Description

Technical Field

[0001] This invention relates to the field of anorectal examination technology, and in particular to a multi-light source anorectal examination endoscope for anorectal use. Background Technology

[0002] An anoscope is a traditional medical instrument commonly used in proctology for observation and treatment. It allows direct visualization of the rectum for polyps or hemorrhoids, clearly showing their location, size, and shape, making it a fundamental method for diagnosing hemorrhoids. However, current anoscopes are limited by their structure and lighting conditions, resulting in unclear exposure of the patient's surgical site and making observation difficult for doctors. The main technical problems include:

[0003] 1. The light source of the anoscope is in a single position, making it difficult to adjust the local light for different reflective environments and failing to meet the lighting needs of different areas;

[0004] 2. Due to the structural and operational limitations of the anoscope, it may be difficult to simultaneously insert the lens and medication nozzle into the anoscope, which may affect the convenience and accuracy of the operation. The inability to insert them simultaneously makes the operation cumbersome, potentially requiring multiple adjustments to the device position, increasing operation time and patient discomfort, and may also affect the observation of the ulcer site and the accuracy of medication application.

[0005] 3. Due to the relatively small space inside the rectum, with its bends and folds, the field of vision and operating space of the anoscope are limited. The medication nozzle may not be able to accurately spray the medication to the specific site of the rectal ulcer, thus affecting the treatment effect. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned problems existing in the prior art, and to propose a multi-light source anoscope device for proctology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multi-source anorectal examination endoscope device for proctology, comprising an endoscope body, an endoscope core, a first mounting cylinder, a second mounting cylinder, and a handheld camera. The endoscope core, the first mounting cylinder, and the second mounting cylinder are inserted into the endoscope body sequentially as needed during surgery. A first connecting shell is fixedly connected to the rear end of the first mounting cylinder, and a second connecting shell is fixedly connected to the rear end of the second mounting cylinder. The front end of the endoscope body is rolled inward to form a mounting ring, and an annular groove is formed between the mounting ring and the inner wall of the endoscope body. A protective cover is fixedly installed at the rear end of the endoscope body, and a first mounting shell that mates with the first mounting cylinder or a second mounting shell that mates with the second mounting cylinder is detachably installed at the rear end of the protective cover.

[0008] A lighting mechanism is sleeved on the outside of the first mounting cylinder. The lighting mechanism includes a first lamp ring, a second lamp ring, and a third lamp ring that are sleeved on the outside of the first mounting cylinder from front to back, as well as an adjustment component disposed between the three.

[0009] The second mounting cylinder is equipped with a spraying mechanism, which includes a first nozzle and a plurality of second nozzles located on the front side of the second mounting cylinder, and a transport assembly located at the rear of the second mounting cylinder.

[0010] Preferably, a handle is fixedly installed on the side wall of the protective cover, and the grip of the handheld camera is connected to the handle through two connecting plates.

[0011] Preferably, the diameter of the second mounting cylinder is slightly smaller than that of the first mounting cylinder to avoid friction between the second mounting cylinder and the first, second, and third lamp rings, which could cause them to shift, when the second mounting cylinder is inserted.

[0012] Preferably, the adjustment assembly includes multiple connecting rods disposed between the first lamp ring and the second lamp ring, and between the second lamp ring and the third lamp ring, and multiple rotating rods disposed on the rear side of the third lamp ring. Each connecting rod has an electric suction cup fixedly connected to both ends and the front end of each rotating rod. The working end of the electric suction cup is connected to the side wall of the corresponding lamp ring, and the rear end of the rotating rod passes through a rotating groove opened on the first mounting housing.

[0013] Preferably, silicone strips are bonded to the outer surfaces of the first lamp ring, the second lamp ring, and the third lamp ring, and the surface of the silicone strips is coated with adhesive.

[0014] Preferably, the transport assembly includes multiple delivery pipes connected to the input ends of the first and second nozzles. The delivery pipes are fixedly installed on the inner wall of the second mounting cylinder. The second connecting housing movably penetrates the second mounting housing. A rotating ring is fixedly sleeved on the outer wall of the second connecting housing on one side of the rear end of the second mounting housing. A first delivery port, a second delivery port, and a water outlet are sequentially installed on one side of the rotating ring. The second connecting housing has pipes inside that are respectively connected to the first delivery port, the second delivery port, and the water outlet. The pipes are respectively connected to the corresponding first and second nozzles.

