Description

Technical Field

[0001] This invention relates to the field of medical enema equipment technology, specifically to a visual enema probe with a dual-channel self-rinsing structure. Background Technology

[0002] Standardized bowel preparation before colonoscopy relies on enema procedures. Currently, the enema tubes routinely used in clinical practice have a single function, only capable of delivering enema fluid in one direction. The depth of insertion and the judgment of the real-time state of the intestine rely entirely on the personal experience of medical staff, resulting in a significant degree of blindness in the insertion process. This can easily cause mechanical abrasion to the intestinal mucosa. In cases of improper operation or anatomical abnormalities, there is a serious risk of intestinal perforation. This has become a major technical bottleneck restricting the safety and effectiveness of bowel preparation.

[0003] To address the aforementioned issues, while some existing visual enema devices have attempted to incorporate imaging modules, numerous unresolved drawbacks remain. Most of these devices feature only a single working channel, leading to spatial interference between the enema fluid infusion line and the camera line. This makes it difficult to maintain stable and clear real-time imaging while continuously delivering the enema fluid. More significantly, intestinal fluid, feces, and mucus generated during bowel preparation easily adhere to the camera lens surface, causing rapid image blurring. Current solutions require removing the device from the body to wipe the lens, interrupting the procedure, prolonging examination time, and significantly increasing patient discomfort and pain. Furthermore, because the infusion channel and lens cleaning channel are not designed independently, the act of rinsing the lens inevitably disrupts the infusion rhythm of the enema fluid within the intestine, ultimately affecting the bowel cleansing effect and the accuracy of subsequent examinations. Summary of the Invention

[0004] The purpose of this invention is to provide a visual enema probe with a dual-channel self-rinsing structure to solve the problem of inconvenience in using existing traditional Chinese medicine enema devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a visual enema probe with a dual-channel self-rinsing structure, comprising an extension tube fixedly mounted on the enema probe body, a connecting wire fixedly mounted at one end of the extension tube, and the other end of the connecting wire connected to a back-end device; further comprising: an infusion mechanism mounted on the enema probe body, the infusion mechanism comprising a plurality of infusion holes formed on the side wall of the enema probe body, the plurality of infusion holes being circumferentially and equidistantly distributed on the side wall of the enema probe body, an infusion pipe fixedly mounted inside the enema probe body, and the infusion pipe communicating with the plurality of infusion holes; and a camera mechanism mounted on the enema probe body, the camera mechanism including... The enema probe body includes a camera fixedly mounted at its end, with a camera tube fixedly mounted inside the camera, and the camera connected to the connecting line via the camera tube; a plurality of supplementary lights are fixedly mounted on the side of the camera at the end of the enema probe body, and the plurality of supplementary lights are equidistantly distributed in a circumferential pattern on the side of the camera; and a rinsing mechanism is mounted on the enema probe body, the rinsing mechanism including a plurality of rinsing nozzles opened at the end of the enema probe body, the plurality of rinsing nozzles being equidistantly distributed in a circumferential pattern on the side of the camera, a rinsing tube fixedly mounted inside the enema probe body, and the rinsing tube communicating with the plurality of rinsing nozzles.

[0006] Furthermore, the irrigation mechanism also includes an irrigation diversion plate fixedly disposed inside the enema probe body, through which the enema probe body connects the irrigation pipe to a plurality of irrigation holes; and a one-way valve is provided inside the irrigation diversion plate.

[0007] Furthermore, the enema mechanism also includes a receiving pipe fixedly disposed on the extension pipe, and an enema interface is fixedly disposed on the side wall of the receiving pipe, the enema interface being connected to the enema pipeline; the enema fluid is introduced into the enema pipeline through the enema interface.

[0008] Furthermore, the liquid filling mechanism also includes a rounded chamfer integrally formed on several liquid filling holes.

[0009] Furthermore, the camera mechanism also includes a rounded chamfer integrally formed at the end of the enema probe body.

[0010] Furthermore, the flushing mechanism also includes a flushing diversion plate fixedly installed inside the enema probe body, and the flushing pipe is connected to several flushing nozzles through the flushing diversion plate; a one-way valve is also provided inside the flushing diversion plate.

[0011] Furthermore, the flushing mechanism also includes a flushing interface fixedly installed on the receiving pipe; the flushing fluid is introduced into the flushing pipe through the flushing interface.

[0012] Furthermore, the enema probe body is made of medical-grade flexible polymer material.

