摘要:
A system for operating within an interior region of the eye, or other organ, includes a delivery channel having a proximal portion located exterior to the eye and a distal portion positionable within the interior region of the eye, wherein the distal portion of the delivery channel defines an outer diameter that is smaller than or equal to about 18 gauge, and a micro-robot extendable from the distal portion of the delivery channel, wherein the micro-robot is remotely operable to change shape within the interior region of the eye.

A sensing system for implant surgery includes an insertion device for moving an implant into a narrow cavity in a patient's body. A sensor measures the distance from an end of the insertion device to anatomic surfaces at a distance from the end of the insertion device. An optical coherence tomography (OCT) system integrates the sensor and produces OCT images, which can be quantified to distance measurements. The system is particularly useful for cochlear implant surgery.

A system for cochlear implant surgery includes a reference device having at least a portion adapted to be arranged at a fixed position relative to a cochlea of a patient to provide a reference position, an image acquisition and processing system adapted to acquire an image of at least a portion of the cochlea relative to the reference position and to provide an implant plan based at least partially on the acquired image, and an implant system adapted for implanting a cochlear lead array using the reference position and the implant plan.

A method for guiding a surgical cannula having a plurality of overlapping flexible tubes includes determining a desired cannula path; selecting the plurality of flexible tubes, wherein each of the flexible tubes within the plurality has a pre-formed curvature and a flexibility; determining a final overlap configuration of the plurality of flexible tubes such that a resulting curvature of the overlap configuration substantially corresponds to the desired cannula path; and determining a plurality of intermediate overlap configurations of the plurality of flexible tubes. Each of the intermediate configurations correspond to the desired cannula path.

A system and method for cooperative control of surgical tool includes a tool holder for receiving a surgical tool adapted to be held by a robot and a surgeon, a sensor for detecting a force based on operator input and/or tool tip forces, a controller for limiting robot velocity based upon the force detected so as to provide a haptic feedback, a selector for automatically selecting one level of a multi-level audio feedback based upon the detected force applied, the audio feedback representing the relative intensity of the force applied, and an audio device for providing the audio feedback together with the haptic feedback. The audio feedback provides additional information to the surgeon that allows lower forces to be applied during the operation.
摘要:
A tracking and navigation system is provided. The system includes an imaging or treatment device, a tracker device, and a fiducial marker. At least part of the imaging or treatment device is movable relative to a patient. The tracker device is mounted on the imaging or treatment device and is movable therewith relative to the patient. The fiducial marker may be fixed relative to the patient to define a patient coordinate system. The fiducial marker is detectable by the tracker device to substantially maintain registration between the tracker device and the patient coordinate system. A tracking and navigation kit including the tracker device and at least one fiducial marker may also be provided, for example, for retrofitting to existing imaging or treatment devices
摘要:
A method and system for micro-force guided cooperative control that assists the operator in manipulating tissue in the direction of least resistance. A tool holder receives a surgical tool adapted to be held by a robot and a surgeon. A first sensor measures interaction forces between a tip of the surgical tool and tissue of a region of interest. A second sensor measures interaction forces between the surgeon and a handle to the surgical tool. A data processor is configured to perform an algorithm to actively guide the surgical tool by creating a bias towards a path of least resistance and limit directional tool forces of the surgical tool as a function of handle input forces and tip forces. This function offers assistance to challenging retinal membrane peeling procedures that require a surgeon to delicately delaminate fragile tissue that is susceptible to hemorrhage and tearing due to undesirable forces.

A motion-compensating surgical tool system includes a surgical tool that includes a hand piece and a moveable component, a drive assembly connecting the moveable component to the hand piece such that the moveable component is movable in an axial direction relative to the hand piece by the drive assembly. The motion-compensating surgical tool system also includes an optical detection system that includes an optical fiber attached to the moveable component with an end at a fixed distance to a distal-most portion of the moveable component. The optical detection system is configured to output a signal for the determination of a distance of the distal-most portion of the moveable component to a target during surgery.
摘要:
Featured are systems, devices and apparatuses for use in minimally invasive surgical, diagnostic or therapeutic methods and/or techniques, in particular methods and/or techniques for a mammalian throat. In particular embodiments, a dexterity apparatus including one or more dexterity devices is featured, where each of the dexterity devices comprises surgical tools and each is configured and arranged with end-tip dexterity for enhanced manipulation. A portion of the dexterity devices is snake like, which is re-configurable (i.e., can be bent) so as to in effect maneuver the surgical tool and put the tool in a desired position with respect to the surgical site. Another portion of the dexterity device includes the surgical tool thereby providing the capability of performing surgical actions such as sewing, gripping, soft tissue manipulation, cutting and suction of saliva, blood and other materials from the surgical site.
