Abstract
The present invention relates to a kind of odd-shaped cross section ureter bracket, described ureter bracket is hollow tubular structure, the two ends of ureter bracket each looped-shaped bending, and described ureter bracket is many prismatics, and the tube wall of ureter bracket is provided with groove and conduction hole.Have an advantage in that: the tube wall of ureter bracket of the present invention is provided with groove, expand the space between ureter inwall and ureter bracket, be conducive to scattering and discharging of calculus, reduce the incidence rate in stone street, improve calculus clearance rate, decrease ureter bracket and ureteral contact surface simultaneously, reduce the complication of ureter wall damage.
Description
Technical field
The present invention relates to a kind of ureter bracket, specifically, be a kind of odd-shaped cross section ureter bracket.
Background technology
Ureter bracket because of its inner support and interior drainage, in the end of the seventies in last century first Application in facing
Bed, is now widely used in each operation technique of urinary system.Ureter bracket can efficient solution except upper urinary stone,
The temporary upper urinary that ureter edema causes, prevention of postoperative stricture of ureter and the generation of leakage of urine, profit
Recover in Ipsilateral renal function.In urinary system calculus Minimally Invasive Surgery, by rock breaking tools such as laser by calculus
Smashing, bigger calculus relic can be gone out by current and calculus catching net-like means takes out, the calculus of powdered (< 2mm)
Generally requiring postoperative Self-discharged, by inserting ureter bracket, calculus powder can be arranged in order along cradle wall
Going out, the interior drainage of ureter bracket keeps urinary tract unobstructed.
The ureteral cross section of human body is similar round, and traditional ureter bracket cross section is circular, inserts ureter
The rear ureter bracket tube wall external space is little, is unfavorable for scattering and discharging of calculus powder.Existing ureteric branches
Frame is during indwelling, and tube wall the most easily adheres to crystallization, periphery aperture and inner passage blocking, causes drain to lose
Lose.Ureter bracket is big with ureter wall contact area simultaneously, and the friction of tissue can be caused sticking by support tube
The pathological changes such as film congestion and edema, epithelial hyperplasia or atrophy, mucosa ulcer's formation.
There are the symptoms such as the formation of urinary tract stone street, urinary tract obstruction after putting pipe operation in patients in part clinically, needs after tube drawing
External stone crushing, operation etc. is wanted again to process.Therefore need to improve the structure of ureter bracket, after improving rubble
Calculus clearance rate, reduce urinary tract obstruction risk.
Chinese patent literature CN200810101820.4, discloses a kind of ureter bracket, ureter bracket
It is provided with two grooves differed in size, urine can be made to arrive bladder smoothly, but the cross section of this ureter bracket
For ellipse, it is relatively big with ureter contact surface, and the complication of ureter wall damage easily occurs.
About reducing the incidence rate in stone street, reduce the ureter bracket of ureter wall damage complication, mesh
Before have not been reported.
Summary of the invention
It is an object of the invention to for deficiency of the prior art, it is provided that a kind of odd-shaped cross section ureter bracket.
For achieving the above object, the present invention adopts the technical scheme that:
A kind of odd-shaped cross section ureter bracket, described ureter bracket is hollow tubular structure, ureteric branches
The two ends of frame each looped-shaped bending, described ureter bracket is many prismatics, on the tube wall of ureter bracket
It is provided with groove and conduction hole.
Described ureter bracket is prismatic.
Described groove is arranged in a linear.
Described groove arranges in the shape of a spiral.
The invention has the advantages that:
The tube wall of ureter bracket of the present invention is provided with groove, expand ureter inwall and ureter bracket it
Between space, beneficially the scattering and discharge of calculus, reduce the incidence rate in stone street, improve calculus clearance rate,
Decrease ureter bracket and ureteral contact surface simultaneously, reduce the complication of ureter wall damage.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of the linear type odd-shaped cross section ureter bracket of the present invention.
Accompanying drawing 2 is the partial schematic diagram of the linear type odd-shaped cross section ureter bracket end of the present invention.
Accompanying drawing 3 is the schematic diagram of the screw type odd-shaped cross section ureter bracket of the present invention.
Accompanying drawing 4 is the partial schematic diagram of the screw type odd-shaped cross section ureter bracket end of the present invention.
Detailed description of the invention
The detailed description of the invention provided the present invention below in conjunction with the accompanying drawings elaborates.
The reference and the ingredient that relate in accompanying drawing are as follows:
1. ureter bracket 11. groove
12. conduction holes.
Embodiment
Refer to the schematic diagram that Fig. 1 and Fig. 2, Fig. 1 are the linear type odd-shaped cross section ureter brackets of the present invention,
Fig. 2 is the partial schematic diagram of the linear type odd-shaped cross section ureter bracket end of the present invention.Described ureter
Support 1 is hollow tubular structure, the two ends of ureter bracket 1 each looped-shaped bending, ureter bracket 1
Tube wall be provided with groove 11 and conduction hole 12, described groove 11 is provided with 3, is arranged in a linear, institute
The ureter bracket 1 stated is prismatic.
Refer to the schematic diagram that Fig. 3 and Fig. 4, Fig. 3 are the screw type odd-shaped cross section ureter brackets of the present invention,
Fig. 4 is the partial schematic diagram of the screw type odd-shaped cross section ureter bracket end of the present invention.Described ureter
Support 1 is hollow tubular structure, the two ends of ureter bracket 1 each looped-shaped bending, ureter bracket 1
Tube wall be provided with groove 11 and conduction hole 12, described groove 11 is provided with 3, arranges in the shape of a spiral,
Described ureter bracket 1 is prismatic.
After ureter bracket 1 is inserted in the patient, the groove 11 on ureter bracket 1 tube wall expands
Scattering and discharging of space between ureter inwall and ureter bracket 1, beneficially calculus, reduces stone
The incidence rate in street, improves calculus clearance rate, decreases ureter bracket 1 and ureteral contact surface simultaneously,
Reduce the complication of ureter wall damage.
The above is only the preferred embodiment of the present invention, it is noted that common for the art
Technical staff, on the premise of without departing from the inventive method, it is also possible to makes some improvement and supplements, these
Improve and supplement and also should be regarded as protection scope of the present invention.
Claims (4)
1. an odd-shaped cross section ureter bracket, it is characterised in that described ureter bracket is hollow tubular
