  • Patent number: 11793394
    Abstract: A steerable endoscope system includes a continuum manipulator, a plurality of syringes, and a steerable tip. The continuum manipulator includes a plurality of spaced discs and a plurality of backbones each extending through all discs. A bending movement of the continuum manipulator changes a varying linear displacement of each backbone. Each backbone is further coupled to a different one of the syringes such that the linear displacement of each backbone pushes or pulls a piston of the corresponding syringe by a varying amount. The steerable tip includes a plurality of bellows each pneumatically coupled to a different syringe such that movement of the piston of a syringe causes the corresponding bellow to inflate or deflate. Because the distal end of each bellow is fixedly coupled to the same end effector, variations in the amount of inflation or deflation on each bellow causes a bending of the steerable tip.

  • Patent number: 11122965
    Abstract: Systems and methods are presented for localization of a capsule based on magnetic fields. The capsule is positioned in a magnetic field generated by a first magnet and an electromagnetic coil is operated to generate a sinusoidal magnetic field with a magnetic moment orthogonal to the magnetic moment of the first magnet. An average signal measurement calculated for each magnetic field sensor is defined as the magnetic field applied to the magnetic field sensor by the first magnet and used as an offset to determine the magnetic field applied by the electromagnetic coil. The pose of the capsule is then determined based at least in part on a combination of magnetic field signals applied by the electromagnetic coil to each of the magnetic field sensors.

  • Patent number: 10485409
    Abstract: Systems and methods are described for determining an orientation and position of a capsule inserted into the body of a patient. A magnetic field is applied to an area of the patient where the capsule is located. Sensor data, including inertial data from an inertial sensor and magnetic field data indicative of the applied magnetic field as detected by at least one magnetic field sensor, is wirelessly received from the capsule. An orientation angle of the capsule is determined based at least in part on the inertial data.

  • Patent number: 9737364
    Abstract: A method of actuating a surgical device is described. A surgical tool is inserted into a body cavity of a patient through a natural orifice. A distal end of an actuation tool is inserted through a surgical access port in the body of the patient. The distal end of the actuation tool is positioned proximal to an external wall of the body cavity opposite the surgical tool. A magnetic coupling is established between the distal end of the actuation tool and the surgical tool. When the magnetic coupling is established, distal end of the actuation tool is located at the external wall of the body cavity and the surgical tool is located at the internal wall of the body cavity. The surgical tool is manipulated using the actuation tool through the magnetic coupling.

  • Patent number: 9579163
    Abstract: Robotic platform for mini-invasive surgery comprising robotic arms (4a, 4b) suitable to be placed in the body of a patient, introduced through a single access port, which are an extension of external robotic manipulators (19). The continuity between external (1) and internal (4a, 4b) robotic arms is guaranteed by means of a trans-abdominal magnetic connection (6) between the internal robotic arm integral with the external one. The trans-abdominal magnetic coupling not only guarantees a stable anchoring, but most of all it transfers degrees of freedom to the internal robotic arms, inducing the motion of internal magnets by means of the automatized motion of external magnets. It is also possible to reposition the internal robotic arms without requiring having to additionally perform incisions on the abdomen. Using the external robotic arms allows translating the internal ones on the entire abdomen thus providing a working space not bound to the point of insertion and theoretically unlimited.
