[0028] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-2 As shown, a transparent cap for endoscopic injection of esophageal varices is provided. The transparent cap 101 has a slot 102 on its side wall. The side wall of the slot 102 has an arc-shaped structure. The slot 102 has a U-shaped structure. The top side wall of the slot 102 has an arc-shaped chamfer.

[0030] The transparent cap 101 has a cylindrical structure, and the center line of the slot 102 is parallel to the central axis of the transparent cap 101.

[0031] The cross-sectional area of ​​the top of the transparent cap 101 is smaller than the cross-sectional area of ​​the bottom of the transparent cap 101, so that the transparent cap 101 presents an overall frustum structure.

[0032] The inner wall of the transparent cap 101 is provided with an annular reinforcing rib 104; the slot 102 intersects with the annular reinforcing rib 104, and the annular reinforcing rib 104 is provided with a slot corresponding to the slot 102.

[0033] One end of the transparent cap 101 is provided with a connector 103. The middle side wall of the connector 103 is recessed inward to form an annular groove on the side wall of the connector 103, so that the cross-section of the top and bottom of the connector 103 is larger than the cross-section of the middle part, so that the transparent cap 101 can be directly connected to the end of the gastroscope by snap-fit.

[0034] A raised ring 105 is provided on the inner wall of the connector 103 to enhance the connection between the transparent cap 101 and the tip of the endoscope.

[0035] After the transparent cap 101 is installed at the end of the gastroscope, the endoscope is inserted into the esophagus, the target vein is selected for aspiration, and the varicose vein is drawn into the slot 102, which can firmly lock the varicose vein and prevent the target injection point from moving with the patient's breathing and gastrointestinal peristalsis.

[0036] The injection needle extends from the end of the gastroscope and is inside the transparent cap 101, allowing for convenient and precise injection into the target vein under direct vision, and the injection depth can be adjusted at any time.

[0037] Using the transparent cap 101 of this application can simplify and improve the precision of surgical procedures, thereby increasing the success rate and efficacy of the surgery. At the same time, it can reduce the technical requirements of the surgeon, which is conducive to the promotion of the surgery and thus benefits more patients.

[0038] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
