Detailed Description

The following description provides many different embodiments, or examples, for implementing different features of the invention. The particular examples set forth below are illustrative only and are not intended to be limiting.

Endoscopes are often used to view lesions that are not visible on X-rays, and provide sufficient diagnostic information to a physician to treat the disease, but application of the same endoscope between different patients can easily result in cross-contamination. Although the disposable endoscope can avoid the problem of cross infection, the disposable endoscope has high use cost and is not beneficial to environmental protection. The endoscope can be a fiber endoscope and an electronic endoscope.

The fiber endoscope consists of an endoscope body and a cold light source, wherein a light guide beam and an image guide beam are arranged in the endoscope body, and the light guide beam is used for transmitting light generated by the cold light source to the surface of an observed object and illuminating the surface of the observed object; the image guide bundle is formed by arranging tens of thousands of optical fibers with the diameter of less than 1 micron into a bundle in sequence, one end of the image guide bundle is aligned with the ocular lens, the other end of the image guide bundle is aligned with the surface of a focus, and a doctor can visually see the position of the focus through the ocular lens.

The electronic endoscope uses a photosensitive integrated circuit camera system (CCD chip for short) to transmit images instead of optical fiber. The CCD chip can make focus image undergo the processes of point-by-point conversion, line-by-line conversion, frame-by-frame conversion, storage and transmission successively by means of CCD area array, and its output end can produce a time sequence video signal related to focus image, and said time sequence video signal can be transferred into external circuit conversion processing system by means of cable, then undergone the processes of sampling, A/D conversion, digital signal processing, D/A conversion and TV signal coding, and finally restored into focus image and related literal information for observation on the monitor. Some electronic endoscopes are also provided with a micro-integrated circuit sensor, which feeds back observed information to a computer, and which can not only obtain morphological diagnostic information of tissues and organs, but also measure various physiological functions of the tissues and organs. Compared with a fiber endoscope, the electronic endoscope has higher image quality, high brightness and higher resolution, and can detect finer lesions; and the electronic endoscope has thinner outer diameter, thereby being more convenient for the operation of doctors. Therefore, the electronic endoscope has wider application prospect.

In the endoscope, the most expensive part is the camera module, and camera module among the prior art wholly encapsulates in the distal end of endoscope, if can retrieve the camera module will be great reduction endoscope discard cost.

In view of this, an embodiment of the present invention, as shown in fig. 1 and 2, provides an all-in-one imaging assembly, where the all-in-one imaging assembly 1 includes: an objective lens 11, an image sensor 12, and an image guide beam 13; the image guide bundle 13 comprises a probe end 131 and a handle end 132;

as shown in fig. 1, a probe end 131 of the image guide bundle 13 is fixedly connected to the objective lens 11, a handle end 132 of the image guide bundle 13 is fixedly connected to the image sensor 12, and the image guide bundle 13 is an optical fiber;

in the above scheme, an optical fiber is adopted as the image guide bundle 13 according to the optical total reflection principle. One end of the optical fiber is fixedly connected to the objective lens 11, and the other end of the optical fiber is fixedly connected to the image sensor 12.

In practical application, the objective lens 11 is packaged at the probe end 131 of the distal end of the endoscope, the image sensor 12 is contained at the handle end 132 of the proximal end of the endoscope, and the optical fiber is packaged in the endoscope body; the distal objective 11 of the endoscope transmits the collected optical signal of the focus to the image sensor 12 through the optical fiber, and the image sensor 12 converts the received optical signal in a series, and finally generates an image signal to be displayed on the display.

Preferably, the outside of the optical fiber is coated with a film with a low refractive index to ensure total reflection of the light transmitted by the optical fiber.

It should be noted that, in the conventional manner in the prior art, both the objective lens 11 and the image sensor 12 are packaged at the distal end of the endoscope, and the objective lens 11 and the image sensor 12 are only connected to one end of the image guide bundle 13; therefore, it is not easy for those skilled in the art to fixedly connect the objective lens 11 and the image sensor 12 to both ends of the image guide beam 13, respectively. In the prior art, both the objective lens 11 and the image sensor 12 are packaged at the far end of the endoscope, and the signal generated by the sensor of the image sensor 12 is converted into an electric signal which can only be transmitted in an electric signal transmission line; therefore, the image guide bundle in the prior art must adopt an electrical signal transmission line, and therefore, it is not easy for those skilled in the art to replace the image guide bundle 13 with an optical fiber.

As shown in fig. 2, or the objective lens 11 is connected with the image sensor 12 as a whole, the probe end 131 of the image guide bundle 13 is fixedly connected with the image sensor 12, and the image guide bundle 13 is an electrical signal transmission line.

In the above scheme, the objective lens 11 and the image sensor 12 are integrally packaged at the probe end 131 of the distal end of the endoscope, and the light guide beam is packaged in the endoscope main body; the objective lens 11 at the distal end of the endoscope directly transmits the collected optical signal of the target object to the image sensor 12, and the image sensor 12 converts the received optical signal into an electrical signal, transmits the electrical signal to the final generated image signal through the image guide beam 13, and displays the image signal on the display.

It should be noted that the present embodiment is the biggest difference from the prior art in that: the imaging components of the endoscope in the prior art are not integrally arranged, and cannot be integrally pulled out of the endoscope, but the imaging components in the two schemes are integrally arranged, that is, the objective lens 11, the image sensor 12 and the image guide bundle 13 form a whole, and the imaging components can be contained in the endoscope as a single component for use, or can be integrally pulled out of the endoscope, and are reused after being sterilized. Therefore, the endoscope imaging component can be independently recycled, and the disposal cost of the endoscope is greatly reduced.

