Detailed Description

In order to make the technical means, creation features, achievement purposes and effects of the present invention easy to understand, the present invention is specifically described below with reference to the embodiments and the accompanying drawings.

As shown in fig. 1, the abdominal aorta occluder 100 provided in this embodiment comprises an inner core 1, an occlusion balloon 2, a guide wire 3, a sheath tube 4, a syringe 5, a luer connector, a see-through marker band, and an arterial puncture needle (not shown).

The inner core 1 includes a tube portion 11 and a seat portion 12 mounted at one end of the tube portion 11. The tube portion 11 has two channels, one of which is a guidewire channel 13 and the other of which is a balloon inflation channel 14. The seat part is provided with a guide wire opening 15 communicated with the guide wire channel 13 and a filling opening 16 communicated with the balloon filling channel 14, wherein the filling opening 16 is provided with a luer connector.

Luer fittings are convenient connection devices for use in the medical industry, which greatly simplifies the management of liquid and gaseous medical fluids. Luer connector can switch 4 infusion bags under the prerequisite of not plug patient infusion needle. Such a fitting also allows multiple fluids that are compatible with each other to be managed using the same tubing, thereby reducing trauma to the patient. In this embodiment, luer fitting 2 is used to connect a pressure pump, which in turn inflates occlusion balloon 2.

In this embodiment, the guidewire channel 13 is located at the center of the inner core 1, and the balloon filling channel 14 is located on the peripheral side of the guidewire channel 13. To facilitate entry of the inner tube into the abdominal aorta, a tapered portion is provided at one end of the tube portion 11.

The occlusion balloon 2 is mounted at the other end of the tube portion and is in communication with the balloon inflation channel 14.

The occlusion balloon 2 is made of a balloon with a compliant polyurethane, and the occlusion balloon 2 can be inflated by 16mm-32 mm. Furthermore, the occlusion balloon 2 has a marker at the head and tail, so that the position of the non-expanded occlusion balloon 2 can be shown under fluoroscopy.

The center of the blocking sacculus 2 is provided with a through hole matched with the guide wire channel 13, and the guide wire 3 sequentially passes through the inner core 1 and the blocking sacculus 2 through the guide wire channel 13 and the through hole. In this embodiment, the guidewire 3 is 0.035 inches in gauge.

In this embodiment, to prevent blood from flowing out of the guide wire channel 13, a one-way valve is provided at the guide wire port 15, which valve abuts the guide wire to prevent blood from flowing out.

The sheath tube 4 has a tube body 41 fitted around the outside of the tube portion 11 of the core 1, an operation portion 42 attached to one end of the tube body, and a flushing port 43 and a valve port 44 provided in the operation portion 42.

The flushing port 43 is used for flushing and infiltrating the inner surface of the sheath tube 4, so that the inner core 1 can pass through the sheath tube 4 more easily. The valve port 44 is used to connect the syringe 5 to a pressurized contrast device for injecting contrast media to meet the contrast requirements.

The use of contrast agents in surgery has two main effects. The device is used for injecting through a valve port, so that intraoperative radiography is realized, and the positions of the abdominal aorta and the double iliac arteries can be displayed under fluoroscopy. Secondly, the balloon is pressurized and injected through a pressure pump, visible expansion of the blocking balloon under fluoroscopy is realized, and accordingly abdominal aorta blood flow blocking is realized.

In the present embodiment, the sheath 4 is sized to be 18F, and the length of the body portion 41 is adapted to the length of the core 1.

The perspective mark belt is arranged on the sheath tube 4 and used for positioning the position of the blocking saccule 2 in the sheath.

The arterial puncture needle is used to form a puncture point at the skin such that the body portion of the sheath extends into the arterial vessel.

In this embodiment, the inner core 1, the blocking balloon 2 and the sheath tube 4 are designed as an integral body, which is convenient for a user to carry.

The abdominal aorta blocker 100 provided in this embodiment is used for hemostasis: puncture femoral artery, introduce the guide wire 3 under the fluoroscopy, introduce and block the sacculus 2 along the guide wire 3, the radiography shows position and form of abdominal aorta roughly in the art, the guide wire 3 is selected the abdominal aorta excessively, the pressure pump draws the contrast medium after diluting, connect the luer of inner core tail end, pressurize and expand under the fluoroscopy, block the abdominal aorta, realize hemostasis.

In addition, contrast media is injected into the inner core 1 through the valve port 44 and imaged by a simple X-ray machine procedure, so that the occlusion balloon occludes the arterial vessel.

Effects and effects of the embodiments

According to the abdominal aorta blocker related by the embodiment, the inner core with the guide wire channel and the balloon filling channel is arranged in the sheath tube, the blocking balloon is installed at the front end of the inner core and communicated with the balloon filling channel, and the guide wire penetrates through the inner core and the blocking balloon, so that when hemostasis is needed, femoral artery puncture is performed, the guide wire is introduced under fluoroscopy, the blocking balloon is introduced along the guide wire, the position and the shape of the abdominal aorta are roughly displayed by intraoperative radiography, the guide wire is selected to be superior to the abdominal aorta, the diluted contrast medium is pumped by the pressure pump, the luer at the tail end of the inner core is connected, pressurized expansion is performed under fluoroscopy, the abdominal aorta is blocked, and hemostasis is realized. Therefore, the abdominal aorta blocker provided by the embodiment has the advantage of simple operation.

The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.
