Abstract
A surgical tool positioning device for positioning and holding a surgical tool is disclosed. The device includes an adjustable-friction ball and socket joint configured to provide three degrees of rotational freedom. A variable holding force may be applied to the ball via a locking member to selectively lock and unlock the adjustable-friction ball and socket joint. The socket includes a friction-inducing member housed therein and in contact with the ball. When the ball and socket joint is unlocked, this friction-inducing member provides sufficient frictional force to hold a position of the surgical tool. However, this frictional force may be overcome with intentional external forces such as during repositioning of the surgical tool.
