Patent ID: 7785335

Claim:
A device for clamping off organic tissue, comprising: a tissue clamp that can be released from a distal end of an application instrument, said clamp having proximal and distal clamping bars made of absorbable material; an application crosspiece having an internal pushing device and a guide groove for receiving the distal and proximal clamping bars, the proximal clamping bar being displaceable in the guide groove by said internal pushing device, while the distal clamping bar maintains its position until the organic tissue has been clamped off, the application crosspiece having holders for accommodating the clamping bars; wherein the proximal clamping bar has at least one guide pin on each side of its base, and the distal clamping bar has at least one guide pin on each side of its base or has a fixation shoulder, and wherein the guide pins on the proximal clamping bar and the guide pins or shoulder on the distal clamping bar are configured to fit into crosswise grooves in the application crosspiece, so that the clamping bars are inserted into said crosswise grooves perpendicular to an axis of the application crosspiece; wherein the proximal clamping bar is displaced in the guide groove of the application crosspiece and in longitudinal grooves formed on both sides of the crosspiece on an inside of the crosspiece, with the guide pins; wherein the proximal clamping bar has a holder pin on its base, disposed in a direction of the distal end, which holder pin engages into a corresponding holder bore of the distal clamping bar when the proximal clamping bar is displaced by the internal pushing device, and produces a force-fit and shape-fit connection with this holder bore, while simultaneously clamping off the organic tissue; and wherein if the distal and proximal clamping bars have guide pins, the guide pins are constructed so that they shear off if an expenditure of force required to clamp off the organic tissue is exceeded, and wherein if the distal clamping bar has a fixation shoulder, the fixation shoulder has such an elasticity that the clamping bars, with the organic tissue clamped off between them, as a tissue clamp, can be released from the application crosspiece by means of the pushing device, in a direction of the distal end.
