Conventional minimally invasive surgery (MIS) is per­formed through small incisions in the patient’s skin, pre­serving healthy tissue. The surgeon works with long slender instruments, and is separated from the operation area. This arrangement challenges the surgeon’s skills due to lost hand-eye-coordination and missing direct manual con­tact to the operation area. Therefore, many sophisticated procedures still cannot be performed minimally invasive. To overcome the drawbacks of conventional MIS, telepresence and telemanipulation techniques play an im­portant role: In case of minimally invasive robotic surgery (MIRS) the instruments are not directly manipulated any­more. Instead, they are held by specialized robot arms and remotely commanded by the surgeon who comfortably sits at an input console. The surgeon virtually regains direct access to the operating field by having 3D endoscopic sight, force feedback, and restored hand-eye-coordination.

The DLR telesurgery scenario MIROSURGE includes an input (or master) console as well as a teleoperator consisting of 3 surgical robots (MIRO). Usually two MIROs carry surgical instruments (MICA) equipped with miniatur­ized force/torque sensors to capture reaction forces with manipulated tissue. One more MIRO can (automatically) guide a stereo video laparoscope. Both the stereo video stream and the measured forces are displayed to the surgeon at the master console. So users are not limited to see but can also feel what they are doing. An Omega.7 input device is used as force display.

Our ultimate ambition is robot supported surgery on the beating heart. The application of the heart-lung machine would become obsolete for a whole variety of procedures that way. Collaterally, the very traumatizing effects of the heart-lung machine on the patient could be avoided (e.g. blood contact with extrinsic surfaces, inevitable blood clotting attenuation, typical generalized inflammation reaction). Therefore, performance characteristics of the MIROs are designed to follow a stabilized beating heart motion. Additionally, the endoscopic video stream can be stabilized by optical tracking in real time so that a virtually stationary video picture can be consistently presented to the surgeon.
