  • Publication number: 20140276761
    Abstract: An apparatus includes an interface assembly and a shaft assembly. The interface assembly is configured for use with a robotic system and includes a first drive assembly and a mounting plate. The mounting plate includes an opening. The first drive assembly is positioned within the opening such that the first drive assembly is laterally translatable within the opening from a first position to a second position. The shaft assembly is removably coupled with the interface assembly. The shaft assembly comprises an end effector and a first coupling feature. The first drive assembly of the interface assembly actuates the end effector of the shaft assembly. The first coupling feature is longitudinally aligned with the first drive assembly. The first drive assembly engages the first coupling feature of the shaft assembly when the first drive assembly is laterally translated from the first position to the second position.

  • Patent number: 8828046
    Abstract: Methods and devices are provided for controlling movement of an end effector assembly, and in particular for causing mimicking motion between a handle and an end effector assembly. In an exemplary embodiment, a surgical device is provided having a handle or actuator, an elongate shaft, and an end effector assembly coupled to a distal end of the elongate shaft. The handle or actuator is configured such that movement of the handle is mimicked, not mirrored, by the end effector assembly. The mimicking motion can be achieved using various techniques, but in an exemplary embodiment the handle is located distal to an input joint, and motion is transferred to the end effector assembly through an output joint at a distal end of the elongate shaft. The motion is preferably transferred using a mechanical transmission coupled between the input and output joints.

  • Publication number: 20140194914
    Abstract: A surgical instrument is provided that can comprise and end effector including two jaws and a cutting member configured to move between the jaws. In at least one embodiment, one or both of the jaws may be flexible, such that a jaw is configured to flex when gripping tissue. Further, at least one of the jaws may include a thin cross-sectional area such that the jaw flexes when gripping tissue. Additionally, in at least one embodiment, one or more compression elements may extend from the cutting member and may be configured to cause the jaws to close when the cutting member is advanced. The compression elements may comprise a roller and/or a low-friction material. Moreover, in at least one embodiment, one or both of the jaws may be precurved, away from the cutting member's longitudinal axis. Accordingly, in various embodiments, the overall force required to advance the cutting member and/or close the jaws may be reduced.

  • Patent number: 8623044
    Abstract: Various embodiments are directed to a surgical instrument comprising a handle, a shaft coupled to the handle and extending along a longitudinal axis, an end effector, and a cable. The end effector may comprise a first jaw member, a second jaw member and a reciprocating member. The cable may extend distally from the handle through the shaft to a first pulley of the first jaw member. From the first pulley, the cable may extend proximally to the reciprocating member, such that proximally directed motion of the cable exerts a distally directed force on the reciprocating member.

  • Patent number: 8617203
    Abstract: Surgical devices are disclosed herein that generally include an intracorporeal elbow joint to facilitate translational movement of an end effector while allowing a body portion of the surgical device and a trocar or working channel through which the device is inserted to be maintained in a fixed angular orientation relative to the patient. This allows a plurality of such devices to be used effectively with a single incision or access device. Such devices also generally provide end effector movement with six degrees of freedom, while maintaining a mechanical linkage between the user and the end effector and while mimicking and/or mirroring natural user movement. Various methods related to such devices are also disclosed.

  • Publication number: 20130085510
    Abstract: The systems and methods disclosed herein generally involve a robotically-assisted surgical system in which a platform for supporting a patient is physically and operatively coupled to a surgical robot and an associated controller. As a result, the position of the patient can be controlled remotely using the robot, and the controller can have an awareness of the position and orientation of the patient with respect to the operating room and with respect to various components of the robot. Such systems can thus maintain a fixed frame of reference between the patient and one or more end effectors of the surgical robot, eliminating the need for recalibration of the system due to patient movement.

  • Publication number: 20130085341
    Abstract: Methods and devices are provided for manipulating tissue in a body cavity, i.e., in vivo. In general, the methods and devices allow an end effector to engage tissue, be detached from a shaft used to control the end effector to engage the tissue, and then be moved to another location in the body cavity by a separate component, such as an external control unit. In some embodiments the end effector can include one or more deployable hooks that allow the end effector to remain at a surgical site independent of any shafts or external control units. Still further, in other embodiments the end effector can include a transverse bore to allow a second shaft to connect to the end effector to manipulate the tissue. Additional exemplary devices, kits, and methods related to manipulating tissue in vivo are also provided.
