Abstract
Description
Technical Field
[0001] This invention relates to the field of tumor volume detection technology, specifically to a tumor volume detection device for gastrointestinal endoscopy based on TOF technology. Background Technology
[0002] Early screening and precision diagnosis of gastrointestinal tumors are important research directions in the medical field. Tumor volume, as a core indicator for assessing disease progression, developing individualized treatment plans, and monitoring treatment effectiveness, is crucial for accurate clinical decision-making. Gastrointestinal endoscopy, using a thin, flexible tube inserted through the esophagus into the stomach and duodenum, allows direct observation of the internal structures of the esophagus, stomach, and duodenum, enabling the identification of suspicious lesions and the performance of pathological biopsies and cytological examinations. It is a core tool for the screening and diagnosis of gastrointestinal tumors.
[0003] Tumor size plays a crucial role in determining tumor benignity, malignancy, and staging. However, current gastroscopy and colonoscopy examinations often rely heavily on the subjective experience of the examining physician to judge tumor size. Differences in observation angles and experience levels among different physicians lead to insufficient reliability and consistency in measurement results. Furthermore, in clinical practice, the size of the specimen is often measured after resection to supplement the assessment. However, factors such as traction during surgery and natural shrinkage of the specimen after removal from the body can cause deviations between postoperative measurements and the actual size of the tumor within the body. This results in the inability to accurately obtain the true volume data of the tumor within the body, affecting the assessment of the condition. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a tumor volume detection device for gastrointestinal endoscopy based on TOF technology, which solves the problem that traditional gastrointestinal endoscopy cannot accurately obtain the true volume data of tumors in the body, thus affecting the assessment of the condition.

[0016] Working Principle: Image signals are transmitted via a CCD cable. A clamp tube facilitates operation, an air supply pipe supplies air, a water supply pipe supplies water, and an illumination source provides light. A motor drives a worm gear, which in turn rotates bevel gears two and three, causing a reciprocating screw to rotate within the mounting block. This allows a scraper to clean the probe head. Bevel gear three drives shaft two to rotate, and an electric actuator, via an arc-shaped slider, moves a movable plate on shaft two. When the internal gear ring meshes with the gear, the movable plate rotates around shaft two within the mounting block, adjusting the position of the TOF sensor. When the electric actuator moves the movable plate, the internal gear ring disengages from shaft two, and arc-shaped rack one meshes with arc-shaped rack two, limiting the movable plate on the mounting block. This allows the TOF sensor's position on the mounting block to be adjusted according to detection requirements, facilitating detection.
[0017] By utilizing the rotation of the worm gear, the arc-shaped cam can rotate around the worm gear as its center, causing the sealing block one to no longer be in contact with the limiting ring one, thereby allowing water to flow through the connecting pipe three. The connecting pipe four then transports the water from the water supply pipe to the scraper, which sprays out through the nozzles on the scraper. Furthermore, the worm gear drives the blades to rotate, allowing the water to enter the nozzles more quickly. This achieves the goal of ensuring that water is only sent into the nozzles through the connecting pipe four for thorough cleaning when the scraper is moving and cleaning, thus enhancing cleaning efficiency.
[0018] When the moving plate moves along the rotating shaft two, it drives the top column to move within the connecting pipe two, causing the sealing block two to move away from the limiting ring two. This allows the gas in the connecting pipe two to flow into the connecting pipe one, and the gas in the connecting pipe one to enter the air bladder through the valves, causing the air bladder to inflate to different degrees. This allows adjustment of the horizontality of the mounting plate on the moving plate, and in turn, adjustment of the angle of the TOF sensor on the mounting plate. This enables the TOF sensor to perform multi-dimensional detection of tumors in different locations and shapes within the gastrointestinal lumen, enhancing the comprehensiveness of the detection. Real-time cleaning ensures a clear detection field, and the sensor position and angle can be adjusted to adapt to different tumor shapes, thereby obtaining the true volume data of the tumor in the body.
