Adjustable-position limb and/or instrument support arm for medical tables

摘要

An adjustable-position support arm for a medical table, the adjustable-position support arm comprising:
a plurality of tubular elements connected to one another in series at a plurality of joints;a locking mechanism disposed at each joint so that a first portion of the locking mechanism is secured to a first tubular element of that joint and a second portion of the locking mechanism is secured to the second tubular element of that same joint, wherein the locking mechanism is normally configured in a locked condition so as to prevent rotation of the first tubular element relative to the second tubular element, and further wherein the locking mechanism may be selectively reconfigured in an unlocked condition so that the first tubular element is rotatable relative to the second tubular element; andan actuator for simultaneously reconfiguring all of the locking mechanisms from their locked condition to their unlocked condition, whereby to permit the plurality of tubular elements to be rotated about the plurality of joints.
