As shown in fig. 1, an endoscope 100 may be used to view lesions of organs within a human body. The endoscope 100 includes an operation element 1, an insertion portion 2, and a head end structure 3. Wherein the operating element 1 is arranged at one end of the insertion part 2, and the head end structure 3 is arranged at the other end of the insertion part 2.

In this embodiment, the insertion portion 2 has a tubular shape, which can be bent arbitrarily. When the endoscope 100 is used, the head end structure 3 and the insertion part 2 enter the human body together, and medical staff can control the insertion part 2 and the head end structure 3 through the operation member 1 so as to obtain images of lesion parts in the human body.

The head end structure 3 includes a head end housing 30, as shown in fig. 2, the head end housing 30 being approximately cylindrical in shape overall, exhibiting a "mushroom" shape. The head end housing 30 has opposed first and second end faces 31, 32.

As shown in fig. 3, the head end housing 30 is provided with a first channel 33 and a second channel 34 penetrating the first end surface 31 and the second end surface 32, the first channel 33 is used for accommodating the camera assembly, and the second channel 34 is used for fluid passing through.

Referring to fig. 2 in combination with fig. 4, the first end surface 31 of the head end housing 30 is provided with a raised area 310, the first channel 33 is formed with a first through hole 330 for accommodating a slide in the raised area 310, and the second channel 34 is formed with a second through hole 340 outside the raised area 310.

In actual use, the camera assembly is mounted in the first channel 33, the lens of the camera assembly is aligned with the first through hole 330, and a glass slide is covered in the first through hole 330. The glass slide is a transparent glass sheet, plays a role in protecting the lens, and does not shade the shooting of the lens. The head end housing 30 enters the inside of the human body together with the insertion portion 2, and the lens captures an image of a lesion in the inside of the human body. The opaque body fluid or blood is inevitably adhered to the glass slide, so that an image shot by the lens is blurred, or an image of a part to be detected cannot be shot at all. At this time, the medical staff can control the operation member 1 to enable the liquid to wash the first through hole 330 through the second through hole 340 via the second channel 34, and wash away the dirt adhered to the glass slide, so that the endoscope 100 can be used normally, and the definition of the image is ensured.

The liquid used for flushing the first through hole 330 may be any one of normal saline, 2% sodium bicarbonate solution, or pure water, as long as the flushing liquid meets medical standards.

Because the first through hole 330 is located in the bulge area 310, the washed cleaning water flows out of the bulge area 310 and flows around, so that no water is left at the first through hole 330, that is, no water is left on the glass slide, the definition of the image is ensured, and the endoscope 100 can be used normally.

The head end housing 30 has a bulge region 310 on the first end surface 31, a first through hole 330 for accommodating a slide glass is formed in the bulge region 310, and fluid is flushed through the second through hole 340 at the first through hole 330 via the second passage 34. The first through hole 330 is arranged in the bulge area 310, the washed cleaning water flows downwards out of the bulge area 310, no accumulated water is left at the first through hole 330, the problem of unclear vision at the camera is solved, and normal use of the endoscope 100 is ensured.

In some of these embodiments, the raised area 310 has a height from the first end surface 31 of 0.1mm to 1mm. Such a height interval can ensure that the cleaning water smoothly flows to the periphery of the raised area 310 after the first through hole 330 is washed, and can prevent the raised area 310 from being excessively high when the head end housing 30 is inserted into a human body, thereby causing injury to the human body.

It will be appreciated that the raised area 310 transitions with the first end surface 31 through an arcuate ramp 35, as shown in fig. 2. The rinsed cleaning water flows from the raised area 310 to the periphery, and the transition between the raised area 310 and the first end surface 31 through the arc-shaped slope 35 helps the cleaning water smoothly flow out of the raised area 310 and out of the raised area 310.

In addition, when the cleaning water flows from the slide to the arc slope 35, the water drops at the arc slope 35 can pull out the water drops remained on the slide from the slide under the action of tension, so that the quality of the image shot by the camera is prevented from being influenced due to the existence of the water drops on the slide.

The design of the arcuate ramp 35 not only accelerates the flow of wash water out of the raised area 310, but also pulls most of the wash water out of the slide by tension, further ensuring proper use of the endoscope 100.

