A digital loupe system is provided which can include a number of features. In one embodiment, the digital loupe system can include a stereo camera pair and a distance sensor. The system can further include a processor configured to perform a transformation to image signals from the stereo camera pair based on a distance measurement from the distance sensor and from camera calibration information. In some examples, the system can use the depth information and the calibration information to correct for parallax between the cameras to provide a multi-channel image. Ergonomic head mounting systems are also provided. In some implementations, the head mounting systems can be configurable to support the weight of a digital loupe system, including placing one or two oculars in a line of sight with an eye of a user, while improving overall ergonomics, including peripheral vision, comfort, stability, and adjustability. Methods of use are also provided.

A body-worn device for flexibly supporting a body part such as the head in a hunched over position such as when a surgeon performs surgery. The device can include a head harness connected to a torso harness by a specialized oblong variable stiffness beam that extends upwardly along the back of the spine of the wearer. The beam can include a variable stiffness member having a complex tapered geometry. The member can be made from a unitary piece of fiber composite material wherein the orientations of the fibers are varied to provide both bending and torsional strength and stiffness that varies along the length of the member. The beam and harnesses can include a plurality of interconnected mechanisms to provide greater adjustability.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

A surgical hub for controlling a display outside a sterile field may be provided. A first message may be sent that may instruct a first display that may be located within the sterile field to display a first contextual data. A user gesture from a device associated with the first display may be determined. The user gesture may indicate that a second contextual data may be displayed on a second display outside the sterile field. A second message may be sent that may instruct the second display to show the second contextual data.

A power supply unit for a surgical instrument operated by an electric motor includes a battery-receiving housing separate and spaced apart from the surgical instrument. A fastening means or retainer fastens or retains the power supply unit to a body part of an operator. At least one power supply unit supplies power to at least one motor system. A control and monitoring device performs and/or monitors at least one function. A cable connection connects a cable for electrically coupling the power supply unit to a surgical instrument for operating the motor system thereof and/or for transmitting data and/or operating parameters.

An apparatus is provided for use with a tissue anchor and an anchor driver. The apparatus includes a housing, shaped to define a channel. The channel includes (i) an anchor-storage zone, and (ii) a proximal opening configured to provide access for the anchor driver to the anchor-storage zone. The channel is configured to enable sliding of the tissue anchor therewithin to be stored in the anchor-storage zone. The apparatus also includes a retaining member, shaped to define a cradle for cradling and holding the tissue anchor in the anchor-storage zone. The retaining member includes a pillar pivotable with respect to the cradle, and configured to support the tissue anchor at the cradle. Other embodiments are also described.

Using two or more cameras attached to the eyewear, three-dimensional views with accurate and natural depth perception of the working area can be displayed for users, so that the user can maintain healthy sitting or standing posture while working on patients or objects located below horizontal eye level. Additional functions including eye protection, zoom-in, zoom-out, on-off, lighting control, overlapping, and teleconference capabilities are also supported using electronic, video and audio devices attached to the eyewear. The eyewear can also comprise a face shield designed to protect the user from hazardous droplets, aerosols, harmful wavelengths of light, heat, sparks, flash burn, debris and/or flying objects.
