Description

Technical Field

[0001] The present invention relates to the technical field of tumor volume detection, and in particular to a tumor volume detection device for gastrointestinal endoscopy based on TOF technology. Background Art

[0002] As a new type of medical imaging equipment, gastroenteroscopy based on TOF (Time of Flight) technology has been gradually applied to the early diagnosis and detection of gastrointestinal tumors in recent years. Unlike traditional gastroenteroscopy, TOF technology can accurately calculate the distance and volume of the target object and provide more detailed tumor information by measuring the time difference from the laser being emitted from the source to the surface of the object and returning. Most existing gastroenteroscopy devices rely on traditional imaging technologies, such as white light imaging or fluorescence imaging. Although they can provide images of the gastrointestinal tract, they have low detection accuracy for tumor volume and details. With the advancement of medical imaging technology, more and more studies have begun to try to combine TOF sensors with gastroenteroscopy to improve the depth and accuracy of detection.

[0003] Although existing TOF technology provides more accurate measurements and clearer imaging for gastroenteroscopes, traditional systems still face some challenges. Existing gastroenteroscopes usually use a laser light source with a fixed focal length. This light source design cannot automatically adjust the focal length according to different tumor depths or locations, resulting in the laser being unable to accurately focus on the target area, affecting the TOF sensor's ability to obtain high-quality reflected signals, thereby affecting the accuracy of tumor volume measurement. In addition, during the actual use of the gastroenteroscope, foreign matter or mucus is easily attached to the surface of the detection head. These attachments may not only interfere with the image quality, but also affect the TOF sensor's reception of reflected signals, thereby reducing the effectiveness of tumor detection. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a tumor volume detection device for gastroenteroscopy based on TOF technology, which solves the problem that the existing gastroenteroscopy equipment cannot flexibly adjust the laser focal length and clean foreign matter on the surface of the detection head, thereby affecting the accuracy of tumor volume detection.

This innovative cleaning method not only reduces the complexity of manual operation, but also avoids the impact of equipment contamination on detection results. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 The embodiment of the present invention provides a gastrointestinal endoscopic tumor volume detection device based on TOF technology, comprising:

[0037] The gastrointestinal endoscope body 1 is used as a gastrointestinal endoscope detection body for detecting the internal stomach and intestines of a patient;

[0038] An inner tube 2 is arranged on one side of the gastroenteroscope body 1 and is used to be inserted into the patient's body for use;

[0039] A detection head 3, which is arranged at the end of the inner measuring tube 2 away from the gastroscope body 1, and is responsible for detecting tumors;

[0040] An air supply passage 4, which is arranged inside the detection head 3 and is used for conveying water flow;

[0041] A water supply passage 5, which is arranged on one side of the gas supply passage 4 and is used for conveying gas;

[0042] An illumination passage 6, which is arranged on both sides of the detection head 3 and is used to provide a passage for the light source;

[0043] A zoom mechanism, which is arranged inside the irradiation passage 6 and is used to adjust the irradiation focal length of the light source according to the specific environment;

[0044] A forceps passage 7, which is arranged inside the detection head 3 and is used to provide a forceps delivery passage;

[0045] A fixing block 29, which is arranged on the top of the detection head 3 and is used to extend and retract the TOF sensor 32;

[0046] The zoom mechanism includes a fixed column 8, a plurality of fixed columns 8 are provided and all are fixed inside the detection head 3, the outer wall of the fixed column 8 is sleeved with a spring 9, one end of the spring 9 is fixed inside the detection head 3, a fixed frame 10 is fixed to the other end of the spring 9 on one side, the fixed frame 10 is slidably connected to the outer wall of the fixed column 8 on one side, a motor 11 is provided inside the fixed frame 10, the output end of the motor 11 is fixedly connected to a rotating shaft 12, the rotating shaft 12 is rotatably connected to the inside of the fixed frame 10, and a gear 13 is fixedly connected to the outer wall of the rotating shaft 12;

[0047] A fixed plate 14 is provided inside the detection head 3, and the fixed plate 14 is slidably connected to the outer wall of the fixed column 8 on the other side, one end of the spring 9 on the other side is fixed to the bottom of the fixed plate 14, and a rotating shaft 2 15 is rotated inside the fixed plate 14. An electric push rod 21 is provided inside the detection head 3, and the output end of the electric push rod 21 is fixed to the top of the fixed plate 14;

[0048] A second gear 16 is fixed to the outer wall of the second rotating shaft 15 , an outer ring 17 is fixed to the outer wall of the second rotating shaft 15 via a connecting rod, and lenses 18 distributed in a ring array are fixed inside the outer ring 17 .

[0049] Specifically, when it is necessary to detect a tumor in a patient's body, we need to place the inner measuring tube 2 together with the detection head 3 in the patient's body. After the detection head 3 reaches the predetermined tumor area, the laser system installed inside it will automatically start. Through the precise action of the laser, combined with the high-definition camera at the position of the detection head 3, the surrounding environment of the tumor position is analyzed in real time, providing key data support for the focal length adjustment of the device light source. At this time, the motor 11 starts and drives the shaft 12 to rotate, and the shaft 12 then drives the gear 13 to rotate synchronously. The gear 13 meshes with the gear 2 16, so that the shaft 2 15 drives the outer ring 17 to achieve precise rotation. The rotation of the outer ring 17 will adjust the position of the annularly distributed lens 18 so that it is at the optimal angle to meet the detection requirements.

