[0041] According to some embodiments of this application, please refer to Figures 1 to 5 This embodiment relates to a vascular stump protective sleeve, including a vascular clamp 1 and a protective bag 2. The vascular clamp 1 includes an upper clamp arm 11, a connecting portion 12 and a lower clamp arm 13. The upper clamp arm 11 is connected to the lower clamp arm 13 through the connecting portion 12. The connecting portion 12 is provided with an adjustment hole 14. The upper clamp arm 11 is provided with a locking hook portion, and the lower clamp arm 13 is provided with a fixing portion, which is used to cooperate with the locking hook portion; the protective bag 2 is provided with an opening 21, which is connected to the vascular clamp 1. When the vascular clamp 1 is clamped on the vascular stump 3, the vascular clamp 1 closes the opening 21 of the protective bag 2.

[0042] Blood vessels include arteries and veins. The blood vessel stump protective sleeve involved in this embodiment can be applied to arterial stumps and venous stumps.

[0043] In this embodiment, the blood vessel stump 3 is in a state of blocked blood flow; the principles of the locking hook portion, the fixing portion and the adjustment hole 14 are conventional technical means and will not be described again here.

[0044] In this embodiment, the vascular clamp 1 also includes two upper clamping shafts located on the upper clamping arm 11 and two lower clamping bodies located on the lower clamping arm 13. The two upper clamping shafts and the two lower clamping bodies are used to clamp on the clamp. After the vascular clamp 1 clamps the vascular stump 3, it will automatically detach from the clamp. The specific structural principles of the vascular clamp 1 and the clamp are conventional technical means, and the specific operating procedures and principles will not be repeated here.

[0045] In this embodiment, the bottom of the protective bag 2 is an elliptical structure or a V-shaped structure. The protective bag 2 must be sealed when in use. The protective bag 2 protects the vascular stump 3 to prevent the vascular stump 3 from being corroded by pancreatic juice, digestive tract fluid, etc. The specific principle of the protective bag 2 is a conventional technical means and will not be repeated here.

[0046] In this embodiment, the protection bag 2 is mainly fixed on the vascular clamp 1 so that the vascular clamp 1 and the protection bag 2 can be used together without having to perform the operation in two steps.

[0047] As an embodiment of the present invention, Figure 4 As shown, the opening 21 includes a first connecting section 211 and a second connecting section 212. One end of the first connecting section 211 is connected to the lower clamping arm 13, the other end of the first connecting section 211 is connected to one end of the second connecting section 212, and the other end of the second connecting section 212 is connected to the upper clamping arm 11.

[0048] In this embodiment, one end of the first connecting section 211 is connected to the inner wall of the lower clamping arm 13 , and the other end of the second connecting section 212 is connected to the inner wall of the upper clamping arm 11 .

[0049] In this embodiment, the left side of the opening 21 is formed by a first connecting section 211 and a second connecting section 212, and the right side of the opening 21 is respectively connected and fixed to the first clamping surface 111 of the upper clamping arm 11 and the second clamping surface 131 of the lower clamping arm 13. This facilitates the vascular clamp 1 to clamp the opening 21.

[0050] As one embodiment of the present invention, the cross-sectional shape of the connection between the first connecting segment 211 and the second connecting segment 212 is V-shaped. Thus, the cross-sectional shape of the connection between the first connecting segment 211 and the second connecting segment 212 is V-shaped, and after the vascular clamp 1 is clamped, the first connecting segment 211 and the second connecting segment 212 are closed.

[0051] In one embodiment of the present invention, the second connecting section 212 is a soft edge, and the length of the first connecting section 211 is equal to the extended length of the second connecting section 212. Thus, by virtue of the second connecting section 212 being a soft edge, after the vascular clamp 1 is tightened, the first connecting section 211 moves toward the inner wall of the lower clamp arm 13, while the second connecting section 212 is straightened, thereby resolving the sealing problem of the opening 21 and sealing the protective bag 2 to prevent leakage from the opening 21.

[0052] In other embodiments, the first connecting section 211 can be thickened to make the first connecting section 211 harder, so as to facilitate forming the opening 21 into a V-shaped structure; or the structure of the first connecting section 211 remains unchanged, so that the second clamping surface 131 of the lower clamping arm 13 has an additional thin arm facing the direction of the opening 21, and the first connecting section 211 of the opening 21 is fixed by the thin arm, so as to facilitate the vascular clamp 1 to seal the opening 21.

[0053] As one embodiment of the present invention, the inner wall of the upper clamping arm 11 is provided with a first clamping surface 111, and the inner wall of the lower clamping arm 13 is provided with a second clamping surface 131. The top of the protective bag 2 is respectively connected to the first clamping surface 111 and the second clamping surface 131. This facilitates the upper clamping arm 11 and the lower clamping arm 13 to clamp the top of the protective bag 2.

[0054] As an embodiment of the present invention, the top of the opening 21 of the protective bag 2 is respectively connected to the first clamping surface 111 and the second clamping surface 131. In this way, the top of the opening 21 of the protective bag 2 is conveniently connected to the first clamping surface 111, the second clamping surface 131 and 211.

[0055] As an embodiment of the present invention, Figure 3 and Figure 5 As shown, the top of the opening 21 of the protective bag 2 protrudes from the vascular clamp 1. The top of the opening 21 of the protective bag 2 protrudes from the vascular clamp 1 by 2-3 mm. Too much is not conducive to clinical use. In this way, the sealing of the protective bag 2 can be ensured, and the protective bag 2 and the vascular clamp 1 are not easy to fall off.

[0056] In one embodiment of the present invention, the protective bag 2 is made of a transparent material. During use, the protective bag 2 is placed over the vascular stump 3, allowing the vascular clip 1 to pass through the protective bag 2 and be precisely clamped on the vascular stump 3. While the vascular clip 1 is made of a hard plastic material with some toughness, the protective bag 2 is thinner and more flexible overall, not as hard as the clip itself.

[0057] As an embodiment of the present invention, the vascular stump protective sleeve is made of absorbable or non-absorbable material. In this embodiment, the protective bag 2 can be made of polyurethane, and the vascular clamp 1 can also be made of non-absorbable material, both of which are within the scope of protection of this embodiment.

[0058] As an embodiment of the present invention, the vascular clamp 1 and the protective bag 2 are integrally formed. Thus, the vascular clamp 1 and the protective bag 2 are integrally formed, which facilitates the production of the vascular clamp 1 and the protective bag 2.

[0059] Different from the prior art, the technical solution of the present application is to provide an opening 21 on the protective bag 2, and the opening 21 is connected to the vascular clamp 1. When the vascular clamp 1 is clamped on the vascular stump 3, the vascular clamp 1 closes the opening 21 of the protective bag 2. During use, by providing the protective bag 2 on the vascular clamp 1, the vascular clamp 1 is clamped on the vascular stump 3 by the clamp applier, and the vascular stump 3 is protected by the protective bag 2 to prevent the vascular stump 3 from being corroded by pancreatic juice, digestive tract fluid, etc. In this way, there is no need to divide it into two steps, and only one step is needed to protect the vascular stump 3. The steps are simple and easy to use.
