A system for controlling ablation treatment and visualization is disclosed where the system comprises a tissue ablation instrument having one or more deployable stylets and a first electromagnetic sensor and an ultrasound imaging instrument which may be configured to generate an ultrasound imaging plane and further having a second electromagnetic sensor. An electromagnetic field generator may also be included which is configured for placement in proximity to a patient body and which is further configured to generate an output indicative of a position the first and second electromagnetic sensors relative to one another. Also included is a console in communication with the ablation instrument, ultrasound imaging instrument, and electromagnetic field generator, wherein the console is configured to generate a representative image of the tissue ablation instrument oriented relative to the ultrasound imaging plane and an ablation border or cage based upon a deployment position of the one or more stylets.

Techniques for automated rotation of a needle in a computer-assisted system include an end effector having a drive mechanism configured to be coupled to a curved needle and configured to rotationally actuate the curved needle along an arcuate path and a control unit coupled to the drive mechanism. The control unit is configured to, in response to receiving a first input, cause the drive mechanism to rotationally actuate the curved needle by a first preset rotation amount along the arcuate path, and, in response to receiving a second input, cause the drive mechanism to rotationally actuate the curved needle by a second preset rotation amount along the arcuate path.

A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints. three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features. surgical plan comprising the patient-specific implantation geometry may then be displayed.

A method of treating a patient with a therapeutic laser pulse includes applying a cooling mechanism to a first skin area, cooling a target skin area within the first the skin area from a first surface temperature to a second temperature through application of the cooling mechanism prior to application of the therapeutic laser pulse, initiating application of the therapeutic laser pulse at a first timepoint, while continuing to apply the cooling mechanism, determining a surface temperature of the target skin area a plurality of times during application of the therapeutic laser pulse at a refresh rate of 25 Hz to 400 Hz, and terminating the application of the therapeutic laser pulse at a second timepoint, based on the surface temperature determinations. Each of the plurality of surface temperature determinations occurs during a single therapeutic laser pulse duration from the first time point to the second timepoint.

The present disclosure provides a system for enabling autonomous or semi-autonomous surgical operations. The system comprises: one or more processors that are individually or collectively configured to: process an image data stream comprising one or more images of a surgical site; fit a parametric model to a tissue surface identified in the one or more images; determine a direction for aligning a tool based in part on the parametric model; determine an optimal path for automatically moving the tool to perform a surgical procedure at the surgical site; and generate one or more control signals for controlling i) a movement of the tool based on the optimal path and ii) a tension force applied to the tissue by the tool during the surgical procedure.

A number of improvements are provided relating to computer aided surgery. The improvement relates to both the methods used during computer aided surgery and the devices used during such procedures. Some of the improvement relate to controlling the selection of which data to display during a procedure and/or how the data is displayed to aid the surgeon. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled automatically to improve the efficiency of the procedure. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure.

A smart tourniquet for self-administering a medication is provided. When a patient needs to inject themselves with a medication, intravenously, called an “infusion,” the patient wears the smart tourniquet around their arm and tightens the device. While the patient is using the smart tourniquet, the device automatically records the date and time of the infusion, called a “timestamp”. The patient can also use the device to record the dosage or “number of units” taken at the time of the infusion. The smart tourniquet can store the timestamp as well as other related information as a record. At a later time, the patient can recall prior records on the smart tourniquet itself. The smart tourniquet can also be synchronized with an application and the records can be downloaded for review by the patient, nurse or doctor to render accurate and timely care.

The invention relates to an assembly for use in minimally invasive surgical procedures, including bone implant fixation procedures. The assembly is configured to provide a faster and more accurate measurement of depth of holes for placement of bone screws and fasteners. The assembly includes a guidewire having a deployable distal hook member configured to securely anchor into a desired position relative to a hole drilled in a bone and thereby provide an accurate datum for a measuring instrument for determining a depth of the hole for subsequent screw placement. The assembly further includes a surgical depth instrument to cooperatively function with the guidewire and obtain one or more measurements while operably coupled to the guidewire.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.

Embodiments of the present disclosure generally relate to systems and methods for calibrating light-emitting diode (LED) light engines. The systems and methods described herein include characterizing the performance of a red-green-blue (RGB) LED light engine so as to enable the display of calibrated, dimensionless output values that accurately reflect a perceived brightness of illumination generated by the light engine for a specific output color.
