Multi-function surgical instrument for facilitating ophthalmic laser surgery



Multi-function surgical instrument for facilitating ophthalmic laser surgery



Official Gazette of the United States Patent & Trademark Office Patents 1265(4), Dec 24



A multi-function surgical instrument for facilitating ophthalmic surgery of the eye by laser means. Included are a lower ring and an upper ring. The lower ring includes a central aperture to capture the limbus and aid in positioning of the eye. Protuberances on the lower surface of the lower ring, application of vacuum between the lower surface of the ring and the eye, or both may be used to more firmly grip the eye. Ports disposed on the upper surface of the lower ring and connected to a vacuum source may be used to control hydration of the surgical field. Attached to and extending above the upper surface of the lower ring is a sterile platform for reposing temporarily removed tissues during the administration of laser pulses to other tissues. The upper ring is disposed above the surgical bed. Ports disposed along the upper ring and connected to a vacuum source may be used to control smoke and splatters resulting from the ablative procedure and create additional airflow to further control hydration of the surgical field.
