  • Patent number: 10028734
    Abstract: Exemplary embodiments describe soft robotic actuators for medical use, such as during surgeries and other medical procedures. According to one embodiment, a soft robotic incision retractor is provided. According to another embodiment, a soft robotic body tissue retractor is provided. The incision retractor and body tissue refractor may be used together, for example by using the incision retractor to hold open an incision while the body tissue retractor manipulates biological matter or an object accessible through the incision. Described embodiments offer the ability to conform to a given space, reduced risk of damage to surrounding structures as compared to traditional retractors, the ability to deliver varying amounts of force, the ability to be made from medically safe materials, and the potential for re-use or disposability.

  • Publication number: 20180169869
    Abstract: The present application relates to improvements in support systems for holding one or more robotic actuators, particularly soft robotic actuators. Because soft robotic actuators tend to push away from a base to which they are fixed upon inflation, they must be hold to the base securely. However, this may render it more difficult to remove the actuator from the base (e.g., when the actuator fails, when the actuator and/or base must be cleaned or serviced, or when a user wishes to switch out one style or size of actuator for another). Exemplary embodiments herein relate to improved designs for hubs, including interlocking and quick-release mechanisms that allow the actuator to be held firmly to the hub, but also allow the actuator to be quickly and efficiently released, when needed.

  • Patent number: 9907545
    Abstract: A soft material retractor includes at least two soft actuators, each actuator having at least one pressurizable interior space, wherein the actuator has a first flexible resting state and a second stiffer pressurized state; and a flexible sheet spanning the actuators such that the actuators can be spaced apart from each other by a distance selected to displace a volume of material of a body cavity. The retractor can be uses for holding open wounds or incisions, with trochars, or to displace anatomical features such as organs within a body cavity.

  • Publication number: 20170036355
    Abstract: Exemplary embodiments relate to various improvements in soft robotic actuators, and more specifically the integration of stiff or rigid bodies into soft actuators to provide adjustable gripping behaviors. These actuators may be used as robotic end effectors to, for example, automate material handling processes. According to some embodiments, the actuators may be deployed in combination with a static or dynamic rigid structure, such as a rod. The rigid structure may extend beside or within the actuator. Multiple rigid structures may be deployed on the sides of an actuator, or multiple actuators may be deployed on the sides of a rigid structure. In further embodiments, an array or matrix of actuators may be integrated into a rigid structure, providing a low-profile gripper that can be maneuvered into tight spaces.

  • Publication number: 20160361821
    Abstract: Exemplary embodiments provide modular robotic systems that allow one or more operation parameters of a robotic actuator, or group of actuators, to be dynamically configured or reconfigured. The operation parameters may be, for example, the X, Y, and/or Z position of the actuator or group of actuators with respect to other actuators, the arrangement of the actuator(s) into an array or matrix, the rotation or pitch of an actuator, the distance between actuators, the grip strength or grip surface of an actuator, etc. Accordingly, the same robotic manipulator(s) may be used for multiple purposes in multiple different contexts, manipulators can be swapped out on-the-fly, and robotic systems may be dynamically reconfigured to perform new tasks.

  • Publication number: 20160136820
    Abstract: Exemplary embodiments provide enhancements for soft robotic actuators. In some embodiments, angular adjustment systems are provided for varying an angle between an actuator and the hub, or between two actuators. The angular adjustment system may also be used to vary a relative distance or spacing between actuators. According to further embodiments, rigidizing layers are provided for reinforcing one or more portions of an actuator at one or more locations of relatively high strain. According to further embodiments, force amplification structures are provided for increasing an amount of force applied by an actuator to a target. The force amplification structures may serve to shorten the length of the actuator that is subject to bending upon inflation. According to still further embodiments, gripping pads are provided for customizing an actuator's gripping profile to better conform to the surfaces of items to be gripped.
