Remote robotic assisted surgery system tested aboard the International Space Station
maxon’s components are integral in the spaceMIRA surgical robot, which recently completed its first demo test surgeries in zero gravity on the International Space Station. Six doctors took turns controlling the device from Earth.
The spaceMIRA, developed by Virtual Incision and researchers at the University of Nebraska, is a compact, lightweight surgical robot sent to the ISS on a SpaceX Falcon 9 rocket from Cape Canaveral in January. From Lincoln, Nebraska, 250 miles below the ISS orbit, six surgeons took turns performing remote testing of the unit by manipulating and cutting a rubber band type material that simulated actual tissue.
spaceMIRA, is a specially designed space-focused iteration of Virtual Incision's MIRA, the world's first miniaturized robotic-assisted surgery (miniRAS) system to be commercially available in the US. Similar to MIRA, its small and sleek design aims to offer the capabilities of robotic-assisted surgery (RAS) in a compact and convenient form factor that make it easier to transport and store the device. The modifications of spaceMIRA enabled pre-programmed and long-distance remote surgery capabilities for the experiment on the International Space Station (ISS).
Virtual Incision worked with maxon during the design of both the terrestrial version of MIRA and spaceMIRA. The robotic-assisted surgery (RAS) system incorporates the first-ever articulating camera. MIRA and spaceMIRA gain its strength in a small size by placing maxon's motors inside the arms of the minibot. This structure allows the device to tackle a complex multi-quadrant procedure like colon resection across a broad range of patient types. The rigid, non-snake-like arms with internally mounted motors deliver the required strength to perform the surgeries while enabling triangulation of the camera and instruments.
The maxon components had to meet a number of demanding specifications due to the high speeds and torques required. Through their partnership with maxon, Virtual Incision was able to increase the efficiency of their system and maximize the deliverable output power for each joint. In addition to maxon's complete line of motors and accessories, the company was able to create precision subassemblies specifically for MIRA. maxon's team of engineers were helpful from conception and design to manufacturing of spaceMIRA's subsystem. Virtual Incision developed all of the accompanying hardware, firmware, and software in-house to optimize miniaturization and device performance characteristics.
RAS systems offer multiple benefits to patients, including fewer site infections, less pain, less blood loss, smaller scars, shorter hospital stays, and quicker recoveries. The test procedure on the ISS supports the feasibility of long-distance surgeries. MIRA is easy to clean and sterilize between uses and does not need to be draped like larger main frame, boom-and-pedestal based units. Ultimately, MIRA is the smallest soft tissue robotic assisted surgery system on the market. It offers significant strength for its size and high output force and it is designed to enable quick setup in any operating room, whether in a large hospital, outpatient facility, or small rural surgical center.
Featured Product
3D Vision: Ensenso B now also available as a mono version!
This compact 3D camera series combines a very short working distance, a large field of view and a high depth of field - perfect for bin picking applications. With its ability to capture multiple objects over a large area, it can help robots empty containers more efficiently. Now available from IDS Imaging Development Systems. In the color version of the Ensenso B, the stereo system is equipped with two RGB image sensors. This saves additional sensors and reduces installation space and hardware costs. Now, you can also choose your model to be equipped with two 5 MP mono sensors, achieving impressively high spatial precision. With enhanced sharpness and accuracy, you can tackle applications where absolute precision is essential. The great strength of the Ensenso B lies in the very precise detection of objects at close range. It offers a wide field of view and an impressively high depth of field. This means that the area in which an object is in focus is unusually large. At a distance of 30 centimetres between the camera and the object, the Z-accuracy is approx. 0.1 millimetres. The maximum working distance is 2 meters. This 3D camera series complies with protection class IP65/67 and is ideal for use in industrial environments.
