Abstract

A medical apparatus is described for providing visualization of a surgical site. The medical apparatus includes an electronic display disposed within a display housing, the electronic display configured to produce a two-dimensional image. The medical apparatus includes a display optical system disposed within the display housing, the display optical system comprising a plurality of lens elements disposed along an optical path. The display optical system is configured to receive the two-dimensional image from the electronic display, produce a beam with a cross-section that remains substantially constant along the optical path, and produce a collimated beam exiting the opening in the display housing. The medical apparatus can also include an auxiliary video camera configured to provide an oblique view of a patient on the electronic display without requiring a surgeon to adjust their viewing angle through oculars viewing the electronic display.

Claims

1. A medical apparatus comprising:

a camera having a field of view that can be configured to include a surgical site, wherein the camera is configured to provide a surgical microscope view of the surgical site;

a binocular viewing assembly comprising a housing and a plurality of oculars, the plurality of oculars configured to provide views of at least one display disposed in the housing;

an image processing system configured to receive images acquired by the camera and present the output video images on the at least one display; and

a movement control system configured to move the camera relative to the binocular viewing assembly, wherein the movement control system comprises a control system configured to control at least one electromechanical device operatively coupled to the movement control system, the at least one electromechanical device configured to orient at least one of a translation, pitch-yaw adjustment, and/or working distance adjustment system based on operator input, the at least one electromechanical device configured to orient the camera to a position specified by an operator, wherein the movement control system comprises a control member that is operatively coupled to the movement control system via a gimbal having one or more sensors configured to detect movement of the control member, the one or more sensors in communication with one or more components of the movement control system.

2. The medical apparatus of claim 1, wherein the movement control system comprises a translation system comprising a moveable platform to which the camera is attached, the moveable platform being positioned between the binocular viewing assembly and the camera and being moveable relative to the binocular viewing assembly along at least a first axis and a second axis.

3. The medical apparatus of claim 2, wherein the translation system further comprises the at least one electromechanical device, the at least one electromechanical device operatively coupled to the moveable platform.

4. The medical apparatus of claim 1, wherein the movement control system comprises a pitch-yaw adjustment system comprising the at least one electromechanical device to which the camera is attached, the pitch-yaw adjustment system configured to rotate the camera relative to the binocular viewing assembly around an axis parallel to a first axis and rotate the camera around an axis parallel to a second axis.

5. The medical apparatus of claim 1, wherein the movement control system is attached to the binocular viewing assembly.

6. The medical apparatus of claim 1, wherein coarse control of the movement control system can be achieved without use of the at least one electromechanical device, whereas fine control of the movement control system can be achieved with use of the at least one electromechanical device.

7. The medical apparatus of claim 1, wherein the at least one electromechanical device is programmed to revert the camera back to a pre-set or previous position upon receiving a command from the operator.
