Abstract: An implement holding device for use in surgeries is disclosed. The implement holding device includes a flexible arm that defines an inner lumen and that is configured to be coupled to a medical instrument. A tension cable is disposed within the inner lumen and is configured to adjust the rigidity of the flexible arm. Additionally, a tension setting dial is coupled to the tension cable. The tension setting dial includes a plurality of discrete tension setting locators, each locator is configured to be engaged when the tension setting dial is in a position corresponding to the locator, and each locator corresponds to a different cable tension force such that manipulating the tension setting dial to a position corresponding to one of the locators adjusts the cable tension to a specific cable tension force, and wherein changing the dial position is effective to change the rigidity of the flexible arm.

Abstract: A scissor-like assembly having a pair of axially mating and relative slidable elongated shafts each provided with a handle and include an articulating interconnection by which the shafts are simultaneously reciprocable relative to each other and conjointly movable about their common axis. Working tool members are provided at the end of each shaft.