[0015] Preferably, a sponge strip is glued to the end of the front end of the second mounting cylinder, and a sponge ring is glued to the outer side wall of the front end of the second mounting cylinder. The sponge strip is located inside the sponge ring, and the shape and size of the sponge ring are adapted to the annular groove.

[0016] Preferably, a notch is provided on one side of the sponge strip, and a waterproof membrane is attached to the surface of the exposed sponge ring at the notch. A conveying channel is installed in the inner wall of the second mounting cylinder, and the entrance of the conveying channel is located at the notch of the sponge strip. The end of the conveying channel away from the notch is connected to a corresponding pipe inside the second connecting housing.

[0017] Preferably, a plurality of spring rods are installed between the rotating ring and the second mounting housing on the side near the second mounting housing, and the plurality of spring rods are distributed at equal angles.

[0018] Preferably, the rear side of the rotating ring is provided with a fixed bracket that is fixedly connected to the second mounting housing, and the outer diameter of the fixed bracket at the middle position is less than or equal to the inner diameter of the rotating ring.

[0019] Compared with existing technologies, the advantages of this invention are:

[0020] 1. This invention achieves layered illumination by setting up a first, second, and third light ring. The first light ring provides focused illumination, highlighting lesion details, while the second and third light rings supplement the overall field of vision with wide-angle diffused light, reducing shadows and blind spots. Doctors can flexibly adjust the position of the light rings by rotating a lever, with high and low beams working together to avoid light source overlap and interference. This design significantly improves the clarity and contrast of observation during rectal examinations, making the boundary between lesions and normal tissues clearer.

[0021] 2. This invention uses a first mounting cylinder and a second mounting cylinder to be inserted alternately into the scope body. The friction and adhesion generated by the silicone strip and the sponge ring ensure stable and reliable installation. After the first mounting cylinder is pulled out, the lamp ring is adhered to the inner wall of the scope body by the silicone strip and will not shift. The second mounting cylinder is flexibly fixed by the sponge ring, which can both accommodate errors and prevent loosening. This structure avoids the need for complex and precise alignment, simplifies the operation process, and improves the stability of the instrument and the reliability of repeated use.

[0022] 3. This invention features a delivery pipe and nozzle inside the endoscope, allowing doctors to achieve precise disinfection and targeted medication spraying. The first nozzle can locally sterilize, while the second nozzle can spray medication evenly. The nozzle rotates and sprays simultaneously during the retraction of the endoscope, achieving dynamic coverage. The sponge strip absorbs excess disinfectant and drains it through the notch, preventing liquid accumulation. This design allows disinfection and medication administration to be completed within the same instrument, eliminating the need for frequent tool changes, improving efficiency, and reducing the risk of cross-infection.

[0023] 4. In this invention, doctors can use the connecting plate to fix the endoscope and handheld camera at the same time, achieving dual control with one hand. The other hand can rotate the nozzle or control the endoscope to retract. The entire operation does not require motor assistance, avoiding electronic delay or loss of control. Doctors can directly perceive resistance and angle, improving operational safety. The speed of endoscope retraction is synchronized with the movement of the camera, maintaining a continuous field of vision, preventing blind spots, and ensuring the continuity and controllability of the entire process of examination, disinfection, and drug administration.

[0024] 5. This invention uses inexpensive plastic material for the scope body, which can be directly discarded after use. High-value components such as the lamp ring, nozzle, and installation tube can be repeatedly removed and disinfected for reuse. This design significantly reduces the cost per operation while ensuring safety and hygiene, avoiding the problem of expensive disposable consumables in traditional anoscopes.

