Description

Technical Field

[0001] The present invention relates to the technical field of medical device equipment, and particularly relates to an aortic arch descending aorta balloon occlusion perfusion tube. Background Art

[0002] Aortic dissection is a catastrophic cardiovascular disease, with a mortality rate close to 80% after onset, and the mortality rate increases by 1% per hour. In recent years, with the aging of the social population and the gradual increase in the number of hypertensive patients, the prevalence of aortic dissection has increased significantly. Surgical operation is the only method to cure aortic dissection. During the aortic arch replacement operation, it is necessary to temporarily stop the blood supply to the lower body under low-temperature conditions to obtain the time and surgical field for anastomosing the aorta. Exactly because of this, paraplegia and hepatorenal failure are surgical-related complications. With the application of urinary catheters and occlusion balloons during the operation, the absolute advantages of the aortic balloon occlusion perfusion tube in this surgical procedure are shown.

[0003] In the patent (application number: CN215537692U), a two-way balloon descending aorta occlusion perfusion tube is disclosed, including a perfusion cannula body and an occlusion balloon arranged at the front end of the perfusion cannula body. It is characterized in that: it further includes an antegrade descending aorta balloon perfusion part and a retrograde descending aorta balloon perfusion part arranged in the perfusion cannula body. The antegrade outlet end at the front end of the antegrade descending aorta balloon perfusion part and the retrograde outlet end at the front end of the retrograde descending aorta balloon perfusion part are respectively located at both ends of the occlusion balloon. This technology designs the antegrade and retrograde descending aorta balloon perfusion parts, with reasonable structure and novel design. During the operation of treating the great vessels of the heart, the antegrade descending aorta balloon perfusion part can be used to block the blood circulation in the descending aorta and perfuse the descending aorta, or the retrograde descending aorta balloon perfusion part can be used through the femoral artery to block the blood circulation in the descending aorta and perfuse the descending aorta. The operation is simple, the perfusion is reliable, the surgical safety is improved, and the occurrence of complications is reduced.

[0004] The following technical problems exist in the actual use of this patent and the prior art:

[0005] 1. Currently, when replacing the lesion location, it is impossible to simultaneously perform perfusion of the aortic arch branch area and the whole body. Only the methods of lower body circulatory arrest and selective cerebral perfusion can be used. However, this method requires deep hypothermia and strict shortening of the operation time to avoid nervous system and spinal cord injuries.

[0006] 2. At the same time, when inflating the aortic balloon by perfusion, since a large number of perfusion tubes are required, when multiple aortic balloons need to be perfused, medical staff need to perform perfusion through the injection device in sequence, which is rather troublesome to use and not convenient to simultaneously inflate and occlude multiple aortic balloons during use. Summary of the Invention

[0007] The object of the present invention is: to solve the above problems, the present invention provides an aortic arch descending aorta balloon occlusion perfusion tube.

[0008] The present invention specifically adopts the following technical solutions to achieve the above object:

[0009] An aortic arch descending aorta balloon occlusion perfusion tube includes a connecting pipe seat, and one end of the connecting pipe seat is fixedly connected with an aortic balloon catheter;

[0010] The aortic balloon catheter is communicated with the connecting pipe seat. The aortic balloon catheter is arranged as a double-lumen catheter. One end of the aortic balloon catheter is fixedly connected with an aortic occlusion balloon, and one of the cavities is communicated with it. The tail end of the aortic balloon catheter is fixedly connected with an aortic Luer connector;

[0011] One end of the connecting pipe seat is fixedly connected with aortic arch branch balloon catheters. There are three aortic arch branch balloon catheters, and all of them are communicated with the connecting pipe seat. The aortic arch branch balloon catheter is arranged as a double-lumen catheter. One end of the aortic arch branch balloon catheter is fixedly connected with an aortic arch branch occlusion balloon, and one of the cavities is communicated with it. The tail end of the aortic arch branch balloon catheter is fixedly connected with an aortic arch branch Luer connector;

[0012] One-way valves are arranged inside the aortic Luer connector and the aortic arch branch Luer connector. One end of the connecting pipe seat far from the aortic balloon catheter is fixedly communicated with a connecting sleeve. One end of the connecting sleeve is fixedly connected with a three-way joint, and a pressure relief hole is arranged on one side of the connecting sleeve.

