Basic Characteristics of Handheld Robotized Systems in Orthopedic Surgery

Abstract

The advanced tendency in development of robots oriented to orthopedic manipulations is maximally simplification of their mechanics. So called Handheld Robotized Systems appear. Here handheld bone drilling robotized system ODRO (Orthopedic Drilling Robot) is considered. The purpose is to compare its functional characteristics with the similar systems known in the literature. Experimental results are presented for porcine femur drilling by new drill module. The stop drilling decision is taken automatically. The information about experiments concerning the different modes is shown on the display after the drilling end. Handheld robotized systems can perform the accuracy and precise work like the stationary multifunctional robots. They do not need special software, pre-operative planning procedures, calibration, registration and systems for intraoperative navigation. In the same time they are much cheaper, accessible for usage, convenient for work and maintenance which will facilitate their mass application in the orthopedic surgery practice.