[0013] Compared with existing technologies, this invention provides a visual enema probe with a dual-channel self-flushing structure. The enema probe body is gently pushed into the intestine through the patient's anus. Once in place, the enema fluid is introduced into the irrigation channel and then evenly distributed to several circumferentially distributed irrigation holes for discharge, achieving intestinal cleaning. Simultaneously, a camera and circumferentially distributed supplementary lights acquire intestinal images in real time, transmitting them to back-end equipment via camera channels and connecting cables for medical personnel to accurately determine the insertion position and intestinal cleanliness. When the camera is obstructed by mucus or feces, there is no need to remove the enema probe body; flushing fluid can be directly introduced into the enema probe body. The flushing fluid is evenly sprayed from several flushing nozzles, directionally rinsing the camera surface. The enema probe body is made of medical-grade flexible polymer material, with a compact structure. The irrigation channel, camera channel, and flushing channel are independent and do not interfere with each other, ensuring that enema infusion and lens cleaning can be performed simultaneously. This significantly improves intestinal preparation efficiency and operational safety, effectively reducing the risk of intestinal perforation caused by blind insertion, and is suitable for routine intestinal preparation before clinical colonoscopy.

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] Example 1:

[0026] This invention provides a visual enema probe with a dual-channel self-rinsing structure, including an extension tube 3 fixedly mounted on the enema probe body 1, a connecting wire 5 fixedly mounted at one end of the extension tube 3, and the other end of the connecting wire 5 connected to a back-end device. It also includes: an infusion mechanism mounted on the enema probe body 1, comprising a plurality of infusion holes 9 formed on the side wall of the enema probe body 1, the plurality of infusion holes 9 being circumferentially and equidistantly distributed on the side wall of the enema probe body 1; an infusion pipe 11 fixedly mounted inside the enema probe body 1, and the infusion pipe 11 communicating with the plurality of infusion holes 9; and a camera mechanism mounted on the enema probe body 1, the camera mechanism comprising a fixedly mounted... A camera 2 is located at the end of the enema probe body 1. A camera tube 12 is fixedly installed inside the camera 2. The camera 2 is connected to the connecting line 5 through the camera tube 12. Several supplementary lights 6 are fixedly installed at the end of the enema probe body 1 on the side of the camera 2. The supplementary lights 6 are distributed in a circumferential shape at equal intervals on the side of the camera 2. A rinsing mechanism is installed on the enema probe body 1. The rinsing mechanism includes several rinsing nozzles 7 opened at the end of the enema probe body 1. The several rinsing nozzles 7 are distributed in a circumferential shape at equal intervals on the side of the camera 2. A rinsing tube 13 is fixedly installed inside the enema probe body 1. The rinsing tube 13 is connected to the several rinsing nozzles 7.

[0027] Simultaneously, by gently pushing the enema probe body 1 into the intestine through the patient's anus, the integrally formed rounded chamfer 8 at its end and the rounded chamfer 10 on the side wall irrigation holes 9 can effectively reduce insertion resistance and avoid mucosal damage. After insertion, the enema fluid is introduced into the irrigation pipe 11 through the irrigation interface 16, and then evenly distributed to several circumferentially distributed irrigation holes 9 through the irrigation distribution plate 14 to achieve intestinal cleansing. The one-way valve built into the distribution plate can prevent backflow and contamination of intestinal waste. At the same time, the camera 2 and the circumferentially distributed... The supplementary light 6 collects intestinal images in real time and transmits them to the back-end equipment through the camera tube 12 and connecting cable 5, allowing medical staff to accurately determine the insertion position and intestinal cleanliness. When the camera 2 is obscured by mucus or feces, there is no need to remove the enema probe body 1; the flushing fluid is directly introduced through the flushing interface 17. The flushing fluid is evenly sprayed out by several flushing nozzles 7 through the flushing tube 13 and flushing diversion plate 15, directionally rinsing the surface of the camera 2. The flushing diversion plate 15 also has a built-in one-way valve to prevent backflow. The enema probe body 1 is made of medical flexible polymer material, with a compact structure. The enema tube 11, camera tube 12, and flushing tube 13 are independent and do not interfere with each other, ensuring that enema infusion and lens cleaning can be carried out simultaneously, significantly improving the efficiency and safety of intestinal preparation, effectively reducing the risk of intestinal perforation caused by blind insertion, and is suitable for routine intestinal preparation before clinical colonoscopy.

