Abstract

A mechanism with a remote center of rotation, intended for use in medicine, and in particular, minimally invasive operations, is discussed. The basic mechanism consists of two parallelograms with common links, which allows the surgical instrument to duplicate the movement of the drive link of the mechanism. To ensure greater rigidity of the mechanism, it is proposed to introduce drive redundancy through the use of an additional RRR dyad with a drive pair. The position problem has been solved for the resulting mechanism. A 3D model and a prototype of the mechanism have been also presented.

具有远程旋转中心的平行机械手的结构、运动学和原型设计

摘要本文讨论了一种具有远程旋转中心的机构，旨在用于医学，特别是微创手术。基本机构由两个具有共同链接的平行四边形组成，使手术器械能够复制机构驱动链接的运动。为了确保机构具有更高的刚度，建议通过使用额外的带有一对驱动的 RRR 二联体来引入驱动冗余。由此产生的机构的位置问题已经解决。此外，还展示了该机构的三维模型和原型。
