 2 times of working electrode 1 diameter.
This utility model is applicable to cutting, the ablative surgery of urethral stricture, obturation, prostatic hyperplasia, hypertrophy, tumor of bladder and gynecological's Sonography in Uterine Cavity Diseases tissue.It has the following advantages: 1) can more accurately and rapidly cut little block organization, and during cutting, working electrode 1 can not scratch normal structure, thus reduces the risk of secondary damage.2) sheathed multiple becket 2 is compared with sheathed single cylinder, and cutting is more accurate, can reduce the difficulty of operation, and medical personnel's operation is more convenient.
