BONE CUTTING GUIDE USED IN A MEDICAL NAVIGATION SYSTEM

摘要

A bone cutting guide for a medical navigation system is provided to determine a position of a cutting section by checking a cross section of the bone with the naked eye. A bone cutting guide for a medical navigation system includes a cutting block(40), a controlling block(30), a position determining tool(60), and an insertion hole(35). A slit(41) is formed in the cutting block. The slit guides the cut of the bone according to the cross section. The position of the controlling block is controlled for the bone. The cutting block is attached or detached in the mounting unit of the controlling block. The position determination tool has a sensing unit. The position of the sensing unit is recognized by the medical navigation device. The position determination tool determines the position of the cross section. The insertion hole is formed in the mounting unit. The position determination tool is combined in the insertion hole. The sensing unit includes at least three infrared ray reflector(61,62,63).