[0019] This invention provides a tumor volume detection device for gastrointestinal endoscopy based on Time-of-Flight (TOF) technology. It has the following beneficial effects:
[0020] 1. This invention enables a scraper to clean one side of the probe head by adjusting the limiting structure. The water spray structure enhances cleaning efficiency during scraping. The adjusting limiting structure allows the TOF sensor to be positioned on the mounting block as needed, and the angle adjustment structure allows for angle adjustment. The TOF sensor is used to measure the size of the tumor mass, thus ensuring a clear detection field through real-time cleaning. By adjusting the sensor position and angle to adapt to different tumor morphologies, the true volume data of the tumor in the body can be obtained. This solves the problem that traditional gastroscopy and colonoscopy cannot accurately obtain the true volume data of the tumor in the body, which affects the assessment of the condition.
[0021] 2. This invention uses a motor to drive a worm gear to rotate a bevel gear, which in turn allows the scraper to be moved by a reciprocating screw to clean the probe head. It also allows the position of the moving plate to be adjusted through the meshing of the gear and the internal gear ring, and the arc rack one and the arc rack two. This enables the TOF sensor to be adjusted on the mounting block according to the detection requirements, thus enhancing its practicality.
[0022] 3. This invention utilizes the rotation of a worm gear to move an arc-shaped cam, which in turn moves a sealing block, allowing water to circulate within the connecting pipe and be sprayed out through nozzles on the scraper. The paddles further facilitate the rapid entry of water into the nozzles, assisting the scraper in performing a comprehensive cleaning operation. This ensures that water is only delivered through the connecting pipe to the nozzles during scraping operations, quickly removing mucus, blood, and other stains scraped away by the scraper. This prevents stains from remaining or re-adhering to the detection area of the probe, ensuring a clear field of view and enhancing cleaning efficiency and thoroughness.
[0023] 4. This invention utilizes an electric actuator to not only move the movable plate, thereby adjusting and fixing the position of the TOF sensor, but also uses the cooperation between the top column and the sealing block two to allow the gas in the air delivery pipe to inflate the airbag as needed, adjusting the level of the TOF sensor on the movable plate for more comprehensive angle detection.

Detailed Implementation
[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] Please see the appendix Figure 1 -Appendix Figure 12This invention provides a tumor volume detection device for gastrointestinal endoscopy based on TOF technology, including a gastrointestinal endoscope body 1. A probe head 2 is installed on one side of the gastrointestinal endoscope body 1. A CCD cable 4, a forceps tube 6, an air supply tube 7, and a water supply tube 8 are sequentially installed inside the probe head 2. An illumination source 5 is symmetrically installed in the middle of the probe head 2. A mounting block 3 is fixedly connected to one side of the probe head 2. An adjustment and limiting structure is fixedly installed on one side of the mounting block 3. A scraper 9 is provided on one side of the adjustment and limiting structure. One side of the scraper 9 is slidably connected to the inside of the mounting block 3. A water spray structure is fixedly connected to the top of the scraper 9. A moving plate 10 is slidably connected to the inner wall of the mounting block 3. An angle adjustment structure is provided inside the moving plate 10. A TOF sensor 12 is installed on one side of the angle adjustment structure.
