Various surgical systems are disclosed. A surgical system can include a surgical robot and a surgical hub. The surgical robot can include a control unit in signal communication with a control console and a robotic tool. The surgical hub can include a display. The surgical hub can be in signal communication with the control unit. A facility can include a plurality of surgical hubs that communicate data from the surgical robots to a primary server. To alleviate bandwidth competition among the surgical hubs, the surgical hubs can include prioritization protocols for collecting, storing, and/or communicating data to the primary server.

A surgical retractor includes a part defining a longitudinal axis. A first radiolucent blade is connected with the part. A second radiolucent blade is connected with the part. The blades are independently translatable relative to the part. At least one of the blades includes spaced apart arms that are connected via a member. The member and the arms are relatively disposed in a configuration to guide at least one surgical instrument in a selected orientation relative to a surgical site. Surgical systems, instruments, constructs, implants and methods are disclosed.

A method is provided for determining the shape of a surgical linking device that is to be attached to a bony body structure such as the spinal column based on digitized locations of a plurality of attachment elements engaged to the bony structure. The method is implemented by a computer system through a GUI to generate an initial bend curve to mate with the plurality of attachment elements. The initial bend curve may be simplified based on user input to the GUI to reduce the number of bends necessary to produce a well-fitting linking device and may be altered to help obtain the goals of surgery.

A medical device capable of preventing a circumferential twist and bending of an expansion body expandable in a radial direction and a method for manufacturing an expansion body to be used in the medical device. The medical device includes an outer tube, an expansion body expandable in a radial direction, and a pulling shaft protruding from a distal portion of the outer tube, connected to a distal portion of the expansion body, and slidable with respect to the outer tube. The expansion body includes main struts and sub-struts. Each of the main struts is substantially parallel to an axis when viewed from a radially outer side. Each of the sub-struts includes at least two joint portions joined respectively to two circumferentially adjacent main struts, and at least two of the joint portions are disposed at different positions in an axial direction of the outer tube.

A tissue traction device, system, and method presenting a grasping rail for coupling with a portion of a target tissue at a treatment site to apply a force, such as traction, to the grasped tissue, such as to facilitate performance of a procedure on the target tissue. A tissue traction device, system, and method having a distal support element, a proximal support element, and at least one expansion element extending therebetween. The at least one expansion element is extendable to define a working area for a procedure to be formed on target tissue at a treatment site. Two or more expansion elements may define a working area unimpeded by the expansion elements. The distal support element may be expandable to anchor the tissue traction device with respect to tissue.

Systems, methods, and devices for planning a path are provided. A work volume and one or more no-fly zones may be mapped. The work volume may define a volume in which a robot may access and each of the one or more no-fly zones may define at least one volume in which a robot is restricted from accessing. Information may be received about a position of at least one instrument and a void volume may be calculated based on the position of the at least one instrument. The work volume may be updated to include the void volume to yield an updated work volume. A path may be calculated for a robotic arm of a robot from outside a patient anatomy to within the patient anatomy that is within the updated work volume and avoids the one or more no-fly zones.

A deflection system for deflecting a body lumen that includes a deflection mechanism, wherein the deflection mechanism includes: a beam having a proximal end and a distal end, wherein the beam includes a neutral position and a deflected position, a pull wire coupled to the distal end of the beam, wherein the beam is configured to be placed in the deflected position when a tension force is applied to the pull wire, and wherein at least a portion of the pull wire is configured to move to a displacement distance away from the beam when the tension force is applied to the pull wire, and one or more constraint members operatively coupled to the beam, wherein each one of the one or more constraint members is configured to limit the displacement distance of the pull wire from the beam when the tension force is applied to the pull wire.

An air gap retractor illumination system includes any suitable retractor such as a McCulloch with a channel in the blade to accommodate an air gap illuminator. The illuminator is preferably made from a suitable light conducting plastic material such as acrylic or polycarbonate or silicone. The illuminator has active portions in which light passes and inactive or dead zones in which light does not pass as a result of the configuration and orientation of the input, output and surfaces of the illuminator. The illuminator is formed to have an air gap surrounding any active portion of the illuminator extending from the light input to the light output portion. The dead zones may include elements to allow the illuminator to securely engage the retractor. The light output portion of the illuminator contains from two to eight output zones, each zone having specially designed output optical structures that control and direct light to escape the illuminator to shine onto a predetermined area of interest or to form one or more predetermined shapes or footprints.

A surgical retractor for illuminating a surgical field includes an ergonomic handle, a retractor blade coupled with the handle, a quick release mechanism, and an illuminator blade. The retractor blade is adapted to engage and retract tissue, and the quick release mechanism is adapted to couple the handle with the retractor blade. The illuminator blade acts as a waveguide to transmit light by total internal reflection. Light is extracted from the illuminator to illuminate the surgical field. The retractor blade is releasable from the handle without requiring uncoupling of the illuminator blade from the handle and also without requiring optical uncoupling of the illuminator blade from a light source. The retractor may also be adapted to evacuate smoke from the surgical field.

A portable dual-blade retractor comprising a handle having a first end and a second end, a first blade extending from the first end of the handle, a second blade extending from the second end of the handle, and an illumination assembly including (a) one or more first direct light sources provided on the first blade and (b) one or more second direct light sources provided on the second blade, wherein the first and second direct light sources are individually controlled.
