End effectors, surgical stapling devices, and methods of using same

An end effector for use to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket defined by the anvil face, where the first staple pocket comprises a first cup and a second cup for staple formation. The cartridge has a first staple and a first driver. The first staple, once deployed by the first driver and deformed by the first staple pocket, has a formed configuration in which a first portion of a first staple leg and a second portion of a second staple leg are bent relative to a crown and cross the midpoint of the crown and one of the first portion and the second portion overlaps the other of the first portion and the second portion.

A surgical end effector assembly is disclosed. The surgical end effector assembly comprises a shaft, an end effector comprising a first jaw and a second jaw movable relative to the first jaw, and an articulation joint attaching the end effector to the shaft, wherein the articulation joint defines an articulation axis about which said end effector is articulatable relative to the shaft. The articulation joint comprises a first rotary drive member rotatable about the articulation axis and a second rotary drive member rotatable about the articulation axis, wherein the first rotary drive member and the second rotary drive member are rotatable in the same direction to articulate the end effector about the articulation axis. The surgical end effector assembly further comprises a jaw drive output cooperatively driven by the first rotary drive member and the second rotary drive member configured to clamp and unclamp tissue with the second jaw.

A medical clip, in particular in the form of an aneurysm clip, includes two clamping arms and a biasing element. A clamping arm is arranged or formed on a free end of the biasing element. The two clamping arms abut against one another in a basic position and are movable away from one another against the action of the biasing element into an open position. At least part of a surface of the clip is of colored configuration. The clip defines at least three clip regions that are spatially separate from one another. Adjacent clip regions of the at least three clip regions are of differently colored configuration.

SURGICAL DEVICE

A surgical device includes a forceps device, driven portions to which a driving force is transmitted from outside the surgical device, plural wires, each being fixed to one of the driven portions and transmitting respective movements of the driven portions to the forceps device. The forceps device includes grasping portions that may be opened and closed by a movement of a first wire of the plural wires, and a joint portion that may be bent by a movement of one or more second wires of the plural wires.

ROTATIONAL ACTUATORS FOR SURGICAL ROBOTICS SYSTEMS
20230145215 · 2023-05-11 ·

A system for use in surgery includes a central body, a visualization system operably connected to the central body, a video rendering system, a head-mounted display for displaying images from the video rendering system, a sensor system, and a robotic device operably connected to the central body. The visualization system includes at least one camera and a pan system and/or a tilt system. The sensor system tracks the position and/or orientation in space of the head-mounted display relative to a reference point. The pan system and/or the tilt system are configured to adjust the field of view of the camera in response to information from the sensor system about changes in at least one of position and orientation in space of the head-mounted display relative to the reference point.

END EFFECTORS, SURGICAL STAPLING DEVICES, AND METHODS OF USING SAME

An end effector for use to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket defined by the anvil face, where the first staple pocket comprises a first cup and a second cup for staple formation. The cartridge has a first staple and a first driver. The first staple, once deployed by the first driver and deformed by the first staple pocket, has a formed configuration in which a first portion of a first staple leg and a second portion of a second staple leg are bent relative to a crown and cross the midpoint of the crown and one of the first portion and the second portion overlaps the other of the first portion and the second portion.

A SURGICAL INSTRUMENT

A handheld electrosurgical instrument with jaws at a distal end of a shaft. For moving the jaws, the instrument includes a linkage structure with at least three pivots which are movable relative to the housing and with at least pivot which is fixed to the housing. By this arrangement, one of the movable pivots may move as a substitute for movement of the jaws, and the instrument may therefore always have the same limits for handle movement e.g. also if the jaws are prevented from moving. Additionally, a more uniform closure pressure may be ensured independently on the force applied to the handle.

Surgical instruments for grasping and treating tissue

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.
