Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a rapid closure device for vascular trauma in high-altitude, low-oxygen environments. Background Technology

[0002] In high-altitude areas, the significantly reduced atmospheric oxygen partial pressure (typically below sea level) poses a severe hypoxic challenge to human tissues, leading to a significant delay in tissue repair and wound healing. Vascular trauma, especially open wounds, is more difficult to close at high altitudes. Hypoxia inhibits fibroblast activity and collagen synthesis, increasing the risk of complications such as bleeding, oozing, and hematoma, thus affecting patient prognosis. For example, in high-altitude rescue or high-altitude-related surgical procedures, rapid and effective closure of vascular wall wounds is crucial for preventing blood loss and promoting recovery.

[0003] Currently, traditional vascular closure methods (such as compression hemostasis or suturing techniques) have significant shortcomings under high-altitude and low-oxygen conditions: compression hemostasis often fails to provide stable clamping, potentially leading to rebleeding; while suturing is complex, time-consuming, and easily affected by the low-oxygen environment, resulting in delayed healing. Therefore, there is an urgent need for a rapid vascular trauma closure device designed for high-altitude and low-oxygen environments. Summary of the Invention

[0004] In view of this, the present invention provides a rapid closure device for vascular trauma in high-altitude, low-oxygen environments to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid closure device for vascular trauma in high-altitude, low-oxygen environments includes: a handle, an outer tube, a middle tube, an inner tube, an inner anchor plate, a suture, and an outer anchor plate. One end of the outer tube is fixed to the handle. The inner anchor plate is disposed within the outer tube at its outlet end, and one side of the inner anchor plate has a deployable first flexible flange. The middle tube is slidably disposed inside the outer tube, with one end abutting against the inner anchor plate. A clearance groove is provided on the outer wall of the middle tube for accommodating the undeployed first flexible flange. The other end of the middle tube extends into the handle, and a perforation is provided at the other end of the middle tube. The inner tube extends into the middle tube through the perforation. The outer anchor plate is disposed within the middle tube near its outlet end, with one end of the inner tube abutting against the outer anchor plate. One end of the suture is fixed to the center of one side of the inner anchor plate, and the other end passes through the center of the outer anchor plate and extends into the inner tube. The inner anchor plate has multiple protrusions on its sidewall, and the outer anchor plate has corresponding protrusion holes. The protrusions and holes are interference-fitted for fixing and clamping the vascular wound between the inner and outer anchor plates. A middle tube drive device is located at one end of the middle tube within the handle, used to push the inner anchor plate out of the outer tube. An inner tube drive device is also located at one end of the inner tube within the handle, used to push the outer anchor plate out of the middle tube. A suture drive device is located on the handle, connected to the suture, used to pull the inner anchor plate and cause the protrusions and holes to be interference-fitted.

[0007] Furthermore, a calcium peroxide slow-release film is provided on the side of the outer anchor plate facing the inner anchor plate.

[0008] Furthermore, the outer anchor plate has a deployable second flexible flange on its periphery, which slides on the inner wall of the central tube.

[0009] Furthermore, the root of the second flexible flange bends toward the inner anchor plate.

[0010] Furthermore, it also includes an outlet vessel, which is disposed in the wall of the outer tube, with one end close to the outlet end of the outer tube and the other end extending out from the handle.

[0011] Furthermore, the central tube driving device is a central tube driving rod, the bottom end of which extends into the handle and is fixedly connected to the top wall of one end of the central tube. The handle is provided with a first sliding groove, in which the central tube driving rod is slidably connected. The top end of the central tube driving rod is provided with a first slider, which is slidably connected to the outer wall of the handle.

[0012] Furthermore, the inner tube driving device is an inner tube driving rod, the bottom end of which extends into the handle and is fixedly connected to one end of the inner tube. The handle is provided with a second sliding groove, in which the inner tube driving rod is slidably connected. The top end of the inner tube driving rod is provided with a second slider, which is slidably connected to the outer wall of the handle.

