System of the present invention is a kind of automatic sewing device comprising: a shell, an interlinked mechanism, one are for line portion, a lead wires pierce portion and a clamp electricity burning portion. The what shell is closed,With space in a shell； And the interlinked mechanism system sets in the what shell in space； This is for system, line portion to provide a suture； The what lead wires pierce portion is closed,It is with a puncture tip,One pierces through pipe portion and a lead channels； The system, lead wires pierce portion is driven by the interlinked mechanism and can pierce through front position to a puncture Hou position by one； The clamp electricity burning portion,Its suture temporarily to be clamped and is heated more than the expansion temperature,And the predetermined position of suture is made to expand and form a knot； ThereforeThe present invention has both the advantages that suture is quick and suture is easy and effect.本發明係為一種自動縫合裝置，其包括：一殼體、一連動機構、一供線部、一引線刺穿部及一夾線電燒部。關於該殼體，具有一殼內空間；而該連動機構係設於該殼內空間內；該供線部係用以提供一縫合線；關於該引線刺穿部，其係具有一刺穿尖端、一刺穿管部及一引線通道；該引線刺穿部係被該連動機構帶動而可由一刺穿前位置至一刺穿後位置；該夾線電燒部，其用以將該縫合線暫時夾住並加溫超過該膨脹溫度，而使得縫合線之預定位置膨脹而形成一個結；故，本發明兼具縫合快速及縫合容易等優點及功效。
