PROBLEM TO BE SOLVED: To provide a blood vessel everting instrument capable of easily reversing the end of a blood vessel inside out in a short time without damaging the blood vessel. SOLUTION: This blood vessel everting instrument 1A comprises a ring part 2 that is formed with a linear body bent substantially annularly and can be inserted from the opening of the end of the blood vessel, and a support part 3 formed of a pair of arm parts 31a and 31b. In a substantially half circumference part on the downside of the ring part 2, the linear body reduplicated. The arm parts 31a and 31b respectively comprise plate-like grabbing parts 32a and 32b and inserting parts 33a and 33b fixed to their tips. The tips of inserting parts 33a and 33b are connected to one end 21a and the other end 21b of the linear body forming the ring part 2, respectively. The grabbing parts 32a and 32b are grabbed by a hand to apply a force in the direction of the arrow on the colored background in Fig. 1 to expand the ring part 2. |
