Surgical instrument including an articulation lock
A surgical instrument comprising a handle, an elongate shaft, an end effector, an articulation joint, an articulation knob, an articulation member, and an articulation lock is disclosed. The end effector is rotatably coupled to the elongate shaft by the articulation joint. The articulation knob is rotatable between an un-rotated position and rotated positions. The articulation lock comprises a lock member configured to move between a locked position where the lock member is engaged with a detent of the end effector and an unlocked position where the lock member is disengaged from the end effector. The lock member is movable between the locked position and the unlocked position by the articulation knob. The articulation member is moved from a proximal position toward a distal position to articulate the end effector when the articulation knob is moved from the un-rotated position toward a rotated position.
Applicator instruments having stacked surgical fasteners for off-axis surgical fastener delivery
An applicator instrument for dispensing surgical fasteners includes a housing, and an elongated shaft extending from the housing. The elongated shaft has a proximal end secured to the housing, a distal end spaced from the proximal end, and a first axis extending between the proximal and distal ends of the elongated shaft. Surgical fasteners are disposed in the elongated shaft. The surgical fasteners are stacked at an angle relative to the first axis of the elongated shaft. A distal end cap having a surgical fastener dispensing window is secured to the distal end of the elongated shaft. The applicator instrument has a firing system disposed in the housing, and an actuator coupled with the firing system for activating the firing system to dispense the surgical fasteners through the surgical fastener dispensing window.
Methods of using applicator instruments having insertable, changeable cartridges for dispensing surgical fasteners
A method of dispensing surgical fasteners includes providing an applicator instrument having a housing with a cartridge opening, an elongated shaft extending from the housing, a firing system disposed within the housing for dispensing surgical fasteners, and an actuator for activating the firing system. The method includes forming a surgical opening in tissue, inserting a distal end of the elongated shaft into the surgical opening, inserting a cartridge containing a plurality of first surgical fasteners into the cartridge opening, and engaging the actuator for dispensing one of the first surgical fasteners from the distal end of the elongated shaft. While maintaining the distal end of the elongated shaft inside the surgical opening, the cartridge is removed from the cartridge opening, a second cartridge containing a plurality of second surgical fasteners is inserted into the cartridge opening, and the actuator is engaged for dispensing one of the second surgical fasteners from the distal end of the elongated shaft.
METHOD OF COMPRESSING TISSUE WITHIN A STAPLING DEVICE AND SIMULTANEOUSLY DISPLAYING THE LOCATION OF THE TISSUE WITHIN THE JAWS
A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.
Staple cartridge
A staple cartridge can comprise a plurality of staples positioned within a cartridge body, wherein the cartridge body can comprise a tissue-contacting deck and a plurality of ridges extending from the tissue-contacting deck. The ridges can be configured to prevent, or reduce the possibility of, tissue from moving relative to the staple cartridge during use. The staple cartridge can further comprise a plurality of staple cavities, wherein each staple cavity can comprise an opening in the deck which is at least partially surrounded by a ridge. The ridges can comprise a uniform height or a height which varies along the length thereof. The height can vary relative to a proximal end and a distal end of the cartridge body and/or between the center of the cartridge body and the side.
Firing assembly comprising a multiple failed-state fuse
Surgical instruments are disclosed comprising a firing assembly including a fuse having a plurality of operating states.
MEDICAL IMPLANT DELIVERY SYSTEM AND RELATED METHODS
An implant delivery system including a fixation member delivery system including an elongate shaft, first and second rails, a plurality of fixation members with each fixation member slidably disposed on the first and second rails and an actuation assembly. The actuation assembly includes a first elongate member including a first plurality of engagement members disposed along the first elongate member with a distal end region of each engagement member in engagement with one of the fixation members, a second elongate member including a second plurality of engagement members disposed along the second elongate member with a distal end region of each engagement member in engagement with one of the fixation members. Additionally, cyclical actuation of the actuation assembly is configured to incrementally move the fixation members distally along the first and second rails to deploy each of the plurality of fixation members in sequence.
METHODS AND INSTRUMENTS FOR TREATING OBESITY
The invention relates surgical abdominal methods of treating obesity in a patient by implanting a volume filling device that, when implanted in a patient, reduces the food cavity in size by a volume substantially exceeding the volume of the volume filling device. Also disclosed is a laparoscopic instrument for providing a volume filling device to be invaginated in the stomach wall of a human patient to treat obesity.
OBESITY TREATMENT
An apparatus for treating obesity comprises a volume filling device formed by at least two segments and is provided and following implantation, the device is placed resting against the stomach wall of the patient to reduce the inner volume of the stomach, thereby affecting the patients appetite.
APPLICATOR INSTRUMENTS FOR DISPENSING SURGICAL FASTENERS, THE APPLICATOR INSTRUMENTS BEING CONTROLLED BY SURGICAL ROBOTS
A method of dispensing surgical fasteners includes providing an applicator instrument having a housing with a cartridge opening, an elongated shaft extending from the housing, a firing system disposed within the housing for dispensing surgical fasteners, and an actuator for activating the firing system. The method includes forming a surgical opening in tissue, inserting a distal end of the elongated shaft into the surgical opening, inserting a cartridge containing a plurality of first surgical fasteners into the cartridge opening, and engaging the actuator for dispensing one of the first surgical fasteners from the distal end of the elongated shaft. While maintaining the distal end of the elongated shaft inside the surgical opening, the cartridge is removed from the cartridge opening, a second cartridge containing a plurality of second surgical fasteners is inserted into the cartridge opening, and the actuator is engaged for dispensing one of the second surgical fasteners from the distal end of the elongated shaft.
