Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a balloon dilatation catheter.
Background
A balloon dilatation catheter is a medical intervention device and mainly has the functions of pneumothorax and unstable hemoptysis related liability bronchus blocking treatment. Publication number is CN113289209A discloses sacculus expansion pipe, including the sacculus, the expansion pipe, pipe seat and seal wire, the expansion pipe includes wire guide pipe and sacculus gas tube, the pipe seat is including advancing wire pipe seat and air inlet pipe, it is connected with the one end of wire guide pipe to advance the wire pipe seat, the one end of air inlet pipe seat and sacculus gas tube is connected, the seal wire is worn to establish in the wire guide pipe, the wire guide pipe all extends at the both ends of seal wire, the other end of wire guide pipe and sacculus gas tube all stretches into to the sacculus, the surface that is located the inside sacculus gas tube of sacculus evenly is provided with the inflation inlet along length direction, the inflation inlet is even aerifys 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 risk coefficient of compression and solve the technical problem of nonuniform balloon inflation at present.
However, the balloon and the dilating tube are integrated, so that after the balloon is inserted into the responsible bronchus, the balloon and the dilating tube cannot be separated, the dilating tube is still arranged in the responsible bronchus and needs to be kept for a long time, which causes discomfort to the patient and even serious complications and is not favorable for the prognosis of pneumothorax and unstable hemoptysis. There is a need for improvements to existing balloon dilation catheters.
In other words, the intractable pneumothorax is a common and intractable clinical problem, the course of the disease is prolonged, the life quality of the patient is seriously affected, and sometimes complications such as secondary infection, respiratory failure and the like can occur, even the life is threatened. The selective bronchial balloon occlusion is a safe, proper and economical selective bronchial occlusion performed by refractory pneumothorax and unstable hemoptysis, but the balloon and the airway are not detachable, and complications which are difficult to avoid exist.
Disclosure of Invention
The invention aims to solve the technical problems that a balloon and an air duct are not detachable and have difficult-to-avoid complications in selective bronchial balloon occlusion, and provides a balloon dilatation catheter.
In order to achieve the purpose, the invention adopts the technical scheme that: a balloon dilatation 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 balloon, and a plurality of inflation ports are formed in the air duct; the front end of the balloon 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; be provided with the conduit in the gas tube and act as go-between, the tip of gas tube has the taper arch and has umbelliform elastic connection piece, and the tip of connection piece has the buckle, and the buckle is connected with acting as go-between.
Preferably, the buckle is provided with a through hole, the plurality of buckles are connected into a ring shape through a coil, and the coil is connected with the pull wire.
Preferably, the end of the connecting head is provided with a flexible guide ring.
Preferably, a limiting ring is arranged at the inlet of the connecting ring.
Preferably, the end of the inflation tube is provided with an inflation sealing ring, and the wall of the inflation tube in the inflation sealing ring is provided with a plurality of inflation holes.
The invention has the following beneficial effects:
(1) Insert the wire into the conduit earlier, can let umbelliform elastic connection piece and buckle draw in through acting as go-between, make the air duct tip diminish, then insert in the connector of sacculus. When the buckle enters the connecting ring in the connector, the stay wire is loosened, and the umbrella-shaped elastic connecting piece is scattered under the action of the elastic force of the umbrella-shaped elastic connecting piece, so that the connection of the air duct and the balloon is realized. The tip at the connector is provided with wide-mouth flexible guide ring, and the wide-mouth flexible guide ring is the state of opening under the normal condition, and the air duct of being convenient for inserts, simultaneously because wide-mouth flexible guide ring adopts the flexible material preparation, removes easily and can not harm human trachea.
(2) Then the saccule is sent into the patient responsible bronchus, and then the saccule is inflated from the inflation port of the inflation tube seat, and the inflated saccule seals the patient responsible bronchus. In the process of inflation, gas can enter the inflation sealing ring at the end part of the gas guide tube through the inflation hole, so that the inflation sealing ring expands, and the expanded inflation sealing ring forms sealing with a connecting port of the balloon connector, thereby improving the inflation effect. When the inflation is stopped, the gas in the inflation sealing ring is discharged through the inflation hole, and then the umbrella-shaped elastic connecting piece is folded through the pull wire, so that the air guide tube is separated from the balloon connector, and the air guide tube is pulled out of the human body. Because the connector of the sacculus is internally provided with a one-way air valve similar to the inflation of a basketball and a tire. After the air duct is pulled out of a human body, the balloon filled with air cannot leak air, is kept in an inflated state all the time, and is kept in a responsible bronchus for continuous plugging.
(3) When the balloon needs to be taken out of the responsible bronchus, the umbrella-shaped elastic connecting piece is firstly folded by the stay wire to enable the end part of the air duct to be reduced, then the air duct is inserted into the balloon connector through the wide-mouth flexible guide ring, when the buckle enters the connecting ring in the connector, the stay wire is loosened, and the umbrella-shaped elastic connecting piece is scattered under the action of the elastic force of the buckle, so that the connection of the air duct and the balloon is realized. After the connection is realized, the air duct is continuously pushed inwards, and when the umbrella-shaped connecting piece 6 is positioned at the innermost end of the connecting ring 5, the conical bulge at the end part of the air duct can jack the one-way air valve to discharge the air in the balloon, so that the balloon becomes small. The airway and balloon are then pulled out of the culprit bronchus together.
