A swing head mechanism and a medical stapler. The swing head mechanism comprises a rotating component, a swing head pull rod (93), and a housing. At least one first fitting member and at least one second fitting member are respectively provided on the outside of the rotating component and the inside of the housing. When the rotating component rotates relative to the housing until the first fitting member is opposite to the second fitting member, the first fitting member and the second fitting member form an elastic embedding fit. The swing head mechanism facilitates an operator to set different swing angles of a stapler head portion, and can avoid uncontrollable swing of the stapler head portion.

The present disclosure includes apparatuses for a surgical handle assembly. An example apparatus includes a reloadable cartridge assembly and a surgical handle assembly including a spring positioned in the surgical handle assembly at a proximal end of a toothed rack. Proximal movement of the toothed rack causes the spring to be compressed and allows for complete opening of the reloadable cartridge assembly.

A treatment tool includes an end effector, an elongated tubular shaft part, a first deflection part having a proximal end connected to a distal end of the tubular shaft part, a second deflection part having a proximal end connected to a distal end of the first deflection part and having a distal end connected to a proximal end of the end effector, and an operation part configured to operate the end effector, in which, when the first deflection part is deflected with respect to an axis of the tubular shaft part, the second deflection part is deflected to an opposite side with respect to the axis and a distal end of the end effector moves on the axis.

A surgical device comprising a first jaw member, a second jaw member, a clamping member and a clamp apparatus is disclosed. The clamping member is slidably positioned to translate at least partially through the first jaw member. The clamping member engages the first jaw member and the second jaw member, and has a knife blade for cutting tissue. A flange of the clamping member is configured to engage a cam surface to pivot the second jaw member with respect to the first jaw member from an open position toward an approximated position. The clamp apparatus is movable from a retracted position to an advanced position for preventing a gap between proximal portions of the first jaw member and the second jaw member from exceeding a predetermined distance. The clamping member and the clamp apparatus are separately movable.

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.

A surgical apparatus for application of surgical clips to body tissue is provided. The surgical apparatus includes a housing, a drive assembly, a trigger, and a shaft assembly. The trigger is operatively connected with the drive assembly. The drive assembly is at least partially positioned within the housing. The shaft assembly extends distally from the housing and has a first tubular member pivotally connected with a second tubular member located distally from the first tubular member. An articulation mechanism is operatively connected between the first and second tubular members, and includes a gear rack, at least one gear, and a gear segment, respectfully connected with each other to pivot the second tubular member about the pivot axis. The gear rack and at least one gear are located within the first tubular member. The gear segment extends proximally from the second tubular member.

A surgical instrument is disclosed. The surgical instrument can include an end effector, comprising an anvil and a staple cartridge. The surgical instrument can further include a shaft defining a longitudinal axis. The surgical instrument can also include an articulation joint, wherein the end effector is rotatably connected to the shaft about the articulation joint between an unarticulated position and at least one articulated position. The surgical instrument can include means for adjusting the length of a firing stroke as a function of the degree in which the end effector is articulated relative to the longitudinal axis. The surgical instrument can include a sensor configured to defect shifting of lateral portions of a flexible firing bar that extends through the articulation joint. Additionally or alternatively, the surgical instrument can include a relief feature configured to accommodate shifting of lateral portions of a flexible firing bar.

A method of surgical stapling that uses a surgical instrument operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The method includes positioning the end effector at a desired site for surgical stapling. The method also includes controlling one or more of the jaws of the end effector to place the end effector in an open position. The method also includes positioning the end effector such that tissue is located between the jaws. The method also includes clamping the tissue between the jaws by moving at least one of the jaws toward the other jaw. The method also includes advancing a firing beam of the apparatus from a proximal position to a distal position.

A robotic surgical tool is disclosed. The robotic surgical tool can comprise an end effector comprising a firing member; a drive system responsive to a motor-driven input; and a proximal housing comprising a retraction mechanism. The retraction mechanism can comprise a control responsive to a manual input. The control can be rotatable in a first direction through a retraction motion and rotatable in a second direction through a reset motion. The retraction mechanism can further comprise a clutch coupled to the control. The clutch can be configured to drivingly engage the drive system as the control rotates through the retraction motion to supply a proximal retraction stroke to a firing bar and drivingly disengaged from the drive system as the control rotates through the reset motion to prevent any displacement of the firing bar by the retraction mechanism until the control is reset for a subsequent retraction motion.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.
