PNEUMATIC FORCEPS AND METHOD FOR TAKING AND POSITIONING CONTACT LENSES OR THE LIKE ELEMENTS ON OBJECTS USING THE PNEUMATIC FORCEPS Russian patent published in 2003 - IPC

FIELD: medical engineering. SUBSTANCE: device has two sucking disk areas lying opposite that are higher and thicker. The sucking disk cross-section is optionally elongated in the direction of mentioned areas of its wall. Rod is optionally disposed in the hole on the sucking disk preventing from excessive contact lens suction into the sucking disk and participating in organizing one or more lateral openings for making communication between internal sucking disk cavities and pneumatic pear. Another version of the device deals with sucking disk having protrusion with an opening for holding contact lens by sucking pressure. Sucking disk wall has two opposite-lying slits. The pneumatic pear optionally has rubber balloon disposed in the hole for preventing the contact lens from being excessively sucked in into the rod opening. The pneumatic pear internal cavity partially filled with balloon communicates with the opening via one or more slots on the balloon end face. Both versions of the device have sucking disk wall continued in the pneumatic pear direction or transformable into pneumatic pear wall. The first version involves taking the device with fingers placed on the sucking disk near its bottom on the same side as the elongated sucking disk wall areas are. The second version involves taking the device with fingers placed on the pneumatic pear near sucking disk bottom on the same side as its elongated wall areas are. The third version involves taking the device with fingers placed on the sucking disk near its bottom from the slot sides. When pressing the fingers close together, the edges of the elongated areas go apart in all versions and the pneumatic pear becomes compressed. When reducing finger compression degree the mentioned edges of the elongated areas come closer and the pneumatic pear becomes more released. As a result of the action edge areas catch the contact lens being taken from object and pear releasing maintains lens suction to sucking disk edge or to sucking disk protrusion opening. The diverging edge areas leave the lens to positioned on the object and pear compression causes repulsion of the lens by means of compressed air from the sucking disk to the object. EFFECT: enhanced effectiveness and reliability of operation; simplified design. 17 cl, 3 tbl
