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： A method for producing a detachable surgical needle-suture combination of the type incorporating a fluid swellable suture material is capable of producing needle-suture attachments which conform to the prescribed minimum pull-out forces for detachable needle-suture combinations as set forth in the U.S. Pharmacopeia. Generally, the method includes the steps of providing a surgical needle and a fluid swellable suture, immersing an end portion of the suture into a liquid solution whereby the suture end portion swells and assumes an expanded condition, positioning the suture end portion in its expanded condition into an aperture formed in the blunt end of the needle and swaging the blunt end of the needle to cause deformation of at least a portion of the blunt end and engagement with the suture end portion to effect needle-suture attachment.
摘要翻译： 用于生产包括流体可溶胀缝合材料的类型的可拆卸外科缝合缝合组合的方法能够产生符合美国规定的可拆卸针缝合组合的规定的最小拉出力的针缝合附件 药典。 通常，该方法包括以下步骤：提供外科用针和流体可膨胀缝合线，将缝合线的端部浸入液体溶液中，由此缝合线端部膨胀并呈现膨胀状态，将缝线端部定位在其扩张状态 形成在针的钝端中形成的孔，并且锻造针的钝端以引起钝端的至少一部分的变形并且与缝合线端部接合以实现针缝线附接。

摘要： A method and apparatus for tipping, cutting, and sorting sutures includes a suture supply, a tipping station wherein delimited portions of the suture are tipped, preferably with a cyanoacrylate tipping agent, a diameter measuring station, a cutting station wherein a knife is operated to cut the suture at a tipped portion to form cut suture lengths having tipped suture ends for insertion into the barrel end aperture of a surgical needle, and a pair of graspers for alternatively grasping and drawing the suture from the suture supply through the tipping apparatus, the diameter measuring station and the cutting station. Optionally, a drying station can be interposed to hasten the curing of the tipping agent. Preferably, a controller is provided for controlling the sequence of operation of the apparatus and for controlling sorting of cut suture lengths deposited by the graspers onto a tilting sorting table.
