Abstract
Description
Technical Field
[0001] This invention relates to the field of tumor volume detection technology, and more specifically to a tumor volume detection device for gastrointestinal endoscopy based on TOF technology. Background Technology
[0002] In recent years, with the development of digestive endoscopy technology, gastroscopy and colonoscopy have become one of the most important diagnostic and treatment methods for digestive system diseases, especially digestive tract tumors. Gastroscopy and colonoscopy can detect many digestive tract tumors, including early malignant tumors, smooth tumors, lipomas, and polyps, etc.
[0003] A gastrointestinal endoscope is a thin, flexible tube inserted through the esophagus into the stomach and duodenum. During this process, doctors can directly observe the inside of the esophagus, stomach, and duodenum, accurately locate suspicious lesions, and perform pathological biopsies and cytological examinations. Especially for lesions in minute locations, gastroscopy provides accurate diagnosis.
[0004] However, a limitation of current gastroscopy and colonoscopy remains unresolved: the inability to objectively assess tumor size during the procedure. Currently, size assessment relies solely on the subjective experience of the examining physician, resulting in inconsistent reliability. Furthermore, post-operative tumor size measurements may differ from the original tumor size due to traction during surgery and specimen shrinkage. Since tumor size plays a crucial role in determining malignancy, benignity, and staging, a method for accurately measuring tumor size is needed during gastroscopy and colonoscopy. Summary of the Invention
[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a tumor volume detection device for gastrointestinal endoscopy based on Time-of-Flight (TOF) technology. An electric telescopic rod drives a toothed plate to retract, and the toothed plate, through meshing with gears, drives a drive shaft and a support plate to rotate, positioning the TOF sensor between two illumination sources. The tumor mass is then irradiated by these sources. During irradiation, the TOF sensor calculates the time difference between the time of light emission and the time of light reflection to measure the size of the tumor mass. The overall structure facilitates the measurement of tumor mass size, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a tumor volume detection device for gastrointestinal endoscopy based on TOF technology, comprising a gastrointestinal endoscope body, wherein the front end of the gastrointestinal endoscope body includes a CCD cable, two illumination sources, an air supply pipe, a water supply pipe, and a forceps pipe, wherein the air supply pipe and the water supply pipe are located between the two illumination sources, the CCD cable is located at the top of the forceps pipe, a mounting plate is sleeved on the front end of the gastrointestinal endoscope body, the inner wall of the mounting plate is fixedly connected to the outer wall of the front end of the gastrointestinal endoscope body, a support mechanism is fixedly provided on the front side of the top of the mounting plate, a TOF sensor is provided inside the support mechanism, and an adjustment mechanism is provided outside the TOF sensor;
[0007] The support mechanism includes a first mounting plate and a second mounting plate, both of which are located on the front side of the mounting plate. The first mounting plate is fixedly connected to the front side of the mounting plate. An arc-shaped groove and a mounting groove are provided on the side of the first and second mounting plates that are close to each other. The bottom ends of the two mounting grooves pass through the first and second mounting plates respectively. The arc-shaped groove is located at the top of the mounting groove and is connected to the mounting groove. A positioning column is fixedly provided inside the mounting groove. The TOF sensor is located between the two mounting grooves. The first mounting plate and the second mounting plate are connected by bolts, which facilitates the user to disassemble and install the first and second mounting plates.
[0008] The first mounting plate has multiple connecting grooves on its front side, and the second mounting plate has multiple connecting holes through its interior. The multiple connecting grooves correspond to the positions of the multiple connecting holes in the front and back respectively. A bolt is provided on the front side of the connecting hole, and the rear end of the bolt passes through the connecting hole and extends into the connecting groove. The bolt and the connecting groove are threaded together. Through the cooperation of the bolt and the connecting groove, the second mounting plate can be tightly connected to the first mounting plate. At the same time, the second mounting plate can be disassembled by removing the bolt.
