Abstract
Various embodiments of tool assemblies are provided having at least one rotary input coupling and at least one linear input coupling for allowing either a rotary output or a linear output (e.g., from a tool driver on a surgical robot) to activate at least one mechanism of the tool assembly. For example, mechanisms of the tool assembly can include a clamping assembly, a firing assembly, an articulation assembly, and a roll assembly. The clamping assembly can open and close jaws of an end effector, the firing assembly can translate a knife assembly through the end effector to fire staples and cut tissue, the articulation assembly can articulate the end effector, and the roll assembly can rotate the elongate shaft and/or the end effector.
Claims6
A surgical tool, comprising:
- a housing;
- an elongate shaft extending distally from the housing and having an end effector with opposed jaws on a distal end thereof;
- a closure tube extending along the elongate shaft for opening and closing the opposed jaws;
- a first clamping assembly positioned between a rotary input and a first part of the closure tube;
- and
- a second clamping assembly positioned between a linear input and a second part of the closure tube,
- wherein the first clamping assembly is configured to translate the closure tube at a first speed for closing the opposed jaws at a first force, and the second clamping assembly is configured to translate the closure tube at a second speed for closing the opposed jaws at a second force, the second speed being greater than the first speed and the first force being greater than the second force.
