Patent number: 6599309Abstract: A miniature articulated tip instrument for surgical and like uses, comprising: a thumb housing with an elongated fixed jaw assembly mounted thereto and extending therefrom. A movable jaw actuator member is slidably mounted in a groove formed in the said fixed jaw assembly, the proximal end of the actuator member being seated in a finger housing which is mounted to and spring biased from the thumb housing. A movable jaw defining at least one arcuate projection extending therefrom for pivotal engagement with the actuator member is additionally provided with a second arcuate projection and a concnetric cutout on its opposite side from the second arcuate projection to engage the fixed jaw member and provide a pivot point. The actuator member drives the movable jaw member in a pivoting motion within a throughgoing slot formed in the fixed jaw member within a range of movement with respect to the fixed jaw assembly between extended and retracted positions for effecting selective user controlled working movement.Type: GrantFiled: August 22, 2000Date of Patent: July 29, 2003Assignee: TNCO, Inc.Inventor: Brian W. Gilman

Patent number: 6019780Abstract: A miniature articulating tip for an endoscopic instrument comprising a jaw with a curved slot through which two pivot lugs pass and are anchored in or integral to a fixed outer tip. The two pivot lugs guide the jaw over a path defined by the curved slot and provide stops at the ends of the curve.Type: GrantFiled: January 30, 1997Date of Patent: February 1, 2000Assignee: TNCO, Inc.Inventors: Giuseppe Lombardo, Francis J. DiFrancesco, Brian W. Gilman, Roger M. Burke

Patent number: 6015426Abstract: A rotatable linkage for use in handling small objects at a distance, for example, in endoscopic surgery, by converting the longitudinal motion of a drive member to the opening and closing of jaws at the distal end of the drive member wherein the drive member is enclosed in an elongated housing on which the jaws are mounted which may be rotated relative to the drive member on a bearing by rotation of the housing.Type: GrantFiled: February 27, 1997Date of Patent: January 18, 2000Assignee: TNCO, Inc.Inventor: Jerry Richard Griffiths

Patent number: 5893875Abstract: A detachable and replaceable end effector assembly. The detachable mechanism is made of standard end effectors attached to an actuating tip and pinned inside a yoke assembly. Replacement is made by pulling back a spring loaded radial lock 90, to disengage two rear tabs 51 on the outer tip 50. The yoke assembly is then rotated 90 degrees to disengage the rear yoke pin 9 from the tubular shaft 70. This rotation of 90 degrees also unlocks the T-bar 45 from the front "T" slot of the long actuator 80. The end effector or jaw assembly is then free to be pulled away from the remainder of the shaft. In addition there is a bayonet connection to hold the parts together and prevent accidental disconnection.Type: GrantFiled: May 15, 1997Date of Patent: April 13, 1999Assignee: TNCO, Inc.Inventors: Paul D. O'Connor, Christopher M. Batchelder, Giuseppe Lombardo

Patent number: 5766196Abstract: A medical instrument with a steerable distal end, having a handle for actuating the instrument, a distal operating section for performing a medical procedure, a middle section connecting the handle with the operating section, at least a portion of the middle section being bendable, and steerable means within the bendable portion for permitting the operating section to be controlled in direction at an angle with respect to the axis of the middle section. There are means for rotating the distal operating section into any desired angular position with respect to the longitudinal axis of the middle section. A control member control the direction of movement of the bendable section in three dimensions whereby the distal end may be positioned in any place on or off of the longitudinal axis of the middle section. A protective sheath may be disposed over the bendable section.Type: GrantFiled: October 30, 1996Date of Patent: June 16, 1998Assignee: TNCO, Inc.Inventor: Jerry Richard Griffiths
