<P>PROBLEM TO BE SOLVED: To provide a suture instrument for the trachea which is suitable for suturing, anastomosis, or ligation of the trachea or a bronchus under an endoscope. <P>SOLUTION: The suture instrument for the trachea includes an outer cylinder of hollow structure having an opening in a side face near the distal end; a shaft slidably inserted through the hollow part of the outer cylinder; a holding part fixed to the proximal end of the shaft; and a suturing curved needle arranged in the opening of the outer cylinder. The outer diameter of the outer cylinder is 1-5 mm. The shaft and the suturing curved needle have bevel gears meshed with each other respectively, and are connected to each other through the bevel gears. When a user rotates the holding part located on the front side, torque is transmitted to the suturing curved needle through the shaft and the bevel gears to rotate also the suturing curved needle located near the distal end. <P>COPYRIGHT: (C)2012,JPO&INPIT |
