The utility model relates to a cardia expansion balloon.

Background technique

The cardia is a part of the digestive tract of humans or animals. It is the interface between the esophagus and the stomach. It is the entrance to the upper end of the stomach. The food in the esophagus enters the stomach through the cardia.

The traditional cardia expansion balloon, as shown in Figure 1, is made of a polyethylene rigid cardia balloon 11 and a catheter 12, the balloon 11 is cylindrical, coaxially installed at one end of the catheter 12, and the catheter 12 Endoscopically passable guide wire. The process of placing the cardia dilatation balloon is generally as follows: under the guidance of the endoscope, the balloon 11 is positioned at the cardia (the endoscope and the balloon 11 enter the human body together), as shown in Figure 1, and then gradually inflated, Until the thin waist stenosis of cylindrical balloon 11 becomes flat.

After the traditional cardia dilatation balloon is positioned, because the position cannot be fixed, the actual expansion position of the balloon is often unclear during expansion, and the pertinence is not enough. This situation is more likely to occur in patients with long-term achalasia due to structural changes in their esophagus, which is not conducive to their treatment.

Three-lumen two-bag tube, including three-lumen tube, gastric balloon and esophageal balloon, the gastric balloon and esophageal balloon are attached to one end of the three-lumen tube, and the three-lumen tube consists of a semicircular lumen and two quarter-section The gastric balloon catheter and the esophageal balloon catheter are respectively installed in two quarter-circular lumens, and the gastric catheter is installed in a semicircular lumen. The cross-section of the gastric catheter is semicircular, and its outer wall is in sealing fit with the inner wall of the semicircular cavity, and the gastric catheter can move in the semicircular cavity. The three-lumen two-capsule catheter is mainly used for compression and hemostasis in patients with massive bleeding from esophageal and gastric fundus varices.

The three-chamber two-capsule tube is a soft latex tube. When in use, it is put into the nasal cavity of the patient, the gastric balloon enters the stomach, and the esophageal balloon is located in the esophagus. Good positioning of the esophageal balloon in the esophagus. If the gastric air bag ruptures, the catheter may slide up and block the throat, causing severe dyspnea or even suffocation. Once the above situation occurs, the two air bags should be quickly deflated and the three-chamber two-bag catheter should be pulled out.

The utility model combines the traditional cardia expansion balloon with three-chamber two-capsule tube, and aims to provide a fixed cardia expansion balloon to provide safety assurance, so as to effectively and accurately expand the lower cardia sphincter and shorten the operation time. Reduce surgical complications.

The new model can also achieve blind expansion.

The purpose of the invention of the utility model is achieved through the following technical scheme: a kind of fixed cardia expansion balloon, including a hard cardia balloon for expanding the cardia and a catheter that can pass through the guide wire, and the cardia balloon is installed on the One end of the catheter communicates with the cardiac balloon inflation pipeline arranged along the catheter, and it is characterized in that the cardiac dilation balloon also includes a location for positioning in the stomach and preventing the cardiac dilation balloon from shifting. A balloon, the positioning balloon and the cardia balloon are installed at the same end of the catheter, closer to the end of the catheter, and a positioning balloon inflation pipeline is also provided along the catheter, the positioning The balloon communicates with the positioning balloon inflation pipeline.

After completing the positioning of the guide wire through the endoscope, the endoscope is taken out, and then guided by the guide wire, the cardia expansion balloon of the present utility model is placed in the corresponding position, and the positioning balloon and the cardia balloon of the present utility model are inflated to make the positioning ball The top of the capsule is below the entrance of the upper end of the stomach to fix the lower end of the cardia balloon. At this time, the cardia balloon is just positioned at the cardia. Since the upper end of the cardia balloon is also positioned, the cardia balloon can accurately target the lower esophageal sphincter. to expand.

As improvement of the utility model:

The positioning balloon is a self-explosive balloon, and the self-explosive balloon will self-explode when pressure changes through the cardia in an inflated state.

As a preferred embodiment of the present utility model:

The recommended volume of the self-exploding balloon is 200-250ml.

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

1) The total depth of the cardia expansion balloon entering the human body and the position of the lower end of the cardia expansion balloon of the utility model can be fixed, so when the utility model is used for cardia expansion, the cardia balloon can be accurately positioned at the cardia to avoid After traditional cardia expansion balloon positioning, because the position cannot be fixed, the actual expansion position of the balloon is often unclear during expansion, which leads to the problem of insufficient pertinence, which is beneficial to shorten the operation time, reduce surgical complications, and relieve the patient's pain;

2) Since the total depth of the cardia dilation balloon entering the human body and the position of the head end of the cardia dilation balloon of the utility model can be fixed, the endoscope can be taken out after the guide wire is positioned through the endoscope to realize blind expansion. It cannot be realized by the traditional cardia dilation balloon. The utility model can avoid the difficulty of swallowing the endoscope and the cardia dilation balloon at the same time, and reduce postoperative water and bleeding in the throat;

3) The positioning balloon of the utility model is a self-explosive balloon. When the self-explosive balloon passes through the cardia in a bulging state, it will self-explode to prevent tearing of the cardia or esophagus, which can effectively avoid secondary injury to the patient and is safer to use.
