A slanted transparent cap for endoscopes

Abstract

This invention provides a beveled transparent cap for endoscopes, comprising a connecting part and an operating part. The connecting part is detachably connected to the endoscope, allowing the transparent cap to be easily and securely mounted on the endoscope. The operating part is a hollow frustum-shaped structure with openings at both ends. The inner diameter of the operating part gradually decreases from the end furthest from the endoscope to the end closest to the endoscope, and the inner diameter of the operating part at the opening end near the endoscope is larger than the outer diameter of the endoscope. This results in a larger opening at the front end of the transparent cap, facilitating the wrapping and grasping of larger foreign objects or specimens. The beveled end face of the operating part, furthest from the endoscope, not only effectively widens the surgical field of view and reduces obstruction of the field of view by the front end of the operating part, but also allows the front end of the transparent cap to be closer to the lesion, facilitating various operations. A friction-resistant anti-slip structure is provided on the beveled surface, which increases the friction between the transparent cap and the foreign object when grasping it, further improving the stability of the transparent cap during operation.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a slanted transparent cap for endoscopes. Background Technology

[0002] In gastrointestinal endoscopy, the transparent cap serves as an important auxiliary tool, mainly playing a role in stabilizing lesions, securing the field of vision, and facilitating precise operations.

[0003] The applicant has discovered that the prior art has at least the following technical problems: Most existing transparent caps are cylindrical in shape with a flat front end. This design inevitably obstructs part of the surgical field of vision during surgery, affecting the surgeon's observation and operation. Moreover, the flat front end makes it difficult to effectively grasp larger foreign objects or specimens, increasing the difficulty of the procedure.

[0004] Furthermore, application number CN201922064837.3 discloses a transparent cap and endoscope used in conjunction with an endoscope. Although the front part of the transparent cap has a partially circular cross-section capable of cutting tissue, thus expanding the surgical field of view and providing some cutting function to a certain extent, when it is necessary to remove larger foreign bodies or specimens, the blade-like surface at the front of the transparent cap is too sharp to effectively grasp the foreign body, increasing the difficulty and risk of the surgery.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0006] The purpose of this invention is to provide a slanted transparent cap for endoscopes, addressing the design flaws of existing transparent caps that lack effective gripping and friction-enhancing structures, making it difficult to effectively grasp larger foreign objects or specimens. The preferred technical solutions provided by this invention offer numerous technical benefits, which are detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a beveled transparent cap for endoscopes, comprising a connecting part and an operating part connected in sequence. The connecting part is detachably connected to the endoscope. The operating part is a hollow frustum shape with openings at both ends. The inner diameter of the operating part gradually decreases from the end away from the endoscope to the end closer to the endoscope, and the inner diameter of the opening end of the operating part closer to the endoscope is larger than the outer diameter of the endoscope. The opening end face of the operating part away from the endoscope is a beveled surface, and a friction anti-slip structure is provided on the beveled surface.

[0008] Preferably, the friction anti-slip structure includes a plurality of dot-shaped depressions disposed on the inclined surface.

[0009] Preferably, the friction anti-slip structure includes a plurality of mesh-like recesses disposed on the beveled surface.

[0010] Preferably, the connecting part has a connecting groove, the inner wall of the connecting groove has an internal thread section, and the outer wall of the endoscope has an external thread section that matches the internal thread section.

[0011] Preferably, it further includes a nylon ring sheet, which is embedded in the inner wall of the connecting groove, and the internal thread section and the nylon ring sheet are arranged sequentially in a direction from near the operating part to away from the operating part.

[0012] Preferably, the cross-section of the connecting portion is a regular hexagon.

[0013] Preferably, the angle between the front end of the beveled surface and the longer side wall of the operating part is 10° to 55°.

[0014] The preferred technical solution of this utility model can also produce at least the following technical effects: This invention effectively avoids the technical problems of existing transparent caps, which have design defects, lack effective gripping and friction-increasing structures, and are difficult to effectively grip larger foreign objects or specimens.

[0015] This utility model provides a beveled transparent cap for endoscopes, including a connecting part and an operating part connected in sequence. The connecting part is detachably connected to the endoscope. The operating part is a hollow frustum shape with openings at both ends. The inner diameter of the operating part gradually decreases from the end away from the endoscope to the end closer to the endoscope. The inner diameter of the operating part at the opening end closer to the endoscope is larger than the outer diameter of the endoscope. The opening end face of the operating part away from the endoscope is a beveled surface, and a friction anti-slip structure is provided on the beveled surface.

