Title: TISSUE CLOSING DEVICE AND MEDICAL INSTRUMENT
Abstract:
A tissue closing device (100), comprising: a first gripper base (11) and a second gripper base (12) which can open/close relative to each other, the first gripper base (11) and the second gripper base (12) forming an accommodating cavity (13) after being closed; and a purse-string suture assembly (24) which can be driven to move from the proximal end to the distal end in the accommodating cavity (13), the purse-string suture assembly comprising a staple-pushing device (242), a pair of needles (2411, 2412) which are movably connected to the nail-pushing device (242), and a connecting portion (2413) which connects the proximal ends of the pair of needles (2411, 2412). When the nail-pushing device (242) moves from the proximal end to the distal end, the pair of needles (2411, 2412) pushes a tubular tissue within the accommodating cavity (13) towards the distal end, so that the distal ends of the pair of needles (2411, 2412) are closed and thus the tubular tissue is closed as a purse-string suture. The tissue closing device (100) can form a bundled purse-string suture having a concentrated center part.
