Abstract:
A staple cartridge is disclosed. The staple cartridge is insertable into and removable from a jaw of surgical stapling instrument. The staple cartridge comprises a cartridge body including staple cavities and staples removably stored in the staple cavities. Each of the staple cavities includes a bottom opening and a top opening. The staples include features configured to inhibit the staples from falling out of the bottom openings of the staple cavities. The staple cartridge further comprises a firing member configured to eject the staples from the staple cavities through the top openings of the staple cavities. The firing member further comprises one or more features configured to inhibit the firing member from falling out of the bottom of the cartridge body. In various instances, as a result, a cover extending around the bottom of the cartridge body may not be required.
Abstract:
Disclosed is a surgical linear stapler comprising: a staple cartridge which is internally loaded with staples for stapling a surgical site; a cartridge accommodating channel which is formed with a cartridge accommodating groove to accommodate the staple cartridge therein; an anvil which corresponds to the staple cartridge and shapes the staple discharged from the staple cartridge; and a cutter which moves along a lengthwise direction of the staple cartridge by external force and cuts a surgical site arranged in between the staple cartridge and the anvil, in which distances from the cutting section of the surgical site to opposite stapling lines are different from each other, thereby stably and conveniently obtaining tissue for pathological examination, which is not damaged by a staple.
Abstract:
A staple housing includes an array of staples each in a staple delivery position or “ready position” ready to be fired into target tissue. A staple driver is advanceable to drive the ready position staples from the staple head into the tissue using staple pushers. During use, the staples in the ready positions are simultaneously fired into the target tissue using the staple pushers, forming an array of staples in the target tissue. After the array has been fired, one or more feed mechanisms within the staple housing advance a second group of staples from one or more staple storage locations into the ready positions in preparation for firing of the second group of staples.
Abstract:
A tissue thickness compensator comprising at least one woven lattice can be positioned in the end effector of a surgical instrument. A fastener cartridge that is positioned in the end effector can comprise at least one cavity configured to receive a fastener. The fastener can be moveable between an initial position, wherein the fastener is at least partially position in a cavity, and a fired position, wherein the fastener is configured to compress a woven lattice of the tissue thickness compensator. The woven lattice can comprise a resilient material such that compression of the woven lattice generates a restoring force. The woven lattice can also comprise an axis that can laterally traverse the fastener cartridge, diagonally traverse the fastener cartridge, or intersect a deck surface of the fastener cartridge. The woven lattice can comprise a hydrophilic substance, which can expand when the woven lattice is severed by a cutting element.
Abstract:
A retainer for assembling tissue thickness compensators to a surgical stapler can comprise a grip, a first surface for supporting a first tissue thickness compensator, a second surface for supporting a second tissue thickness compensator, and clips for aligning and attaching the retainer to the surgical stapler. The clips may align and attach the retainer to a staple cartridge of the surgical instrument. The clips may align the retainer with an anvil of the surgical instrument. An insertion tool may be used in combination with the retainer to insert the retainer into the surgical stapler and to push the tissue thickness compensators against the anvil and/or the staple cartridge of the surgical instrument.
Abstract:
A surgical instrument system can comprise a surgical instrument and an end effector, wherein the end effector can comprise a distal end, a proximal connection portion configured to attach the end effector to the surgical instrument, a first jaw, and a second jaw movable relative to the first jaw, wherein the second jaw is movable between an open orientation, a partially-closed orientation, and a closed orientation. The end effector can further comprise at least one sensor configured to detect the orientation of the second jaw and an array of indicators configured to simulate the orientation of the second jaw.
Abstract:
A tissue thickness compensator can comprise a plurality of fibers. Such fibers can include a plurality of first fibers comprised of a first material and a plurality of second fibers comprised of a second material. A tissue thickness compensator can comprise a plurality of layers wherein each layer can be comprised of one or more medicaments. Certain embodiments are disclosed herein for manufacturing a tissue thickness compensator comprising fibers, for example.
Abstract:
A handle includes a first operation input body provided on a handle main body and configured to rotate in first and second directions to operate a first end effector; an interlock body rotatable relative to the first operation input body; an engaging portion provided in the interlock body and configured to be engaged with the handle main body and to restrict rotation of the first operation input body in the second direction when the first operation input body is rotated in the first direction; and a second operation input body configured to rotate to operate a second end effector, and disengage the engaging portion from the handle main body by pressing the interlock body.
Abstract:
A surgical instrument comprising a handle portion, an elongated portion defining a longitudinal axis and extending distally from the handle portion, and first and second jaw members dimensioned to clamp tissue therebetween. The first jaw member has at least one row of fasteners arranged in a row substantially transverse to the longitudinal axis. A pin is disposed in mechanical cooperation with the first jaw member and is movable between a first position where the engagement section is spaced from the second jaw member and a second position where the engagement section engages the second jaw member. The pin has a non-circular cross-section.
Abstract:
Surgical staplers include: (a) a stapler head having opposed first and second elongate jaws with opposing proximal and distal end portions; (b) a staple cartridge held in at least one of the first and second jaws, the stapler cartridge configured to concurrently deliver a plurality of parallel rows of staples; and (c) a tissue protection segment held in a proximal portion of at least one of the first and second jaws. The jaws are configured to close against target tissue and, at stapler firing, staples are delivered to a subset of tissue held inside the jaws so that tissue held by the tissue protection segment adjacent the proximal end portion of the stapler is not stapled.
