Crimping device and method

A method of securing at least one suture to at least one double-pointed medical suture needle, comprising the steps of:

• threading the double-pointed medical suture needle by inserting the suture through a through-hole of the double-pointed medical suture needle;
• providing a crimping device having a lower block and an upper block, wherein the lower block comprises a lower crimping pin arranged in a lower crimping pin channel at an intercept of a first groove and a second groove and the upper block comprises an upper crimping pin arranged in an upper crimping pin channel at an intercept of the first groove and the second groove;
• placing the double-pointed medical suture needle in the second groove and the suture in the first groove;
• crimping the double-pointed medical suture needle by moving the lower block and the upper block together and pushing the lower crimping pin and the upper crimping pin against and deforming the double-pointed medical suture needle to secure the suture to the double-pointed medical suture needle;
• and
• pressing the lower block and the upper block against each other such that a lower spring between the lower block and a secondary lower block, to which the lower crimping pin or a lower set screw of the lower crimping pin is fixed, is compressed and the lower crimping pin protrudes from the lower block, and such that an upper spring between the upper block and a secondary upper block, to which the upper crimping pin or an upper set screw of the upper crimping pin is fixed, is compressed and the upper crimping pin protrudes from the upper block.

A crimping device for securing a suture to a double-pointed medical suture needle, the crimping device comprising:

• a lower block and an upper block that can be pressed towards each other to secure the suture to the double-pointed medical suture needle, the lower block comprising:
• a first groove configured to accommodate the suture;
• a second groove configured to accommodate the double-pointed medical suture needle, the first and second grooves arranged substantially perpendicularly to each other,
• wherein the lower block comprises a lower crimping pin arranged in a lower crimping pin channel at an intercept of the first groove and the second groove;
• wherein the upper block comprises an upper crimping pin arranged in an upper crimping pin channel at the intercept of the first groove and the second groove;
• wherein the lower crimping pin and the upper crimping pin are configured to be moved in the lower crimping pin channel and the upper crimping pin channel, respectively, towards the intercept of the first groove and second groove to secure the suture to the double-pointed medical suture needle,
• further comprising a secondary upper block arranged on an exterior side of the upper block relative to an interior side arranged towards the lower block, wherein the upper crimping pin is fixed to the secondary upper block.
