超级显微外科血管吻合训练模型的进展

Advances in super-microsurgery vascular anastomoses training model

随着超级显微外科技术的发展,目前主流的两种操作训练模型--离体鸡翅血管模型和活体实验鼠血管模型,逐渐不能满足需要。为了训练吻合直径小于0.8 mm的血管,特别是直径小于0.3 mm的血管,离体动物血管的灌注标本存在一定的局限性,而活体动物模型面临着获取困难、对后勤保障要求高的问题。以活体动物雏鸡为模型有望建立一种较为经济、低风险、高成效,可反复训练、可用于科学研究的超级显微外科模型;其分支可以满足超级显微外科领域直径小于0.8 mm的血管要求,可以模拟正常的血流动力学变化,更接近临床真实操作。但是,活体动物雏鸡模型尚有不足之处,在技能训练或科学研究的过程中,需要建立一套稳定的血管模型及其评价系统,并在术中对雏鸡进行麻醉。

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.
