Forceps with linear trigger kickout mechanism
A forceps includes shaft members each having a jaw member disposed at a distal end thereof and configured move the jaw members between open and closed position. A knife deployment mechanism includes a trigger moveable along a longitudinal axis to deploy a knife between retracted and extended positions between the jaw members, the knife deployment mechanism including links that cooperate to actuate the knife. A knife kickout mechanism is pivotably coupled to one link and is configured to engage a ramp disposed in a shaft member upon approximation of the shaft members, the knife kickout is configured to cooperate with the links to urge the knife back to an at rest position upon the opening of the shaft members.
DEVICE DELIVERY VIA BILIARY ACCESS DEVICE
A delivery endcap assembly is adapted for use with a biliary access device and is adapted to permit a medical device to be delivered through the biliary access device. The delivery endcap assembly includes a securement portion adapted to be releasably securable to a proximal end of the handle after the one or more removable components have been removed from the handle, a tapered portion extending proximally from the securement portion, a rotation hub adapted to be coupled to the securement portion, a valve adapted to be coupled to the rotation hub and a lumen extending through the delivery endcap assembly, wherein the lumen extending through the delivery endcap assembly is adapted to permit a medical device within an introducer sheath to be advanced through the biliary access device.
Surgical stapling device with firing lockout mechanism
A surgical stapling device includes a tool assembly and a drive assembly for actuating the tool assembly. The tool assembly includes a cartridge assembly having a staple cartridge and an anvil assembly that supports a lockout mechanism. The staple cartridge includes a cartridge body and an actuation sled and knife assembly that includes an actuation sled and a knife. The actuation sled and knife assembly is movable in relation to the cartridge body to eject staples from the cartridge body and to cut tissue. The anvil assembly supports a lockout mechanism that includes a lockout member that is movable between a locked position and an unlocked position. The drive assembly is movable from a retracted position to an advanced position to move the actuation sled and knife assembly from its retracted position to its advanced position. In the locked position, the lockout member obstructs movement of the drive assembly from its retracted position towards its advanced position.
Virtual guidance for ankle surgery procedures
An example method includes registering, via a visualization device, a virtual model of a portion of an anatomy of an ankle of a patient to a corresponding portion of the anatomy of the ankle viewable via the visualization device, the virtual model obtained from a virtual surgical plan for an ankle arthroplasty procedure to attach a prosthetic to the anatomy. The example method also comprises displaying, via the visualization device and overlaid on the portion of the anatomy, a virtual guide that guides at least one of preparation of the anatomy for attachment of the prosthetic or attachment of the prosthetic to the anatomy.
FASTENER CARTRIDGES INCLUDING EXTENSIONS HAVING DIFFERENT CONFIGURATIONS
A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The cartridge body can further comprise extensions extending from the deck having different sizes and/or configurations. The extensions can control the flow of tissue relative to the deck and/or support the fasteners as they are ejected from the fastener cavities.
SAFETY SHIELDS FOR ELONGATED INSTRUMENTS AND RELATED SYSTEMS AND METHODS
A system can include an elongated instrument that is positioned within a cannula portion of a cannula assembly. The system can include a shield that is coupled with both the elongated instrument and the cannula assembly when in an unlocked state. The shield can permit proximal movement of the elongated instrument relative thereto when in the unlocked state. The shield can automatically transition to a locked state to attach to a distal end of the elongated instrument to restrict access to a distal tip of the elongated instrument.
End effector of a surgical robotic manipulator including a grip sensing mechanism for manual operation of the end effector
An end effector is disclosed for use with a surgical robotic manipulator and a cutting accessory. The end effector comprises a nose tube for receiving the cutting accessory and an actuator for driving the cutting accessory. The end effector may also comprise a mounting fixture for coupling the end effector to the surgical robotic manipulator and a handle for gripping by the user. The handle may be coupled to the nose tube and configured to rotate about the axis of the nose tube. The end effector may also comprise a lever coupled to the handle and moveable between depressed and released positions. The end effector may further comprise an activator coupled to the lever and configured to interact with a sensor for sensing the position of the lever.
CUTTING INSTRUMENT WITH SAFETY SLEEVE
A surgical cutting instrument comprises a handle portion and an elongate shaft. The shaft has a distal end and a proximal end and a longitudinal axis extending therebetween, and a cutting element is mounted at the distal end. The instrument further comprises a safety sleeve which includes a substantially cylindrical channel through which the elongate shaft extends. The safety sleeve is moveable axially along the shaft between the proximal end and the distal end of the shaft. The instrument further comprises locking means for preventing further axial movement of the safety sleeve with respect to the elongate shaft when the safety sleeve is in the extended position. The locking means comprises first and second cooperating elements each located on a respective one of the distal end of the shaft and the safety sleeve. A method for using the cutting instrument is also provided.
Surgical stapling device with knife blade lock
A surgical stapling device includes a cartridge assembly including a cartridge body, a staple pusher, a knife assembly, and a locking device. The locking device is configured to prevent readvancement of the knife assembly.
SURGICAL STAPLING INSTRUMENTS COMPRISING SHORTENED STAPLE CARTRIDGE NOSES
A surgical stapling instrument is disclosed. An end effector for the surgical stapling instrument comprises a staple cartridge assembly and an anvil. The staple cartridge assembly comprises a proximal end, a distal end, and a cartridge body comprising a shortened nose at the distal end. The staple cartridge assembly further comprises staples removably stored in the cartridge body, a driver configured to support at least one of the staples, and a sled movable toward the distal end. The sled comprises a ramp configured to lift the driver and at least one of the staples and a base, wherein the shortened nose of the cartridge body is shorter than the base of the sled. The anvil comprises a staple forming surface comprising a plurality of staple forming pockets and a blunt distal nose extending downward toward the staple cartridge assembly.
