摘要： An observation system for viewing light-sensitive tissue includes an illumination system configured to illuminate the light-sensitive tissue, an imaging system configured to image at least a portion of the light-sensitive tissue upon being illuminated by the illumination system, and an image display system in communication with the imaging system to display an image of the portion of the light-sensitive tissue. The illumination system is configured to illuminate the light-sensitive tissue with a reduced amount of light within a preselected wavelength range compared to multispectral illumination light, and the image of the portion of the light-sensitive tissue is compensated for the reduced amount of light within the preselected frequency range to approximate an image of the light-sensitive tissue under the multispectral illumination.

摘要： A force-sensing tool includes a tool shaft that has a proximal end and a distal end, a flexure section attached at a first end to the distal end of the tool shaft, a tool tip operatively connected to the flexure section such that axial forces applied to the tool tip are coupled primarily to a first portion of the flexure section and transverse forces applied to the tool tip are coupled primarily to a second portion of the flexure section, an axial force sensor coupled to the first portion of the flexure section, and a transverse force sensor coupled to the second portion of the flexure section. The axial force sensor responds to axial forces applied to the tool tip substantially independently of the transverse forces applied to the tool tip under a designed operating range of forces, and the transverse force sensor responds to transverse forces applied to the tool tip substantially independently of the axial forces applied to the tool tip under the designed operating range of forces.

摘要： The present invention is directed to a device to firmly grasp and manipulate delicate tissues in microsurgery, while precisely measuring tool-tissue interaction forces in three dimensions (x-y-z). The design enables precise measurement of forces at the tool tip without being influenced by other forces that may act on the tool shaft. The device of the present invention is capable of measuring axial (z) forces together with the transverse forces (x-y) on an actuated (not static) instrument. Fiber optic sensors are embedded into strategic locations of the design to decouple and precisely detect force components (x-y-z) separately. The force information is used to provide feedback to the operator, or to a robotic platform. The exerted forces on critical tissues, such as the retina in eye surgery, can be maintained at a safe level, clinical complications due to excessive forces can be lessened, safety, and outcome of microsurgical procedures can be enhanced.
