Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to a method, system, device and medium for detecting abnormal inner diameter of an endoscope channel. Background Art

[0002] According to the industry standard for medical endoscopes, for endoscopes with instrument channels, the minimum width of the channel should not be less than the nominal value. Therefore, during the production and quality inspection of endoscopes, it is necessary to perform abnormal detection on the inner diameter of the channel of the endoscope to avoid the minimum value of the inner diameter of the channel being less than the nominal value.

[0003] In the prior art, a guide wire is generally used to test the instrument channel of an endoscope. The specific testing process is as follows:

[0004] 1. Prepare a thin and soft guide wire (such as a steel wire with a diameter of 0.3 mm);

[0005] 2. Make sure the endoscope is closed and insert the guide wire into the instrument channel of the endoscope;

[0006] 3. Slowly push the guide wire into the instrument channel and observe whether there is any obstruction or resistance. If the guide wire can pass through the channel smoothly, it means that the patency is good. If an obstacle is encountered, gently try to pass through or around the obstacle, but do not apply too much force to avoid damaging the endoscope.

[0007] 4. During the operation, pay attention to whether the guide wire can pass through the instrument channel completely. If the guide wire is stuck or cannot pass through, further inspection or cleaning may be required.

[0008] The above method can only preliminarily test the patency of the endoscope instrument channel (i.e., it can only detect whether there are foreign objects in the instrument channel), but cannot detect whether the minimum value of the channel inner diameter is less than the nominal value, that is, it cannot truly realize the abnormal detection of the inner diameter of the endoscope instrument channel. Summary of the invention

[0009] In view of this, the present invention provides a method, system, device and medium for detecting abnormal inner diameter of an endoscope channel to solve the problem in the prior art that it can only preliminarily test the patency of the endoscope instrument channel but cannot detect whether the minimum value of the channel inner diameter is less than the nominal value.

[0056] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0057] Embodiment 1

[0058] This embodiment provides a method for detecting abnormal inner diameter of an endoscope channel. Figure 1 As shown, the method includes:

[0059] S1: providing a plurality of spheres with different preset diameters; wherein the preset diameter of each sphere satisfies a specified relationship with the nominal inner diameter of the instrument channel of the endoscope to be inspected;

[0060] S2: fixing the endoscope to be inspected at a first preset position so that the instrument channel of the endoscope to be inspected is located in a vertical direction;

[0061] S3: placing each ball into the instrument channel respectively, and obtaining the passing result of each ball in the instrument channel respectively;

[0062] S4: Determine the detection result of the inner diameter of the first channel of the endoscope to be inspected according to the passing results of all the balls.

[0063] In this embodiment, by providing a plurality of balls with preset diameters having a specified relationship with the nominal inner diameter of the endoscope to be inspected, it is convenient to directly use the balls to test the inner diameter of the instrument channel of the endoscope to be inspected, and the testing method is simple and easy to perform; the endoscope to be inspected is fixed at a first preset position, and its instrument channel is located in a vertical direction, which can facilitate the subsequent direct observation of the passage of the balls through the instrument channel; the inner diameter detection result of the first channel of the endoscope to be inspected is analyzed by the passage result of each ball through the instrument channel, so that it can be intuitively and accurately determined whether the inner diameter of the instrument channel meets the nominal value, and no complicated equipment or technology is required, nor a large number of professionals are required, and both the equipment cost and the detection cost are low.

[0064] Each step of the method for detecting abnormal inner diameter of an endoscope channel in this embodiment is described in detail below.

[0065] Specifically, in the present embodiment S1, assuming that the total number of balls is n, the specified relationship satisfied between the preset diameter and the nominal inner diameter of the i-th ball among the n balls is specifically:

[0066] ;

[0067] Among them, d i is the preset diameter of the i-th sphere, D is the nominal inner diameter of the instrument channel of the endoscope to be inspected, is the first preset threshold, i is a positive integer and satisfies i≤n.

