Description

Technical Field

[0001] This invention relates to the field of colonoscopy technology, and more specifically, to a colonoscopy-aiding device. Background Technology

[0002] A colonoscope is a flexible, fiber optic tube with a miniature camera at the tip, used to examine the inside of the large intestine (colon and rectum). Before the examination, the patient must empty their bowels. During the examination, the patient usually lies on their side, and the doctor slowly inserts the colonoscope through the anus, inflating the intestinal lumen with air and advancing it towards the ileocecal junction while observing the patient. During the procedure, the camera transmits real-time images to a monitor, allowing the doctor to clearly examine the mucosa for inflammation, polyps, tumors, or other lesions. Small polyps can be removed directly; suspicious areas can be biopsied for pathological examination. The entire procedure takes approximately 15-30 minutes and is usually performed under sedation and anesthesia to improve comfort. Currently, gastrointestinal obstruction is one of the advantageous diseases treated by integrated traditional Chinese and Western medicine in general surgery. Our department has achieved significant efficacy in treating low-level colorectal malignant obstruction using colonoscopic stent placement combined with laparoscopic radical resection and primary anastomosis. However, in clinical practice, problems exist such as significant fecal spillage during colonoscopy, difficulties in nursing care, and contamination of the operating room floor and air. Furthermore, fluid retention in the intestinal lumen during the examination can obstruct the colonoscope camera, hindering medical staff from observing the actual symptoms within the intestinal lumen. Currently, there is no suitable method to solve these problems during colonoscopy. Summary of the Invention

[0003] This invention provides a colonoscopy auxiliary device that solves the problems in related technologies during clinical medical procedures, such as excessive fecal spillage during colonoscopy, difficulties in nursing care, and pollution of the operating room floor and air. Additionally, the accumulation of fluid in the intestinal lumen during examination obstructs the colonoscopy camera, hindering medical staff from observing the actual pathological information within the intestinal lumen.

[0004] This invention provides a colonoscopy-assisted device, comprising a main body, an external balloon fixedly mounted on the main body, a baffle disposed on the outside of the main body, a guide rod slidably mounted inside the main body, a colonoscopy channel housing fixedly mounted at the end of the main body, a catheter connected to the outside of the main body near the baffle, a clamp device disposed on the outside of the catheter, an anti-clogging device disposed inside the catheter, the clamp device being used to cut off the flow in the catheter, the anti-clogging device being used to break up impurities inside the main body, a cleaning collection component disposed at the bottom end of the catheter, the cleaning collection component being used to collect liquid and impurities flowing out of the catheter, a thin flexible tube connected to the outside of the external balloon, an inflation / deflation valve fixedly mounted at the end of the thin flexible tube, and inflation of the inflation / deflation valve being used to adjust the shape of the external balloon.

[0005] As a further optimization of the present invention, the pipe clamp device includes a fixing ring fixedly installed on the outside of the conduit, with compression ports symmetrically installed on the inner wall of the fixing ring, a rotating column rotatably installed on the top of the fixing ring, a fixing plate fixedly installed on the outside of the conduit located on the top of the fixing ring, the rotating column being threadedly installed with the fixing plate, and a rotating nut fixedly installed on the top of the rotating column.

[0006] As a further optimization of the present invention, the cleaning collection component includes a quick-change male connector fixedly installed at the bottom of the conduit, a quick-change female connector sleeved on the outside of the quick-change male connector, a lifting lug and a quick-release cap fixedly installed on the outside of the quick-change female connector, the lifting lug and quick-release cap being symmetrically arranged about the quick-change female connector, and a cleaning bag fixedly installed at the bottom of the quick-change female connector.

[0007] As a further optimization of the present invention, the anti-blocking device includes a fixing block fixedly installed on the inner wall of the conduit, an adjusting member is provided on the top of the fixing block, a breaking member is connected to the top of the adjusting member, and a locking ball is fixedly installed on the bottom of the adjusting member.

[0008] As a further optimization of the present invention, the adjusting component includes an adjusting motor fixedly installed on the top of the fixed block, a first adjusting column slidably installed inside the adjusting motor, an adjusting ring fixedly installed on the top of the adjusting motor, the top of the adjusting motor being rotatably connected to the crushing component, an adjusting spring being provided outside the first adjusting column, and a locking ball being fixedly connected to the bottom of the first adjusting column.

