[0032] The endoscope provided by the embodiment of the utility model is provided with a plurality of light outlets 312 on the second end of the endoscope tube body 200, and the plurality of light outlets 312 are provided around the lens 310, and the plurality of light outlets 312 are distributed on both sides of the longitudinal axis 311 on the lens 310, and the plurality of light outlets 312 located on one side of the longitudinal axis 311 and the plurality of light outlets 312 located on the other side opposite to the longitudinal axis 311 are alternately arranged and staggered, and the above-mentioned alternating arrangement and staggered arrangement enable the endoscope to obtain good brightness and improve the uniformity of illumination. In addition, the lens and light outlet arrangement of such a structure can also expand the visual range of the endoscope.

[0033] More specifically, if Figure 2 As shown, the lens system 300 further includes an optical fiber 330, one end of which is connected to the lens 310, and the other end of which is connected to the operating unit 100, and the optical fiber 330 is disposed inside the endoscope tube body 200. The optical fiber 330 is, for example, a fiber made of glass or plastic, and is used to transmit light.

[0034] like Figure 3 , Figure 4 and Figure 5 As shown, an optical fiber end face 331 is provided at one end of the optical fiber 330 close to the lens 310; wherein the optical fiber end face 331 is the end of the optical fiber 330, and transmits light through the lens 310 to illuminate the body cavity area to be observed. The lens system 300 also includes a beam splitter 340, wherein the beam splitter 340 is, for example, a beam splitter in a prism or cube shape or other shapes, and is used to refract and distribute light. The beam splitter 340 is arranged inside the endoscope tube body 200 and corresponds to a plurality of light outlets 312, and the beam splitter 340 is located between the optical fiber end face 331 and the plurality of light outlets 312.

[0035] More specifically, if Figure 3 As shown, the optical fiber end face 331 is arranged toward the corresponding light outlet among the multiple light outlets 312, and the angle a between the optical fiber end face 331 and the axis of the optical fiber 330 is less than 90°. Preferably, in the embodiment of the utility model, the optical fiber end face 331 is arranged toward the corresponding light outlet among the multiple light outlets 312, and the angle a between the optical fiber end face 331 and the axis 332 of the optical fiber 330 is less than 90°, wherein the angle a is, for example, 80°, 75°, 70°, and 65°, etc., and the angle of the optical fiber end face 331 is set so that the angle of the optical fiber end face 331 relative to the propagation direction of the light is different, so that the light enters the illumination area in different directions, and within a predetermined angle range, such as less than 90°, the target area is illuminated as evenly as possible.

[0036] The embodiment of the utility model improves the uniformity of illumination and expands the visual range of the endoscope by arranging the above-mentioned positions of the light outlet and arranging the above-mentioned positions and angles of the optical fiber end face 331, so that the endoscope tube body 200 can obtain more light output and more uniform illumination of the observation area when its diameter is constant; when the light output of the endoscope needs to reach a preset light output, the arrangement of the embodiment of the utility model can make the diameter of the endoscope tube body 200 smaller, that is, the embodiment of the utility model only needs an endoscope tube with a thinner diameter to obtain the preset light output. Such a design makes the working channel of the endoscope smaller and also improves the accuracy and safety of the doctor's operation.

[0037] like Figure 6 As shown, more specifically, a sleeve 350 is further provided in one end of the endoscope tube body 200 close to the multiple light outlets 312, and the sleeve 350 is sleeved around the beam splitter element 340 and the optical fiber 330, wherein the sleeve 350 is used to adjust the direction of the light so that the light is emitted from the desired emission direction of the light outlet.

[0038] like Figure 8 As shown, more specifically, the operating portion 100 further includes a card holder 110 , which is disposed at the bottom end of the operating portion 100 and opens downward.

