Abstract
Description
Technical Field
[0001] The utility model relates to an illumination detection device for a medical endoscope system, in particular to an illumination detection device for a medical endoscope system which can match various components in the endoscope system. Background Art
[0002] A surgical medical endoscope system includes an endoscope host, a light source, an optical fiber, a camera, and an endoscope body. The endoscope body is the doctor's "eye," entering the body through natural channels or surface perforations to directly observe the body's organs or tissues, and performing minimally invasive surgery when necessary to diagnose or treat diseases. The quality of the endoscope system's lighting performance will directly affect the doctor's observation and the outcome of the surgical procedure. The lighting light is generated by the light source and reaches the endoscope through an optical fiber catheter, and then reaches the body through the optical fiber inside the endoscope. Luminous flux is a physical quantity that measures the light source's luminous ability. Illuminance reflects the luminous flux per unit area. The formula reflecting the relationship between the two is: E = Φv / A, where E is illuminance, Φv is luminous flux, and A is area. Luminous flux reflects the radiant energy of the light source that can be perceived by the human eye, which has a significant impact on the effectiveness of the endoscope. Too low illumination will make it impossible to observe the state of the body's organs or tissues.
[0003] Endoscope system equipment that may affect illumination includes light source devices, fiber optic catheters and endoscope bodies. The cold light source provides a stable, high-intensity, cooled light source for endoscopic examinations and surgeries. The optical fiber is used to transmit the light source to the endoscope body. There is an optical fiber inside the body, and the light source is illuminated to the required cavity through the optical fiber. For cold light sources (xenon lamps or LED lamp groups), the luminous flux will decay with the increase of usage time, and will be damaged when it decays to a certain extent. Therefore, regular testing is required. The endoscope body and fiber optic catheter are also valuable and fragile items. After long-term use, bumps, cleaning, disinfection, etc., the internal optical fiber will cause irreversible damage.
[0004] The lighting performance of an endoscope system directly impacts the doctor's observations and surgical outcomes. If, during minimally invasive surgery, the endoscope is inserted into the human body only to be found to be unusable due to dim lighting, this significantly increases the risk of treatment and may even lead to surgical failure. If the cause of the problem is later traced back to the endoscope's optical fiber or light source, multiple investigations are required to determine the specific device before the problem can be repaired. This process wastes considerable time, significantly increases workload, impacts the surgical process, and reduces the quality of medical care.
[0005] However, the current state of the art is that there is no complete set of devices specifically designed to test the illumination of medical endoscopes. Most of the available devices can measure illumination and color rendering index. The main problem is that the interfaces are inconsistent, making it impossible to couple and connect them for testing. There is also no relevant inspection method. Utility Model Content

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments. Those skilled in the art should know that the following specific embodiments or specific implementation methods are a series of optimized settings listed by the present invention to further explain the specific content of the utility model, and these settings can be combined with each other or used in association with each other, unless it is clearly stated in the present invention that some or a specific embodiment or implementation method cannot be associated with other embodiments or implementation methods or used together. At the same time, based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0027] Reference Figure 1-7 As shown, the medical endoscope system illumination detection device provided by Example 1 of the present invention includes a light detector and can also be configured with a light source device 1. The light source device 1 has a light source output plug-in terminal 2, and the light detector has a detection head 3. The detection head 3 is connected to the host 4 of the light detector through a wire. A detection support component is fixed on the detection head 3, and the detection support component includes a lower mounting frame and an upper cover body 5. The upper end of the cover body 5 is provided with a plug connector 6. The lower part of the cover body 5 is opened to cover the position of the detection eye 7 of the detection head 3. The cover body 5 can enclose the detection eye 7, so that the environment for measuring illumination is enclosed to avoid interference. Moreover, since the detection environment is always consistent, it will not be affected by the ambient light intensity, etc., which can improve the detection accuracy and efficiency, and can prevent the detection head 3 from being damaged by bumps. The plug connector 6 has an insertion port 8, and the upper end of the plug connector 6 has an external thread. The plug connector 6 is equipped with a threaded connection cover 9 with an internal thread. The threaded connection cover 9 has a socket 10 in the center, and the socket 10 has an elastic annular edge 18. The elastic annular edge 18 is usually made of highly elastic rubber. The output end of the light source passes through the socket 10, and the threaded connection cover 9 is sleeved on the plug connector 6 and threadedly connected. The output end of the light source enters the inside of the cover body 5 and faces the detection head 3. The threaded connection between the threaded connection cover 9 and the plug connector 6 can make the output end of the light source to be detected more stably and firmly aligned with the detection eye 7 of the detection head 3, reduce shaking, and reduce the impact of changes in detection posture and position, maintain the uniformity of the front and back data standards, and improve accuracy and efficiency.
