摘要:
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.

A surgical instrument includes an end effector with a staple cartridge. The end effector and staple cartridge extend along a centerline and have an arcuate portion. The staple cartridge includes a deck and a plurality of staples. The plurality of staples include an outer set of staples and an inner set of staples for respective receipt within outer and inner rows of staple openings formed through the deck. At least one staple of the outer set of staples has an elongated crown relative to the inner set of staples such that the outer set of staples are configured to overlap with the inner set of staples in a direction transverse to the centerline.

A surgical instrument includes a shaft assembly, an end effector, and a staple cartridge. The end effector includes a first jaw and a second jaw. The first jaw includes an anvil that is configured to form a plurality of staples pressed against the anvil. The first and second jaws are configured to transition between an open configuration and a closed configuration. The staple cartridge is received within the second jaw. The staple cartridge includes a deck and a plurality of staples. The deck has a plurality of staple openings. The staples are positioned within respective staple openings. At least one of the staple openings obliquely crosses a centerline of the end effector.

The present invention includes a surgical stapler having a staple cartridge, an anvil, and a cutting member having a cutting surface, wherein the cutting member is relatively movable with respect to the anvil and the staple cartridge. In at least one embodiment, the anvil is movable between an open position and a partially-closed position. When the anvil is in its partially-closed position, the anvil and the staple cartridge can be configured to capture tissue therebetween without fully compressing the tissue. In at least one embodiment, the anvil includes a proximal portion, a distal portion, and a middle portion intermediate the proximal portion and the distal portion. In these embodiments, the tissue can be captured between the proximal and distal portions of the anvil before the middle portion of the anvil is brought into contact with the tissue.

An implantable adjunct for use with a surgical stapling instrument is provided. The implantable adjunct comprises means for allowing a clinician to determine the degree of skew, if any, that the adjunct may experience when implanted into a subject with a surgical stapling instrument. The implantable adjunct comprises one or more reference systems configured to be compared to the staples, the edges of the adjunct, and/or any other adjunct elements by a clinician once the adjunct has been implanted into the subject. The one or more reference systems comprise references that define one or more zones of the adjunct. A clinician can visually determine what zone, or zones, of the adjunct the staples have satisfactorily, and/or unsatisfactorily, purchased the adjunct.
摘要:
A surgical stapling instrument that is configured to be used in connection with different sizes of interchangeable end effectors. The end effectors are removably couplable to an elongated shaft assembly that protrudes from a handle assembly. The end effectors are configured to support different sizes of implantable staple cartridges therein. The staples within the staple cartridge are formed as an anvil portion of the end effector is compressed into the staple cartridge. The surgical stapling instrument further includes removable adapters that facilitate attachment of different sizes of end effectors to the elongated shaft assembly.

A surgical staple driver array. The array comprises a distal staple driver configured to operably support at least two distal surgical staples thereon that are each oriented in a distal direction. At least one first intermediate staple driver is configured to operably support at least two first surgical staples oriented in a first direction and at least two second surgical staples oriented in a second direction that differs from the first direction. At least one second intermediate staple driver is configured to be slidably supported adjacent at least one of the distal staple driver and a corresponding one of the first intermediate staple drivers. Each of the second intermediate staple drivers is configured to operably support five surgical staples thereon.
摘要:
A surgical staple driver configured for use with a surgical staple cartridge that operably interfaces with a surgical instrument camming member that is axially movable along a first cam axis. A driver body is slidably supportable within the surgical staple cartridge. A camming surface is provided on the driver body that is oriented for camming engagement with the camming member along the first cam axis. The driver further includes a staple supporting portion that is configured to operably support at least one surgical staple thereon relative to the camming surface such that when the camming member engages the camming surface, the camming member passes transversely under a portion of a staple crown of at least one surgical staple supported on the staple supporting portion.

A surgical instrument system can comprise, one, a surgical instrument (9000) including a handle, a shaft (9040) comprising a distal end, and a trigger (9014) and, two, an end effector (9060) attachable to the shaft. The instrument can further include a firing member and a motor (100) configured to move the firing member (9020) toward the distal end, wherein the trigger is configured to operate the motor. The surgical instrument system can further include a plurality of sensors configured to detect one or more error conditions, a plurality of indicators, and a controller in communication with the plurality of sensors and the indicators, wherein the controller is configured to selectively activate the indicators to indicate the error conditions detected. A surgical instrument can comprise a plurality of actuators and a plurality of actuator locks, wherein the controller can actuate one or more of the actuator locks to indicate the error condition detected.
摘要:
A staple cartridge is disclosed. The staple cartridge comprises a cartridge body including staple cavities and staples removably stored in the staple cavities. The staple cartridge further comprises a firing member configured to eject the staples from the staple cavities. The staples and staple cavities include features which reduce friction forces between the staples and the staple cavities when the firing member ejects the staples from the staple cavities. Each of the staples comprises a base including a drive portion and staple legs extending from the base and, in at least one instance, each of the staple cavities includes a proximal guide and a distal guide configured to guide the staple legs of the staple positioned therein as it is ejected from the staple cavity. In certain instances, each of the staple cavities further includes an intermediate guide offset from the proximal guide and the distal guide.
