  • Publication number: 20190000580
    Abstract: A robotic surgical system may include an actuator including a plurality of linearly displaceable drive members, where at least one drive member actuates at least one degree of freedom of a surgical instrument, and a sterile adapter interposed between the actuator and the surgical instrument. The sterile adapter includes a flexible barrier and a plurality of extensible covers integrally formed with the flexible barrier, and the plurality of extensible covers are arranged to receive the plurality of drive members. In some variations, the system may include an interlocked arrangement coupling the actuator and the surgical instrument across the sterile adapter, the interlocked arrangement urging the actuator and the surgical instrument together when the actuator actuates the at least one degree of freedom of the surgical instrument.

  • Patent number: 10022193
    Abstract: A surgical system (200) includes a surgical instrument (260) that is sensitive to backlash that would adversely affect the transmission of controlled torque and position to the surgical instrument. The surgical instrument (260) is coupled to motors in a surgical instrument manipulator assembly (240) via a mechanical interface. The combination of the mechanical interface and surgical instrument manipulator assembly (240) have low backlash, e.g., less than 0.7 degrees. The backlash is controlled in the surgical instrument manipulator assembly (240). From the drive output disk (545) in the surgical instrument manipulator assembly to the driven disk (964) of the surgical instrument, the mechanical interface has zero backlash for torque levels used in surgical procedures.

  • Patent number: 10011018
    Abstract: A surgical system uses a single entry port in a wide variety of surgeries. To insert multiple surgical instruments into a patient through a single entry port requires that the shaft of at least one of the surgical instruments be bent between the base of the surgical instrument and the point where the shaft contacts a channel in an entry guide. Each surgical instrument is positioned by an instrument manipulator positioning system so that when the shaft is inserted in a channel of the entry guide, any bending of the shaft does not damage the surgical instrument and does not inhibit proper operation of the surgical instrument.

  • Patent number: 8690919
    Abstract: A surgical spacer comprising first and second hollow support members, a flexible container, and a compressible material disposed in the container is disclosed. The first and second support members each have an exterior and an interior cavity. The exteriors of the first and second support members are affixed together and the interior cavities of the first and second support members are connected via a connecting opening. The container is disposed in the interior cavities and extends through the connecting opening. In addition, the container is substantially impermeable to the compressible material. The first and second support members are more rigid than the flexible container. A combination of the first and second support members controls the shape of the flexible container, with the compressible material disposed therein, in response to a compressive load applied to an exterior of the spacer.

  • Patent number: 8425601
    Abstract: The present application is directed to methods and devices that provide for asymmetrical movement of vertebral members. In one embodiment, first and second anchors connect the rod to the vertebral members. The rod may be fixedly connected to the first anchor, and movably connected to the second anchor. A limiting device may be positioned on one or both sides of the second anchor. The limiting device or devices control an extent of movement between the rod and the second anchor during vertebral motion. In one embodiment, the device controls an amount of flexion and extension of the vertebral members.

  • Patent number: 8425561
    Abstract: An interspinous process brace is disclosed and can include a superior component and an inferior component. The superior component can include a superior spinous process bracket that can engage a superior spinous process. The inferior component can include an inferior spinous process bracket that can engage an inferior spinous process. Further, the interspinous process brace can be moved between a bent configuration and a straight configuration. In the bent configuration, an overall height of the interspinous process brace can be minimized to facilitate installation between the superior spinous process and the inferior spinous process.

  • Patent number: 8348977
    Abstract: Devices and methods for attaching a support to the sacrum. One device may include first and second anchors that mount to the sacrum, and first and second lateral extensions coupled to the anchors to secure the device to the sacrum. A bearing face having a width is positioned between the lateral extensions. The face may have a height in an anterior-posterior direction greater than the spinous process of the sacrum. Further, the bearing face may be oriented in a superior direction when the device is mounted to the sacrum. An implant may be supported by the device to space the sacrum and L5 vertebra. The implant may be an interspinous device and positioned between the L5 spinous process and the bearing face. The implant is supported at least in part by the bearing face.

  • Patent number: 8262698
    Abstract: An interspinous implant includes a spacer having an upwardly facing concave saddle and a downwardly facing concave saddle. The lateral sides of the implant are pulled inward to force the saddles vertically away from each other, thereby increasing the effective height of the implant. In one version, a strap extends circumferentially around the anterior and posterior surfaces of the spacer, such that tightening the strap causes the saddles to move away from each other. In another version, the spacer includes a first outwardly facing convex segment disposed on a first lateral side of the saddles and a second outwardly facing convex segment disposed on a second lateral side of the saddles. A rod extends between the first and second convex segments and is fixed to the first convex segment and movable relative to the second convex segment.