Further, as shown in fig. 3-6, the integrated imaging assembly 1 further includes a lens mount 14, and the objective lens 11 is accommodated in the lens mount 14.

In the above-mentioned solution, the lens holder 14 is provided to facilitate the mounting and dismounting of the objective lens 11 at the distal end of the endoscope. In practical application, the objective lens 11 is accommodated in the lens mount 14, and the objective lens 11 and/or the image sensor 12 can be fixed only by connecting the lens mount 14 with the distal end of the endoscope.

In another embodiment of the present invention, as shown in fig. 3 to 6, an endoscope is provided, which includes an endoscope main body 2 and the aforementioned integrated imaging assembly 1, wherein an imaging channel 21 is provided in the endoscope main body 2, the integrated imaging assembly 1 is accommodated in the imaging channel 21, and the integrated imaging assembly 1 can be integrally withdrawn from the imaging channel 21.

In the scheme, the imaging assembly is accommodated in the imaging channel 21 of the endoscope, and when the imaging assembly is recovered, the integrated imaging assembly 1 is integrally pulled out of the imaging channel 21, so that the imaging assembly 1 is recycled, and the whole operation is simple and convenient. Compared with the endoscope in the prior art, the endoscope in the embodiment is abandoned with low cost, and is more environment-friendly and economical.

Further, the endoscope main body 2 includes a probe side 22 and a handle side, and the imaging channel 21 communicates the probe side 22 and the handle side; in the following scheme, two arrangements of the integrated imaging assembly 1 in the endoscope are given. In particular, the amount of the solvent to be used,

the objective lens 11 is arranged on the probe side 22, the image sensor 12 is arranged on the handle side, and the image guide bundle 13 is accommodated in the imaging channel 21; by the arrangement mode, the integral recovery of the imaging assembly can be realized; secondly, since the image sensor 12 is located at the handle side of the endoscope, the risk of contamination of the image sensor 12 is further avoided, facilitating separate recycling of the image sensor 12.

Or the objective lens 11 and the image sensor 12 are both arranged on the probe side 22 of the imaging channel 21, the probe end 131 of the image guide bundle 13 is connected with the image sensor 12, and the image guide bundle 13 is accommodated in the imaging channel 21; thereby realizing the integral recovery of the imaging assembly.

Further, as shown in fig. 5, the handle side of the endoscope is provided with an insertion port 231, and the integrated imaging module 1 can be integrally passed through the imaging channel 21 from the insertion port 231;

and/or the probe side 22 of the endoscope is provided with an insertion port 231, the integrated imaging assembly 1 being extractable out of the imaging channel 21 from the insertion port 231.

In the above-described embodiment, the entire integrated imaging module 1 is removed from the endoscope through the insertion port 231, thereby realizing recycling of the imaging module 1. The insertion port 231 may be provided at a handle side of the endoscope main body (see fig. 5), or may be provided at a probe side 22 of the endoscope main body (not shown).

Of course, a detachable handle cover (not shown) is provided at the handle-side end of the endoscope, and the handle cover is detachably connected to the handle of the endoscope. When the integrated imaging module needs to be pulled out from the handle side of the endoscope main body 1, the handle cover needs to be opened first.

Further, as shown in fig. 7, the endoscope further includes a lens cover 24, a first connecting structure 141 is disposed on the lens holder 14, a second connecting structure 241 is disposed on the lens cover 24, and the lens holder 14 is abutted to the lens cover 24 by the connection between the first connecting structure 141 and the second connecting structure 241.

When the integrated imaging assembly 1 is received in the endoscope, the imaging assembly needs to be positioned. Specifically, positioning of the integrated imaging assembly 1 within the endoscope body 2 is accomplished by positioning the lens mount 14 relative to the endoscope lens cover 24 (i.e., the first and second attachment structures 141 and 241).

As for the structure for realizing the connection between the lens holder 14 and the lens cover 24, a snap-fit structure is available; if the lens holder 14 (or the lens cover 24) is provided with the elastic protrusion, and the lens cover 24 (or the lens holder 14) is provided with the groove at the corresponding position, when the elastic protrusion is clamped in the groove, the lens holder 14 and the lens cover 24 are relatively fixed; when the lens mount 14 (or the lens cover 24) is pulled, the elastic buckle is separated from the groove, so that the lens mount 14 and the lens cover 24 are separated, and at the moment, the integral imaging assembly 1 can be separated from the endoscope main body 2.

Further, a guiding structure (not shown) is disposed on the imaging channel 21, and the guiding structure is used for guiding the integrated imaging assembly 1 through the imaging channel 21.

When the integrated imaging module 1 is detached from the endoscope main body 2 from the handle side of the endoscope, the objective lens 11 (or "objective lens 11 and image sensor 12") needs to pass through the entire imaging channel 21. A guide structure is arranged in the imaging channel 21, so that the integrated imaging component 1 can be guided to pass through the imaging channel 21 according to a preset path, and the integrated imaging component 1 can be smoothly pulled out.

In the above-described embodiment, the illumination module 25 is provided integrally with the integrated imaging module 1, and when the integrated imaging module 1 is separated from the endoscope, the illumination module 25 can be separated at the same time, and the illumination module 25 can be recycled. Preferably, the illumination assembly 25 may be provided in plural, arranged in the circumferential direction of the objective lens 11.

In another embodiment of the present invention, as shown in fig. 9, an endoscope retraction method as described above is provided, wherein the arrow indicates the direction of retraction of the integrated imaging assembly. The method comprises the following steps:

step S01: integrally withdrawing the integrated imaging assembly 1 from the endoscope body 2;
