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.

Cutting tools, systems and methods for navigated procedures are provided. A cutting tool (e.g. oscillating blade, etc.) for a power tool has an optically trackable feature in a defined positional relationship relative to a cutting feature of the cutting tool. The trackable feature may include reflective material applied to a surface (e.g. a recessed blade surface). The trackable feature is be imaged by a camera integral with or attached to the power tool and provided to a computing unit of a navigation system to determine a relative pose of the cutting feature and camera. The camera may also track a patient's bone such that the computing unit may determine a relative position of the bone and camera. The unit then computes a relative pose of the cutting feature with respect to the patient's bone and provides same for determining display information and/or to a robotic controller for procedural control.

Systems and methods for visualizing navigation of a medical device with respect to a target using a live fluoroscopic view. The methods include displaying, in a screen, a three-dimensional (3D) view of a 3D model of a target from the perspective of a medical device tip. The methods also include displaying, in the screen, a live two-dimensional (2D) fluoroscopic view showing a medical device, and displaying a target mark, which corresponds to the 3D model of the target, overlaid on the live 2D fluoroscopic view. The methods may include determining whether the medical device tip is aligned with the target, displaying the target mark in a first color if the medical device tip is aligned with the target, and displaying the target mark in second color different from the first color if the medical device tip is not aligned with the target.

A medical tool includes a handle, a tubular member, and a bendable shape memory element (SME). The tubular member is attached to and extends from the handle and is configured to be inserted into an orifice of a patient. The tubular member has a distal-end section that is configured to be bent so as to perform a medical procedure in the orifice. The bendable shape memory element (SME) is coupled to the distal-end section of the tubular member, wherein the SME is configured to straighten when heated into a pre-formed shape, thereby straightening the distal-end section.

A method for magnetic tracking of a flexible catheter device or another flexible elongated device, the method comprising: receiving by a host server a plurality of sensed values of a local magnetic field, sensed by a respective plurality of sensors, wherein the host server is optionally included in a controller of the sensors, the sensors are located along a flexible tube of a device, wherein the sensed values are at least partially due to at least one alternating magnetic field generated by at least one magnetic field generator, the source amplitude and frequency of each generated magnetic field are given to the host server; and calculating by the host server, based on the sensed magnetic field values and the given source amplitude and frequency of each generated magnetic field, a localization of the flexible tube.

A surgical system includes an arm extending from the base and having a distal end configured to be coupled to a tool, a first marker coupled in fixed relation to the base, and a tracking system. The tracking system is configured to collect first data indicative of a position of the first marker and collect second data indicative of a position an anatomical feature of a patient. The surgical system also includes a processor configured to calculate a position of the tool relative to the anatomical feature based on the first data and the second data.

A system and method for a procedure that can be performed on any appropriate subject. Procedures can include assembling any appropriate work piece or installing members into a work piece, such as an airframe, autoframe, etc. Regardless of the subject, tracking a substantially small tracking device in a plurality of degrees of freedom is provided. The tracking device can be positioned on or be formed in an instrument to be tracked.

Systems, methods, and instrumentalities are disclosed for switching a control scheme to control a set of system modules and/or modular devices of a surgical hub. A surgical hub may determine a first control scheme that is configured to control a set of system modules and/or modular devices. The surgical hub may receive an input from one of the set of modules or a device located in an OR. The surgical hub may make a determination that at least one of a safety status level or an overload status level of the surgical hub is higher than its threshold value. Based on at least the received input and the determination, the surgical hub may determine a second control scheme to be used to control the set of system modules. The surgical hub may send a control program indicating the second control scheme to one or more system modules and/or modular devices.

An ENT tool has a tool chassis having a chassis channel and a tool chassis distal end. A tubular probe is dimensioned to be inserted into a human patient orifice, the probe is rotatable about a probe axis of symmetry, and the probe has a probe proximal end rotatingly connected to the tool chassis distal end. A balloon insertion mechanism is slidingly located within the chassis channel, and is configured to fixedly accept a balloon sinuplasty mechanism penetrating the tubular probe. A guidewire adjustment section is fixedly attached to the balloon insertion mechanism, and the section has a rotatable enclosure. A plurality of rollers are disposed within the enclosure and are configured so that on rotation of the enclosure the rollers grip and rotate a guidewire positioned between the rollers, and, absent rotation of the enclosure, release the guidewire and permit distal and proximal translation of the guidewire.

The disclosed technology includes a medical probe comprising a tubular shaft extending along a longitudinal axis and including a proximal end and a distal end. The medical probe further comprises an expandable basket assembly proximate the distal end of the tubular shaft. The basket assembly comprises a plurality of C-shaped spines and one or more electrodes coupled to each of the spines, each electrode defining a lumen through the electrode so that a spine extends through the lumen of each of the one or more electrodes. The spines converge at a central spine intersection at a distal end of the basket assembly. Each spine comprises a respective end connected to the distal end of the tubular shaft.
