Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a visual pressure-based vascular occlusion band. Background Technology

[0002] A vascular occlusion band is a medical device primarily used to control blood flow within the surgical area during surgery to facilitate the procedure and prevent excessive bleeding.

[0003] In liver resection, to reduce intraoperative bleeding, it is sometimes necessary to block the blood flow into the liver at the porta hepatis. This is done by using a vascular occlusion band, which is usually a specially designed elastic band that can be tightly wrapped around the blood vessels to effectively and temporarily block the blood flow.

[0004] The aforementioned vascular occlusion bands, when used for vascular occlusion in the porta hepatis, cannot visually display the occlusion force, making the operation somewhat blind. During the procedure, insufficient occlusion may lead to significant bleeding, while excessive occlusion may affect the occlusion effect, making them inconvenient to use. Therefore, a vascular occlusion band with visible pressure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a visual pressure vascular occlusion band, which aims to solve the problems in the prior art where the occlusion force cannot be visually displayed during the occlusion of hepatic hilum vessels, resulting in a relatively blind operation and the possibility of insufficient occlusion leading to significant bleeding or excessive occlusion during the operation, thus affecting the occlusion effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a visual pressure vascular occlusion band, comprising an occlusion band body, a visual tube segment fixedly connected to one end of the occlusion band body, a plug fixedly connected to the other end of the visual tube segment, an observation groove formed on the outer periphery of the visual tube segment, a pressure measuring component disposed between the outer surface of the occlusion band body and the interior of the visual tube segment, a connecting thread provided in the middle section of the circumferential surface of the occlusion band body, and a connecting locking hole formed on the right side of the outer surface of the occlusion band body.

[0007] As a further description of the above technical solution:

[0008] The pressure measurement component includes a first water bladder, the outer wall of which is fixedly snapped onto the outer surface of the blocking strip body, one end of which is fixedly connected to a connecting pipe, and the other end of which is fixedly connected to a second water bladder.

[0009] As a further description of the above technical solution:

[0010] The second water bladder has a rigid transparent capsule structure, the connecting pipe has a rigid pipe material, and the first water bladder has a soft transparent capsule structure.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the second water bladder is attached to the inner wall of the visible tube section, and the outer surface of the second water bladder is provided with a measuring scale.

[0013] As a further description of the above technical solution:

[0014] The first water bladder contains a metering liquid, which extends into the second water bladder via a connecting pipe.

[0015] As a further description of the above technical solution:

[0016] The metering liquid is specifically a colored liquid.

[0017] As a further description of the above technical solution:

[0018] The observation slots are distributed in multiple circumferentially at equal intervals along the outer periphery of the visible pipe section.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the connecting thread is adapted to the inner wall size of the connecting hole.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, a pressure measuring component is used to attach and bind the blood vessels entering the liver at the porta hepatis using a first water bladder with a soft, transparent capsule structure on the outer surface of the main body of the blocking band.
