A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

A treatment tool includes: a sheath; a treatment portion that is capable of treating a living tissue and is provided at a distal end of the sheath; a first driver and a second driver that are inserted in the sheath and are capable of driving the treatment portion; and a holder that is inserted in the sheath, and holds the first driver and the second driver. The holder includes a groove in which the first and second driver are inserted, and an intervening portion provided in the groove and arranged between the first driver and the second driver in a cross section perpendicular to a longitudinal direction of the groove that extends from a distal end to a proximal end of the holder.

A surgical instrument includes a handle assembly and a shaft portion extending distally from the handle assembly and configured to rotate relative to the handle assembly. The handle assembly includes an actuator and a gear that operably couples the actuator to the shaft portion. The gear is configured to transform a rotational motion of the actuator into a rotation of the shaft portion at a greater angular velocity than an angular velocity of the actuator.

Methods and devices for reprocessing a surgical instrument are disclosed. The surgical instrument includes a housing defining a cavity and at least one interior component disposed within the cavity. The housing is opened along a seam to access the cavity, the at least one interior component is serviced, and a mating member is applied to the housing. The housing is joined together with the mating member, and the housing is reopened along the seam to access the cavity.

A medical device includes a handle that includes a handle body longitudinally extending from a proximal end to a distal end; a distal connector configured to connect to a proximal end of an elongate outer member; a lumen longitudinally extending through the handle body, the lumen configured to have an elongate inner member movably disposed therein, and to permit the elongate inner member to distally extend past the distal end to within the elongate outer member and to proximally extend past the proximal end; and an inner member controller configured to longitudinally move relative to the handle body to control movement of the elongate inner member relative to the elongate outer member. The handle may be a distal handle of the medical device, which further includes a proximal handle. Both handles may control movement of the elongate inner and outer members.

A surgical instrument is disclosed comprising an end effector including a first jaw and a second jaw, wherein the first jaw is rotatable relative to the second jaw, and a closure system configured to close the first jaw during a closure stroke. The surgical instrument further comprises an articulation joint rotatably connecting the end effector to the shaft, an articulation system configured to articulate the end effector relative to the shaft, and a firing system operably engaged with the electric motor, wherein the firing member is configured to move through the end effector during a firing stroke. The surgical instrument further comprises a first rotatable member configured to selectively synchronize the motion of the firing system with the motion of the articulation system and a second rotatable member operably engageable with the articulation system, wherein the closure system is configured to stop the rotation of the second rotatable member.

A vibration transmitter includes: a proximal end extending portion; a supported portion; a distal end extending portion; a first relay unit provided between the supported portion and the proximal end extending portion; and a second relay unit provided between the supported portion and the distal end extending portion. The second relay unit includes a horn that is constructed such that an outer diameter at a position continuously adjacent to the supported portion is larger than: (i) an outer diameter of the first relay unit at a position continuously adjacent to the supported portion, and (ii) the outer diameter of the distal end extending portion. The horn expands amplitude of vibration output from a distal end of the distal end extending portion to be larger than a maximum amplitude at an antinode of vibration in the first relay unit or the proximal end extending portion.

Surgical stapling instruments are disclosed comprising a staple cartridge, a firing member, and a cartridge lockout configured to prevent the firing member from being advanced through the staple cartridge if the staple cartridge has been already spent. The stapling instruments further comprise a lockout in the shaft that responds to the cartridge lockout blocking the firing member.

A surgical staple cartridge is disclosed comprising a plurality of staples removably stored within the surgical staple cartridge. The staples comprise staple legs which extend from a staple base portion. The staple legs comprise staple tips configured to pierce tissue and contact a corresponding forming pocket of an anvil of surgical stapling instrument. The staples further comprise zones having different hardnesses.

A method is disclosed. The method can comprise obtaining a first staple cartridge and obtaining a second staple cartridge, wherein the first staple cartridge and the second staple cartridge comprise the same length and the same width. The method can further comprise inserting the first staple cartridge into a channel comprising a keyed profile, wherein complete insertion of the first staple cartridge into the channel is prevented by the keyed profile. Additionally, the method can comprise inserting the second staple cartridge into the channel, wherein complete insertion of the second staple cartridge into the channel is permitted by the keyed profile.
