Abstract

PURPOSE: Retinal microsurgery requires extremely delicate manipulation of retinal tissue where tool-to-tissue interaction forces are usually below the threshold of human perception. Creating a force-sensing surgical instrument that measures the forces directly at the tool tip poses great challenges due to the interactions between the tool shaft and the sclerotomy opening. METHODS: We present the design and analysis of a force measurement device that senses distal forces interior to the sclera using 1-cm long, 160 microm diameter Fiber Bragg Grating (FBG) strain sensors embedded in a 0.5 mm diameter tool shaft. Additionally, we provide an algorithm developed to cancel the influence of environmental temperature fluctuations. RESULTS: The force-sensing prototype measures forces with a resolution of 0.25 mN in 2 DOF while being insensitive to temperature. CONCLUSION: Sub-millinewton resolution force sensors integrated into microsurgical instruments are feasible and have potential applications in both robotic and freehand microsurgery.

  • Micron is a handheld actively stabilized 3-DOF micromanipulator designed to remove unintentional motion and enhance positional accuracy.

    “Micron is a handheld actively stabilized 3-DOF micromanipulator that is mainly designed to remove unintentional motion and enhance positional accuracy [16].”

    From Preliminary evaluation of a micro-force sensing handheld robot for vitreoretinal surgery (2012) · cites this paper as [16]

    The Introduction discusses imprecise movements caused by physiological tremor, but does not describe Micron. Searches for Micron and active stabilization found no passage identifying it as a handheld 3-DOF micromanipulator or stating its design purpose. The paper instead describes a force-sensing tool. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Micron can sense its own motion, estimate the undesired hand tremor component in real time, and move its tip to counteract this component.

    “This micromanipulator robot can sense its own motion, estimate the undesired hand tremor component in real time, and moves the tool tip relative to the handle to counteract this component.”

    From Preliminary evaluation of a micro-force sensing handheld robot for vitreoretinal surgery (2012) · cites this paper as [16]

    The Introduction identifies physiological tremor as a limitation of retinal microsurgery, but does not describe a device that cancels it. The Results describe force sensing at the tool tip, not sensing motion, estimating tremor in real time, or moving the tip relative to the handle. Searches for Micron and tremor-cancellation mechanisms found no passage addressing those capabilities. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