[0009] The adjustment mechanism includes an electric telescopic rod located between two arc-shaped grooves. A positioning plate is fixedly mounted on one end of the electric telescopic rod. A toothed plate is located at the bottom of the end of the electric telescopic rod near the positioning plate, between two mounting grooves. The bottom end of the positioning plate is fixedly connected to the top end of the toothed plate. A drive shaft is located at the bottom of the end of the toothed plate away from the positioning plate. Movable grooves are opened at both ends of the drive shaft. Two positioning posts extend into the two movable grooves respectively. Gears are fixedly sleeved on the outer walls of both ends of the drive shaft. The top of the gears meshes with the bottom end of the toothed plate. A support plate is fixedly mounted on the side of the drive shaft near the toothed plate, between the two gears. A groove is opened on the front side of the end of the support plate away from the drive shaft. The TOF sensor is installed inside the groove. When the electric telescopic rod is activated, the toothed plate retracts. During the retraction of the toothed plate, it drives the drive shaft to rotate through meshing with the gears. At the same time, the rotation of the drive shaft also drives the support plate to rotate, and during the rotation, the TOF sensor is rotated between the two lighting sources.
[0010] In a preferred embodiment, a vertical plate is fixedly provided at the bottom of one end of the support plate near the drive shaft. The vertical plate is located between two mounting slots, and the bottom end of the vertical plate passes through the mounting slot and extends to the bottom of the mounting slot. A scraper is fixedly provided at the bottom end of the vertical plate, and the rear end of the scraper contacts the front end of the endoscope body. The rotation of the support plate can also drive the vertical plate and the scraper to rotate. During the rotation, the scraper can clean the front end surface of the endoscope body, thereby providing a better environment for the illumination source to be illuminated.
[0011] In a preferred embodiment, the scraper is made of rubber material, which has certain anti-corrosion and moisture-proof properties, thus extending the service life of the invention.
[0012] In a preferred embodiment, the outer walls of the mounting plate, the first mounting plate, and the second mounting plate are all arc-shaped. By making the outer walls of the mounting plate, the first mounting plate, and the second mounting plate arc-shaped, damage to the patient's internal organs can be avoided during use.
[0013] In a preferred embodiment, the diameter between the two arc-shaped grooves is greater than the diameter between the two mounting grooves. By setting the diameter between the two arc-shaped grooves to be greater than the diameter between the two mounting grooves, the installed electric telescopic rod will not fall into the mounting groove, thereby improving the stability of the overall structure.
[0014] The technical effects and advantages of this invention are as follows:
[0015] This invention uses an electric telescopic rod to retract a toothed plate, which in turn rotates a drive shaft and a support plate by meshing with a gear. This rotates the TOF sensor between two illumination sources, which then irradiate the tumor mass. During the irradiation process, the TOF sensor calculates the time difference between the time the light is emitted and the time the light is reflected back to measure the size of the tumor mass. The overall structure facilitates the measurement of the size of the tumor mass.
[0016] The present invention drives the vertical plate and scraper to rotate by rotating the support plate. During the rotation, the scraper can clean the front surface of the endoscope body, allowing the illumination source to have a better environment for illumination and avoiding the obstruction of the illumination source by dirt inside the patient.
[0017] This invention allows for the disassembly of the second mounting plate by removing the bolts, facilitating user maintenance and replacement of the internal structure. The arc-shaped groove provides a limiting and fixing mechanism for the electric telescopic rod, while the positioning post, in conjunction with the movable groove, limits and fixes the drive shaft. The overall structure facilitates the installation and disassembly of the electric telescopic rod and drive shaft, and the bolts provide a fixing and limiting mechanism for the entire structure.

[0028] Refer to the instruction manual appendix Figure 1-8This embodiment discloses a tumor volume detection device for gastrointestinal endoscopy based on Time-of-Flight (TOF) technology, comprising a gastrointestinal endoscope body 1. The front end of the endoscope body 1 includes a CCD cable 2, two illumination sources 3, an air supply pipe 4, a water supply pipe 5, and a forceps pipe 6. The air supply pipe 4 and water supply pipe 5 are located between the two illumination sources 3. The CCD cable 2 is located at the top of the forceps pipe 6.