[0028] refer to Figures 1-6 The enema mechanism includes an enema probe body 1, an enema hole 9, an enema distribution plate 14, an enema pipe 11, and an enema interface 16;

[0029] By incorporating an enema probe body 1, the enema probe body 1 can be inserted into the patient's intestines before colonoscopy. Enema fluid is then discharged from the enema probe body 1 to clean the patient's intestines. An extension tube 3 is fixedly connected to the enema probe body 1, which extends the connection between the enema probe body 1 and the outside, facilitating operation of the enema probe body 1 by medical personnel outside the patient's body. A receiving tube 4 is fixedly connected to the extension tube 3, and an enema interface 16 is fixedly connected to the receiving tube 4, allowing the enema fluid to be introduced into the extension tube 3 through the enema interface 16 and then into the enema probe body 1. This facilitates the introduction of enema fluid into the patient's intestines for cleaning through the enema probe body 1.

[0030] Meanwhile, several irrigation holes 9 are provided on the side wall of the enema probe body 1, so that the enema fluid introduced by the irrigation interface 16 can be introduced into the patient's intestine through the irrigation holes 9 for cleaning. The irrigation holes 9 are arranged in a circumferential and equidistant pattern, so that the irrigation fluid can be evenly introduced into the patient's intestine when it is introduced. A rounded chamfer 2 10 is integrally formed on the irrigation hole 9, so that the rounded chamfer 2 10 can improve the smoothness of the end of the irrigation hole 9 and avoid the irrigation hole 9 from causing damage to the patient's intestine.

[0031] Secondly, an irrigation diversion plate 14 is fixedly connected inside the enema probe body 1, and an irrigation pipe 11 is fixedly connected to the irrigation diversion plate 14. This allows the enema fluid to be introduced into the extension tube 3 and the enema probe body 1 through the irrigation port 16, and then transported to the irrigation diversion plate 14 by the irrigation pipe 11. The irrigation diversion plate 14 then evenly distributes the enema fluid to several irrigation holes 9 for export, making the enema fluid exported from the several irrigation holes 9 more uniform. In addition, a one-way valve is provided in the irrigation diversion plate 14 to prevent the liquid and other substances in the patient's intestines from flowing back into the irrigation diversion plate 14, thereby avoiding contamination of the enema probe body 1.

[0032] Example 2:

[0033] refer to Figure 1 , Figure 2 and Figure 3 The camera setup includes a camera 2, a fill light 6, a camera tube 12, and a connecting cable 5;

[0034] By fixing a camera 2 to the end of the enema probe body 1, the camera 2 can follow the enema probe body 1 into the patient's intestine and take pictures of the patient's intestine. This facilitates medical staff to observe the patient's intestine, improves the accuracy of medical staff to operate the enema probe body 1, and allows them to observe the condition of the patient's intestine, which is convenient for targeted medical treatment. At the end of the enema probe body 1, on the side of the camera 2, there are several supplementary lights 6 distributed in a circumferential shape at equal intervals. These supplementary lights 6 can be used to illuminate the end of the enema probe body 1, which helps the camera 2 to take pictures and achieves the purpose of facilitating observation by medical staff.

[0035] Meanwhile, an arc chamfer 8 is integrally formed at the end of the enema probe body 1, which increases the smoothness of the end of the enema probe body 1, making it easier for medical staff to operate the enema probe body 1 into the patient's intestines and avoid excessive stimulation and damage to the patient's intestines. A camera tube 12 is fixedly connected inside the enema probe body 1, and a connecting line 5 is fixedly connected at the end of the extension tube 3, so that the camera 2 can be connected to the connecting line 5 through the camera tube 12 and can be connected to the back-end equipment through the connecting line 5. When medical staff use the enema probe body 1, the camera 2 can transmit the captured image to the back-end equipment through the camera tube 12 and the connecting line 5. It also makes it easy for the back-end equipment to power the camera 2 and the supplementary light 6 through the connecting line 5 and the camera tube 12.

[0036] Secondly, the enema probe body 1 is made of medical flexible polymer material, which makes it easy to use the enema probe body 1 safely and stably, and can effectively avoid causing excessive stimulation to the patient. In addition, the end of the enema probe body 1 is fixed with a protective cover made of transparent polymer material, which can protect the camera 2 and several supplementary lights 6.

