Document Type and Number:
WIPO Patent Application WO/2022/037084
Kind Code:
A1
Abstract:
A tissue clamping member (60), comprising a connecting frame (62) and two clamping arms (64). The connecting frame (62) comprises two connecting pieces (623) which are spaced apart from and opposite to each other; the two clamping arms (64) are respectively arranged at opposite side edges of the two connecting pieces (623); each clamping arm (64) extends to the side distant from the other clamping arm (64); each clamping arm (64) comprises a bent section (641) connected to the corresponding connecting piece (623) and a clamping section (643) connected to the bent section (641) and distant from the corresponding connecting piece (623), and the width of the bent section (641) is less than the width of the clamping 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 needed to pull, by means of control wires, the two clamping arms (64) of the valve clamping device (100) up to attach a central shaft can also be reduced so that the reverse acting force borne by the control wires is reduced, breakage of the control wires is prevented, and operation is facilitated. Also provided is the valve clamping device (100) provided with the tissue clamping member (60).
