A flexible approach to segmenting a resource (e.g., a media resource, such as a media segment, or other resource, such as a resource normally fetched or pushed using general file transfer protocols like HTTP) into a plurality of fragments. By employing such an approach, the delay until the resource can be utilized at the client side is reduced. Certain embodiments are provided which apply the flexible segmentation approach to ISOBMFF media segments for video streaming, such as would be used with Live DASH streaming.

The present disclosure is directed to a robotic surgical system and a corresponding method. The system includes at least one robot arm and a radiation source coupled to the robot arm. The system also includes a surgical table having a digital imaging receiver configured to output an electrical signal based on radiation received from the radiation source. A controller having a processor and a memory is configured to receive the electrical signal and generate an initial image of a patient on the surgical table based on the electrical signal. The controller transforms the initial image to a transformed image based on an orientation of the radiation source.

Prosthetic capsular devices (e.g., bag, bowl, housing, structure, cage, frame) include technology devices such as a computer, virtual reality device, display device, WiFi/internet access device, image receiving device, biometric sensor device, game device, image viewers or senders, GPSs, e-mail devices, combinations thereof, and/or the like. The technology devices can be used in combination with an intraocular lens. The output from the technology device(s) can be fed to the retina of the user to provide a visual image, can be otherwise connected to the user, and/or can be used to control the properties of the intraocular lens or of the prosthetic capsular device. Wearable technology that provides biometric data, such as blood glucose levels, body temperature, electrolyte balance, heart rate, EKG, EEG, intraocular pressure, sensing ciliary muscle contraction for accommodation stimulus, dynamic pupil change and retinal prostheses, combinations thereof, and the like can assist in technology-assisted health care functions.

A stopper according to one or more embodiments may include: a stopper body; and a rotation restriction portion provided at the stopper body and configured to restrict rotations of the drive transmission member. The stopper may be configured such that the rotation restriction portion restricts the rotations of the drive transmission member in a state where the stopper body is attached to the adaptor main body and the rotation restriction portion releases the restriction of the rotations of the drive transmission member in a state where the stopper body is detached from the adaptor main body.

An instrument system comprising a flexible shaft having proximal and distal portions, a backend mechanism coupled to the proximal portion, and a plurality of tendons including first and second tendons. The backend mechanism comprises a plurality of capstans including first and second capstans. Each capstan includes a bore for engagement with a drive shaft, and a capstan coupling member adapted to engage a drive shaft coupling member such that rotation of the drive shaft causes rotation of the capstan, and adapted to disengage from the drive shaft coupling member so rotation of the drive shaft does not cause rotation of the capstan. The first tendon is configured to wrap around the first capstan and the second tendon is configured to wrap around the second capstan. The first and second tendons are coupled to a member disposed at the distal portion and are configured to move the member in opposing directions.

Navigation assistance systems and methods for use with a surgical instrument to assist in navigation of a surgical instrument during an operation. The system may include sensors that may observe the patient to generate positioning data regarding the relative position of the surgical instrument and the patient. The system may retrieve imaging data regarding the patient and correlate the imaging data to the positioning data. In turn, the position of the surgical instrument relative to the imaging data may be provided and used to generate navigation date (e.g., position, orientation, trajectory, or the like) regarding the surgical instrument.

The subject disclosure is directed to an articulated medical device having a sensor for detecting outside movements applied upon the medical device while in a subject or patient, wherein the device is capable of maneuvering within the subject or patient while taking the outsides movements into consideration.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

For control about a remote center of motion (RCM) of a surgical robotic system, possible configurations of a robotic manipulator are searched to find the configuration providing a greatest overlap of the workspace of the surgical instrument with the target anatomy. The force at the RCM may be measured, such as with one or more sensors on the cannula or in an adaptor connecting the robotic manipulator to the cannula. The measured force is used to determine a change in the RCM to minimize the force exerted on the patient at the RCM. Given this change, the configuration of the robotic manipulator may be dynamically updated. Various aspects of this RCM control may be used alone or in combination, such as to optimize the alignment of workspace to the target anatomy, to minimize force at the RCM, and/or to dynamically control the robotic manipulator configuration based on workspace alignment and force measurement.

A force sensor apparatus is provided including a tube portion having a plurality of radial ribs and at least one fiber optic strain gauge positioned over each rib of the plurality of radial ribs. A proximal end of the tube portion is operably couplable to a shaft of a surgical instrument that is operably couplable to a manipulator arm of a robotic surgical system, and a distal end of the tube portion is proximally couplable to a wrist joint coupled to an end effector. A thermal shunt shell is over an outer surface of the tube portion.
