摘要： Surgical devices and methods for utilizing optical coherence tomography (OCT) to monitor and control tissue sealing are disclosed. The surgical device includes an end effector assembly that includes first and second jaw members that are movable between a first, spaced-apart position and a second proximate position. An OCT system, at least a portion of which is incorporated into the end effector assembly, is configured to sense properties of the tissue, e.g., the structural density of the tissue, disposed between the first and second jaw members. A tissue-sealing energy source may be disposed within at least one of the jaw members and may provide tissue-sealing energy to tissue disposed between the jaw members. A controller, which is coupled to the OCT system and the tissue-sealing energy source, controls the tissue-sealing energy generated by the tissue-sealing energy source based on the properties of the tissue sensed by the OCT system.

摘要： An ultrasonic surgical instrument (10) includes a transducer assembly having a distal engagement member (266) and configured to supply ultrasonic energy. A waveguide (30) defines a longitudinal axis and has a proximal engagement member (34) configured to threadingly engage the distal engagement member. The waveguide is configured to transmit the ultrasonic energy therealong to a distal end thereof for treating tissue. A torque member (300) is coupled to the transducer assembly and is disposed about the longitudinal axis. The torque member is selectively rotatable about the longitudinal axis and relative to the waveguide to threadingly engage the transducer assembly and the waveguide to one another. The torque member includes a plurality of fingers (322) pivotably coupled thereto and movable between a closed position and an open position. In the open position, each finger extends substantially perpendicularly from the longitudinal axis to define a moment arm that facilitates the engagement of the transducer assembly and the waveguide.

摘要： A medical instrument includes two jaw members, each of which creates conditions of frustrated total internal reflection at a tissue-contacting surface when tissue is grasped between the two jaw members. The first jaw member may include an optical element having a tissue-contacting surface. The medical instrument also includes plural light sources that provide light beams for sealing tissue. The light source is positioned so that the light beam is totally internally reflected from an interface between the tissue-contacting surface and air when tissue is not grasped by the jaw members. When tissue is grasped by the jaw members, at least a portion of the light beam is transmitted through that portion of the tissue-contacting surface that is in contact with the tissue. The light source may be movably coupled to a jaw member to scan the light beam and/or to change the incident angle based on optical properties of the tissue.
