Abstract

The various robotic medical devices include robotic devices that are disposed within a body cavity and positioned using a support component disposed through an orifice or opening in the body cavity. Additional embodiments relate to devices having arms coupled to a device body wherein the device has a minimal profile such that the device can be easily inserted through smaller incisions in comparison to other devices without such a small profile. Further embodiments relate to methods of operating the above devices.

Claims20

Dependent claims

A robotic device, comprising:

(a) a device body configured to be positioned at least partially within a body cavity of a patient through an incision, the device body comprising:
(i) a motor housing comprising a first motor and a second motor;
(ii) a gear housing comprising:
(A) a first gear positioned at a distal end of the gear housing, the first gear operably coupled to the first motor;
and
(B) a second gear positioned at a distal end of the gear housing, the second gear operably coupled to the second motor;
(b) a first arm operably coupled to the first gear, wherein the first arm is positioned substantially within a longitudinal cross-section of the device body when the first arm is extended in a straight configuration;
and
(c) a second arm operably coupled to the second gear, wherein the second arm is positioned substantially within the longitudinal cross-section of the device body when the second arm is extended in a straight configuration.

(a) a device body configured to be positioned at least partially within a body cavity of a patient through an incision, the device body comprising:
(i) a motor housing comprising a first motor and a second motor;
(ii) a gear housing comprising:
(A) a first gear positioned at a distal end of the gear housing, the first gear operably coupled to the first motor, wherein the first gear is positioned to rotate around a first axis parallel to a length of the device body, wherein the first gear comprises a first tooth-free portion;
and
(B) a second gear positioned at a distal end of the gear housing, the second gear operably coupled to the second motor, wherein the second gear is positioned to rotate around a second axis parallel to the length of the device body, wherein the second gear comprises a second tooth-free portion;
(b) a first arm operably coupled to the first gear, the first arm comprising a first upper arm and a first forearm, wherein the first arm is positioned substantially within a longitudinal cross-section of the device body when the first arm is extended in a straight configuration such that the first upper arm and the first forearm are collinear;
and
(c) a second arm operably coupled to the second gear, the second arm comprising a second upper arm and a second forearm, wherein the second arm is positioned substantially within the longitudinal cross-section of the device body when the second arm is extended in a straight configuration such that the second upper arm and the second forearm are collinear.