A support mechanism is fixedly mounted on the front side of the top of the mounting plate 7. A TOF sensor 8 is located inside the support mechanism. An adjustment mechanism is located outside the TOF sensor 8. The adjustment mechanism includes an electrically telescopic rod 17. The rod 17 is located between two arc-shaped grooves 11. A positioning plate 18 is fixedly mounted on one end of the electric telescopic rod 17. A toothed plate 19 is located at the bottom of the end of the electric telescopic rod 17 closest to the positioning plate 18. The toothed plate 19 is located between two mounting grooves 12. The bottom end of the positioning plate 18 is fixedly connected to the top end of one end of the toothed plate 19. A drive shaft 20 is located at the bottom of the end of the toothed plate 19 furthest from the positioning plate 18. Movable grooves 21 are opened at both ends of the drive shaft 20. Two positioning posts 13 extend into the two movable grooves 21 respectively. Gears 22 are fixedly sleeved on the outer walls of both ends of the drive shaft 20. The top end of the gear 22 meshes with the bottom end of the toothed plate 19. A support plate 23 is fixedly mounted on the side of the drive shaft 20 closest to the toothed plate 19. Located between two gears 22, the support plate 23 has a groove 24 on its front side at the end away from the drive shaft 20. The TOF sensor 8 is installed inside the groove 24. When the electric telescopic rod 17 is activated, the gear plate 19 retracts. During the retraction of the gear plate 19, it drives the drive shaft 20 to rotate through meshing with the gears 22. At the same time, the drive shaft 20 rotates, which also drives the support plate 23 to rotate. During the rotation, the TOF sensor 8 is rotated between the two lighting sources 3.

A scraper is fixedly provided at the bottom end of the vertical plate 25. 26. The rear end of the scraper 26 contacts the front end of the endoscope body 1. The rotation of the support plate 23 also drives the vertical plate 25 and the scraper 26 to rotate. During the rotation, the scraper 26 can clean the front surface of the endoscope body 1, thereby providing a better environment for the illumination source 3 to be irradiated. The scraper 26 is made of rubber material, which has certain anti-corrosion and moisture-proof properties, thus extending the service life of the invention. The outer walls of the mounting plate 7, the first mounting plate 9, and the second mounting plate 10 are all arc-shaped. By making the outer walls of the mounting plate 7, the first mounting plate 9, and the second mounting plate 10 arc-shaped, damage to the patient's internal organs can be avoided during use. The diameter between the two arc-shaped grooves 11 is larger than the diameter between the two mounting grooves 12.By setting the diameter between the two arc-shaped grooves 11 to be larger than the diameter between the two mounting grooves 12, the installed electric telescopic rod 17 will not fall into the mounting groove 12, thus improving the overall structural stability.
[0029] The specific implementation scenario is as follows: When medical staff use this invention, they insert the gastrointestinal endoscope body 1 into the patient's body, and then activate the electric telescopic rod 17 to drive the toothed plate 19 to retract. During the retraction of the toothed plate 19, it drives the drive shaft 20 to rotate through the meshing of the gear 22. At the same time, the drive shaft 20 also drives the support plate 23 to rotate. During the rotation, the TOF sensor 8 is rotated between the two illumination sources 3, and then the tumor is irradiated by the illumination sources 3. During the irradiation, the TOF sensor 8 measures the size of the tumor by calculating the time difference between the time of light irradiation and the time of light reflection. At the same time, the rotation of the support plate 23 also drives the vertical plate 25 and the scraper 26 to rotate. During the rotation, the scraper 26 can clean the front surface of the gastrointestinal endoscope body 1, thereby providing a better environment for the illumination source 3 to be irradiated. The overall structure facilitates the measurement of the size of the tumor.