As shown in fig. 2, the wall surface of the first through hole 330 is provided with a flange 36, and the flange 36 is annular as a whole. The first through hole 330 is coaxial with the flange 36, and an end face of the flange 36 is configured as a contact face for abutting contact with a slide. That is, the slide is inserted into the first through hole 330, and the flange 36 supports the slide.

The distance between the contact surface of the flange 36 for abutting contact with the slide and the first end surface 31 is equal to the thickness of the slide. In this way, the slide is flush with the first end face 31, and the washed wash water does not accumulate between the slide and the first end face 31.

Referring to fig. 2 in combination with fig. 4, an annular protrusion 37 is protruded around the second through hole 340, and the height between the annular protrusion 37 and the first end surface 31 is greater than the height between the ridge area 310 and the first end surface 31.

Because the height between the annular protrusion 37 and the first end surface 31 is greater than the height between the raised area 310 and the first end surface 31, when the flushing water flows out from the second through hole 340, the flushing water at a higher position flows to the raised area 310 at a lower position to clean the first through hole 330 in the raised area 310, so that the flushing water flowing through the second channel 34 can be guided to the raised area 310 for flushing operation by utilizing the dead weight of the flushing water under the condition of lower water pressure.

Of course, the side of the annular projection 37 facing away from the first end face 31 is configured as a sloping surface sloping downward toward the first through hole 330. After the washing water flows out of the second through holes 340, the washing water may flow along the slope toward the raised area 310 at the lower position, and wash the first through holes 330 in the raised area 310. The slope design further provides a guiding function for the wash water, and further purposefully guides the wash water to the first through hole 330 for cleaning the slide.

Further, a part of the annular protrusion 37 is located at the edge of the head end housing 30, and a side of the annular protrusion 37 facing away from the first end face 31 is inclined downward from a side near the edge of the head end housing 30 toward the first through hole 330. This configuration helps to purposefully direct wash water even further to the first through hole 330 for cleaning slides.

In some embodiments, as shown in fig. 2, the head end housing 30 defines a third passageway 38 extending through the first and second end surfaces 31, 32, the third passageway 38 being accessible for surgical instruments to perform surgical procedures.

After the endoscope 100 reaches the lesion, the medical staff can operate the surgical instrument in the third channel 38 through the operation member 1 to extend the surgical instrument to perform the related operation in the human body.

In still other embodiments, as shown in FIG. 2, the head end housing 30 defines a fourth passage 39 extending through the first and second end surfaces 31, 32, the fourth passage 39 being configured for fluid passage for a spray operation.

After the endoscope 100 is inserted into the human body, the liquid can be sprayed from the fourth channel 39 to spray the inside of the human body.

The head end housing 30 may be made of medical grade plastic, which may be integrally formed by injection molding.

The head end housing 30 has a first channel 33 and a second channel 34 penetrating the first end surface 31 and the second end surface 32, the first channel 33 is used for accommodating a camera assembly, and the second channel 34 is used for fluid passing through.

The first end surface 31 of the head end housing 30 is provided with a bulge area 310, the first channel 33 is provided with a first through hole 330 for accommodating a slide glass in the bulge area 310, and the second channel 34 is provided with a second through hole 340 outside the bulge area 310.

In actual use, the camera assembly is mounted in the first channel 33, the lens of the camera assembly is aligned with the first through hole 330, and a glass slide is covered in the first through hole 330. The glass slide is a transparent glass sheet, plays a role in protecting the lens, and does not shade the shooting of the lens. The head end housing 30 enters the inside of the human body together with the insertion portion 2, and the lens captures an image of a lesion in the inside of the human body. The opaque body fluid or blood is inevitably adhered to the glass slide, so that an image shot by the lens is blurred, or an image of a part to be detected cannot be shot at all. At this time, the medical staff can control the operation member 1 to enable the liquid to wash the first through hole 330 through the second through hole 340 via the second channel 34, and wash away the dirt adhered to the glass slide, so that the endoscope 100 can be used normally, and the definition of the image is ensured.

The first end surface 31 of the head end housing 30 is provided with a raised area 310, and a first through hole 330 for accommodating a slide is formed in the raised area 310, and fluid washes the first through hole 330 through the second through hole 340 via the second channel 34. The first through hole 330 is arranged in the bulge area 310, and the washed cleaning water flows downwards out of the bulge area 310, so that no accumulated water is left at the first through hole 330, the problem of unclear vision at the camera is solved, and the endoscope 100 can be normally used.
