摘要:
Electrically switchable multipoint probe laser (10) for use in ophthalmic surgery to photocoagulate a tissue, comprising: a cylindrical housing (30) having an interior region one or more lenses (40, 44) disposed within the interior region, each lens configured to transmit a laser beam being and a scanning system (42) disposed within the interior region, the scanning system a first cell scanning (110a) and a second cell scanning (110b) comprising, wherein the first cell scanning arranged to move the laser beam along a first coordinate axis and the second cell scanning being arranged to move the laser beam along a second axis orthogonal coordinate to the first coordinate axis to allow a guided dimensional beam, comprising each cell scanning an electrooptical materials (80), wherein the scanning system to be controlled by a controller (112) of the laser probe to perform the following during a series of iterations to produce a dot pattern of two-dimensional laser coincides with a two-dimensional pattern of inlet ends of a plurality of optical output fibers (56) of the laser probe: receiving controller voltages ( 112) of the laser probe and electrically guiding the laser beam with the electrooptical material cells scan from a current address to a next address in response to voltages, each cell scanning comprising: a first electrode layer (144) and a second electrode layer ( 150) opposite the first electrode layer an electro element (146) comprising the electrooptical materials (80) and disposed between the first electrode layer and the second electrode layer and the second electrode layer a plurality of electrodes strip type (152) including a first electrode strip type on a first side of the cell scanning and a second electrode strip type on a second side of the cell scanning comprising opposite the first side plan view of the cell scanning in which, for a guide direction given beam, the controller is arranged to apply a different voltage to each one of the electrodes of
