Abstract
A device for stopping a bleeding in living tissue in humans and animals by forming a necrotic layer in the tissue comprises a member for generating a dynamic plasma flow capable of wholly or partially penetrating an outer, porous layer of the necrotic layer. The device also has an electrosurgical generator arranged to transfer electric energy to the inner limit of the porous layer through a circuit that comprises the plasma flow and the tissue.
Claims8
A device for stopping a bleeding in living tissue in humans and animals by forming a necrotic layer in the tissue, the device comprising:
- a means for generating a dynamic plasma flow, the plasma flow forms a necrotic layer comprising a porous layer and a compact layer when directed at the tissue, and the plasma flow being capable of wholly or partially penetrating an outer, porous layer of the necrotic layer;
- and
- an electrosurgical generator arranged to transfer electric energy to an inner limit of the porous layer in the necrotic layer through a circuit, the circuit comprises the plasma flow and the tissue.
A method for stopping a bleeding in a living tissue in humans and animals by forming a necrotic layer in the tissue, comprising:
- generating a dynamic plasma flow capable of wholly or partially penetrating an outer, porous layer of the necrotic layer;
- directing said dynamic plasma flow in the form of a plasma jet towards a bleeding tissue so that the necrotic layer comprising a porous and a compact layer forms in the tissue, the plasma flow capable of wholly or partially penetrating an outer, porous layer of the necrotic layer;
- transferring electric energy to the tissue through a circuit which comprises the plasma jet and the tissue, and
- conducting the electric energy through the plasma jet to an inner limit of the porous necrotic layer for increasing the thickness of the compact layer.
