Technical Field

The invention relates to the field of medical instruments, in particular to an intestinal canal built-in drainage device with a balloon.

Background

At present, for low rectal cancer patients, a conventional operation mode adopted by the patients is laparoscopic low rectal cancer radical operation, but for patients with high risk factors of postoperative anastomotic fistula (such as obesity/diabetes/vascular variation or combined atherosclerosis) or unreliable anastomosis (reasons of high anastomosis tension or poor blood circulation and the like), in order to prevent the occurrence of the postoperative anastomotic fistula, a mode of ileal end preventive stoma is usually adopted to reduce the occurrence probability of the anastomotic fistula and promote early recovery of the postoperative patients; research proves that the preventive terminal ileum ostomy can reduce the occurrence of postoperative anastomotic fistula to a certain extent, realize the advantages of early feeding of patients, shortening the hospitalization time of the patients and the like; the principle analysis of the method is that the colon and the rectum can be arranged in an open manner through the preventive terminal ileum stoma, so that digestive juice and excrement do not pass through the rectum anastomosis, the full diversion of the excrement and the intestinal juice is realized, the pollution and the influence of the anastomosis of the excrement and the intestinal juice are eliminated, and the healing of the anastomosis is promoted. After preventive stoma, however, the operation is usually performed again 3-6 months after the operation, and the stoma is returned; this often increases the psychological and economic burden on the patient, and re-surgery is prone to new postoperative complications.

Disclosure of Invention

In order to solve the problems, the invention provides an intestinal canal built-in type drainage device with a balloon, which can realize the same function as the preventive ileum tail end stoma and avoid carrying out secondary operation on a patient.

In order to achieve the purpose, the invention adopts the technical scheme that:

the intestinal canal built-in type drainage device with the balloon comprises a drainage tube, an inflatable balloon sleeved on the front section of the drainage tube, a spongy cushion arranged on the outer side of the inflatable balloon and an in-vitro inflation device communicated with the inflatable balloon.

Furthermore, the external inflation device adopts an external balloon inflation device which is communicated with the inflatable balloon through a rubber inflation tube and is not communicated with the lumen of the drainage tube, and the rubber inflation tube is provided with a valve.

Furthermore, the spongy cushion is formed by connecting a plurality of spongy cushions, is cylindrical and is sleeved outside the inflatable balloon.

Further, the spongy cushion is sewn with the rear wall of the pipe orifice of the drainage pipe.

Further, the diameter of the inflatable balloon is shorter than the length of the spongy cushion, and the length of the spongy cushion is set to be 2 times of the length of the inflatable balloon, so that a larger attaching area between the spongy cushion and the intestinal wall after the balloon is inflated is ensured.

Further, the thickness of the sponge cushion is generally required to be about 1-1.5cm, so that the pressure of the saccule on the wall of the intestinal canal can be buffered and reduced to the maximum extent after the saccule is inflated.

The invention has the following beneficial effects:

can realize the same function as the preventive ileum tail end stoma, and can avoid carrying out secondary operation on patients.

Detailed Description

The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that variations and modifications can be made by persons skilled in the art without departing from the spirit of the invention. All falling within the scope of the present invention.

As shown in fig. 1, an intestinal canal built-in drainage device with a balloon comprises a drainage tube 1, an inflatable balloon 2 sleeved on the front section of the drainage tube 1, a sponge cushion 3 arranged on the outer side of the inflatable balloon 2, and an in vitro inflation device 4 communicated with the inflatable balloon 2. The external inflation device 4 adopts an external balloon inflation device which is communicated with the inflatable balloon 2 through a rubber inflation tube 5 and is not communicated with the lumen of the drainage tube 1, and the rubber inflation tube 5 is provided with a valve (similar to a balloon inflation tube of a catheter, can be inflated and deflated after being connected with an injector, and the valve can control the balloon to be airtight after being removed); the spongy cushion 3 is formed by connecting a plurality of spongy cushions, is cylindrical and is sleeved outside the inflatable balloon 2. The drainage tube 1 and the external inflation device 4 are made of rubber materials, the wall of the inflatable saccule 2 is required to be soft, the inflatable saccule can be made of materials similar to a balloon, such as latex materials, and the external drainage bag 6 is in butt joint with the tail end of the drainage tube 1. The diameter of the inflatable sacculus 2 is shorter than the length of the spongy cushion 3, and the length of the spongy cushion 3 is set to be 2 times of the length of the inflatable sacculus 2, so that the larger attaching area between the spongy cushion and the intestinal wall after the sacculus is inflated is ensured. The thickness of the spongy cushion is generally required to be about 1-1.5cm, so that the pressure of the saccule on the wall of the intestinal canal can be buffered and reduced to the maximum extent after the saccule is inflated.

Preferably, as shown in FIG. 2, the sponge pad 3 may be sutured with the rear wall of the nozzle of the drainage tube 1.

The application method of the specific implementation comprises the following steps: after the laparoscopic rectal cancer radical operation is finished, the drainage device is inserted from the anus, the part with the sacculus is placed at about 20cm above an anastomotic stoma, after the position is placed, the sacculus is inflated by an external inflation device, the short diameter of the inflated sacculus is less than or equal to the diameter of the intestinal canal cavity, the operation can be controlled under the direct vision of the laparoscope, and the intestinal canal cannot be obviously expanded after the sacculus is inflated; the spongy cushion outside the saccule can fully close the gap between the drainage device and the intestinal canal, effectively reduce the pressure of the saccule filling on the intestinal canal and avoid the blood circulation disorder of the intestinal canal wall; the balloon can be opened to fully intercept excrement and intestinal fluid in the intestinal canal at the near end of the device, and the intestinal fluid and the excrement can be fully led out of the body through the inner opening of the drainage device; in addition, the drainage device can realize the flushing of the intestinal canal through the outer opening of the drainage device, and is favorable for the sufficient drainage of the excrement.

The foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by one skilled in the art within the scope of the appended claims without departing from the spirit of the invention. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.
