The existing tubular anastomat as shown in chinese patent CN101416895B is mostly dependent on manual single use instrument. In surgery, a surgeon often needs to rotate the distal knob to close the proximal and distal tissue, closing the firing bar with both hands in a reasonable tissue compression zone to complete the anastomosis. In the firing process, a great firing force is needed to achieve a good cutting and suturing effect, and the shaking of an arm caused by the great firing force can lead tissues to be pulled to increase bleeding; moreover, uneven manual striking force can cause poor nail forming effect and cause anastomotic leakage; the manual force is insufficient to cut the tissues and the nails cannot be formed, so that the operation fails; the manual mode closes the tissue, wastes time and energy, increases doctor's operation burden.
Therefore, medical staff is expected to realize tissue clamping in an electric mode and electric percussion, and all risks of the manual anastomat can be avoided. The reusable electric handle provides power output and is connected with the barrel component of the disposable tubular anastomat to realize electric cutting and suturing.
