Abstract: A device and method for precisely positioning a probe tip relative to a target lesion in a bodily protuberance is provided. The protuberance to be probed is secured between a first and a second radiolucent platform. The platforms are in parallel and spaced relation and the second platform comprises a plurality of passages for insertion of a probe. Radiopaque markers on the second platform aid in locating the lesion in a radiograph of the target taken along a first path through the second platform, target and first platform. Utilizing the radiograph, a probe guide comprising a plurality of passages is positioned immediate the lesion to enable the positioning of a probe coincident the lesion along the first path. A radiopaque scale is positioned coplanar the probe guide to indicate distance along the first path enabling the creation of a second radiograph indicating the depth of the lesion relative to the probe guide and the radiopaque scale.

Abstract: A device for releasably supporting an object, said device including a housing with a space therein and a spring member having a segment thereof disposed in said space and another segment in partial registry with recesses formed by housing side walls.

Abstract: A tool rack providing a pair of transversely spaced tool receiving recesses defined by transversely aligned tool supporting walls; a spring mounted between the walls in position for engagement by a tool inserted in the recesses with the spring positioned to engage a midportion of the tool between the walls and to be resiliently deflected away from the walls to resiliently hold the tool in a three-point support. The walls are preferably inclined to the direction of resilient deflection of the spring and in the direction of increasing the spring deflection upon removal of the tool from the recess.
