Abstract
The present invention relates to an apparatus for attaching surgical sutures to eyeless surgical needles. The apparatus includes a system for automatically presenting the surgical needles to a frame which positions and maintains the needle for subsequent swaging and a rotating die system which selectively impacts the needle to secure the suture thereto.
Claims14
Apparatus for feeding surgical needles to a suture crimping apparatus, which comprises:
- a container for receiving curved surgical needles and orientating the surgical needles in a predefined position for subsequent processing;
- a transmission member for receiving the orientated needles from said container at a receiving position and transferring the needles to a presenting position;
- means for transferring the needles between said presenting position and a crimping position, said transferring means including:
- means for grasping needles in said presenting position and for transferring said grasped needle to a needle pusher track;
- and
- means for moving the needle along said pusher track to said crimping position.
Apparatus for feeding surgical needles to a suture crimping apparatus, which comprises:
- a container for receiving curved surgical needles and orientating the surgical needles in a predefined position for subsequent processing, said container including a vibratory bowl having at least one sweep positioned on a bottom portion of said bowl and at least one ramp which transfers the needles from said bottom portion of the bowl to a receiving position, said receiving position being located at a side wall portion of said bowl, said vibratory bowl being coated with polyurethane;
- a transmission member for receiving the orientated needles from said container at said receiving position and transferring the needles to a presenting position;
- and
- means for transferring the needles between said presenting position and a crimping position.
Apparatus for feeding surgical needles to a suture crimping apparatus, which comprises:
- a container for receiving curved surgical needles and orientating the surgical needles in a predefined position for subsequent processing;
- a transmission member for receiving the orientated needles from said container at a receiving position and transferring the needles to a presenting position, said transmission member including a vibratory rail having a substantially cylindrical shape and which is adapted to support and transfer the needles to said present position, said rail having a radius equal to or less than the radius of curvature of the curved surgical needle;
- and
- means for transferring the needles between said presenting position and a crimping position.
Apparatus for receiving and orienting curved surgical needles, which comprises a container having a base, at least one side wall and a needle receiving member positioned on said base, said container having at least one sweep positioned on said base for orienting curved surgical needles to a predetermined orientation and at least one ramp for processing the curved surgical needles from said base to a needle presenting position on said side wall, said container being coated with a polymer whereby damage to points of the needles is substantially avoided.
Apparatus for feeding surgical needles to a suture crimping apparatus while minimizing needle point damage, which comprises:
- a container for receiving curved surgical needles and orientating the surgical needles in a predefined position for subsequent processing whereby damage to needle points is substantially avoided;
- a transmission member for receiving the orientated needles from said container at a receiving position and transferring the needles to a presenting position whereby damage to said needle points is substantially avoided;
- a drive member adapted for movement between said presenting position and a crimping position;
- a pair of jaws secured to said drive member and movable between an open position and a closed position to grasp and transfer a needle to a needle pusher track;
- and
- a pusher unit to move the needles along said needle pusher track whereby damage to said needle points is substantially avoided.
Apparatus for feeding surgical needles to a needle crimping apparatus while minimizing needle point damage, which comprises:
- a container configured to receive curved surgical needles, said container having a sweep member disposed within said container and configured to orient the surgical needles in a predefined position for subsequent processing;
- a transmission member operatively associated with said container, said transmission member receiving the orientated needles from said container at a receiving position and transferring the needles to a presenting position;
- a drive member mounted for movement between said presenting position and a crimping position;
- a pair of jaws secured to said drive member and movable between an open position and a closed position to grasp and transfer a needle from said presenting position to a needle pusher track;
- and
- a pusher unit operatively associated with said needle pusher track to move the needles along said needle pusher track to said crimping position, whereby damage to said needle points is substantially avoided as said needles are moved to said crimping position.
