    摘要： An instrument for use with an endoscope may include an elongate section configured to move exterior to the endoscope. The elongate section may include a distal end and a proximal end. The instrument may also include an end effector attached to the distal end of the elongate section, and an actuation device attached to the proximal end of the elongate section. The actuation device may be configured to operate the end effector. The instrument may also include a guiding member coupled to the elongate section. The guiding member may be configured to be coupled to an external surface of the endoscope to permit the guiding member to move longitudinally relative to the endoscope. The guiding member may be coupled to the elongate section such that the end effector may extend past a distal end of the endoscope and move in a transverse direction independent of the movement of the distal end of the endoscope.

    摘要： This invention is directed to a flexible device having a longitudinal axis, a first elongate member configured to move the flexible device in a first direction relative to the longitudinal axis, and a second elongate member configured to move the flexible device in a second direction relative to the longitudinal axis that is different to the first direction. The flexible device can also have an articulation section including a plurality of articulation links, wherein at least one of the plurality of articulation links can include a body configured to receive the first elongate member and the second elongate member. The flexible device can also include a cinching element configured to engage the first elongate member to substantially limit movement between the plurality of articulation links when a tensile force is applied to the first elongate member and configured to disengage the first elongate member to permit movement between the plurality of articulation links when a tensile force is applied to the second elongate member.

    摘要： Described herein are various systems and methods for directing endoscopy instruments to varying positions at a target site. In one aspect, at least one instrument channel has multiple exit points at the distal end of the guide tube, and the position of an instrument delivered through the channel may be switched between the different exit points. In another aspect, an instrument channel splits into multiple branches at the distal end of the guide tube, and the position of an instrument at the target site may be changed by selectively directing the instrument into a different channel branch. In yet another aspect, the guide tube, or a portion thereof, may be rotated to reposition an instrument at the target site. The capability of changing the instrument positions during a procedure would enable a physician to examine or treat multiple target sites within an operative field, without necessitating the full retraction of the instruments or the guide tube from the operative field.

    摘要： A system for performing a medical operation includes an end effector having first and second arms, each extending from a distal end to a proximal end, the proximal ends being connected to one another, the end effector being movable between a closed configuration wherein the first and second arms are separated from one another by a first distance and an open configuration wherein the first and second arms are separated from one another by a second distance greater than the first distance, a distance between the first and second arms being substantially constant from the proximal ends to the distal ends, wherein the end effector is biased to the open configuration. A first plate element extends from a first surface configured to engage a first wall of the first arm to a second surface configured to contact target tissue in an operative configuration. A second plate element extends from a first surface configured to engage a first wall of the second jaw to a second surface configured to contact target tissue in an operative configuration.