[0013] Further, a perfusion mechanism is arranged above the connecting pipe seat. The perfusion mechanism includes a perfusion tube arranged above the connecting pipe seat. The bottom of the perfusion tube is fixedly communicated with the aortic Luer connector and the aortic arch branch Luer connector respectively. An injection port is opened at the top of the perfusion tube.

[0014] Further, a connecting rod is fixedly installed between the upper and lower sides of the perfusion tube. A sealing plate is rotatably installed on the surface of the connecting rod. There are two groups of sealing plates symmetrically arranged, and both are slidably connected with the bottom of the perfusion tube.

[0015] Further, sliding grooves are opened on the surface of the perfusion tube. There are two groups of sliding grooves symmetrically arranged. An L-shaped rod is fixedly installed at the top of the sealing plate, and the L-shaped rod extends to the outside of the perfusion tube through the sliding groove.

[0016] Further, a sealing strip is fixedly installed on the inner wall of the sliding groove.

[0017] Further, the sealing plate is arranged as a sector.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. By providing the aortic balloon catheter and the aortic arch branch balloon catheter, the present invention can simultaneously perfuse the aortic arch branch region and the whole body. At the same time, when vascular occlusion is required, it can also perform occlusion simultaneously, which is convenient for medical staff to use during treatment operations, can achieve single-operator occlusion, can avoid aortic arch branch perfusion ischemia caused by asynchronous operations, and can complete simultaneous perfusion of the upper and lower limbs.

[0020] 2. Through the provided perfusion mechanism, when used by medical staff, the greater the angle of rotation of the sealing plate driven by pushing the L-shaped rod, the more aortic inner Luer connectors or aortic arch inner Luer connectors are opened, and the more balloons are inflated. Multiple blood vessels can be occluded simultaneously. Only by using the perfusion tube can multiple balloons be inflated and occluded, which is relatively convenient to use. At the same time, it can occlude the lesion area in time before the lesion occurs, effectively protecting the safety of patients. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Aortic arch descending aorta balloon occlusion perfusion tube according to a preferred embodiment of the present invention will be described in detail below.

[0029] Example 1, as Figures 1-5 shown, an aortic arch descending aorta balloon occlusion perfusion tube includes a connecting socket 1, and one end of the connecting socket 1 is fixedly connected to an aortic balloon catheter 2;

[0030] The aortic balloon catheter 2 communicates with the connecting socket 1. The aortic balloon catheter 2 is set as a double-lumen catheter. One end of the aortic balloon catheter 2 is fixedly connected to an aortic occlusion balloon 3, and one of the cavities communicates with it. The tail end of the aortic balloon catheter 2 is fixedly connected to an aortic luer connector 4;

[0031] One end of the connecting socket 1 is fixedly connected to three aortic arch branch balloon catheters 5. The aortic arch branch balloon catheters 5 are all communicated with the connecting socket 1. The aortic arch branch balloon catheters 5 are set as double-lumen catheters. One end of the aortic arch branch balloon catheter 5 is fixedly connected to an aortic arch branch occlusion balloon 6, and one of the cavities communicates with it. The tail end of the aortic arch branch balloon catheter 5 is fixedly connected to an aortic arch branch luer connector 7;

[0032] One-way valves are arranged inside both the aortic luer connector 4 and the aortic arch branch luer connector 7. One end of the connecting socket 1 away from the aortic balloon catheter 2 is fixedly communicated with a connecting sleeve 8. One end of the connecting sleeve 8 is fixedly connected to a three-way joint 9. A pressure relief hole is arranged on one side of the connecting sleeve 8;

