Various examples are directed to systems and methods for operating and controlling a modular surgical instrument comprising an operating mode. A controller may receive electrical signal associated with an activation of at least one user-actuated input device electrically coupled to the controller and override the operating mode of the surgical instrument upon receiving the electrical signal.

Various examples are directed to systems and methods for operating a surgical instrument comprising a firing member translatable proximally and distally along a longitudinal axis between a stroke begin position to a stroke end position distal of the stroke begin position; a knife coupled to the firing member; and a motor coupled to the firing member to translate the firing member between the stroke begin position and the stroke end position. A control circuit may receive a firing signal and begin a firing member stroke by providing an initial motor setting to the motor. The control circuit may maintain the initial motor setting for an open-loop portion of the firing member stroke. The control circuit may receive energy data describing energy provided to the motor during the open-loop portion of the firing member stroke and may select a firing control program based at least in part on the energy data.

Aspects of the present disclosure are presented for a surgical instrument having one or more sensors at or a near an end effector and configured to aide in the detection of tissues and other materials and structures at a surgical site. The detections may then be used to aide in the placement of the end effector and to confirm which objects to operate on, or alternatively, to avoid. Examples of sensors include laser sensors used to employ Doppler shift principles to detect movement of objects at the surgical site, such as blood cells; resistance sensors to detect the presence of metal; monochromatic light sources that allow for different levels of absorption from different types of substances present at the surgical site, and near infrared spectrometers with small form factors.

A surgical instrument system comprising a completely replaceable cartridge jaw is disclosed.

Various systems and methods for tracking surgical procedure costs are disclosed. A computer system, such as surgical hub, is configured to be communicably coupled to a plurality of surgical devices. The computer system can be programmed to identify the surgical devices that are being utilized during a surgical procedure via perioperative data received from the surgical devices and then calculate the total cost associated with the surgical devices used in the surgical procedure. The total cost can include an aggregation of the maintenance costs of each of the reusable surgical devices and the replacement costs of the nonreusable surgical devices consumed during the surgical procedure.

A tool for use with a surgical robotic manipulator that comprises an energy applicator including a shaft extending along an axis between a proximal end and a distal end. The shaft has a retention surface and an ejection surface. A tool assembly comprises a support structure to support the energy applicator and an axial connector assembly arranged to engage and releasably lock the energy applicator to the support structure in a locked state via the retention surface. The tool assembly is also configured to apply an ejection force to the energy applicator to provide a tactile indication to the user that the energy applicator is not fully engaged by the axial connector assembly if a suitable force is not provided by the user to overcome the ejection force and place the energy applicator in the locked state.

A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler. The powered handle can include a manual return mechanism.

A method of maintaining a constant movement of a cutting blade of an ultrasonic waveguide includes providing an ultrasonic transducer operable to convert a received motional current into a movement of a cutting blade of an ultrasonic waveguide, a measurement circuit connected in a parallel configuration with the ultrasonic transducer, and a variable power source operable to supply current through a set of connection points to the parallel configuration and thereby create the motional current in the ultrasonic transducer. Current is supplied through a set of connection points of the parallel configuration with the variable power source to, thereby, create the motional current in the ultrasonic transducer and the motional current is regulated with a current controller by varying an output of the power source, thereby maintaining a substantially constant rate of movement of the cutting blade across a variety of cutting loads.

An ultrasonic surgical device comprises a handle assembly, a shaft assembly, and a removable transducer module. The transducer module includes a waveguide, a locking mechanism, and an electronics assembly including at least one button. The handle assembly includes a trigger assembly configured to actuate the button(s) of the electronics assembly when the transducer module is coupled with the handle assembly. The shaft assembly engages the waveguide of the transducer module and is disposed at the distal end of the handle assembly. The distal end of the shaft assembly includes a harmonic blade. When assembled with the handle assembly, the transducer module is capable of providing ultrasonic energy to the harmonic blade.

Some surgical instruments become partially or fully disabled at a device firmware level after being used in a surgical procedure in order to prevent overuse or abuse of the surgical instrument that could create patient safety concerns. A reconditioning device may be used by the end user of such a surgical instrument to perform diagnostics and reconditioning of the surgical instrument so that the surgical instrument may be placed back into service without the direct intervention of the manufacturer. The reconditioning device provides power to the surgical instrument, analyzes device usage history, activates and tests the surgical instrument cutting and gripping functions, and measures electrical characteristics and mechanical characteristics of the surgical instrument. Gathered data is used to determine if the surgical instrument may be safely reconditioned for further use. If reconditioning is possible, the device will be reconfigured for safe use, reactivated, and then sterilized for subsequent re-use.
