Abstract
A tissue gripper (60), includes a connecting frame (62) and two gripping arms (64). The connecting frame (62) includes two spaced connecting pieces (623), and the two gripping arms (64) are respectively arranged at sides of the two connecting pieces (623). Each gripping arm (64) includes a bending section (641) connected to the corresponding connecting piece (623) and a gripping section (643) connected to the bending section (641). The width of the bending section (641) is less than the width of the gripping section (643) and the width of the connecting piece (623), such that the weight of a valve clamping device (100) can be reduced, and the pulling force to pull the two gripping arms (64) up to a central axis can also be reduced. Also provided is the valve clamping device (100) provided with the tissue gripper (60).
