SURGICAL CUTTING AND STAPLING INSTRUMENTS WITH INDEPENDENT JAW CONTROL FEATURES Russian patent published in 2019 - IPC A61B17/72

Abstract RU 2684353 C2

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. In various implementations, the surgical instrument includes a surgical end effector that comprises a lower jaw and an upper jaw that are supported for movable travel toward and away from each other. Instrument may further include a firing member that is operably supported for selective operable travel within the surgical end effector. Instrument may also include a first jaw closure system that operably interfaces with the lower jaw and is configured to selectively move the lower jaw relative to the upper jaw. Second jaw closure system operably interfaces with the upper jaw and is configured to selectively move the upper jaw relative to the lower jaw. Firing system operably interfaces with the firing member and is configured to apply firing motions to the firing member to move the firing member within the end effector.

EFFECT: surgical cutting and stapling instruments with independent jaw control features are proposed.
