Green photocoagulator laser is a frequency doubled diode pumped solid state laser ophthalmic photocoagulation system that produces a 532 nm (green) wavelength light as the treatment beam. It can be used to coagulate the target tissue efficiently and safely, and the system can be applied to transpupillary photocoagulation procedures using a slit-lamp or indirect ophthalmoscope and intraocular photocoagulation procedures using an endophotocoagulation probe.
The grooved director is used to expand a vein, to help a drain tube or drainage device such as angular spring forceps into a vein for drainage. It is traditionally used in neurosurgery and opthalmic surgery.
Ground Electrodes are used for single-channel recording. It is made and stored in the refrigerator for several weeks before use. They prevent artifacts and cross talk.
