  • Publication number: 20230200803
    Abstract: An end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly and a biasing element. The driver is disposed in mechanical cooperation with the drive assembly. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The biasing element is disposed in mechanical cooperation with the needle assembly and is configured to bias the needle assembly proximally.

  • Patent number: 11298123
    Abstract: According to an aspect of the present disclosure, an end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly, and a follower. The drive assembly includes a first helical groove. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The follower is configured to engage the first helical groove of the drive assembly. When the follower is engaged with the first helical groove, rotation of the drive assembly in the first direction causes distal translation of the follower with respect to the drive assembly.

  • Patent number: 11191673
    Abstract: A surgical portal apparatus includes a sleeve having a proximal end and a distal end that extends along a longitudinal axis, and a surgical tape. The sleeve includes an inner wall defining an internal longitudinal passageway dimensioned for permitting passage of a surgical object therethrough and an outer wall configured for positioning against tissue. The inner and outer walls define at least a partial annular space therebetween, the annular space being in fluid communication with an opening in the outer wall. The surgical tape includes a body portion retained within the annular space of the sleeve and a leading tab extendable through the opening in the outer wall of the sleeve. The surgical tape has a first surface and a second surface, each of the first and second surfaces having at least one of tissue reactive functional groups and self-reactive functional groups.
