Abstract
Grant Number: 5R44AR051282-03 Project Title: Precision Freehand Sculptor
PI Information: Name Title MOODY, JAMES moody@bluebelttech.com Abstract: DESCRIPTION (provided by applicant): Adult reconstructive orthopaedic procedures represent a significant, growing class of surgeries. Minimally invasive surgery (MIS), though challenging, has multiple benefits to the patient and healthcare providers. The Precision Freehand Sculptor (PFS), a handheld tool for enabling MIS, assists the surgeon in accurately cutting predetermined shapes in bone. It provides a layer of safety and accuracy and can be applied required over a range of procedures. Project Hypothesis: The PFS can provide the advantages of MIS to both patients and the healthcare industry without compromising accuracy. The Phase II Aims are: 1: Determine ideal tracking modality for PFS - Assess the viability and relative advantages of using electromagnetic tracking with the PFS. 2: Show that the PFS can be used to perform UKR more accurately using MIS than the conventional procedure, without adding significant time to the procedure. 3: Refine control algorithm and user interface based on Aim 2 trial feedback 4: Design and construct an OR-compatible PFS - Improve the prior design to optimize a new tool for used in cadaveric and eventual human trials. 5: Prove feasibility of PFS in the OR setting during cadaver trials - Show feasibility of an MIS PFS unicondylar knee replacement procedure (UKR). Evaluate accuracy, procedure time, and OR ergonomics compared to standard techniques. Once feasibility of the PFS is shown for UKR, it can be applied to a wider range of orthopaedic procedures, increasing the market for the device while providing further savings to the healthcare providers by providing a general solution to this broader range of applications.
