A safe surgical instrument that allows a surgeon to move a head section by simple manual operation, and having a reduced number of components, comprises a distal tool head and first and second proximal operation sections. The tool head comprises a movable section and a base section. A first connection structure includes a first conversion mechanism, a first shaft, a universal joint provided at the distal and of the first shaft, a second conversion mechanism, and a crank at the distal end of the second conversion mechanism and connected with the proximal end of the movable section. A second connection structure includes a cylindrical shaft having a pinion at its distal section, and an approximately semicircular rack that meshes with the pinion. The intersection of the axes of the pivots of the universal joint is on the axis of rotation of the rack.

A surgical instrument system comprising a handle, a shaft, and a disposable power module is disclosed. The handle comprises a motor, a control switch, and a motor-control processor which is in communication with the control switch. In various instances, the disposable power module comprises a disposable battery and a display unit configured to indicate at least one function of the surgical instrument system.

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

A method for adjusting the operation of a surgical suturing instrument using machine learning in a surgical suite is disclosed. The method comprises gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical suturing instrument comprising a suturing needle configured to be mechanically advanced through a suturing stroke, analyzing the gathered data to determine an appropriate operational adjustment of the surgical suturing instrument, and adjusting the operation of the surgical suturing instrument to improve the operation of the surgical suturing instrument.

A surgical tool configured for operation in connection with a robotic system. The surgical tool includes a shaft and an end effector extending distally from the shaft. The end effector comprises a first jaw member and a second jaw member movable relative to the first jaw member from a closed position to an open position in response to at least one axial motion. In addition, the surgical tool includes a motor configured to generate at least one rotational motion and a motion conversion assembly operably coupled to the motor and the second jaw member, wherein the motion conversion assembly is configured to convert the at least one rotational motion to the at least one axial motion.

A surgical instrument. The surgical instrument has a force delivery system which communicates a changing force to a user of the surgical instrument when a limit of a surgical function is reached. A sensor senses position of a moving element to communicate a signal to the force delivery system. In various embodiments, the system generates a vibratory force to signal the user.

A surgical instrument including an end effector that has a selectively reciprocatable implement movably supported therein. The implement is selectively advanceable in a distal direction upon application of a rotary actuation motion thereto and retractable in a proximal direction upon application of a rotary retraction motion thereto. An elongate shaft assembly is coupled to the end effector and is configured to transmit the rotary actuation motion and rotary retraction motion to the reciprocatable implement from a robotic system that is configured to generate the rotary actuation motion and said rotary retraction motion.

A surgical clip applier is provided and includes a ratchet mechanism having a rack member connected to a drive channel such that axial translation of the drive channel results in axial translation of the rack member, the rack member defining a first set of teeth along a first side thereof and a second set of teeth along a second side thereof. The ratchet mechanism including a first pawl and a second pawl each tiltably supported in the housing and disposed on respective opposed sides of the rack member; and a buckling spring interposed between the first pawl and the second pawl and constrained in a slot formed in the rack member, wherein the buckling spring is dimensioned so as to bow in one of a proximal direction and a distal direction.

A medical instrument has a shaft with a longitudinal axis, a jaw head on a distal end of the shaft having two jaw parts, at least one of the jaw parts being pivotable about a pivot axis extending transversely to the longitudinal axis, the pivotable jaw part having a wheel portion with toothing mounted about the pivot axis, at least one actuation element having a distal end portion with toothing that meshes with the toothing of the wheel portion such that movement of the actuation element along the longitudinal axis pivots the pivotable jaw part, control elements at a proximal end of the shaft controlling movement of the actuation element, said distal end portion with toothing is flexible, one of the jaws having a hollow space arranged distally to the pivot axis, wherein the distal end portion comes in or out of the hollow space when moving the actuation element.

A method for deforming a staple comprising a base, a first staple leg, and a second staple leg, wherein the base, the first staple leg, and the second staple leg are positioned within a common plane prior to being deformed, the method comprising positioning the first staple leg within a first cup of a staple pocket, the first cup comprising a first inner surface, applying a first compressive force to the first staple leg to bend the first staple leg toward the base and the second staple leg, contacting the first inner surface with the end of the first staple leg to bend the end of the first staple leg toward a first side of the base, and deforming the first staple leg such that the end of the first staple leg crosses a mid-line of the staple defined between the first staple leg and the second staple leg.
