Abstract: A prosthetic structure and a method to build the same on at least two mounted implants (or implant analogues). A tubular member is releasably mounted on the respective implant. A body, having a throughput channel, is mounted on the respective tubular member to be displaceable along the same. A bar is inserted between two nearby tubular members, and the distances between the respective nearby pairs of ball-and-socket-like shaped and co-operating surfaces of the bodies and of the bar are eliminated. The bar may be of adjustable length, in order to be fitted shape-wise bondingly between two bodies. Alternatively, one of the bodies may be rotatable on the tubular member thereof. The fitted structure is fixed, for instance, by welding, soldering or agglutination of occurring joints.

Abstract: Bone tissue fragments are collected from liquid fluid being evacuated by suction from a surgical operation in bone tissue. Liquid is allowed to pass into the cylindrical sieve through one open end thereof and through the sieve wall from the inside to the outside thereof. Bone tissue fragments are collected on the inside surface of the sieve and are scraped off and deposited outside the sieve.

Abstract: A rotationally symmetrical anchoring element made of biocompatible material for anchoring into bone tissue. A circumferential surface includes a lower portion adapted to be incorporated with bone tissue and an upper portion that is located outside the bone tissue following implantation. The upper portion is adapted for attachment of a spacer piece or prosthetic structure thereto. The upper portion includes an unthreaded conical portion having a diameter that increases with increasing distance away from an upper end gable surface of the element. The conical portion forms a bearing surface for cooperation with a conical surface of the spacer piece or the prosthetic structure. The conical surface matching the conical portion. An external thread provided at a top of the upper portion secures the conical surface of the spacer piece or the prosthetic structure against the conical portion.

Abstract: A bone implant for implantation into a bone tissue and for the connection of a prosthetic structure thereto, the bone implant including a screw-threaded portion for insertion into the bone tissue, a neck portion extending along an axis from the screw-threaded portion, the neck portion terminating in an end surface, the end surface being provided with a threaded blind hole for attachment of the prosthetic structure to the bone implant, a cover element, and an attachment mechanism for attaching the cover element to the neck portion of the bone implant, the cover element including a cupola-shaped outer surface and the cover element having a thickness extending inward from the cupola-shaped outer surface for a substantial distance along the axis of the neck portion when the cover element is attached to the neck portion by the attachment mechanism.

Abstract: A scalpel comprises a shank having a holder for releasably mounting a surgical blade. A ball of plastic material is formed by injection molding on the blade proper which consists of metal. The holder includes a sleeve, which is threadedly engaged with the shank at one end thereof and adapted to be screwed axially along the shank. The sleeve forms a ball socket, which is adapted to receive the ball of the blade therein. A clamping rod extends axially within the socket between the shank and the ball to engage and disengage said ball by the sleeve being screwed on the shank. The end of the clamping rod, which is adjacent to the ball, forms a circular sharp edge of a diameter which is substantially smaller than the diameter of the ball, thus cutting into the plastic material of the ball when the sleeve is screwed to engage the clamping rod with said ball.
