Imaging tool to support eye surgery
An imaging tool with a tubular implement of minimal diameter for locating in a patient's eye and to extend an image capturing platform therefrom. The platform is uniquely sized for storage within the lumen or inner diameter of the implement, such as a thin film image sensor. However, a microchip package having a bulk footprint too large for the inner diameter of the implement may be displaced to another location of the tool such as within the adjacent, more sizeable handpiece or housing. Further, the platform may be expanded upon being exposed to the interior of the eye by the extending thereinto. Thus, an increased surface and pixel count may be provided for the imaging.
1. An imaging tool to support eye surgery, the imaging tool comprising:
a housing for physical manipulation by a surgeon during the eye surgery;
a tubular implement of a given inner diameter and extending from the housing for reaching into an eye of a patient during the eye surgery, the housing accommodating a microchip with a bulk footprint greater than the given inner diameter; and
a thin-film image capturing platform accommodated within the tubular implement, the thin-film image capturing platform extending from within the tubular implement for image capture of the eye during the eye surgery and configured for expanding upon the extending.
2. The imaging tool of claim 1 , further comprising thin film image sensors of the thin-film image capturing platform electronically coupling to the microchip through the tubular implement.
3. The imaging tool of claim 2 , wherein the coupling is attained through thin-film circuitry with conductive traces.
4. The imaging tool of claim 2 , wherein the thin film image sensors acquire at least about 10,000 pixels of image data upon the extending and expanding.
5. The imaging tool of claim 2 , wherein the thin film image sensors occupy more than about 5 mm of length within the given inner diameter of the tubular implement in advance of the extending therefrom.
6. An imaging tool to support eye surgery, the imaging tool comprising:
a housing for physical manipulation by a surgeon during the eye surgery;
a tubular implement of a given inner diameter and extending from the housing for reaching into an eye of a patient during the eye surgery;
a microchip accommodated by the housing and having a bulk footprint larger than the given inner diameter; and
a thin-film image capturing platform accommodated within the tubular implement, the thin-film image capturing platform extending from within the given inner diameter of the thin-film image capturing platform to acquire image data from within the eye and relay to the microchip during the eye surgery.
7. The imaging tool of claim 6 , wherein the thin-film image capturing platform is less than about 0.05 mm in thickness and comprises thin-film image sensors on a support substrate.
8. The imaging tool of claim 6 , wherein the given inner diameter is less than about 0.9 mm.
9. The imaging tool of claim 6 , wherein the thin-film image capturing platform is tailored to unfold upon the extending to expose a face thereof to a region of the eye for the image data.
10. The imaging tool of claim 9 , wherein the thin-film image capturing platform comprises ramped deflection edges to forcibly contact an interface of the tubular implement upon withdrawing of the thin-film image capturing platform into the given inner diameter, the deflection edges to promote re-folding of the thin-film image capturing platform during the withdrawing.