[0033] Medical staff connect the three-way joint 9 to the blood supply system, and then connect the aortic balloon catheter 2 and the aortic arch branch balloon catheter 5 to the patient's blood vessels respectively. Then the medical staff start the blood supply system. The blood supply system injects blood into the three-way joint 9. The blood is transported to the connecting sleeve 8 through the three-way joint 9, and then transported to the connecting socket 1 through the connecting sleeve 8. The connecting socket 1 transports the blood into the aortic balloon catheter 2 and the aortic arch branch balloon catheter 5, and then transports it into the patient's blood vessels for blood perfusion. When it is necessary to occlude the blood vessels, the medical staff inject the liquid through the corresponding aortic luer connector 4 or aortic arch branch luer connector 7 into the aortic balloon catheter 2 or the aortic arch branch balloon catheter 5 through an injection device. Since they are all double-lumen catheters, the blood is transported through one of the cavities during transportation and transported into the aortic occlusion balloon 3 or the aortic arch branch occlusion balloon 6 to inflate it and block the corresponding blood vessels. Further, the aortic occlusion balloon 3 and the aortic arch branch occlusion balloon 6 can be replaced by one-way observation balloons for medical staff to sense and observe the pressure condition inside the balloons during the clinical process.

[0034] Example 2, as Figures 1-5As shown in the figure, an aortic arch descending aorta balloon occlusion perfusion tube includes a perfusion mechanism 10 disposed above a connecting socket 1. The perfusion mechanism 10 includes a perfusion tube 101 disposed above the connecting socket 1. The bottom of the perfusion tube 101 is fixedly communicated with a femoral artery luer connector 4 and an aortic arch branch luer connector 7 respectively. An injection port 102 is opened at the top of the perfusion tube 101.

[0035] Medical staff can connect an injection device to the injection port 102, and then inject liquid into the interior of the perfusion tube 101 through the injection device. Since both the femoral artery luer connector 4 and the aortic arch branch luer connector 7 are communicated with the perfusion tube 101, the aortic occlusion balloon 3 and the aortic arch branch occlusion balloon 6 can be inflated and occluded simultaneously through them.

[0036] Embodiment 3, as Figures 1-5 As shown in the figure, an aortic arch descending aorta balloon occlusion perfusion tube includes a connecting rod 103 fixedly installed between the upper and lower sides of the perfusion tube 101. A sealing plate 104 is rotatably installed on the surface of the connecting rod 103. Two groups of sealing plates 104 are symmetrically arranged and are both slidably connected to the bottom of the perfusion tube 101. Sliding grooves 105 are opened on the surface of the perfusion tube 101. Two groups of sliding grooves 105 are symmetrically arranged. An L-shaped rod 106 is fixedly installed at the top of the sealing plate 104. The L-shaped rod 106 extends to the outside of the perfusion tube 101 through the sliding groove 105. A sealing strip 107 is fixedly installed on the inner wall of the sliding groove 105. The sealing plate 104 is set as a fan shape.

[0037] The arranged sealing plate 104 can block and seal the femoral artery luer connector 4 and the aortic arch branch luer connector 7. When it is necessary to inject and occlude one or more of the aortic occlusion balloons 3 or the aortic arch branch occlusion balloons 6, medical staff manually push the two L-shaped rods 106. The L-shaped rods 106 drive the sealing plate 104 to rotate on the surface of the connecting rod 103 and slide at the bottom of the perfusion tube 101 at the same time. The greater the angle at which the medical staff push the L-shaped rods 106 to drive the sealing plate 104 to rotate, the more femoral artery luer connectors 4 or aortic arch branch luer connectors 7 are opened, and the more balloons are inflated. Multiple blood vessels can be occluded simultaneously. Only through the perfusion tube 101, multiple balloons can be inflated and occluded, which is relatively convenient to use.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
