Description

intraluminal vascular drainage device

technical field

The invention relates to the field of connecting pipes specially suitable for medical use, in particular to an intraluminal blood vessel diversion device.

Background technique

Arterial atherosclerosis occurs, and the sclerotic plaque can gradually thicken the blood vessel wall, causing lumen stenosis and occlusion, causing intermittent claudication, rest pain and other limb ischemia manifestations. In order to treat this condition, the commonly used surgical treatment method is to use artificial blood vessels or autologous veins to do vascular bypass, and the blood from the proximal end of the arterial occlusion is introduced into the distal end through a bypass tube, which can relieve the symptoms of ischemia.

When doing vascular bypass, it is necessary to use vascular occlusion forceps to clamp the proximal and distal blood vessels at the occlusion of the artery to block the blood flow of the surgical blood vessels, and then perform bypass surgery. This not only blocks the blood supply of the distal limbs of the blood vessels, but also because the blood vessels with atherosclerosis are relatively fragile, when the blood vessel blocking forceps are used, a little bit will lead to the rupture of the blood vessels, so the operation risk is higher. .

FIG. 2 is a schematic structural diagram of Embodiment 2 of the present invention.

Detailed ways

The present invention will be further described below with reference to the embodiments and accompanying drawings.

Embodiment 1. The intraluminal vascular diversion device as shown in FIG. 1 includes an inflation balloon. The inflation balloon includes a balloon 1 and a catheter 2. The balloon 1 is provided with a blood channel 3. One end of the balloon 1 extends to the other end.

Specifically, the inflation balloon is the same as the existing inflation balloon for vascular dilation. When in use, the balloon 1 can be sent to the bypass incision at the proximal end of the arterial occlusion through the catheter 2, and then passed through the catheter 2. Gas or liquid can be injected into the balloon 1, so that the balloon 1 is inflated and adhered to the blood vessel wall.

In this way, the blood in the blood vessel can only flow through the blood channel 3 on the balloon 1, and no blood will flow out of the blood vessel where the bypass incision is cut. Bypass surgery can be performed without blocking blood flow in the blood vessel. Moreover, the inflated balloon 1 will not exert pressure on the blood vessel, so that it is not easy to cause damage to the blood vessel, and the operation risk is reduced.

In this embodiment, preferably, the catheter 2 passes through the balloon 1 along the blood channel 3 and communicates with the balloon 1 . In this way, the blood channel 3 with a larger diameter can be set to pass more blood and meet the blood supply demand. At the same time, in order to reduce the resistance of the blood channel 3 to blood flow, the catheter 2 communicates with the balloon 1 through a communication tube 4 . The communication tube 4 is arranged in the blood channel 3, and its two ends are respectively connected with the catheter 2 and the balloon 1. The communication tube 4 plays the role of fixedly connecting the catheter 2 and the balloon 1, and the gas or liquid in the catheter 2 can be Enter the balloon 1 along the communication tube 4 to inflate the balloon 1 to fit the vessel wall.

The end of the catheter 2 is provided with a marking device 5 for surgical positioning. The marking device 5 can mark the position of the end of the catheter 2 during the operation, so as to determine the position of the balloon 1, so that the doctor can accurately send the balloon 1 to the bypass incision. place. The marking device 5 may be an electromagnetic sensor, so that the position of the distal end of the catheter 2 can be tracked using existing electromagnetic surgical navigation systems.

Moreover, in order to facilitate the delivery of the balloon 1 to the bypass incision in the early stage of the operation, the communicating tube 4 is a flexible tube, so that before gas or liquid is injected through the catheter 2, the communicating tube 4 can be attached to the catheter 2 to shrink the entire The volume of balloon 1. By injecting gas or liquid through the catheter 2 , the communication tube 4 can be expanded to form a channel, so as to inject the gas or liquid into the balloon 1 .

The outer wall of the balloon 1 is provided with an incision positioning groove 6. After the balloon 1 is sent to the bypass incision, the surgeon can touch the blood vessels at the bypass incision with his fingers, and an obvious depression can be felt at the incision positioning groove 6. to determine the location of the bypass incision. Moreover, due to the existence of the incision positioning groove 6, there is a space margin between the blood vessel wall at the bridge incision and the outer surface of the balloon 1. This space margin is the space for the scalpel to flow out, so as to prevent the surgeon from cutting the blood vessel when cutting the blood vessel. Balloon 1, reducing surgical risk.

Embodiment 2. As shown in the figure, Embodiment 2 is roughly the same as Embodiment 1. The main difference is that: the balloon 1 is provided with a plurality of blood channels 3, and all blood channels 3 are evenly distributed around the catheter 2. . After the balloon 1 is inflated and adhered to the blood vessel wall, blood can only flow through the several blood channels 3, so that bypass surgery can be performed without blocking the blood circulation in the blood vessel.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those of ordinary skill in the art can make a variety of similar It is indicated that such transformations fall within the protection scope of the present invention.
