Description

Prevent air bag of getting stone of stone omission

Technical Field

The utility model relates to the field of medical equipment, more specifically says, relates to a prevent getting stone gasbag that stone was omitted.

Background

Patients with choledocholithiasis, hepatodochus, and left and right hepatolithes often have abdominal pain, obstructive jaundice, and fever. At present, therapeutic ERCP (bile duct stone removal treatment through duodenoscope) is the first choice for patients who do not want to do surgery, have contraindications of surgery, relapse after surgery, cholecystectomy and the like, and the adopted calculus removing air bag consists of an outer tube body of the calculus removing air bag, an air bag connected with the outer tube body, an inflating handle and a contrast agent injection handle. In the process of removing calculus from bile duct, firstly, the choledochoscope is used for retrograde cholangiography to know the specific position, size and number of calculus, then the balloon dilatation under the duodenoscope or papillary sphincter incision is carried out, and the extrahepatic bile duct calculus is dragged out by adopting the calculus removing balloon.

In the process of taking out the calculus, although a doctor can take out the calculus by inflating the calculus taking air bag, the calculus can be taken out by the shape change of the inflated existing calculus taking air bag, the calculus taking air bag can not guarantee that all the calculus can be taken out at one time when the calculus is relatively stubborn, the calculus needs to be taken out by dragging the calculus taking air bag in a patient pipeline for multiple times, and the patient pipeline is easily and carelessly injured due to the fact that the calculus taking air bag is filled in the pipeline and the calculus is dragged.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, the utility model aims to provide a prevent calculus removal gasbag that calculus was omitted, it is through the calculus removal portion of establishhing the indent on the calculus removal gasbag to make calculus removal portion still keep the state of indent after calculus removal gasbag inflation, from this in the calculus removal gasbag fills the bile duct and under the shape influence of calculus removal portion, calculus removal portion collects and takes out the stubborn calculus of adhering to on the pipe wall more easily.

In order to solve the above problems, the utility model adopts the following technical proposal.

An anti-missing calculus removing air bag comprises an operating handle, a conduit, an inflating handle and a calculus removing air bag; the catheter is connected in the operating handle, and one end of the catheter extends outwards from the operating handle; one end of the inflating handle is communicated with the outer wall of the guide pipe through a connecting pipeline, an air guide channel is communicated between the connecting pipeline and the outer wall of the guide pipe, and the air guide channel extends to be communicated with the calculus removing air bag; the calculus removing air bag is arranged on the outer surface of the catheter far away from the operating handle, the interior of the calculus removing air bag is conical before being inflated, the axial direction of the calculus removing air bag is flush with the axial direction of the catheter, and a calculus removing part is recessed in one end of the calculus removing air bag close to the operating handle; the concave part of the stone removing part and the outer surface of the stone removing air bag are S-shaped; after the inflation handle is inflated, the air can be guided to the interior of the calculus removing air bag through the air guide channel to expand the calculus removing air bag, so that the calculus removing part still keeps concave and expands outwards to enlarge the calculus removing range to be in a calculus removing state.

Furthermore, the inflation handle is provided with a switch valve, and the switch valve can change the state of the air guide channel in a closed or open state when rotating.

Furthermore, the stone-taking air bag is made of plastic; the stone taking part has certain hardness so that the stone taking part can firmly clamp the stone when being pushed in a stone taking state, and the problem that stubborn stones in the pipeline cannot be separated is avoided.

Furthermore, the other end of the catheter extends outwards from the inside of the operation handle and is communicated with a guide handle, and the guide handle and the catheter are used for extending into the guide wire; an injection handle which is parallel to the inflation handle and the guide handle is arranged outside the operating handle, one end of the injection handle is communicated with an injection pipeline, the injection pipeline is communicated with the outer wall of the catheter and internally provided with an injection channel which is not communicated with the air guide channel, one end of the injection channel extends to the outer surface close to the tail end of the catheter and is provided with an injection hole, and the injection handle is used for injecting contrast medium and water.

Further, the side end wall of the catheter, which is far away from the operating handle and close to the calculus removing air bag, is arc-shaped.

Further, the maximum circumference diameter of the contact space after the stone removing part is expanded is at least twice larger than the diameter of the conduit.

Compared with the prior art, the utility model has the advantages of:

one, this scheme is through establishing the stone portion of getting of indent on getting the stone gasbag to make the stone portion of getting still keep the state of indent after getting the stone gasbag inflation, in the bile duct and getting the shape influence of stone portion are filled to the bag of getting from this, get the stone portion and collect and take out the calculus that stubborn attached to on the pipe wall more easily.

Because get stone portion and be interior concavity in this scheme, when it enlarges and gets the stone scope, get stone portion and accomplish more easily when dragging the pipe, play the effect of collecting and take out the quick effectual whole of calculus in the bile duct with this, accomplish once only as far as possible and all take out the calculus with this reduction cause the unnecessary injury to the patient.

And thirdly, the tail end of the catheter in the scheme is arc-shaped, so that the injury and damage to the wall of the patient tube can be avoided as far as possible when the catheter extends into the bile duct.
