A Steerable Drill for Minimally-invasive Surgery

In conventional core decompression of osteonecrosis, surgeons cannot successfully reach the whole area of the femoral head due to the rigidity of the instruments currently used. To address this issue, this invention is a steerable drill using a continuum dexterous manipulator (CDM) and flexible cutting tool passing through the lumen of the CDM. Effective...

Variable Stiffness Steerable Cutter (Drilling, milling, etc) Using Low Melting Point Alloys

A new type of cable-driven continuum manipulator (CM) is presented, in which the stiffness of the device along its body length can be controlled using the thermomechanical properties of a phase changing alloy. The liquid phase of the alloy is used for achieving high dexterity and the solid phase for high stiffness. Joule heating and water cooling is...

An Oscillatory Atherectomy Device Incorporating a Novel Burr Design and Torque Limiting System for the Safer Treatment of Advanced Coronary Artery Disease

Unmet NeedCardiovascular disease is the leadind cause of death globally and the most significant cost contributor to the health care system. When coronary plaques become heavily calcified - which is typical in older patients with long-standing coronary disease and those with co-morbidities such as chronic kidney disease - the compliance of the vessel...

VERTEBRAL OSTEOTOMY SAW GUIDE

Unmet need: En bloc resections of tumors in the spine require multiple osteotomies to free the specimen from the spinal column. Osteotomies through a vertebral segment can be performed in many different ways, such as using osteotomes, drills, reciprocating saws, and wire saws. Yet, existing techniques are prone to unintentional cutting of adjacent critical...
