Apparatus and systems for precise guidance of surgical tools
First Claim
1. A surgical system for performing a robotically assisted medical procedure on a patient, said system comprising:
- a computing system;
a robot arm;
an end-effector attached to the robot arm, wherein the end-effector is configured to releasably hold a plurality of surgical instruments;
a control interface configured to receive commands and to control operation of the robot arm, wherein the control interface is in electronic communication with the computing system;
an actuator, in electronic communication with the control interface, configured to move the robot arm;
a patient marker adapted to be coupled to a bone of the patient; and
a tracking detector configured to capture a position of the surgical instrument held by the end-effector in relation to the patient based on the patient marker,wherein the computing system is configured to perform a registration to spatially align the end-effector, the patient and a desired trajectory of the end-effector based on the patient marker, and to maintain the spatial alignment without performing re-registration of the end-effector position when the surgical instrument held by the end-effector is removed and replaced with a different one of the surgical instruments.

Abstract
Described herein are systems, apparatus, and methods for precise placement and guidance of tools during a surgical procedure, particularly a spinal surgical procedure. The system features a portable robot arm with end effector for precise positioning of a surgical tool. The system requires only minimal training by surgeons/operators, is intuitive to use, and has a small footprint with significantly reduced obstruction of the operating table. The system works with existing, standard surgical tools, does not required increased surgical time or preparatory time, and safely provides the enhanced precision achievable by robotic-assisted systems.

18. A surgical system for performing a robotically assisted medical procedure on a patient, said system comprising:
-
a computing system; a robot arm; a plurality of surgical instruments; an end-effector attached to the robot arm and adapted to releasably hold the plurality of surgical instruments; an actuator configured to move the robot arm; a control interface coupled to the computing system and the actuator, the control interface configured to receive commands from the computing system and to control operation of the robot arm via the actuator; a patient marker adapted to be attached to a bone of the patient; and a tracking detector configured to capture a position of the surgical instrument held by the end-effector in relation to the patient based on the patient marker, the tracking detector further configured to identify the plurality of surgical instruments; wherein the computing system is configured to perform a registration to spatially align the end-effector relative to the patient based on the patient marker attached to the patient, and to maintain the spatial alignment without performing re-registration of the end-effector position when the surgical instrument held by the end-effector is removed and replaced with a different one of the surgical instruments. - View Dependent Claims (19, 20)
