A handheld surgical instrument includes a motor that transmits rotational movement to a drill bit of the handheld surgical instrument. The drill bit extends through a depth measurement module with a depth measurement extension, and a cannula, which extends forward from the drill to measure bore depth. The depth measurement extension is moveably mounted to the drill so as to extend into the rotor bore of the motor. As the drill advances forward, the depth measurement extension remains static. As a result of the advancement of the drill, the rotor extends over the proximal end of the depth measurement extension. A controller is configured to determine a breakthrough time and a breakthrough displacement of the drill bit based on displacement data and derived signals. The controller is further configured to determine a proper length of a screw to be used in a fixation surgical procedure based on the displacement data.

The apparatus and method for hemostasis that informs the provider as to whether the appropriate magnitude of pressure is being applied to a puncture site on a patient. A visual pulse indicator can visually convey whether or not there is proper blood flow at the puncture site based on the pulsing motion encountered by the visual pulse indicator on the puncture site. The visual pulse indicator can potentially factor in a variety of different input parameters in displaying information that is useful to providers.

The present disclosure provides a method for controlling a surgical instrument. The method includes connecting a power assembly to a control circuit, wherein the power assembly is configured to provide a source voltage, energizing, by the power assembly, a voltage boost convertor circuit configured to provide a set voltage greater than the source voltage, and energizing, by the voltage boost convertor, one or more voltage convertors configured to provide one or more operating voltages to one or more circuit components.

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 firing member motion data describing a motion of the firing member during the open-loop portion of the firing member stroke and may select a firing control program based at least in part on the motion of the firing member during the open-loop portion of the firing member stroke.

An apparatus for use in tissue removal from a body organ is presented. The apparatus comprises a hand-held probe device, a rotating motor device and a connection assembly configured for removably interconnecting between the hand-held probe device and the rotating motor device. The hand-held probe device is disposable and comprises a housing having proximal and distal ends, a rotatable cutting tool extending distally from the distal end of the housing and being configured for cutting and removing tissue during rotation, and a transmission assembly passing inside the housing between the proximal and distal ends and being configured for transmitting rotational power to the rotatable cutting tool. The connection assembly is configured for engaging between the rotating motor device and the transmission assembly to thereby controllably rotate the cutting tool and remove tissue. In some embodiments, the apparatus includes a control unit for controlling operation of the apparatus, the control unit comprises an activation mechanism for activating the rotatable cutting tool, and a controller configured for operating the activation mechanism to generate a single fixed activation signal of a known intensity and duration during a predetermined time interval, thereby restricting operation of the cutting tool during the time interval to the single activation signal only.

A surgical instrument comprising a handle, a shaft rotatable relative to the handle, and an articulation joint rotatable relative to the shaft. The surgical instrument further comprises a motor-driven articulation system including articulation controls which are flipped by a control system of the surgical instrument when the shaft is rotated upside down relative to the handle.

A method and system for controlling at least one robotically controlled surgical tool via vocal activation include detecting a vocal command generated by a surgeon, converting said at least one surgeon in said surgical setting via said voice sensor. The vocal command is converted to operative instructions associated with a robotically controlled surgical tool to generate instructions according to a predetermined set of rules including at least one of a no fly zone rule and collision prevention rule.
