Abstract
The utility model relates to a dilator, in particular to a pylorodilator, which comprises a catheter, a balloon, a water injection inlet, an anti-leakage valve and a support steel wire inlet; wherein the length of the catheter is 20 cm to 35 cm, and the diameter of the balloon is 2 to 4 cm. The utility model has the advantages of that: (1) Replacing the pyloroplasty with the balloon dilation not only can relieve the pylorospasm, but also can reserve the function of that pyloric sphincter resists the backward flow of the bile, which avoids the pollution, inconvenience, injury and poor effect caused by hands or other nonspecific tools. (2) Simplifying and facilitating the surgical operation, reducing the injury and pollution, avoiding the postoperative complication, and ensuring the therapeutic effect. (3) The dilation range of the balloon is changeable with the different degree of the balloon; the hardness of the balloon conveying rod is changeable with the drawing-off of the support steel wire in the balloon conveying rod; the balloon with the anti-leakage valve can keep the balloon in a filled state; the small bulge on the surface of the balloon makes the balloon easily fixed in the pylorus.
Description
Technical field
This utility model relates to a kind of dilator, specifically about a kind of pylorodilator.
Background technology
Pylorospasm can appear in esophagus and cardia postoperative part patient makes gastric emptying disorder, people's postoperative not to take food, therefore the conventional pylorus urethroptasty of doing in " three cuts " esophagus resection operation and cardia operation to be preventing pylorospasm, and this operation is more time-consuming, the possibility that causes local fistula is still arranged.And the pylorus urethroptasty has destroyed sphincter of pylorus fully, and postoperative bile reflux gastritis can occur bar none, brings great misery to patient.The expansion of in the art sphincter of pylorus of spasm being carried out appropriateness can reach the effect of not only removing pylorospasm but also keeping the anti-bile reflux of sphincter of pylorus, but still there is not special-purpose pylorodilator at present, effect is undesirable, use is inconvenient to substitute (as uterine dilator etc.) with other utensils, expand easy contaminated operation open country and damage gastric mucosa, tunica muscularis gastris with hands, therefore, be necessary pylorus extension fixture special-purpose in a kind of art of utility model.
In clinical practice, we once expanded pylorus with esophageal dilator, but the conduit of esophageal dilator is oversize, and were not easy to operate; Sacculus is too little, is difficult for the expansion pylorus.
Chinese patent provides a kind of sacculus elastic hose esophageal dilator for No. 92211729.2, this dilator is the sebific duct of blunt garden shape by an end, the needle stand of sacculus, conduit and catheter tip is formed, this sacculus elastic hose esophageal dilator is a kind of new type medical equipment for treatment achalasia of the cardia in the interventional radiology, but can not expand with pylorus in the Rhizoma Atractylodis Macrocephalae.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, is convenient to make the pylorodilator of using in the respond well art.
The purpose of this utility model realizes by following technical method: the pylorodilator of using in a kind of art, comprise conduit, and sacculus, the water filling inlet, the anti-valve that leaks, leaks gas, the supporting steel wire inlet, wherein catheter length is 20cm-35cm.Catheter length is preferably 25cm.Balloon diameter is 2-4cm.Balloon diameter is preferably 3cm.Balloon surface is provided with small embossment.This utility model also comprises supporting steel wire.Supporting steel wire enters conduit by the supporting steel wire inlet.
The pylorodilator of using in the disclosed a kind of art of this utility model, its advantage shows:
(1) substitutes the pylorus molding with balloon expandable and can remove the function that pylorospasm has kept the anti-bile reflux of sphincter of pylorus again, avoided the pollution, inconvenience, damage and the poor effect that cause with hands or other non-specific purpose tools.
(2) simplify, made things convenient for operation technique, reduced surgical injury and pollution, prevent postoperative complication, guarantee therapeutic effect.
(3) scope of balloon expandable is variable with the degree difference of sacculus; Whether variable the hardness of sacculus conveying lever is with the extraction of the supporting steel wire in it; Sacculus has the anti-valve that leaks, leaks gas, and can keep sacculus in full state; The small embossment of balloon surface makes it easily be fixed in the pylorus place.
