摘要： An apparatus is disclosed for attaching a surgical needle having a generally cylindrical end portion defining an elongated aperture having a generally circular cross-section and a suture having a generally elongated end portion of generally circular cross-section corresponding in dimension to the elongated aperture of the needle. The apparatus includes a pair of dies, each having a die face with an inner die surface portion. The inner die surface portion includes at least one generally planar crimping surface having an arcuate recess formed therein which extends along at least a portion of the planar crimping surface. The arcuate recess defines a material relief zone such that when the end portion of the suture is positioned within the aperture of the needle and the dies are positioned about the generally cylindrical end portion of the needle with the crimping surfaces generally facing the outer surface thereof, the application of an inward crimping force to the dies causes the dies to impact the needle and produce inward crimping forces on opposed sides of the needle end portion to attach the needle to the suture. The relief zones defined by the arcuate recesses receive and collect deformed material from the needle. According to the invention, the symmetry of the needle is maintained and the attachment is predictable and superior to those of the prior art.

摘要： An apparatus is disclosed for attaching a surgical needle having a generally cylindrical end portion defining an elongated aperture having a generally circular cross-section and a suture having a generally elongated end portion of generally circular cross-section corresponding in dimension to the elongated aperture of the needle. The apparatus includes a pair of dies, each having a die face with an inner die surface portion. The inner die surface portion includes at least one generally planar crimping surface having an arcuate recess formed therein which extends along at least a portion of the planar crimping surface. The arcuate recess defines a material relief zone such that when the end portion of the suture is positioned within the aperture of the needle and the dies are positioned about the generally cylindrical end portion of the needle with the crimping surfaces generally facing the outer surface thereof, the application of an inward crimping force to the dies causes the dies to impact the needle and produce inward crimping forces on opposed sides of the needle end portion to attach the needle to the suture. The relief zones defined by the arcuate recesses receive and collect deformed material from the needle. According to the invention, the symmetry of the needle is maintained and the attachment is predictable and superior to those of the prior art. A surgical needle-suture combination having a controlled suture release is also disclosed as well as a method for forming such attachment is also disclosed.