[0025] In summary, this invention achieves a comprehensive effect of clear observation, stable installation, convenient operation, efficient disinfection, and environmental friendliness through multi-source layered lighting, modular installation structure, integrated disinfection and drug administration, manual synchronous control, and cost-optimized design. Its design not only enhances the flexibility and safety of doctors' operations but also reduces usage costs. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Reference Figures 1 to 11 A multi-source anorectal examination endoscope for proctology includes an endoscope body 1, an endoscope core 2, a first mounting cylinder 7, and a second mounting cylinder 17. The endoscope core 2, the first mounting cylinder 7, and the second mounting cylinder 17 are inserted into the endoscope body 1 sequentially as needed during surgery. A first connecting housing 8 is fixedly connected to the rear end of the first mounting cylinder 7, and a second connecting housing 23 is fixedly connected to the rear end of the second mounting cylinder 17. The front end of the endoscope body 1 is rolled inward to form a mounting ring 15, forming an annular groove between the mounting ring 15 and the inner wall of the endoscope body 1. A protective cover 4 is fixedly installed at the rear end of the endoscope body 1, and a handle 3 is fixedly installed on the side wall of the protective cover 4. A first mounting housing 5 that mates with the first mounting cylinder 7 or a second mounting housing 21 that mates with the second mounting cylinder 17 is detachably installed at the rear end of the protective cover 4. During use, the corresponding first mounting housing 5 or second mounting housing 21 is installed as needed. Installation can be done using tape or clips, and the diameter of the second mounting cylinder 17 is slightly smaller than that of the first mounting cylinder 7.

[0040] The first mounting cylinder 7 is fitted with a first lamp ring 9, a second lamp ring 10, and a third lamp ring 11 sequentially from front to back. Multiple connecting rods 12 are provided at equal angles between the first lamp ring 9 and the second lamp ring 10, and between the second lamp ring 10 and the third lamp ring 11. Multiple rotating rods 6 are provided at equal angles on the rear side of the third lamp ring 11. Electric suction cups 13 are fixedly connected to both ends of each connecting rod 12 and the front end of each rotating rod 6. The working end of the electric suction cup 13 is connected to the side wall of the corresponding lamp ring. The electric suction cup 13 is existing technology, and its specific structural design will not be described in detail here. The rear end of the rotating rod 6 passes through the rotating groove opened on the first mounting housing 5. Silicone strips 14 are glued to the outer surfaces of the first lamp ring 9, the second lamp ring 10, and the third lamp ring 11. The surface of the silicone strips 14 is coated with glue.

[0041] A sponge strip 18 is glued to the front end of the second mounting cylinder 17. A sponge ring 29 is glued to the outer wall of the front end of the second mounting cylinder 17. The sponge strip 18 is located inside the sponge ring 29. The shape and size of the sponge ring 29 are adapted to the annular groove. The front end of the second mounting cylinder 17 is provided with a first nozzle 19 and multiple second nozzles 20. The three nozzles are distributed at equal angles. The input ends of the first nozzle 19 and the second nozzles 20 are connected to a delivery pipe 31. The delivery pipe 31 is fixedly installed on the inner wall of the second mounting cylinder 17. The second connecting housing 23 movably passes through the second mounting housing 21. A rotating ring 24 is fixedly sleeved on the outer wall of the second connecting housing 23 on one side of the rear end of the second mounting housing 21. A first delivery port 25, a second delivery port 26, and a water outlet 27 are sequentially installed on one side of the rotating ring 24. The second connecting housing 23 is provided with pipes that are respectively connected to the first delivery port 25, the second delivery port 26, and the water outlet 27. The pipes are respectively connected to the corresponding first nozzle 19, second nozzle 20, and delivery channel 30.

[0042] A notch is provided on one side of the sponge strip 18, and the surface of the exposed sponge ring 29 is covered with a waterproof membrane to prevent the sponge ring 29 from being contaminated. A conveying channel 30 is installed in the inner wall of the second mounting cylinder 17. The entrance of the conveying channel 30 is located at the notch of the sponge strip 18. The end of the conveying channel 30 away from the notch is connected to the corresponding pipe inside the second connecting housing 23. Multiple spring rods 28 are installed between the rotating ring 24 and the second mounting housing 21 on the side close to the second mounting housing 21. The multiple spring rods 28 are distributed at equal angles.

[0043] The rotating ring 24 is provided with a fixed bracket 22 fixedly connected to the second mounting housing 21. The outer diameter of the fixed bracket 22 at the middle position is less than or equal to the inner diameter of the rotating ring 24. The grip of the handheld camera 32 is connected to the handle 3 through two connecting plates 16.

