Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a novel endoscope positioning device for digestive tract lesions. Background Art

[0002] Digestive tract diseases are common diseases that have a significant impact on human health. Endoscopy, as an important means of diagnosing digestive tract lesions, can visually observe the internal conditions of the digestive tract and provide a key basis for accurate diagnosis of diseases. However, during the current endoscopic examination, there are many problems with the release of the endoscope.

[0003] At present, the release of endoscopes mainly relies on manual operation. This method has obvious disadvantages in practical applications. On the one hand, it is difficult to accurately control the length of endoscope release by manual operation. Due to differences in operating habits and experience of different doctors, it is easy for the endoscope to be released too long or too short during the examination. If the endoscope is released too long, it may cause unnecessary stimulation and damage to the patient's digestive tract, increase the patient's pain, and may also cause inaccurate examination sites and affect the accuracy of the examination results; if the endoscope is released too short, it will not be able to reach the target inspection area, resulting in incomplete examination, missing lesions, and delaying diagnosis and treatment of the disease. On the other hand, the efficiency of manual operation is relatively low, and it is difficult to meet the needs of rapid examination. When facing a large number of patients, the manual operation of endoscope release not only consumes the doctor's energy, but also prolongs the examination time of a single patient and reduces the overall medical efficiency.

[0004] In addition, after endoscopic examination, the cleaning of the endoscope channel cannot be ignored. Since the endoscope comes into contact with various body fluids, tissues and impurities in the digestive tract, if the cleaning is not thorough, the impurities will adhere to the surface of the endoscope channel, which will not only affect the clarity of the next examination, but also breed bacteria, causing cross infection and posing a threat to the health of subsequent patients. Traditional cleaning methods are often not convenient and efficient enough to meet the needs of rapid clinical turnover.

[0005] In summary, the existing endoscopic examination methods have shortcomings in operation accuracy, examination efficiency and endoscope cleaning. There is an urgent need for a new endoscopic positioning device for gastrointestinal lesions to improve the accuracy, efficiency and safety of endoscopic examinations. Summary of the invention

[0006] In order to overcome the existing problems, the embodiment of the present application provides a novel gastrointestinal lesion endoscope positioning device, in which a micro motor is arranged on the surface wall of the frame, the micro motor is located inside the frame and connected to the driving wheel, and a driven wheel is arranged on one side of the driving wheel. This design constructs a power transmission system. When the endoscope tube needs to be transported, the endoscope tube is put in from the feed hole, the micro motor is started, and the micro motor drives the driving wheel to rotate. The driving wheel cooperates with the driven wheel during the rotation process, thereby realizing the transmission of the endoscope tube. Compared with the traditional manual operation, this mechanical transmission method has higher accuracy and stability.

[0007] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0010] Preferably, a feed hole is provided on one side of the frame, and the feed hole is opened on one side of the frame, and its shape is circular or elliptical, and its size is slightly larger than the outer diameter of the endoscope tube, so that the endoscope tube can be smoothly inserted, and the edge of the feed hole is rounded to prevent the tube surface from being scratched when the endoscope tube is inserted, and a cleaning cylinder is provided on the side of the frame away from the feed hole, and the cleaning cylinder and the frame are detachable structures, and there is a rotating brush inside the cleaning cylinder, and the feed hole is the same size as the cleaning cylinder.

[0011] Preferably, a displacement sensor is provided inside the frame at one side of the driven wheel. The displacement sensor is installed at a position inside the frame close to the cleaning tube, and its detection end is aligned with the endoscope tube. The displacement sensor adopts a high-precision photoelectric sensor or a Hall sensor, which can monitor the movement distance of the endoscope tube in real time and transmit the detected signal to the control system. The installation position of the displacement sensor is close to one side of the cleaning tube. The cleaning tube is located at one end of the frame and adopts a cylindrical structure. The material is acid- and alkali-resistant, easy-to-clean plastic or metal. A rotating brush is provided inside the cleaning tube. When the endoscope tube passes through the cleaning tube, the rotating brush can brush the surface of the tube to remove impurities. One end of the cleaning tube is fixedly connected to the frame, and a detachable end cover can be provided at the other end to facilitate cleaning and maintenance of the inside of the cleaning tube.

[0012] Preferably, an adjusting column is provided at one end of the frame, and the adjusting column is installed on one side of the frame, one end of which is connected to the frame through a bearing, and the other end is connected to the driven wheel. The adjusting column is in the form of a threaded rod with a thread on the surface. When the adjusting column is rotated, due to the action of the thread, the driven wheel will move inside the frame along the axial direction of the adjusting column. The connection between the adjusting column and the driven wheel is a rotatable structure. The adjusting column is screwed to the inside of the frame, and one end of it is connected to the driven wheel.

