Adapter to couple a mobile phone to an endoscope
A scope adapter for coupling a phone to an endoscope includes a base having a phone receiving portion for receiving and releasably supporting a phone. A first base end and a second base end define extents of a base cavity. A shaft is connected at opposite ends to each of the first and second base ends and spans across the base cavity. A threaded shaft is rotationally supported at opposite ends to the first and second base ends and spans across the base cavity. An endoscope positioned within the cavity is movably disposed along the shaft in each of a first direction and an opposite second direction by axial rotation of the threaded shaft. The endoscope includes a lens aperture that is positioned with respect to the phone receiving portion by displacement of the endoscope in either the first or second directions.
1. A scope adapter for coupling a mobile computing device to an endoscope, comprising:
a platform base having a planar surface that extends onto a mobile computing device receiving portion that is capable of releasably receiving and stably supporting a mobile computing device,
said platform base having a first base end and a second base end defining an interior cavity housing a positioning ring coupled to an adapter ring that is capable of coupling with a telescopic lens component or an endoscope adapter of the endoscope;
a smooth exterior shaft connected at opposite ends thereof to each of the first and second base ends and spanning across the interior cavity, wherein a portion of said exterior shaft is further slidably positioned within a smooth bore in the positioning ring;
a threaded shaft rotatably connected at opposite ends thereof to each of the first and second base ends and parallel to the smooth exterior shaft, wherein a portion of said threaded shaft is further rotatably positioned within and engaging a threaded bore in the positioning ring, such that when said threaded shaft is axially rotated the positioning ring and thereby the adapter ring is incrementally displaced for fine adjustment in either a first or second opposing direction parallel to and along the exterior shaft and threaded shaft to assist in placing a lens aperture associated with the positioning ring in alignment with a camera lens of the mobile computing device;
the mobile computing device receiving portion including a first fixed clamp located proximate to and in a direction parallel to the first base end of the platform base, and a second spring-loaded displaceable clamp located proximate to and in a direction parallel to the second base end of the platform base and biased toward the first fixed clamp, such that the first fixed clamp and second spring-loaded displaceable clamp define first and second contact supports that are capable of releasably receiving and stably supporting the mobile computing device there between;
the first fixed clamp further including an L-shaped bar having a major length bar first portion that is slidably received in the first fixed clamp and a minor length bar second portion oriented perpendicular to the bar first portion, wherein the position of the bar second portion can be adjusted by movement either toward or away from said first fixed clamp and secured using a releasable fastener, said bar second portion defining a third contact support to the mobile computing device which in concert with the first and second contact supports is capable of providing a repeatable position for alignment of the lens aperture with the camera lens.
2. The scope adapter for coupling a mobile computing device to an endoscope of claim 1 , wherein the smooth exterior shaft is connected at opposite ends thereof to distal ends of each of the first and second base ends, and the threaded shaft is rotatably connected at opposite ends thereof to each of the first and second base ends proximate to the mobile computing device receiving portion.
3. The scope adapter for coupling a mobile computing device to an endoscope of claim 2 , wherein the platform base is U-shaped and the interior cavity is U-shaped.
4. The scope adapter for coupling a mobile computing device to an endoscope of claim 1 , further including an alignment wheel rotatably supported in an elongated slot of the first fixed clamp, the wheel continuously contacting an upper facing surface of the bar first portion, and wherein rotation of said wheel allows for fine adjustment of the bar first portion to adjust a position of the bar second portion with respect to the first fixed clamp.
5. The scope adapter for coupling a mobile computing device to an endoscope of claim 4 , wherein a resilient material pad is positioned on an inside facing surface of the first fixed clamp and second spring-loaded displaceable clamp to assist in frictionally engaging the mobile computing device.
6. The scope adapter for coupling a mobile computing device to an endoscope of claim 5 , wherein the first fixed clamp and second spring-loaded displaceable clamp have inside facing surfaces that are each oppositely inwardly angled defining mirror image acute angles, such that when a mobile computing device is placed between said first and second clamps there is produced a downward directed force that tends to hold the mobile computing device in contact with the planar surface of the mobile computing device receiving portion.
