Abstract
The invention relates generally to robotically controlled systems, such as medical robotic systems. In one variation, a robotic catheter system is configured with a sterile barrier capable for transmitting a rotary force from a drive system on one side of the barrier to surgical tool on the other side of the sterile barrier for performing minimally invasive diagnostic and therapeutic procedures. Modularized drive systems for robotics are also disclosed herein.
Claims16
A surgical barrier for use with a medical positioning system having a medical tool, where the medical positioning system includes at least a driver mechanism to affect a position of the medical tool, the surgical barrier comprising:
- a sterilizable drape portion, comprising a surgical side and a working side, wherein the working side is adapted to contact a portion of the medical positioning system, while a sterile surgical field is preserved on the surgical side;
- at least one flexible cup in the drape portion, wherein a working side of the at least one flexible cup is configured to couple to a portion of the driver mechanism, wherein at least a portion of a surgical side of the at least one flexible cup couples to the medical tool, and wherein the at least one flexible cup is configured to deform and transfer motion from the driver mechanism of the medical positioning system to the medical tool;
- and
- a flexure area in the sterilizable drape portion, wherein the flexure area accommodates movement or rotation of the at least one flexible cup and the driver mechanism.
A surgical barrier for use with a medical positioning system having a medical tool, where the medical positioning system includes at least a driver mechanism to affect a position of the medical tool, the surgical barrier comprising:
- a sterilizable drape portion, comprising a surgical side and a working side, wherein the working side is adapted to contact a portion of the medical positioning system, while a sterile surgical field is preserved on the surgical side;
- at least one flexible encasement in the drape portion, wherein a working side of the at least one flexible encasement is coupled to the driver mechanism, wherein at least a portion of a surgical side of the at least one flexible encasement is coupled to the medical tool, and wherein the at least one flexible encasement is configured to deform and transfer motion from the driver mechanism of the medical positioning system to the medical tool;
- and
- a flexure area in the sterilizable drape portion, wherein the flexure area accommodates movement or rotation of the at least one flexible encasement and the driver mechanism.
