The present invention provides a tissue closure device, comprising: a first clamping base and a second clamping base which may be opened/closed relatively and form an accommodation cavity after being closed; and a pouch assembly which may be driven to move in the accommodation cavity, wherein: the pouch assembly comprises a staple pusher, a pair of needle heads movably connected to the staple pusher, and a connection portion connected to the proximal ends of the pair of needle heads; and when the staple pusher moves from the proximal end to the distal end, the pair of needle heads pushes a tubular tissue located in the accommodation cavity to the distal end until the distal ends of the pair of needle heads are closed to close the tubular tissue into a purse string. A bundled purse string with a gathered center may be formed through the tissue closure device.
