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 invasively. 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 a master 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 a master console with a 3D-display and two haptic devices as well as a teleoperator consisting of three MIRO robot arms. Usually two MIROs carry surgical instruments (MICA) equipped with miniatur­ized force/torque sensors to capture reaction forces with manipulated tissue. The third MIRO can (automatically) guide a stereo video laparoscope. The stereo video stream as well as the measured forces are displayed to the surgeon at the master console. Therefore the surgeon is not limited to seeing but can via force feedback in the input devices also feel what he is doing.

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.
