SYSTEMS AND METHODS FOR INTRAOPERATIVE RE-REGISTRATION
A re-registration method includes receiving a first image depicting a reference frame attached to a patient and oriented in a first pose relative to the patient, the first image obtained by an imaging device mounted to a movable support that has been locked in a selected pose; receiving a second image depicting the reference frame oriented in a second pose relative to the patient, the second image obtained by the imaging device with the movable support locked in the selected pose; and updating a registration between the reference frame and the patient to reflect that the reference frame has been moved from the first pose to the second pose.
SURGICAL INSTRUMENT COMPRISING A SENSOR SYSTEM
A surgical instrument configured for use in a surgical procedure is disclosed herein. The surgical instrument comprises a housing, a first sensor configured to detect a condition of the surgical instrument, and a second sensor configured to detect the condition of the surgical instrument. The surgical instrument further comprises a processor, wherein the processor is located within the housing. The first sensor and the second sensor are in signal communication with the processor. The processor receives a first signal from the first sensor and a second signal from the second sensor. The processor is configured to utilize the first signal and the second signal to determine the condition and communicate instructions to the surgical instrument during the surgical procedure in view of the condition.
Method of using reinforced flexible circuits with multiple sensors to optimize performance of radio frequency devices
A method implemented by a surgical instrument is disclosed. The surgical instrument includes first and second jaws and a flexible circuit including multiple sensors to optimize performance of a radio frequency (RF) device. The flexible circuit includes at least one therapeutic electrode couplable to a source of RF energy, at least two sensing electrodes, and at least one insulative layer. The insulative layer is positioned between the at least one therapeutic electrode and the at least two sensing electrodes. The method includes contacting tissue positioned between the first and second jaws of the surgical instrument with the at least one therapeutic electrode and at the least two sensing electrodes; sensing signals from the at least two sensing electrodes; and controlling RF energy delivered to the at least one therapeutic electrode based on the sensed signals.
Selected Image Acquisition Technique To Optimize Specific Patient Model Reconstruction
A system and a method are disclosed that allow for generation of a model or reconstruction of a model of a subject based upon acquired image data. The image data can be acquired in a substantially mobile system that can be moved relative to a subject to allow for image acquisition from a plurality of orientations relative to the subject. The plurality of orientations can include a first and final orientation and a predetermined path along which an image data collector or detector can move to acquire an appropriate image data set to allow for the model of construction.
END-EFFECTORS FOR SURGICAL ROBOTIC SYSTEMS HAVING SEALED OPTICAL COMPONENTS
An end-effector for a surgical robot system may include an end-effector body and an optical sub-assembly. The optical sub-assembly may include a housing coupled to the end-effector body, the housing including a threaded portion. The optical sub-assembly may further include a window that is transparent to a predetermined range of light radiation wavelengths. The optical sub-assembly may further include a gasket disposed between the housing and the window. The optical sub-assembly may further include a threaded ring disposed over the window and threadedly engaging the threaded portion of the housing, the threaded ring compressing the gasket between the window and the housing to form a seal between the window and the housing. The optical sub-assembly may further include a light emitter configured to emit light in the predetermined range of light radiation wavelengths through the window.
Method and apparatus to account for transponder tagged objects used during clinical procedures employing a shielded receptacle with antenna
Medical procedure related objects (e.g., instruments, supplies) tagged with transponders (e.g., RFID transponders, dumb transponders) are accounted for in a medical or clinical environment via an accounting system using a number of antennas and interrogators/readers. A first set of antennas and RFID interrogator(s) interrogate portions of the environment for RFID tagged objects, for example proximate a start and an end of a procedure. Shielded packaging and/or shielded receptacles shield tagged objects, preventing interrogation except for those objects in unshielded portions of the environment. A shielded receptacle may include an antenna to interrogate the contents thereof in a relatively noise-free environment. A data store may maintain information including a current status or count of each instrument or supply, for instance as checked in or checked out. A handheld antenna and/or second set of antennas interrogates a body of a patient for retained instruments or supplies tagged with dumb transponders.
Method for determining the position of a rotatable jaw of a surgical instrument attachment assembly
A method for determining the position of a rotatable jaw of an attachment relative to a non-rotatable jaw is disclosed. The method comprises assembling the attachment to a surgical robot, rotating a first rotatable driver of the robot to align the first driver with a first rotatable drive of the attachment, and rotating a second rotatable driver of the robot to align the second driver with a second rotatable drive of the attachment. The method further comprises evaluating the amount of rotation required to align the first driver with the first drive and the amount of rotation required to align the second driver with the second drive, calculating a difference between the amount of rotation of the first driver and the amount of the rotation of the second driver, and determining the position of the rotatable jaw relative to the non-rotatable jaw based on the calculated difference.
End-effectors for surgical robotic systems having sealed optical components
An end-effector for a surgical robot system may include an end-effector body and an optical sub-assembly. The optical sub-assembly may include a housing coupled to the end-effector body, the housing including a threaded portion. The optical sub-assembly may further include a window that is transparent to a predetermined range of light radiation wavelengths. The optical sub-assembly may further include a gasket disposed between the housing and the window. The optical sub-assembly may further include a threaded ring disposed over the window and threadedly engaging the threaded portion of the housing, the threaded ring compressing the gasket between the window and the housing to form a seal between the window and the housing. The optical sub-assembly may further include a light emitter configured to emit light in the predetermined range of light radiation wavelengths through the window.
Shape sensor systems with redundant sensing
A method of operating a shape sensing apparatus comprises receiving first shape data from a first shape sensor section including a first elongated optical fiber section extending between a first location coupled to a reference fixture and a second location coupled to a first target fixture. The method further comprises receiving second shape data from a second shape sensor section including a second elongated optical fiber section extending between a third location coupled to the reference fixture and a fourth location coupled to the first target fixture. The first and third locations are maintained in a first known kinematic relationship, and the second and fourth locations are maintained in a second known kinematic relationship. The method further comprises determining a position of an end portion of the first shape sensor section using the second shape data and using the first and second known kinematic relationships.
