Surgical tool systems and method
Medical robot systems, surgical tool assemblies, devices, and methods regarding the same. The medical robot system may include a robot coupled to an end-effector having a guide tube. The robot may be configured for controlled movement and positioning of the end-effector. The system further includes a motor assembly coupled to the robot. The motor assembly may be configured to move the end-effector along one or more of an x-axis, a y-axis, and a z-axis. The surgical instrument is positionable and/or slidable within the guide tube. The surgical instrument includes at least one detectable feature, such as a reflective lens or stripe. A detection device is configured and arranged to detect the at least one detectable feature. The system enables a depth of the surgical instrument in the guide tube to be determined by the at least one detectable feature on the instrument.
1. A medical robot system, comprising:

a surgical instrument positionable within the guide tube, the surgical instrument including at least one detectable feature which is reflective; and
a detection device configured and arranged to detect the reflection of light from the at least one detectable feature,
wherein a depth of the surgical instrument in the guide tube is determined by the at least one detectable feature,
wherein the at least one detectable feature includes at least one reflective marker having a radius of curvature terminating at a substantially flat collar or flange.
2. The medical robot system of claim 1 , wherein the at least one reflective marker comprises at least one reflective lens.
3. The medical robot system of claim 2 , wherein the at least one reflective marker comprises three reflective lenses uniformly and circumferentially spaced from each other around a shaft of the surgical instrument.
4. The medical robot system of claim 2 , wherein the at least one reflective lens comprises three reflective lenses arranged around an outer perimeter of the shaft of the surgical instrument.
5. The medical robot system of claim 2 , wherein the at least one reflective lens is embedded in the handle of the surgical instrument.
6. The medical robot system of claim 2 , wherein the at least one reflective lens includes at least two reflective lenses, and the at least two reflective lenses are attached to the shaft and connected to one another with a housing.
7. The medical robot system of claim 1 , wherein the at least one detectable feature comprises at least one reflective stripe detectable by the detection device.
8. The medical robot system of claim 7 , wherein the at least one reflective stripe is arranged around an outer perimeter of the shaft of the surgical instrument.
9. The medical robot system of claim 7 , wherein the at least one reflective stripe is positioned proximate to the handle of the surgical instrument.
10. The medical robot system of claim 7 , wherein the at least one reflective stripe is formed of a paint containing reflective glass powder.
11. A medical robot system, comprising:
a robot coupled to an end-effector, the robot configured for controlled movement and positioning of the end-effector, the end-effector including a guide tube;
a motor assembly coupled to the robot, the motor assembly being configured to move the end-effector along one or more of an x-axis, a y-axis, and a z-axis;
a surgical instrument positionable within the guide tube, the surgical instrument including at least one detectable feature which is reflective; and
a detection device configured and arranged to detect reflection of light from the at least one detectable feature, wherein a depth of the surgical instrument in the guide tube is determined by the at least one detectable feature and detection of light from the detectable feature by the detection device and detection of position of the guide tube,
wherein the at least one detectable feature comprises a plurality of reflective markers, wherein each of the plurality of reflective markers forms a partial sphere or a semi-sphere and has a radius of curvature terminating at a substantially flat collar or flange.
12. A medical robot system, comprising:
a robot coupled to an end-effector, the robot configured for controlled movement and positioning of the end-effector, the end-effector including a guide tube;
a motor assembly coupled to the robot, the motor assembly being configured to move the end-effector along one or more of an x-axis, a y-axis, and a z-axis; and
a surgical instrument positionable within the guide tube, the surgical instrument including at least one detectable feature;
wherein the at least one detectable feature comprises a plurality of reflective markers, wherein each of the plurality of reflective markers form a semi-sphere, and has a radius of curvature terminating at a substantially flat collar or flange.