[0068] In the above specified relationship, the preset diameter of the sphere can be greater than or equal to the nominal inner diameter of the endoscope to be inspected, or smaller than the nominal inner diameter. Regardless of whether it is greater than or smaller than the nominal inner diameter, the absolute value of the difference between it and the nominal inner diameter is less than the first preset threshold value. That is, the preset diameter of the sphere is not much different from the nominal inner diameter. Through the spheres with this specified relationship, it is convenient to analyze the difference between the actual inner diameter of the endoscope to be inspected and the nominal inner diameter through the passage of these spheres, and then judge whether the actual inner diameter of the endoscope to be inspected meets the requirements.

[0069] The nominal inner diameter of the instrument channel of the endoscope to be inspected is usually determined during manufacture, and the number of the balls and the first preset threshold value can be preset and adjusted according to actual conditions. For example, if the nominal inner diameter of the endoscope to be inspected is 1.5 mm, the preset diameters of the balls can be 1.45 mm, 1.46 mm, ..., 1.49 mm, 1.50 mm, 1.51 mm, etc.

[0070] Specifically, in the present embodiment S1, each spherical ball is a carbon steel ball or a tungsten steel ball.

[0071] The balls made of the above materials usually have a higher density, which helps to place the balls into the instrument channel by utilizing their own gravity to smoothly pass through the instrument channel, thereby avoiding factors such as the rough inner wall of the instrument channel causing the balls to be unable to pass through, which in turn leads to inaccurate abnormal detection results of the endoscope to be inspected, thereby ensuring the accuracy and reliability of the detection results and reducing errors.

[0072] In this embodiment S2, by fixing the endoscope to be inspected at the first preset position, on the one hand, its instrument channel is located in the vertical direction, which is convenient for subsequent analysis of the abnormal detection of the inner diameter of the channel of the endoscope to be inspected by the operation of the ball and the results of its passing; on the other hand, the influence of the movement of the endoscope to be inspected on the abnormal detection of the inner diameter of its channel is avoided, thereby improving the detection accuracy.

[0073] After S2 of this embodiment, the method further includes:

[0074] The laser alignment device is used to calibrate the instrument channel of the endoscope to be inspected in the vertical direction.

[0075] By calibrating the instrument channel in the vertical direction through the laser alignment device, it can be effectively ensured that the instrument channel is accurately located in the vertical direction, thereby ensuring the accuracy and reliability of subsequent detection of abnormalities in the inner diameter of the channel of the endoscope to be inspected.

[0076] Specifically, a laser is emitted from the first end (entrance or exit) of the instrument channel into the interior of the instrument channel by a laser alignment device, and the laser emitted from the second end (exit or entrance) is used for calibration. The calibration method of the laser alignment device is a conventional technology of the device, and the specific details are not repeated here.

[0077] After S2 and before S3 in this embodiment, the method further includes:

[0078] An air pump disposed at the inlet of the instrument channel or an air compression device disposed at the outlet of the instrument channel is used to input an air flow of a preset flow rate into the instrument channel.

[0079] By utilizing an air pump at the entrance of the instrument channel or an air compression device at the exit of the instrument channel to input an air flow of a preset flow rate into the instrument channel, a thin gas layer can be formed between the ball and the inner wall of the instrument channel. The gas layer can act as an "air cushion" to reduce direct contact between the surface of the ball and the inner wall of the instrument channel, reduce friction, and help the ball to pass through the instrument channel smoothly, thereby avoiding factors such as the rough inner wall of the instrument channel that may cause the ball to not pass through, which in turn may lead to inaccurate abnormal detection results of the endoscope to be inspected, further ensuring the accuracy and reliability of the detection results and reducing errors.

[0080] Among them, the air pump and the air compression device can both adopt devices of conventional structural design, and the specific structure is not limited here.

