Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a measurable transparent cap. Background Art

[0002] The transparent cap is a small piece of transparent plastic that is put on the front end of the gastroscope. It is usually used to separate the mucosa and keep the lens clear. During gastroscopy, the doctor can observe the condition of the digestive tract wall through the transparent cap and maintain an appropriate field of view. In addition, the transparent cap can also be used to fix the field of view, increase the field of view space, and be used for endoscopic polypectomy, foreign body removal, endoscopic hemostasis and other operations.

[0003] During gastroscopy, there are two ways to judge the size of polyps: one is visual inspection based on the experience of medical staff; the other is to estimate the size by comparing the size of other known objects in the gastroscopy image with the polyps. Both of these methods of judging the size of polyps are not accurate enough. The size of polyps is one of the important factors in determining the treatment plan. If the error in judging the size of polyps is large, it may cause doctors to choose inappropriate treatment plans. Therefore, a measurable transparent cap is proposed to use the transparent cap to accurately judge the size of polyps. Utility Model Content

[0004] The utility model aims to solve the problem of inaccurate judgment of polyp size during gastroscopy and to provide a measurable transparent cap.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-Figure 3 The measurable transparent cap provided in this embodiment includes a sleeve 1, an annular groove 2 is provided on the inner wall of the sleeve 1 near the lower end of the sleeve 1, a reference point 3 and a plurality of measuring points 4 are provided on the annular groove 2, the reference point 3 and the plurality of measuring points 4 are unequally divided around the circumference of the annular groove 2, and the straight-line distances between the reference point 3 and each measuring point 4 are different.

[0021] The sleeve 1 is sleeved on the front end of the gastroscope for use in separating the mucosa and keeping the lens clear. When the gastroscope observes the polyp on the wall of the digestive tract, the reference point 3 on the annular groove 2 of the sleeve 1 is aligned with the edge or center of the polyp by adjusting the position of the front end of the gastroscope. The straight-line distances between several measuring points 4 on the annular groove 2 and the reference point 3 are different. One end of the polyp is located on the reference point 3. The lens position is adjusted so that the other end of the polyp is located on one of the measuring points 4. Then, the size of the polyp can be intuitively and accurately judged based on the straight-line distance between the reference point 3 and one of the measuring points 4.

[0022] Among them, the measuring points 4 include a first measuring point 4a located on the diameter of the annular groove 2, the first measuring point 4a is opposite to the reference point 3 and are respectively located at the two ends of the diameter of the annular groove 2, and the measuring points 4 also include two second measuring points 4b, a third measuring point 4c and a fourth measuring point 4d symmetrically distributed on both sides of the diameter formed by the reference point 3 and the first measuring point 4a. The several measuring points 4 are the first measuring point 4a, the second measuring point 4b, the third measuring point 4c and the fourth measuring point 4d, respectively. These measuring points are distributed on the circumference of the annular groove 2, and the straight-line distances between the reference point 2 and these measuring points 4 are different, so that the size of the polyp can be measured intuitively and accurately during gastroscopy.

[0023] Among them, the reference diameter of the annular groove 2 is formed between the reference point 3 and the first measuring point 4a, the third measuring point 4c and the fourth measuring point 4d have the same vertical distance from the reference diameter, and the vertical distance between the second measuring point 4b and the reference diameter is smaller than the vertical distance between the third measuring point 4c and the fourth measuring point 4d and the reference diameter. By using the second measuring point 4b, the third measuring point 4c and the fourth measuring point 4d at different positions, it can be ensured that these measuring points 4 are distributed at different positions on the circumference of the annular groove 2, so that different straight-line distances can be formed with the reference point 3. Different straight-line distances can be used to find the corresponding measurement segment when measuring the polyp, and then the size of the polyp can be accurately measured.

[0024] It should be noted that the straight-line distances between the reference point 3 and the first measuring point 4a, the second measuring point 4b, the third measuring point 4c and the fourth measuring point 4d are 12MM, 5MM, 7MM and 10MM respectively;

[0025] The straight-line distance between the second measuring point 4b and the third measuring point 4c on the same side of the reference diameter is 2.5MM, the straight-line distance between the third measuring point 4c and the fourth measuring point 4d on the same side of the reference diameter is 4MM, and the straight-line distance between the second measuring point 4b and the fourth measuring point 4d on the same side of the reference diameter is 6MM. Measurement segments of different lengths are formed between the reference point 3 and several measuring points 4 and the measuring point 4 itself. When a polyp is observed, it is only necessary to find the corresponding measurement segment so that the straight-line distance between the reference point 3 and one of the measuring points 4 matches the polyp diameter, and then the size of the polyp can be known based on the straight-line distance between the reference point 3 and the measuring point 4. The material of the sleeve 1 is transparent rubber and has a certain flexibility. The sleeve 1 is flattened after the gastroscope is inserted into the digestive tract. After the sleeve 1 is flattened, the reference point 3 and the first measuring point 4a form a new measurement segment, and a 5MM measurement segment will be formed between the first measuring point 4a and the fourth measuring point 4d.

[0026] Among them, the reference point 3, the first measuring point 4a, the second measuring point 4b, the third measuring point 4c and the fourth measuring point 4d are formed in different colors by coating. The reference points 3 and measuring points 4 of different colors can be easily judged during use, which facilitates the accuracy of the reference point 3, making it more convenient and quick to measure polyps according to the reference points 3 and the measuring points 4 when using the transparent cap.

[0027] Among them, a pair of mounting grooves 5 are opened on the inner wall of the sleeve 1 near the upper end of the sleeve 1, and the mounting grooves 5 are used to make the sleeve 1 of the transparent cap be sleeved and fixed on the front end of the gastroscope. The mounting grooves 5 play a limiting role, thereby improving the stability of the sleeve 1 after being sleeved on the front end of the gastroscope.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
