摘要： An apparatus for thermally treating a plurality of curved suture needles. The apparatus includes a conveyer for transferring the plurality of curved suture needles from a source of curved suture needles to a receiver, a housing positioned adjacent the conveyer, the housing having a first end, a second end, and an opening running from the first end to the second end, the opening aligned with the conveyer to enable the plurality of curved suture needles to pass therethrough, and a heat source located within the housing for heating the plurality of curved suture needles as the plurality of curved suture needles are transferred by the conveyer from the first end of the housing to the second end of the housing. Also provided is a process for thermally treating a plurality of curved suture needles to enhance the stiffness and yield moment of the curved suture needles. The curved suture needles so treated have a desirable combination of stiffness, strength and ductility.

摘要： A method of thermal forming of refractory alloy suture needles is disclosed. Needle blanks made from refractory alloys are used to form surgical needles, which are heated to a temperature above the ductile to brittle transition temperature but below the recrystallization temperature of the refractory alloy. The heated needle blanks are then mechanically formed into a surgical needle.

摘要： Methods and systems for packaging surgical needles. In this system, a plurality of packages are indexed, by means of a package carrier, through a plurality of work stations, at which various operations are performed on the packages. In particular, at each work station, an operating device is moved from a home position to an operating position to perform an operation on the package: and after finishing the operation, the operating device is returned to the home positions. With all of the operating devices in their respective home positions, the package carrier can then be moved to index the packages forward. Each of the work stations generates a respective return home signal when the operating device of the work station returns to its home position. A determination is made as to whether return home signals have been generated indicating that all of the operating devices have returned to their respective home position; and, if such return home signals have all been generated, the package carrier is moved to move each package thereon to another one of the work stations.

摘要： An apparatus for cutting an indefinite length suture strand to uniform lengths for subsequent threading and swaging to a surgical needle includes a drawing tower having at least one guide member defining a drawing axis parallel thereto. First and second gripping devices are provided to grip the indefinite length suture strand and draw it along the drawing axis; each gripping device mounted for reciprocal movement on at least one guide member. A retractable cutter for cutting the indefinite length suture strand is also provided for cutting the strand at a start position along the drawing axis. The indefinite length suture strand is fed to the drawing axis and drawn a predetermined distance beyond the location of the retractable cutter for positioning within a suture receiving opening formed in the surgical needle, while the second gripping device reciprocates to a start position along the drawing axis. The indefinite length suture strand is then inserted within the suture receiving opening of the needle and cut to a predetermined length by the retractable cutter after the second gripping means has gripped the indefinite length suture strand at the start position.

摘要： An automated machine for attaching a suture to a surgical needle comprises a first apparatus located at a first predetermined location for sorting a plurality of randomly oriented needles and orienting each needle for automatic handling at a first predetermined location, each of the needles having a suture receiving opening formed therein. A second apparatus located at a second predetermined location is provided for automatically cutting an indefinite length of suture material to a definite length suture strand and for automatically inserting an end of the definite length suture strand into the suture receiving opening formed in the needle. Also provided is a third apparatus for swaging the needle to close the suture receiving opening about the suture to secure said suture thereto and form therefrom a needle and suture assembly. An indexing device automatically receives each individual needle in a predetermined orientation at the first predetermined location and conveys the needle for sequential processing from the first to the second locations to form the needle-suture assembly.
