A method for constructing a modular surgical system is disclosed. The method comprises providing a header module comprising a first power backplane segment, providing a surgical module comprising a second power backplane segment, assembling the header module and the surgical module to electrically couple the first power backplane segment and the second power backplane segment to each other to form a power backplane, and applying power to the surgical module through the power backplane.

Embodiments of the present disclosure provide an apparatus and method for reducing surgical smoke. An exemplary apparatus includes trocar comprising a tubular hollow body circumscribing a cavity extending through a longitudinal axis of the trocar with a gasket at a first end and an exit port at a second end, the tubular hollow body comprising a first wall circumscribing the cavity and a concentrically spaced apart second wall. The apparatus further includes a first plate operable to maintain an electric charged disposed within the cavity on the first wall, and a second plate operable to maintain an electric charge disposed between the first wall and the spaced apart second wall.

A medical apparatus includes a treatment device configured to be capable of treating a subject by applying energy to the subject, an optical fiber including a light emitting face for emitting light into the subject, the optical fiber being connected to the treatment device, and a shield portion that is disposed in front of the light emitting face of the optical fiber, the shield portion being configured to expose the light emitting face when the treatment device does not perform a treatment operation and to shield the light emitting face when the treatment device performs the treatment operation.

An ophthalmic speculum includes arms, a locking mechanism, and an air-flow system. The arms include a first arm and a second arm. Each arm has a retractor shaped to conform to an eyelid of a pair of eyelids of an eye. The retractors are substantially symmetrical about a lateral axis. The locking mechanism is coupled to the arms. The locking mechanism moves the arms to allow the retractors to retract the pair of eyelids, and fixes the arms into place to maintain retraction of the pair of eyelids. The air-flow system is coupled to at least one arm, and moves air in a region disposed outwardly from a surface of the eye.

A portable electrosurgical device (ESD) has a housing, a probe connected to the housing and a heating element connected to the probe for destroying human tissue. The heating element is detachable from the probe and/or the probe with heating element can be detachable from the housing. The user can set a drive signal's electrical characteristics, such as operating frequency, duty cycle, peak voltage and the like for a customized drive signal formed in the ESD based on the heating element used. Memory storage allows for storage of inputted data from a keyboard, downloaded reference documents and information off the Internet from an Ethernet connector that can be displayed for reference on a screen of the ESD. Another even more compact ESD is an integral one-piece portable device having a type of pistol hand-held grip, dis-connectable probe, and a rechargeable, removable battery in the handle provides approximately 30, one-minute treatments on a single battery charge.

An insertion instrument includes a shaft projecting, by being inserted through a hole of a fixing instrument, from a distal end of the fixing instrument toward a distal side, and a gas supply channel formed in the shaft section and having a jet port, which jets a gas, in a distal portion of the shaft section. The gas is supplied from a proximal side to the distal side toward the jet port in the gas supply channel, and an extension dimension along the longitudinal axis from the jet port toward the proximal side is greater than an extension dimension of the hole of the fixing instrument.

A surgical-data-processing modification command may be triggered based on changing surgical data processing requirements of the surgical procedure. And the surgical-data-processing modification command may direct changes in processing such as output frequency, output resolution, processing resource utilization, operational data transforms, and the like. The surgical-data-processing modification command and the system disclosed herein may be used to implement a variety of processing strategies for surgical sensing, including procedure specific load balancing and sensor prioritization.

A device to output data associated a surgery may include a processor that may be configured to receive, before the surgery, first patient data. The processor may be configured to generate a transform before the surgery. The processor may be configured to receive second patient data during the surgery and to apply the transform based on the received second patient data satisfying a condition of the transform. The transform may be applied to the second patient data to derive third patient data. The third patient data may include the second information and contextual information about the second information. For example, the third patient data may include an alert to a health care professional with a present value of a biomarker and an indication of the magnitude and/or nature of the present value's deviation from a baseline.

Insufflation systems may provide a continuous flow of insufflation gas to a body cavity. The continuous flow may be directed over the lens of an endoscope received within a cannula to form a protective envelope around the lens and improve visibility. The continuous flow may be supplied by a pressurized gas source. The continuous flow line may be assembled in parallel to an insufflation line running through a standard insufflator configured to provide non-continuous gas flow to the body cavity. The lines may converge upstream of or at the cannula or the insufflation flow may be provided to a separate cannula. Continuous gas flow may be provided by recirculating gas from the body cavity through the cannula Continuous gas flow may be provided by storing gas from the non-continuous insufflation flow in an accumulator and releasing the gas during off phases of the insufflation flow.

Various surgical hubs are disclosed. A surgical hub comprises a storage device; a processor coupled to the storage device; and a memory coupled to the processor. The memory stores instructions executable by the processor to: receive data from a surgical instrument coupled to the surgical hub; and determine a rate at which to transfer the data from the surgical hub to a remote cloud-based medical analytics network based on available storage capacity of the storage device.
