Embodiment Construction

[0020] Some embodiments of the invention are discussed in detail below. In the embodiments to be described, specific technical terms are used for the sake of clarity. However, it is not intended that the present invention be limited to the specific technical terms so selected. Those skilled in the art will recognize that other equivalent components may be used and other methods developed without departing from the broad concepts of the invention. All cited documents cited anywhere in this specification are to be incorporated by reference as if each had been individually included.

[0021] Some embodiments of the present invention may provide a simple and efficient way to improve the accuracy and safety of microsurgery based on common-path optical coherence tomography (CP-OCT) distance sensors capable of surface tracking and motion compensation. Compact hand-held microsurgical tools. Some embodiments of the present invention utilize a single fiber optic probe as a CP-OCT dis...

Abstract

A motion-compensating surgical tool system includes a surgical tool that includes a hand piece and a moveable component, a drive assembly connecting the moveable component to the hand piece such that the moveable component is movable in an axial direction relative to the hand piece by the drive assembly. The motion-compensating surgical tool system also includes an optical detection system that includes an optical fiber attached to the moveable component with an end at a fixed distance to a distal-most portion of the moveable component. The optical detection system is configured to output a signal for the determination of a distance of the distal-most portion of the moveable component to a target during surgery.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 365,998, filed July 20, 2010, the entire contents of which are hereby incorporated by reference. [0003] This invention was made under Government Grant Nos. 1RO1EB007969-01 and 1R21NS063131-01A1 awarded by the Department of Health and Human Services (NIH). The US Government has certain rights in this invention. technical field [0004] The field of presently claimed embodiments of the invention relates to surgical tools and systems including surgical tools, and more particularly to surgical tools and systems with integrated surface tracking and motion compensation sensors. Background technique [0005] Retinal surgery is an example of microsurgery. In current practice, retinal surgery is performed under an operating microscope without manual instruments. Human limitations include inability to clearly view surgical targets, physiological hand trem...
