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.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

A medical robot system, including a robot coupled to an effectuator element with the robot configured for controlled movement and positioning. The system may include a transmitter configured to emit signals, and the transmitter is coupled to an instrument coupled to the effectuator element. The system may further include a motor assembly coupled to the robot and a plurality of receivers configured to receive the signals emitted by the transmitter. A control unit is coupled to the motor assembly and the plurality of receivers, and the control unit is configured to supply instruction signals to the motor assembly. The instruction signals can be configured to cause the motor assembly to selectively move the effectuator element and is further configured to (i) calculate a position of the transmitter; (ii) display the position of the at least one transmitter; and (iii) selectively control actuation of the motor assembly.

Devices, systems, and methods for automatically exchanging a first end-effector on a robot arm with a second end-effector housed in a docking station. The first end-effector has a clamp that either engages or disengages the robot arm based upon an application of force of the robot arm onto the end-effector. The clamp has a spring loaded clip that disengages the first end-effector to allow the robot arm to move away from the released first end-effector. The robot arm is configured to automatically move to a port of a docking station housing the desired second end-effector using magnetic coils on the robot arm and the docking station to guide the robot arm.

A method of automatically evaluating resection accuracy, is provided. The method includes preoperatively obtaining a first image of a volume of patient tissue using an imaging modality configured according to a scanning parameter, and storing the scanning parameter. An identifier of a target region corresponding to a target portion of the volume is received and stored in association with the first image. A second image is obtained of a resected tissue sample from the volume, using the imaging modality configured according to the scanning parameter. Based on a comparison of the first image and the second image, a determination is made whether the entire target region is represented in the second image. The method includes controlling an output device to present an indication, based on the determination, of whether the tissue sample contains the entire target portion.

Devices, Systems, and Methods for controlled movement of the robot system. The surgical robot system may include a robot having a robot base, a robot arm coupled to the robot base, and an end-effector coupled to the robot arm. The robot may include a plurality of omni-directional wheels affixed to the robot base allowing multiple-axis movement of the robot. The robot may further include sensors for detecting a desired movement of the robot base and a control system responsive to the plurality of sensors for controlling the multiple-axis movement of the robot by actuating two or more of the plurality of omni-directional wheels.

The present invention relates to a tracking reference structure for localizing and tracking an object by means of a medical tracking system, said structure comprising: —a first part (1) which forms a support structure for at least one tracking marker (3); and—a second part (2) which is configured to be fixed to said object, wherein a positionally fixed connection between the first part (1) and the second part (2) is established by means of an interface comprising at least one resiliently articulated element (4) on the first part (1) and/or second part (2), which engage(s) with the respective other part (2, 1), and wherein the resiliently articulated element (4) is configured such that its restoring spring force alone is already sufficient to positionally fix the connection. The present invention also relates to a tracking reference system comprising such a tracking reference structure which in turn comprises at least one first part (1), wherein any additional first part(s) (1) support(s) a different type of tracking marker (3) and said different first parts (1) can be interchangeably connected to the second part (2), and wherein the tracking markers (3) of each of said different first parts (1) are in particular placed in the same spatial position when being coupled to the second part (2).

Presented herein are systems, methods, and architectures related to augmented reality (AR) surgical visualization of one or more dual-modality probe species in tissue. As described herein, near infrared (NIR) images are detected and rendered in real time. The NIR images are registered and/or overlaid with one or more radiological images (e.g., which were obtained preoperatively/perioperatively) by a processor [e.g., that uses an artificial neural network (ANN) or convolutional neural network (CNN) reconstruction algorithm] to produce a real-time AR overlay (3D representation). The AR overlay is displayed to a surgeon in real time. Additionally, a dynamic motion tracker tracks the location of fiducial tracking sensors on/in/about the subject, and this information is also used by the processor in producing (e.g., positionally adjusting) the AR overlay. The real-time AR overlay can improve surgery outcomes, for example, by providing additional real-time information about a surgical site via an intuitive visual interface.

A biopsy marker that can emit near infrared fluorescence for location of a biopsy site. The biopsy marker has a body formed from a polymer and a quantity of a near infrared fluorescent dye, such as indocyanine green, embedded in the polymer. A near infrared energy source is used to excite the near infrared fluorescent dye. A near infrared energy detector is used to detect any near infrared emissions from the biopsy marker. As a result, any and all biopsy markers within the field of view may be readily identified and located so that the tissue locations can be surgical removed if the tissue samples indicate a risk of cancerous tissue.
