Abstract
The invention discloses a guide sheath tube of a ureter and relates to a guide sheath tube for a patient with urinary stones, which is widely applied to an operation of getting out urinary stones. The guide sheath tube of the ureter comprises a tube body and a supporting rod, wherein the tube body is a long tube which is through from top to bottom; a strip-shaped supporting rod is arranged at one side of the tube body; the lower end of the supporting rod extends out of the tube body; the supporting rod is parallel to the axial circle center of the tube body; the upper end of the supporting rod is parallel to the upper end of the tube body or higher than the tube body; an O-shaped supporting ring or a through supporting tube is arranged at the upper end of the tube body; the O-shaped supporting ring is a solid circular ring or a hollow circular ring; when the O-shaped supporting ring is the hollow circular ring, an infusion pipeline is arranged on the tube body below the circular ring; the infusion pipeline is communicated with the O-shaped supporting ring; the tail end of the infusion pipeline is as long as the tube body, or longer than the tube body; the infusion pipeline extends out of the tube body.
Description
Technical field
A kind of ureter guiding of the present invention sheath pipe relates to the guiding sheath pipe for getting rid of urinary stone patient, is widely used in the operation of taking out lithangiuria.
Background technology
In clinical urological technology field, the academic problem how that calculus is safe in ureter, painless taking-up is continuous research and development always.Under extracorporeal shock wave, ureteroscope, under ultrasonic lithotripsy, Approach during Ureter Renal Scopy Lithotripsy, ureteroscope, lasertripsy at present conventionally gets stone operation method.For preventing and reducing calculus broken calculus is to the drift of renal pelvis in rubble process, and residual in urine output body, also there is the operating theater instruments of much getting stone and shutoff in this area, such as stone extraction basket, calculus catching net-like means, occlusion catheter; Although there is so many technical scheme and apparatus, due to the many disadvantages of design aspect, still can not accomplish convenience, safe, the painless intra-ureteral calculus of taking-up patient, so be necessary that designing a kind of new apparatus meets actual operation demand.
Summary of the invention
The object of the invention is to for above-mentioned weak point, provide a kind of ureter guiding sheath pipe, by placing the support bar of toughness in sheath pipe, the effective sheath pipe that supports launches and ensures the smooth and easy of sheath tube passage in ureter, has ensured that patient safety takes out calculus reliably.
A kind of ureter guiding sheath pipe takes following technical scheme to realize:
A kind of ureter guiding sheath pipe is made up of body, support bar; Described body is the long tube of up/down perforation, is provided with the support bar of strip in the side of body, and the lower end protruded tube of support bar is external, and support bar is parallel with the axial center of circle of body.
The upper end of described support bar flushes with body upper end or higher than body.
Described body upper end is provided with " O " shape support ring or through stay pipe.
Described " O " shape support ring is solid annulus or the annulus of hollow.
When described " O " shape support ring is the annulus of hollow, the body below annulus offers infusion line, infusion line communicates with " O " shape support ring, and the end etc. of infusion line is longer than body; Or be longer than body, infusion line protruded tube is external.
Described stay pipe is metal tube, woven tube of wire, carbon fiber knit pipe, macromolecular material braided tube.
When described " O " shape support ring is solid annulus, " O " shape support ring is becket, carbon fiber knit ring or macromolecular material braided ring.
When described " O " shape support ring is the annulus of hollow, " O " shape support ring is the ring that macromolecular material is made, as latex ring, falope ring.
A kind of ureter guiding of the present invention sheath pipe is skillfully constructed, structure is simple, result of use is good, by placing the support bar of toughness in sheath pipe, effective support sheath pipe launches and ensures the smooth and easy of sheath tube passage in ureter, in addition, also by " O " shape support ring of arranging in body upper end or through stay pipe ensure that get stone time, smooth and easy during calculus admission passage, the various apparatus for getting stone is by the pipeline of hollow in body, safety, enter smoothly in the body of patient, patient is without misery when taking out stone by force in use, ensure that patient safety takes out calculus reliably, there is higher use promotional value.
