[0005] Further, the second end of the connecting part is provided with a rotating ring, the connecting end of the protection part and the connecting part is provided with an annular groove matched with the rotating ring, and the rotating ring and the annular groove have corresponding rotating damping therebetween.

[0006] Further, the surrounding part is coaxial with the protection part and has a corresponding operation length along the central axis direction.

[0007] Further, the inner wall of the rotating end of the sleeve is provided with an internal thread, and the outer wall of the connecting part is provided with an external thread matched with the rotating end of the sleeve.

[0008] With the above structure, the endoscope inclined transparent cap has the beneficial effects as follows: the endoscope inclined transparent cap has the inclined cutout at the front end of the transparent cap, increases the operation space and the field of view, and facilitates the separation of the foreign matter and the esophageal wall; when the foreign matter is taken out, the inclined surface of the front end of the transparent cap pushes the foreign matter to penetrate into the esophageal wall, and the foreign matter is fixed by the foreign matter forceps, so that a reverse relative movement is generated, and the foreign matter is easily separated from the pipe wall, thereby reducing the risk of bleeding and perforation. In addition, the sleeve is arranged, the size of the inclined cutout can be adjusted according to the actual requirement of taking out the foreign matter when the transparent cap is installed, the operation space is ensured, and the exposed area of the foreign matter when entering the transparent cap after being taken out can be reduced, the foreign matter and the esophageal wall are separated by the enclosing part, and the enclosing part plays a protection role when the foreign matter is taken out.

[0014] The technical scheme in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments; based on the embodiments in the present application, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the present application.

[0015] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0016] like Figs. 1-3 As shown, an endoscope with a slanted transparent cap includes a connecting part and a protective part that are interconnected. The connecting part and the protective part are tubular structures with open ends and are coaxial. The connection is a damped rotational connection. Specifically, the two ends of the connecting part along the axial direction are open, and the first end is adapted to the front end of the endoscope. The two ends of the protective part along the axial direction are also open, and are damped rotationally connected to and communicate with the second end of the connecting part. The protective part has a predetermined axial working length and a radial working length. The protective part has a slanted cut along the axial direction towards the front end. The slanted cut has a predetermined tilt angle and is larger than a normal circular opening, increasing the field of vision and operating space, facilitating various retrieval operations. The transparent cap is made of transparent material, and the first end of the connecting part has corresponding elastic deformation capability, which can stably cover the front end of the endoscope.

[0017] The connecting part has a rotating ring at its second end, and the connecting end of the protective part has an annular groove that matches the rotating ring. The rotating ring and the annular groove provide corresponding rotational damping. During installation, the connecting part covers the front end of the endoscope, and the transparent cap is assembled onto the front end of the endoscope, providing a clear field of view and operating space for the lens. After installation, the protective part can be rotated to adjust the direction of the oblique incision for tube insertion. When removing foreign objects, the oblique surface at the front end of the transparent cap pushes forward against the esophageal wall at the insertion point of the foreign object, while simultaneously using foreign body forceps to fix the foreign object. This creates a relative movement in the opposite direction, making it easier for the foreign object to dislodge from the esophageal wall, reducing the risk of bleeding and perforation.

[0018] In some preferred embodiments, a sleeve is disposed on the outer side of the connecting part and the protective part. The sleeve has a rotating end adapted to the thread of the connecting part and a retaining part that can cover the outside of the protective part. The retaining part is coaxial with the protective part and has a corresponding working length along the central axis. The inner wall of the rotating end of the sleeve is provided with an internal thread, and the outer wall of the connecting part is provided with an external thread adapted to the rotating end of the sleeve for a predetermined length. After installation, the sleeve can be rotated and moved axially. The sleeve can move from the rear end of the oblique cut to the front end and close the oblique cut for a corresponding length, while retaining the corresponding cut length.

[0019] Specific use as follows: in use, the connecting part covers the front end of the endoscope to install the transparent cap, before the tube is inserted, the protection part is rotated to adjust the angle of the oblique cut, when the foreign matter is taken out, the forceps body can be stretched out from the instrument outlet channel of the endoscope, the oblique cut can provide more operation space, which is convenient for the operation of taking out the foreign matter (convenient for the foreign matter to separate from the esophageal wall), the front end of the oblique opening of the protection part pushes the esophageal wall of the foreign matter piercing end forward, and the foreign matter is fixed by the foreign matter forceps at the same time, so that a reverse relative movement is generated, the foreign matter is easy to fall off from the tube wall, and the risk of bleeding and perforation is reduced.

[0020] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents. In general, if a person skilled in the art is inspired by it, without departing from the purpose of the present application, similar structure and embodiments can be designed without creative design, which should belong to the protection scope of the present application. The components of the present application can be driven by corresponding external motors, which are prior art and will not be described here.
