Abstract

A surgical instrument and method of operating on a tissue includes a shaft assembly and an end effector. The end effector extends in a longitudinal direction from the shaft assembly and has a first jaw, a second jaw, and a deformable hydraulic member. The second jaw is movably mounted relative to the first jaw and is configured to transition between an open configuration and a closed configuration. The first and second jaws are thus configured to have the tissue positioned therebetween in the closed configuration. The deformable hydraulic is configured to contain a fluid. With the fluid contained in the deformable hydraulic member, the deformable hydraulic member is configured to sever the tissue positioned between the first and second jaws in the closed configuration.

Claims20

Dependent claims

A surgical instrument, comprising:

(a) a shaft assembly;
and
(b) an end effector extending in a longitudinal direction from the shaft assembly, the end effector comprising:
(i) a first jaw,
(ii) a second jaw movably mounted relative to the first jaw and configured to transition in a transverse direction from an open configuration toward a closed configuration such that the first and second jaws are configured to have tissue positioned transversely therebetween in the closed configuration, and
(iii) a first deformable hydraulic member extending longitudinally and configured to expand to an expanded state, wherein at least a portion of the first deformable hydraulic member transversely aligns with at least one of the first and second jaws to extend transversely over the at least one of the first and second jaws in the expanded state, wherein the first deformable hydraulic member is configured to contain a fluid,
wherein the first deformable hydraulic member with the fluid contained therein is configured to fracture the tissue positioned between the first and second jaws in the closed configuration.
