FARADAY CAGE FOR DIGITAL SET SCREW PROBE READER
A medical implant identification system is disclosed. The implant identification system may include a probe reader extending from a proximal end to a distal end and the distal end may include a faraday cage. The probe reader may be in communication with an operating room computer and/or a display. The implant identification system may include at least one digital set screw comprising an antenna disposed in an antenna portion of the digital set screw. In various embodiments, the faraday cage may have a size and shape corresponding to a size and shape of the antenna portion of the digital set screw. Additionally, the antenna may be configured to transmit identity information to the probe reader, and the identify information may be displayed by the display and/or stored in a data store of the operating room computer.

Various aspects of a generator, ultrasonic device, and method for estimating and controlling a state of an end effector of an ultrasonic device are disclosed. The ultrasonic device includes an electromechanical ultrasonic system defined by a predetermined resonant frequency, including an ultrasonic transducer coupled to an ultrasonic blade. A control circuit measures a complex impedance of an ultrasonic transducer, wherein the complex impedance as defined as
The control circuit receives a complex impedance measurement data point and compares the complex impedance measurement data point to a data point in a reference complex impedance characteristic pattern. The control circuit then classifies the complex impedance measurement data point based on a result of the comparison analysis and assigns a state or condition of the end effector based on the result of the comparison analysis. The control circuit estimates the state of the end effector of the ultrasonic device and controls the state of the end effector of the ultrasonic device based on the estimated state.
WIRELESSLY TRIGGERED DEVICE
A wirelessly triggered device for implantation in vivo is disclosed herein. In a described embodiment, the wirelessly triggered device comprises an electrically conductive suture; and an electronic circuit coated with a biocompatible encapsulating material and communicatively coupled to the electrically conductive suture, the electronic circuit arranged to convert a received wireless triggering signal into an electrical signal for passing through the conductive suture. A reader for use with the device and an electrically conductive surgical thread is also disclosed, among other aspects.
METHOD FOR OPERATING SURGICAL INSTRUMENT SYSTEMS
A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.
HEAD STABILIZATION SYSTEM WITH SENSING FEATURES
A head stabilization system useable for stabilizing a head of a patient during a medical procedure includes a sensor assembly and a connection assembly connected with a head fixation device. The sensor assembly includes one or more sensors positioned on the head fixation device for detecting one or more characteristics of the head fixation device. The connection assembly receives and processes the detected characteristic to provide feedback of the detected characteristic. The head fixation device can be adjusted or modified based on the provided feedback.
Apparatuses and methods for monitoring tendons of steerable catheters
Methods and apparatuses for detecting tension on a tendon and/or mechanical deformation (e.g., breakage) of one or more steering tendon of a steerable and flexible articulating device. Theses apparatuses may have one or more tendons that are each electrically conductive and configured to steer the apparatus when tension is applied to the proximal end of the tendon. Tension and/or breakage (or other deformation) of one or more of these tendons may be detected by monitoring the electrical resistance of the tendons.

A method for controlling an operation of an ultrasonic blade of an ultrasonic electromechanical system is disclosed. The method includes providing an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade via an ultrasonic waveguide; applying, by an energy source, a power level to the ultrasonic transducer; determining, by a control circuit coupled to a memory, a mechanical property of the ultrasonic electromechanical system; comparing, by the control circuit, the mechanical property with a reference mechanical property stored in the memory; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the comparison of the mechanical property with the reference mechanical property.
Tissue specimen removal device, system and method
A tissue specimen removal device comprises a specimen bag; a flexible ring, the flexible ring configured to form a top opening of the specimen bag; a cannula assembly comprising: an inner tube portion and an outer tube portion. The device may further comprise a connector carrier, the connector carrier configured to retain at least one connector housing, the at least one connector housing comprising one or more connector portions and reside within an interior of the connector carrier, and wherein the connector carrier can be moved from a position within the cannula assembly to outside the cannula assembly.
BIOABSORBABLE STAPLE COMPRISING MECHANISMS FOR SLOWING THE ABSORPTION OF THE STAPLE
A surgical staple comprising a substrate and one or more coatings which slows the bioabsorption of the substrate. The coating can be selected so as to affect the environment surrounding the staple once the staple is implanted in the patient. The effect on the environment can cause the bioabsorption to occur within a desired time frame.
Temperature control of ultrasonic end effector and control system therefor
A generator, ultrasonic device, and method of determining a temperature of an ultrasonic blade are disclosed. A control circuit coupled to a memory determines an actual resonant frequency of an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade by an ultrasonic waveguide. The actual resonant frequency is correlated to an actual temperature of the ultrasonic blade. The control circuit retrieves from the memory a reference resonant frequency of the ultrasonic electromechanical system. The reference resonant frequency is correlated to a reference temperature of the ultrasonic blade. The control circuit then infers the temperature of the ultrasonic blade based on the difference between the actual resonant frequency and the reference resonant frequency.
