An electrosurgical smoke evacuation pencil includes a handle housing, a suction conduit, an electrode, and a nozzle. The handle housing has a proximal end portion and a distal end portion and defines a lumen therethrough. The suction conduit is coupled to the handle housing and is configured to couple the electrosurgical pencil to a smoke evacuator. The electrode extends from the distal end portion of the handle housing and is configured to couple to a source of electrosurgical energy. The nozzle extends from the distal end portion of the handle housing and defines a lumen in fluid communication with the lumen of the handle housing. The nozzle is configured to transmit light from a light source through the nozzle and out of a distal end of the nozzle to form a light path illuminating therefrom.

Certain aspects relate to systems and techniques for optical strain sensing in medical instruments. In one aspect, a medical instrument includes an elongated shaft, and at least one pull wire extending from a proximal end of the elongated shaft to the distal end of the elongated shaft. The at least one pull wire is configured to cause actuation of the medical instrument in at least one degree of freedom. The at least one pull wire includes an optical fiber configured to provide an indication of strain along the at least one pull wire.

An instrument to facilitate hands-free illumination of an eye for a surgical procedure. The instrument includes an optical end of unique architecture and surfacing such that the instrument may be left immobile while sufficiently illuminating an eye interior with greater than 100° of wide beam spread angle provided. Further, the grind surfacing provided to the end cone of the optical end provides enhanced light distribution.

Surgical apparatus for performing a microsurgery including a cannula having an intraocular portion. The intraocular portion connects to an infusion tube. The intraocular portion includes fenestrations at its distal end. The intraocular portion receives fluid through the infusion tube and dispenses the fluid through the fenestrations lessening the flow at an infusion site in an eye. The surgical apparatus includes a vitreous cutter. The vitreous cutter includes a suction tube at one end and a shaft at another end. The cutting port cuts vitreous into smaller pieces or a laser that liquefies the vitreous. The shaft receives the cut vitreous pieces and the suction tube draws out the cut vitreous pieces from the eye. The surgical apparatus includes a vitreoretinal surgical tool having a vitreoretinal cutter. The vitreoretinal cutter has a scissor-like or forceps-like mechanism. The vitreoretinal cutter holds and/or cuts a membrane in the eye during the microsurgery.

A system controller can predict, when a first operation is performed on one device of a plurality of devices including a medical instrument, a subsequent operation that is the operation that occurs most frequently after the first operation based on an operation history information table in which past operation information is recorded for each procedure performed on the plurality of devices. This information can be displayed on an operation screen of an operation panel apparatus.

Systems and methods for image detection during grasping and stapling include an end effector having a first jaw and a second jaw, an imaging sensor mounted to the end effector and configured to capture images of a material graspable by the end effector, and one or more processors coupled to the end effector and the imaging sensor. The one or more processors are configured to receive the images from the imaging sensor, determine one or more properties of the material based on the images, and display the one or more properties of the material on an interface. In some embodiments, the end effector is part of a medical tool and the material is anatomical tissue. In some embodiments, the end effector further includes one or more of a stapling mechanism configured to staple the material or a cutting mechanism configured to cut the material.

A medical observation control device and system include a memory that stores a parameter for a first imaging condition of an imager at a first time of capturing a first medical image and circuitry configured to correct for brightness differences between the first medical image captured at the first time and a second medical image captured at a second time. The circuitry is configured to restore the parameter for the first imaging condition as a second imaging condition for capturing the second medical image, control the imager so as to capture an image of an observation object under the second imaging condition as the second medical image, compare the first medical image with the second medical image, and correct brightness of at least one of brightness of the first medical image and brightness of the second medical image based on a comparison result.

An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.

A system for use in surgery includes a central body, a visualization system operably connected to the central body, a video rendering system, a head-mounted display for displaying images from the video rendering system, a sensor system, and a robotic device operably connected to the central body. The visualization system includes at least one camera and a pan system and/or a tilt system. The sensor system tracks the position and/or orientation in space of the head-mounted display relative to a reference point. The pan system and/or the tilt system are configured to adjust the field of view of the camera in response to information from the sensor system about changes in at least one of position and orientation in space of the head-mounted display relative to the reference point.

Method and apparatus for treating peripheral olfactory dysfunction are described herein. One method may include introducing a treatment device into a nasal cavity of the patient, the treatment device having a proximal end, a distal end, an elongated shaft therebetween, and a treatment end effector disposed on or near the distal end. The distal end of the treatment device may be advanced into proximity of a cribriform plate within the nasal cavity and at least one olfactory neuron may be ablated through the cribriform plate via the treatment end effector to reduce at least one symptom of olfactory dysfunction.
