Surgical clip applier comprising adaptive control in response to a strain gauge circuit
A surgical clip applier comprising an electric motor system is disclosed. The electric motor system is configured to drive a clip firing system of the surgical clip applier. The surgical clip applier further comprises a control system configured to control the electric motor system. The control system is configured to monitor a strain gauge circuit to assess the crimping force experienced by the clip firing system. In at least one instance, one or more strain gauges are mounted to a drive shaft and/or jaw of the clip firing system. The control system modifies the operation of the surgical clip applier when the voltage of the strain gauge circuit exceeds and/or falls below a threshold. In at least one instance, the control system modulates the width, or duration, of voltage pulses applied to the electric motor system to control the speed of the electric motor system.
AESTHETIC METHOD OF BIOLOGICAL STRUCTURE TREATMENT BY MAGNETIC FIELD
In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.
Electrode for a system for heating biological tissue via RF energy
An electrode is disclosed for use in a system for heating biological tissue via RF energy. The electrode comprises a plurality of electrically conductive pins projecting from, and in electrical contact with, an electrically conductive common base. The base is connectible to a source of RF energy and the spaced ends of the pins remote from the base have contact regions for introducing RF energy from the source into the biological tissue. Each contact region is sufficiently small to achieve uniform dielectric heating in the biological tissue beneath the contact region at the frequency of the applied RF energy.

An electrosurgical system can include an electrosurgical generator, a feedback circuit or controller, and an electrosurgical tool. The feedback circuit can provide an electrosurgery endpoint by determining the phase end point of a tissue to be treated. The electrosurgical system can include more than one electrosurgical tool for different electrosurgical operations and can include a variety of user interface features and audio/visual performance indicators. The electrosurgical system can also power conventional bipolar electrosurgical tools and direct current surgical appliances.
Surgical clip applier comprising an automatic clip feeding system
A surgical clip applier is disclosed which is configured to automatically feed a clip from a clip cartridge once the surgical clip applier is positioned in the patient.
METHOD FOR CONTROLLING AN ENERGY MODULE OUTPUT
A method for controlling an output of an energy module of a modular energy system. The energy module can comprise a plurality of amplifiers configured to generate a drive signal at a frequency range and a plurality of ports coupled to the plurality of amplifiers. The method includes determining to which port of the plurality of ports the surgical instrument is connected, selectively coupling an amplifier of the plurality of amplifiers to the port of the plurality of ports to which the surgical instrument is connected, and controlling the amplifier to deliver the drive signal for driving the energy modality to the surgical instrument through the port.
ROBOTIC COLPOTOMY SYSTEMS
A robotic colpotomy system includes a robotic arm, an instrument drive unit supported on the robotic arm, and a uterine manipulator supported on the robotic arm. The uterine manipulator is coupled to the instrument drive unit and has an elongated shaft assembly that supports a colpotomy assembly on a distal end portion thereof. The colpotomy assembly includes a colpotomy cup and extends distally to a distal tip. The various components of the robotic colpotomy system are positioned or movably positioned to help effectuate a colpotomy procedure.
Macerating and Aspiration Tool for Intracranial Surgery
A macerating and aspiration tool for removing blood masses from the brain.
THERMAL CUTTING-ASSISTED TISSUE RESECTION DEVICES AND SYSTEMS
A tissue resection device includes a handpiece and an end effector assembly extending distally from the handpiece. The end effector assembly includes an outer shaft defining a longitudinal axis and including a window defined therethrough towards a distal end thereof. The end effector assembly further includes an inner member rotationally disposed within the outer shaft. The inner member includes a proximal body portion and a distal cutting portion. The proximal body portion is coaxially disposed on the longitudinal axis and rotatable thereabout. The distal cutting portion includes an offset portion that is radially offset from the longitudinal axis and is configured to orbit about the longitudinal axis. At least a portion of the distal cutting portion is a thermal cutting element configured to heat in response to application of electrical energy thereto.
INDUCTIVE POWER JOINT ALLOWING UNRESTRICTED ROTATION
A user-held or otherwise supported electrosurgical device can include an endpiece, a fixed first coil or other electromagnetic energy transmitter or receiver and a rotatable second coil or other electromagnetic energy transmitter or receiver wirelessly energized by the first coil. The rotatable second coil can be affixed to a rotatable member extending distally from the endpiece. This can permit unrestricted rotation without being encumbered by wiring or electrical contacts across a plane of rotation.
