摘要:
A surgical device comprises a housing, a bioprocessing module, an end effector, and a pumping device. The bioprocessing module comprises media reservoirs, fluid conduits in communication with the reservoirs, and a port through which media is expelled. The end effector is configured for insertion into a lumen and delivering a tissue repair composition into that lumen. The end effector has at least one fluid conduit extending therethrough and at least one orifice in communication with the fluid conduit. The fluid conduit in the first end effector is in fluid communication with the port on the bioprocessing module. The pumping device is operable to urge a tissue repair composition comprising at least a portion of the contents of the media reservoirs through the fluid conduit of the first end effector such that the tissue repair composition is expelled from the at least one orifice.

A tissue harvesting and processing apparatus comprises a body and a distally extending needle. The needle includes an aperture configured to receive tissue. A tissue cutting member is movable relative to the needle to sever a specimen from tissue protruding through the aperture. A tissue processor is operable to mince tissue severed by the tissue cutting member. The minced tissue may be mixed with a medical fluid component contained in a reservoir. The medical fluid mixture may be expelled through an applier tip coupled with the body. The tissue processor may comprise a mincing die such that tissue specimens are minced upon being extruded through the mincing die. The tissue processor may comprise a blade that cooperates with a sliding press. The tissue processor may comprise auger blade sections that cooperate with inwardly extending pins. A mixing piston may mix the minced tissue with the medical fluid component.

A surgical tool system. Various embodiments of the surgical tool system may comprise surgical instrument that has a handle assembly that operably supports a drive system therein for generating drive motions upon actuation of a movable handle portion operably coupled to the handle assembly. An elongated body protrudes from the handle assembly and operably supports a control rod therein that interfaces with the drive system. The surgical tool system further includes at least two surgical tools selected from the group of surgical tools consisting of: manipulators, nippers, scissors, endocutters, tissue thickness measurement devices, staple appliers, clip appliers, syringes for applying glue, sealant, drugs or medicaments and cauterization devices wherein each of the surgical tool within the group of surgical tools at least has a housing that is removably couplable to the elongated body and a drive assembly that is removably couplable to the control rod for receiving the drive motions therefrom.

In various embodiments, an anvil of a disposable loading unit including a first member having staple pockets for deforming staples, a first cover plate secured to the first member, and a second cover plate secured to at least one of the first member and the first cover plate, wherein the first and second cover plates can be configured to support the first member. In at least one embodiment, an anvil can include a first member inserted into a second member, where at least one of the first and second members can be deformed to retain one to the other. In various embodiments, a surgical stapling instrument can include a disposable loading unit comprising a staple cartridge, an anvil, and a sleeve, wherein the sleeve can be configured to be slid relative to the staple cartridge and the anvil to hold the anvil in a closed position.

In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

A disposable loading unit for operable attachment to a surgical stapling apparatus. The disposable loading unit may have a carrier that supports a staple cartridge and an anvil assembly that is movable coupled to the carrier. The various embodiments may further have an axial drive assembly that is configured to impart a closing motion to the anvil assembly and also supports a cutting blade thereon. The axial drive assembly is configured to receive firing motions and retraction motions from the surgical stapling apparatus. Various embodiments have an anvil release assembly that enables the anvil assembly to be released from a clamping orientation in the event that the cutting blade becomes jammed during operation.
