Abstract

A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the images generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as at least partially transparent. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

Claims

1. A medical apparatus comprising:

a retractor configured to hold open an incision to provide a pathway for access of surgical tools to a surgical site;

a plurality of cameras configured to acquire video images of the surgical site, at least one of the plurality of cameras being disposed on the retractor, the at least one of the plurality of cameras configured to be tilted downward relative to the retractor and configured to acquire video images within the opening provided by the retractor;

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

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

a viewing articulating arm, the viewing assembly disposed on the viewing articulating arm, the viewing articulating arm configured to adjust a position of the viewing assembly;

a support, the viewing articulating arm attached to the support such that the viewing articulating arm can move relative to the support;

a second articulating arm, the auxiliary camera disposed on the second articulating arm so that the auxiliary camera can be positioned independently of the viewing assembly, the second articulating arm configured to provide isocenter positioning of the auxiliary camera; and

an image processing system in communication with the plurality of cameras, the auxiliary camera, and the at least one display, the image processing system comprising at least one physical processor,

wherein the image processing system is configured to;

receive video images acquired by the plurality of cameras,

receive video images acquired by the auxiliary camera,

provide output video images based on the received video images,

present the output video images on the at least one display so that the output video images are viewable in said viewing assembly, and

switch between displaying the output video images comprising at least one output video image from the auxiliary camera and at least one output video image from the at least one camera disposed on the retractor,

wherein the viewing assembly does not provide a view of the surgical site via an optical pathway that passes through the housing.

2. The medical apparatus of claim 1, wherein the auxiliary camera comprises a 3-D camera and the at least one display is configured to provide 3-D viewing of images from the 3-D cameras.

3. The medical apparatus of claim 1, wherein the auxiliary camera comprises an optical assembly having an adjustable working distance of between about 15 cm and about 45 cm.

4. The medical apparatus of claim 3, wherein the optical assembly has a variable magnification of between about −

0.5× and

about 10×

.

5. The medical apparatus of claim 3, wherein the auxiliary camera is configured to provide views of the surgical site from a distance further than the cameras disposed on the retractor.

6. The medical apparatus of claim 1, wherein the retractor comprises at least one retractor blade, and wherein the at least one of the plurality of cameras is configured to be tilted downward relative to the at least one retractor blade.

7. The medical apparatus of claim 1, wherein the viewing assembly further comprises a plurality of oculars configured to provide the views of the at least one display disposed in the housing.