[0009] As a further optimization of the present invention, the crushing component includes a lower plate rotatably mounted on the top of an adjusting ring, an upper plate meshing with the top of the lower plate, a first connecting protrusion arranged in a circular array on the outer side of the upper plate, a second connecting protrusion rotatably mounted inside the first connecting protrusion, a first crushing block fixedly mounted at the end of the second connecting protrusion, a crushing connecting column rotatably mounted inside the first crushing block, a third connecting protrusion arranged in a circular array on the outer side of the lower plate, a fourth connecting protrusion rotatably mounted inside the third connecting protrusion, a second crushing block fixedly mounted at the end of the fourth connecting protrusion, and the second crushing block rotatably connected to the crushing connecting column.

[0010] As a further optimization of the present invention, the inflation / deflation valve is provided with a small air bladder that is connected to it.

[0013] As a further optimization of the present invention, when the broken part is fully retracted, the locking ball is located at the lower part of the extrusion port.

[0014] The beneficial effects of this invention are as follows: The colonoscopy auxiliary device described in this invention adjusts the expansion of the external balloon through an inflation / deflation valve, allowing the external balloon to make close contact with the patient's rectum. An anti-blocking device breaks up liquids and impurities entering the catheter, preventing large pieces from clogging the catheter's interior. When the cleaning collection unit collects liquids and impurities from the patient's rectum, if the unit is full, it can be locked by a clamping device for easy replacement. This improves the safety and hygiene of the doctor during colonoscopy and enhances the patient's experience. Attached Figure Description

Detailed Implementation

[0017] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0018] like Figures 1 to 6 As shown in the embodiment of the present invention, a colonoscopy auxiliary device includes a main body 1, an external balloon 11 fixedly mounted on the main body 1, a baffle 4 disposed on the outside of the main body 1, a guide rod 2 slidably mounted inside the main body 1, a colonoscopy channel shell 3 fixedly mounted at the end of the main body 1, a catheter 5 connected to the outside of the main body 1 near the baffle 4, a tube clamp device 8 disposed on the outside of the catheter 5, an anti-blocking device 10 disposed inside the catheter 5, the tube clamp device 8 being used to cut off the flow in the catheter 5, the anti-blocking device 10 being used to break up impurities inside the main body 1, a cleaning collection member 9 disposed at the bottom end of the catheter 5, the cleaning collection member 9 being used to collect liquid and impurities flowing out of the catheter 5, a thin flexible tube 6 connected to the outside of the external balloon 11, an inflation / deflation valve 7 fixedly mounted at the end of the thin flexible tube 6, and inflation / deflation valve 7 being used to adjust the shape of the external balloon 11.

[0019] It should be noted that when a colonoscope is needed, the gas inside the external balloon 11 is released through the inflation / deflation valve 7. The main body 1 is then inserted into the patient's body. The inflation / deflation valve 7 then inflates the external balloon 11, ensuring close contact between the external balloon 11 and the patient's rectal wall, preventing waste from flowing out through the external balloon 11. The baffle 4 can limit the position. The guide rod 2 then assists in inserting the main body 1 into the patient's body. After the main body 1 is inserted, the guide rod 2 is removed, and the colonoscope is then inserted from the main body 1 into the patient's body to examine the rectum. If there is waste in the patient's rectum, it can flow into the catheter 5 through the gap between the main body 1 and the colonoscope. If the fluid flowing into the catheter 5 contains impurities, it can cause blockage, resulting in discomfort for the patient during the examination. Therefore, an anti-blockage device 10 is provided. The device can break up impurities inside the catheter 5, allowing the impurities and liquid flowing through the catheter 5 to enter the cleaning collection unit 9. Once the cleaning collection unit 9 is full, the catheter 5 can be clamped and locked using the clamp device 8, after which the cleaning collection unit 9 can be replaced. This prevents the liquid inside the catheter 5 from flowing out during the examination. The device adjusts the expansion of the external balloon 11 through the inflation / deflation valve 7, ensuring that the external balloon 11 can make close contact with the patient's rectum. The anti-blocking device 10 breaks up the liquid and impurities entering the catheter 5, preventing large pieces of impurities from clogging the inside of the catheter 5. When the cleaning collection unit 9 collects the liquid and impurities from the patient's rectum, if the inside of the cleaning collection unit 9 is full, it can be locked by the clamp device 8, making it easy to replace the cleaning collection unit 9. This improves the safety and hygiene of doctors during colonoscopy and enhances the patient's experience during the examination.

