Description

The shaft-like cutting electrode of resectoscope

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 carrying out excision is the most effective Therapeutic Method.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 large 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 is subjected to Urology Surgery doctor's very big attention.Transurethral resection of prostate mirror electrotomy is invented in European and American developed countries, because this operation need not to operate at human body, has greatly reduced wound, and being recognized is " goldstandard " of current treatment prostatic hyperplasia.

It is different that existing resectoscope electrode is pressed the electrode service portion, be divided into ring-type cutting electrode (as shown in Figure 1) and shaft-like cutting electrode (as shown in Figure 2), both should different demands be applicable to different workplaces, shaft-like cutting electrode is mainly used in wearing of rectilinear direction and cuts (the similar laser straight line is worn the effect of cutting), and the ring-type cutting electrode is used for the cutting of scraping accurately the formula of digging to organizing in the subrange.

The structure of two kinds of electrodes and matching used equipment thereof are also different, are described as follows:

The matching used apparatus of ring-type cutting electrode is the resectoscope that is comprised of endoscope, interior sheath, epitheca, operating grip, electrode is connected on the mirror bar below of endoscope by the fixedly sliding sleeve parallel sleeve on its bar, the electrode rear end patches on the Fixing clamp-seat of operating grip, operator's operating grip slides before and after making electrode, power generator arrives the electrode front end by wire with high frequency energy delivery, the end in contact target tissue separates tissue vaporization rapidly before the electrode, realizes the excision of prostatic hyperplasia.

Existing shaft-like bipolar electrode is hand-held straight stock shape electrode, the ring-type cutting electrode that the Length Ratio of working beam can be installed on the handle is long more, greater than 30cm, the matching used apparatus of shaft-like cutting electrode is relatively simple, be mainly a visual sheath core with service aisle, observe on one side during operation, Yi Bian by carry out the operation technique of dead-beat with the direct push-and-pull electrode stem of hands.

Therefore, compare the supporting apparatus of ring-type anode electrode, existing shaft-like cutting electrode and matching used apparatus thereof are handling relatively poor, and reliability is not high enough, and the space of improving and promoting is still arranged.

The utility model content

This utility model provides a kind of novel resectoscope shaft-like cutting electrode in view of the above problems, can assemble and be used on the resectoscope.This purpose is realized by following technical scheme:

The shaft-like cutting electrode of a kind of resectoscope comprises metal canula, insulation sleeve, duplex wire, shaft-like anode electrode, tubulose loop electrode, insulation tube; Insulation sleeve is arranged on the metal canula outside, one in the duplex wire is passed metal canula, be electrically connected with shaft-like anode electrode, another root in the duplex wire and metal canula are electrically connected, the metal canula front end is fixedly connected with shaft-like anode electrode by insulation tube, the metal canula outer setting tubulose loop electrode of insulation tube rear end, tubulose loop electrode and metal canula are electrically connected; It is characterized in that: also comprise the operating grip counterpart, this counterpart is arranged on the end of metal canula, and duplex wire extends out from this counterpart.

As further technical scheme, the shaft-like cutting electrode of above-mentioned resectoscope also comprises the electrode guide card, and this electrode guide card lower end is fixedly connected on the metal canula outside, and the upper end arranges semiorbicular card.

The beneficial effects of the utility model are: can be assemblied on the apparatus of original use ring electrode, need not to be equipped with again special-purpose visual sheath core, function, compatibility and the reliability of traditional shaft-like cutting electrode have been improved, can substitute the prostatic hyperplasia excision of laser, prostatic hyperplasia enucleation particularly, not only the handling and accuracy of operation is better than laser, and has greatly lowered surgery cost.
