Abstract: A connector includes a first housing having a bore hole terminating in a machine taper tunnel, a tapered hole, and a slot extending through the first housing across its bore hole to its tapered hole. Similarly, a second housing has a bore hole, a tapered hole, and a slot extending through the second housing across its bore hole to its tapered hole. A rod disposed in the first and second housings' bore holes extends across the slots. The rod terminates at first and second ends with the second end being coupled to the second housing. The rod has a machine taper coupled thereto between its first and second ends for engagement with the machine taper tunnel. A lever, pivotally coupled to the rod's first end, can simultaneously cause the rod's machine taper to move relative to the machine taper tunnel and cause the width of the slots to change.

Abstract: An aneurysm clip includes a compression spring having a compression axis, a first end, and a second end. A first force receiving surface is coupled to the first end of the spring, and a second force receiving surface is coupled to the second end of the spring. A first arm coupled to the first force receiving surface is approximately parallel to the spring's compression axis. A second arm coupled to the second force receiving surface is approximately parallel to the spring's compression axis. A first clamping leg coupled to the first arm extends approximately perpendicular therefrom, and a second clamping leg coupled to the second arm extends approximately perpendicular therefrom. The first and second clamping legs oppose one another and are biased into contact with one another by the spring.

Abstract: A device for positioning and locking a head clamp in a selective position including a first arm, a second arm and a third arm. The third arm having a free end including both a spherical member carried in a socket and including a mounting tube and a gripping device to restrain movement of said spherical member. The head clamp includes a mounting post for insertion to said mounting tube wherein said mounting tube includes a releasable locking device for engaging and holding said mounting post against rotation and withdrawal of said mounting tube to prevent accidental release of the mounting post.

Abstract: A patient head clamp is provided with two pairs of interconnected arms arranged so that the sleeves carrying skull penetrating pins will maintain the pins in alignment with the limits of the spatial separation of the arms of clamp.

Abstract: A device for precisely positioning and locking an object in a selective position including a first arm, a second arm, a third arm and a fourth arm, as well as an L-shaped arm connecting the third and fourth arms. The arms are structured so as to movably connect a support for an object, such as a head rest, to a base member, such as an operating table. The arms are structured so as to slidably engage with one another in order to allow positioning of the support for the object in any desired position in a three dimensional space. The first arm is slidably mounted to a connection to the base member.

Abstract: A device for precisely positioning and locking an object in a selected position includes a first arm member having one end for engaging a base support and for clamping the base support and an opposite end on which is rotatably mounted a bracket in a clamping device at the second end; the first arm member includes a single locking lever for actuating simultaneously both of the clamping devices; the bracket member is pivotably connected to a second arm member which has clamping devices at its opposite ends and a single locking lever for actuating and releasing the clamping devices.

Abstract: An articulatable, rotatable, surgical clamping device which includes an upper handle portion connected to a fixed collar which acts on a center spindle element. The center spindle element subtended by a fixed collar slidingly engages clamp extender elements so as to alternately pull them towards each other or apart so as to clamp the clamping elements. The clamp extender elements being separated from the handle elements by a rotatable cuff which allows free rotation between the plane of articulation of the clamp elements and the plane containing the handle portions.

Abstract: A universal joint which permits global positioning of an object and a locking mechanism for securely and positively locking the universal joint in any position to which it can moved. The universal joint of the present invention may be used in series or singly to provide a mechanism for positioning and locking an object such as, for example, a headrest or a lamp, in any position within a spherical range.