[0037] Example 3:

[0038] refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The flushing mechanism includes a flushing nozzle 7, a flushing distribution plate 15, a flushing pipe 13, and a flushing interface 17;

[0039] By providing several rinsing nozzles 7 at the end of the enema probe body 1 and on the side of the camera 2, when the enema probe body 1 is used in the patient's intestines, if feces or mucus adhere to the end of the enema probe body 1 and affect the camera 2's recording, the several rinsing nozzles 7 can rinse the end of the enema probe body 1, thereby avoiding obstruction of the camera 2 and facilitating observation by medical staff using the camera 2. Furthermore, the several rinsing nozzles 7 are arranged in a circumferential and equidistant manner on the side of the camera 2, so that the several rinsing nozzles 7 can evenly rinse the outside of the camera 2 to optimize the cleaning effect.

[0040] Meanwhile, a flushing diversion plate 15 is fixedly connected inside the enema probe body 1, and a flushing pipe 13 is fixedly connected to the flushing diversion plate 15. A flushing interface 17 is also fixedly connected to the receiving pipe 4, so that the flushing pipe 13 can connect the flushing diversion plate 15 and the flushing interface 17, so that the flushing fluid can be introduced into the flushing pipe 13 through the flushing interface 17, and then transported to the flushing diversion plate 15 by the flushing pipe 13. Finally, the flushing diversion plate 15 evenly distributes the fluid to several flushing nozzles 7, and the fluid is discharged from the several flushing nozzles 7 for flushing. A one-way valve is also provided in the flushing diversion plate 15 to prevent liquid or other substances in the patient's intestines from entering the enema probe body 1 through the flushing nozzles 7, thereby effectively avoiding contamination of the enema probe body 1.

[0041] Secondly, the filling pipe 11, the camera pipe 12 and the flushing pipe 13 are all set up separately and do not interfere with each other.

[0042] Working Principle: Before operation, connect the connecting cable 5 at the end of the enema probe body 1 to the back-end display and control equipment, and connect the external enema fluid source and the flushing fluid source to the corresponding irrigation interface 16 and flushing interface 17 on the receiving pipe 4 to complete system self-check and pipeline venting. During operation, medical staff hold the extension tube 3 and gently and slowly push the enema probe body 1 into the rectum and sigmoid colon through the patient's anus using the integrally formed arc chamfer 8 at the end of the enema probe body 1 and the arc chamfer 10 on the side wall irrigation hole 9. During the process, the body, made of medical flexible polymer material, can conform to the natural curvature of the intestine, significantly reducing the risk of mechanical stimulation and mucosal damage. During insertion, the camera 2 and several circumferentially distributed supplementary lights 6 start working, acquiring images of the intestinal wall in real time, and transmitting high-definition images to the back-end equipment through the camera pipe 12 and connecting cable 5, allowing medical staff to dynamically observe the insertion depth, intestinal direction and mucosal condition, achieving precise positioning and completely eliminating blind insertion. Once the enema probe body 1 reaches the target depth, the enema function is activated. The enema fluid enters the enema pipeline 11 through the enema interface 16 and is then transported to the enema distribution plate 14. The distribution plate evenly distributes the fluid to several enema holes 9 equidistantly distributed in a circular pattern on the side wall of the enema probe body 1, injecting the enema fluid into the intestines at multiple angles and evenly. The one-way valve built into the enema distribution plate 14 strictly prevents backflow of intestinal waste and fecal matter into the pipeline, ensuring safe infusion. During the enema process, the camera 2 operates continuously, allowing medical staff to assess intestinal cleanliness and fecal expulsion in real time. If the camera 2 is found to be obstructed by intestinal fluid, mucus, or feces, resulting in a blurred view, there is no need to remove the enema probe body 1 from the body. The flushing function can be activated directly. The flushing fluid enters the flushing pipe 13 through the flushing interface 17 and is evenly distributed by the flushing distribution plate 15 to several flushing nozzles 7 equidistantly distributed in a circular pattern on the side of the camera 2 at the end of the enema probe body 1. This sprays the outer surface of the camera 2 from multiple angles and in a directional manner, quickly removing obstructions and restoring a clear view. Similarly, the one-way valve built into the flushing distribution plate 15 effectively prevents backflow contamination. Throughout the process, the enema pipe 11, camera pipe 12, and flushing pipe 13 are set up independently and in parallel inside the enema probe body 1. Enema infusion and lens cleaning can be carried out simultaneously without interference, ensuring a continuous and stable infusion of enema fluid and ensuring that the camera 2 is always in a clear and visible state. After the operation is completed, the enema and flushing functions are turned off, the enema probe body 1 is slowly withdrawn, all interfaces are disconnected, and the instrument is cleaned and disinfected as usual.

[0043] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
