The present disclosure is directed to end effectors. An end effector includes an outer shaft extending along a longitudinal axis and an inner shaft partially located within the outer shaft. The end effector may include an ultrasonic blade. The inner shaft may include biased and unbiased portions. The inner shaft and outer shaft may be translatable relative to one another. At one translatable position, the biased portion of the inner shaft may be located within the outer shaft and the unbiased portion may be substantially straight along the longitudinal axis. At another translatable position, the biased portion of the inner shaft may be located outside of and distally positioned from the outer shaft such that the biased portion of the inner shaft is bent away from the longitudinal axis.

Surgical instruments with articulating shafts

In one embodiment, a surgical instrument comprises an articulable waveguide. The articulable waveguide may be configured to transmit ultrasonic energy therealong. The articulable waveguide comprises a proximal drive section, an end effector and a first flexible. The proximal drive section is configured to couple to an ultrasonic transducer. The end effector is located at a distal portion of the articulable waveguide. The first flexible section comprises a flex bias and be positioned between the proximal drive section and the end effector. The surgical instrument further comprises a first tine extending longitudinally relative to the articulable waveguide.

Surgical instrument

A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly and an end effector. The body assembly includes a trigger and a casing configured to couple with the transmission assembly. An information transmission system transmits instrument information received from a sensor, for example, to a secure server via a secure gateway connected to the instrument. The instrument may be previously tested on a calibration kit to pre-determine and load surgeon-specific settings onto the instrument prior to use.

Surgical instrument usage data management

An apparatus for delivering therapeutic agent to an eye comprises a body, a cannula, a hollow needle, and an actuation assembly. The cannula extends distally from the body and is sized and configured to be insertable between a choroid and a sclera of a patient's eye. The actuation assembly is operable to actuate the needle relative to the cannula to thereby drive a distal portion of the needle along an exit axis that is obliquely oriented relative to the longitudinal axis of the cannula. The cannula may be inserted through a sclerotomy incision to position a distal end of the cannula at a posterior region of the eye, between the choroid and sclera. The needle may be advanced through the choroid to deliver the therapeutic agent adjacent to the potential space between the neurosensory retina and the retinal pigment epithelium layer, adjacent to the area of geographic atrophy.

Method and apparatus for suprachoroidal administration of therapeutic agent

A method for determining motional branch current in an ultrasonic transducer of an ultrasonic surgical device over multiple frequencies of a transducer drive signal. The method may comprise, at each of a plurality of frequencies of the transducer drive signal, oversampling a current and voltage of the transducer drive signal, receiving, by a processor, the current and voltage samples, and determining, by the processor, the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and the frequency of the transducer drive signal.

Surgical generator for ultrasonic and electrosurgical devices

A surgical hub is for use with a surgical instrument configured to deliver therapeutic energy to tissue at a surgical site of a surgical procedure. The surgical hub comprises: a hub enclosure, comprising a docking station including a docking port comprising data and power contacts; and a combo generator module removably retainable in the docking station. The combo generator module comprises: an ultrasonic energy generator component; a radio frequency (RF) energy generator component; a smoke evacuation component; and a connection port. At least one of the ultrasonic energy generator component and the radio frequency (RF) generator component are couplable to the surgical instrument through the connection port. The combo generator module further comprises at least one smoke evacuation component, configured to evacuate smoke generated by an application of therapeutic energy to the tissue by the surgical instrument.

Computer implemented interactive surgical systems

A generator comprising an interface and a control circuit is disclosed. The interface is to electrically couple to an ultrasonic surgical instrument comprising a switch. The switch is configurable between a first switch state and a second switch state. The control circuit is to provide a continuous drive signal to the ultrasonic surgical instrument based on the switch being in the first switch state. The control circuit is to provide a pulsed drive signal to the ultrasonic surgical instrument based on the switch being in the second switch state.

Generator for use with an ultrasonic surgical instrument

A system configured to control operation of an ultrasonic surgical instrument is disclosed. The system comprises a generator configured to generate a signal, and a computer communicably coupled to the generator. The computer is configured to receive a first set of variables corresponding to a first signal at a first power level of the instrument, evaluate the first set of variables with a model to generate a first output, wherein the first output comprises a value between the first set of variables and a condition set, and wherein the condition set comprises a plurality of conditions that correspond to a plurality of responses, determine the first output meets a first threshold value for a first condition; determine a first response corresponding to the first condition, wherein the first response is a second power level for the instrument, and transmit the second power level to the generator for a second signal.

Switch arrangements for ultrasonic surgical instruments

Method and apparatus for subretinal administration of therapeutic agent

An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.

Sterile field interactive control displays

Various embodiments are directed to a method of driving an end effector coupled to an ultrasonic drive system of a surgical instrument. The method comprises generating at least one electrical signal. The at least one electrical signal is monitored against a first set of logic conditions. A first response is triggered when the first set of logic conditions is met. A parameter is determined from the at least one electrical signal.

Devices and techniques for cutting and coagulating tissue

A control circuit is disclosed that comprises a resistor and a switch network. The switch network is configured to transition between a plurality of states corresponding to a plurality of operational modes of a surgical instrument. In a first phase of a control signal, the control circuit is configured to communicate surgical instrument information to a surgical generator. In the second phase of the control signal and when the at least one switch of the switch network is in a first state of the plurality of states, the control circuit is configured to provide an output corresponding to one of the plurality of states. In the second phase of the control signal and when the at least one switch of the switch network is in a second state of the plurality of states, the control circuit is configured to provide a second output.

A surgical instrument includes a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body. The end effector is located at a distal end portion of the shaft assembly. The end effector includes an active feature configured to operate on tissue. The body includes a drive feature operable to drive the active feature of the end effector. The body is removably coupled with the shaft assembly in a connected state and separated from the shaft assembly in a disconnected state.
