    摘要： Ablation systems and methods detect and address distortion caused by a variety of factors. A method includes measuring a temperature curve at target tissue; applying ablation energy to the target tissue; determining a peak temperature on the temperature curve; if the peak temperature is greater than the predetermined peak temperature, determining a time at which the temperature curve crosses to a lower temperature; and if the determined time is greater than a predetermined time, generating a message indicating that the target tissue was successfully ablated. Another method includes determining a distance between a remote temperature probe and an ablation probe, applying ablation energy to target tissue, measuring temperature at the remote temperature probe, estimating ablation size based on the determined distance and the temperature measured by the remote temperature probe, and determining whether the target tissue is successfully ablated based on the estimated ablation size.

    摘要： An ultrasonic surgical instrument includes a transducer assembly having a distal engagement member and configured to supply ultrasonic energy. A waveguide defines a longitudinal axis and has a proximal engagement member 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 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 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： An endoscopic instrument is provided and includes a housing including an elongated shaft assembly extending distally therefrom. The elongated shaft assembly includes inner and outer shaft members. The inner and outer shaft members are removably coupled to the housing and the outer shaft member is movable with respect to the inner shaft member. An end effector is operably supported at the distal end of the outer shaft member and includes a pair of jaw members configured for treating tissue. A bushing operably couples to the inner and outer shaft members of the shaft assembly and selectively and releasably couples to the housing. The bushing includes one or more mechanical interfaces configured to engage one or more slots defined through the inner shaft member and one or more slots defined through the outer shaft member to release the inner and outer shaft members from the housing.

    摘要： A system for performing a surgical procedure includes a camera configured to capture real-time near infrared images, an injection system configured to inject a fluorescent dye into a patient's blood stream, and a workstation operably coupled to the camera for retrieving a three-dimensional (3D) model of the patient's anatomy based on pre-procedure images, retrieve an indication of a targeted critical structure within the 3D model, observe, using the captured real-time near infrared images, perfusion of the fluorescent dye through tissue to identify critical structures illuminated by near-infrared light, and register the real-time near-infrared images to the 3D model using the identified illuminated targeted critical structure in the real-time near infrared images captured by the camera and the identified targeted critical structure in the 3D model as a landmark.

    摘要： A forceps includes a handle, a shaft having a proximal end coupled to the handle, and an end effector assembly coupled to a distal end of the shaft. The forceps includes a first jaw member and a second jaw member for grasping tissue therebetween. One or both of the first and second jaw members may include one or more needles extending therefrom. The one or more needles are in fluid communication with a fluid conduit extending along one or both of the first and second jaw members. The fluid conduit couples to a source of contrast agent to enable selective delivery of the contrast agent through the one or more needles.
