Patent number: 11839409Abstract: A bone plate for reconstruction or trauma treatment of a bone which comprises first and second ends, a first contact surface for contacting and securing on a first region of the bone, and a plurality of receiving mechanism each having at least one opening for receiving at least one securing element. At least two adjacent wings extend at least from the first end of the main section, each has a second contact surface for contacting and securing to a second region of the bone, as well as at least one receiving mechanism having at least one opening for each receiving a securing element. A minimum bending stiffness of the main section, in relation to an axis (x) running perpendicular to the first contact surface, is greater than the minimum bending stiffnesses of the wings, but smaller than the total minimum bending stiffness of all wings extending from the first end.Type: GrantFiled: October 9, 2020Date of Patent: December 12, 2023Assignee: MEDARTIS HOLDING AGInventors: Dirk Thiel, Andreas Mullis, Jürgen Schonhardt, Hermann Zeuner, Simon Martin Schätzle

Patent number: 11660130Abstract: A wrist arthrodesis plate (20) consisting of a distal region (21) and of a proximal region (22) which adjoins the distal region (21) in the direction of a longitudinal axis (A). The plate (20) is of such a shape and size that the distal region (21) of the plate can be fastened to the carpus (1) and a proximal region (22) of the plate can be fastened to the radius (3) by fastening devices, such as screws, which can be inserted into plate holes. A distal end region (29), which comprises a farthest distal location (23) of the plate (20), is of a shape and size that the distal end region (29) can be placed with the farthest distal location (23) exactly, and only, on a carpal bone from the group comprising trapezium (11), trapezoid (10), capitate (9) and hamate (8), without covering any part of the laterally adjacent bones.Type: GrantFiled: February 6, 2019Date of Patent: May 30, 2023Assignee: Medartis Holding AGInventors: Daniel Ebi, Radek Kebrle, Marc Ammann, Daniel Kainz, Simon Martin Schätzle, Thomas Tribelhorn

Patent number: 10751100Abstract: A bone screw comprising a first end having an engagement contour for engaging with a tool to facilitate insertion or removal of the bone screw, and a blocking element is arranged at a second end thereof. The blocking element is provided with a circumferential outside surface which comprises at least one clamping surface which—when viewed in an azimuth plane perpendicular to a longitudinal axis of the bone screw—widens outwardly in a wedge-shaped manner away from the longitudinal axis. The bone plate includes at least one opening which is at least partially delimited by an inside wall having an inner contour for receiving and fixing the blocking element of the bone screw. At least one bone screw and at least one bone plate together form a surgical set.Type: GrantFiled: November 22, 2017Date of Patent: August 25, 2020Assignee: MEDARTIS HOLDING AGInventors: Dirk Thiel, Andreas Mullis, Juergen Schonhardt, Hermann Zeuner, Simon Martin Schaetzle

Patent number: 10756326Abstract: An electrical energy source for an electrically drivable tool containing: a main body, which extends along a longitudinal axis, having a first end and a second end lying opposite the first end with respect to the longitudinal axis; at least one first electrical terminal, which extends away from the first end and has a first diameter; and at least one second electrical terminal, which extends away from the second end and has a second diameter. A voltage is present between the first and second terminals. The first diameter is different from the second diameter. The first electrical terminal extends away from the first end, and the second electrical terminal extends away from the second end of the main body. A tool kit having at least one electrically drivable tool and having at least one electrical energy source and a method for inserting an energy source into an electrically drivable tool.Type: GrantFiled: May 20, 2015Date of Patent: August 25, 2020Assignee: MEDARTIS HOLDING AGInventors: Andreas Mullis, Hermann Zeuner, Jürgen Schonhardt, Micha Huber

Patent number: 10582959Abstract: A screw (1), in particular a bone screw, comprising a head (16), a shaft (2) and a point (15). The screw (1) has a recess (4) with a contour (5) on a head side (3), The screw (1) is provided with an insertion post (8) in the recess (4), which insertion post is connected to the screw (1) via a predetermined breaking point (7). After breaking the predetermined breaking point and separation of the insertion post (6) from the screw (12), a counter-contour (13) of a tool (12) can be brought into operative connection with the contour (5) of the recess (4). The predetermined breaking point (7) is arranged within the recess (4) such that, after removal of the insertion post (6), a transmission of torque is possible between the tool (12) and the screw (1) via the contour (5) and the counter-contour (13).Type: GrantFiled: August 3, 2015Date of Patent: March 10, 2020Assignee: MEDARTIS HOLDING AGInventors: Barry Langer, Peter Scheuble, Marc Ammann, Herbert Polzhofer

Patent number: 10561450Abstract: A bone plate (1) with at least one receiving opening (2) for a bone screw (3) with a screw head (4), wherein the receiving opening (2) has a compression area (5) with a compression contour (6) and a blocking area (7) with a blocking contour (8). The compression contour is designed such that rotation of the bone screw in its one screwing-in direction (E) causes lateral movement of the bone screw toward the blocking area (7). The compression contour (6) is designed as an engagement contour (6), such that lateral movement is generated by engagement between the engagement contour (6) and a mating contour (9) on the screw head or tool. A surgical kit containing at least one such bone plate (1) and at least one bone screw with a screw head (4), which bone screw is insertable into the receiving openings of the bone plate (1) is also disclosed.Type: GrantFiled: February 26, 2015Date of Patent: February 18, 2020Assignee: MEDARTIS HOLDING AGInventors: Dirk Thiel, Alexander Zuberer
