ABSTRACT
The current mainstream training models for vascular suturing in microsurgery include the invitro chicken wings, legs, and experimental mouse in vivo. With the development of super-microsurgery, it needs to complete super-microsurgery training in a vessel less than 0.8 mm, especially less than 0.3 mm. These training models gradually don't meet the needs. The perfusion specimens of in vitro vessels have several limitations, while vessel models in vivo are faced with the problems of difficulty in obtaining and high logistical support. Vessel model used chickabiddy in vivo is expected to establish a relatively economical, low-risk, high-efficiency, training repeatable and good for scientific research training model in super-microsurgery. Its vessel branches can meet the requirements for vessel diameter less than 0.8 mm. It can be used in continuous training by clinicians and can also meet the pathophysiology and hemodynamic research needs in super-microsurgery field. However, it is necessary to establish a stable vessel model and its evaluated system, as well as an intraoperative anesthesia method for the chickabiddy vessel in vivo model.