[0013] Preferably, the limit groove matches the moving trajectory of the driven wheel, the size of the limit groove is the same as the size of the limit rod, the limit groove is arranged inside the frame, and matches the moving trajectory of the driven wheel. The limit groove is shaped as a rectangular groove, and its length and width are designed according to the size and moving range of the driven wheel, which can not only ensure that the limit rod can slide freely in the groove, but also effectively limit the moving direction of the driven wheel to prevent it from deviation.

Compared with traditional manual operation, this mechanical transmission method has higher accuracy and stability.

[0017] 2. The displacement sensor can detect the delivery volume of the endoscope pipeline in real time. By accurately monitoring the delivery volume, it can achieve accurate transmission and positioning of the endoscope pipeline. This avoids the problem of too long or too short release of the endoscope due to manual operation, ensuring that the endoscope can accurately reach the target inspection area, improving the accuracy and efficiency of the inspection, and reducing unnecessary impact on patients.

[0018] 3. A cleaning cylinder is set at one end of the frame, and its function is to clean the recovered endoscope tube. After each inspection, the endoscope tube passes through the cleaning cylinder, which can effectively remove impurities attached to the surface of the endoscope tube to avoid contamination of the endoscope by residual impurities, thereby ensuring the cleanliness of the endoscope, reducing the risk of cross infection, and providing reliable conditions for subsequent inspections.

[0019] 4. An adjusting column is arranged on one side of the frame, and the adjusting column is connected to the driven wheel. When the adjusting column rotates, it can drive the driven wheel to move inside the frame.

[0029] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0030] Example

[0031] This embodiment provides a specific structure of a novel endoscope positioning device for digestive tract lesions. Figure 1-4 As shown, the frame 1 includes a main support structure of the entire device, which is made of high-strength, corrosion-resistant metal materials such as stainless steel, and is used to accommodate and install other components. The size of the frame 1 is designed according to actual use requirements and the layout of the endoscope inspection equipment, so as to ensure that each component can be reasonably installed and easy to operate and maintain. A micro motor 2 is installed on the upper surface wall of the frame 1, which is connected to a power source and controlled by a control switch. The micro motor 2 is located inside the frame 1 and is provided with a driving wheel 7. A driven wheel 8 is provided inside the frame 1 and is located on one side of the driving wheel 7.

[0032] Among them, a limit groove 4 is provided on the upper surface wall of the frame 1 on one side of the driven wheel 8, and a limit rod 10 is slidably connected inside the limit groove 4. The limit rod 10 is connected to the driven wheel 8. The micro motor 2 runs to drive the driving wheel 7 to rotate, and cooperates with the driven wheel 8 to drive the endoscope tube to move. The driving wheel 7 and the driven wheel 8 have the same size, and the outer walls of the driving wheel 7 and the driven wheel 8 are both covered with anti-slip sleeves.

[0033] A feeding hole 3 is provided on one side of the frame 1. The feeding hole 3 is opened on one side of the frame 1 and is circular or elliptical in shape. The size is slightly larger than the outer diameter of the endoscope tube so that the endoscope tube can be smoothly inserted. The edge of the feeding hole 3 is rounded to prevent the tube surface from being scratched when the endoscope tube is inserted. A cleaning barrel 5 is provided on the side of the frame 1 away from the feeding hole 3. The cleaning barrel 5 and the frame 1 are detachable structures. There is a rotating brush inside the cleaning barrel 5. The feeding hole 3 and the cleaning barrel 5 are the same size.

[0034] A displacement sensor 9 is provided inside the frame 1 at one side of the driven wheel 8. The displacement sensor 9 is installed at a position inside the frame 1 close to the cleaning tube 5, and its detection end is aligned with the endoscope pipe. The displacement sensor 11 adopts a high-precision photoelectric sensor or a Hall sensor, which can monitor the moving distance of the endoscope pipe in real time and transmit the detected signal to the control system. The installation position of the displacement sensor 9 is close to one side of the cleaning tube 5. The cleaning tube 5 is located at one end of the frame 1 and adopts a cylindrical structure. The material is acid- and alkali-resistant, easy-to-clean plastic or metal. A rotating brush is provided inside the cleaning tube 5. When the endoscope pipe passes through the cleaning tube 5, the rotating brush can brush the surface of the pipe to remove impurities. One end of the cleaning tube 5 is fixedly connected to the frame 1, and a detachable end cover can be provided at the other end to facilitate cleaning and maintenance of the inside of the cleaning tube 5.

