Purpose of the development: The apparatus is designed to perform surgical operations on internal organs.

Recommended application field: Medicine.

Advantages over analogues: The device will allow for operations on the liver, stomach, removal of malignant tumors virtually no damage the vascular system. The developers claim that the new scalpel significantly superior to the best foreign counterparts in cost, reliability, efficiency and the possibility of multiple use.

The development stage readiness: Ready for application

Technical and economic effect: The liquid jet scalpel was successful clinical trials on animals in the department of Experimental Surgery Institute of Surgery and Transplantation.

Description of the development:
()
A group of scientists of the National Institute of Aerospace aviauniversiteta Ukraine has developed a liquid jet scalpel, which virtually eliminate cases of damage to the vascular system during operations on the stomach and liver in removing malignant tumors. The inventive apparatus uses a so-called ink-jet technology, which previously has been used successfully in the aviation industry. Now it can be used in medicine for the operations in the internal organs. Affecting high pressure, the surgeon will be able to virtually no damage the vascular system will remove the non-muscle tissue, which will minimize blood loss and significantly reduce the risk of operations. Scientists have conducted successful tests on animals scalpel. To launch the device in mass production left to pass the necessary certification. The design implements a method based on the erosion of the parenchymal tissue of high pressure liquid stream that allows you to remove the parenchyma without damaging the vascular system. The device consists of a jet scalpel, wherein the liquid jet is formed of small. It acts on the cloth supply system that supplies the hydraulic fluid at a predetermined pressure to the jet scalpel. The power supply system consists of a gas cylinder, two pressure gauges, pressure regulator, gidrogazovogo vydavlivatelya, two valves, filling the vessel. The apparatus operates as follows: gas cylinder charged with compressed air to a pressure of 15 MPa, which is controlled by a manometer. The machine is in working condition the opening of a valve tap, through which compressed air is supplied to the input of gas reducer. Inlet pressure reducer controlled by a spring and controlled torque gauge. Next, the compressed air enters the gas passage vydavlivatelya. UNITY vydavlivatelya working fluid is carried out at a gas valve open vessels, which in operation is closed. The working fluid from the fluid enters the cavity vydavlivatelya gidroprovid flexible, and through it - the jet scalpel, which is the size of a fountain pen with a button on the side. With the push of a button from the nozzle of a scalpel should be fluid flow, which provides a force on the fabric, which operate.
