Abstract

In this new open surgical instrument design, the surgiclip delivery mechanism is improved if compared with conventional surgical instruments. The surgiclips are moving to the front jaw pair through distal move of surgiclip pusher which can be manipulated by instrument handles. When doctors and surgeons move instrument handles together, the surgiclip will be driven forward and completely formed after surgiclip pusher distally drives surgiclip into the guiding groove in the front jaw pair. When doctors and surgeons free the instrument handles, the surgiclip pusher automatically moves back to original location or starting position to catch next surgiclip for next firing cycle. Since the advancing process of this surgiclip can be easily and reliably manipulated in the new design, the highly required dimensional tolerance control will be not necessary in making the instrumental components during production process. This improvement can prevent the surgiclips from drop-off, simplify the machining process, raise the production rate, and reduce the manufacturing cost (Figs. 10.1 and 10.2).
