[0003] Currently, when testing the basic optical performance of 3D fluorescence endoscopes, the endoscope is typically mounted on a base. However, since the base on which the endoscope is mounted lacks adjustment, its height cannot be precisely adjusted according to testing requirements, limiting its applicability and making the testing process difficult to adapt to diverse needs. Therefore, to address these issues, we designed a device for testing the optical performance of 3D fluorescence endoscopes. Utility Model Content

[0012] A further improvement is that a notch is provided on the bottom surface of the installation compartment for the assembly chassis to enter and exit, and a notch is provided on the surface of the installation base for the adjustment column seat to enter and exit.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 and Figure 3 As shown, a device for detecting the optical performance of a 3D fluorescence endoscope includes a mounting base 1, a set of blocks 11 provided on the mounting base 1, and a mounting chamber 3 connected to the block 11. The mounting chamber 3 is connected to the set of blocks 11 by fixing bolts to achieve assembly and disassembly.

[0025] The interior of the mounting base 1 is provided with an inner cavity 101, the interior of the mounting chamber 3 is provided with an assembly chassis 2, the middle portion of the assembly chassis 2 is raised upward, and a positioning threaded column 21 is provided on the outer wall of the raised portion;

[0026] Specifically, as a preferred embodiment, the inner wall of the mounting chamber 3 is provided with a plurality of auxiliary bayonet holes 31. The top surface of each auxiliary bayonet hole 31 extends outward. By allowing the card block on the endoscope housing to be firmly engaged in the auxiliary bayonet hole 31, this design can prevent the endoscope from deflecting during the inspection process, thereby improving the accuracy of the inspection results.

[0027] like Figure 2As shown, when implemented, it includes: a fine-tuning component 4, which includes a fine-tuning screw 41 that is vertically rotatable and arranged in the inner cavity 101, a sub-gear 42 connected to the bottom end of the fine-tuning screw 41, a DC servo motor 43 connected to one side of the inner cavity 101, a main gear 44 connected to the main shaft of the DC servo motor 43 and meshing with the sub-gear 42, and an adjustment column seat 45 that is slidably arranged in the inner cavity 101 and threadedly sleeved on the fine-tuning screw 41. The bottom surface of the assembly chassis 2 is connected to the top surface of the adjustment column seat 45. By starting the DC servo motor 43 to rotate it clockwise / counterclockwise, the main gear 44, sub-gear 42 and fine-tuning screw 41 are driven to rotate, thereby driving the endoscope and the adjustment column seat 45 to adjust the height. This feature can meet the requirements for adjusting the height of the endoscope under different detection needs;

[0028] Specifically, as a preferred embodiment, the inner cavity 101 is divided into a vertical adjustment section 102 and a driving section 103. The inner wall of the adjustment section 102 is provided with a limiting slide groove 104 on both sides. The top surface of the limiting slide groove 104 extends out. The side surface of the adjustment column seat 45 and the limiting slide groove 104 are connected to the bottom surface of the installation chamber 3. A slot 5 for the assembly chassis 2 to enter and exit is opened. The surface of the installation base 1 is also provided with a slot 5 for the adjustment column seat to enter and exit.

[0029] Specifically, as a preferred embodiment, the bottom surface of the mounting bin 3 and the surface of the mounting base 1 are both provided with slots 5 for the assembly chassis 2 to enter and exit. The bottom surface of the assembly chassis 2 is connected to a socket 22, which is inserted into the top surface port of the adjustment column seat 45. The outside of the adjustment column seat 45 is connected to the socket 22 by a fixing bolt for assembly and disassembly of the assembly chassis 2.

[0030] like Figures 1 to 3 As shown, in this embodiment, the application document is for an auxiliary mounting device, the purpose of which is to facilitate the adjustment of the height of a 3D fluorescent endoscope to meet the detection requirements of different optical performances. The detection method and principle are both existing technologies and will not be described in detail in this embodiment. The shape of the endoscope in the application document is cylindrical in this embodiment. The housing of the endoscope is provided with a block for installation in conjunction with the auxiliary bayonet 31, and a threaded groove is provided on the bottom surface. In addition, it should be noted that this application document only targets existing devices for detecting the optical performance of 3D fluorescent endoscopes. Since the base on which the endoscope is installed does not have an adjustment function, its height cannot be accurately adjusted according to the detection requirements, thereby limiting its scope of application and making it difficult for the detection process to adapt to diverse needs. This improves the shortcomings and does not involve improvements in other aspects. The following is an introduction to the working principle of the device for detecting the optical performance of a 3D fluorescent endoscope:

[0031] To use this new device, first secure the mounting chamber 3 to the inside of a set of blocks 11 using the fixing bolts. Next, activate the DC servo motor 43, rotating it clockwise to drive the main gear 44, which in turn rotates the secondary gear 42 and the fine-tuning screw 41. This movement simultaneously causes the adjustment column 45 to rise, pushing the assembly chassis 2 out of the notches 5 of the mounting chamber 3 and the mounting base 1 until its height exceeds the opening of the mounting chamber 3.

[0032] The operator then screws the bottom of the endoscope housing onto the positioning threaded post 21 to secure the endoscope. At this point, the block on the endoscope housing aligns with the auxiliary bayonet 31. The operator then rotates the DC servo motor 43 counterclockwise, retracting the adjustment column 45, the rotating base 22, the assembly chassis 2, and the endoscope into the mounting compartment 3 until the block on the endoscope housing securely engages the auxiliary bayonet 31. This design prevents the endoscope from drifting during inspection, thereby improving the accuracy of the test results.

[0033] During the inspection process, if adjustment is required, the DC servo motor 43 can be restarted to rotate clockwise / counterclockwise, driving the main gear 44, the secondary gear 42 and the fine-tuning screw 41 to rotate, thereby driving the endoscope and the adjustment column 45 to adjust the height. This feature enables the device to meet the requirements for adjusting the height of the endoscope under different inspection needs.

[0034] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
