Abstract: A device and method is provided for a trackable suction tool for surgical use. The suction tool provides multiple configurations for the tip and reference tree, while allowing tracking by a navigation system. The tip and reference tree are attached to the suction tool handle by a snap fit, a threaded ring with key and slot connections or semi-Allen key connections, providing specific rotational configurations of the tip, handle and reference tree with each other. The handle may include a rotatable outer sleeve with a tear-shaped orifice for suction regulation and an inner sleeve with a corresponding opening, allowing variable placement of the tear-shaped orifice relative to the longitudinal axis of the suction tool. The features of the device allow a suction tool with multiple configurations to be trackable with a navigation system.

Abstract: A navigation arm system for supporting a navigation device of a navigation system, capable of coupling with a navigation display cart, the navigation arm system involving: an arm assembly configured to position the navigation device, the arm assembly including a first arm linkage having a tension adjustment feature and releasably connectable to the navigation device; a second arm linkage capable of connecting the arm assembly to the navigation display cart; and at least one joint coupling at least the first and second arm linkages; and a locking mechanism configured to maintain a disposition of the arm assembly in relation to the navigation display cart in a locked stored position and a unlocked deployed position, the locking mechanism configured to lockably couple the arm assembly in relation to the navigation display cart, the locking mechanism including a plurality of locking modes, whereby structural stability is providable

Abstract: A snap-fitted arrangement of a valve on a pump includes means of which at least one is elastic such that one of the means is integrated with the valve and the other means is integrated with the pump. The means are arranged in a complementary manner in a linear engagement of the male-female type such that the elastic means elastically deforms during engagement. One of the means includes a channel and the other means includes a protuberance which engages the channel.

Abstract: The invention relates to an assembly for an electrically operated valve in the automotive field aimed to increase the injection pressure of fuel distributed to combustion chambers, said assembly comprising both a coil unit, wherein a solenoid can control the movements of the electrically operated valve in a housing along a given axis, and an hydraulic unit to provide fuel at the injection pressure, a clip ring being located into a cavity of the coil unit and a cavity of the hydraulic unit to maintain the coil unit and the hydraulic unit associated. The invention is characterized in that the coil unit presents a plurality of slots providing access to the clip ring, across the coil unit, from the exterior of the assembly.
