摘要:
The invention relates an injection device (2) having a housing (4), in which a syringe (16) can be held, which has an injection needle (18), a holding chamber (20), a plunger tip (22), and a syringe plunger (24); and having a control assembly (26) for the controlled actuation of the syringe (16) during an application process, which comprises at least an insertion stroke, an injection stroke, and a return stroke, wherein the control assembly (16) has an actuation element (28) for receiving a manual driving force (mF), a syringe holder (12), which can be slid in relation to the housing (4) and to which the holding chamber (20) can be fastened, a plunger holder (14), which can be slid in relation to the housing (4) and to which the syringe plunger (24) can be fastened, and a transmission device (30), which has a gearing (32) for coupling the plunger holder (14) to the actuation element (28), by means of which gearing the plunger holder (14) can be driven in accordance with a motion of the actuation element (28) relative to the housing (4). According to the invention, the housing (4) has a first outer housing part (6) and a second outer housing part (8), which are retained on each other in such a way that said housing parts can be moved between an open position, in which the syringe holder (12) is accessible, and a closed position, in which the syringe holder (12) is enclosed.

The invention relates to an anchor arrangement (2) for surgical tissue repair, such as in particular for repair of a meniscus tear (R), having at least one first anchor (4) and one second anchor (6), which are movable along a hollow needle (14) for placement on a tissue to be repaired (G) and connected to each other via a seam element (8). According to the invention, the first anchor (4) and the second anchor (6) each extend between a distal end (22) and a proximal end (24) and form a guide surface (26) on the outside thereof for contacting an inside (28) of a hollow needle (14) at least in part. In addition, there are deflection means (38) on the anchors (4, 6), via which a torque (MD) can be applied at least in part to the anchors (4, 6) during or after setting. According to the invention, at least one of the anchors (4, 6) has at least two anchor sections (50, 52), 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 (26) spans a cross-section (Q) deviating from a circular profile, and an unfolded position.
