Abstract: A surgical instrument is disclosed herein. The surgical instrument can include an end effector that includes jaws configured to transition between an opened condition and a closed condition, a plurality of electrodes positioned within the jaws of the end effector, a control circuit, and a memory configured to store an algorithm configured to cause the control circuit to determine an impedance signal based on signals received from the plurality of electrodes, detect a media positioned between the jaws of the end effector based on the determined impedance signal, determine a position of the detected media based on the received signals, and generate an alert associated with the detected media and the determined position.

Abstract: A computer-implemented method for controlling an endoscope having a flexible tubular body, the method comprising: deploying an anchor to stabilise at least a part of the flexible tubular body; and performing active image stabilisation to stabilise the position of a camera at a distal end of the endoscope.

Abstract: A method of assembling an adjustable fluid-filled lens assembly comprising biaxially tensioning an elastomeric membrane to a surface tension of greater than 180 N/m, typically greater than 1000 N/m; thermally conditioning the tensioned membrane, e.g., for one hour at a temperature of about 80° C., to accelerate relaxation of the membrane; mounting the membrane to a peripheral support structure whilst maintaining the tension in the membrane; assembling the mounted membrane with one or more other components to form an enclosure with the membrane forming one wall of the enclosure; and thereafter filling the enclosure with a fluid. The membrane may be formed from an aromatic polyurethane, and the fluid may be a phenylated siloxane. In some embodiments, the membrane is able to hold a substantially constant surface tension of at least 180 N/m for a period of at least 12 months.

Abstract: A method and system are disclosed for recognizing tissue types. Electrical signals are applied to tissue 120 via electrodes 110, 112. Circuitry 106 and the signal processor 116 are used to measure impedance magnitude and phase at a plurality of frequencies. At least the phase information at the plurality of frequencies is compared with phase information of known tissue types. Based on the comparison, the tissue 120 may be assigned to one of the known tissue types.
