Abstract:
An endoscopic instrument comprising:a tubular member having a proximal end, a distal end, and a lumen extending therethrough; a handle coupled to the proximal end of the tubular member, the handle having an actuating mechanism; a drive rod disposed within the lumen of the tubular member, the drive rod having a proximal end and a distal end, the proximal end of the drive rod being coupled to the actuating mechanism of the handle such that the drive rod moves axially within the lumen in response to a change in force applied to the actuating mechanism; at least one boss protruding radially from a portion of the drive rod near the distal end of the drive rod; and at least one instrument member pivotally connected to a pivot pin, the pivot pin being coupled to the distal end of the tubular member thereby preventing axial movement, a portion of the at least one instrument member being adapted to slidingly engage the at least one boss.
