Abstract
Devices, systems, and methods for aiding insertion of a surgical implant by providing a threaded guide tube configured to engage a threaded surgical instrument such that an end-effector of a robot may provide force to drive the surgical implant into a patient. In addition, devices, systems, and methods relating to a dilator system for use with a robotic system that allows independent and separate control of tools within the dilator system.
Claims8
A system for independently advancing multiple components of a tool into bone, comprising:
- a center shank configured to advance a first component of the tool into a bone, wherein the center shank is threaded;
- a rod disposed around the center shank and configured to advance a second component of the tool in the bone, wherein the rod is configured to move independently from the center shank,
- wherein the system is mounted to a surgical robot, the first component is a center pin, and the second component is an inner dilator,
- wherein the center pin is configured to have a pointy distal end to engage the bone, and wherein the rod is corkscrew shaped and helically disposed around the center shank.
