Abstract
Embodiments related to medical imaging devices including rigid imaging tips and their methods of use for identifying abnormal tissue within a surgical bed are disclosed.
Claims70
A handheld medical imaging device comprising:
- a photosensitive detector comprising a plurality of pixels;
- and
- a rigid imaging tip optically associated with the photosensitive detector, wherein the rigid imaging tip includes a distal end defining a focal plane at a fixed focal distance relative to the photosensitive detector, and wherein the distal end of the rigid imaging tip is constructed to be placed in contact with tissue and maintain the tissue at the focal plane.
A hand held medical imaging device comprising:
- an imaging device body;
- a rigid imaging tip distally extending from the imaging device body, wherein a distal end of the rigid imaging tip defines a focal plane with a field of view with a lateral dimension between about 10 mm to 50 mm inclusively, and wherein the rigid imaging tip includes a proximal portion and a distal portion that is angled by about 25° to 65° inclusively relative to the proximal portion, wherein a length of the distal angled portion is between about 10 mm to 65 mm, and wherein an optical axis passes through the rigid imaging tip from the distal end of the rigid imaging tip to the proximal end of the rigid imaging tip.
A hand held medical imaging device comprising:
- a photosensitive detector comprising a plurality of pixels;
- and
- a rigid imaging tip optically associated with the photosensitive detector, wherein the rigid imaging tip includes a distal end defining a focal plane relative to the photosensitive detector, wherein the distal end of the rigid imaging tip is open, and wherein the rigid imaging tip includes at least one opening on a side of the rigid imaging tip that is sized and shaped to provide surgical access to the distal end of the rigid imaging tip.
A hand held medical imaging device comprising:
- a rigid imaging tip including a proximal portion and a distal portion including a distal end, wherein the distal end includes an opening to provide access to a surgical bed, and wherein one or more supports extend between the proximal portion and the distal portion;
- and
- a photosensitive detector optically associated with the opening located in the distal end of the rigid imaging tip.
A handheld medical imaging device comprising:
- a rigid imaging tip including a distal end defining a field of view;
- a photosensitive detector optically associated with the rigid imaging tip;
- a first illumination source adapted and arranged to provide light with a first wavelength to the distal end of the rigid imaging tip;
- and
- a second illumination source adapted and arranged to provide light with a second wavelength to the distal end of the rigid imaging tip, wherein the first wavelength and the second wavelength are different, wherein the first illumination source and the second illumination source are adapted to alternatingly pulse.

A handheld medical imaging device comprising:
- a rigid imaging tip including a distal end defining a focal plane with a field of view;
- a photosensitive detector optically associated with the rigid imaging tip;
- an aperture located between the photosensitive detector and the rigid imaging tip, wherein the aperture has with a diameter between about 5 mm to 15 mm inclusively;
- and
- a first illumination source adapted and arranged to provide between about 10 mW/cm2 to 200 mW/cm2 of light at the focal plane, wherein the light has a wavelength between about 300 nm to 1,000 nm.
