20210052332 | Articulable Wrist with Flexible Member and Pivot Guides - An articulable wrist for an end effector includes a first linkage, a second linkage rotatably coupled to the first linkage at a first articulation joint, and a flexible member extending at least partially through a central channel cooperatively defined by the first and second linkages. A first pivot guide is rotatably coupled to the second linkage at the first articulation joint and rotatable about a first pivot axis extending through the first articulation joint, the first pivot guide defining a central aperture alignable with the central channel and sized to accommodate the flexible member therethrough. The first pivot guide supports an outer diameter of the flexible member at the first articulation joint and prevents the flexible member from flexing beyond the first pivot axis during articulation. | 2021-02-25 |
20210052333 | Articulable Wrist with Flexible Member and Roller Supports - An articulable wrist for an end effector includes a first linkage rotatably coupled to a second linkage at a first articulation joint, a flexible member extending at least partially through a central channel cooperatively defined by the first and second linkages, and a first pair of roller supports arranged at the first articulation joint and laterally offset from each other, each roller support extending parallel to a first pivot axis extending through the first articulation joint. A drive cable extends through a first axially-extending conduit defined in the flexible member and through a gap defined between the first pair of roller supports. The drive cable is supported at the first articulation joint by the first pair of roller supports during articulation and the first pair of roller supports prevents a centerline of the drive cable from moving past the first pivot axis during actuation of the end effector. | 2021-02-25 |
20210052334 | Consistent and Repeatable Jaw Gap for Surgical Tool End Effector - An end effector for a surgical tool includes a first jaw that defines an aperture, a second jaw rotatably coupled to the first jaw, and a spacer pin received within the aperture and protruding from an upper surface of the first jaw. The spacer pin is adjustable within the aperture to define a jaw gap between the first and second jaws when the second jaw is moved to a closed position and engages the spacer pin, and the spacer pin is secured within the aperture to set the jaw gap. | 2021-02-25 |
