Abstract
Catheter based operations are increasingly being used as a minimally invasive surgery method. In endovascular coil embolization, two surgeons generally fill an aneurysm with embolization coils by the collaborative manipulation of a microcatheter and a coil delivery wire. Currently, medical robot systems are being developed to assist advanced minimally invasive surgery procedures and to overcome the shortage of medical specialists. In this study, a new surgery system that can be operated by only one surgeon is developed. This system consists of a foot switch controlled delivery wire driving unit, a wire insertion force sensor unified Y-connector, and an audio insertion force feedback speaker. Basic verification for this system was conducted using a silicone dummy aneurysm. The results confirmed that the delivery of the wire at a constant velocity by the wire delivery system is an effective method for coil delivery, and that only one surgeon can perform the same coil embolization procedure. In this paper we demonstrate the above said system features and the verification results of this system by conducting a coil embolization using a silicone dummy aneurysm.
