  • the holding unit 20 of the second holding body 4 has the second pseudo blood vessel BV2 at a predetermined insertion position with respect to the shaft member 52. It has a clip 50 for fixing. Therefore, the second pseudo blood vessel BV2 can be reliably fixed to the holding portion 20, and a stable anastomosis operation can be performed.
  • the elastic holding member 15 can be pulsated, so that the movement of the elastic holding member 15 can be regarded as the heartbeat, and can be opened.
  • the environment can be reproduced closer to the coronary artery anastomosis environment in thoracic surgery.

Abstract

L'invention concerne un accessoire d'entraînement destiné à l'anastomose vasculaire qui permet à une personne d'améliorer de manière efficiente et efficace ses compétences en manière d'anastomose vasculaire avant d'acquérir de l'expérience clinique dans des gestes chirurgicaux difficiles tels que le pontage coronarien. Un accessoire d'entraînement (1) destiné à l'anastomose vasculaire comprend deux simulations de vaisseaux sanguins (BV1) et (BV2) qui sont fixées librement sur un site d'anastomose grâce à un premier (2) et un second (4) support. Grâce à cette structure, il est possible de créer des environnements proches de ceux rencontrés en expérience clinique, ce qui permet à une personne d'améliorer de manière efficiente et efficace ses compétences en manière d'anastomose vasculaire avant d'acquérir de l'expérience clinique dans des gestes chirurgicaux difficiles tels que le pontage coronarien.
