Abstract

The utility model is composed of a pipe which is made of medical high-molecular material, both ends of the pipe are bent inwards in opposite directions to form a circular shape like a pigtail, 3 to 5 side holes are arranged on the pipe walls of both ends which are bent into the circular shape, the diameter of each side hole is from 0.1 to 0.8 mm, the middle section of the pipe is provided with 10 to 20 inflated small baskets in a bead string shape, four openings are equally opened on the walls of the circumference of the pipe, the lower end of the pipe is provided with a bladder marking point of a ureter, and the upper end is provided with a kidney marking point, and the upmost end of the pipe is in a tapered conical pipe shape. Owing to the special small baskets which are in bead string shapes and can be inflated and shrunk, compared with the prior single stone sheathing basket, the success ratio for tacking stones is greatly increased, and the phenomenon that the stone is sheathed and then is shed can not occur. The pipe has a whole range bead string structure and has good supporting function for the ureter, the ureter can not be blocked by the stone, and urine in the kidney can smoothly reach the bladder.

Description

A kind of urinary system stone taking device

Technical field

This utility model belongs to the surgical operation auxiliary material, a kind of specifically Urology Surgery stone taking device.

Background technology

Urinary system calculus is the common disease of Urology Surgery, frequently-occurring disease; and main Therapeutic Method is a rubble under extracorporeal shock-wave lithotomy and the ureteroscope at present; being difficult for nature by the calculus after pulverizing discharges; existing stone taking device has only a calculus catching net-like means; the stone that takes out is limited; repeatable operation can increase patient's misery, also calculus occurs by the phenomenon that comes off again after entangling through regular meeting, and can not play the effect of support to ureter.

The utility model content

The purpose of this utility model is to solve above-mentioned deficiency, provides a kind of simple to operate, gets stone success rate height and can also support ureteral urinary system stone taking device.

For achieving the above object, this utility model is made up of the pipe of being made by medical macromolecular materials, the two ends of pipe rightabout each other bend to the circle shape inwardly, shape such as pigtail, bending on the two ends tube wall of circle shape has some side openings, the corbeil that the stage casing of pipe has beading to expand, and there is the tubal bladder gauge point lower end of pipe, there is the kidney gauge point upper end of pipe, and the top of pipe is gradually thin tapered tubular; The caliber of pipe is 2.2-2.8mm, and length is 190-290mm; Bending on the two ends tube wall of circle shape has 3-5 side opening, and diameter is 0.1-0.8mm; The corbeil that the pipe stage casing has 10-20 beading to expand is that wall is first-class around pipe to be opened four opennings and makes, and its diameter is 3-6mm under the normal condition, and length is 7-10mm, expands that its diameter is 7-10mm under the state, and length is 4-7mm.

Adopt said structure,, improved the success rate of getting stone greatly, the phenomenon that comes off again after calculus is entangled can not occur than existing single calculus catching net-like means because its special beading can expand contractile corbeil; The omnidistance beading structure of this utility model plays good supporting role to ureter, and ureter can not blocked by calculus, and urine can reach bladder smoothly in the kidney.

The specific embodiment

This utility model is made up of the pipe of being made by medical macromolecular materials, the two ends of pipe rightabout each other bend to the circle shape inwardly, shape such as pigtail, bend to some side openings not 1 are arranged on the two ends tube wall of circle shape, the corbeil 2 that the stage casing of pipe has beading to expand, there is tubal bladder gauge point 3 lower end of pipe, and there is kidney gauge point 4 upper end of pipe, and the top of pipe is gradually thin tapered tubular 5; The caliber of pipe is 2.2-2.8mm, and length is 190-290mm; Bending on the two ends tube wall of circle shape has 3-5 side opening, and diameter is 0.1-0.8mm; The corbeil that the pipe stage casing has 10-20 beading to expand is that wall is first-class around pipe to be opened four opennings and makes, and its diameter is 3-6mm under the normal condition, and length is 7-10mm, expands that its diameter is 7-10mm under the state, and length is 4-7mm.

Claims
