4) The blood vessel wall is turned outwards by the microscopic blood vessel forceps, and the nail head on the ring nail penetrates through the blood vessel wall, so that the blood vessel is fixed on the ring nail in a cuff turning outwards manner.
5) And clamping the ring nails after the two blood vessels are assembled on the fixing rod, sleeving the fixing rod on the forceps head of the anastomosis forceps, flushing the blood vessel port again, and confirming that the outer membrane is completely everted and the blood vessel port has no tissue debris and blood clots.
6) Slowly closing the anastomosis forceps until the anastomosis forceps handle is clamped into the tooth position, stopping slightly until the anastomosis forceps handle is fully anastomosed, carefully checking whether the ring nails are tightly involuted, and if necessary, using fine vascular forceps to assist in pressurizing and closing.
7) And loosening the anastomosis forceps, withdrawing the ring nail from the fixed rod, loosening the vascular clamp, determining that the blood flow is smooth, and completing anastomosis without obvious blood leakage.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