[0028] Specifically, image signals are transmitted via CCD cable 4, pliers tube 6 facilitates pliers operation, air supply pipe 7 facilitates air supply, water supply pipe 8 facilitates water supply, and lighting source 5 provides illumination. The mounting block 3 mounts all components. Adjusting the limiting structure allows the scraper 9 to slide up and down on the mounting block 3, cleaning one side of the probe head 2. Simultaneously, a water spray structure on the scraper 9 sprays water concurrently with cleaning, enhancing efficiency. The adjusting limiting structure also allows the moving plate 10 to move within the mounting block 3, thereby adjusting the angle of the internal structure of the moving plate 10. The corresponding movement allows the TOF sensor 12 to adjust its position on the mounting block 3 as needed, and to make certain angle adjustments through the angle adjustment structure. This enables the TOF sensor 12 to measure the size of the tumor mass by calculating the time difference between the time of light irradiation and the time of light reflection, thus enhancing the accuracy and flexibility of detection. It integrates cleaning and tumor volume measurement in gastroscopy and colonoscopy, ensuring a clear detection field through real-time cleaning, and adapting to different tumor morphologies through sensor position and angle adjustment, thereby obtaining the true volume data of the tumor in the body. This solves the problem that traditional gastroscopy and colonoscopy cannot accurately obtain the true volume data of the tumor in the body, which affects the assessment of the condition.
[0029] Please see the appendix Figure 5 Appendix Figure 6 Appendix Figure 9 Appendix Figure 10The adjusting limit structure includes a motor 19, one side of which is fixedly mounted on one side of the mounting block 3. A worm gear 20 is fixedly connected to the output end of the motor 19. A worm wheel 26 is meshed with the teeth of the worm gear 20. A rotating shaft 21 is fixedly connected to the middle of the worm wheel 26. One end of the rotating shaft 21 is rotatably connected to the inside of the mounting block 3, and the other end is fixedly connected to a bevel gear 23. A fixing block 22 is rotatably connected to the outer wall of the rotating shaft 21. One side of the fixing block 22 is fixedly connected to the inner wall of the mounting block 3. A bevel gear 33 and a bevel gear 34 are sequentially meshed with the teeth of the bevel gear 23. A reciprocating screw 24 is fixedly connected to the middle of the bevel gear 33. Both ends of the reciprocating screw 24 are rotatably connected to the inside of the mounting block 3. An arc-shaped rack 38 is fixedly connected to one side of the mounting block 3. The outer wall of the reciprocating screw 24 is mounted on one side of the scraper 9. An electric actuator 39 is fixedly installed on one side of the fixed block 22. An arc-shaped slider 41 is fixedly connected to the output end of the electric actuator 39. The outer wall of the arc-shaped slider 41 is slidably connected to the inside of the moving plate 10. An arc-shaped rack 37 is fixedly connected to the side of the moving plate 10 away from the arc-shaped slider 41. The tooth end of the arc-shaped rack 37 can mesh with the tooth end of the arc-shaped rack 38. A rotating shaft 35 is fixedly connected to the middle of the bevel gear 34. A gear 36 is fixedly connected to the outer wall of the rotating shaft 35. One end of the rotating shaft 35 is rotatably connected to the inside of the mounting block 3. One side of the rotating shaft 35 is slidably connected to one side of the moving plate 10. An internal gear ring 40 is fixedly connected to the side of the moving plate 10 near the gear 36. The tooth end of the internal gear ring 40 can mesh with the tooth end of the gear 36.
[0030] Specifically, the operation of motor 19 drives worm gear 20 to rotate, which in turn drives worm wheel 26 to rotate, causing shaft 21 to rotate on mounting block 3 and inside fixed block 22, which in turn drives bevel gear 23 to rotate, causing bevel gear 33 and bevel gear 34 to rotate, which in turn causes reciprocating screw 24 to rotate inside mounting block 3, causing scraper 9 to slide back and forth inside mounting block 3 to clean probe head 2.
[0031] The rotation of bevel gear 34 drives the rotation of shaft 35, which in turn drives gear 36 to rotate synchronously. When the electric actuator 39 is running, the moving plate 10 restricts the arc-shaped slider 41, allowing the electric actuator 39 to drive the moving plate 10 to move on shaft 35 via the arc-shaped slider 41. This, in turn, drives the internal gear ring 40 to move, and prevents the arc-shaped rack 37 on the moving plate 10 from meshing with the arc-shaped rack 38. Thus, when the internal gear ring 40 meshes with gear 36 on shaft 35... When connected, the movable plate 10 can rotate within the mounting block 3 with the pivot 35 as the center, thereby driving the angle adjustment structure and the TOF sensor 12 on the movable plate 10 to move with the pivot 35 as the center, adjusting the position of the TOF sensor 12 on the mounting block 3. When the movable plate 10 rotates with the pivot 35 as the center, the sliding between the arc-shaped slider 41 and the movable plate 10 will not affect the rotation of the movable plate 10, and the movable plate 10 can be moved.
