Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of super-fine transparent caps for endoscope, belong to the technical field of medical devices. BACKGROUND

[0002] The transparent cap for endoscope is used in the front end of endoscope, and is used for assisting to peel tissue, saves space, is easy to operate, and is applied in ultrasonic field. However, the existing transparent cap only has a socket, and the socket is connected with the head of endoscope. In a narrow space, the transparent cap is easy to fall off. In addition, when children are examined by endoscope, the local space is narrow due to disease, and the children cannot pass through, which increases the difficulty of operation. SUMMARY

[0003] The utility model provides a kind of super-fine transparent caps for endoscope, the super-fine transparent cap not only thin wall, can pass through narrow space, and upper end portion can be closely matched with the end of endoscope, not easy to fall off.

[0004] To solve the above problems, the specific technical scheme of the utility model is as follows: a kind of super-fine transparent cap for endoscope, including small diameter section, transition section and large diameter section;Small diameter section is located at the bottom, and the center is provided with an observation hole;The upper end of small diameter section is connected with transition section and large diameter section in sequence, transition section is inverted cone barrel structure, and the wall thickness is equal to that of large diameter section;The inner wall of large diameter section is attached to the outer circumference of endoscope head.

[0005] The wall thickness of the small diameter section is greater than that of the transition section and the large diameter section, and a limiting table is formed at the end of the endoscope.

[0006] The small diameter section, transition section and large diameter section are integrated structure, and the outer circumference is smoothly transitioned.

[0007] The wall thickness of the large diameter section and the transition section is provided with a water supply hole, and the inlet of the water supply hole is located at the upper end surface of the large diameter section;The outlet of the water supply hole is connected to the upper end of the inner cavity of the small diameter section.

[0008] The outer circumference of the small diameter section is provided with a tapered surface with a neck.

[0009] The super-fine transparent cap for endoscope of the present application has the following advantages by adopting the above structure:

[0010] 1, the taper structure of large upper end and small lower end can reduce the volume of the transparent cap as a whole, the front end is narrower, which is easy to enter narrow space, and the transparent cap can enter narrow space such as small digestive tract of infants and children or narrow digestive tract caused by disease more smoothly, and the probability of mucosal damage is lower;The rear end can better wrap the endoscope, and can better overcome the risk of falling off caused by accumulation;

[0011] 2. The wall thickness of the small diameter section is greater than that of the transition section, which not only improves the strength of the front end, but also forms a limiting stage in the inner cavity. This has three advantages: first, it makes it easier to assemble the endoscope into the designated position; second, the inner surface above the limiting stage forms a vacuum surface with the endoscope, which better wraps the endoscope and prevents it from falling off; and third, because the inner diameter of the limiting stage is recessed inward, the outer diameter of the outer wall is smaller for the same wall thickness, which reduces the maximum outer diameter of the product as a whole, making it easier for it to pass through the digestive tract during use.

[0012] 3. The ultra-fine transparent cap has a water inlet, which does not occupy the forceps channel. During examination or surgery, the lens may be covered with mucus, blood and surgical smoke. At this time, the water sprayed from the water inlet will clear the lens residue and restore the image to a clear state. It is convenient to operate and does not require repeated switching with other instruments, making it more efficient and convenient. Attached Figure Description

[0016] Figure 4 A stereoscopic view of the application of an ultra-fine transparent cap for an endoscope. Detailed Implementation

[0017] like Figure 1 and Figure 2 As shown, an ultra-fine transparent cap for an endoscope includes an integral structure consisting of a small-diameter section 1, a transition section 2, and a large-diameter section 3 connected in sequence, with a smooth transition on the outer circumference; the small-diameter section 1 is located at the bottom and has an observation hole 4 in the center; the upper end of the small-diameter section 1 is connected to the transition section 2 and the large-diameter section 3 in sequence, the transition section 2 is an inverted conical structure and its wall thickness is equal to that of the large-diameter section 3; the inner wall of the large-diameter section 3 fits against the outer circumference of the endoscope lens.

[0018] The wall thickness of the small-diameter segment 1 is greater than that of the transition segment 2 and the large-diameter segment 3, and a limiting stage 5 is formed at the endoscope lens section. Figure 3 and Figure 4 As shown, the limiting stage 5 facilitates the assembly of the endoscope to the designated position, and the inner wall of the large-diameter section 3 is mirror-polished, forming a vacuum surface between the endoscope and the inner wall of the large-diameter section 3, which better encloses the endoscope and prevents it from falling off.

[0019] Water inlet holes 6 are provided within the wall thickness of the large-diameter section 3 and the transition section 2. The inlet of the water inlet hole 6 is located on the upper end face of the large-diameter section 3; the outlet of the water inlet hole 6 leads to the upper end of the inner cavity of the small-diameter section 1. Figure 3 andFigure 4 As shown, during endoscopy or surgery, the mirror surface will be attached with mucus, blood and smoke generated by surgery, at this time the water sprayed from the water hole will make the image clear, and the operation is convenient.

[0020] The outer circumference of the small diameter section 1 is provided with a tapered surface 7 with a neck, so that the lower end wall of the small diameter section 1 is thinner, which is convenient for endoscopy, not only more smooth into narrow space, but also better drilling into the bottom of the tissue when cutting larger tissue, and more convenient and faster stripping.
