Abstract

A surgical imaging device and method configured to be inserted into a surgical site. The surgical imaging device includes a plurality of prongs. Each one of the prongs has an image sensor mounted thereon. The image sensors provide different image data corresponding to the surgical site, thus enabling a surgeon to view a surgical site from several different angles. The prongs may be moveable between a first position, suitable for insertion through a small surgical incision, and a second position, in which the prongs are separated from each other. In addition, the prongs may be bendable.

The surgical imaging device of claim 1, wherein the flexible prong is configured to bend from the first condition to the second condition, in the first condition the flexible prong is disposed within the body portion, and in the second condition the flexible prong is disposed distal of the body portion.

10. The surgical imaging device of claim 1, wherein the at least one flexible prong includes a control line having control leads and power leads, wherein the power leads are configured to transmit power to an imaging sensor of the camera and wherein the control leads are configured to control an intensity of light provided by a light source.

11. The surgical imaging device of claim 1, wherein the at least one leg is configured to rotatably move with respect to the longitudinal axis of the body portion upon an actuation of the at least one control lever.

12. The surgical imaging device of claim 1, further comprising a retraction actuator extending longitudinally through the body portion.

13. The surgical imaging device of claim 12, wherein the retraction actuator is configured to move axially relative to the body portion.

14. The surgical imaging device of claim 1, further comprising at least one memory device for storing data corresponding to operations and functions of the surgical imaging device.

15. The surgical imaging device of claim 14, wherein the data includes at least one of data related to camera movement, adjustment of light intensity, zoom magnification, color, brightness, or focus.

16. The surgical imaging device of claim 14, wherein the data includes at least one of model/serial number identification data, usage data, or image data.

17. The surgical imaging device of claim 16, wherein the model/serial number identification data identifies the surgical imaging device.

18. The surgical imaging device of claim 16, wherein the usage data is collected information related to hours of usage of the surgical imaging device and types of procedures viewed by the surgical imaging device.

19. The surgical imaging device of claim 16, wherein the image data includes at least one of still frames or video clips depicting body cavities.

20. The surgical imaging device of claim 16, wherein the image data are labeled and categorized while the surgical imaging device is in use.