[0044] Before use, the patient should first assume a lateral or knee-chest position to expose the anal area. The doctor then applies lubricant to the anoscope body 1 and the endoscope core 2 to reduce discomfort during insertion. Before insertion, the doctor uses their left thumb and forefinger to separate the gluteal cleft and expose the anus. The anoscope is then slowly and gently inserted into the anus, usually towards the navel, until it reaches a suitable position within the rectum. At this point, the first mounting cylinder 7 is pre-installed inside the anoscope body 1, located between the anoscope body 1 and the endoscope core 2. The front end of the first mounting cylinder 7 abuts against the mounting ring 15. The first mounting housing 5, connected to the first mounting cylinder 7, is fixed to the protective cover 4 with tear-off tape, ensuring that the first mounting cylinder 7 does not wobble. The endoscope core 2 is then removed, and the first lamp ring 9, second lamp ring 10, and third lamp ring 11 are adjusted using the rotating rod 6. The first lamp ring 9, the second lamp ring 10, and the third lamp ring 11 of this device are fixed inside the endoscope body 1 before insertion. After the endoscope core 2 is pulled out, the light can be adjusted immediately, which effectively reduces the subsequent light adjustment time and reduces patient discomfort.

[0045] When adjusting the lighting, first rotate the first lamp ring 9 using the rotating rod 6 to adjust its illumination position. The first lamp ring 9, located at the front end of the first mounting cylinder 7, is responsible for focusing illumination on the examination area, providing high-contrast lighting. Then, disconnect the motorized suction cup 13 that is attracted to the first lamp ring 9, and rotate the rotating rod 6 again to adjust the illumination position of the second lamp ring 10. Finally, adjust the illumination position of the third lamp ring 11 in the same way. The second and third lamp rings 10 and 11 are located in the middle and rear of the first mounting cylinder 7, with a large light divergence angle, illuminating surrounding tissue and assisting the doctor in observing the boundary between lesions and healthy tissue. Using the rotating rod 6, the illumination angles of multiple lamp rings can be flexibly adjusted according to the location of the lesion. Layered lighting eliminates the shadows produced by traditional single light sources, achieving a combination of high and low beams and preventing overlap and interference of light sources.

[0046] When adjusting the first light ring 9, the second light ring 10, and the third light ring 11, you can either observe with the naked eye or insert the camera of the handheld camera 32 into the lens body 1 through the through hole on the first mounting housing 5 for more precise lighting adjustments. After adjusting the lighting, release the electric suction cup 13 that attracts the third light ring 11, tear off the tape, hold the handle 3 with one hand, and hold the first mounting housing 5 with the other hand to slowly pull out the first mounting cylinder 7. During the pulling process, while ensuring the stability of the lens body 1, slightly move the first mounting cylinder 7 up, down, left, and right by hand to squeeze the first light ring 9, the second light ring 10, and the third light ring 11. The first light ring 9, the second light ring 10, and the third light ring 11 are all equipped with silicone strips 14. In this way, after the first mounting cylinder 7 is pulled out, the first light ring 9, the second light ring 10, and the third light ring 11 can be stuck to the inner wall of the lens body 1 by the adhesive of the silicone strips 14.

[0047] After removing the first mounting sleeve 7, repeat the previous steps to insert the second mounting sleeve 17 into the lens body 1 until the sponge strip 18 abuts against the mounting ring 15 at the end of the lens body 1. At this point, the sponge ring 29 will be squeezed into the annular groove between the lens body 1 and the mounting ring 15. The squeezed sponge ring 29 generates frictional resistance, helping to fix the position of the second mounting sleeve 17 and preventing it from accidentally loosening or shifting during use. In addition, the flexibility of the sponge ring 29 makes the installation process more error-tolerant, and assembly can be completed without extremely high-precision alignment. The diameter of the second mounting sleeve 17 is slightly smaller than that of the first mounting sleeve 7 to avoid excessive friction on the first lamp ring 9, the second lamp ring 10, and the third lamp ring 11 during insertion, which could cause them to shift. After the second mounting sleeve 17 is inserted, the second mounting housing 21 is fixed to the protective cover 4 with tear-off tape, completing the installation of the second mounting sleeve 17.