[0039] like Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, more specifically, the storage module 500 includes: a storage member 510, a buckle 520, an L-shaped rod 530, a clamping block 540, a bearing 550, a rotating ring 560, a rotating member 570, a bearing 550, a sliding member 580 and an annular member 590. The circumferential surface of the storage member 510 is used to wrap around the endoscope tube body 200. One end of the buckle 520 is connected to the storage member 510, and the other end is clamped to the endoscope tube body 200, wherein the clamping block 540 is used to clamp the first end of the endoscope tube body 200; the L-shaped rod 530 is arranged on one side of the storage member 510 and connected to the center of the storage member 510. More specifically, the horizontal angle between the L-shaped rod 530 and the operating part 100 is 45°, which facilitates the first end of the endoscope tube body 200 to directly fit with the storage member 510, and prevents the endoscope tube body 200 from being damaged due to a large bending radius. The clamp block 540 is arranged at one end of the L-shaped rod 530 close to the operating part 100. The clamp block 540 is fixedly connected with the holder 110, so that the detachable storage part 510 can be directly removed after use and immersed and disinfected separately. The clamp block 540 is square in shape, and a raised elastic block (not shown) is arranged on the side surface of the clamp block 540. The square clamp block 540 can prevent the storage part 510 from rotating around the clamp block 540 as the axis, and prevent the clamp block 540 from rotating. The bearing 550 is located on the other side of the storage part 510 away from the L-shaped rod 530 and connected to the center of the other side of the storage part 510; the rotating ring 560 is sleeved on the bearing 550. One end of the rotating part 570 is connected to the rotating ring 560. One end of the sliding member 580 is connected to one end of the rotating member 570 away from the rotating ring 560; the annular member 590 is connected to one end of the sliding member 580 away from the rotating member 570, and the annular member 590 is arranged adjacent to the circumferential surface of the storage member 510, and the endoscope tube body 200 is inserted into the annular member 590, wherein the annular member 590 is used to guide the endoscope tube body 200 to be wound.

[0040] like Fig.10As shown, more specifically, the annular component 590 includes a first half ring 591 and a second half ring 592, one end of the first half ring 591 is hinged to one end of the second half ring 592, and the other end of the first half ring 591 is clamped to the other end of the second half ring 592 to form a full ring structure. In the embodiment of the utility model, after the endoscope is used, the various catheters connected to the operating part 100 are removed, and then the first end of the endoscope tube body 200 is pulled out from the buckle 520, and the clamp block 540 is pulled out from the holder 110. When the operating part 100 and the endoscope tube body 200 are placed separately, the storage part 510 is placed separately. Subsequently, these parts need to be initially cleaned and sent to the disinfection room for cleaning and disinfection. After the disinfection is completed, the clamp block 540 needs to be reinserted into the holder 110, and the buckle 520 connected to the first end of the endoscope tube body 200 is engaged with the annular part 590. By rotating the rotating part 570, the annular part 590 can be placed on the outer periphery of the storage part 510. When in use, the endoscope tube body 200 needs to be gradually released to effectively prevent it from being too long and contacting the outside.

[0041] More specifically, if Fig.10 As shown, a groove 571 is provided on the rotating member 570, and a sliding member 580 is inserted into the groove 571 and is slidably connected to the rotating member 570. In the embodiment of the utility model, the sliding member 580 is provided with a limiter that slides up and down. During the winding process of the endoscope tube body 200, when the bottom of the annular member 590 contacts the endoscope tube body 200 that has been wound once, it will slide upward, and the endoscope tube body 200 that needs to be wound later will be neatly stacked upward in a threaded shape. When the endoscope tube body 200 is wound and stored, the height of the annular member 590 naturally increases, so that the annular member 590 can slide up and down. More specifically, the storage module 500 also includes a rotation damper, which is arranged between the bearing 550 and the rotating ring 560. Among them, the function of the rotation damper is to make the rotating member 570 stop as it rotates.

[0042] In order to prevent the endoscope tube body 200 from swinging randomly and touching the unsterilized area, the embodiment of the utility model realizes the collection and coiling of the endoscope tube body 200 by setting the storage member 510, the annular member 590 and the L-shaped rod 530 to cooperate with each other. In addition, the bending radius of the endoscope tube body 200 is large when it is coiled through the layout, so as to prevent the optical fiber 330 inside the endoscope tube body 200 from breaking. The detachable storage member 510 design makes it easy to disinfect. When in use, the endoscope tube body 200 needs to be gradually released to effectively prevent the longer endoscope tube body 200 from contacting the outside, thereby avoiding the generation of contamination.

[0043] In addition, it can be understood that the aforementioned embodiments are merely illustrative descriptions of the present invention. Under the premise that the technical features do not conflict, are not contradictory, and do not violate the utility model purpose of the present invention, the technical solutions of the various embodiments can be arbitrarily combined and used in combination.
