CUTTING MECHANISMS FOR SURGICAL END EFFECTOR ASSEMBLIES, INSTRUMENTS, AND SYSTEMS

A surgical system includes an attaching device having an end effector disposed at the distal end thereof. The end effector includes a support member, a wrist pivot pivotably coupling the end effector to the attaching device, and first and second jaw members pivotably coupled to one another and the support member. A first cable is operably coupled to the wrist pivot and configured to articulate the end effector relative to the attaching device. Second and third cables are operably coupled to the jaw members and configured to pivot the jaw members relative to the support member. A first actuation of the second and third cables collectively pivots the first and second jaw members relative to the support member. A second actuation of the second and third cables pivots the first and second jaw members relative to one another and the support member between a spaced-apart position and an approximated position.

A device sized and shaped for insertion into a body comprising: at least one mechanical limb comprising: a support segment; a first flexible section extending from the support segment and terminating in a coupling section; and a second flexible section extending from the coupling section and terminating in a tool or a connector for a tool; wherein a long axis of one or more of the flexible sections is bendable in a single bending plane; wherein a long axis length of the first flexible section is at least double a maximum extent of the first flexible section perpendicular to a flexible section long axis; wherein a long axis length of the second flexible section is at least double a maximum extent of the second flexible section perpendicular to a flexible section long axis.

Multi-shield spinal access system

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

Single piece bending neck for an articulating ultrasound probe

A bending neck comprising a plurality of pivotally connected hollow links is formed by machining a tube to form individual, pivotally connected links. A second tube may be located inside the first tube and simultaneously machined with the first tube. Grooves are formed on opposite sides of the outer surface of the second tube to provide a passageway for control cables which control the articulation of the links. In a second implementation indentations are formed in the side of the single tube to form ring-like projections into the inner lumen of each link, through which the control cables may pass.

Steerable medical device and method

An apparatus, method, and system for a steerable medical device, configured to be used in conjunction with guide tools and devices in medical procedures, including endoscopes, cameras, cutting tools and catheters.

ARTICULATION FEATURES FOR ULTRASONIC SURGICAL INSTRUMENT

A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer. The articulation section includes a collar that is located distal to a nodal portion of the waveguide and is operable to deflect the end effector away from the longitudinal axis. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The articulation drive assembly is operable to drive articulation of the articulation section. The articulation drive assembly comprises at least one translating articulation driver coupled with the collar. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue even when the articulation section is in an articulated state.

ULTRASONIC SURGICAL INSTRUMENT WITH MOVABLE RIGIDIZING MEMBER

A surgical apparatus includes a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and a rigidizing member. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide includes a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section includes a first member and a second member. The second member is longitudinally translatable relative to the first member. The end effector includes an ultrasonic blade in acoustic communication with the waveguide. The rigidizing member is configured to selectively engage at least a portion of the articulation section to thereby selectively provide rigidity to the articulation section.

ULTRASONIC TRANSDUCER ALIGNMENT OF AN ARTICULATING ULTRASONIC SURGICAL INSTRUMENT
20230225752 · 2023-07-20 ·

An ultrasonic surgical instrument and method of deflecting an end effector includes the end effector having an ultrasonic blade, a shaft assembly defining a longitudinal axis, and a body assembly. The shaft assembly has an articulation section configured to articulate from a straight configuration to an articulated configuration and an acoustic waveguide with a flexible waveguide portion positioned within the articulation section. The body assembly proximally extends from the shaft assembly and includes a housing and a shiftable transducer. The shiftable transducer is secured to the acoustic waveguide and configured to generate an ultrasonic energy. In addition, the shiftable transducer assembly is movably mounted relative to the housing and configured to accommodate deflection of the end effector.

STAPLE CARTRIDGE AND DRIVE MEMBER FOR SURGICAL INSTRUMENT
20230225731 · 2023-07-20 · ·

The present disclosure provides a surgical instrument, such as a tissue sealing instrument, having a staple cartridge with a staple pusher and a staple; and a drive member configured to translate distally through the instrument. The drive member includes a lateral projection configured to engage the staple pusher and drive the staple into tissue. The lateral projection of the drive member has a height substantially less than the height of the staple cartridge, thereby requiring less clearance as it translates through the staple cartridge. In addition, the lateral projection has a smaller footprint than conventional drive members resulting in a more compact distal tip on the staple cartridge, which allows for a more compact and maneuverable surgical instrument.
