ABSTRACT:
A suturing instrument for suturing tissue comprises an elongated housing having opposite ends. A curved suturing needle having a pointed end and to which a suture is attached is supported at one end of the housing for rotational motion about an axis. A driver mechanism in the housing rotates said needle about said axis through successive revolutions. There may also be a suture tensioner in the housing which applies tension to the suture to draw the suture toward the other end of said housing following each revolution of said needle. In its operation, the instrument thus emulates the actions of a surgeon suturing manually.
