DEVICE AND METHOD FOR PRODUCING SPACERS
The invention relates to a device for producing a spacer having a stem mold (1) which has an inner space (2), wherein the inner space (2) is accessible via a proximal opening (3) and wherein the stem mold (1) has a proximal wall (4) which peripherally delimits the proximal opening (3) of the stem mold (1), a head mold (5) which has in the interior thereof a hollow space (6), wherein the hollow space (6) has a spherical surface-shaped inner surface (7) and is accessible via a distal opening (8), wherein the head mold (5) has a distal wall (9) which peripherally delimits the distal opening (8) of the head mold (5), a metal core (10) which has a stem part (12), a head part (14) and a flange (16), wherein the flange (16) projects out from the metal core (10), is arranged between the stem part (12) and the head part (14) and has a proximal surface (18) and a distal surface (20), wherein the stem mold (1) and the stem part (12) are shaped such that the stem part (12) is arranged in the inner space (2), when the proximal wall (4) is resting against the distal surface (20), and wherein the head mold (5) and the head part (14) are shaped such that the head part (14) is arranged in the hollow space (6), when the distal wall (9) is resting against the proximal surface (18).
The invention also relates to a set with such a device and to a method for producing spacers with such a device.
Systems and techniques for restoring and maintaining intervertebral anatomy
Techniques and systems for distracting a spinal disc space and supporting adjacent vertebrae are provided. Trial instruments are insertable into the disc space to determine a desired disc space height and to select a corresponding implant. Implants can be also be self-distracting and the implant providing the desired disc space height can be implanted in the spinal disc space.
METHOD FOR LUBRICATING AN ARTIFICIAL CONTACTING SURFACE
A method for implanting a medical device for implantation in a mammal joint. The method comprising the steps of creating an opening reaching from outside of the human body into the joint, providing said artificial contacting surface to said joint, fixating the artificial contacting surface to the joint, implanting said reservoir in the human body, and lubricating the artificial contacting surface with use of a lubricating fluid contained in said reservoir.
Method for performing surgical procedures using optical cutting guides
A method for performing a surgical procedure on a patient using a robotic system and a navigation system. The robotic system includes a cutting tool. The navigation system has at least one locating device to track a portion of the patient during the surgical procedure. The navigation system provides information as to a position of the portion of the patient. An optical cutting guide is projected onto the portion of the patient to enable cutting of the portion of the patient with the cutting tool of the robotic system while the optical cutting guide is projected onto the portion of the patient.
Assembled implant
This invention is directed to an assembled implant comprising two or more portions of bone that are held together in appropriate juxtaposition with one or more biocompatible pins to form a graft unit. Preferably, the pins are cortical bone pins. Typically, the cortical pins are press-fitted into appropriately sized holes in the bone portions to achieve an interference fit. The bone portions are allograft or xenograft.
HIGHLY LORDOSED FUSION CAGE
A fusion cage has a first component that defines an outside surface that is configured to engage a vertebral endplate, and an interior surface. The fusion cage has a second component that defines first and second opposed surfaces. One of the first and second opposed surfaces can mate with the interior surface of the first component. The fusion cage can include vertical and lateral throughholes adapted to enhance fusion.
Mould for realizing a temporary prosthesis of hip or shoulder, and method thereof
Mould and method for realizing a temporary prosthesis of hip or shoulder, which comprises a shaft and a head. The mould comprises: a first mould portion (1) comprising a first half-shell (2); a second mould portion (3) comprising a second half-shell (4); the first mould portion (1) and the second mould portion (3) being able to be coupled with respect to each other so that the first and second half-shell (2, 4) are counter-faced and define a chamber (5) which conforms a shaft portion (5a), a head portion (5b) and an opening (5c) for injection of a fluid (preferably viscous) material; fixing means (6) for fixing the first and the second portion (1, 3); a first insert (7) comprising a cap portion (8) which is realized as a unique body, is dimensioned to be inserted in the head portion (5b) and is conformed to give shape to the head of the prosthesis. The first mould portion (1), the second mould portion (3) and the first insert (7) are mutually conformed to obtain a temporary prosthesis, when the first mould portion (1) and the second mould portion (3) are coupled together, the first insert (7) is inserted in the head portion (5b) and the fluid (preferably viscous) material is injected in the opening (5c).
DEVICE AND METHOD FOR PRODUCING SPACERS
The invention relates to a device for producing a spacer having a casting mold lower part (1) with a cavity (2), a casting mold wall (3) which extends peripherally away from an edge of the cavity (2) and which is open on the opposite side, a casting mold upper part (5) with a shaping surface (6), wherein the casting mold upper part (5) can be inserted into an interior (4) of the casting mold lower part (1) and is displaceable in the direction of the cavity (2), such that a hollow space is formed which is delimited by the cavity (2), the shaping surface (6) and the casting mold wall (3) and in which the spacer is moldable, at least one container (7) for receiving excess bone cement paste, and at least one opening (8) in the shaping surface (6) and/or in the cavity (2), which opens into the at least one container (7) for receiving excess bone cement paste.
The invention also relates to a method for producing spacers using such a device.
Elbow prosthesis
An elbow prosthesis according to the present teachings can include a stem structure and an articulating component. The stem structure can be operable to be positioned in a bone of a joint. The stem structure can include a stem portion that is operable to be positioned in the bone and a C-shaped body portion having a first retaining mechanism formed thereon. The articulating component can have a second retaining mechanism formed thereon. One of the first and second retaining mechanisms can comprise an extension portion and a first anti-rotation portion. The other retaining mechanism can comprise a receiving portion and a second anti-rotation portion. The articulating component can be advanced from an insertion position to an assembled position, such that the first and second mechanisms cooperatively interlock to inhibit translation and rotation of the articulating component relative to the C-shaped body portion of the stem structure.
PROSTHESIS
The invention relates to a femoral component (2) of a knee prosthesis. The component comprises a curved outer surface (4) for bearing against a tibial component. Said curved outer surface includes a posterior end and an anterior end. The curved outer surface includes an area (A) which extends from a first position closer to the posterior end to a second position closer to the anterior end, wherein said area (A) includes no parting line.
