A router power tool having a housing and a base, the housing mounted to be moveable with respect to the base. The base and housing are connected by first and second extendable assemblies, at least one of the assemblies including biasing means to bias the housing away from the base. This extendable assembly has a control portion which can be moved, while located with the extendable assembly, from a first position in which the biasing means provides the biasing force and a second position in which the biasing means is released. In one embodiment, the router power tool includes safety stop portions to prevent movement of the tool holder while cutting tool changing is being performed. In another embodiment, a safety stop portion limits movement of at least one of the extendable assemblies when the cover is held by the power switch when in the on position.

A bone graft loading system includes a loading funnel, syringe, cannula, plunger, and loading tool. The loading funnel includes an interior passageway to receive the cannula and a syringe docking portion. The syringe may be coupled to the syringe docking portion so that it extends along a longitudinal axis that is transverse to the longitudinal axes of the cannula and the loading funnel. A user may advance bone graft from the syringe to a holding area of the loading funnel. The user may then move the loading tool through the holding area and into the interior space of the cannula to load the cannula with bone graft. This process may be repeated until the cannula is fully loaded with bone graft. The cannula and the plunger inside the cannula may then be removed from the loading funnel and coupled to an injector assembly for use in surgery.