[0028] Reference Figure 7-9As shown, in Example 1, the light source output plug-in terminal 2, the endoscope output terminal and the optical fiber catheter output terminal of the light source device are respectively equipped with threaded connection covers 9, and the diameter of the socket 10 of each threaded connection cover 9 matches the light source output plug-in terminal 2, the endoscope output terminal and the optical fiber catheter output terminal of the light source device 1, respectively, and the elastic annular edge 18 is tightened on the outer wall of the end. The threaded connection cover 9 includes a first connection cover corresponding to the long metal catheter 11a of the endoscope 11, a second connection cover corresponding to the external end of the optical fiber catheter 12, and a third connection cover corresponding to the standard light guide connector 13 plugged into the light source output plug-in terminal 2 of the light source device 1, wherein the external end of the optical fiber catheter 12 also needs to be connected to the standard light guide connector 13 before being inserted into the connector 6 of the detection head 3 for illumination detection. The standard light guide connector 13 includes light source connectors from mainstream manufacturers STORZ, Stryker, and Wolf, wherein the optical fiber The catheter 12 and the light source device 1 usually lack an optical fiber bundle at the output end, so they cannot transmit output light for detection. Therefore, a standard light guide connector 13 needs to be configured for detection. During detection, the external end of the optical fiber catheter is connected to the standard light guide connector 13. The standard light guide connector 13 is inserted into the insertion port 8 of the detection head 3 after being sleeved with the second connecting cover. The end of the long metal catheter 11a of the endoscope 11 has an optical fiber to transmit output light, so there is no need to configure an additional connector for light guidance. The difference between the first connecting cover, the second connecting cover, and the third connecting cover is only that they match different jack diameters.
[0029] Reference Figure 7 As shown, in order to more flexibly, conveniently, and securely install the detection support assembly, the mounting frame includes multiple highly elastic sleeve straps 14 at the bottom, typically two highly elastic sleeve straps 14, which are placed around the housing of the detection head 3 and tightened. This installation method is more convenient and flexible. By separately configuring the first connection cover, the second connection cover, and the third connection cover, the output terminals of different devices to be tested can be adapted, improving convenience and efficiency.
[0030] Reference Figure 7-9As shown, the medical endoscope system illumination detection device provided by the present invention can be completely delivered to the hospital disinfection supply center, or directly placed in the cleaning room of the operating room. After the operation is completed, the optical fiber and the optical fiber inside the endoscope can be detected after the endoscope is washed and dried, and the detection results are entered into the system. For the endoscope system in a critical state, timely tracking is achieved. The method is as follows: first, insert the standard light guide connector 13 into the light source output plug-in terminal 3 of the light source device 1, and before insertion, connect the threaded connection cover 9 to the standard light guide connector 13 with the jack, and at the same time, thread the threaded connection cover 9 and the plug-in connector 6, and at the same time, insert the standard light guide connector 13 into Insert it into the port 8 and align it with the detection head 3, start the light detector and the light source device 1 to obtain the illumination data of the light source device; secondly, connect the threaded connection cover 9 to the output end of the optical fiber catheter 12 in the same way as above. It is usually necessary to connect the standard light guide connector 13 to the output end of the optical fiber catheter 12, and then thread it onto the plug connector 6. The input end of the optical fiber catheter 12 is inserted into the light source device through the standard light guide connector 13, and start the light detector and the light source device 1 to obtain illumination data; finally, connect the endoscope 11 to the optical fiber catheter 12 in the above manner, and connect the optical fiber catheter 12 to the light source device 1, and start the light detector and the light source device 1 to obtain illumination data. The illumination data of the above three types of equipment must be measured and recorded when the equipment is purchased. The maximum loss value of each device must be determined through communication with the manufacturer and verification of use. As long as the loss value of the device exceeds the preset maximum loss value, it can be replaced or repaired. By sequentially detecting the above three groups of equipment, it can be determined which specific device is lower than its maximum loss value. The preset maximum loss value of the light source device is the illumination data itself, while the fiber optic catheter and endoscope obtain the loss rate by calculating the ratio of the output end to the input end value. For example, light source device 1 is the simplest and can obtain the illumination value by direct detection. For another example, the fiber optic catheter 12 can be obtained by obtaining the illumination value (input end value) of light source device 1 and then detecting the illumination value after the fiber optic catheter 12 is installed. The illumination value at the output end of the fiber optic catheter is divided by the illumination value of the light source device to obtain the loss rate. When the loss rate of the fiber optic catheter 12 exceeds the preset maximum loss rate, it can be replaced. For another example, endoscope 11 is connected to the fiber optic catheter 12 and the light source device 1 to obtain the illumination value, and then divided by the illumination value detected at the output end of the fiber optic catheter 12 to obtain the loss rate. This allows for the establishment of systematic testing standards and testing methods.
[0031] Reference Figure 8-9As shown, Example 2 of the present invention is basically the same as Example 1, and the only difference is that the following mounting frame adopts a snap-on structure, specifically: the mounting frame includes a snap-on groove 19 provided on the detection head housing and a snap-on pin 15 fixed to the bottom of the cover body 5, the snap-on pin 15 has a snap-on block 16 at the lower end, and the snap-on block 16 has a downward inclined surface, and the side of the detection head housing is aligned with the snap-on groove 19 and has a snap-on groove 17 matching the snap-on block, and the snap-on groove 17 is open to the outside, and after the snap-on pin 15 is inserted into the snap-on groove 19, the snap-on block 16 is hooked at the snap-on groove 17, and this installation method has a more solid structure.

Therefore, any modifications or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention.
