Sterile drape for robotic drive

A method of applying a sterile barrier on a robotic drive having a drive body and a first drive module moving along a longitudinal axis of a drive the drive body, the method comprising:

• providing a robotic drive body;
• providing a support arm supporting the robotic drive body;
• providing a first drive module configured to move along a longitudinal axis of the robotic drive body;
• providing a second drive module configured to move along the longitudinal axis of the robotic drive body, the second drive module being separate from the first drive module;
• and
• providing a sterile barrier including a first resilient member having a first free edge proximate the longitudinal axis,
• securing the sterile barrier to the drive body and aligning the first free edge of the resilient member along the longitudinal axis of the drive body adjacent a first drive module, the first free edge adjacent the first drive module being resiliently biased away from and returned to the longitudinal axis as the first drive module moves along the longitudinal axis about the robotic drive.

A sterile barrier for a robotic drive comprising a first drive module configured to move along a longitudinal axis of a drive body, the sterile barrier comprising:

• a first resilient member having a first free edge proximate the longitudinal axis, the first free edge adjacent the first drive module is resiliently biased away from and returned to the longitudinal axis as the first drive module moves along the longitudinal axis, and
• a second resilient member having a second free edge proximate the longitudinal axis, wherein the second free edge adjacent the first drive module being resiliently biased away from and returned to the longitudinal axis as the first drive module moves along the longitudinal axis between the first resilient member and the second resilient member,
• wherein the robotic drive comprises a second drive module moving along the longitudinal axis of the drive body independently of the first drive module;
• wherein the first free edge and the second free edge, of the sterile barrier, adjacent the second drive module resiliently move away from the longitudinal axis and back to the longitudinal axis as the second drive module moves along the longitudinal axis.
