Scientists invented a unique device for heart surgery

Scientists at the National University of Technology Research "MISiS" joined Australian colleagues from the medical company "Endogene-Globetek" to devise a unique device for heart surgeries.

With this device, doctors can perform coronary artery bypass surgery without stopping the heart, nor need to open the chest.

The stapler clamps created by scientists to stitch super-fragile blood vessels allow them to not only connect capillaries quickly and safely, but also significantly reduce post-operative recovery time. The invention from Russia-Australia medical cooperation was awarded the prestigious award at the 44th International Patent Exhibition INVENTIONS GENEVA.

A standard surgery usually lasts an average of 4 to 5 hours and requires a temporary cardiac arrest, which will be accompanied by a long-term follow-up of rehabilitation. Moreover, there is always an unfortunate risk ratio, after about 5% of cases, it is impossible to restart the heart.

The new device facilitates the doctors to perform the operation to perform direct operations on the heart that is still beating. In order to ensure access to the heart, instead of opening the sternum of the chest as it has done before, now the doctor only needs to puncture the two holes and stitch. The length of this sophisticated procedure is about an hour and the patient can be discharged home after only one day or night.

The miraculous power of stapler clamping creative is contained in the use of special alloys from "Nitinol" with super elastic properties, ie the ability of the self-healing metal. Dress the original shape after there is abnormal distortion because of great pressure. The hangers are arranged within the distance away from the end of the clamp, but the outer casing is made of polymer.

"Currently, there are no inventions similar to our patent in the world. The main advantage of this device is the minimum stitch time while preserving the reliability of capillary connections. Moreover, learning to use the device is also very easy.It can be used in abdominal surgery to sew blood vessels of other hollow structures, such as aortic aneurysms or intestinal operations. " - lead the research team, Professor Sergei Prokoshkin of MISiS University of Technology Research said.

Now scientists continue to improve the technology (the Russian side handles the clamps, while Australia - the outer cover).

According to scientists, cardiovascular disease is the leading "killer" in all types of illnesses. Every year in the world, diseases in the cardiovascular system cause 17 million deaths.
