Description

Technical Field

[0001] The present application belongs to the technical field of medical equipment, and in particular, relates to an intestinal decompression tube kit used in intestinal obstruction surgery. Background Art

[0002] Intestinal obstruction is a common anorectal general surgery disease, which is mainly manifested by obstacles to the passage of intestinal contents caused by various reasons. The conventional treatment for acquired intestinal obstruction is mainly to clean and decompress the intestine after cutting open the obstructed section of the intestine through surgery. The current conventional cleaning method is to use a gastrointestinal decompression tube along the esophagus to connect a negative pressure device to directly suck out the sediment in the intestine. However, in the current surgical practice, medical staff have found that many patients with mechanical intestinal obstruction seek medical treatment relatively late, and the sediment in the intestine is severely hardened. It is difficult to achieve the purpose of sucking out the obstruction by simply connecting the gastrointestinal decompression tube through the mouth and nose through a negative pressure device.

[0003] The current solution to this problem is to create an opening directly at the location of the obstructed intestine during surgery and connect an intestinal decompression tube to perform negative pressure removal of the obstruction. Although this method can effectively remove the obstruction, it also has some significant drawbacks, such as the complexity of the surgical procedure and the risk of abdominal contamination caused by the intestinal opening. The present invention patent aims to solve these problems and provide a safer and more effective intestinal decompression tube kit for intestinal obstruction surgery. Summary of the invention

[0004] Technical issues to be solved The problem to be solved by the present invention is to provide an intestinal decompression tube kit used in intestinal obstruction surgery to simplify the complicated operation of laparotomy for intestinal decompression surgery and solve the problem that the patient's abdominal cavity is easily contaminated by overflowing intestinal contents.

[0005] Technical Solution In order to achieve the above-mentioned purpose, the present application provides an intestinal decompression tube kit for use in intestinal obstruction surgery, which includes a dilator and a decompression tube. The puncture needle can be mounted on the suction tube of the decompression tube through an interference fit silicone pad. Preferably, the puncture needle of the dilator is consistent in length with the functional tube, and the silicone pad can be interference fit with the inner wall of the suction tube of the decompression tube. After the two are assembled, the puncture needle tip just emerges from the feeding end of the suction tube. Preferably, the rear end of the expander has a non-slip rubber grip to facilitate the operator to exert force during the puncture process. Preferably, the tip of the functional tube is narrowed to facilitate the functional tube to enter the intestinal cavity after the dilator expands the intestinal wall. Preferably, the functional tube has a double-channel structure, one channel of the functional tube is a dilution water tube, and the other channel is a suction tube. Preferably, a balloon is arranged on the outer wall of the functional tube, and behind the balloon is a T-stage structure interference fit on the silicone pad of the functional tube, with the large diameter end of the silicone pad facing the balloon. Relying on the cooperation of the balloon and the silicone pad on the drainage tube, it is not necessary to suture and fix the intestine during intestinal decompression. It can not only be firmly fixed, but also seal the penetration point to isolate the intestinal cavity from the external environment, avoid secondary injury, reduce the risk of infection, and have a simple overall structure and convenient operation. Preferably, the functional tube has an air flow channel connecting the inflation interface to the balloon. Preferably, the tail end of the dilution tube has a water injection interface, and a plug is provided on the water injection interface.

[0006] Beneficial effects: In view of the problems existing in existing intestinal obstruction surgical procedures, the present invention designs a new decompression kit, which uses a dilator to puncture the intestinal tract and allow the decompression tube to enter the intestinal cavity. The silicone pad with a T-stage structure has a smaller resistance when pushed toward the balloon, but a larger resistance when pushed in the opposite direction. The fixing effect of the silicone pad and the balloon can effectively prevent the decompression tube from loosening and the intestinal contents from overflowing, greatly reducing the risk of abdominal cavity contamination during intestinal decompression.

DETAILED DESCRIPTION

[0009] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0010] Example: See also Figures 1 to 3 This embodiment provides an intestinal decompression kit used in intestinal obstruction surgery, which includes a decompression tube 1 and a dilator 2. The decompression tube 1 includes: a functional tube 11, a suction tube 14 connected to the drainage system of the operating room, a water injection interface 16 with a plug 18, a T-stage structure silicone pad 13 and a balloon 12 that are interference-fitted with the functional tube; the dilator 2 includes: a puncture needle 21, a matching silicone pad 22 and a handheld part 23.

[0011] The functional tube 11 is a double-channel straight tube structure. One channel of the functional tube 11 is set as a dilution tube 15, and the other channel is set as a suction tube 14. An air flow channel connecting the balloon 12 and the inflation interface 17 is set inside.

[0012] The silicone pad 13 is a T-stage structure with the large diameter end facing the balloon 12. This structure is conducive to the operator pushing the silicone pad 13 toward the balloon, while the resistance is greater when pushing in the opposite direction, which is convenient for fixing the decompression tube 1 while reducing the overflow of intestinal contents causing abdominal cavity contamination.

[0013] In clinical application: First, the dilator 2 is assembled with the decompression tube 1 by matching the silicone pad 22. The operator holds the hand-held portion 23 of the dilator 2 and penetrates the intestinal wall with the puncture needle 21. After the penetration is completed, the dilator 2 is removed, and the balloon 12 at the front end of the decompression tube 1 is ensured to remain in the intestinal cavity. The passage between the outside and the intestinal cavity is established through the decompression tube 1.

[0014] Fluid is injected into the balloon 12 through the inflation interface 17 by means of an instrument, wherein the instrument may be a syringe, so as to expand the balloon 12. After the balloon 12 is expanded, the silicone pad 13 is pushed toward the balloon 12 to prevent the decompression tube 1 from loosening and the intestinal contents from overflowing and causing abdominal infection.

[0015] Finally, the drainage system interface and the suction tube 14 are connected to each other to effectively perform intestinal decompression.

[0016] The dilution tube 15 in the functional tube 11 is provided with a water injection interface 16 at the tail end, and a plug 18 is provided on the water injection interface 16. When the decompression tube 1 is blocked or the decompression intestine is broken and drug treatment, disinfection and cleaning are required, the plug 18 can be opened and the injection cleaning and other operations can be performed by connecting the syringe and the water injection interface 16.

[0017] Although the present application is described above with reference to specific embodiments, it should be understood by those skilled in the art that many modifications may be made to the configurations and details disclosed in the present application within the principles and scope disclosed in the present application. The scope of protection of the present application is determined by the appended claims, and the claims are intended to cover all modifications included in the technical features or scope of the claims.
