[0002] Medical rigid endoscopes are now widely used in all departments of medical institutions. They are mainly used for the diagnosis and / or treatment of lesions in the superficial and shallow natural cavities of the human body and in the oral cavity through puncture.

[0003] Chinese patent publication (patent number: CN211478107U) discloses a medical endoscope lens inspection instrument, mainly composed of a rigid endoscope inspection tube, a camera, and a display. The rigid endoscope inspection tube includes an inspection tube body, a mounting piston, and an inspection magnifying glass. Using this inspection instrument, the internal structure of rigid endoscopes can be easily inspected. It is compatible with all DIN standard endoscope eyepieces. In addition, the display has an SD memory card unit, which facilitates the recording of quality management information throughout the entire "lifecycle" of the product, from purchase to disposal.

[0004] However, this invention can only test a single lens during the testing process, which reduces work efficiency. It also only supports optical imaging testing and cannot simulate different light source environments to detect coating damage or material discoloration. Therefore, a lens testing device for medical endoscopes is proposed. Summary of the Invention

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] Please see Figures 1-5 This utility model provides a technical solution: a lens detection device for medical endoscopes, including a base plate 101, a base 103 mounted on the top of the base plate 101, a transparent detection tube 104 mounted on one side of the base 103, a detection opening 105 on the transparent detection tube 104, a funnel 122 connected to the end of the transparent detection tube 104 away from the base 103, three support plates 106 mounted on one side of the base 103, and an LED adjustment device mounted on one side of the support plate 106. Color lamp 107, three support plates 106 are located on both sides and bottom of transparent detection tube 104 respectively, baffle bracket 109 is installed on the top of base 103, spring 110 is installed on the inner top wall of baffle bracket 109, baffle 108 is installed at the bottom of spring 110, rod 111 is installed on the top of baffle 108, rod 111 passes through the top of baffle bracket 109, handle 112 is fixedly connected to the top of rod 111, and spring 110 is wrapped around the outside of rod 111.

[0026] In this embodiment, specifically: a detection tube bracket 102 is installed at the bottom of the transparent detection tube 104, and the bottom of the detection tube bracket 102 is fixedly connected to the top of the base plate 101. The detection tube bracket 102 is used to support the transparent detection tube 104.

[0027] In this embodiment, specifically: a feeding tube 119 is installed on the base 103, the top of the feeding tube 119 is connected to the bottom of the transparent detection tube 104, a housing 120 is installed on the bottom of the base plate 101, and a drawer 121 is slidably connected to the inner side wall of the housing 120 via a track. A baffle bracket 109 passes through the top wall of the base plate 101 and the housing 120 in sequence. The above arrangement ensures that the lens after the test is completed enters the drawer 121.

[0028] In this embodiment, specifically: a weighing device 116 is installed on the top of the base plate 101. The weighing area of ​​the weighing device 116 is larger than the horizontal projected area of ​​the drawer 121. The weight of the lens is measured by the weighing device 116.

[0029] In this embodiment, specifically: a display 117 is mounted on the top of the base plate 101, and the display 117 is equipped with control buttons.

[0030] In this embodiment, specifically: four table legs 118 are installed at the bottom of the base plate 101. The multiple table legs 118 provide support for the base plate 101, thereby ensuring the stability of the operation of each mechanism on the base plate 101.

[0031] In this embodiment, specifically: a detector bracket 113 is installed on the top of the base plate 101, and a lens detector 114 is installed on the inner top wall of the detector bracket 113. The tilt angle of the lens detector 114 is the same as the tilt angle of the transparent detection tube 104. The detector bracket 113 is used to support the lens detector 114.

[0032] In this embodiment, specifically: a battery box 115 is installed on the top of the base plate 101, and a battery is installed inside the battery box 115. The battery is electrically connected to the LED color-changing lamp 107, the display 117 and the lens detector 114 respectively.

[0033] Working principle: The diameter of the lower opening of the funnel 122 is smaller than the length of the cylindrical lens to be inspected, ensuring that the lens can only slide into the transparent detection tube 104 longitudinally to avoid lateral blockage. The transparent detection tube 104 is fixedly installed at a 35° tilt angle to ensure the downward speed of the lens under its own weight and to avoid collision damage to the lens. The surface of the detection tube is made of high light transmittance optical glass, and the inner wall is polished to reduce frictional resistance.

[0034] During operation, the lenses to be tested are placed into the funnel 122 one by one from the top. Due to the limited diameter of the lower opening of the funnel 122, the lenses are automatically arranged in a single column and slide into the transparent detection tube 104 one by one. When the lens slides to the detection opening 105 area, it is temporarily stopped by the baffle 108 supported by the spring 110 until the detection opening is full. At this time, the three sets of LED color-adjusting lights 107 distributed on both sides and the bottom of the detection tube are activated by the control button on the display 117. By independently adjusting the color temperature and light intensity, the complex optical environment such as surgical shadowless lamp and endoscopic cold light source is simulated.

[0035] The lens detector 114 is a high-resolution industrial camera whose core function is to capture transmission and reflection images. The lens detector 114 focuses synchronously to capture transmission and reflection images of the lens under multiple illuminations and transmits them to the display 117. Microscopic scratches are identified by high color temperature strong light reflection imaging, and yellowing and fogging inside the lens are observed by low color temperature light penetration.

[0036] After the test is completed, pull up the handle 112 and pull the rod 111 to lift the baffle 108. The lens will slide into the bottom feed tube 119 and fall into the drawer 121 with rails. The baffle 108 will automatically reset under the action of the spring 110 and return to the blocking state, ready for the next batch of tests.

[0037] The minimum weighing capacity of the weighing device 116 is less than the weight of a single lens. The weighing device 116 is used to calculate the number of items to be tested in a given time, thus solving the problem of efficiency in manual counting. The entire device is powered by the battery in the battery box 115, which powers the LED color-changing light 107, the display 117 and the lens detector 114, ensuring that the equipment can work normally.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
