  • Publication number: 20220193451
    Abstract: Described herein are multi-leaf collimators that comprise leaf drive mechanisms. The leaf drive mechanisms can be used in binary multi-leaf collimators used in emission-guided radiation therapy. One variation of a multi-leaf collimator comprises a pneumatics-based leaf drive mechanism. Another variation of a multi-leaf collimator comprises a spring-based leaf drive mechanism having a spring resonator.

  • Publication number: 20080183038
    Abstract: A biological navigation device that can be attached or integrated with an elongated element, such as a colonoscope, is disclosed. The device can be used for navigation through a biological lumen. The device can have an everting tube controllably tearable substantially in the direction of the long axis of the device. The elongated element can be deployed through a channel formed in the inner virtual space of the channel extending along the long axis.

  • Publication number: 20080071290
    Abstract: A surgical instrument extends through a guide tube and exits at an intermediate position of the guide tube. The instrument includes a parallel motion mechanism that changes the position of a distal end of the surgical instrument without changing the orientation of the distal end. An image capture component is at the distal end of the guide tube, and a joint allows the image capture component to move while the intermediate position remains stationary. The configuration allows a cross section of the guide tube to be oblong. In some aspects, a joint for the image capture component is placed between exit ports for surgical instruments, which allows the guide tube cross section to be further reduced.

  • Publication number: 20080071291
    Abstract: Two surgical instruments are extended through a single guide tube in a telemanipulation system. Telemanipulation actuators move each of the instruments in all six Cartesian degrees of freedom independently of any guide tube movement.

  • Publication number: 20080071289
    Abstract: Two surgical instruments are inserted through a guide tube. The surgical instruments exit at an intermediate position of the guide tube and are oriented to be substantially parallel to the guide tube's longitudinal axis as they exit. A stereoscopic image capture component is on the guide tube between the intermediate position and the guide tube's distal end. The image capture component's field of view is generally perpendicular to the guide tube's longitudinal axis. The surgical instruments and the guide tube are telemanipulatively controlled.

  • Publication number: 20080065097
    Abstract: A minimally invasive surgical instrument includes a U-turn mechanism that transmits actuating forces around a U-turn. The U-turn mechanism is coupled between segments of the instrument and has a bend radius that is smaller than flexible arms having a similar cross section diameter. The actuating forces transmitted by the U-turn mechanism are used to move distal components of the instrument, such as an end effector and a wrist mechanism.

The surgical instrument exits at an intermediate position of the guide tube and is oriented to be substantially parallel to the guide tube's longitudinal axis as it exits. A stereoscopic image capture component is on the guide tube between the intermediate position and the guide tubers distal end. The image capture component's field of view is generally perpendicular to the guide tube's longitudinal axis. The guide tube is jointed to allow the image capture component to be moved. The surgical instruments and the guide tube are telemanipulatively controlled.
