Abstract
The utility model provides a resectoscope electrode for a minimally invasive surgery, and the resectoscope electrode comprises an insulating sleeve, double-core wires, a cutting electrode, a loop electrode, an insulating tube and a wiring terminal, wherein the double-core wires are arranged in the insulating sleeve, the front end of the insulating sleeve is provided with the cutting electrode and the loop electrode which are respectively connected with one of the double-core wires, the ends of the cutting electrode and the loop electrode are connected through the insulating tube so as to maintain a gap, the wiring terminal is arranged at the tail end of the insulating sleeve, the cutting electrode is shaped like a ring-shaped shovel, and the angle formed by the cutting electrode and the main rod part of the resectoscope electrode is larger than 90 degrees. The resectoscope electrode can perform push cutting and tissue stripping on an affected part in a forward-shoveling manner, so that doctors can perform transurethral electro-prostatectomy conveniently, the surgery efficiency and the tissue excision effect are improved, the target tissues can be excided more radically, the rice crust shoveling type excision effect is achieved and the operating manners of the existing resectoscope electrode are enriched.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to the used electrode of resectoscope that Minimally Invasive Surgery is used.
Background technology
Prostate hyperplasia, hypertrophy are the high common diseases of middle-aging male sickness rate, and the excision that undergos surgery is an efficacious therapy method the most.Traditional open surgery is to cut an otch at patient's hypogastric region, cuts the dirty taking-up prostate of wing again, and this is very big to normal urethra physiological structure damage.And the sick majority of prostatic hyperplasia is the old people, and they are difficult to tolerate the wound that open surgery is brought often with other serious disease, and therefore the method for the per urethra internal therapy prostatic hyperplasia of various Wicresofts receives Urology Surgery doctor's very big attention.Transurethral resection of prostate mirror electrotomy is invented in American-European developed country, because this operation need not on human body, to operate on, has significantly reduced wound, is generally acknowledged it is " goldstandard " of current treatment prostatic hyperplasia.
Resectoscope generally is made up of endoscope, interior sheath, epitheca, operation hand piece and electrode; Electrode is connected on the mirror bar below of endoscope through the fixedly sliding sleeve parallel sleeve on its bar; The electrode rear end patches on the Fixing clamp-seat of operation hand piece, and operator's operation hand piece slides before and after making electrode, and power generator connects lead through electrode high frequency energy delivery is arrived the electrode front end; The end in contact target tissue separates tissue vaporization rapidly before the electrode, realizes the excision of prostatic hyperplasia.The operation method of this resection of prostate all is that steering electrode is by going to the back to move (electrode stretches out endoscope the place ahead and back cuts then) all the time; Promptly by the past prostate front end mute tissue (method of promptly striking off) in prostate rear end; The front end of electrode is annular hoe shape; Angle between TURP ring and the electrode stem is less than 90 degree, generally between 70～85 degree.The shortcoming that this method exists is that resection organization is incomplete, and the late relapse rate is high.A kind of in recent years new operation method; It is the transurethral resection of prostate enucleation; Owing to can more fully excise prostate, clinical effectiveness has reached the effect of open operation, obtains numerous doctors' approval and pursues; Its method is to cut out backward except that prostate from prostate front end edge surgery peplos, and electrode will be implemented pushing away of separating interface cut and stopped blooding when chorista.Traditional hoe shape electrode when implementing this operation, exist be difficult to push away cut, bad hemostasis and damage the shortcoming of electrode easily.
The utility model content
This utility model provides a kind of novel Minimally Invasive Surgery to use the resectoscope electrode in view of the above problems, and this purpose is realized by following technical scheme:
A kind of Minimally Invasive Surgery is used the resectoscope electrode, comprises insulation sleeve, duplex wire, cutting electrode, loop electrode, insulation tube and binding post; Be provided with duplex wire in the insulation sleeve; The front end of insulation sleeve is provided with cutting electrode and loop electrode; Cutting electrode and loop electrode respectively with duplex wire in one be connected; The end of cutting electrode and loop electrode is connected to keep one at interval through insulation tube, and the end of insulation sleeve is provided with binding post; It is characterized in that: said cutting electrode is set to annular shovel shape, its with the mobile jib portion of resectoscope electrode between angle spend greater than 90.
Angle is preferably 110～160 degree between the mobile jib portion of said cutting electrode and resectoscope electrode.
Described insulation sleeve periphery also is provided with fairlead.
Described insulation sleeve periphery also is provided with sealing shroud.
The beneficial effect of this utility model is: can push away patient part with the mode of shovel forward and cut and tissue is peeled off; Being convenient to the doctor implements transurethral resection of prostate and cuts out and remove operation; Improve operation efficient and cutting tissue effect; Make the excision of target tissue more thorough, reached the excision effect of " shovel rice crust " formula, enriched the mode of operation of existing resectoscope electrode.
Description of drawings
The vertical view of the resectoscope electrode that Fig. 1 provides for embodiment.
The side view of the resectoscope electrode that Fig. 2 provides for embodiment.
The front end zoomed-in view of the resectoscope electrode that Fig. 3 provides for embodiment.
The specific embodiment
Resectoscope electrode as shown in Figure 1, that present embodiment provides comprises insulation sleeve 11, duplex wire 12, cutting electrode 13, loop electrode 14, insulation tube 15, fairlead 16, sealing shroud 17 and binding post 18.
Be provided with duplex wire 12 in the insulation sleeve 11; The front end of insulation sleeve 11 is provided with cutting electrode 13 and loop electrode 14; Cutting electrode 13 and loop electrode 14 respectively with duplex wire 12 in one be connected, both ends of cutting electrode 13 and loop electrode 14 are connected to keep one at interval through insulation tube 15.The end of described insulation sleeve 11 is provided with binding post 18.Described duplex wire 12 extends out from binding post 18, the tail end of duplex wire 12 and then be connected to the plug (not shown).Described insulation sleeve 11 peripheries also are provided with fairlead 16 and sealing shroud 17.
The main feature of the resectoscope electrode that present embodiment provides is: cutting electrode 13 is set to annular shovel shape, and promptly angle is preferably 110～160 degree greater than 90 degree between the mobile jib portion of cutting electrode 13 and resectoscope electrode.Thus; The resectoscope electrode that present embodiment provides just can push away patient part with the mode of shovel forward and cut and tissue is peeled off; Be convenient to the doctor and implement transurethral resection of prostate and cut out and remove operation, improve operation efficient and cutting tissue effect, make the excision of target tissue more thorough; Reach the excision effect of " shovel rice crust " formula, enriched the mode of operation of existing resectoscope electrode.
Above embodiment is merely fully open and unrestricted this utility model it is understandable that, also there are some conspicuous distortion in this utility model, should also belong to the scope that the application discloses.
