Abstract: The invention relates to a device for connecting body tissues with a head part, which has a longitudinal axis and can be pushed into a body opening, wherein a plurality of tissue staples are accommodated in the head part in a storage position which tissue staples consist of a linear main section and two engagement sections projecting perpendicularly therefrom and are each aligned in a first plane which is substantially perpendicular to the longitudinal axis. Optimal usability in the human body is achieved in that a hydraulic cylinder and/or a cylinder rod are at least partially arranged in the interior of the space which lies between the engagement sections of the tissue staples in the storage position, and preferably that the cylinder rod is firmly connected to a slider.

Abstract: The invention relates to a device (100) for a medical instrument for applying a surgical suture, comprising a release unit (200) and an operating unit (300), said operating unit (300) comprising two pivotable gripper jaws (310, 320), each gripper jaw (310, 320) having a needle receptacle (340) and a needle fixation arrangement, said release unit (200) being configured to move the two gripper jaws (310, 320), and the trigger unit (200) also being configured to actuate said needle fixation arrangement.

Abstract: A device for connecting body tissues has a head part, which can be pushed into a body opening and has a longitudinal axis, wherein tissue staples are accommodated in the head part in a storage position. The tissue staples have a linear main section and two engagement sections projecting perpendicularly therefrom aligned in a first plane perpendicular to the longitudinal axis. Optimal usability in the human body is achieved by rotor elements, which are pivotable about an axis parallel to the main sections of the tissue staples with each have a bearing surface for an engagement section of a tissue staple to rotate said tissue staple from the storage position into a working position in which the tissue staple is arranged in a further plane oriented perpendicularly to the first plane, and in that a slider is provided to advance the tissue staple and deform it into a clamping position.
