By being set into a structure of a liquid outlet seat 8, a connecting bolt 6 and a spring 7, the liquid outlet seat 8 will not come into rigid contact with the anastomosis device 9 when pressed down, thereby avoiding damage to the anastomosis device 9.

[0038] When the circular stapler 9 is being formed, the circular stapler 9 is placed on the base 5 in the protective sleeve 3 and positioned by the central positioning protrusion 501 and several positioning columns 502. Then the upper mold base 1 descends and closes the mold with the lower mold base 2. The upper pressure block 4 contacts the circular stapler 9. Then the electrodes of the stapler 9 and the tooling are connected. Then the electrolyte is introduced into the upper flow channel 101, so that the electrolyte flows from the upper flow channel 101 through several liquid outlets 402 and flows to the molding surface of the circular stapler 9 for continuous flushing. It is then gathered through several liquid outlet side holes 801 and then flows out through the liquid outlet center hole 802 into the lower flow channel 201. As the upper mold base 1 continues to slowly feed the circular stapler 9, the circular stapler 9 is continuously dissolved by the contoured protrusion 401 on the bottom end face of the upper pressure block 4, and the electrolysis product is continuously carried away by the high-speed flowing electrolyte. Finally, the circular stapler 9 is formed.

[0039] The utility model provides an upper die base 1, a lower die base 2, an upper pressure block 4, a base 5 and a flow channel structure, so that the circular anastomosis device 9 can be quickly positioned and placed through the contoured positioning structure on the base 5. Through the contoured protrusion 401 at the bottom of the upper pressure block 4 and the flow channel structure of the entire tooling, the tooling and the anastomosis device 9 are connected to the electrodes during processing and the electrolyte continuously flows through the processing gap at high speed, so that the circular anastomosis device 9 is finally formed. The processing operation is relatively simple and efficient, and the overall tooling structure is simple and the manufacturing cost is low.
