  • Patent number: 11344375
    Abstract: Surgical assemblies, instruments, and related methods are disclosed that control tissue gripping force. A method for controlling grip force in a robotic surgical instrument includes actuating an input link of a spring assembly. An actuation force is transferred from the input link to an output link of the spring assembly. Relative movement is inhibited between the input link and the output link when the transferred actuation force is below a predetermined level with a preloaded spring of the spring assembly. The input link is moved relative to the output link by deforming the preloaded spring when the transferred actuation force increases above the predetermined level. A grip mechanism is actuated via the output link.

  • 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.