[0020] like Figures 2 to 5 As shown, the pipe clamp device 8 includes a fixing ring 81 fixedly installed on the outside of the conduit 5. The inner wall of the fixing ring 81 is symmetrically equipped with extrusion ports 82. A rotating column 83 is rotatably installed on the top of the fixing ring 81. A fixing plate 85 is fixedly installed on the outside of the conduit 5 located on the top of the fixing ring 81. The rotating column 83 is threadedly installed with the fixing plate 85. A rotating nut 84 is fixedly installed on the top of the rotating column 83.

[0021] It should be noted that when the conduit 5 needs to be locked, the rotating nut 84 can be rotated. Rotating the nut 84 will drive the rotating column 83 to rotate, which will cause the top of the fixing ring 81 to descend. This will bring the two extrusion ports 82 closer together, thus locking the conduit 5. The top and bottom of the fixing ring 81 can be made of fixed plastic material, while the connecting part in the middle of the fixing ring 81 can be made of rubber material. Therefore, when the rotating column 83 rotates, it will cause the fixing ring 81 to contract, thereby bringing the extrusion ports 82 closer together and achieving the locking effect of the conduit 5.

[0022] like Figures 1 to 3 As shown, the cleaning collection component 9 includes a quick-change male connector 95 fixedly installed at the bottom of the conduit 5. A quick-change female connector 93 is sleeved on the outside of the quick-change male connector 95. A lifting lug 94 and a quick-release cap 92 are fixedly installed on the outside of the quick-change female connector 93. The lifting lug 94 and the quick-release cap 92 are symmetrically arranged about the quick-change female connector 93. A cleaning bag 91 is fixedly installed at the bottom of the quick-change female connector 93.

[0023] It should be noted that the quick-change male connector 95 and quick-change female connector 93 can be connected by a snap-fit ​​to prevent them from falling off. The quick-change female connector 93 is equipped with a quick-release cap 92 and a lifting lug 94 on the outside, which facilitates the sealing and disassembly of the cleaning bag 91.

[0024] like Figures 4 to 7 As shown, the anti-blocking device 10 includes a fixing block 102 fixedly installed on the inner wall of the conduit 5. An adjusting member 103 is provided on the top of the fixing block 102. A breaking member 101 is connected to the top of the adjusting member 103. A locking ball 104 is fixedly installed on the bottom of the adjusting member 103.

[0025] It should be noted that when impurities are present inside the conduit 5 and need to be broken up, the adjusting component 103 can be activated. The adjusting component 103 drives the crushing component 101 to rotate. The position of the locking ball 104 is adjusted by the pipe clamp device 8, thereby causing the crushing component 101 to extend or retract. When the squeezing port 82 is not locked to the locking ball 104, the crushing component 101 can open. At the same time, the adjusting component 103 drives the crushing component 101 to rotate, and the impurities inside the conduit 5 are broken up by the crushing component 101, preventing blockage. When the conduit 5 is locked by the pipe clamp device 8 and the locking ball 104 is lowered, the crushing component 101 retracts. When the crushing component 101 is fully retracted, it is the same size as the diameter of the inner wall of the conduit 5, thus sealing the inside of the conduit 5 and preventing leakage when replacing the cleaning collection component 9.

[0026] like Figures 6 to 7 As shown, the adjusting component 103 includes an adjusting motor 1034 fixedly installed on the top of the fixed block 102. A first adjusting column 1032 is slidably installed inside the adjusting motor 1034. An adjusting ring 1031 is fixedly installed on the top of the adjusting motor 1034. The top of the adjusting motor 1034 is rotatably connected to the crushing component 101. An adjusting spring 1033 is provided on the outside of the first adjusting column 1032. A locking ball 104 is fixedly connected to the bottom of the first adjusting column 1032.

[0027] It should be noted that when the first adjusting column 1032 rises, the crushing component 101 can be unfolded. The adjusting spring 1033 ensures that the crushing component 101 is in the unfolded state under normal conditions. When the pipe clamp device 8 locks the locking ball 104, the crushing component 101 is in the retracted state. The adjusting motor 1034 starts and can drive the first adjusting column 1032 to rotate, thereby driving the crushing component 101 to rotate, so as to achieve the function of crushing impurities in the liquid inside the conduit 5.

