Surgical tool systems and methods
Embodiments of the present disclosure provide a surgical robot system may include an end-effector element configured for controlled movement and positioning and tracking of surgical instruments and objects relative to an image of a patient's anatomical structure. In some embodiments the end-effector may be tracked by surgical robot system and displayed to a user. In some embodiments the end-effector element may be configured to restrict the movement of an instrument assembly in a guide tube. In some embodiments, the end-effector may contain structures to allow for magnetic coupling to a robot arm and/or wireless powering of the end-effector element. In some embodiments, tracking of a target anatomical structure and objects, both in a navigation space and an image space, may be provided by a dynamic reference base located at a position away from the target anatomical structure.
1. A surgical robot system comprising:
a surgical robot base;
a surgical robot arm electronically coupled to the surgical robot base;
an end-effector, coupled to the surgical robot arm, having a guide tube configured to receive an instrument assembly, the instrument assembly containing one or more grooves disposed along a length of the instrument assembly;
an instrument detecting sensor embedded in an upper portion of the guide tube configured to detect a presence of an instrument in the guide tube,
wherein the instrument detecting sensor indicates the presence of the instrument and transmits a sensor signal to the robot base, thereby restricting movement of the robot arm, and
wherein the guide tube is configured to engage at least one of the grooves to restrict rotational movement of the instrument assembly within the guide tube.
2. The surgical robot system of claim 1 , wherein the instrument assembly is configured for the one or more grooves to disengage the guide tube upon the application of a sufficient force to allow rotational movement of the surgical instrument tool assembly.
3. The surgical robot of claim 2 , wherein the guide tube comprises a ball detent to engage the one or more grooves to restrict rotational movement of the instrument assembly.
4. The surgical robot system of claim 3 , wherein the guide tube contains a channel that engages the instrument assembly to restrict rotational movement of the surgical instrument tool assembly.
