Description

Technical Field

[0001] This utility model relates to the technical field of intestinal obstruction catheter devices, specifically to a novel intestinal obstruction catheter with a pre-covered side hole of enterocoating membrane. Background Technology

[0002] Intestinal obstruction is a common surgical emergency, characterized by high incidence, complex etiology, and diverse complications. Therefore, it is crucial to promptly decompress and drain the obstructed area to reduce pressure and minimize the risks associated with delayed relief of symptoms.

[0003] Currently, most intestinal obstruction treatment catheters used in clinical practice are inserted into the patient's stomach through the nose, and then enter the duodenum and lower digestive tract through the pylorus of the stomach. However, when using the catheter, the guidewire can easily pass through the side hole and exit the tube body, affecting the surgical operation and increasing the operation time. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a novel intestinal obstruction catheter with a pre-covered side hole of enteric membrane, which effectively solves the problem in existing technologies where the guidewire easily passes through the side hole and exits the catheter body, affecting surgical procedures and increasing surgical time.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a novel intestinal obstruction catheter with a pre-covered side hole of enteric coating. The catheter includes a catheter body and a ventilator tube. One end of the catheter body and the ventilator tube are connected. The bottom end of the catheter body is provided with a steel ball hole. The top end of the steel ball hole is provided with a side hole. The top end of the side hole is provided with an anterior balloon and a posterior balloon. An anterior tube hole is provided between the anterior balloon and the posterior balloon. The top end of the posterior balloon is provided with a posterior tube hole. The top end of the ventilator tube is connected to a negative pressure drainage port and multiple sets of vacuum tubes. The top ends of the vacuum tubes on both sides are respectively fixed with an anterior balloon inflation port and a posterior balloon inflation port.

[0009] Furthermore, the front and rear boreholes are arranged in multiple equidistant arrays.

[0010] Furthermore, a steel ball is disposed inside the ball hole.

[0011] Furthermore, the middle part of both the anterior and posterior balloons is filled with an inflatable balloon structure, the anterior balloon has a diameter of 2-3 cm after inflation, and the posterior balloon has a diameter of 3-5 cm after inflation.

[0012] Furthermore, the steel ball hole, the front tube hole, and the rear tube hole are distributed at distances of 5cm, 20cm, and 70-80cm from the end of the catheter body.

[0013] Beneficial effects

[0014] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0015] This invention features a 3.5-4 meter long catheter structure, suitable for current intestinal obstruction surgeries and meeting clinical needs. The catheter's distal end has a steel ball hole structure with two embedded steel balls, facilitating turning and traversing narrow intestinal obstructions. The anterior balloon, inflated to a diameter of 2-3 cm, guides the catheter downwards; the posterior balloon, inflated to a diameter of 3-5 cm, facilitates intestinal fixation, prevents reflux, and allows for intestinal rearrangement during surgery. Multiple side holes, including anterior and posterior holes, are located at 5 cm, 20 cm, and 70-80 cm from the distal end of the catheter. These side holes are pre-covered with enteric-coated membrane (which dissolves naturally after 2-3 hours; intestinal obstruction catheter surgery time is 30 minutes to 2 hours), exposing the side holes and facilitating drainage from multiple points in the intestine. The pre-covering of the side holes with enteric-coated membrane prevents the guidewire from passing through the side holes during the procedure, thus reducing surgical time.

[0022] Example: A novel intestinal obstruction catheter with pre-covered side holes and enteric coating, see attached figure. Figure 1 -Appendix Figure 2 The device includes a catheter 1, which comprises a catheter body 8 and a ventilator 13. One end of the catheter body 8 and the ventilator 13 are connected. The bottom end of the catheter body 8 is provided with a steel ball hole 2. The top end of the steel ball hole 2 is provided with a side hole 3. The top end of the side hole 3 is provided with an anterior balloon 4 and a posterior balloon 6. An anterior tube hole 5 is provided between the anterior balloon 4 and the posterior balloon 6. The top end of the posterior balloon 6 is provided with a posterior tube hole 7. The top end of the ventilator 13 is connected to a negative pressure drainage port 12 and multiple sets of vacuum tubes 10. The top ends of the vacuum tubes 10 on both sides are respectively fixed with an anterior balloon inflation port 9 and a posterior balloon inflation port 11. The 3.5-4 meter long catheter structure 8 is suitable for current intestinal obstruction surgery and meets clinical needs.

[0023] The anterior tube hole 5 and the posterior tube hole 7 are arranged in multiple sets at equal intervals; the steel ball hole 2 structure opened at the end of the catheter body 8 has two steel balls embedded in it, which makes it easier to turn and cross the narrowing of intestinal obstruction.

[0024] A steel ball is placed inside the steel ball hole 2; the middle of the anterior balloon 4 and the posterior balloon 6 are both filled with an inflatable balloon structure. The diameter of the anterior balloon 4 after inflation is 2-3 cm, and the diameter of the posterior balloon 6 after inflation is 3-5 cm. The diameter of the anterior balloon 4 after inflation is 2-3 cm, which facilitates the downward guidance of the catheter 1; the diameter of the posterior balloon 6 after inflation is 3-5 cm, which facilitates the fixation of the intestinal tract, prevents reflux, fixes the intestinal tract, and allows for intestinal rearrangement during the operation.

[0025] The steel ball hole 2, the front tube hole 5, and the rear tube hole 7 are located at distances of 5cm, 20cm, and 70-80cm from the end of the catheter body 8. Multiple side holes, such as side hole 3, front tube hole 5, and rear tube hole 7, are also located at distances of 5cm, 20cm, and 70-80cm from the end of the catheter body 8. These side holes are pre-covered with enteric-coated membrane (which dissolves naturally after 2-3 hours; the procedure time for intestinal obstruction catheterization is 30 minutes to 2 hours), exposing the side holes and facilitating drainage from multiple points in the intestine. The pre-covering of the side holes with enteric-coated membrane prevents the guidewire from passing through the side holes and exiting the catheter body during the procedure, thus reducing the time required for the procedure.
