Pulling device for the optical waveguide of the insufficient vein closing laser

The closing laser optic fibre winch is composed of a pulling section (1) and drive section (2). In the pulling section body (1) there is a pulling mechanism composed of a drive roller (3) mounted on a shaft (4) rotating in a bearing (5) placed in the housing (6). The drive roller (3) has a toothed surface which ensures lack of slippage during movement of laser optic fibre (7). A laser fibre (7) holder is adjacent to the drive roller (3), in the form of a spring (8) connected with a holder lever (9), on which a holder roller (10) is placed. In the driving section body (2) a motor (11) is located, advantageously stepper motor, connected by a clutch (12) with a pulling part (1) roller (3).
