Tissue clamping system

A tissue clamping system, comprising a tissue clamping device and a driving component, wherein the tissue clamping device comprises a clamping part, a first supporting part, a second supporting part, and a restricting part;

• the clamping part comprises at least two supporting arms and at least two clamping arms in one-to-one correspondence with the at least two supporting arms, the at least two supporting arms are provided on the first supporting part, and the at least two clamping arms are provided on the second supporting part;
• the second supporting part comprises a guiding element, and the restricting part passes through the first supporting part and is fixedly connected to the first supporting part;
• the driving component passes through the restricting part and is detachably connected to the second supporting part, and the driving component is configured to drive the at least two supporting arms to expand or close radially with respect to the restricting part, so that the at least two clamping arms expand or close radially with respect to the restricting part;
• in a closed state, a distal end of the restricting part is housed in the guiding element such that the distal end of the restricting part is housed in the guiding element at the first moment when the supporting arm is expanded.
