A surgical stapling device includes a cartridge assembly including a staple pusher, a knife holder, a knife supported on the knife holder, and a biasing member. The biasing member is positioned between the staple pusher and the knife holder to prevent re-advancement of the knife blade after the stapling device is fired.

A surgical stapling device includes a removable or releasable cartridge assembly. The surgical stapling device and the cartridge assembly include engagement members for releasably securing a thrust bar of the stapling device to a knife assembly of the cartridge assembly. The stapling device also includes structure to prevent the knife assembly from being disengaged from a cartridge body of the cartridge assembly and for obstructing advancement of the knife assembly within the cartridge body after the stapling device has been fired.

A surgical stapling device includes a reload assembly that includes a locking member to retain a knife carrier of the reload assembly in a retracted position after the stapling device is fired. The locking member may be supported on an inner housing portion of the shell housing or on a staple pusher assembly of the reload assembly.

Anchor delivery systems include markings on the surfaces of the delivery device which are visually exposed to the user through openings or fenestrations in the anchor, providing visual feedback to the user on the progress of the anchor's insertion. A suture-locking plug is deformable within the anchor tip, thereby enhancing suture entrapment within the tip of the anchor. A compliant component of the handle places the handle components in tension, thereby absorbing built-in axial looseness in the handle. The handle further includes a spin cavity which allows for free spin of the inserter shaft to finalize insertion of the anchor into bone when the anchor has not been fully seated flush with or below the cortical bone surface.

A tip protector, for a surgical instrument having a shaft and an instrument tip near a distal portion of the shaft, includes a tip housing for releasably receiving the instrument tip; a clamp system suitable for gripping a portion of the surgical instrument to position the tip protector; and a distal through opening at or near the distal end of the tip housing. The distal through opening has an opening size that is adjustable.

A method for operating a surgical instrument is disclosed.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

Surgical instruments and their methods of use are disclosed. In some embodiments, the surgical instrument may include a handle and an elongated shaft extending distally from the handle. The surgical instrument may also include a fastener deployment system for deploying fasteners from the elongated shaft including a reciprocating driveshaft disposed within the elongated shaft. In other embodiments, the fastener deployment system may include a follower disposed within the elongated shaft for displacing one or more fasteners within the elongated shaft towards a distal fastener deployment position. In some embodiments, the surgical instrument may include a removable preload lock-out attached to the elongated shaft to prevent the follower from applying a preload to the fasteners.

An end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly and a biasing element. The driver is disposed in mechanical cooperation with the drive assembly. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The biasing element is disposed in mechanical cooperation with the needle assembly and is configured to bias the needle assembly proximally.

The invention relates to a safety cartridge (1) for a removable vena cava filter (20), having a proximal end (2) and a distal end (3) and having an inner channel (4) extending between the ends. The cartridge is characterized in that it comprises, on the distal end (3) thereof, a linking device (5) for forming a link with a catheter (30) and, in the inner channel thereof, a projection (6) having a limited size in the axial direction of the cartridge (1) so as to locally reduce the cross-section of the channel (4).