[0048] During disinfection, the disinfectant enters the first delivery port 25 through a hose, then flows through the pipe inside the second connecting housing 23 and the delivery pipe 31 fixed to the inner wall of the second mounting cylinder 17, and finally is sprayed out from the first nozzle 19. During pesticide spraying, the pesticide enters the second delivery port 26 through a hose, then flows through the pipe inside the second connecting housing 23 and the delivery pipe 31 fixed to the inner wall of the second mounting cylinder 17, and finally is sprayed out from the second nozzle 20.

[0049] Before disinfection, the doctor can insert the lens of the handheld camera 32 through the through slots on the fixing bracket 22 and the second mounting housing 21 into the scope body 1. Then, the handle 3 and the grip of the handheld camera 32 are inserted into the two connecting plates 16. At this time, the doctor only needs to hold the grip of the handheld camera 32 with one hand, while the fingers are spaced apart to clamp the connecting plates 16, which can simultaneously fix the scope body 1 and the handheld camera 32. The doctor's other hand can adjust the position of the first nozzle 19 by rotating the rotating ring 24, which can disinfect the whole area while also focusing on disinfecting severely injured areas to improve the sterilization effect. There is a notch on the sponge strip 18, and the surface of the exposed sponge ring 29 is covered with a waterproof membrane to prevent the sponge ring 29 from being contaminated. Excess disinfectant will be absorbed by the sponge strip 18 during disinfection. During disinfection, when the gap between the sponge strips 18 is at its lowest point, the doctor's other hand can press the rotating ring 24 back and forth. Through the buffer of the spring rod 28, the second mounting cylinder 17 squeezes the sponge strips 18 at a uniform speed. At this time, the squeezed disinfectant will fall into the gap between the sponge strips 18 under the action of gravity, and then flow through the delivery channel 30 and the pipe inside the second connecting shell 23 in sequence, and finally be discharged from the outlet 27, so as to avoid the sponge strips 18 becoming saturated and causing the disinfectant to accumulate in the intestine.

[0050] Similarly, when spraying the medication, the position of the second nozzle 20 can be adjusted first to focus the spray on the wound. Then, multiple second nozzles 20 can be rotated and sprayed to ensure a more even distribution of the medication. Furthermore, the medication should be sprayed while simultaneously withdrawing the anoscope until the serrated line is reached, at which point the anoscope is completely withdrawn. During this process, the doctor can slowly move the handheld camera 32 with one hand. Due to the connection plate 16, the handle 3 will also move, causing the anoscope body 1 to slowly withdraw. The other hand can rotate the rotating ring 24, causing the second nozzle 20 to rotate and spray the medication. Throughout the process, the doctor controls the slow withdrawal of the anoscope body 1 with one hand to ensure a smooth movement of the field of view, while the other hand simultaneously adjusts the angle of the second nozzle 20 to achieve dynamic medication spraying. This eliminates the need for frequent tool changes or adjustments to the grip, resulting in a smoother process. The withdrawal speed of the anoscope body 1 is matched with the movement of the handheld camera 32 to ensure a continuous field of view and avoid blind spots caused by sudden displacement. Furthermore, the entire operation requires no motor or electronic assistance. Doctors directly sense the resistance to the withdrawal of the endoscope 1 and the rotation angle of the second nozzle 20 through hand movements, avoiding the risk of delay or loss of control due to motor drive. When spraying medicine or disinfectant, a miniature air pump can be connected to the unused first delivery port 25, second delivery port 26, or outlet 27 with a hose to pump air into the intestine, slightly opening the intestinal wall. The opened intestinal wall allows the disinfectant or medicine to adhere more evenly, avoiding localized leakage due to folds.

[0051] After the medication reaches the dentate line, completely withdraw the entire anoscope, then remove the connecting plate 16, pull out the handheld camera 32, peel off the tape on the second mounting housing 21, pull out the second mounting tube 17, and finally use tools to remove the first lamp ring 9, the second lamp ring 10, and the third lamp ring 11. The plastic endoscope body 1 comes into direct contact with the patient and requires strict sterilization or disposal, while the other high-value components can be repeatedly sterilized and reused, significantly reducing the cost per operation. In addition, this device allows doctors to complete observation, sterilization, and medication administration with just two hands, making operation simple and efficient, reducing complex mechanical adjustments or cumbersome procedures.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
