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

A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, and an end effector. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The body comprises a pivotal trigger. The shaft couples the end effector and the body together. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with the ultrasonic transducer. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue. Pivotal movement of the trigger causes movement of the clamp arm. The trigger includes a compliant feature configured to limit the amount of force delivered to tissue by the clamp arm. The flexible feature may comprise a flexible band, living hinge, a series of living hinges, or a flexible tab.

Handpiece and blade configurations for ultrasonic surgical instrument

A surgical instrument includes an ultrasonic transducer, an ultrasonic transmission waveguide extending from the ultrasonic transducer, and an ultrasonic blade acoustically coupled to the ultrasonic transmission waveguide. The ultrasonic blade includes a base and a curved body extending distally from the base. The curved body includes a tissue-treating surface extending on a first side of the curved body and a curved edge extending on a second side of the curved body opposite the first side. The curved edge has a proximal end and a distal end, wherein the proximal end is offset from the distal end in a first direction, wherein the proximal end is offset from the distal end in a second direction, and wherein the first direction is perpendicular to the second direction.

Ultrasonic surgical blade for use with ultrasonic surgical instruments

A surgical instrument comprising a waveguide, an end effector, and an electrical switch is disclosed. The waveguide comprises a proximal end and a distal end, wherein the proximal end is configured to couple to an ultrasonic transducer and one output of a radio frequency (RF) generator. The end effector may comprise an ultrasonic blade and a clamp arm. The ultrasonic blade is mechanically coupled to the distal end of the waveguide and electrically coupled to the waveguide. The clamp arm comprises a movable jaw member electrically coupled to another output of the RF generator. The electrical switch is operable to cause the surgical instrument to deliver electrical current from the RF generator to the movable jaw member for a first period, and to cause the surgical instrument to deliver ultrasonic energy to the ultrasonic blade for a second period.

Ultrasonic and electrosurgical devices

A surgical apparatus comprises an instrument body, an end effector, and a control module. The end effector is in communication with the handle assembly. The end effector is operable for use in a surgical procedure. The control module is in communication with the end effector. The end effector with the control module is able to deliver surgical energy as well as nerve excitation energy to a surgical site. A surgeon may detect stimulation of nervous tissue by visually observing the tissue twitch, and may adjust surgical technique accordingly. A sensor may be used to detect excitation of nervous tissue based on excitation caused by the nerve excitation energy.

Surgical instrument with nerve detection feature

An ultrasonic clamp coagulator assembly configured to permit selective cutting, coagulation and clamping of tissue during surgical procedures. The assembly includes a blade having a first and second tissue contact surface and a clamping mechanism, including a first and second clamp arm pivotally mounted at the distal portion of the instrument for clamping tissue between first and second tissue contact surfaces, respectively.

Ultrasonic device for cutting and coagulating

An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. A tension release mechanism is associated with the tension element.

Implantable restriction system tension release mechanism

A surgical apparatus includes an end effector having an ultrasonic blade, a clamp arm, and a clamp pad. The end effector applies ultrasonic energy at the blade. The clamp arm pivots relative to the blade. The clamp pad is positioned on the clamp arm adjacent to the blade. The clamp arm includes a latching feature to retain the clamp pad relative to the clamp arm to prevent the clamp pad from moving laterally, longitudinally, and perpendicularly relative to the clamp arm.

Clamp arm features for ultrasonic surgical instrument

Various forms are directed to a method for operating an ultrasonic surgical instrument. The ultrasonic surgical instrument may be activated by generating a drive signal provided to the ultrasonic drive system to drive the end effector. A plurality of input variables may be applied to a multi-variable model to generate a multi-variable model output, where the multi-variable model output corresponds to an effect of the ultrasonic instrument on tissue. The plurality of input variables may comprise at least one variable describing the drive signal and at least one variable describing a property of the ultrasonic surgical instrument. When the multi-variable model output reaches a threshold value, feedback may be generated indicating a corresponding state of at least one of the ultrasonic surgical instrument and tissue acted upon by the ultrasonic surgical instrument.
