Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In the present invention, "end" refers to the end close to the focal tissue during the operation, "front" refers to the direction away from the focal tissue during the operation, and "rear" refers to the direction close to the focal tissue during the operation.

As shown in fig. 1 to 3, the present invention provides a transparent cap for an endoscope, comprising a main body 4 and a protection ring 5, wherein the main body 4 is of a tubular structure and made of transparent or semitransparent material, the main body 4 can be a straight tube with equal diameter or a reducer tube, the main body 4 is made of soft material, usually made of PTFE or PVC pipe material, and is easily embedded by a spine portion 2 of a surgical instrument 1, and the protection ring 5 is made of hard material, is not embedded by the spine portion 2 of the surgical instrument 1, and is preferably made of hard metal; one end of the main body 4 is a socket section 401 suitable for externally sleeving the surgical instrument 1, namely, the socket section 401 is a straight pipe section with the same diameter, the outer diameter of the socket section 401 is slightly smaller than the inner diameter of the surgical instrument 1, when in use, the surgical instrument 1 is sleeved outside the socket section 401, the protection ring 5 is arranged close to the tail end of the socket section 401, the protection ring 5 is arranged outside the main body 4, namely, the protection ring 5 is arranged at one end close to the focal tissue, so that the protection ring 5 and the sharp thorn part 2 of the surgical instrument 1 are approximately the same in height (the sharp thorn part 2 is also arranged on the surgical instrument 1 close to the focal tissue), the protection ring 5 is directly opposite to the surgical instrument 1, when the surgical instrument 1 is not separated from the socket section 401, the sharp thorn part 2 extends along the axial direction, when the surgical instrument 1 is operated so as to be separated from the socket section 401, the sharp thorn part 2 shrinks towards, therefore, the protection ring 5 is directed to the surface of the protection ring 5, because the protection ring 5 is made of hard material, the spine part 2 can slide on the outer surface of the protection ring 5, the arrangement of the protection ring 5 close to the end of the socket joint section 401 means that the distance between the protection ring 5 and the end of the socket joint section 401 is very small, usually within 0.5mm, the spine part can also be directly connected to the end of the socket joint section 401, and the spine part 2 can be separated from the transparent cap instantly after leaving the protection ring 5.

Taking an example of a commonly-used surgical instrument 1, namely an anastomosis clip, the front end of the anastomosis clip is a spine portion 2, and the width of the protection ring 5 is set according to the size of the spine portion 2 and the distance from the tail end of the sleeve section 401, so as to ensure that the spine portion 2 points to the surface of the protection ring 5 when contracting, preferably, the width of the protection ring 5 is 1-3 mm.

The protective ring 5 may be directly fixed to the end of the socket 401 by means of an adhesive, and in order to facilitate the rapid release of the anastomosis clip, referring to fig. 4, according to another embodiment of the present solution, the protective ring 5 may be provided in a tapered configuration with an outer diameter decreasing from front to back.

In one embodiment of the present invention, as shown in fig. 2, the end of the socket joint section 401 is provided with a chamfer 4011, the outside of the socket joint section 401 located in front of the chamfer 4011 is provided with an annular groove 4012 suitable for installing the protection ring 5, the width of the protection ring 5 is 1mm, the width of the annular groove 4012 is slightly larger than 1mm, and the width of the chamfer 4011 (i.e. the dimension along the axial direction of the socket joint section 401) is 0.5 mm. The chamfer 4011 reduces the diameter of the portion of the female portion 401 located behind the protective ring 5, so that the spike 2 does not sink into the end of the female portion 401 at the instant when the anastomosis clip 1 is detached from the female portion 401. The protection ring 5 can be pasted in the annular groove 4012, the protection ring 5 can be clamped in the annular groove 4012 in an interference connection mode, and the installation of the protection ring 5 is facilitated due to the chamfer 4011 of the sleeving connection section 401. In order to facilitate the rapid release of the anastomosis clip, the protection ring 5 may also be provided with a tapered configuration with a decreasing outer diameter from front to back.

In another embodiment of the present invention, the main body 4 further has a limiting section 402 connected to the socket section 401, and the outer diameter of the limiting section 402 is larger than the outer diameter of the socket section 401. As shown in fig. 1 and 2, the main body 4 is of an integral structure, the outer diameters of the upper part and the lower part of the main body 4 are smaller, the outer diameter of the middle part is larger, and the limiting section 402 is used for limiting the axial position of the anastomosis clip 1, so that the spine 2 and the protection ring 5 are as level as possible, and the spine 2 is prevented from pointing to the area of the main body 4 when being contracted.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "inner", "outer", "axial", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In this specification, the schematic representations of the terms are not necessarily referring to the same embodiment. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention.
