Abstract: An undercutting tool for machining an undercut anchoring cut-out into a material, in particular a bone material, has a drive element, which is driveable in rotation about a main axis for application of a driving torque, and a rotatably mounted tool carrier, which has a working end with a working tool and is connectable to the drive element by means of a drive connection. The tool carrier is pivotable from an initial position, in which it extends along the main axis, into an undercutting position, in which it has an angle of inclination relative to the main axis and can be driven with a wobbling movement.

Abstract: An implanting device for positioning an object under a patient's skin includes a housing, a displaceable cannula holder, a cannula for receiving the object to be implanted and a tappet, which can be fixed relative to the housing. The cannula is displaceable from a first piercing position into a first operating position in order to deposit a first object, and the cannula is displaceable jointly with the tappet into a second piercing position and into a second operating position in order to deposit a second object. In order to move into the second piercing position, the cannula holder can be fixed to a first housing part, which is fixedly connected to the distal end of the tappet and is held displaceably on a second housing part forming the housing outlet.

Abstract: An anchor for surgical repair of a tissue, which anchor, for its placement on the tissue to be repaired, is movable along a hollow needle and connectable to a suture element, and it has at least two anchor portions displaceable relative to each other and connected to each other by an axle arrangement, via which the anchor portions are pivotable relative to each other between a retracted position and a deployed position. Provision is made that the axle arrangement has an axle element provided on the first anchor portion and a guide recess provided on the second anchor portion, by which the first anchor portion is held rotatably and linearly displaceably relative to the second anchor portion, and the anchor portions are displaceable from the retracted position to the deployed position by a rotation movement and are displaceable from said deployed position to a rotationally blocked end position by a linear movement.

Abstract: An injection device has a housing, in which a syringe can be held, which has an injection needle, a holding chamber, a plunger tip, and a syringe plunger; and a control assembly for the controlled actuation of the syringe during an application process, which includes at least an insertion stroke, an injection stroke, and a return stroke. The control assembly has an actuation element for receiving a manual driving force, a syringe holder, which can be slid in relation to the housing and to which the holding chamber can be fastened, a plunger holder, which can be slid in relation to the housing and to which the syringe plunger can be fastened, and a transmission device, which has a gearing for coupling the plunger holder to the actuation element, by means of which gearing the plunger holder can be driven in accordance with a motion of the actuation element relative to the housing.

Abstract: An injection device including a carrier housing in which an injection unit having at least one injection liquid container that can be pressed out can be inserted, and an actuating device which can be driven along an injection direction (R) to activate the injection unit. The actuating device includes a piercing carriage a receptacle for the injection unit, and an injection carriage which can be displaced relative to the piercing carriage. The injection carriage has an actuating plunger for acting on a plunger of the injection unit. The piercing carriage and the injection carriage can be actuated by a force application means at least in order to carry out a piercing stroke and an injection stroke, and a piercing depth (tE) of the injection unit can be set. For this purpose, the receptacle is mounted on the piercing carriage adjustably in the injection direction (R).

Abstract: The invention relates to an injection device (2) comprising a carrier housing (4), in which an injection unit (8) having at least one injection liquid container (10) that can be pressed out can be inserted, and an actuating device (12), which can be driven along an injection direction (R) to activate the injection unit (8), wherein said actuating device comprises a piercing carriage (14), a receptacle (18) for the injection unit (8) and an injection carriage (16), which can be displaced relative to the piercing carriage (14), said injection carriage having an actuating plunger (48) for acting on a plunger (50) of the injection unit (8), wherein the piercing carriage (14) and the injection carriage (16) can be actuated by a force application means at least in order to carry out a piercing stroke and an injection stroke, and a piercing depth (tE) of the injection unit (8) can be set. For this purpose, the receptacle (18) is mounted on the piercing carriage (14) adjustably in the injection direction (R).
