Surgical instrument and method for use in hand-assisted laparoscopy |
摘要 |
A surgical instrument and the method for delivering and withdrawing surgical tools through a cannula in an abdominal cavity during hand-assisted minimally invasive surgery. A tube slidably extends through a cannula with a slender surgical tool such as a suture needle holder, secured in a snap-in gripper at the insertion end of the tube. The thumb and fingers of one hand of the surgeon or an assistant's cause the tube to move axially from a fully retracted position in the cannula to a position where the tool projects from a snap-in socket in the tube a length sufficient for a surgeon's hand to grip a knurled surface around the tool. A detent bead around the periphery of the tool snaps into a complementary groove within the gripper. Insufflating gas may be introduced or vented as needed through a port which communicates through the interior of the tube with the abdominal cavity. The procedure is reversed for withdrawing the tool. |
