摘要:
A machine and process for packaging armed sutures into tray packages. The machine has a frame with a rotatable indexing disc member mounted to the top of frame. A plurality of tool nests are rotatably mounted to the top of the indexing disc. Tray packages mounted in the tool nests are rotated to wind sutures into a suture channel in the packages. A stylus having a front nose member and a rear heel member guides suture into the suture channel.
摘要:
A package for sutures having a winding channel. The package has a base member and a cover member that is mounted to the base member. A plurality of cantilieverd doors cover the winding channel.
摘要:
A suture package having a base, an upwardly extending wall, an inner dispensing wall, a suture channel between the walls, and a top friction plate member mounted therein. The package has a central needle park and a discharge opening in the friction plate for removing a needle and suture from the package.
摘要:
A suture winder machine and, more particularly, a semi-automated suture winding station of the machine adapted to facilitate the high-speed winding of multiple sutures, which are each attached to needles, into a peripheral channel of a tray utilized for packaging the needles and attached sutures. A substantially flat suture tray loaded with multiple needles and sutures extending therefrom is mounted on a rotatable platform incorporating registration structure for ensuring the appropriate mounting and positioning of the suture tray thereon, and with the winding machine containing operative structure adapted to rotate the suture tray about an axis perpendicular to the planar surface thereof so as to enable the extending multiple sutures to be bundled and wound for depositing in a channel formed along the periphery of the suture tray. The winding station of the machine includes cam-controlled stylus and suture guide structure; with the stylus engaging successive resilient fingers on the tray covering the channel during rotation of the tray on the platform on which the package is supported for rotation, so as to in cooperation with the suture guide, cause the sutures to be continually introduced into the channel beneath the raised fingers. Also disclosed is a cover-applying apparatus for attaching covers to the trays and concurrently forming product-labeling structure fastened to the trays.
摘要:
An automated machine for attaching a suture to a surgical needle having a suture receiving opening formed therein, and for packaging the same in a package tray comprises a first workstation including a device for sorting a plurality of needles and orienting each needle for automatic feeding to a second swaging workstation, a second workstation including a device for automatically cutting an indefinite length of suture material to a definite length and a device for automatically swaging the needle to close the suture receiving opening about a free end of the suture to secure the suture thereto and form a needle-suture assembly, a needle packaging station including a device for sequentially receiving at least one of the needle-suture assemblies in a package tray in synchronism with the second workstation, the needle packaging station having a device for automatically winding the depending suture portion of the needle-suture assembly into the package tray, a first indexing device for sequentially receiving individual oriented needles fed from the first workstation and transferring each of the needles from the first workstation to the second workstation to form the needle-suture assembly thereat, the first indexing device sequentially indexing the needle-suture assemblies from the second workstation to the needle packaging station.

摘要:
A one piece needle and suture holder is described in which a rounded channel is formed for retention of the suture. One end of the suture exits the channel toward the interior of the channel and is attached to a needle located in a needle holder in the interior of the channel. The channel is formed with an open side, to which are attached a plurality of hinged doors. After the suture is wound in the open channel, the doors are folded over the open side of the channel and are locked in place to retain the suture within the channel. In an alternative embodiment a paper cover is utilized to complete the enclosing channel. To afford ease of winding the suture the bottom of the channel is perforated for the application of a vacuum to the channel during suture winding. Also disclosed is a needle park for retaining the needle in the center of the package. In a preferred embodiment the needle park is backed by a relief flap to enable the needle to be conveniently grasped by a forceps during removal of the needle and suture.
