MRI-compatible Cranial Implants with Imbedded Wireless Ultrasound

Unmet Need: Medical imaging data is crucial for the proper diagnosis and treatment of a number of maladies. For surgeries on the brain, ears, eyes, nose, or throat, biometric imaging data are heavily relied upon in order to diagnose and monitor intracranial pathologies. MRI and CT scans are only intermittently available, are expensive, and do not provide...

Fast and Automatic Periacetabular Osteotomy Fragment Pose Estimation Using Intraoperatively Implanted Fiducials and Single-View Fluoroscopy

Unmet NeedDevelopmental dysplasia of the hip (DDH) is the most common developmental hip deformity in children, and the most common single cause of osteoarthritis of the hip in young and older adults. This condition occurs when there is insufficient coverage of the femoral head by an excessively shallow acetabulum (hip socket). Periacetabular osteotomy...

Universal Gripper Using Phase Changing Material

Unmet NeedCurrent robotics systems that utilize a high degree of redundancy, like endoscopes, are capable of highly dexterous movement but sacrifice rigidity. Though these systems can reach a desired location when they arrive there they can be highly limited in their use on harder tissues and bone because they are unable to bare a significant load....

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...
