In one general aspect, various embodiments of the present invention can include a motorized surgical cutting and fastening instrument having a drive shaft, a motor selectively engageable with the drive shaft, and a manual return mechanism configured to operably disengage the motor from the drive shaft and retract the drive shaft. In at least one embodiment, a surgeon, or other operator of the surgical instrument, can utilize the manual return mechanism to retract the drive shaft after it has been advanced, especially when the motor, or a power source supplying the motor, has failed or is otherwise unable to provide a force sufficient to retract the drive shaft.

Powered surgical cutting and stapling apparatus with manually retractable firing system

A motor-driven surgical instrument that may comprise (i) a moveable drive member that is driven in a first direction when the electric motor operates in a first direction and that is driven in a second direction when the electric motor operates in a second direction. Movement of the drive member causes movement of the moveable component of the end effector, and (ii) a motor control circuit connected to the motor for controlling the motor. The motor control circuit may comprise a switching circuit that, upon actuation, reverses the direction of the motor from the first direction to the second direction. The switching circuit may be actuatable separately through each of: (i) actuation of a moveable actuator of the switching circuit through movement of the drive member at least in the first direction; and (ii) manual actuation by a user of the surgical instrument.

Motor-driven surgical cutting instrument with electric actuator directional control assembly

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.

End effector coupling arrangements for a surgical cutting and stapling instrument

A motor-driven surgical cutting and fastening instrument that comprises an end effector, an electric motor, and a motor control circuit. The motor control circuit is for monitoring a parameter of the electric motor that is indicative of movement of a moveable member of the end effector, and for adjustably controlling the electric motor based on the monitored parameter to thereby adjustably control movement of the moveable member of the end effector during forward rotation of the electric motor.

Motor-driven surgical cutting instrument

Surgical methods involving cutting and sealing tissue include affixing a first adjunct material to tissue at a treatment site, such as by stapling the adjunct to tissue. A second adjunct material is applied to at least a portion of the first adjunct material such that the second adjunct material interacts with the first adjunct material to form a seal in an area of the tissue covered by at least one of the first and the second adjunct material. The resulting tissue sealing structure, which includes a combination of the two adjuncts, is believed to be superior to the sealing properties of either adjunct alone.

Adjunct materials and methods of using same in surgical methods for tissue sealing

Various embodiments are directed to battery packs for use with surgical instruments. The battery packs may comprise a plurality of cells and at least a portion of the plurality of cells may not be electrically connected to one another. The battery packs may comprise a switch or other mechanism for interconnecting the plurality of cells and may also comprise, or be used in conjunction with, a discharge switch or plug configured to electrically connect an anode of the battery pack to a cathode of the battery pack, for example, via a resistive element.

Surgical instrument battery comprising a plurality of cells

A tissue thickness compensator may generally comprise a compressible core comprising a plurality of movable particles, and a wrap surrounding the compressible core. The plurality of movable particles may comprise at least one medicament. A tissue thickness compensator may generally comprise a compressible core comprising a plurality of crushable particles, and a wrap surrounding the compressible core. The plurality of crushable particles may comprise at least one medicament. The compressible core may comprise a material selected from a group consisting of a biocompatible material. The wrap may comprise a material selected from a group consisting of a biocompatible material. Articles of manufacture comprising the tissue thickness compensator and methods of making and using the tissue thickness compensator are also described.
