FIELD: medical engineering. SUBSTANCE: device has cylindric casing 1 two plates each consisting of two parts 2 and 3, cantilever 4 fixed on axial joint 5 mounted at the end of casing 1, axial joint 6 mounted on cantilever 4 having nonworking ends of plate ends 2 attached, and control tie-rod 7 longitudinally movably mounted in casing 1. Longitudinal groove 8 is made in cantilever 7 where pin 9 having tie-rods 10 at its ends connected with plate parts 2 is located. Control tie-rod 7 is fixed in the middle portion of pin 9. Plate parts 2 and 3 are connected by means of axial joint 11. One end of strip 12 is connected with plane part 2 by means of axial joint 13. Slide block 14 movable in guide member of longitudinal groove 15 made in part 3 of the plate is mounted on the other end of strip 12. Control tie-rod 7 is provided with push button 16, teeth 17 and fixing member 18 to secure its position. Handle 19 is mounted on casing 1. EFFECT: facilitated access to operation field. 5 dwg |
