Description

A double balloon catheter with a pigtail

technical field

The invention relates to the technical field of medical devices, in particular to a double-balloon catheter with a pigtail tube.

Background technique

At present, in the field of vascular surgery, endovascular treatment is almost the mainstream method for treating various vascular diseases. It has the advantages of less trauma and shorter hospital stay. Among them, aortic disease is one of the diseases with high risk and difficult treatment technology in the field of vascular surgery. First, due to the large diameter and high pressure of the aortoiliac artery itself, once it ruptures, the mortality rate is extremely high, which is also a great challenge for vascular surgeons. The key to the treatment of aortic rupture is to shorten the bleeding time and reduce the amount of bleeding as much as possible to save the patient's life. At present, in the treatment of ruptured aorta, for patients with hemodynamic instability, a balloon is placed in the proximal aortic cavity to block the blood flow of the aorta, and then open or endovascular surgery is performed in order to reduce the amount of bleeding. Before placing the balloon, it is necessary to perform radiography to understand the shape of the blood vessel and the location of the breach. This process takes a long time. At the same time, the balloon is placed in an invisible situation. The placement of the balloon is inaccurate and the adjustment of the balloon takes a long time. Lead to longer bleeding time, larger amount of bleeding, resulting in higher mortality of such patients.

Contents of the invention

The purpose of the present invention is to provide a double-balloon catheter with a pigtail tube to solve the problem of long time required for angiography and balloon placement when treating ruptured aorta.

The technical scheme that the present invention solves the problems of the technologies described above is as follows:

In the present invention, the pigtail tube and the balloon assembly are integrated, and the pigtail tube is inserted into the aorta for radiography, then the first balloon assembly and the second balloon assembly enter the aorta, and the first balloon assembly bypasses the wound site. After stretching, the blood is obstructed to limit the flow of blood. At this time, the second balloon component is located at the wound, and the second balloon component is stretched to compress and stop bleeding. Through the radiography function of the pigtail tube, the location of the wound can be accurately found, and the second balloon assembly can be accurately placed at the location of the wound without taking out the pig ureter, thereby shortening the time required for radiography and balloon placement. Due to the blocking effect of the first balloon component, the bleeding time can be shortened and the amount of bleeding can be reduced.

Further, the above-mentioned first balloon assembly includes a first balloon and a first conduit; a pigtail tube passes through the first balloon and is sealedly connected with the first balloon; one end of the first conduit communicates with the first balloon, and the first The other end of the conduit is close to the operating end, and the middle part of the first conduit is connected with the outer wall of the pigtail.

The pigtail tube of the present invention passes through the first balloon, and the first balloon is centered so that the blood flow can be well blocked after the first balloon is stretched. The first conduit and the pigtail tube are independent of each other and do not communicate with each other, and both are single-function tubes.

Further, the above-mentioned second balloon assembly includes a second balloon and a second catheter; the pigtail tube and the first catheter respectively pass through the second balloon and are sealedly connected with the second balloon; one end of the second catheter is connected to the second balloon The capsule is connected, the other end of the second conduit is close to the operation end, and the middle part of the second conduit is connected with the outer wall of the pigtail tube.

Moreover, the first conduit, the second conduit and the pigtail tube are all independent and different from each other, and all are single-function tubes.

Further, the diameter of the second balloon is larger than that of the first balloon.

Since the function of the first balloon is to block the flow of blood, the flow of blood does not need to be cut off, so the diameter of the first balloon is relatively small. The function of the second balloon is to compress the wound to stop bleeding, so the second balloon needs to be stretched sufficiently to achieve compression and stop bleeding. The diameter of the second balloon is thus greater than the diameter of the first balloon.

Further, the outer surface of the second balloon is provided with a hemostatic gel layer.

In the present invention, a hemostatic gel layer is arranged on the surface of the second balloon, which may accelerate the coagulation at the window, and through the expansion of the second balloon and the dual function of the hemostatic gel, hemostasis can be effectively performed, thereby shortening the hemostasis time. Reduce bleeding.

Further, the above-mentioned pigtail pipe is glued to the first conduit and the second conduit respectively.

Further, the side wall of the curved end is provided with a plurality of imaging holes.

The pigtail tube has good visibility and can be contrasted under X-ray fluoroscopy. A contrast hole is set outside the tail end of the pigtail tube to disperse the pressure of the contrast agent entering the blood vessel and prevent the contrast agent from damaging the vascular intima under high pressure. .

Further, the above-mentioned pigtails are single-J pigtails or double-J pigtails.

The present invention has the following beneficial effects:

(1) The present invention carries out radiography and placing the balloon in the same step, which reduces the operation time, the blood flow time is short, the amount of bleeding is small, and the mortality rate of the patient is reduced; Block the flow, reduce the amount of bleeding, and can also compress the wound to stop bleeding.

(2) The present invention can reduce the flow rate of blood and the amount of bleeding after blocking flow by the first balloon component, and it is convenient for the second balloon to compress the wound to stop bleeding.

(3) The second balloon of the present invention can not only stop bleeding by compression, but also stop bleeding through the hemostatic gel. Through the expansion of the balloon and the dual functions of the hemostatic gel, hemostasis can be effectively performed, thereby shortening the hemostasis time and reducing the amount of bleeding .

(4) The pigtail tube, the first catheter and the second catheter of the present invention are all single-function tubes, which are not connected. The first balloon and the second balloon can be stretched separately, and the deformation of each balloon is uniform, which can effectively Stopping blood flow and compressing wounds to stop bleeding.
