Semi-automatic suturing device for minimally invasive cardiac surgery

摘要

Semi-automatic suturing device for minimally invasive cardiac surgery (MICS) was developed. Exchange of the needle is attained by an automatic grasping action and the needle shift parallel to the long axis of the device. This device (5 mm in diameter) can be inserted through a 5 mm trocar. This new device facilitates not only operative procedure such as mitral valve replacement and patch closure during MICS but conventional cardiac surgery.
