摘要： A delimited portion of suture material is immersed into a freezing media, such as liquid nitrogen, until the delimited portion is frozen. The frozen delimited portion is cut to provide a stiffened, non-brooming suture tip suitable for insertion into a needle bore. The cut, frozen suture tip is inserted into a needle and the needle is crimped to attach the suture to the needle. After attachment, the frozen suture tip returns to ambient temperature, reversing the effects of freezing the suture portion so that the suture adjacent the needle is as flexible as the remainder of the suture.

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 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.

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： A pair of dies 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 first needle. Each die has a pair of extensions spaced apart from each other and defines a generally circular crimping surface portion corresponding in dimension and configuration to the generally cylindrical outer surface portion of the needle. The space defines a unique relief zone between the pair of extensions of the die and is of configuration and dimension sufficient such that when the suture is positioned within the aperture of the needle and the dies are respectively positioned about the corresponding portion of the needle, the application of impact force to the dies will cause crimping of the needle with respect to the suture so as to attach the suture and the needle while portions of material forming part of the needle adjacent the stricken area are permitted to be deformed and to collect within the relief zones defined between the pairs of arcuate surface portions. Generally arcuate die overlap portions may be optionally provided on each die. A method of attaching a surgical needle to a suture is also disclosed.