[0013] Furthermore, the suture driving device is a suture driving rod, the bottom end of which extends into the handle. The handle is provided with a third sliding groove, in which the suture driving rod is slidably connected. The top end of the suture driving rod is provided with a third slider, which is slidably connected to the outer wall of the handle. The bottom end of the suture driving rod is provided with an extension rod, and the inner tube is provided with a fourth sliding groove. The extension rod extends into the inner tube through the fourth sliding groove and is fixedly connected to the suture. The extension rod is slidably connected to the fourth sliding groove.

[0014] The beneficial effects of this invention are as follows:

[0015] After the outer tube of this invention enters the vascular wound, the inner anchor plate is pushed out of the outer tube by the middle tube. The first flexible flange of the inner anchor plate unfolds, and after unfolding, the area of ​​the first flexible flange is larger than that of the vascular wound, covering the wound from inside the blood vessel. The outer anchor plate is pushed out of the middle tube by the inner tube, and the second flexible flange on the outer anchor plate unfolds and bends towards the blood vessel. While pulling the suture, the inner tube continuously pushes the outer anchor plate, causing the outer and inner anchor plates to move towards each other, allowing the spikes to pass through the blood vessel wall and enter the spike holes, thus achieving an interference fit between the two. The inner and outer anchor plates together clamp the vascular wound, and the first and second flexible flanges together cover and facilitate the closure of the vascular wound. The calcium peroxide slow-release film on the outer anchor plate adheres to the outer wall of the blood vessel for oxygen therapy, further improving the closure efficiency in the high-altitude hypoxic environment.

The bottom end of the suture driving rod 120 is provided with an extension rod 122. The inner tube 40 is provided with a fourth sliding groove 41. The extension rod 122 extends into the inner tube 40 through the fourth sliding groove 41 and is fixedly connected to the suture 60. The extension rod 122 is slidably connected to the fourth sliding groove 41.

[0030] Working principle: Holding the handle 10, align one end of the outer tube 20 with the blood vessel wound. When the outlet end of the outer tube 20 enters the blood vessel through the wound, blood flows out from the outlet tube 90, indicating that the outlet end of the outer tube 20 has entered the blood vessel. At this time, push the first slider 101 to make the middle tube drive rod 100 slide in the first groove 11, thereby pushing the inner anchor plate 50 out of the outer tube 20. The first flexible flange 51 at the edge of the inner anchor plate 50 unfolds. After unfolding, the first flexible flange 51 is larger than the area of ​​the blood vessel wound, pulling the outer tube 20 outward. The inner anchor plate 50 and the first flexible flange 51 cover the blood vessel wound from inside the blood vessel. Push the second slider 111 to make the inner tube drive rod 110 slide in the second groove 12, thereby pushing the outer anchor plate 70 out of the middle tube 30. The second flexible flange 51 unfolds. After sliding out of the central tube 30, the outer anchor plate 70 unfolds, and its flexible flange covers the vascular wound from outside the vessel wall. Pulling the third slider 121 causes the suture drive rod 120 to slide in the third groove 13, driving the extension rod 122 to slide in the fourth groove 41, thereby pulling the suture 60 and causing the inner anchor plate 50 to move towards the vessel wall. At the same time, pushing the second slider 111 causes the inner tube 40 to push the outer anchor plate 70 towards the vessel wall. The outer anchor plate 70 and the inner anchor plate 50 move towards each other, causing the spike 52 to pass through the vessel wall and into the spike hole 71, thus achieving an interference fit. This allows the inner anchor plate 50 and the outer anchor plate 70 to jointly clamp the vascular wound. The calcium peroxide slow-release membrane 80 on the outer anchor plate 70 adheres to the outer wall of the vessel for oxygen therapy, further improving the closure efficiency in the high-altitude low-oxygen environment. Further pulling the third slider 121 and pushing the second slider 111 can pull the suture 60 out from the inner anchor plate 50.
