Abstract
A photocoagulation system is described herein that facilitates multi-spot laser treatment procedures inside the eye and close to the patient's retina. In one example embodiment, a modified endocular probe operates with a laser system to move the probe or a probe needle so as to project a multi-spot pattern on a patient's retina by controlling the rotation movement of the needle (and needle tip). In addition, the system facilitates maneuverability and angular deviation of the needle tip and synchronizes these different movements with the laser photocoagulator system so as to project the aiming beam and thereafter the laser treatment beam in the desired pattern location with the desired exposure time and power.
Claims20
A photocoagulation system including a system controller and a laser source for generating an aiming beam and a treatment beam, the system comprising:
- a probe having a distal end and a proximal end, the proximal end being coupled to a fiber optic cable that is coupled to the laser source, the distal end of the probe configured for ophthalmologic procedures and configured to have a longitudinal portion and an angled tip at the end of the longitudinal portion;
- wherein the distal end of the probe is configured to angularly rotate thereby forming at least one circle with spots located thereon that form alignment pattern and/or a treatment pattern of spots.
An endocular probe holder assembly comprising:
- a housing;
- a motor for longitudinal displacement of an endocular probe;
- a probe displacement sensor;
- and
- a control circuit member operatively coupled to the displacement motor and the displacement sensor and adapted to control the motor and the sensor;
- wherein the displacement motor is adapted to engage an actuator operatively coupled to the probe and configured to control angle displacement of the probe through a longitudinal movement, and wherein the displacement sensor is adapted to sense a displacement member located on the probe and configured to communicate angle displacement movement of the probe or probe tip to the control circuit member.
