Abstract
A tool for creating an incision at a surgical site includes a body for use with a robotic end effector having a proximal end and a distal end, and a blade positioned at the distal end of the body, the blade having a proximal end and a distal end, the blade having a cutting edge defining a first portion extending outwardly from or adjacent to the proximal end to a maximum width and a second portion extending inwardly from the maximum width to a sharp distal tip.
Claims19
A system comprising:
- a surgical robot including a robotic arm for maintaining a trajectory relative to a surgical site;
- a tool for creating an incision at the surgical site, the tool including:
- a body having a proximal body end, a distal body end, and a central portion between the proximal body end and the distal body end;
- and
- a blade positioned at the distal body end of the body, the blade having a proximal blade end, a distal blade end, and a cutting edge defining:
- a first portion extending outwardly from or adjacent to the proximal blade end to a maximum width, and
- a second portion extending inwardly from the maximum width to a sharp distal tip;
- and
- a guide tube operatively attached to the robotic arm and defining:
- a bore for supporting the central portion of the body of the tool along an axis, and
- a longitudinal slot formed in communication with the bore and shaped for receiving the blade of the tool as the blade passes through the guide tube to bring the central portion of the body into engagement with the bore.
