Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

As shown in fig. 1 to 11, according to a first aspect of the present application, the present application provides an endoscope, which includes a window member 30, a first imaging assembly 10 and a second imaging assembly 20, wherein the first imaging assembly 10 and the second imaging assembly 20 are detachably attached and connected together, the window member 30 is connected to front ends of the first imaging assembly 10 and the second imaging assembly 20, and the endoscope can be decomposed into three independent components according to assembly requirements in a modularized thinking manner, so that each part of the endoscope is convenient to disassemble and assemble and convenient to use; meanwhile, the size and the placement form of the sensor are prevented from being limited due to the assembly problem of the endoscope, the manufacturing of the endoscope is facilitated, and the production cost of the endoscope can be effectively reduced.

Illustratively, the first imaging assembly 10 includes a first support 11, a first sensor 12 having a first photosurface, and a first optical element 13, and the second imaging assembly 20 includes a second support 21, a second sensor 22 having a second photosurface, and a second optical element 23, the first sensor 12 and the first optical element 13 being disposed on the first support 11, and the second sensor 22 and the second optical element 23 being disposed on the second support 21. The window 30 is provided with a mounting hole 311, the first bracket 11 and the second bracket 21 are connected to the rear end of the window 30, the positions of the first optical element 13 and the second optical element 23 correspond to the positions of the mounting hole 311, the first photosurface and the second photosurface are opposite, and the axis of the mounting hole is perpendicular to the axis of the first photosurface and the axis of the second photosurface.

The endoscope comprises a front endoscope and a rear endoscope, the front endoscope mainly refers to that the first sensor and the second sensor are arranged in an insertion tube of the endoscope placed in a patient, the rear endoscope refers to that the first sensor and the second sensor are arranged on a handle operation part, the front endoscope does not need to be placed in the patient, and the handle operation part and the insertion part can be separated. When the insertion tube is subjected to a washing and sterilizing process under a high temperature and high pressure environment after inspection, the use safety of the insertion tube is ensured. Therefore, in the front endoscope, the first imaging assembly 10 and the second imaging assembly 20 need to be sealed, which increases the manufacturing process of the endoscope, and the first imaging assembly 10 and the second imaging assembly 20 need to be aligned by focusing, and then sealed by welding or the like, which further increases the manufacturing process of the endoscope.

In addition, most endoscopes are tubular in structure, while avoiding irritation or other unpleasant experiences that occur when the endoscope is placed in the patient, and the outside diameter of the endoscope is as biased to a small size as possible, typically not exceeding 10mm. Along with the development trend of the endoscope imaging system, the endoscope imaging system has higher requirements for image definition, and gradually develops toward the 4K direction, the clearer the image is, the higher requirements for image quality and resolution are also provided, the sizes of the first imaging component 10 and the second imaging component 20 are also increased, and the maximum outer diameter of the endoscope not only limits the placement form and the maximum size of the first imaging component 10 and the second imaging component 20, but also indirectly limits the image resolution and the image quality of the first imaging component 10 and the second imaging component 20.

Therefore, the endoscope is split into the window component 30, the first imaging component 10 and the second imaging component 20, so that focusing alignment between the first imaging component 10 and the second imaging component 20 is facilitated, sealing connection between the window component 30 and the first imaging component 10 and the second imaging component 20 is facilitated, washing and disinfecting treatment can be performed on the endoscope under high-temperature and high-pressure environment, manufacturing process of the endoscope is simpler, meanwhile, the arrangement mode that the first light sensitive surface and the second light sensitive surface are opposite to each other is adopted, placement of the first sensor and the second sensor can be facilitated, the first sensor 12 and the second sensor 22 cannot be placed in the first bracket 11 and the second bracket 21 due to the size of the first sensor and the second sensor, the first sensor 12 and the second sensor 22 can be arranged along the length direction of the first bracket 11 and the second bracket 21, and the first light sensitive surface and the second surface can acquire images of specific light-sensitive objects or excited positions of the second optical element 23 through the first optical element 13 and the second optical element 23.

In an alternative embodiment, the axis of the first photosurface is coincident with the axis of the second photosurface, so that the first sensor 12 and the second sensor 22 can be oppositely arranged on the first bracket 11 and the second bracket 21, and the positions of the first sensor 12 and the second sensor 22 are the same, thereby facilitating focusing alignment between the first sensor 12 and the second sensor 22.

It should be noted that the axis of the first photosurface may be parallel to the axis of the second photosurface, which is not limited in this application.

In an alternative embodiment, window 30 includes a window 32, window 32 being mounted to mounting hole 311 and corresponding to the position of first optical element 13 and second optical element 23.

Alternatively, the number of the window sheets 32 and the number of the mounting holes 311 are two, the two window sheets 32 are correspondingly mounted in the two mounting holes 311, one window sheet 32 corresponds to the position of the first accommodating groove 112, the other window sheet 32 corresponds to the position of the second accommodating groove 212, so that the first sensor 12 can obtain the image light reflected or excited by the specific part of the inspection object through one window sheet 32, and the second sensor 22 can obtain the image light reflected or excited by the specific part of the inspection object through the other window sheet 32.
