Abstract

The invention provides a ureter rapid bidirectional catheterization device under a laparoscope and an application method of the ureter rapid bidirectional catheterization device, and relates to the field of medical equipment. The catheterization device comprises a sheath and an inner core, wherein the sheath is in a kidney-shaped flat tube shape, and movably sleeves the outer part of the inner core; smooth circular-arc notches are formed in circular-arc parts at the two sides of the kidney shape of the front end of the sheath respectively; a slide groove with an opening in one end is formed in the front surface of the sheath; the inner core is composed of a column section and a trapezoid block; when the inner core is arranged in the sheath, a guide hole is formed among two inclined planes of the trapezoid block and the inner wall of the sheath; the guide hole is used for guiding a double-J-shaped tube to the circular-arc notches at the two sides of the end part of the sheath. The application method comprises the following steps: corresponding the circular-arc notches at the two sides of the end part of the sheath to upper and lower ends of an incision of the ureter respectively; inserting a guide wire and the double-J-shaped tube into the upper and lower ends of the incision of the ureter respectively by using the guide hole and the circular-arc notches; then pulling out the sheath and continually pushing the double-J-shaped tube until the whole double-J-shaped tube is inserted into the ureter. The ureter rapid bidirectional catheterization device is relatively simple to operate, high in efficiency and small in wound trauma.

Description

The quick two-way tube placing device of ureter and using method thereof under laparoscope

Technical field

The present invention relates to medical instruments field, the quick two-way tube placing device of ureter and using method thereof under especially a kind of laparoscope.

Background technology

At present, Urology Surgery circle, carrying out in renal plevis and operation on ureter, need to be placed a ureter bracket in patient's ureter clinically, is commonly called as " two J type pipe ", after about 1-2 month after surgery, then extracts with cystoscope per urethra. This ureter bracket, can play the effect of support and drainage, thereby ensures that urine drainage is smooth and easy, avoids or reduce the generation of the situations such as urine extravasation, the infection of kidney week and urinary tract are narrow. " two J type pipe " the common method of placing in laparoscopic surgery is for first utilizing the two J type pipes of seal wire guiding one end to be inserted in ureter, then utilize the instruments such as operating forceps, the other one end of two J type pipe is also inserted in ureter, operate more loaded down with trivial details, put pipe difficulty large, length consuming time, wound for otch is larger, especially for new hand's difficult problem especially, if design a kind of device that contributes to quick intubate, the quick two-way tube placing device of ureter just can address this problem, so can significantly improve operation efficiency and reduce damage under design laparoscope.

Summary of the invention

The object of the invention is to provide to this area the quick two-way tube placing device of ureter and using method thereof under a kind of laparoscope, making it solve existing ureter, to put pipe operation comparatively loaded down with trivial details, and operation efficiency is the end of compared with, the larger technical problem of mouthful wound of easily causing injury. It solves by following technical solution.

The quick two-way tube placing device of ureter under this laparoscope, it comprises epitheca, inner core, epitheca pivot bush unit is in inner core outside; Described epitheca is waist type flat tube shape, and the circular arc position, kidney-shaped both sides of epitheca front end is respectively equipped with smooth arc gap, and the front of epitheca is provided with the chute of an end opening, and the openend of chute is positioned at the front end of epitheca; Described inner core comprises shell of column, trapezoid block, shell of column is connected with the end face of trapezoid block, and be smooth transition between the inclined-plane, both sides of trapezoid block and shell of column, shell of column outside is fixedly connected with slide block, the chute of slide block and described epitheca is slidably matched, and in the time that slide block slides into positive stop end along chute, the bottom surface of described trapezoid block flushes with the front end face of described epitheca, between the inclined-plane, both sides of trapezoid block and epitheca inwall, form pilot hole, this pilot hole is for being directed to two J type pipes the arc gap of both sides, described epitheca end. By design arc gap in both sides, epitheca end, and in the time that epitheca coordinates with inner core, both inside are formed for the pilot hole of two J type pipe guiding, thereby the two J type pipes in convenient promotion epitheca are along both sides, epitheca end guiding movement, corresponding with the upper and lower end ureter direction of ureter otch, operation more for convenience, improves ureter and puts pipe operation efficiency and success rate.

The shell of column of described inner core is rectangle shell of column, and pitch match between two parallel surfaces of the thickness of this rectangle shell of column and described epitheca. By this structure, improve the stability of inner core and epitheca relative motion, thereby improve the stability of putting pipe operation.

The inclined-plane, both sides of the trapezoid block of described inner core is provided with the gathering sill of circular arc indent. By this structure, make the inclined-plane, both sides of trapezoid block there is better guide effect to two J type pipes, more smooth while promoting two J type pipe.

Described slide block connects hand-held pole, and hand-held pole end is provided with buckle, and in the time that hand-held pole slides into described chute positive stop end with described slide block, buckle and described epitheca end fasten. By this structure, when inner core is put in place with respect to epitheca insertion, both form temporary fixed, improve the stability using.

Described epitheca rear end socket rubber cap, rubber cap is provided with and is applicable to the handle hole that ducted propeller enters. By design rubber cap, there is the effect of anti-gas-leak.

Under this laparoscope, the using method of the quick two-way tube placing device of ureter is: first, inner core inserts in epitheca, and described slide block slides into the positive stop end of epitheca chute; Then, be placed in two pilot holes in described epitheca by corresponding respectively the two ends of two J type pipes, and preset seal wire in two J type pipe; Again by the arc gap of the described epitheca front end both sides upper and lower end of corresponding ureter otch respectively; Next operate seal wire, make seal wire be inserted into the ureter of ureter otch upper and lower end along the arc gap of two J type pipes and epitheca front end, utilize subsequently ducted propeller to promote described pair of J type pipe and insert respectively the upper and lower two ends of ureter along seal wire channeling direction, until ducted propeller promotes the intervalve portion of two J type pipes and the end of described inner core offsets, then extract epitheca out, epitheca and inner core are departed from, remove the restriction of inner core end to two J type pipes, continue to promote two J type pipes with ducted propeller, until two J type pipe all inserts in ureter; Finally first extract seal wire out, then exit ducted propeller, complete the two-way pipe of putting of ureter and operate.

The invention has the advantages that operation technique is comparatively simple, efficiency is high, and wound wound is little, and be suitable as medical ureter and put pipe operation use, or similar improvement of putting pipe operation method.
