Abstract: Methods for treating tissue, and surgical assemblies and related methods are disclosed in which a single input is used to sequentially articulate two members. A surgical assembly includes an end effector, a base supporting the end effector, an input link movable relative to the base through a range of motion between a first configuration and a second configuration, and an actuation mechanism. The end effector includes a first articulated member and a second articulated member. The actuation mechanism drivingly couples the input link to the first articulated member within a first portion of the range of motion and drivingly coupling the input link with the second articulated member within a second portion of the range of motion so that a movement of the input link from the first configuration to the second configuration articulates the first articulated member and then articulates the second articulated member.

Abstract: Embodiments of the technology provide an articulable electrosurgical instrument and methods of performing electrosurgery with an articulating capability. The electrosurgical instrument includes an elongated shaft having an end effector associated with a distal end thereof that is able to deliver energy to a target tissue site. An articulable joint is positioned between that shaft and the end effector. Articulation of the articulable joint is controlled by a stabilizable articulation actuator, which may include a rotatably stabilizable disk residing within a well. The end effector may take the form of forceps including an upper and a lower jaw; the jaws are configured to grasp target tissue and to deliver energy, such as radiofrequency energy. In some of these instruments, the end effector is adapted to seal tissue by the application of radiofrequency energy, and then to cut through the sealed tissue portion.

Abstract: A surgical instrument can include a shaft having a proximal end and a distal end, and a wrist coupled to the distal end of the shaft and configured to articulate in multiple degrees of freedom coupled to the distal end of the shaft. The surgical instrument can further include an end effector supported by the wrist, wherein the end effector includes a cutting element and jaws configured to grip tissue and fuse tissue via electrosurgical energy. The surgical instrument can be configured for use with a teleoperated robotic surgical system that can include a patient side console configured to interface to actuate the surgical instrument and a surgeon side console configured to receive inputs from a surgeon to control the actuation of the surgical instrument.

Abstract: Embodiments of the invention provide methods for inserting a non-metallic multi-strand braid through a coil tube. Techniques for bonding one end of a lead line to one end of a multi-strand non-metallic braid are provided. There are also embodiments of steerable instruments described having a plurality of hinged segments; a multi-strand non-metallic braid connected distally to one segment of the plurality of segments and proximally to an actuator; and a steering controller adapted to control the actuator to move the hinged segment using the multi-strand non-metallic braid.

Abstract: A medical instrument has a set of opposing jaws that can be articulated, both left and right, from centerline. The instrument has a proper bend radius and support for the jaw actuation member and cutter driving member. The bendable support for the drive members comprises tightly wound coil springs. Another embodiment of the invention controls the degree of articulation at the handle of the laparoscopic instrument. A further embodiment of the invention incorporates a locking mechanism to prevent motion of the wrist while the user performs other operations on the device. The locking mechanism also includes an indexing feature with which the user can index and choose the necessary amount of angle between preset angles.

Abstract: The present invention relates, generally, to the reduction or elimination of permanent and catastrophic herniations in Bowden cables or coil pipes in articulating devices or snake-like robots. More particularly, the present invention relates managing the coil pipes in a spiral pattern along the articulating device or snake-like robot to reduce or eliminate the necessity of the Bowden cables or coil pipes to slide along the length of the articulating device or snake-like robot. Reduction or elimination of the necessity for the Bowden cables or coil pipes to slide reduces or eliminates catastrophic herniations in articulating devices or snake-like robots undergoing one or more articulations.
