Abstract: An anchor arrangement is provided for surgical tissue repair, such as in particular for repair of a meniscus tear, having at least one first anchor and one second anchor, which are movable along a hollow needle for placement on a tissue to be repaired and connected to each other via a seam element. The first anchor and the second anchor each extend between a distal end and a proximal end and form a guide surface on the outside thereof for contacting an inside of a hollow needle at least in part. In addition, there are deflectors on the anchors, via which a torque can be applied at least in part to the anchors during or after setting. At least one of the anchors has at least two anchor sections, which are movable relative to each other and which can be pivoted relative to each other between a folded position, in which the guide surface spans a cross-section deviating from a circular profile, and an unfolded position.

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.