[0016] This utility model discloses a transparent cap comprising a connecting part and an operating part. The connecting part is detachably connected to the endoscope, allowing the transparent cap to be conveniently and securely installed on the endoscope. The operating part has a trumpet-shaped design, giving the transparent cap a larger opening at the front end, facilitating the wrapping and grasping of larger foreign objects or specimens. Simultaneously, the opening face of the operating part away from the endoscope is beveled, effectively widening the surgical field of view and reducing obstruction of the field of view by the front end of the operating part. It also allows the front end of the transparent cap to be closer to the lesion, facilitating various operations. Furthermore, the friction-resistant anti-slip structure on the beveled surface increases the friction between the transparent cap and the foreign object when grasping it, further improving the stability of the transparent cap during operation.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: like Figures 1-3 As shown, this utility model provides a beveled transparent cap for an endoscope, including a connecting part 1 and an operating part 2 connected in sequence. The connecting part 1 is detachably connected to the endoscope. The operating part 2 is a hollow frustum-shaped structure with openings at both ends. The inner diameter of the operating part 2 gradually decreases from the end away from the endoscope to the end closer to the endoscope, and the inner diameter of the operating part 2 at the opening end closer to the endoscope is larger than the outer diameter of the endoscope. The opening end face of the operating part 2 away from the endoscope is a beveled surface 21, and a friction anti-slip structure is provided on the beveled surface 21.

[0022] Furthermore, the angle between the front end of the oblique surface 21 and the longer side wall of the operating part 2 is 30°.

[0023] The connecting part 1 is detachably connected to the endoscope, which facilitates the installation and removal of the transparent cap and improves the flexibility of use.

[0024] The trumpet-shaped design of the operating section 2 allows for a larger opening at the front of the transparent cap, facilitating the smoother entry of foreign objects or specimens into the operating section 2. Furthermore, the tapering inner diameter acts as a guide during entry, causing the foreign object or specimen to gradually move along the inner wall of the operating section 2 towards the endoscope. Simultaneously, it provides some restraint on the foreign object or specimen, making it easier to grasp larger objects or specimens into the operating section 2, thus improving retrieval efficiency.

[0025] The inner diameter of the operating part 2 near the opening of the endoscope is larger than the outer diameter of the endoscope, so it will not interfere with the endoscope.

[0026] Compared to the flat end face, the opening end face of the operating part 2 in this embodiment, which is away from the endoscope, is a beveled surface 21. This not only expands the operating field of view to a certain extent, but also changes the contact angle and method with foreign objects, so that the front end of the transparent cap can be closer to the lesion, making it easier to perform various operations.

[0027] The connection between the oblique surface 21 and the operating part 2 is smoothly transitioned.

[0028] In addition, the friction-resistant anti-slip structure on the beveled surface 21 can increase the friction between the object and the specimen when grasping it, further improving the stability of the transparent cap during operation.

[0029] It should be noted that the angle between the front end of the oblique surface 21 and the longer side wall of the operating part 2 can be flexibly set according to the usage requirements.

[0030] As an optional implementation, the friction anti-slip structure includes a plurality of dot-shaped recesses 22 disposed on the chamfered surface 21.

[0031] The design of the dotted indentations 22 makes the oblique cut surface 21 have an uneven structure, which increases the friction to a certain extent when the oblique cut surface 21 comes into contact with the foreign object, reduces the relative sliding between the transparent cap and the foreign object, and improves the stability of operation.

[0032] The dotted depression 22 and the oblique cut surface 21 have a smooth transition.

[0033] As an optional implementation, the connecting part 1 is provided with a connecting groove 11, and an internal thread section 13 is provided on the inner wall surface of the connecting groove 11, and an external thread section adapted to the internal thread section 13 is provided on the outer wall surface of the endoscope.

[0034] The connecting part 1 is securely connected to the endoscope by the screw engagement between the external thread section on the outer wall of the endoscope and the internal thread section 13 on the inner wall of the connecting groove 11.

[0035] As an optional implementation, it also includes a nylon ring 14, which is embedded in the inner wall of the connecting groove 11, and the internal thread section 13 and the nylon ring 14 are arranged sequentially in the direction from near the operating part 2 to away from the operating part 2.

[0036] Furthermore, a positioning groove 12 is provided at one end of the connecting groove 11 near the operating part 2 for installing the nylon ring 14. The nylon ring 14 is made of nylon material.

[0037] During the screwing process, the nylon ring 14 will come into contact with and be compressed against the external thread section of the endoscope's outer wall. Since the nylon ring 14 is made of nylon material, which has a certain elasticity and coefficient of friction, the nylon ring 14 will exert a certain pressure on the endoscope. The friction generated by this pressure will hinder the relative rotation between the endoscope and the connecting part 1, thereby achieving a self-locking effect and preventing the connecting part 1 and the endoscope from loosening due to external forces or other factors during the operation.

[0038] As an optional implementation, the cross-section of the connecting part 1 is a regular hexagon.

[0039] This design allows for quick and accurate placement of auxiliary tools such as open-end wrenches onto the connecting part 1, thus facilitating the assembly and disassembly of the connecting part 1 and the endoscope.

[0040] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 4 As shown, the friction anti-slip structure includes multiple mesh-like recesses 23 disposed on the oblique surface 21.

[0041] The design of the mesh recess 23 makes the oblique surface 21 have an uneven structure, which increases the friction to a certain extent when the oblique surface 21 comes into contact with the foreign object, reduces the relative sliding between the transparent cap and the foreign object, and improves the stability of operation.

[0042] The mesh-like depression 23 and the oblique cut surface 21 have a smooth transition.

[0043] As an optional implementation, the angle between the front end of the beveled surface 21 and the longer side wall of the operating part 2 is 20°. This configuration further expands the operating field of view.
