Abstract

The utility model discloses a medical air bag type stone extraction guide tube, which is mainly used for retained calculus after ureteral calculus and common bile duct operations. The utility model is composed of an air bag, a cavity body and a metal guide wire; the utility model has two forms of single cavity single bag and double cavity double bag; a side hole air through bag is arranged on the wall of the tube; the side hole air through bag can inject air (water) for the air bag; the guide wire is arranged in the cavity to prevent the guide tube curling. The utility model has the advantages of simple structure, low cost, convenient use, easy operation and good stone extraction effect, avoiding the pain of bodies and unnecessary economic burden which are brought by operations for patients. The utility model permits multiple operation and avoids multiple operations according to the characteristic of the easy recurrence of the ureteral calculus.

Description

Medical gasbag-type is got the stone conduit

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of gasbag-type ureter or choledocholithiasis withdrawing device.

Therapeutic Method to ureteral calculus has following four kinds at present: (1) operative treatment (2) rubble (3) ureteroscope is got stone (4) calculus dissolving and excreting, the operative treatment patient suffers painful big, the expense height, because it is due to patient's endogenous cause of ill that calculus forms great majority, so postoperative easily recurs, the need that have are repeatedly performed the operation, and disease is sent out in operation itself, and postoperative ureter otch scar contracture causes stricture of ureter.Patient has certain misery when adopting lithotripsy method, can cause the visceral injury complication, and the rubble row who can have and still need perform the operation, and expense is big.Adopt scope (ureteroscope) to get stone, scope manufacture technology complexity, the expense height, what have needs import, and at present domestic only have the minority large hospital just to have.And the calculus dissolving and excreting weak effect.Have (1) operation, (2) ten two to refer to that mirror cuts (EST) down and gets stone, (3) calculus, lithodialysis to common bile duct retained calculus (band T pipe) Therapeutic Method at present, wherein surgical patient is painful big, the expense height.Choledochoscope manufacture technology complexity, the buying expenses height.The need dependence on import that has is restricted so use.Adopt the recent complication of EST operation to have: incision wound bleeding, cholelithiasis incarceration cause the obstructive cholangitis of acute festering type, need emergency operation, otch to cause the perforation of 20 duodenum 12 excessively deeply; Long term complication has that otch is excessive to be caused 12 the fat intestinal contents is counter flowing.

The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple in structure, and gasbag-type ureter and common bile duct that expense is low, effective are got the stone conduit.

This utility model is made of air bag, cavity and wire guide, divide single chamber and two kinds of forms of two-chamber, have side opening ventilation capsule on the tube wall, can be to air bag gas injection (water), intracavity is provided with wire guide, when the seal wire purpose is to insert ureter or common bile duct in case conduit curl, during use with air bag not the stone conduit of getting of gas injection insert ureter or common bile duct, after air bag is crossed calculus, transfer to seal wire to air bag gas injection (water), make catheter tip expansion back calculus is pulled to easy processing place by pull catheter.

70-80 centimetre of conduit total length of the present utility model, caliber can be the 1.5-3 millimeter.

This utility model is simple in structure, cost is low, easy to use, easy to operate, it is effective to get stone, avoids performing the operation and brings sensual pain and unnecessary financial burden to patient, is difficult for the recurrence characteristics according to ureteral calculus, but multi-pass operation is repeatedly performed the operation avoiding.

Accompanying drawing 1: be embodiment 1 structural representation

Accompanying drawing 2: be embodiment 2 structural representations

Contrasting accompanying drawing below in conjunction with embodiment is elaborated to this utility model.

Embodiment 1

Present embodiment is single cavity single-bag formula, constitute by air bag, cavity and wire guide, cavity is that the tube wall of endcapped is provided with graduated conduit 1, be provided with the wire guide 3 that can insert or transfer in its tube chamber, terminal sidewall has side opening 4 ventilation capsules 2, conduit 1 is made of plastics, 80 centimetres of total lengths, and caliber is 1.5 millimeter.Embodiment 2

The two cavity single-bag formulas of this utility model, by air bag, cavity and wire guide constitute, the dual chamber of cavity for being made of inner and outer pipe 1,7, outer tube 1 tube wall is provided with scale, end is provided with air bag 2, and tube wall has side opening 4 ventilation capsules 2, and head end is provided with gas injection (water) mouth 5, be provided with wire guide 3 in interior pipe 7 tube chambers, endcapped is also given prominence to outer tube 1, and have side opening 6 at the sidewall that protrudes in outer tube 1, so that wire guide transfers to the back to inject contrast agent.

When utilizing this utility model to get ureteral calculus, under assisting, cystoscope inserting ureter under the radiography X line, through after the calculus, inflation, by the wire guide pull catheter calculus is drawn in intravesical or ureter in the bladder opening part, after cystoscope was stung the stone pincers and bitten into pieces, per urethra was discharged.

When utilizing this utility model to get common bile duct postoperative residue calculus (band T pipe), behind T pipe radiography, under the X line, insert; Inflate after crossing calculus, pull catheter is pulled to the T mouth of pipe with calculus, takes out or clamps with lithotomy forceps and brokenly draw through the T pipe.
