A device and method are provided for clips or staples as an effective substitute for suture material when joining body tissue or covering body tissue with a mesh, such as is particularly used in fracture operations. The device for applying a medical lockable clip (1) in a tissue area, includes a) an automatic advancing mechanism oriented in the direction of the tissue area from a starting position and having a guide in the advancing direction for the clip, wherein the clip has two gripper teeth oriented in the advancing direction, b) a stop for the advancing mechanism, and c) a locking element displaceable with the advancing mechanism and having a locking mechanism on the clip side for locking the clip, wherein d) the locking element is displaceable together with and parallel to the advancing mechanism, and e) the stop does not limit the motion of the locking element.

1. A device for the application of a medical lockable clip in a tissue area, the device comprising: an automatic feed mechanism, which can be moved from a starting position in the direction of the tissue area, with a guide in a feed direction for the clip;a stop for the automatic feed mechanism;a locking element, which can be moved with the automatic feed mechanism; anda locking mechanism, wherein:the locking element is set into motion together with and in parallel to the automatic feed mechanism;the automatic feed mechanism is formed by a shoot-in cylinder with a shoot-in piston and the locking element is formed by a closing cylinder with a closing piston;the shoot-in cylinder and the closing cylinder are connected via a T-shaped distributor and a pressure line wherein a reducer is arranged in the pressure line leading to the closing cylinder; andthe stop does not limit the motion of the locking element. 2. The device in accordance with claim 1, wherein the guide has a positive-locking and/or frictionally engaged mount for the clip. 3. The device in accordance with claim 1, wherein the locking mechanism has a toggle lever element. 4. The device in accordance with claim 1, further comprising a triggering mechanism comprising a triggering valve, an auxiliary cylinder and an opening valve. 5. The device in accordance with claim 4, wherein an air supply to the automatic feed mechanism can be pneumatically released by means of the triggering valve, the auxiliary cylinder and the opening valve only after a preset opening pressure has been reached. 6. The device in accordance with claim 4, wherein said triggering valve and said opening valve have vent holes to release pressure in pressure lines of the triggering valve and the opening valve. 7. The device in accordance with claim 1, further comprising a restoring means for moving the automatic feed mechanism and the locking element into their respective starting position. 8. The device in accordance with claim 7, wherein the restoring means comprises pneumatic restoring pistons. 9. The device in accordance with claim 7, further comprising a spring arranged between the automatic feed mechanism and the locking element and acting on the latter. 10. The device in accordance with claim 1, wherein the closing cylinder, within which the closing piston guides, runs in a cylinder liner. 11. The device in accordance with claim 1, further comprising a clip magazine with a serial clip feed in the starting position. 12. The device in accordance with claim 1, wherein the automatic feed mechanism is a pneumatic or hydraulic feed mechanism. 13. A device for the application of a medical lockable clip in a tissue area, the device comprising: an automatic feed mechanism, which can be moved from a starting position in the direction of the tissue area, with a guide in the feed direction for the clip;a stop for the automatic feed mechanism;a locking element, which can be moved with the automatic feed mechanism;a triggering mechanism comprising a triggering valve, an auxiliary cylinder and an opening valve; anda locking mechanism, wherein:the locking element is set into motion together with and in parallel to the automatic feed mechanism;said triggering valve and said opening valve have vent holes to release a pressure in pressure lines of said triggering valve and said opening valve; andthe stop does not limit the motion of the locking element. 14. A system, comprising: a device for the application of a medical lockable clip having two gripping teeth directed in a feed direction in a tissue area, the device comprising:an automatic feed mechanism, which can be moved from a starting position in the direction of the tissue area, with a guide in a feed direction for the clip;a stop for the automatic feed mechanism;a locking element, which can be moved with the automatic feed mechanism; anda locking mechanism, wherein:the locking element is set into motion together with and in parallel to the automatic feed mechanism;the automatic feed mechanism is formed by a shoot-in cylinder with a shoot-in piston and the locking element is formed by a closing cylinder with a closing piston;the shoot-in cylinder and the closing cylinder are connected via a T-shaped distributor and a pressure line wherein a reducer is arranged in the pressure line leading to the closing cylinder; andthe stop does not limit the motion of the locking element.
