Abstract: 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.

Abstract: The invention relates to a screw (1), preferably a bone screw, comprising a shaft (2) with a tip (3), a head (4) and a thread (5). The shaft further comprises a longitudinal axis (A). An array of radial cross-sectional surfaces (Q) of the head (4) extend through the longitudinal axis (A) of the screw (1), the location of each radial cross-sectional surface (Q) being defined by an azimuth angle (6) in a plane (E) perpendicular to the longitudinal axis (A). Each radial cross-sectional area (Q) has an area defined by the longitudinal axis (A) and the outer surface of the screw (8). The thread (5) extends into the head (4) in such a way that the surface areas of the radial cross-sectional surfaces (Q?) in a first azimuth angle range (9) are constant and the surface areas of the radial cross-sectional surfaces (Q?) in a second azimuth angle range (10), which is different from the first, have a different, preferably smaller, value than the surface areas in the first azimuth angle range (9).

Abstract: The invention relates to an implant (1) for the treatment of bone, in particular for covering defects or drill holes or for the reconstruction of bone defects or malformations. This comprises at least one frame structure (2) and at least one adaptation area (3). The edge of the implant (4) is thereby partially, but not continuously, formed by the frame structures (2), which are located outside the adaptation area (3).

Abstract: Snoring and sleep apnea are conditions associated with a narrowing of the airway. A device (10) and a method for piercing a soft tissue channel in the pharynx and an implant for insertion into this soft tissue channel are disclosed, with which these symptoms can be treated. The device according to the invention comprises a handle (12) and a blade (11) with a tip (16), which are connected to each other via an interface (13). In this process, a channel is pierced through the device (10), the shape of which is designed in connection with the shape of the implant in such a way that the narrowing of the airways is optimally treated.

Abstract: 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.

Abstract: 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.
