[0002] Intestinal obstruction is one of the common diseases in surgical acute abdomen, which has the characteristics of high incidence, complex etiology and various complications. Therefore, patients must decompress and drain the intestinal obstruction site in time to reduce the pressure at the obstruction site and reduce a series of risks caused by failure to relieve intestinal obstruction symptoms in time.

[0003] At present, most of the 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. During the catheterization process, how to quickly pass the catheter through the pylorus of the stomach becomes the key. Although catheters are often used in conjunction with guidewires in clinical practice, even with the guidance of guidewires, the technical requirements for blind operation are very high. Therefore, a visual intestinal obstruction catheter is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 2 The utility model provides an embodiment: a visual intestinal obstruction catheter, including a guide 1, which is formed by one-time compression molding. The front balloon body 2 is fixedly connected to the outside of the guide 1, and the other end of the front balloon body 2 is fixedly connected to the rear balloon body 4, and the other end of the rear balloon body 4 is fixedly connected to the catheter body 5. The guide 1, the front balloon body 2, the rear balloon body 4 and the catheter body 5 are spliced ​​together to form a complete catheter. The other end of the catheter body 5 is arranged with a divergence part, which is used to connect the catheter with different auxiliary pipelines. The guide 1 is fixedly connected to a visual lens 10-1 inside, and the visual operation of the affected part can be easily realized through the visual lens 10-1. The visual lens 10-1 is the main functional component of the visual component, and an optical lens and an LED lighting lamp are arranged inside, which is a prior art and will not be described in detail here. An optical fiber line 10-2 is fixedly connected to one side of the visual lens 10-1, and the video picture shot by the visual lens 10-1 is transmitted through the optical fiber line 10-2. The other end of the optical fiber line 10-2 is fixedly connected with a plug 10-3, and a decoder 10-4 is arranged outside the leading sub 1, and the other end of the plug 10-3 is plugged into the decoder 10-4. The video shot by the visual lens 10-1 can be decoded by the plug 10-3 and the decoder 10-4, and transmitted to the display device of the hospital in real time. The decoder 10-4 is equipped with a quick-connect socket, which can be directly plugged in and out of the display device of the terminal, which is the prior art and will not be described in detail here. Side holes 3 are provided on the outside of the leading sub 1 and the front balloon body 2.

[0033] Reference Figure 1-Figure 2 The branching part includes a front balloon valve 6, a gas replenishment check valve 7 and a rear balloon valve 8, and one end of the front balloon valve 6, the gas replenishment check valve 7 and the rear balloon valve 8 is connected and connected to the catheter body 5. The end of the catheter body 5 away from the rear balloon body 4 is fixedly connected with a conical discharge port 9. The right tail end of the catheter body 5 and the branching part are integrally welded and formed by molding technology to form a branch shape. The front balloon valve 6, the gas replenishment check valve 7 and the rear balloon valve 8 are respectively installed on the branches of the branch for different operation processing.

[0034] Reference Figure 3-Figure 5 A lens cavity 11 and a guidewire cavity 12 are provided in the middle of the leading guide 1, and both the lens cavity 11 and the guidewire cavity 12 are connected to the leading balloon body 2. The visual lens 10-1 is fixed at the end of the lens cavity 11. The lens cavity 11 is used to fix the visual lens 10-1, and the guidewire cavity 12 is used to provide a passage for the guidewire to pass through. A plurality of flushing water holes 13 are provided inside the leading guide 1, and the flushing water holes 13 are connected to the lens cavity 11. When the visual lens 10-1 is contaminated by enteric substances and the image is unclear, water is injected from the air replenishment one-way valve 7, and the water will pass through the inner cavity channel of the catheter body 5 directly to the flushing cavity of the lens cavity 11 at the head end of the leading guide 1, and will be sprayed out from the flushing water holes 13 in opposite directions to flush the visual lens 10-1.

[0035] Working principle: When the plug 10-3 on one side of the branch part and the decoder 10-4 are connected to the display device of the hospital terminal, the visual lens 10-1 is powered on for observation. At this time, the picture observed by the visual lens 10-1 is transmitted to the decoder 10-4 through the optical fiber line 10-2, and then the information image is processed by the decoder 10-4, so that the picture can be synchronized to the terminal display device of the hospital in real time for medical staff to observe.

[0036] Secondly, after synchronizing the screen on the hospital terminal display device, medical staff can implement catheterization according to the operating method of conventional intestinal obstruction catheters. During the insertion process, since the guide wire lumen 12 is provided at the head end of the guide wire 1, it can still be inserted in conjunction with the guide wire. And with the multiple support of the guide wire, guide wire 1, and visual lens 10-1, the catheter is quickly passed through the pylorus of the stomach and directly reaches the obstruction site. In this process, there is no need for the endoscopy department to use endoscopes for observation, nor is there a need for medical staff and patients to go to the radiology department for confirmation through X-rays.

[0037] After the product enters the stomach or intestine, the visual lens 10-1 may be contaminated by enteric substances due to obstruction, resulting in unclear images. At this time, water is injected for cleaning at the gas replenishment check valve 7 at the bifurcation part. The water will pass through the inner cavity channel of the catheter body 5 directly to the flushing cavity of the lens cavity 11 at the head end of the leading guide 1, and will be sprayed out from the flushing water outlet 13 to flush the visual lens 10-1.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
