Abstract: A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, and a timer circuit coupled to the control circuit. The timer circuit is configured to measure elapsed time and to to receive, from the position sensor, a position of the displacement member in a current zone during a set time interval, measure displacement of the displacement member at a set time at the end of the set time interval, wherein the measured displacement is defined as the distance traveled by the displacement member during the set time interval at a set command velocity for the current zone, and set a command velocity of the displacement member for a subsequent zone based on the measured displacement of the displacement member within the current zone.

Abstract: A method for authenticating the compatibility of a staple cartridge with a surgical instrument is disclosed. The method can comprise inserting a staple cartridge into a surgical instrument, receiving a first signal from a first RFID tag on a first component of the staple cartridge with an RFID reader system, receiving a second signal from a second RFID tag on a second component of the staple cartridge with the RFID reader system, comparing the first signal and the second signal to stored data for a compatible staple cartridge, and locking a staple firing system of the surgical instrument if the first signal and the second signal do not match the stored data for a compatible staple cartridge.

The surgical instrument includes a displacement member, a motor coupled to the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, and a timer circuit coupled to the control circuit. The control circuit is configured to receive, from the position sensor, a position of the displacement member in a current zone defined by a set displacement interval, measure time at a set position of the displacement interval, wherein the measured time is defined as the time taken by the displacement member to traverse the displacement interval, and set a command velocity of the displacement member for a subsequent zone based on the measured time in the current predefined zone.

Abstract: A surgical hub may have cooperative interactions with one of more means of displaying the image from the laparoscopic scope and information from one of more other smart devices. The surgical hub may have the capacity of interacting with these multiple displays using an algorithm or control program that enables the combined display and control of the data distributed across the number of displays in communication with the surgical hub. The hub can obtain display control parameter(s) associated with a surgical procedure. The hub may determine, based on the display control parameter, different contents for different displays. The hub may generate and send the display contents to their respective displays. For example, the visualization control parameter may be a progression of the surgical procedure. The surgical hub may determine different display contents for the primary and the secondary displays based on the progression of the surgical procedure.

Abstract: Surgical instruments and control systems therefor are disclosed. A surgical instrument can comprise: a power circuit comprising a power source and a switch, a microcontroller coupled to the power circuit, a handle comprising an attachment portion, and a control circuit in signal communication with the microcontroller. The attachment portion can comprise a first electrical contact in signal communication with the microcontroller. The control circuit can comprise a sensor configured to detect an attachment state of the attachment portion. The control circuit can communicate the detected attachment state to the microcontroller, and the microcontroller can ignore signals from the first electrical contact when the control circuit communicates a detached state. The attachment portion can comprise a second electrical contact coupled to a second power circuit, and the second power circuit can decouple the second electrical contact and the second power source when the sensor detects the detached state.

Abstract: An apparatus includes a body, a motor, a shaft, a stapling assembly, and an electrical potential shifting device. The body includes a firing switch configured to generate a motor drive signal including at least one of a motor activation signal portion or a motor deactivation signal portion. The motor includes a first power terminal and a second power terminal which define an electrical potential energy differential therebetween. The motor is configured to selectively activate and deactivate in response to the electrical potential energy differential. The first power terminal is coupled to a power supply and the second power terminal is coupled to the electrical potential shifting device. The electrical potential shifting device increases the electrical potential energy differential of the motor in response to detecting the motor activation signal portion and decreases the electrical potential energy of the motor in response to detecting the motor deactivation signal portion.
