Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a balloon dilation catheter.
Background
A balloon dilation catheter is a medical intervention device, and has the main functions of pneumothorax and unstable hemoptysis related responsible bronchus blocking treatment. Publication number CN113289209A discloses sacculus inflation catheter, including sacculus, the expansion pipe, pipe seat and seal wire, the expansion pipe includes seal wire pipe and sacculus gas tube, the pipe seat includes into silk pipe seat and air inlet pipe, it is connected with the one end of seal wire pipe to advance silk pipe seat, the one end of air inlet pipe seat and sacculus gas tube is connected, the seal wire wears to establish in the seal wire pipe, the seal wire pipe is all extended at the both ends of seal wire, the other end of seal wire pipe and sacculus gas tube all stretches into in the sacculus, the surface of the inside sacculus gas tube of lies in the sacculus evenly is provided with the inflation inlet along length direction, the inflation inlet evenly inflates the sacculus. The invention utilizes the expansion tube to respectively install the wire guide tube and the balloon inflation tube, and the surface of the tail end of the balloon inflation tube is provided with the uniform inflation port so as to achieve the purpose of uniform compression, reduce the compression dangerous coefficient and solve the technical problem of nonuniform inflation of the current balloon.
However, the balloon and the dilating tube are integrated, and after the balloon is inserted into the responsible bronchus, the balloon and the dilating tube cannot be separated, and the dilating tube is still placed in the responsible bronchus and needs to be left for a long time, which can cause discomfort to a patient and even serious complications, and is unfavorable for the prognosis of pneumothorax and unstable hemoptysis. There is a need for improvements over existing balloon dilation catheters.
Furthermore, refractory pneumothorax is a common and troublesome clinical problem, the disease course of which is prolonged, the life quality of patients is seriously affected, and complications such as secondary infection, respiratory failure and the like can sometimes occur, and even life is endangered. The selective bronchoballoon occlusion is a safe, suitable and economical refractory pneumothorax and unstable hemoptysis for selective bronchoocclusion, but the balloon and the airway are irremovable, and have complications which are difficult to avoid.
Disclosure of Invention
The invention aims at solving the technical problems that a balloon and an air duct are not detachable and complications which are difficult to avoid exist in the selective bronchus balloon plugging operation, and provides a balloon dilation catheter which is used for controlling pneumothorax or unstable hemoptysis after the balloon is inserted into a responsible bronchus and then separating the balloon from the air duct, so that the air duct is extracted out of a human body, discomfort and complications of a patient are avoided, and pain of the patient is greatly improved.
In order to achieve the above purpose, the invention adopts the technical scheme that: the balloon dilation catheter comprises an inflation tube seat, an inflation tube and a balloon, wherein the inflation tube is movably connected with the balloon.
Preferably, an air duct is arranged in the saccule, and a plurality of inflation openings are formed in the air duct; the front end of the saccule is provided with a connector, and the air duct is connected with the connector; a one-way valve and a connecting ring are arranged in the connector; the inside of the inflation tube is provided with a conduit and a stay wire, the end part of the inflation tube is provided with a conical bulge and an umbrella-shaped elastic connecting sheet, the end part of the connecting sheet is provided with a buckle, and the buckle is connected with the stay wire.
Preferably, the buckle is provided with a through hole, the buckles are connected into a ring shape through coils, and the coils are connected with the stay wire.
Preferably, the end of the connector is provided with a flexible guide ring.
Preferably, a limiting ring is arranged at the inlet of the connecting ring.
Preferably, the outer side of the end part of the inflation tube is provided with an inflation sealing ring, and a plurality of inflation holes are formed in the wall of the inflation tube in the inflation sealing ring.
The invention has the following beneficial effects:
(1) Firstly, a lead is inserted into a conduit, an umbrella-shaped elastic connecting sheet and a buckle can be folded through a pull wire, so that the end part of the air duct is smaller, and then the air duct is inserted into a connector of the saccule. When the buckle enters the connecting ring in the connector, the stay wire is loosened, and the umbrella-shaped elastic connecting sheet is dispersed under the action of the elastic force of the umbrella-shaped elastic connecting sheet, so that the connection between the air duct and the balloon is realized. The end part of the connector is provided with the wide-mouth flexible guide ring, the wide-mouth flexible guide ring is in an open state under a normal state, so that the air duct is convenient to insert, and meanwhile, the wide-mouth flexible guide ring is made of flexible materials, is easy to move and does not hurt the human air duct.
(2) Then the balloon is sent into the patient's bronchus, and then the balloon is inflated from the inflation port of the inflation tube seat, and the inflated balloon seals the patient's bronchus. In the process of inflation, gas can also enter the inflatable sealing ring at the end part of the air duct through the inflation hole, so that the inflatable sealing ring is inflated, and the inflated inflatable sealing ring forms a seal with the connecting port of the balloon connector, so that the inflation effect can be improved. When the inflation is stopped, firstly, the gas in the inflation sealing ring is discharged through the inflation hole, and then the umbrella-shaped elastic connecting sheet is folded through the stay wire, so that the gas-guide tube is separated from the balloon connector, and the gas-guide tube is pulled out of the human body. Because the connector of the saccule is internally provided with a one-way air valve similar to inflation of basketball and tires. After the air duct is pulled out of the human body, the balloon filled with air can not leak air, and the balloon always keeps an inflated state and is kept in the responsible bronchus for continuous blocking.
(3) When the balloon is required to be taken out from the responsible bronchus, the umbrella-shaped elastic connecting sheet is firstly folded through the stay wire, so that the end part of the air duct is reduced, then the air duct is inserted into the balloon connector through the wide-mouth flexible guide ring, and when the buckle enters the connecting ring in the connector, the stay wire is loosened, and the umbrella-shaped elastic connecting sheet is dispersed under the action of the self elastic force, so that the connection between the air duct and the balloon is realized. After connection is achieved, the air duct is pushed inwards continuously, when the umbrella-shaped connecting sheet 6 is positioned at the innermost end of the connecting ring 5, the conical bulge at the end part of the air duct can push the one-way air valve open, and air in the balloon is discharged, so that the balloon is reduced. The airway together with the balloon is then pulled out of the responsible bronchi.