[0032] When the electric actuator 39 moves the arc-shaped slider 41, causing the moving plate 10 to move in the opposite direction on the rotating shaft 35, the internal gear ring 40 disengages from the rotating shaft 35, and the arc-shaped rack 37 on the side of the moving plate 10 away from the arc-shaped slider 41 meshes with the arc-shaped rack 38 on the mounting block 3, thereby limiting the moving plate 10 on the mounting block 3. This allows the position of the TOF sensor 12 on the mounting block 3 to be adjusted according to the detection requirements, facilitating detection. Furthermore, the motor 19 drives the worm gear 20 to rotate the bevel gear 23, which allows the scraper 9 to be moved by the reciprocating screw 24 to clean the probe head 2. The meshing between the gear 36 and the internal gear ring 40, and between the arc-shaped rack 37 and the arc-shaped rack 38, adjusts the position of the moving plate 10, allowing the TOF sensor 12 to be adjusted on the mounting block 3 according to the detection requirements, thus enhancing practicality.
[0033] Please see the appendix Figure 4 -Appendix Figure 8The water spray structure includes a connecting pipe 18 and an arc-shaped cam 30. One end of the connecting pipe 18 is fixedly connected to one side of the water supply pipe 8, and the other end of the connecting pipe 18 is rotatably connected to the outer wall of the worm gear 20. A connecting pipe 25 is fixedly connected to one side of the connecting pipe 18, and one end of the connecting pipe 25 is fixedly connected to the top of the scraper 9. Spray holes 16 are evenly distributed inside the scraper 9. The outer wall of the connecting pipe 18 is fixedly connected to the inside of the probe head 2. A limit ring 28 is fixedly connected to the inner wall of the connecting pipe 18. A spring 31 is symmetrically fixedly connected inside the limit ring 28. A sealing block 29 is fixedly connected to one end of the spring 31. A guide post 32 is symmetrically fixedly connected to one side of the sealing block 29. The outer wall of the guide post 32 is slidably connected inside the limit ring 28. One side of the arc-shaped cam 30 is fixedly connected to one end of the worm 20. The outer wall of the worm 20 is uniformly fixedly connected with blades 27, which are located inside the connecting pipe 18. The side of the arc-shaped cam 30 away from the worm 20 is set on one side of the sealing block 29.
[0034] Specifically, the spring 21 ensures that the sealing block 29 fits against the limiting ring 28, preventing uncontrolled water flow from the connecting pipe 3 18 into the connecting pipe 4 25 and the spray nozzle 16. This avoids water spraying in unclean conditions interfering with the endoscope's field of vision or wasting water resources. The rotation of the worm gear 20 causes the arc-shaped cam 30 to rotate around the worm gear 20, which in turn moves the sealing block 29, preventing it from fitting against the limiting ring 28. The guide post 32 ensures smoother movement of the sealing block 29, allowing water to flow freely within the connecting pipe 3 18. Connector 3 18 connects water supply pipe 8 to connecting pipe 4 25. Water from water supply pipe 8 is delivered to scraper 9 via connecting pipe 4 25 and sprayed out through nozzles 16 on scraper 9. The blades 27 allow water to enter nozzles 16 more quickly, thus assisting scraper 9 in performing a comprehensive cleaning operation. This ensures that water is only delivered to nozzles 16 via connecting pipe 4 25 when scraper 9 is moving to clean, quickly rinsing away mucus, blood, and other stains scraped by scraper 9. This prevents stains from remaining or re-adhering to the detection area of probe head 2, ensuring a clear field of view and enhancing cleaning efficiency and thoroughness.
