Tissue closure device

A tissue closure device, comprising:

• first clamping parts and second clamping parts configured to clamp tissue, wherein each of the first clamping parts comprises a first clamping arm and a supporting arm rotatably connected to the first clamping arm, and the supporting arm comprises a curved section and a straight section;
• one end of the curved section is fixedly connected to the straight section, and the other end is rotatably connected to the first clamping arm;
• or, an end of the curved section is fixedly connected to the straight section, and an end of the straight section away from the curved section is rotatably connected to the first clamping arm;
• and
• the first clamping arm and the supporting arm are movable between an open position and a closed position, and when the first clamping arm and the supporting arm are in the closed position, the first clamping arm and the second clamping part are close to each other.

A tissue closure device, comprising:

• first clamping parts and second clamping parts configured to clamp tissue, wherein each of the first clamping parts comprises a first clamping arm comprising a connecting section and two supporting sections;
• two ends of the connecting section are separately connected to the two supporting sections, and the end where the connecting section is located is a free end of the first clamping arm;
• each of the supporting sections comprises a curved segment and an extending segment;
• one end of the curved segment is connected to the extending segment, and the other end is connected to the connecting section;
• and
• an end of the curved segment away from the extending segment is not in the same plane as the extending segment, so that the connecting section is away from the longitudinal central axis of the tissue closure device.
