Embodiment Construction

[0057] 1 is a side view of an exemplary embodiment of a flexible endoscopic instrument, generally indicated at 10, shown with user controls 18 in a second position and end effector 14 in a closed mechanism. Instrument 10 includes an elongated flexible shaft 16 having a proximal end 20 and a distal end 22 . A physician may insert the flexible portion of instrument 10 into a lumen, such as the working channel of an endoscope or the natural opening of a patient. The instrument 10 may also include a handle 12 connected to the proximal end 20 of the shaft 16 . A user may grip handle 17 of handle 12 while actuating user controls 18 to operate end effector 14 . The configuration of the handle 12 shown in FIG. 1 is only one example of many possible configurations.

[0058] 2 is a detailed cross-sectional view of end effector 14 of instrument 10, shown in an open configuration. FIG. 3 is a detailed view of end effector 14 shown in a closed configuration. The end effector 14 include...

Abstract

A medical instrument includes a shaft having a channel extending therethrough and an actuating element extending through the channel. The instrument further includes an end effector disposed on the distal end of the shaft and operatively connected to the distal end of the actuating element, wherein the actuating element is adapted to move the end effector between a first configuration and a second configuration. The instrument further includes a control moveable between a first position corresponding to the first configuration, and a second position corresponding to the second configuration, wherein the control is operatively disconnected from the actuating element when the control is in the first position.

Description

technical field [0001] The present invention relates to medical instruments and, more particularly, to surgical endoscopic instruments. Background technique [0002] Physicians use long, flexible instruments inserted through flexible endoscopes to perform certain medical procedures through natural openings in a patient's body, sometimes avoiding more costly and painful surgical procedures. The flexible endoscopic instrument may have a shaft portion with a length of about 1 to 2 meters and a diameter of about 1 to 2 millimeters. The shaft may comprise a flexible tube having a channel and an actuating element, such as a wire, extending through the channel. A control device may be operably connected to the proximal end of the actuation element for operating the end effector at the distal end of the shaft. [0003] Sometimes inadvertently, relative motion between the actuation element and the tube may result in uninitiated action of the end effector. This may occur, for examp...