[0081] Preferably, if Figure 2 As shown, this embodiment S3 includes:

[0082] S31: placing each ball in sequence from the entrance of the instrument channel of the endoscope to be inspected in the order of the preset diameter from small to large, and obtaining the appearance of the corresponding ball at the exit of the instrument channel after each ball is placed in sequence;

[0083] S32: according to the appearance of the corresponding ball at the exit of the instrument channel after each ball is placed, the passing result of each ball in the instrument channel is obtained in sequence.

[0084] Putting the balls into the instrument channel in the order of preset diameter from small to large can ensure the orderly progress of the entire test process and improve the test efficiency. On the other hand, it is convenient to conduct subsequent analysis based on the appearance of the balls at the exit of the instrument channel to realize abnormal detection of the inner diameter of the channel of the endoscope to be inspected. The principle is simple and the results are effective. Subsequent analysis and abnormal detection can be performed without the need for professionals.

[0085] Furthermore, in the above S31, the appearance of the corresponding ball at the exit of the instrument channel after each ball is placed is obtained in sequence, including:

[0086] Using the image acquisition device disposed at the exit of the instrument channel, the image of the exit of the instrument channel after each ball is placed is acquired in sequence;

[0087] Image analysis is performed on each collected image to obtain the appearance of the corresponding ball at the exit of the instrument channel after each ball is placed.

[0088] Through the above method, the appearance of the ball can be obtained using simple devices and principles, which is convenient for subsequent analysis and anomaly detection. The whole process is intuitive and efficient, and the results are reliable and accurate.

[0089] Specifically, the image acquisition device can be a high-speed stroboscopic camera, which can effectively capture images at the exit of the instrument channel, and analyze whether a sphere appears in the image through image recognition technology, thereby obtaining the corresponding sphere appearance situation.

[0090] Furthermore, the above S32 includes:

[0091] S321: for the i-th ball, when the corresponding ball appearance at the exit of the instrument channel after the i-th ball is placed is specifically no ball, the passing result of the i-th ball in the instrument channel is failure;

[0092] S322: When the corresponding ball appearance at the exit of the instrument channel after the i-th ball is placed is specifically a ball appearance, the passing result of the i-th ball in the instrument channel is passing;

[0093] S323: According to the same method, the passing result of each ball in the instrument channel is obtained in turn.

[0094] The corresponding passing result can be obtained directly based on the appearance of each ball in the instrument channel. It does not require complicated equipment and technology, and can effectively improve the detection efficiency and cost of the entire process.

[0095] This embodiment S4 includes:

[0096] S41: among all the balls, when the passing result of the i-th ball in the instrument channel is passed and the passing result of the i+1-th ball in the instrument channel is failed, determining whether the i-th ball is the target ball of the instrument channel;

[0097] S42: When the i-th ball is the target ball of the instrument channel, it is determined that the first channel inner diameter detection result of the endoscope to be inspected is that the channel inner diameter meets the nominal value; when the i-th ball is not the target ball of the instrument channel, it is determined that the first channel inner diameter detection result of the endoscope to be inspected is that the channel inner diameter does not meet the nominal value.

[0098] When the result of the i-th ball passing is passed and the result of the i+1-th ball passing is not passed, it means that the inner diameter of the channel of the endoscope to be inspected is just larger than the i-th ball and smaller than the i+1-th ball; therefore, the first inner diameter detection result of the endoscope to be inspected is determined by further judging whether the i-th ball is the target ball. When it is the target ball (referring to a ball with a preset diameter that is exactly the same as the nominal inner diameter of the endoscope to be inspected), it means that the actual inner diameter of the endoscope to be inspected meets the nominal value, otherwise it means that the actual inner diameter of the endoscope to be inspected does not meet the nominal value. Through the above analysis method, the abnormal inner diameter of the channel of the endoscope to be inspected can be detected intuitively and accurately based on the passing result of the ball, ensuring that it meets the production and quality inspection requirements.