[0050] When the lens 18 is adjusted to the predetermined position, the motor 11 automatically stops rotating, and the electric push rod 21 starts to start. The power of the push rod pushes the fixed plate 14 downward, and the fixed plate 14 is connected to the fixed frame 10 through the components to ensure that the fixed frame 10 and the fixed plate 14 can descend synchronously. After this series of adjustments, the determined lens 18 will be accurately positioned at the center of the laser, so that the light source is concentrated to the target area through reflection, ensuring that the laser can be efficiently received by the TOF sensor 32 deployed by the scraper 31 driven by the motor 2 30. The TOF sensor 32 will collect the reflected signal in real time and accurately calculate the size and position of the tumor, providing an accurate basis for diagnosis.

[0051] Please refer to the attached Figure 2 and attached Figure 5 A hollow cylinder 19 rotates inside the fixed plate 14, a rotating shaft 22 is fixed inside the hollow cylinder 19, a gear 20 is fixed to the outer wall of the rotating shaft 22, the gear 20 is meshed with the gear 2 16, and a fan 23 is fixed to the rotating shaft 22 coaxially;

[0052] A gas delivery pipe 1 24 is fixed at one end of the hollow cylinder 19, and a gas storage ring 25 is fixed at one end of the gas delivery pipe 1 24 away from the hollow cylinder 19. The gas storage ring 25 is fixed to the outer wall of the detection head 3, and gas delivery pipes 26 distributed in a ring array are fixed inside the gas storage ring 25;

[0053] A pressure ring 27 is fixed to one end of the gas delivery pipe 26 away from the gas storage ring 25 . The pressure ring 27 is fixed to the outer wall of the detection head 3 . Gas nozzles 28 distributed in a ring array are arranged inside the pressure ring 27 .

[0054] Specifically, before adjusting the focal length, the motor 11 starts the drive system and drives the gear 2 16 to rotate. The gear 2 16 is connected to the gear 3 20 by meshing. Because different gear ratios are set between the gear 2 16 and the gear 3 20, the speed of the gear 3 20 is significantly higher than that of the gear 2 16. This efficient transmission mechanism can quickly drive the rotating shaft 3 22 to rotate, and the rotation of the rotating shaft 3 22 directly drives the fan 23 to run at a high speed. During the rotation process, the fan 23 quickly delivers the airflow to the air storage ring 25 through the air delivery pipe 1 24.

[0055] As the fan 23 continues to operate, the air pressure in the air storage ring 25 gradually increases. When the air pressure reaches the set storage threshold, the airlock set in the air storage ring 25 will automatically open. Subsequently, the stored high-pressure gas flows to the pressurizing ring 27 through the gas pipe 26. In the pressurizing ring 27, the gas is further guided to the air nozzle 28 and finally ejected from the air nozzle 28. This ejection process will generate a strong airflow to thoroughly clean the foreign matter and mucus attached to the surface of the detection head 3. In particular, for dirt with strong adhesion, the high pressure of the airflow can effectively peel off the attached matter.

[0056] Please refer to the attached Figure 6 A second motor 30 is disposed inside the fixed block 29, a scraper 31 is fixedly connected to the output end of the second motor 30, and a cleaning brush 33 is fixed to one side of the scraper 31;

[0057] A TOF sensor 32 is disposed at one end of the scraper 31 .

[0058] Specifically, during the unfolding process of the scraper 31, the cleaning brush 33 attached thereto will also be started synchronously to completely clean the foreign matter or mucus that may be attached to the surface of the detection head 3, ensuring that the lens and sensor of the detection head 3 are always in a clean state, thereby improving the detection accuracy. The role of the cleaning brush 33 is complementary to the laser adjustment process.

[0059] Working principle: when it is necessary to detect a tumor in a patient's body, we need to place the inner measuring tube 2 together with the detection head 3 in the patient's body. At this time, when the detection head 3 reaches the position corresponding to the existence of the tumor, the laser set in the detection head 3 will start to work. At this time, according to the built-in camera of the detection head 3, the environmental conditions of the tumor position are judged, and then the focal length of the device light source is adjusted. At this time, the driving motor 11 drives the shaft 12 to rotate, and the rotation of the shaft 12 will drive the gear 13 to rotate synchronously, and then through the meshing between the gear 13 and the gear 2 16, the shaft 2 15 drives the outer ring 17 to rotate, and the rotation of the outer ring 17 will adjust the position of the lens 18. When the lens 18 is adjusted to the appropriate lens 18, the motor 11 stops rotating, and the electric push rod 21 starts driving, thereby pushing the fixed plate 14, so that the fixed plate 14 is connected through the parts in contact with the fixed frame 10, so that the fixed frame 10 and the fixed plate 14 can be synchronously lowered, so that the determined lens 18 can be located at the center position to be lasered. The light source is irradiated, so that the light source is received by the TOF sensor 32 which is deployed by the scraper 31 driven by the motor 2 30 through reflection, and then the size of the tumor is determined. When the scraper 31 is deployed, the cleaning brush 33 provided therein can also clean the foreign matter or mucus attached to the surface of the detection head 3. Before adjusting the focal length, the drive of the motor 11 can also drive the gear 2 16 driven by it to rotate in conjunction with the gear 3 20. Because the gear ratios of the gear 2 16 and the gear 3 20 are set differently, the gear 3 The rotation speed of 20 will be much faster than that of gear two 16, thereby driving the rotating shaft three 22 to rotate. The rotating rotating shaft three 22 will drive the fan 23 to operate, and then supply gas to the air storage ring 25 through the air supply pipe one 24, thereby increasing the air pressure in the air storage ring 25. After storing a certain amount, the airlock at the position of the air storage ring 25 is released, and finally all the gas will be transported to the pressurizing ring 27 through the air supply pipe two 26, and finally ejected from the position of the air nozzle 28, thereby further cleaning the foreign matter and mucus attached to the surface of the detection head 3.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
