Description
Technical field
This utility model relates to urological surgery field, and particularly a kind of urinary tract soft lens is got stone working sheath.
Background technology
Ureter soft lens operation is a kind of Minimally Invasive Surgery for upper lithangiuria, or percutaneous kidney approach operation open with tradition compared, the operation of ureter soft lens have wound little, recover the advantage such as fast, be widely used in urological surgery at present.But upper Renal Ureteral Stones is carried out after ureter soft lens operation crushed stone, the calculus fragment shattering in art remains in patient's renal pelvis, be difficult to rapid discharge, the apparatus collections such as calculus catching net-like means that wherein the relatively large calculus fragment of minority can configure by soft lens are taken out, the use cost of calculus catching net-like means is higher, the efficiency that gathers taking-up calculus crispy slice is lower, the cost of getting stone is increased, and the urine of remaining most of tiny calculus particle can only rely on patient self to urinate time taking out of is gradually external, long by the urine calculus cycle, efficiency is low, be difficult to thorough calculus, the calculus particle remaining in renal pelvis easily forms new calculus, make some patients were may occur thoroughly need to again not be in hospital operative treatment or cause that in calculus process hematuria appears in patient of calculus, urinary tract infection, the complication such as renal colic, patient's medical burden and pain have been increased.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of urinary tract soft lens to get stone working sheath, and it is simple in structure, uses cheaply, improves ureter soft lens operation lithagogue rate, alleviates patient's medical burden and pain.
The technical solution of the utility model is: two-chamber working sheath comprises for stretching into the two-chamber sheath pipe and the horn-like apparatus receptacle of being located at two-chamber sheath pipe near-end in body, described two-chamber sheath pipe is the flexible pipe of length 300～500mm, described two-chamber sheath pipe is provided with two access openings that axially run through, one of them is main service aisle, the hole girth of this main service aisle is 13～15mm, another is waterflood path, the hole girth of this waterflood path is 3～5mm, the main service aisle of two-chamber sheath pipe and the distal port of waterflood path are all positioned at the same axial end of two-chamber sheath pipe, the osculum end of described horn-like apparatus receptacle is fixedly connected with two-chamber sheath pipe, horn-like apparatus receptacle has the horn mouth being communicated with main service aisle and the water-supply-pipe interface being communicated with waterflood path, described water-supply-pipe interface is positioned at the lateral wall of apparatus receptacle, water-supply-pipe interface extends bell-mouthed big opening end.
Described two-chamber sheath pipe adopts vinyon to make.
On the outer peripheral face of described two-chamber sheath pipe, apply politef lubricant coating.
Described horn-like apparatus receptacle adopts the molding of ABS hard plastic injection molding.
The near-end of the osculum end of described horn-like apparatus receptacle and two-chamber sheath pipe is fixed by bonding or heat seal.
The elongated end of described water-supply-pipe interface is provided with screw thread.
Adopt technique scheme: a kind of urinary tract soft lens is got stone working sheath, described two-chamber working sheath comprises for stretching into the two-chamber sheath pipe and the horn-like apparatus receptacle of being located at two-chamber sheath pipe near-end in body, as long as by after the big opening end of the head end insertion instrument receptacle of soft lens, the head end of soft lens will insert smoothly two-chamber sheath pipe and enter patient's renal pelvis, the horn mouth of horn-like apparatus receptacle can play guide effect to entering of soft lens, is conducive to operator and efficiently soft lens is inserted in sheath pipe.Described two-chamber sheath pipe is the flexible pipe of length 300～500mm, and the flexible pipe that length is 300～500mm inserts after urethra, can arrive renal pelvis along patient's urethra, and flexible pipe is crooked along urethra, can not damage patient's urethra.Described two-chamber sheath pipe is provided with two access openings that axially run through, one of them is main service aisle, and the hole girth of this main service aisle is 13～15mm, and soft lens can be from main service aisle by entering patient's renal pelvis, another is waterflood path, and the hole girth of this waterflood path is 3～5mm.Because the aperture of the aperture ratio waterflood path of main service aisle is large, when soft lens rubble finishes, soft lens can be larger rubble from main service aisle, take out, the tiny particle that cannot take out for the soft lens remaining in renal pelvis, by waterflood path, to patient's renal pelvis, inject low-pressure water, low-pressure water forms eddy current and washes away remaining particle in patient's renal pelvis, makes current flow out and excrete from main service aisle with particle.After flushing finishes, also can again insert soft lens from main service aisle, observe the flushing situation of calculus particle, until calculus particle is flushed out to patient's renal pelvis completely.The main service aisle of two-chamber sheath pipe and the distal port of waterflood path are all positioned at two-chamber sheath tubular axis end face, the distal port of main service aisle and waterflood path is positioned at same axial end, two passwaies are all positioned at renal pelvis mouth simultaneously, the distal port that the particle that can make to be flushed away enters main service aisle as soon as possible, avoids particle to remain in renal pelvis.The osculum end of described horn-like apparatus receptacle is fixedly connected with two-chamber sheath pipe, horn-like apparatus receptacle has the horn mouth being communicated with main service aisle and the water-supply-pipe interface being communicated with waterflood path, described water-supply-pipe interface is positioned at the lateral wall of apparatus receptacle, water-supply-pipe interface extends bell-mouthed big opening end, water-supply-pipe extends bell-mouthed big opening end, when patient being implemented to soft lens operation, the apparatus receptacle of the hand-holdable two-chamber sheath of doctor pipe, convenient operation.
On the outer peripheral face of described two-chamber sheath pipe, apply politef lubricant coating, two-chamber sheath pipe is little at resistance when patient's urethra inserts renal pelvis, few to the stimulation of patient's urethra, is convenient to insert.
Below in conjunction with the drawings and specific embodiments, be further described.
