Description
Technical field
The present invention relates to a kind of seal wires for urological surgery.
Background technique
All stone operations of Urology Surgery at present are required to use ureter seal wire, and stone operation is used toward contact needs
Ureteral calculi plugging device or stone basket, surgical material total cost are high.Currently on the market circulation or already present seal wire often
It has a single function or complicated for operation.
Summary of the invention
The present invention is intended to provide one kind is easy to operate, multiple functional, collection ureter seal wire, ureteral calculi plugging device, takes
Four kinds of integrated multi-functional seal wires of function of stone basket (crawl biopsy).Realize that the technical solution of above-mentioned purpose is as follows:
Multi-functional uriniferous pipe seal wire, including inner core further include outer core, and one end of outer core is head, and one end is tail portion,
The axle center of outer core has a bellmouth, and the bellmouth is blind hole, has bottom hole and Kong Ding；Head to caudal directions, institute
Bellmouth aperture is stated to be gradually increased；It is wherein bottom hole close to cephalad direction, is hole top close to caudal directions；
The bottom hole to head position forms blind section of head, and Kong Dingzhi tail position forms blind section of tail portion；Meanwhile apart from hole
It pushes up at the position 0.5-1cm, opening is set on outer core, the opening is connected to bellmouth；
Outer core is also conical structure simultaneously, outer core head to caudal directions, the conical structure it is straight
Diameter is gradually increased；
Inner core is inserted into the bellmouth, blind section of one end and the head of the inner core is fixed together, inner core it is another
One end and hole top are substantially concordant, and after outer core stress, the other end of the inner core can be stretched out from opening；The inner core and outer core
Form seal wire.
At the 2-3cm of bottom hole position, outer core be divided into several bands, institute in equal size centered on the axis of bellmouth
The length of band is stated between 1-1.5cm, when pushing against blind section of tail portion, outer core can be slided slightly, keep band swollen
It rises, the band swelled can block ureter or calculus is able to enter in the space swelled；When release blind section of tail portion strength
When, the band can bounce back, and the band of retraction wraps calculus.
The configuration of the present invention is simple, easy to operate, calculus can sufficiently be taken out of in vitro, and the pain of patient is reduced.

Specific embodiment
The present invention is described in detail with reference to the accompanying drawing.
Multi-functional uriniferous pipe seal wire includes outer core 1, inner core 2, and one end of outer core 1 is head, and one end is tail portion, described
The axle center of outer core 1 has a bellmouth 3, and the bellmouth 3 is blind hole, has bottom hole and Kong Ding；Head is described to caudal directions
3 aperture of bellmouth is gradually increased；It is wherein bottom hole close to cephalad direction, is hole top close to caudal directions；Bottom hole is to head
Position forms blind section of head 4, Kong Dingzhi tail position and forms tail portion blind section 5；Meanwhile it being pushed up at the position 0.5-1cm, outside apart from hole
Setting opening 6 on core 1, the opening 6 are connected to bellmouth 3, and about in 0.5cm or so, specific width preferably makes interior 6 length that are open
Core 2 can stretch out here to be advisable；Outer core 1 is also conical structure simultaneously, 1 head of outer core to caudal directions, described
The diameter of conical structure is gradually increased.
Inner core 2 is inserted into bellmouth 3, inner core 2 plays the role of guidance and support, slightly has between inner core 2 and bellmouth 3
Point gap, 3 inner wall roughness precision of bellmouth is high, and inner core 2 can be reduced between 3 inner wall of inner core 2 and bellmouth when insertion
Frictional force, in this way, inner core 2 can facilitate in insertion bellmouth 3, wherein the gap between inner core 2 and bellmouth 3 can be allowed outer
Core 1 is slightly mobile.
One end of the inner core 2 is fixed together for blind section 4 with head, and the other end of inner core 2 and hole top are substantially concordant,
After outer 1 stress of core, outer core 1 can be appropriately extended, and the other end of the inner core 2 can stretch out from opening 6；When inner core 2 is complete
When in bellmouth 3, inner core 1 and outer core 2 form complete seal wire, and function is consistent with normal market circulation seal wire, rises and draws
Lead effect.
When needing 2 other end of inner core (i.e. close to inner core one end of opening 6) to stretch out opening 6, clamped using clamp
Blind section of tail portion exerts a force slightly outwards, to make to pass through opening 6 close to the inner core end of opening；
The direction of head to tail portion, at the about 2-3cm of bottom hole position, the quilt centered on 3 axis of bellmouth of outer core 1
It is divided into 3-4 item or more a plurality of band, the radical of specific band can be adjusted freely according to the diameter of outer core 1, herein
Band play the role of gathering, the length of band is about between 1-1.5cm or so.
Most critical position of the present invention is outer core 1, and the material of outer core 1, which needs to choose, has certain elasticity, intensity and toughness
Material, preferably outer 1 material of core be high molecular material or polyvinyl chloride (PVC), polyethylene (PE), perfluoroethylene-propylene (F46),
Nylon, polyolefin etc..Such material has durable characteristic.The inner core chooses the metal with some strength and toughness
Material production, such as stainless steel material, nickel alloy, titanium alloy etc..
In order to keep clean, be socketed seal wire sheath in the external of seal wire (i.e. outer core), the needs stretching of blind section of the head of outer core is led
Crosisure, blind section of tail portion is concordant with the tail portion of seal wire sheath, and seal wire sheath is equivalent to again to one outer packing of seal wire.The length of general seal wire
It is all long, when carrying other than using seal wire sheath to be protected, also the seal wire with seal wire sheath can be surrounded by number
Circle, product is blocked, seal wire is avoided to wind mutually using seal wire sheath cutting ferrule.
When use, seal wire is taken out from seal wire sheath, one clamps blind section of tail end Wen's pincers, and one presss from both sides Wen's pliers
Firmly blind section of head, two Wens pincers slightly it is suitable it is reversed firmly, outer core extends 1 elastic force effect end is suitable, and metal inside is from opening 6
It stretches out.
Then it by blind section of head insertion calculus 7, later in blind section of the tail portion of outer core 1 force, is gently pushed for blind section to head,
Outer core 1 slightly moves, at this point, secular upheaval adjusts the band on outer core 1 according to ureter lumen size under force
Firmly size stops ureter, calculus must not continue to move up migration, referring to Fig. 4 so that band folds.
When calculus is crashed to pieces as compared with fractionlet, when calculus further being smashed again due to Bladder stone inconvenience, adjustable seamless
The firmly strength of blind section of tail portion makes the band folded retraction, swells, since band material has certain degree of hardness, during swelling,
It will form cavity between band, broken calculus completely or partially enters in cavity, keeps inner core motionless at this time, then pressing is existed
The strength release that blind section of tail portion, outer core retraction, gradually drives band tightening, calculus is fixed, finally pulls out entire seal wire
In vitro, while seal wire is followed positioned at intraluminal calculus while being removed external.Certainly, in the operation of the rubbles such as new Flexible ureteroscope
Seal wire can be used.Its function is stone basket at this time.Referring to Fig. 5, Fig. 6.
The above is only the preferred embodiments of the embodiment of the present invention, are not intended to limit the invention embodiment, all at this
Within the spirit and principle of inventive embodiments, any modification, equivalent replacement, improvement and so on be should be included in of the invention real
It applies in the protection scope of example.
