The transparent cap 100 helps to expand the intestinal cavity 1001, provides an anterior view, improves visibility, and facilitates treatment. The transparent cap 100 comprises a transparent cap body 10, a mounting hole 11 is formed in the cap body 10, and the mounting hole 11 penetrates through the entire cap body 10. The mounting hole 11 is used in cooperation with the digestive endoscope 1000 to enable the transparent cap 100 to be mounted on the digestive endoscope 1000. Specifically, the cap body 10 is provided with a plurality of transparent blades 20 along the circumference thereof, and a groove 22 is formed between adjacent two blades 20, so that each blade 20 can be inflated to protrude out of the cap body 10. Each blade 20 is provided with a hollow inner cavity 21, and the inner cavity 21 is connected with an inflation and deflation conduit 30. When the digestive endoscope 1000 is at the mucosal fold of the intestinal cavity 1001 and the curved portion of the intestinal cavity 1001, the inner cavity 21 of the blade 20 is inflated through the inflation and deflation conduit 30 to expand the blade 20, thereby supporting the mucosal fold of the intestinal cavity 1001 or the curved portion of the intestinal cavity 1001, so that the examination or treatment can be better performed. When the intestinal cavity 1001 is at a non-folded portion and a non-curved portion, the blade 20 can be deflated through the inflation and deflation conduit 30 to be folded on the cap body 10, thereby reducing the overall volume, so that the resistance of the transparent cap 100 moving in the intestinal tract can be reduced, and the pain of the patient during the operation process can be reduced.

[0034] Compared with the prior art, the transparent cap 100 is provided with a plurality of blades 20, each blade 20 is provided with a hollow inner cavity 21, the inner cavity 21 is inflated through the inflation and deflation pipe 30, so that the blade 20 can expand outward and further can expand the mucosa folds of the intestinal cavity 1001 and the curved part of the intestinal cavity 1001, thereby better checking and treating the mucosa folds of the intestinal cavity 1001 and the curved part of the intestinal cavity 1001, so as to avoid missing and facilitate the detection of lesions. When the transparent cap 100 passes through the mucosa folds of the intestinal cavity 1001 or the curved part of the intestinal cavity 1001, the inflation and deflation pipe 30 is deflated or inflated, so that the gas in the inner cavity 21 is discharged, so that the blade 20 is folded on the cap body 10 and does not affect the movement of the entire transparent cap 100 in the intestinal tract. It can be understood that when the intestinal cavity 1001 is not folded and not curved, the transparent cap 100 is not expanded, and the transparent cap 100 is in a folded state, so that the resistance of the transparent cap 100 moving in the intestinal tract is reduced, and the pain of the patient during operation is reduced. The transparent cap 100 of the utility model can expand outward at the mucosa folds of the intestinal cavity 1001 and the curved part of the intestinal cavity 1001, so as to better detect the mucosa folds of the intestinal cavity 1001 and the curved part of the intestinal cavity 1001, and the detection effect is better; when not folded and not curved, the blade 20 on the transparent cap 100 is folded on the cap body 10, so that the transparent cap 100 can move better in the intestinal cavity 1001, reduce the pain of the patient, and the structure is simple and reasonable.
