Telemanipulation in Minimally Invasive Surgery
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 (DLR MICA), the third MIRO (automatically) guides a stereo video laparoscope. The stereo video stream as well as information about the system state – e.g. the currently used instruments or workspace limits – is displayed to the surgeon at the master console. While operating the system the surgeon is not limited to seeing but can via force feedback also feel workspace limits or collisions of the instruments in the hand controllers.
Our current research focus is the advancement from the existing research platform for robotic telesurgery to a cognitive robotic assistance, which provides the surgeon depending on the situation all necessary information in an optimal manner and is able to perform small tasks semi-autonomously.
