Abstract

The disclosed technology relates to robotic surgical systems for improving surgical procedures. In certain embodiments, the disclosed technology relates to robotic surgical systems for use in osteotomy procedures in which bone is cut to shorten, lengthen, or change alignment of a bone structure. The osteotome, an instrument for removing parts of the vertabra, is guided by the surgical instrument guide which is held by the robot. In certain embodiments, the robot moves only in the “locked” plane (one of the two which create the wedge—i.e., the portion of the bone resected during the osteotomy). In certain embodiments, the robot shall prevent the osteotome (or other surgical instrument) from getting too deep/beyond the tip of the wedge. In certain embodiments, the robotic surgical system is integrated with neuromonitoring to prevent damage to the nervous system.

Claims8

Dependent claims

A robotic surgical system for use in a surgical procedure performed on a patient, the system comprising:

a robotic arm comprising an end-effector;
an actuator for controlled movement of the robotic arm and positioning of the end effector, thereby controlling the trajectory and/or insertion depth of a surgical instrument in a guide affixed to the end effector;
a neuromonitoring module for implementing real-time neuromonitoring during a surgical procedure;
and
a processor and a memory storing instructions thereon, wherein the instructions, when executed, cause the processor to:
receive, by the neuromonitoring module, a trigger based on a neurological response of a portion of a nerve structure of the patient that is measured by a neuromonitoring system;
and
move a surgical instrument guided by the robotic surgical system away from upon receipt of the trigger
wherein the surgical instrument guide is integrated with the neuromonitoring module,
wherein the neuromonitoring module is configured to control the robotic system in response to an external signal.
