    摘要： A surgical implement, such as a surgical electrode, and an ultrasound transducer, both extend through a single elongated insertion member, typically, a catheter. The ultrasound transducer extends from the proximal region of the surgical instrument containing the instrument controls toward the distal end of the catheter from which at least the operative tip of the surgical implement and the ultrasound transducer extend. In one embodiment, the catheter also contains a fiber-optic endoscope, thus allowing visual as well as ultrasound monitoring of the surgical site, before, during and after conduct of the surgical procedures. Means are provided for rotation of the ultrasound transducer to enable generation of a circular tissue reflectivity image transverse to the axis of the ultrasound transducer. Means are also provided for selective longitudinal movement of all elements contained within the catheter. Liquid crystal or other display means are provided to facilitate visual monitoring of the ultrasound and if present the endoscope outputs in real time. In embodiments including an endoscope, an optical eyepiece is provided to facilitate monitoring of its output. An ultrasound medium within the surgical site is provided by fluid inlet and removal means through the catheter.

    摘要： An electrosurgical selectively controllable loop electrode for laparoscopic surgery is set forth which includes a housing having a longitudinal axis and an axially extending cavity forming a passageway through the housing. A shaft member is slideably mounted to the housing within the cavity so as to permit axial and rotational displacement of the shaft member relative to the housing. A wire electrode which has a first end segment and a second end segment is in electrical communication with the shaft member and extends distally therefrom; the wire electrode also has a bridge segment integrally interconnecting the first and second end segments to form a loop. The end segments are biased by a pair of leaf springs of predetermined curvature where the springs are internally biased to open upon extension of the springs distally from the housing and to close upon external forces exerted against the springs by the housing during retraction. In another embodiment of the invention, the first and second end segments have a predetermined equilibirum shape and are self-biased to return to the equilibirum shape when displaced therefrom; the bridge segment integrally interconnecting the first and second end segments to form a loop is responsive to the internal restoring forces created when the bridge segment is displaced from equilibirum and the bridge segment articulates radially with respect to the end segments through a sequence of predetermined shapes.
