Abstract

The utility model discloses a multifunctional urethra small resectoscope used in the surgery of anterior urethral stricture in adults, which includes a resectoscope sheath, an obturator, an operation hand piece, a needle-shaped electrode, an electrode and a visual tube, wherein, an intubation channel is arranged on the resectoscope sheath, an electrode channel is arranged above a visual tube channel which is arranged in the operation hand piece, the axis line of a cutter of the needle-shaped electrode is perpendicular with the axis line of an operation rod of the needle-shaped electrode; the utility model can cut the oral incision or abdominal incision in the conventional complex anterior urethral stricture free mucosa grafting urethroplasty when carrying out the operation of the patients with complex anterior urethral stricture by using the multifunctional urethra small resectoscope, thus reducing the trauma and bleeding of the patients; shortening the operation time, reducing the workload of the operators; increasing the intubation function of the small resectoscope, reducing the assisted intubation application of the auxiliary mirror, such as ureteroscopy; and the operators can carry out the operation under the direct view, thereby reducing the blindness of the operation and increasing the success rate of the surgery.

Description

The little resectoscope of multi-functional urethra of anterior urethral stricture operation is used to be grown up

Technical field

The present invention relates to medical instruments field, particularly relate to the little resectoscope of a kind of multi-functional urethra, belong to the Urology Surgery field.

Background technology

The complexity anterior urethral stricture that surpasses 3 centimetres is a difficult problem of Urology Surgery, best at present Therapeutic Method is to adopt mucous dncts free grafting urethroplasty, excision narrow section urethra, get the oral mucosa or the intestinal mucosa of respective length, make with the tubulose of urethra anastomosis to substitute narrow urethra.Adopt this method need make two otch, operating time is long, and the patient is damaged greatly.

The utility model content

At the deficiencies in the prior art, the purpose of this utility model just provide a kind of patient easy to use can alleviate patient's workload be used to be grown up the little resectoscope of multi-functional urethra of anterior urethral stricture operation.

For achieving the above object, this utility model is a kind of be used to the to be grown up little resectoscope of multi-functional urethra of anterior urethral stricture operation, comprise mirror sheath, obturator, operation hand piece, needle electrode and look pipe, wherein, described mirror sheath is provided with cannula passage, the tube passage top of looking in the described operation hand piece is provided with electrode channel, and the axis of the cutter of described needle electrode is vertical mutually with the axis of the action bars of needle electrode.

Further, the described diameter of looking pipe is 2.7 millimeters.

Compared with prior art, adopt this utility model be used to be grown up little resectoscope of multi-functional urethra of anterior urethral stricture operation, when complexity anterior urethral stricture patient is undergone surgery:

1, deducts the free mucous dncts of conventional complexity anterior urethral stricture and transplant oral cavity otch or abdominal incision in the urethroplasty, reduce patient's wound and hemorrhage;

2, shorten operating time 1/3, alleviate the workload of operator;

3, increase the intubate function of small mirror, reduce the auxiliary intubate of auxiliary mirror such as ureteroscope and use.

4, patient's operation under direct-view reduces the blindness of performing the operation, and increases the success rate of operation

The specific embodiment

Shown in Fig. 1-5, this utility model be used to the to be grown up little resectoscope of multi-functional urethra and common children's's resectoscope of anterior urethral stricture operation is basic identical, mirror sheath 1 by 12F, obturator 3, operation hand piece 4, needle electrode 5 and 2.7 millimeters are looked pipe 6 and are formed, both are difference: this utility model is used to be grown up and has additional cannula passage 2 on the mirror sheath 1 of the little resectoscope of multi-functional urethra of anterior urethral stricture operation, the tube passage top of looking in the operation hand piece 4 has additional electrode channel 7, the axis of the cutter 8 of needle electrode 5 is vertical mutually with the axis of action bars 9, and promptly the angle a between them is 90 degree.

As shown in Figure 6, we find in clinical position, the anterior urethral stricture pathological change, diameter is ascending to be divided into the narrow section D of center, two narrow section C, two subnormal section B of next-door neighbour central authorities, be normal reach A toward both sides again, advance toward bladder that diameter successively decreases from external orifice of urethra, diameter increases progressively then, i.e. normal reach A---subnormal section B---inferior narrow section C---narrow section D---inferior narrow section C---subnormal section B---normal reach A.

Original children's's resectoscope does not have insertion hole, can not place seal wire and ureteral catheter (sign when doing to cut), needs other apparatus auxiliary; Diameter is too little, reaches 18F when above when cutting narrow positions urethra, because diameter does not match, is difficult for finding remaining narrow positions, and urethra can not return to the normal range of 24F, and operation has big difficulty to adult's anterior urethral stricture.Therefore, this utility model increases cannula passage 7 newly, makes it can intubate, again can TURP, removed use ureteroscope intubate from; In addition, at the electrode channel 7 above the tube passage of looking newly-increased of operation hand piece 4, be convenient to needle electrode 5 runnings.

Below by concrete operation, explain in detail the using method of the little resectoscope of multi-functional urethra that the anterior urethral stricture that is used to be grown up is performed the operation, and in conjunction with in equipment such as resectoscope, complexity anterior urethral stricture incremental urethra patient has been designed " diameter incremental internal urethrotomy ":

Patient Ma Peinan, in complexity anterior urethral stricture June behind the prostatic hyperplasia vaporization electrotomy, the urine retention bladder is made the flaccidity postoperative, drains VCU and shows: 9 centimetres of anterior urethral strictures.In in October, 2005 at the descending diameter incremental of continuous epidural anesthesia internal urethrotomy:

1, inserts the mirror sheath 1 that has obturator 3 and insert 1.5 centimetres in urethra, pull out obturator 3; Change operation hand piece 4 and look pipe 6, under direct-view, mirror sheath 1 is arrived at urethra time narrow C, observe the diameter of seeing the narrow D of urethra and only be 2 millimeters thick; Insert 25 centimetres of zebra seal wires through cannula passage 2, make it enter bladder by narrow urethra.Mirror sheath 1 is withdrawed from, keep somewhere the zebra seal wire and in urethra, make Warning Mark;

2, mirror sheath 1 is inserted in direct-view down once more, with needle electrode 5,50 watts of power, indicate that with the zebra seal wire tip alignment seal wire of needle electrode 5 utilizes the cutter 8 at right angle, retrograde TURP is opened 12 positions of narrow urethra, cut edge and to push away mirror sheath 1 in the limit, by the narrow D of urethra, nearly bulb urethra is just seen normal urethra; Inferior narrow C at the narrow D of urethra and its two ends is further cut in direct-view down direct motion, and with the cutter 8 of needle electrode 5, the scar tissue of projection is excised in the side, pulls out the zebra seal wire;

3, cut mirror among the 19F of tape swapping flushing interface, observation and inspection urethra situation is further cut urethra narrow D, inferior narrow B and subnormal C;

4, the middle incision mirror of tape swapping epitheca further excises stenotic tissue, makes the urethra internal diameter reach normal standard;

5, use urethra stand successive dilating urethra to 26F, keep somewhere the 22F Foley catheter, art finishes.

Postoperative 3 all tube drawings, unobstructed micturition, regularly dilating urethra is 6 times, and urethra can pass through 24F probe after March, cures.