[0035] An adjusting column 6 is provided at one end of the frame 1. The adjusting column 6 is installed on one side of the frame 1. One end of the adjusting column 6 is connected to the frame 1 through a bearing, and the other end is connected to the driven wheel 8. The adjusting column 6 is in the form of a threaded rod with a thread on the surface. When the adjusting column 6 is rotated, due to the action of the thread, the driven wheel 8 will move inside the frame 1 along the axial direction of the adjusting column 6. The connection between the adjusting column 6 and the driven wheel 8 is a rotatable structure. The adjusting column 6 is screwed inside the frame 1, and one end of the adjusting column 6 is connected to the driven wheel 8.

[0036] The limit groove 4 matches the moving trajectory of the driven wheel 8. The size of the limit groove 4 is the same as the size of the limit rod 10. The limit groove 4 is arranged inside the frame 1 to match the moving trajectory of the driven wheel 8. The shape of the limit groove 4 is a rectangular groove. Its length and width are designed according to the size and moving range of the driven wheel 8. It can not only ensure that the limit rod 10 can slide freely in the groove, but also effectively limit the moving direction of the driven wheel 8 to prevent it from deviation.

[0037] The micro motor 2 and the frame 1 are detachably installed. A transmission shaft 11 is provided at the output end of the micro motor 2. The transmission shaft 11 connects the output shaft of the micro motor 2 and the driving wheel 7. A high-strength metal shaft is used, and both ends are respectively connected to the output shaft of the micro motor 2 and the driving wheel 7 by keys or interference fits. The micro motor 2 is fixedly installed on the surface wall of the frame 1 and is fastened by screws or snaps to ensure that it will not loosen during operation. The power of the micro motor 2 is selected according to the power required for the transmission of the endoscope pipeline, which can not only ensure sufficient power to drive the driving wheel 7 to rotate, but also consider energy saving and the overall stability of the device.

[0038] By adopting the above technical solution:

[0039] The medical staff first adjusts the position of the driven wheel 8 according to the size of the gastroscope tube by rotating the adjustment column 6. The rotation of the adjustment column 6 drives the driven wheel 8 to move in the frame 1, ensuring that the distance between the driving wheel 7 and the driven wheel 8 is adapted to the outer diameter of the gastroscope tube.

[0040] After confirming that the equipment has been adjusted, the medical staff inserts the gastroscope tube from the feed hole 3 so that it is located between the driving wheel 7 and the driven wheel 8, and then turns on the control switch of the micromotor 2. The micromotor 2 starts and drives the driving wheel 7 to rotate. The driving wheel 7 and the driven wheel 8 cooperate with each other to smoothly transmit the gastroscope tube toward the patient's oral cavity. During the transmission process, the displacement sensor 9 monitors the delivery volume of the gastroscope tube in real time and feeds back the signal to the control system. When the gastroscope tube reaches the predetermined entry length, the control system automatically stops the micromotor 2, thereby achieving precise positioning of the gastroscope.

[0041] Working principle:

[0042] Before performing an endoscopic inspection, rotate the adjusting column 6 according to the size of the endoscope tube to be used, and drive the driven wheel 8 to move inside the frame 1 through the adjusting column 6, so that the distance between the driving wheel 7 and the driven wheel 8 matches the diameter of the endoscope tube. At the same time, check whether the cleaning device inside the cleaning tube 5 is working normally, such as checking whether the brush is damaged.

[0043] The endoscope tube is slowly put in from the feeding hole 3, ensuring that the endoscope tube is located between the driving wheel 7 and the driven wheel 8 and is in full contact with both. The control switch of the micro motor 2 is turned on, the micro motor 2 is started, and the driving wheel 7 is driven to rotate. During the rotation of the driving wheel 7, the endoscope tube is transmitted to the target direction by cooperating with the driven wheel 8. During the transmission process, the displacement sensor 11 monitors the conveying amount of the endoscope tube in real time and feeds back the signal to the control system. The control system accurately controls the operation of the micro motor 2 according to the preset conveying length. When the preset conveying length is reached, the micro motor 2 is automatically stopped to achieve accurate positioning of the endoscope tube.

[0044] When the endoscope tube reaches the target inspection area, the doctor can perform the endoscope inspection operation. After the inspection is completed, the micro motor 2 is reversely started to recycle the endoscope tube into the frame 1. During the recycling process, the endoscope tube passes through the cleaning tube 5, and the cleaning device in the cleaning tube 5 cleans the surface of the endoscope tube to remove the attached impurities.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
