stranding systems for fixation of surgical needles to sutures having resistance test in suture fixation press

摘要

the present invention relates to a stranding system for fixing surgical needles to sutures and testing the fixation strength that includes a frame, a frame-mounted bottom frame matrix, and a frame-top frame template and being movable up and down along a geometry axis which is aligned with the background geometry matrix. the bottom splicing matrix includes a hinge mechanism with a bottom plate mounted on the frame and a top plate overlapping the bottom plate. the top and bottom plates are pivotally connected to allow the top plate to rotate in relation to the bottom plate. the bottom jamming matrix includes a jamming tool that extends towards the top jamming matrix along the jamming axis, and a load cell disposed between the top and bottom plates to monitor the load. the system includes a control system having one or more tensile test programs stored in it to assess tensile tests on armed surgical needles to determine whether armed surgical needles are acceptable or unacceptable.
