[0034] Refer to Figures 1 to 5 , an embodiment of the present utility model provides an endoscope tip structure. The endoscope tip structure includes a housing 100, an imaging module 200 and a bracket 300. The housing 100 is configured with a receiving cavity 110 having an opening at one end, and a light-transmitting wall 111 opposite to the opening is provided on the housing 100; the imaging module 200 is disposed in the receiving cavity 110. The imaging module 200 has a mounting end and an imaging end, and the imaging end is arranged facing the light-transmitting wall 111; the mounting end is fixedly connected to the bracket 300, and the bracket 300 is fixedly installed in the receiving cavity 110; wherein, the light-transmitting wall 111 is configured as a curved surface adapted to the imaging module 200 to improve the resolution of the imaging module 200.

[0035] The present utility model provides a distal end structure of an endoscope. Among them, a housing 100 is used to install and protect a camera module 200 and a bracket 300, and an accommodating cavity 110 with one end open is arranged on the housing 100 for arranging the camera module 200 in the accommodating cavity 110. A light-transmitting wall 111 is arranged on the housing 100 to facilitate the transmission of light so as to detect the part to be observed through the camera module 200. The bracket 300 is used to support the camera module 200 and is used for fixedly installing with the housing 100, thereby realizing the fixed connection between the camera module 200 and the housing 100. The light-transmitting wall 111 is configured as a curved surface adapted to the camera module 200 to change the angle of light emission. Through the above structural form, it is equivalent to adding a lens on the basis of the camera module 200, thereby improving the resolution of the camera module 200 and contributing to improving the optical performance of the endoscope.

[0036] It can be understood that the housing 100 in this embodiment can be made of high-strength engineering plastic by injection molding. The light-transmitting wall 111 is made of a light-transmitting plastic material. The camera module 200 can be a micro CCD camera or a micro CMOS camera, etc. One end where the camera is arranged is the imaging end, and the end facing away from the camera is the installation end, and the installation end is used for fixedly connecting with the bracket. For the bracket 300, an alloy material or a plastic material can be used. For the specific shape of the light-transmitting wall 111, it can be a general curved surface, or an aspherical surface, it can be a convex lens, or a concave lens. In one embodiment, the light-transmitting wall 111 is set as an aspherical surface, which can eliminate spherical aberration to the greatest extent, thereby providing higher optical quality.

[0037] As Figures 3 to 5 shown, in one embodiment, the distal end structure of the endoscope further includes a light source 400. The light source 400 is arranged on the bracket 300 and beside the camera module 200. The light source 400 is used to provide illumination for the imaging of the camera module 200. Further, the number of the light sources 400 is two, and the two light sources 400 are symmetrically arranged relative to the camera module 200. Such an arrangement has the effect of bilateral illumination, thereby providing a good illumination environment for the imaging component when detecting the part to be observed. In this embodiment, the light source 400 can adopt an LED lamp.

[0038] As Figure 1 and Figure 2As shown, in one embodiment, the housing 100 is composed of a light-transmitting area 120 and a light-shielding area 130 located on opposite sides. The light source 400 corresponds to the light-transmitting area 120. The light-transmitting wall 111 is located in the light-transmitting area 120. The light-shielding area 130 extends to the periphery of the light-transmitting wall 111 to separate the light source 400 and the imaging module 200. Aligning the light source 400 with the light-transmitting area 120 facilitates the passage of light. And the light-transmitting wall 111 is located in the light-transmitting area 120 and is adjacent to the light source 400. All other areas except the light-transmitting area 120 are set as the light-shielding area 130 to prevent light from escaping. At the same time, the light-shielding area 130 extends to the periphery of the light-transmitting wall 111 to separate the light source 400 and the imaging module 200, avoiding direct light on the imaging module 200, thereby improving the imaging quality and providing better auxiliary support for the doctor's operation.

[0039] Specifically, the light-shielding area 130 is made of black or dark-colored opaque plastic material, while the light-transmitting area 120 is made of transparent plastic material, and the housing 100 is formed by two-color injection molding process. Additionally, in one embodiment, the light-transmitting wall 111 can be made of plastic material or glass material. A window is reserved on the housing 100 during injection molding, and the light-transmitting wall 111 is installed at the reserved window.

[0040] As Figure 3 and Figure 5 As shown, in one embodiment, the bracket 300 is provided with a receiving groove 310 that penetrates the bracket 300 along a first direction of the bracket 300. Limiting grooves 311 are provided on two opposite side walls of the receiving groove 310. The imaging module 200 includes a main body and a base. The main body is disposed in the receiving groove 310, and both ends of the base are fixed in the corresponding limiting grooves 311. Further, both ends of the base are adhered to the corresponding limiting grooves 311. Through the above structural form, the reliability and stability of the connection between the imaging module 200 and the bracket 300 are ensured. In this embodiment, the first direction refers to the thickness direction of the bracket 300, and the first direction is perpendicular to the axis of the housing 100.

[0041] As Figure 4 As shown, in one embodiment, the bracket 300 is provided with two receiving notches 320. Two light sources 400 are fixedly installed in the corresponding receiving notches 320, and both sides of the receiving groove 310 communicate with the corresponding receiving notches 320. Through the above structural form, the occupied space of the light source 400 is reduced.

[0042] As Figure 1 As shown, in one embodiment, a limiting step 140 is provided on the outer peripheral surface of the housing 100; and / or, a plurality of spaced-apart limiting protrusions 150 are provided on the outer peripheral surface of the housing 100. Such settings facilitate the connection and limitation of the distal end structure of the endoscope with other endoscope components such as the snake bone, thereby ensuring the reliability of the connection.

[0043] The present utility model also provides an endoscope, which includes the above-described endoscope tip structure. By applying the endoscope tip structure with the above structure form in the endoscope, it is equivalent to adding a lens on the basis of the imaging module 200, thereby improving the resolution of the imaging module 200 and contributing to improving the optical performance of the endoscope.

[0044] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0045] The above-described embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
