Endoscope with guide
First Claim
1. An instrument for use with an endoscope, the instrument comprising:
- an elongate section configured to move exterior to the endoscope, the elongate section including a distal end and a proximal end;
an end effector attached to the distal end of the elongate section;
an actuation device attached to the proximal end of the elongate section, the actuation device being configured to operate the end effector; and
a guiding member integral with and immovable relative to the elongate section, the guiding member being configured to slidably encircle an external surface of the endoscope to permit the guiding member to move along a longitudinal axis of the endoscope, the guiding member being integral with 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;
wherein the guiding member is configured to interface with a feature on the external surface of the endoscope to stop the movement of the guiding member along the longitudinal axis of the endoscope.

Abstract
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.

16. A method of using an endoscopic instrument at a work site internal to a body, the method comprising:
-
inserting a distal end of an endoscope into the body; locating the distal end of the endoscope proximate to the worksite; coupling an endoscopic instrument to the endoscope, the endoscopic instrument having an elongate section, an end effector attached to a distal end of the elongate section, an actuation device attached to a proximal end of the elongate section to operate the end effector, and a guiding member integral with and immovable relative to the elongate section between the end effector and the actuation device, the guiding member encircling an external surface of the endoscope and slidably coupling the endoscopic instrument to an external surface of the endoscope; moving the endoscopic instrument along a longitudinal axis of the endoscope so that the end effector extends a first distance away from the distal end of the endoscope; and operating the endoscopic instrument at the worksite, wherein the operating includes moving the distal end of the elongate section and the end effector in a transverse direction independent of movement of the distal end of the endoscope; wherein the external surface of the endoscope includes a feature to stop movement of the guiding member past a maximum distance greater than or equal to the first distance. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A medical device comprising:
-
an endoscope with a proximal end, a distal end, and an elongate section connecting the proximal and distal ends; an endoscopic instrument with an end effector at a distal end, an actuation device at a proximal end, and a shaft coupling the end effector to the actuation device, the endoscopic instrument extending completely external to the endoscope; and one or more guiding members integral with and immovably coupled to the shaft and slidably encircling an external surface of the elongate section to permit the end effector to move along a longitudinal axis of the endoscope, the one or more guiding members being coupled to the shaft such that the end effector may extend past the distal end of the endoscope and move in a transverse direction independent of the movement of the distal end of the endoscope; and a stop configured to limit the extension of the end effector past the distal end of the endoscope. - View Dependent Claims (32, 33, 34, 35)
