血管外科是一项技术要求很高的外科专业，其中一个组成部分是通过患病血管壁准确放置缝线。微小的错误可能导致血栓形成和手术失败。要发展必要的技能需要许多小时的练习，而过去，这些练习都是在手术台上获得的。使用虚拟工具重建手术环境提出了许多研究挑战。传统的碰撞检测方法对于可变形体是失败的，并且不提供同时在不同区域上缩放响应的机制。我们已经开发了一个线程碰撞测试，允许网格更新，同时保证触觉设备的平滑力响应。有限元法（FEM）是适合允许多个点的接触和该模型的有效性进行了讨论，相对于已知的组织行为。经过临床医生的初步检查，介绍了一种新的方案，用于模拟更真实的力响应
Vascular surgery is a technically demanding surgical speciality, one component of which is the accurate placement of sutures through a diseased vessel wall. Minor errors can result in thrombosis and failure of the procedure. To develop the necessary skills takes many hours of practice, which, in the past, have been acquired at the operating table. Recreating a surgical environment using virtual tools presents a number of research challenges. Conventional collision detection methods fail for deformable bodies and do not provide a mechanism to scale the response over different regions at the same time. We have developed a threaded collision test allowing the mesh to be updated whilst guaranteeing a smooth force response for haptic devices. The finite element method (FEM) is adapted to allow multiple points of contact and the validity of this model is discussed with respect to known tissue behaviour. Following a preliminary examination by clinicians, a novel scheme is introduced for simulating more realistic force responses
