ANGIOPLASTY INSTRUMENT Russian patent published in 2014 - IPC A61B17/11 

FIELD: medicine.

SUBSTANCE: invention refers to medical instruments and may be used in surgery, particularly in angiosurgery, traumatology and abdominal surgery for manipulations on the vessels of different diameters. The instrument consists of pivotally connected braches with jaws, ring handles and ratchets. The jaws are paired, removable and replaceable platforms with semi-cylinders. The semi-cylinders have a radius of 2.5 to 15 mm and a length of 10 to 150 mm. The platforms with the semi-cylinders are fixed to a working surface of the jaws using external screws. The semi-cylinders have a circular ligature recess on the periphery from the outside. The branch handles are provided with a holding screw for the purpose of step-by-step decoupling and coupling of the handles and a working surface of the jaws. When coupling, the semi-cylinders form a tube a diameter of which may increase from 5 mm to 30 mm depending on the semi-cylinder radius on the replaceable platform and used for angiography. In the presence of the recovered blood flow in the ligated vessels, the instrument reduces a probability of developing thrombosis within the anastomosis, provides the normal function of the vascularised tissue and endothelium of the recovered vessels.

EFFECT: instrument provides the reliable and less traumatic fixation of the recovered vessel for a period of the surgery, a possibility to adapt the sutured ends, tight closure of the anastomosis ends, creating favourable conditions for faster anastomosis healing.
