More Information
Summary: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.
