    • An intracardiac suture device comprises a first shaft assembly 1 including a first shaft 11 and a first suture needle-holding device 4 provided at a distal end of the first shaft 11; a second shaft assembly 2 comprising a second shaft 21; a third shaft assembly 3 comprising a third shaft 31 and a handling portion 33; and a puncture assembly 5 provided at a proximal end thereof with a second suture needle-holding device 51. The second shaft 21 is protrusible by sliding-movement from the distal end of the first shaft 11 toward the first suture needle-holding device 4, and a suture needle 6 is transferable between the first suture needle-holding device 4 and the second suture needle-holding device 51 when the third shaft 31 is slid to the distal end of the second shaft 21 after sliding the second shaft 21 to a position where a suture site is held between the second shaft 21 and the first suture needle-holding device 4.
    • 心内缝合装置包括第一轴组件1,其包括设置在第一轴11的远端处的第一轴11和第一缝合针保持装置4; 包括第二轴21的第二轴组件2; 包括第三轴31和操纵部33的第三轴组件3; 以及在其近端处设置有第二缝合针保持装置51的穿刺组件5。 第二轴21通过从第一轴11的前端向第一缝合针保持装置4的滑动而伸出,缝合针6能够在第一缝合针保持装置4和第二缝合针 在将第二轴21滑动到第二轴21和第一缝合线保持装置4之间的缝合部位的位置时,第三轴31滑动到第二轴21的前端的夹持装置51。
