摘要:
A method of designing a guide tool for cartilage repair in an articulating surface of a joint, comprising the steps of: I. determining physical parameters for cartilage damage in a joint and generating design parameters for cartilage repair objects and their relative placement in a predetermined pattern, comprising: II. selecting repair objects to fit the individual cartilage damage site wherein the repair objects have: cross sectional areas adapted to fit the surface area of the cartilage damage site, lengths adapted to fit the selected joint and/or type of cartilage damage, and surfaces intended to align with the articular cartilage surface in the joint, based on the healthy surface contour curvature, III. determining, based on obtained image data, positions and angles of the selected cartilage repair objects, wherein the positions and angles are adapted so that the selected repair objects fit the individual cartilage damage site, IV. generating design parameters of the guide tool, for placement of the cartilage repair objects comprising the following steps of: generating the design for an upper part and a lower part of a guide channel in a guide body extending from the positioning body, said guide channel passing through said positioning body and said guide body wherein the angles and positions are generated dependent on and substantially corresponding to the determined angles and positions of the selected cartilage repair objects, and wherein the design for the lower part of all the guide channel is generated dependent on and substantially corresponding to the determined cross sectional areas, of the selected cartilage repair objects.

A molding arrangement serves for molding articles at each stroke of an injection-molding machine in which an injection mold is mounted. The articles are composed of components made of different materials in cavities formed in the injection mold, with each cavities corresponding to the shape of a component whereby identical cavities are separated by angular distances and placed at equal distances from a central axis of the injection mold and parts of the cavities are formed in a separately movable section of the movable mold half. The injection molding arrangement includes an operation part for displacing the section to-and-fro between closed and open positions of the injection mold and in open positions to turn the section about the central axis angles corresponding to the angles between the cavities to form whole cavities in the injection mold in closed position.

A percutaneous ostomy implant for implantation into the abdominal wall of a patient is provided, which includes a connecting member for mounting an external detachable device thereto; a first tubular ingrowth member depending from the connecting member; and a second tubular ingrowth member depending from the connecting member and being radially outwardly spaced from the first tubular ingrowth member. The first tubular ingrowth member is configured and dimensioned to receive a bowel segment within it to allow the stoma and serosal tissue of that bowel segment to infiltrate the first tubular ingrowth member. The second tubular member is configured and dimensioned to abut dermal tissue to allow the dermal tissue to infiltrate the second tubular ingrowth member, thereby securing and sealing the ostomy implant to the dermis.
摘要:
An implant for percutaneous implantation through the abdominal wall for encircling and engaging an externalized length of a body duct of a human or animal patient. The implant has an exterior ring section protruding outwardly from the abdominal wall with a free end which serves for mounting of a detachable device, and an interior section extending through the abdominal wall and inside the patient for internal fixation of the implant. The exterior ring section and interior section have a common axis. The internal circumference of at least a part of the exterior ring section above the interior section is arranged with a biocompatible, integrated ingrowth means for the exterior surface of the body duct wall.
摘要:
A mechanical interface for transferring a reciprocating movement from one element to another element releasably mountable thereto. The interface comprises at least three interface points, at least two of which being laterally spaced apart, and at least two of which being longitudinally spaced apart. A motion generator provides a reciprocating movement, which is transferred from the one element to the other element via at least one of the interface points. The interface point(s) transferring the movement includes contact portions having curved contact surfaces, such that the curved contact surfaces are in abutment with opposing contact surfaces of the interface point when the elements are mounted, thereby transferring the reciprocating movement.

An injection-moulding system for an injection-moulding machine including a clamping assembly, a temperature-adjusting system, and an ejector. The clamping assembly comprises two horizontal beams for mounting on the platens of the injection-moulding machine and two vertical beams for crosswise mounting on the horizontal beams in multiple positions. The clamping assembly allows dies of various sizes to be clamped in one and the same machine. The temperature-adjusting system includes at least one cooling tube for detachable insertion into a blind hole formed in the die. The cooling tube is attached to coolant conduits which are permanently attached to a source of coolant. Dies can thereby be replaced quickly and easily without spilling any coolant. The ejector is adapted to eject the cooled product after opening of the die. The injector pins are in an inexpensive way glued to the ejector plate. Use of the injection-moulding system provides considerable cost savings over conventional devices.

An applicator for cleaning the inside of pipes and hoses is disclosed. The applicator comprises a pressure chamber and a lid which is adjustable between open and closed positions, sealing the pressure chamber in the closed position. A sealed plane interfaces is provided between the pressure chamber and the lid which is guided for displacement transversely of the axis of the nozzle between the open and closed positions and is connected to a valve controlled double acting pneumatic cylinder for effecting the displacement. A nozzle to be connected to the pipe or the hose, is provided on the lid and in the closed position thereof communicates with the pressure chamber to be connected to a compressed air source through a valve for propulsion of a rinse projectile inserted into the nozzle, when the lid is open, through the pipe or the hose by means of compressed air being supplied to the pressure chamber with the lid in the closed position.
