  • Patent number: 12622722
    Abstract: A medical device includes a blade support, a blade supported by the blade support, and a pin. The blade support includes a bore with an inner portion oriented toward the blade and an outer portion oriented away from the blade. A discontinuity is located at a boundary between the inner and outer portions of the bore. The pin includes a longitudinal axis and a yaw plane is defined perpendicular to the longitudinal axis. A rotational yaw degree of freedom is defined about the longitudinal axis of the pin. The blade support is operable to rotate about the pin in the yaw degree of freedom, contact the pin at the discontinuity of the bore, and tilts away from the yaw plane at the discontinuity of the bore in response to a force applied in a lateral direction.

  • Publication number: 20260021575
    Abstract: An articulable mechanism includes a first link, a second link, and a joint structure coupling the first and second links to each other. The joint structure is configured to enable articulation of the first and second link relative to each other. A first pair of guide channels is defined by and extends through the first link. A second pair of guide channels is defined by and extends through the second link. A lining overlays one or more of at least a portion of the joint structure, the first guide channels, or the second guide channels. A pair of actuation elements extends respectively through the first guide channels, past the joint structure, and through the second guide channels. The lining provides an interior guide surface along at least part of a path of the actuation elements extending through the first and second guide channels and past the joint structure.

  • Publication number: 20250387120
    Abstract: A surgical stapling system can include a reload shaft. The shaft can include an elongate tubular member with have a jaw assembly at the distal end thereof and a coupling collar at the proximal end thereof. The shaft assembly also includes an articulation joint coupling the jaw assembly to the distal end. A drive member and an articulation member extend within the tubular body of the shaft from the proximal end to the distal end. A firing member is connected to the distal end of the drive member such that advancement of the drive beam advances the firing member to close the jaw assemblies and fire staples from a reload positioned in the jaw assembly. The shaft assembly can also include a lockout mechanism to prevent a firing operation on a previously-fired reload or no reload.

  • Publication number: 20250378575
    Abstract: Hand-held controllers continue to be tracked when illuminators on the controllers are occluded. Image data is captured of a hand holding a physical controller with illuminators, and motion sensor data is received from the controller. A determination is made as to whether illuminator-based pose detection is reliable based on the visibility of the illuminators. When the illuminator-based pose detection is not considered reliable, the controller's pose is determined using hand-tracking data for the hand holding the controller. Tracking information for the controller is determined by considering the spatial relationship between the hand and controller in previous frames and adjusting parameters based on a visibility metric. This facilitates generating virtual content that corresponds with the physical controller's current pose.

  • Publication number: 20250359948
    Abstract: A medical device includes a wrist link. a tool member, and a tension element. The wrist link includes a discrete first link piece and a discrete second link piece. The first link piece includes a first clevis ear and the second link piece includes a second clevis car. The second link piece is coupled to the first link piece to position the second clevis ear opposite the first clevis car and to define a tension element guide channel between the first link piece and the second link piece. The tool member is coupled to rotate between the first clevis ear and the second clevis car about a tool member rotation axis. The tension element is coupled to the tool member and extends from the tool member through the tension element guide channel. Tension on the tension element urges the tool member to rotate about the tool member rotation axis.
