Patent number: 6471710Abstract: A probe position sensing system for accurately determining a spatial location in a coordinate system of a distal end of a probe assembly. The probe assembly includes an articulated arm having a pair of sections interconnected by a flexible joint and at least one element. The element extends through the joint and is positioned to be subjected to a degree of flexure due to relative displacement of the sections. A flexure of the element induces a change in a physical property associated with the element. An instrument monitors the physical property and derives an angle between adjacent sections from variations of the physical property.Type: GrantFiled: August 11, 2000Date of Patent: October 29, 2002Assignee: Advanced Sensor Technology, LLCInventor: Frank Bucholtz

Patent number: 5741210Abstract: A clamping device for use in a surgical retractor support includes a first clamp member for clamping a first retractor support. The first clamp member has a first opening that is disposed along a longitudinal axis of the first retractor support for receiving the first retractor support. A pin disposed within the clamp member has a cam surface for acting on the first retractor support member. A handle operable with the pin for moving the cam surface between a first nonlocking position and a second locking position for locking the first retractor support member from movement in a substantially vertical direction. Preferably a wedge section is positioned between the cam surface and the first retractor support such that the wedge section frictionally engages the first retractor support when the cam surface is in the second locking position. The clamping device also has a second clamp member for clamping a second retractor support.Type: GrantFiled: October 10, 1995Date of Patent: April 21, 1998Assignee: Minnesota Scientific, Inc.Inventor: Walter J. Dobrovolny

Patent number: 5460169Abstract: An instrument for assisting surgical laparascopic or coelioscopic operations where the patient's anterior abdominal wall is formed with an aperture and is raised away from the patient's visceral organs comprises a wirelike body having a first part extending substantially in a plane and adapted to lie against the posterior face of the anterior abdominal wall, a second part extending transversely from the plane of the first part, having an outer end, and adapted to traverse the aperture in the abdominal wall, and a hook at the outer end of the second part adapted to be secured to a stationary support. After inflation of the patient's peritoneum to raise the anterior abdominal wall, the second part of the device is hooked under this wall and the outer end is hooked over a bracket to maintain the abdominal wall raised.Type: GrantFiled: June 28, 1994Date of Patent: October 24, 1995Inventor: Philippe Mouret