[0099] Specifically, in the above S41, judging whether the i-th ball is the target ball of the instrument channel includes:

[0100] S411: Determine whether the preset diameter of the i-th sphere is less than or equal to the nominal inner diameter;

[0101] S412A: When the preset diameter of the i-th sphere is less than or equal to the nominal inner diameter, calculate whether the difference between the nominal inner diameter and the preset diameter of the i-th sphere is less than or equal to a second preset threshold value, and if so, determine that the i-th sphere is the target sphere; otherwise, determine that the i-th sphere is not the target sphere; wherein the second preset threshold value is less than the first preset threshold value;

[0102] S412B: When the preset diameter of the i-th sphere is greater than the nominal inner diameter, it is directly determined that the i-th sphere is not the target sphere.

[0103] When the preset diameter of the ith sphere is less than or equal to the nominal inner diameter, and the difference between the nominal inner diameter and the preset diameter is less than or equal to the second preset threshold value, it means that the actual inner diameter of the instrument channel is just greater than or equal to the preset diameter of the sphere, and the difference from the preset diameter is not large. It can be regarded that the actual inner diameter of the instrument channel is close to the preset diameter of the ith sphere and can just allow it to pass through. Then the ith sphere is the target sphere, and the actual inner diameter of the instrument channel meets the nominal value; otherwise, the actual inner diameter of the instrument channel is greater than or equal to the preset diameter of the ith sphere, and the difference from the preset diameter is large. It cannot be regarded as the target sphere, which means that although the actual inner diameter of the instrument channel allows the ith sphere to pass through, it differs too much from the nominal value and does not meet the requirements. When the preset diameter of the ith sphere is greater than the nominal diameter, it also means that although the actual inner diameter of the instrument channel allows the ith sphere to pass through, it differs too much from the nominal value and does not meet the requirements.

[0104] Through the above judgment process, this embodiment can accurately and efficiently judge whether the inner diameter of the channel of the endoscope to be inspected meets the nominal value requirements. The principle is simple and easy to implement.

[0105] The second preset threshold is smaller than the first preset threshold, and the second preset threshold can be specifically set according to the size of the first preset threshold, which is not limited here.

[0106] Preferably, if Figure 3 As shown, in S4, after determining that the first channel inner diameter detection result of the endoscope to be inspected is specifically that the channel inner diameter meets the nominal value, the method further includes:

[0107] S5: fixing the endoscope to be inspected at a second preset position so that the instrument channel of the endoscope to be inspected is located in a horizontal direction;

[0108] S6: Using a dynamometer, the target ball is pulled from the first end to the second end of the instrument channel, and the dynamometer is used to obtain the traction data corresponding to the dynamometer in real time during the pulling process;

[0109] S7: Determine the detection result of the inner diameter of the second channel of the endoscope to be inspected according to the tension data acquired in real time.

[0110] In addition to the instrument channel, the insertion tube of the endoscope is generally equipped with cables, traction ropes, capillaries and other parts. Therefore, when the inner diameter of the instrument channel of the endoscope is large, it will occupy the use space of other parts in the insertion tube of the endoscope. Therefore, it is hoped that the instrument channel has a better inner diameter uniformity. After determining that the inner diameter of the channel of the endoscope to be inspected meets the nominal value, the endoscope to be inspected is re-tested through the above steps to determine the second channel inner diameter test result. On the basis of whether the inner diameter of the test channel meets the nominal value, the ball can be further used to judge whether the inner wall of the entire instrument channel of the endoscope to be inspected meets the uniformity, thereby further ensuring the quality of the endoscope to be inspected.

[0111] Specifically, in the above S5, similar to fixing the endoscope to be inspected at the first preset position, by fixing the endoscope to be inspected at the second preset position, on the one hand, its instrument channel is located in the horizontal direction, which is convenient for subsequent acquisition of the tension data of the tension meter when the ball moves horizontally, and the tension data is used to further analyze the abnormal detection of the inner diameter of the channel of the endoscope to be inspected; on the other hand, the influence of the movement of the endoscope to be inspected on the abnormal detection of the inner diameter of its channel is avoided, thereby improving the detection accuracy.

