Surgical robotic automation with tracking markers
Devices, Systems, and Methods for detecting a 3-dimensional position of an object, and surgical automation involving the same. The surgical robot system may include a robot having a robot base, a robot arm coupled to the robot base, and an end-effector coupled to the robot arm. The end-effector, surgical instruments, the patient, and/or other objects to be tracked include active and/or passive tracking markers. Cameras, such as stereophotogrammetric infrared cameras, are able to detect the tracking markers, and the robot determines a 3-dimensional position of the object from the tracking markers.

wherein the robot is configured to control movement of the end-effector to perform a given surgical procedure, wherein the robot is configured to automatically move the robot arm to a location based on an indication by a user on an image of a patient's anatomy on a display, and
wherein the expandable scalpel includes an inner shaft and outer shaft coupled to one another, the inner shaft includes a cutting assembly having a first element and a second cutting element pivotably coupled to the inner shaft, wherein the expandable scalpel is sized to be received through a proximal end of the guide tube such that a distal end of the expandable scalpel passes through the guide tube and extends past a distal end of the guide tube;
wherein the expandable scalpel includes a plurality of pivot points configured to allow movement of the cutting assembly, and
wherein the expandable scalpel includes active or passive markers for independent navigation and tracking of the expandable scalpel in three-dimensions.
10. The system of claim 9 , wherein inner shaft and the outer shaft are fixed to one another through a pin.
11. The system of claim 9 , where in the inner shaft includes a proximal portion and a distal portion, the proximal portion includes a handle assembly.
12. The system of claim 11 , wherein the proximal portion of the inner shaft includes a biasing element.
13. The system of claim 9 , wherein in a first position the cutting assembly has a width that is smaller than width of the end effector and in a second position the cutting assembly has a width that is greater that the width of the end effector.
14. The system of claim 9 , wherein when a forced is applied downward on the handle assembly, the first cutting element and the second cutting element pivot outward causing the first cutting element and the second cutting element to expand.
15. The system of claim 9 , wherein the expandable scalpel includes optical markers for navigating the expandable scalpel with reference to the end effector and a patient.
