Detailed Description

For the purpose of illustrating the construction and features of the invention in detail, reference should be made to the following description of the preferred embodiments taken in conjunction with the accompanying drawings.

Referring to fig. 3 to 6, fig. 3 is a perspective view showing the insertion section tip of the endoscope of the present invention. FIG. 4 is a front view of the insertion section tip of the endoscope of the present invention. FIG. 5 is a schematic diagram of the construction of an embodiment of the washer in the endoscope of the present invention. FIG. 6 is a schematic structural view of another embodiment of the washer in the endoscope of the present invention. The invention provides an endoscope 10, the insertion head end of which is composed of an outer tube 1, a CCD/CMOS cable 2 accommodated in the outer tube 1, a light guide bundle 3, a forceps tube 4 and a cleaner 8 capable of being inserted into the forceps tube 4. The CCD/CMOS objective lens 21 is arranged at the end of the CCD/CMOS cable 2 and is exposed out of the front end of the outer tube 1; the end 31 of the light guide bundle 3 is exposed out of the front end of the outer tube 1; the end 41 of the forceps channel 4 is exposed at the front end of the outer tube 1. The washer 8 can be inserted into the forceps tube 4, and the distal end 81 of the washer 8 can be exposed to the distal end of the outer tube 1 to clean the CCD/CMOS objective lens 21.

Referring to fig. 5, one embodiment of the washer 8 is illustrated as a brush structure. The front end 81 of the cleaner 8 is a brush head and the rear end 82 of the cleaner 8 is a handle. When the cleaning device 8 is inserted into the forceps channel 4, the front end 81 may extend from the end 41 of the forceps channel 4 to the front end of the outer tube 1 for brushing the outer surface of the CCD/CMOS objective lens 21. The tip 82 is conveniently held by the operator.

It will be appreciated that the bore of the outer profile of the body of the washer 8 of the brush arrangement is smaller than the bore of the lumen of the forceps channel 4 to ensure that the washer 8 can be conveniently inserted into the forceps channel 4. The outer contour caliber of the end 82 of the cleaning device 8 is larger than the inner cavity caliber of the forceps pipe 4, so that the cleaning device 8 is not completely contained in the forceps pipe 4, namely the end 82 is always positioned outside the forceps pipe 4, and the use safety is ensured.

The front end 81 of the washer 8 is bent at a predetermined angle (approximately 90 degrees, for example, 90 degrees ± 5 degrees) with respect to the main body of the washer 8 in a free state; also, the front end 81 of the washer 8 has elasticity with respect to the main body of the washer 8, and can be retracted/extended downward, extended forward, or retracted backward in the lumen of the forceps tube 4.

Referring to fig. 6, another embodiment of the washer 8 is illustrated as a pipe structure for transporting the gas/liquid for washing. The front end 81 of the washer 8 is a nozzle, and the rear end 82 of the washer 8 is a connector. When the cleaning device 8 is inserted into the forceps tube 4, the front end 81 of the cleaning device 8 may protrude from the tip 41 of the forceps tube 4 to the front end of the outer tube 1 for washing the outer surface of the CCD/CMOS objective lens 21. The end 82 of the washer 8 is conveniently externally connected to a pump air/fluid hose.

It will be appreciated that the outer contour of the body of the washer 8, together with the front end 81 of the washer 8, is smaller in caliber than the lumen of the forceps channel 4 to ensure that the washer 8 can be conveniently inserted into the forceps channel 4. The outer contour caliber of the end 82 of the cleaning device 8 is larger than the inner cavity caliber of the forceps pipe 4, so that the cleaning device 8 is not completely accommodated in the forceps pipe 4, namely, the end 82 of the cleaning device 8 is always positioned outside the forceps pipe 4, and the use safety is ensured.

It should be noted that in some embodiments, the brush structure of fig. 5 and the tube structure of fig. 6 are alternatively inserted into the forceps tube 4 for cleaning, for example: brushing with only the brush structure of fig. 5, or rinsing with only the tube structure of fig. 6, or brushing with the brush structure of fig. 5 first followed by rinsing with the tube structure of fig. 6, or rinsing with the tube structure of fig. 6 first followed by brushing with the brush structure of fig. 5; in some embodiments, the brush structure of fig. 5 and the tube structure of fig. 6 may be inserted into the forceps tube 4 at the same time for cleaning.

Compared with the prior art, the endoscope 10 of the invention can not only meet the function of cleaning the CCD/CMOS objective lens 21 by the cleaner 8, but also save the space occupied by the fixed nozzle 51 by removing the fixed nozzle 51 structure in the traditional endoscope 10a and by means of the cleaner 8 which can be inserted into the forceps pipeline 4, thereby being beneficial to the large-size of the CCD/CMOS objective lens 21 and further being beneficial to the improvement of the imaging pixels of the endoscope under the limitation of the determined external dimension of the outer tube 1.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention. All such modifications and variations are intended to be included herein within the scope of this disclosure and the present invention.