[0112] Similar to aligning the instrument channel in the vertical direction, the laser alignment device can also be used to calibrate the instrument channel in the horizontal direction. The principle and operation method are similar to the aforementioned calibration in the vertical direction, and will not be repeated here.

[0113] Specifically, in the above S6, since the preset diameter of the target sphere is closest to the actual inner diameter of the endoscope to be inspected, by directly using the dynamometer to pull the target sphere, on the one hand, it can ensure that the target sphere can pass through the instrument channel smoothly and horizontally, and on the other hand, the tension data can be collected in real time during its horizontal passage, which is convenient for subsequent analysis and abnormality detection based on the tension data.

[0114] The dynamometer may be a conventional dynamometer, and there is no limitation thereto.

[0115] Specifically, the above S7 includes:

[0116] S71: Determine whether there is an abnormal fluctuation value in the tension data obtained in real time;

[0117] S72: When there is no abnormal fluctuation value in the tension data acquired in real time, determine that the second channel inner diameter detection result of the endoscope to be inspected is specifically that the channel inner diameter is uniform; otherwise, determine that the second channel inner diameter detection result of the endoscope to be inspected is specifically that the channel inner diameter is non-uniform.

[0118] In an actual endoscope, if the inner diameter of the instrument channel is uniform, the tension of the target ball is uniform during its horizontal passage through the instrument channel. If the tension data shows abnormal fluctuations, it means that there is a foreign body in the instrument channel or the local inner diameter is uneven, which can be regarded as uneven channel inner diameter. For example, when there is a larger inner diameter in the middle section of the instrument channel, the tension data there will be abnormally reduced compared to other positions. This embodiment can effectively determine the second channel inner diameter detection result of the endoscope to be inspected, that is, whether the channel inner diameter is uniform, directly by whether there is an abnormal fluctuation value in the tension data. It also does not require complex equipment and principles, is simple to operate, easy to execute, and does not require a large number of professionals. The equipment cost and detection cost are both low.

[0119] Specifically, in S71 of this embodiment, the tension data within a preset time can be obtained, and then the data can be standardized to convert the tension data into the same dimension for easy comparison and analysis. Then, according to industry experience, upper and lower thresholds are set. If there is data outside the range defined by the upper and lower thresholds in the standardized tension data, it is determined that there is an abnormal fluctuation value, otherwise it is determined that there is no abnormal fluctuation value.

[0120] Embodiment 2

[0121] A system for detecting abnormal inner diameter of an endoscope channel is applied to the method for detecting abnormal inner diameter of an endoscope channel in the first embodiment, such as Figure 4 As shown, the system comprises:

[0122] The first detection module is used to provide a plurality of balls with different preset diameters; wherein the preset diameter of each ball satisfies a specified relationship with the nominal inner diameter of the instrument channel of the endoscope to be inspected; and is also used to fix the endoscope to be inspected at a first preset position so that the instrument channel of the endoscope to be inspected is located in a vertical direction; and each ball is placed in the instrument channel respectively, and the passing result of each ball in the instrument channel is obtained respectively;

[0123] The first analysis module is used to determine the detection result of the inner diameter of the first channel of the endoscope to be inspected according to the passing results of all the balls.

[0124] In this embodiment, a plurality of balls having preset diameters having a specified relationship with the nominal inner diameter of the instrument channel of the endoscope to be inspected are provided through the first detection module, so that the balls can be directly used to test the inner diameter of the channel of the endoscope to be inspected. The testing method is simple and easy to perform. The endoscope to be inspected is fixed at a first preset position, and its instrument channel is located in a vertical direction, so that the passage of the balls through the instrument channel can be directly observed. The first analysis module is used to analyze the inner diameter detection result of the first channel of the endoscope to be inspected based on the passage result of each ball through the instrument channel. It can intuitively and accurately determine whether the inner diameter of the instrument channel meets the nominal value.
