Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, specifically to a medical photodynamic multispectral electronic endoscope. Background Technology

[0002] Medical photodynamic multispectral electronic endoscopes combine photodynamic diagnostic technology and multispectral imaging technology, providing doctors with richer diagnostic information and helping to improve the accuracy of disease diagnosis and the detection rate of early lesions. In actual clinical examinations, different examination sites and lesion conditions often require eyepieces with different magnifications and characteristics (such as depth of field and field of view) to obtain the best image effect and diagnostic basis. However, traditional eyepiece replacement methods are usually cumbersome, requiring complex disassembly and installation steps, which not only wastes a lot of examination time, but also seriously affects diagnostic efficiency in emergency situations or when a rapid switch of observation angle is required, and may even delay the diagnosis. Utility Model Content

[0003] In view of the problems existing in the current medical photodynamic multispectral electronic endoscope, this utility model is proposed.

[0004] Therefore, the purpose of this invention is to provide a medical photodynamic multispectral electronic endoscope, which solves the problems of existing medical photodynamic multispectral electronic endoscopes.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A medical photodynamic multispectral electronic endoscope includes an eyepiece base and an objective lens. One end of the eyepiece base is connected to a light guide, and the objective lens is mounted on the end of the light guide away from the eyepiece base. The eyepiece base has a mounting cavity inside, and an opening is formed on one side of the mounting cavity. A mounting shell is snapped into the mounting cavity. Both ends of the mounting shell have through holes, and an eyepiece body is snapped into the mounting shell. The inner walls of both ends of the eyepiece base away from the opening have sliding grooves. A sliding rod is fixedly installed inside the sliding groove. A slider is movably sleeved on the rod wall of the sliding rod. A transmission mechanism is provided on one side of the slider to drive the mounting shell to move into the eyepiece base.

[0007] Preferably, the transmission mechanism includes a transmission rod and a spring. The transmission rod is disposed between the slider and the mounting shell. Both ends of the transmission rod are rotatably connected to connecting blocks via pins. One side of the connecting block is fixedly connected to the slider, and the other side of the connecting block is fixedly connected to the mounting shell. The spring is movably sleeved on the wall of the slider. One end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the inner wall of the corresponding groove.

[0008] Preferably, both the slider and the groove have rectangular cross-sections.

[0009] Preferably, a sealing plate is fixedly provided on the side of the mounting shell near the opening, and the sealing plate is engaged with the opening.

[0010] Preferably, the outer wall of the sealing plate is provided with a groove.

[0011] Preferably, a rubber pad is provided inside the mounting housing.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] This invention allows the mounting shell to be pulled out of the eyepiece holder by pulling the sealing plate. After replacing the eyepiece body, the mounting shell is released, and the spring force pushes the slider away from the mounting shell, causing the slider to rotate the corresponding transmission rod towards verticality. This automatically pulls the mounting shell into the eyepiece holder, enabling quick replacement of different eyepieces in a short time without complicated disassembly and installation operations, greatly saving examination time and improving the efficiency of clinical examinations.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model discloses a medical photodynamic multispectral electronic endoscope.

[0022] Reference Figure 1-3 A medical photodynamic multispectral electronic endoscope includes an eyepiece base 1 and an objective lens 3. One end of the eyepiece base 1 is connected to a beam guide 2. The objective lens 3 is mounted on the end of the beam guide 2 away from the eyepiece base 1. The eyepiece base 1 has an internal mounting cavity with an opening on one side. A mounting shell 5 is snapped into the internal cavity. Both ends of the mounting shell 5 have through holes. An eyepiece body 6 is snapped into the internal cavity of the mounting shell 5. Sliding grooves are formed on the inner walls of both ends of the side of the eyepiece base 1 away from the opening. A sliding rod 8 is fixedly installed inside the sliding groove. A slider 7 is movably sleeved on the wall of the sliding rod 8. The cross-section of both the slider 7 and the sliding groove is rectangular, so that the slider 7 cannot rotate, i.e., it can slide stably.

[0023] Reference Figure 1-3 A transmission mechanism is provided on one side of the slider 7 to drive the mounting shell 5 into the eyepiece holder 1. The transmission mechanism includes a transmission rod 9 and a spring 12. The transmission rod 9 is located between the slider 7 and the mounting shell 5. Both ends of the transmission rod 9 are rotatably connected to connecting blocks 10 via shaft pins 11. One connecting block 10 is fixedly connected to the slider 7, and the other connecting block 10 is fixedly connected to the mounting shell 5. The spring 12 is movably sleeved on the wall of the slide rod 8. One end of the spring 12 is fixedly connected to the slider 7, and the other end of the spring 12 is fixedly connected to the inner wall of the corresponding slide groove. A sealing plate 4 is fixedly provided on the side of the mounting shell 5 near the opening. A groove is opened on the outer wall of the sealing plate 4 to facilitate pulling the sealing plate 4. The sealing plate 4 is engaged with the opening to ensure the light-blocking effect of the eyepiece holder 1. A rubber pad is provided inside the mounting shell 5 so that the eyepiece body 6 can be stably engaged inside the mounting shell 5.

[0024] In this invention, when in use, pulling the sealing plate 4 will pull the mounting shell 5 out of the eyepiece holder 1. After replacing the eyepiece body 6, releasing the mounting shell 5 will cause the spring force of the spring 12 to push the slider 7 away from the mounting shell 5, causing the slider 7 to drive the corresponding transmission rod 9 to rotate towards verticality, thus automatically pulling the mounting shell 5 into the eyepiece holder 1. This allows for quick replacement of different eyepieces in a short time without complicated disassembly and installation operations, greatly saving examination time and improving the efficiency of clinical examinations.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
