Description

Novel sacculus expander

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a novel balloon dilator.

Background

The narrow obstruction of human body cavity (such as esophagus, biliary tract and intestinal tract) caused by various pathological changes needs to be treated by balloon dilatation, and the treatment route is usually completed under an endoscope.

The balloon of the balloon dilator used at present is football-shaped, when in use, the middle part of the balloon is placed at a narrow part, and the balloon is inflated by air injection or water injection to dilate a narrow digestive tract and the like. However, displacement of the balloon often occurs during use, so that the middle part of the balloon is not in the narrow part and cannot achieve the ideal expansion effect.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a novel balloon dilator to solve the problems set forth in the background art.

In order to achieve the purpose, the utility model provides the following technical scheme:

a novel balloon dilator comprises an insertion tube, wherein one end of the insertion tube is provided with a dilating component, the end part of the insertion tube penetrates through the dilating component and extends to the outer side of the dilating component, the dilating component consists of a first balloon and a second balloon, and the side wall of the insertion tube is provided with a first gas injection cavity and a second gas injection cavity which are distributed oppositely and used for injecting gas into the first balloon and the second balloon respectively;

the both sides of first sacculus all are provided with the recess, the recess forms "worker" type structure with first sacculus, and through the setting of recess, when the gas injection to first sacculus, first sacculus expansion for groove is located alimentary canal narrow and narrow department, thereby can prevent effectively that expansion assembly from shifting.

As a further scheme of the utility model: the first sacculus is arranged on the outer side of the intubation tube and is fixedly connected with the intubation tube, and the first sacculus is conveniently extended to the narrow part of the alimentary canal through the intubation tube by fixedly connecting the first sacculus with the outer side wall of the intubation tube.

As a still further scheme of the utility model: the second sacculus distributes on the both sides wall of first sacculus to with first sacculus fixed connection, through the setting of second sacculus, when gas injection to the second sacculus, the expansion of second sacculus, thereby expand the narrow department of alimentary canal.

As a still further scheme of the utility model: the first gas injection intracavity is provided with the first gas injection pipe that is linked together with first sacculus, the second gas injection intracavity is provided with the second gas injection pipe that is linked together with the second sacculus, through to first outlet duct gas injection, carries out the gas injection to first sacculus, through to the gas injection of second gas injection pipe, carries out the gas injection to the second sacculus.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, through the matching between the first balloon and the second balloon, the balloon is limited under the action of the groove of the first balloon, so that the phenomenon of balloon displacement can be effectively prevented, and the digestive tract stricture is effectively expanded under the action of the second balloon, so that the expansion effect is good, and the use is convenient.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, in an embodiment of the present invention, a novel balloon dilator includes an insertion tube 1, an expansion assembly is disposed at one end of the insertion tube 1, an end of the insertion tube 1 penetrates through the expansion assembly and extends to an outer side of the expansion assembly, the expansion assembly is composed of a first balloon 2 and a second balloon 3, and two first air injection cavities 5 and second air injection cavities 6, which are distributed oppositely and used for injecting air into the first balloon 2 and the second balloon 3, are disposed on a side wall of the insertion tube 1.

The first balloon 2 is arranged on the outer side of the cannula 1 and is fixedly connected with the cannula.

By fixedly connecting the first balloon 2 with the outer side wall of the cannula 1, the first balloon 2 can be conveniently extended to the narrow part of the alimentary canal through the cannula 1.

Grooves 4 are formed in two sides of the first balloon 2, and the first balloon 2 is formed into an I-shaped structure through the grooves 4.

Through the setting of recess 4, when inflating first sacculus 2, first sacculus 2 expands for recess 4 is located the narrow department of alimentary canal, thereby can effectively prevent the displacement of expansion subassembly.

The second sacculus 3 is distributed on two side walls of the first sacculus 2 and is fixedly connected with the first sacculus 2.

With the provision of the second balloon 3, when the gas is injected into the second balloon 3, the second balloon 3 is expanded, thereby expanding the stricture of the digestive tract.

A first air injection pipe communicated with the first balloon 2 is arranged in the first air injection cavity 5, and a second air injection pipe communicated with the second balloon 3 is arranged in the second air injection cavity 6.

Through to first outlet duct gas injection, carry out the gas injection to first sacculus 2, through to the gas injection of second gas injection pipe, carry out the gas injection to second sacculus 3.