[0035] Please see the appendix Figure 2 Appendix Figure 3 Appendix Figure 5 Appendix Figure 9 -Appendix Figure 12The angle adjustment structure includes a connecting pipe 15 and a top column 42. The outer wall of the connecting pipe 15 is fixedly connected to the inside of the moving plate 10. An airbag 14 is symmetrically fixedly connected to one side of the moving plate 10. One side of the airbag 14 is located on one side of the connecting pipe 15. A valve is provided between the connecting pipe 15 and the airbag 14. A mounting plate 11 is fixedly connected to the side of the airbag 14 away from the moving plate 10. A spring 13 is uniformly fixedly connected to one side of the mounting plate 11. One end of the spring 13 is fixedly connected to one side of the moving plate 10. The other side of the mounting plate 11 is mounted on one side of the TOF sensor 12. One end of the top post 42 is fixedly connected to one side of the movable plate 10. One end of the connecting pipe 15 is fixedly connected to the connecting pipe 2 17. One end of the connecting pipe 2 17 is fixedly connected to one side of the air supply pipe 7. The outer wall of the connecting pipe 2 17 is fixedly connected to the inside of the fixing block 22. The top post 42 is located inside the connecting pipe 2 17. The inner wall of the connecting pipe 2 17 is fixedly connected to the limiting ring 2 44. The inside of the limiting ring 2 44 is uniformly slidably connected to the guide post 2 47. One end of the guide post 2 47 is fixedly connected to the sealing block 2 43. The other end of the guide post 2 47 is fixedly connected to the limiting plate 46. One side of the limiting plate 46 is fixedly connected to the spring 3 45. One end of the spring 3 45 is fixedly connected to one side of the limiting ring 2 44.
[0036] Specifically, the mounting plate 11 is mounted on the moving plate 10 using an airbag 14 and multiple springs 13. The TOF sensor 12 is then mounted on the mounting plate 11. The air supply pipe 7 is connected to the connecting pipe 15 via a connecting pipe 2 17, facilitating the delivery of gas into the connecting pipe 15. This allows the gas in the connecting pipe 15 to enter the airbag 14 through valves according to the angle adjustment requirements, causing the airbag 14 to inflate to different degrees. This adjusts the levelness of the mounting plate 11 on the moving plate 10, thereby adjusting the angle of the TOF sensor 12 on the mounting plate 11. This enables the TOF sensor 12 to perform multi-dimensional detection of tumors in different locations and shapes within the gastrointestinal lumen, enhancing the comprehensiveness of the detection.
[0037] By setting the spring 3 45, the sealing block 2 43 can fit against the limiting ring 2 44, preventing uncontrolled gas from flowing into the connecting pipe 1 15 in the connecting pipe 2 17, avoiding unexpected expansion of the airbag 14 that would cause the TOF sensor 12 to shift angle, ensuring stable initial detection posture. Furthermore, when the moving plate 10 moves on the rotating shaft 2 35, it drives the top column 42 to move within the connecting pipe 2 17, causing one end of it to abut against the sealing block 2 43, moving the sealing block 2 43 away from the limiting ring 2 44, and driving the guide column 2... 47 slides within the limiting ring 44, causing the limiting disc 46 to compress the spring 45, allowing the gas in the connecting pipe 17 to flow into the connecting pipe 15. Thus, by using the electric push rod 39, not only can the moving plate 10 be moved to adjust and limit the position of the TOF sensor 12, but also the cooperation between the top column 42 and the sealing block 43 can allow the gas in the air supply pipe 7 to inflate the airbag 14 as needed, adjusting the level of the TOF sensor 12 on the moving plate 10 for more comprehensive angle detection.
[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
