First Claim
1. A surgical robot system comprising:
- a display;
a housing;
an arm; and
a guided surgical tool assembly coupled to the arm, the guided surgical tool assembly comprising;
a rigid guide tube disposed in the guided surgical tool assembly, wherein the rigid guide tube is a single hollow structure including at least one sensor disposed inside the single hollow structure, wherein the rigid guide tube is configured to removably receive one of a plurality of surgical instruments associated with spinal surgery;
a surgical instrument configured to be received within the single hollow structure containing the at least one sensor, the surgical instrument including at least one detectable feature extending longitudinally along the surgical instrument; and
wherein the at least one sensor is configured and arranged to couple with the at least one detectable feature when the surgical instrument is inside the single hollow structure to determine a position of the surgical instrument within the guide tube,wherein the surgical robot system is configured to calibrate a targeting fixture to a medical image received by the surgical robot system in order track movement of the surgical instrument, receive data indicative of an intended trajectory associated with the medical image, and move the arm and guide surgical tool in accordance with the intended trajectorywherein the detectable feature includes at least one longitudinal magnetic strip and at least one radial magnetic strip, wherein the at least one longitudinal magnetic strip extends the entire length of the guide tube and the radial magnetic strip is positioned proximal to a first opening and extending the entire circumference of the guide tube.

Abstract
Embodiments of the invention provide a guided surgical tool assembly with a guide tube including a sensor, a surgical instrument including a detectable feature moveable within the guide tube, and the sensor capable of detecting the detectable feature when the surgical instrument is inserted in the guide tube. Some embodiments include a sensor pad, a guide stop coupled to the surgical instrument, a plunger mechanism including a compressible spring mechanism coupled to the guide tube, and a wiper capable of being sensed by the sensor pad. Some embodiments include a guided surgical tool assembly system comprising a tool sensor system including a processor and at least one data input/output interface. Some embodiments include a medical robot system with a guided surgical tool assembly and including a robot coupled to an effectuator element configured for controlled movement and positioning along one or more of an x-axis, a y-axis, and a z-axis.
