A surgical anvil assembly for use with a circular stapling instrument includes an anvil center rod defining a longitudinal axis and an anvil head pivotally coupled to the anvil center rod and movable between a first operative condition and a second tilted condition. The anvil assembly further includes a locking assembly configured to selectively lock the anvil head in each of the first and second conditions.

An ingress-egress apparatus for protection of a surgical work site during removal of a surgical implant therefrom includes an inverted frustum surface having a sidewall defining: a bottom open area at a base portion of the frustum surface sidewall, and an opposing top open area at a top portion of the frustum surface sidewall. The top open area has a larger area than the bottom open area. The apparatus includes an ingress port located at the base portion of the frustum surface sidewall and an egress port located at the base portion of the frustum surface sidewall. During surgical removal of the surgical implant using a surgical burr, the apparatus can be used to irrigate the work site, thereby cooling it and protecting it from damage, and further removing metal implant particles generated during burring.

A surgical system includes a robotic arm, an end effector held by the robotic arm, a tracking system configured to detect a patient position and an end effector position, and a processor and non-transitory memory storing instructions that, when executed by the processor, cause the processor to define a planned trajectory relative to the patient position, obtain the patient position and the end effector position from the tracking system during manual movement of the end effector by a user, determine whether the end effector position is within a threshold of the planned trajectory based on the patient position and the end effector position obtained during the manual movement of the end effector, and upon determination that the end effector position is within the threshold of the planned trajectory, take over and control the robotic arm to automatically align the end effector with the planned trajectory.

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.

A system includes a surgical tool, a robot holding the surgical tool, and non-transitory computer-readable memory storing instructions that, when executed, cause the robot to perform operations including automatically moving the surgical tool to a virtual geometry correlated with an anatomical structure and forcing, following arrival of the surgical tool at the virtual geometry, the surgical tool to stay at the virtual geometry while allowing manual repositioning of the surgical tool along the virtual geometry.

A surgical instrument includes a housing, a shaft extending therefrom, an end effector assembly supported by the shaft, a movable handle, and a drive assembly. The drive assembly includes a translatable drive member for actuating the end effector assembly, and a torsion spring including first and second legs. The first leg is configured to translate through the housing in response to movement of the movable handle relative to the housing. The second leg is configured to translate through the housing in cooperation with the first leg to move the drive member longitudinally when a force acting on the drive member is less than a threshold force, and to remain in fixed position, thereby tensioning the torsion spring and retaining the drive member in fixed position when the force acting on the drive member is equal to or exceeds the threshold force.

A surgical device includes an outer member, an inner member, and at least one locking element. The inner member is at least partially supported within the outer member. The at least one locking element is configured in a first arrangement of the surgical device to lock the inner member in a first position and configured in a second arrangement of the surgical device to unlock the inner member from the first position. The at least one locking element is configured to change from the first arrangement to the second arrangement upon coupling the inner member in an operational arrangement to a hand piece.

A surgical stapling device (10) includes a reload assembly (300) having a cartridge assembly (100) and a shipping cap (200) releasably attached to the cartridge assembly (100). The cartridge assembly (100) includes an alignment pin assembly (140) having an alignment pin (144) defining a key hole slot (151) and is movable between a locked position and an unlocked position. The shipping cap (200) includes a locking pin (230) received through the key hole slot (151). When the alignment pin (144) is in the locked position, the alignment pin (144) prevents separation of the shipping cap (200) from the replaceable cartridge assembly (100) and when the alignment pin (144) is in the unlocked position, the alignment pin (144) permits separation of the shipping cap (200) from the replaceable cartridge assembly (100).

An orthopaedic stapler (1) comprising orthopaedic pliers (3) and an orthopaedic staple (2) integrally formed at the distal ends of the pliers (3). The orthopaedic staple (2) comprises a beam portion (4) and two insertion brackets (5) at the two opposite ends (6) of the beam portion (4) and substantially transverse with respect to the beam portion (4). The orthopaedic pliers (3) comprise two lever arms (12) integrally connected to the orthopaedic staple (2) by means of connection portions (15) at the two opposite ends (6) of the beam portion (4). The connection portions (15) are breakable along breakage sections (24). The lever arms (12) comprise at least one first projecting element (19), at least one second projecting element (20), the first projecting element (19) on one lever arm (12) being directed towards the second projecting element (20) on the other lever arm (12). The first projecting element (19) and the second projecting element (20) are provided with a reciprocal engaging mechanism (21).
