In minimally invasive surgery (MIS), intracorporeal suture and knot-tying is very complex and time-consuming. A knot-tying device with turntable disk has been proposed previously. This device could perform winding and passing suture simultaneously inside body by simply turning the disk through a bevel gear, which significantly reduced the difficulty. However due to one end of suture was fixed to the disk, it was difficult to use this device for continuous suture.
