FIELD: medicine.
SUBSTANCE: invention refers to medical equipment, particularly to lens or other tissue extraction in ophthalmic surgery. Surgical device for cutting a lens inside a capsular eye bag comprises a rod and a dissecting element. Rod has a distal end and a lumen formed through the rod. Lumen has a longitudinal axis and a distal end. Dissecting element has the first side and the second side. Dissecting element is made with possibility of movement relative to the rod from the first configuration of introduction in the direction of the second configuration of the grip, in which the greater section of the dissecting element is pulled out from the distal end of the lumen. At least a section of the dissecting element is located inside the lumen when it is in the first injection configuration. Dissecting element in the first configuration of introduction and the distal end of the rod are made so that to introduce them into the anterior eye chamber through the incision. Movement from the first insertion configuration towards the second configuration of the grip forces at least one of the first side and the second side of the dissecting element to move in the distal direction relative to the distal end of the rod to form an open area limited by the dissecting element and the distal end. At least a section of the dissecting element limits an open area extending proximally in relation to the distal end of the rod. Second configuration of the incision of the dissecting element has such a size and shape to ensure the movement of the dissecting element between the capsular sac and the crystalline lens. Crystalline lens remains in the capsular sac in order to capture a section of the crystalline lens in the open area. Slider is operably coupled with dissecting element. Engine is configured to tension the dissecting element to reduce the open area and to cut the crystalline lens.
EFFECT: use of the invention provides the effective crystalline lens grinding into small fragments and a cathedral of these fragments.
