20100166496 | DEVICE THAT CAN BE ASSEMBLED BY COUPLING - A device can be assembled by a coupling. The device includes first and second body members and positioning structure. The first and second body members are designed to be coupled relative to each other. The positioning structure is designed to provide an interface between the first and second body members, and to position the first and second body members relative to each other via first, second, and third contact areas. The first, second, and third contact areas are each substantially linear and are collectively configured to receive loads, and to limit positioning of the first and second body members relative to each other with regard to five degrees of freedom. A fourth contact area between the first and second body members is designed to limit positioning of the first and second body members relative to each other in a sixth degree of freedom, in a first translational direction. | 07-01-2010 |
20100168723 | END EFFECTOR WITH RELEASE ACTUATOR - An end effector is disclosed that includes a tool including a drive configured to be coupled to and drive an engaging member for engaging a workpiece and a release member configured to be displaced to permit decoupling of the engaging member from the drive. The end effector also includes a housing configured to receive at least a portion of the tool and a release actuator disposed at least partially outside of the housing and coupled to the housing to permit movement between a first position and a second position to displace the release member to permit decoupling of the engaging member from the drive. | 07-01-2010 |
20110315413 | Kit-Of Parts for Multi-Functional Tool, Drive Unit, and Operating Members - A multi-functional tool is provided including a drive unit and one or more operating members. Each operating member includes a plurality of coupling features configured to be coupled with a plurality of drive unit coupling features. The interaction between the drive unit coupling features and the coupling features of the operating member determines the type of planar motion in which the operating member moves relative to the drive unit when the multi-functional tool is in operation. This motion may be orbital, sagittal, or reciprocal. The motion provided by the drive unit to an operating member may be changed by replacing one operating member coupled to the drive unit with another, different operating member. In some exemplary embodiments, at least three operating member are provided and each operating member is configured to be moved with one of orbital, sagittal, or reciprocal motion. | 12-29-2011 |
20130172903 | Surgical Tool for Robotic Arm with Rotating Handle - A surgical tool is disclosed that may be rotatably mounted to a surgical robotic arm. The surgical tool is rotatable about a first axis that is at least substantially vertical when the robotic arm is in a horizontal position. The surgical tool includes a housing that is coupled to the arm and rotatable about the first axis. The housing is at least substantially cylindrical and defines a second axis that is at least substantially perpendicular to the first axis. The tool also includes a handle that includes a grip that is coupled to a sleeve. The sleeve rotatably accommodates at least part of the housing. As a result, the handle and sleeve may be rotated about the second axis while the housing remains fixed with respect to the second axis. | 07-04-2013 |
20140180290 | SYSTEMS AND METHODS FOR HAPTIC CONTROL OF A SURGICAL TOOL - A surgical system includes a surgical tool associated with a virtual haptic interaction point such that movement of the virtual haptic interaction point corresponds to movement of the surgical tool. The surgical system further includes a processing circuit to establish a virtual entry boundary and activate a haptic object, which constrains the surgical tool after the haptic interaction point crosses the virtual entry boundary. | 06-26-2014 |

20100170361 | Transmission with adjustment member for varying tension force - A transmission apparatus includes a drive member, a driven member, and an at least partially flexible transmission coupled to the drive member and the driven member. The flexible transmission is configured to cause movement of the driven member in response to movement of the drive member. The flexible transmission includes a first tension element having a first portion coupled to the drive member, a second portion coupled to the driven member, and an intermediate portion between the first portion and the second portion. The transmission apparatus also includes an adjustment member that engages the intermediate portion of the first tension element. The adjustment member is configured to be adjusted to vary a tension force applied to the first tension element. | 07-08-2010 |
20110003656 | Transmission with connection mechanism for varying tension force - A transmission includes a drive member, a driven member having a connection mechanism, and an at least partially flexible transmission coupled to the drive member and the connection mechanism of the driven member and configured to cause movement of the driven member in response to movement of the drive member. The connection mechanism is configured to be adjusted to vary a tension force applied to the flexible transmission. | 01-06-2011 |
20110082462 | TOOL, KIT-OF-PARTS FOR MULTI-FUNCTIONAL TOOL, AND ROBOTIC SYSTEM FOR SAME - A tool includes a housing including a receiving portion configured to receive at least a portion of an operating member so as to permit rotation of the operating member relative to the housing while constraining movement of the operating member in a radial direction of the operating member. The tool also includes a coupling device disposed on the housing and configured to couple the operating member to the housing so as to permit rotation of the operating member relative to the housing. The coupling device includes a retaining member configured to engage the operating member to constrain movement of the operating member relative to the housing in a longitudinal direction of the operating member. The retaining member is configured to rotate relative to the housing. | 04-07-2011 |
20110082468 | SURGICAL SYSTEM FOR POSITIONING PROSTHETIC COMPONENT AND/OR FOR CONSTRAINING MOVEMENT OF SURGICAL TOOL - A surgical system for positioning a prosthetic component on an anatomy of a patient includes a surgical tool configured to engage the prosthetic component, a force system configured to provide at least some force to the surgical tool, and a controller programmed to compare a target pose of the prosthetic component and an actual pose of the prosthetic component engaged by the surgical tool and generate control signals that cause the force system to allow movement of the surgical tool within a range of movement and provide haptic feedback to constrain a user's ability to manually move the surgical tool beyond the range of movement. The haptic feedback resists movement of the surgical tool by the user that would cause substantial deviation between at least one aspect of the actual pose of the prosthetic component and a corresponding aspect of the target pose of the prosthetic component. The controller is programmed to generate control signals that cause the force system to maintain the haptic feedback as the user implants the prosthetic component on the anatomy. | 04-07-2011 |
