Description

Bipolar electrode and draw bail thereof

Technical field

This utility model relates to a kind of medical apparatus and instruments, specifically is that a kind of and resectoscope claim resectoscopy matching used a kind of bipolar surgery electrode again.

Background technology

Resectoscope is a kind of operating theater instruments in the minimally-invasive treatment, mainly by inside and outside sheath cover, electrode, compositions such as operator and endoscope.Electrode is installed on the operator slide block, moves forward and backward by the slide block drive electrode that promotes on the operator, thereby undergos surgery operation.Resectoscope and high frequency generator claim high frequency electric knife supporting use again, are widely used in Urology Surgery, section office such as gynecological.Be mainly used in transurethral resection of the prostate hypertrophy body of gland and tumor of bladder; Gynecological is used to the fleshy polyp that hysterectomizes, illness such as endometrium.Transurethral prostatic resection (TURP) is classified as " goldstandard " for the treatment of hyperplasia of prostate at present in the world.Have to patient hit little, easy acceptance, misery less, recover advantage such as fast.But employed procedures electrode is monopolar electrode on the resectoscope at present.Monopolar electrode has only working electrode, does not have loop electrode.The monopolar electrode electric current is by human body, claims neutral electrode or minus plate formation loop again with negative plate human body under, and voltage is higher.The effect of negative plate is the high frequency electric on the monopolar electrode inflow patient body to be separated into safe low current density return in the high frequency generator, if negative plate and patient's loose contact etc., electric current focuses on the part of negative plate, and local current densities is increased, and this place's tissue will be burnt.In addition, monopolar electrode uses nonconducting flushing liquor, is easy to generate the TURP syndrome and also claims dilutional hyponatremia, is commonly called as the water intoxication phenomenon, if rescue the untimely death that causes.

In order to solve the deficiency that above-mentioned monopolar electrode exists, this utility model provides a kind of voltage lower, the bipolar electrode and the draw bail thereof of safety.This bipolar electrode is worked in normal saline, uses normal saline as flushing liquor, can prevent the TURP syndrome that monopolar electrode easily produces.This bipolar electrode itself is except that having one as the working electrode of monopolar electrode, also has a loop electrode, electric current is flowed into by working electrode and is cut tissue, gets back to elevated loop electrode by conducting medium and gets back in the high frequency generator through bipolar high-frequency line, and electric current does not pass through human body.Between working electrode and loop electrode, form plasma slab, thereby can reduce contacting of electric current and tissue, reduce tissue injury.The burn phenomenon that produces when avoiding the monopolar electrode electric current by the loose contact of human body negative plate.Through the new patent searching retrieval, not finding both at home and abroad has similar scheme report.

The utility model content:

It is a kind of in normal saline work that this utility model provides, and is installed in bipolar electrode and the draw bail thereof used on the resectoscope operator.Endoscope, inside and outside sheath cover, the plug that the operation part and the bipolar high-frequency line other end and high frequency generator link in the operator belongs to prior art, not at the design's row.The technical solution adopted in the utility model is: bipolar electrode is to separate with bipolar high-frequency line; Bipolar electrode and bipolar high-frequency line can be sterilized respectively; Electrode is a consumable goods, can change at any time during operation; By the slide block on the operator bipolar electrode and bipolar high-frequency line one end plug are linked together; With the locking wheel locking that is contained on the slide block; Slide on sleeve pipe by female finger ring, inner arm and the outer arm drive slide block that promotes on the operator, and then the drive bipolar electrode back and forth moves forward and backward the operation that undergos surgery.It is characterized in that: bipolar high-frequency line plug is inserted in the microscler flat hole below the operator slide block, and the platform control plug body on the plug body enters the degree of depth in the microscler flat hole; The straight-bar of bipolar electrode guide pipe rear portion column type is passed in the round gum cover insertion plug body that is contained on the joint; Inserted link on the working electrode in the bipolar electrode and loop electrode afterbody contact with being contained in intravital work conductive pole of plug and loop conductive pole respectively, constitute working electrode path and loop electrode path; With the inserted link on the locking wheel locking working electrode that is contained on the slide block metal guide pillar, play when preventing bipolar electrode work, locking wheel and metal guide pillar thread connection; Guide pipe on the bipolar electrode slides on endoscope's mirror pipe, play the guiding role; The straight-bar sealing of round gum cover and guide pipe rear portion column type prevents to leak when bipolar electrode from moving forward and backward; Round gum cover can be changed at any time.

Described bipolar electrode is made up of described working electrode, loop electrode and guide pipe, it is characterized in that: working electrode overcoat loop electrode also closely connects; The front end of working electrode and loop electrode current-carrying part and afterbody are respectively at a distance of a segment distance; Front end separates with round earthenware, and afterbody separates with insulation tube, prevents to form the loop; Become straight-bar again after the straight-bar bending of guide pipe rear portion column type is a bit of, sealing when being convenient to insertion and slip; Guide pipe is fixed on loop electrode flattening place, prevents to rotate.

Described bipolar high-frequency line plug, by described plug body, work conductive pole, loop conductive pole, brown covered wire, blue color covered wire and sebific duct are formed, and it is characterized in that: the work conductive pole links to each other with plain conductor in the brown covered wire; The loop conductive pole links to each other with plain conductor in the blue color covered wire; At a distance of a segment distance, prevent to produce the loop, and be fixed on the plug body between work conductive pole and the loop conductive pole; Brown covered wire and Lan Se covered wire overcoat sebific duct shield, and fix with plug body.

Described slide block slides on sleeve pipe, links to each other with operation part on the operator, it is characterized in that: a microscler flat hole is arranged below the slide block, described metal guide pillar is housed on the side, the insulation guide column sleeve; The metal guide pillar closely is connected with the metal guide column sleeve with slide block.

Described locking wheel is characterized in that: be made of metal locking bar and insulation lock nut, the metal locking bar is fixed on the insulation lock tube, has uniform circular groove on the insulation lock tube circumference, and is anti-skidding when being convenient to rotate.