[0028] like Figures 6 to 7 As shown, the crushing component 101 includes a lower plate 1019 rotatably mounted on top of an adjusting ring 1031. An upper plate 1011 engages with the top of the lower plate 1019. A first connecting protrusion 1012 is arranged in a first circumferential array on the outer side of the upper plate 1011. A second connecting protrusion 1013 is rotatably mounted inside the first connecting protrusion 1012. A first crushing block 1014 is fixedly mounted at the end of the second connecting protrusion 1013. A crushing connecting column 1018 is rotatably mounted inside the first crushing block 1014. A third connecting protrusion 1015 is arranged in a third circumferential array on the outer side of the lower plate 1019. A fourth connecting protrusion 1016 is rotatably mounted inside the third connecting protrusion 1015. A second crushing block 1017 is fixedly mounted at the end of the fourth connecting protrusion 1016. The second crushing block 1017 is rotatably connected to the crushing connecting column 1018.

[0029] It should be noted that when the extrusion port 82 is not locked to the locking ball 104, the lower plate 1019 can be raised by adjusting the spring 1033, so that the first crushing block 1014 and the second crushing block 1017 are fully extended. The motor 1034 is started, which can drive the first crushing block 1014 and the second crushing block 1017 to rotate, thereby achieving the effect of crushing the liquid and impurities passing through the crushing part 101 and preventing the conduit 5 from becoming blocked. The upper plate 1011 and the lower plate 1019 can be fully engaged into a cylindrical state. Therefore, when the upper plate 1011 and the lower plate 1019 are fully engaged into a cylinder, the first crushing block 1014 and the second crushing block 1017 can contact each other, thereby forming an isolation plate to isolate and seal the upper and lower parts of the crushing part 101. At this time, the extrusion port 82 is locked to the locking ball 104, which facilitates the replacement of the cleaning collection part 9.

[0030] like Figures 1 to 4 As shown, the inflation / deflation valve 7 is equipped with a small air bladder that is connected to it. The small air bladder is in pressure communication with the external air bladder 11 and is used to indirectly indicate the internal pressure of the external air bladder 11 through touch.

[0031] It should be noted that the small airbag is completely connected to the thin tubing 6 and the entire inflation system of the external airbag 11 through the channel inside the inflation / deflation valve 7, ensuring that its internal pressure is equal to that of the external airbag 11 inside the patient's rectum in real time. During the inflation of the external airbag 11 using a syringe, the operator does not need to rely entirely on experience or guesswork. By gently squeezing the small airbag outside the body with their fingers and sensing the firmness and elasticity of the small airbag, the operator can intuitively and safely judge the expansion pressure of the rectal airbag, effectively preventing the risk of patient discomfort or tissue damage due to overinflation, and improving the safety and controllability of the operation.

[0032] like Figures 1 to 3 As shown, the tail end of the main body 1 is set vertically downward at 90° relative to the longitudinal axis of the main body 1 and is connected to the conduit 5.

[0033] It should be noted that the tail end of the main body 1, near the connection point of the catheter 5, does not extend in a straight line, but is designed to bend vertically downwards at a 90° angle to the longitudinal axis of the main body 1. This structural design fully considers the left lateral decubitus position that patients usually adopt during colonoscopy. In this position, the anal region is at its lowest point. The vertically downward-facing sewage outlet ensures that, under the influence of gravity, the liquid and semi-fluid excrement in the intestinal lumen can be guided out most smoothly and thoroughly, with almost no residue, greatly improving sewage discharge efficiency and optimizing the cleaning effect from a physical structural perspective.

[0034] like Figure 1 As shown, the cleaning bag 91 is provided with liquid capacity markings.

[0035] It should be noted that the clean bag 91 is equipped with a liquid volume mark, which can monitor the volume of fluid discharged by the patient, thereby allowing for observation and testing of the fluid in the patient's body and improving the monitoring of the patient's physical condition during examination.

[0036] like Figures 4 to 7 As shown, when the broken piece 101 is fully retracted, the locking ball 104 is located below the extrusion port 82.

[0037] It should be noted that when the broken piece 101 is fully retracted, the locking ball 104 is located below the extrusion port 82. When the pipe clamp device 8 locks the conduit 5, the extrusion port 82 can lock the locking ball 104.

[0038] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of the embodiments described above, all of which are within the protection scope of the present invention.
