Abstract: الإختراع هو جهاز يستعمل في "عملية قطع الإرتفاقsymphysis " باستخدامه في فصل مفصل الإرتفاق العاني من ناحيته الخلفية، وهي عملية جراحية يطلق عليها طبيا "بضع الإرتفاق"، وتعتبر عملية منقذة لحياة الطفل أثناء الولادة وأيضا لوالدته حينما يكون حوض الأم ضيقا يعوق الولادة الطبيعية في ضوء القرار الطبي بإجراء هذه العملية، وباتباع التعليمات يُمكّن الجهاز الأطباء والقابلات من إجراء عملية بضع الإرتفاق متى تدربوا عليها. يتكون الجهاز من ثلاثة أجزاء: قنية ) cannula ( طولها 14سم وبمحيط مناسب مصنوعة من الصلب الغير قابل للصدأ ولها شطبة حادة أمامية ونصفها الخلفي سميك ليسنى إحكام قبضة اليد عليه أثناء الإستعمال. مردود ) stylet ( طوله 14سم مصنوع من الصلب الغير قابل للصدأ ليحتل مكانه بإحكام داخل القنية فيمنع إنسداد تجويف القنية بالأنسجة أثناء دفعها داخل الجسم وله نهاية رأسية تمنع تقدمه خارج شطفة القنية عند إدخاله في تجويفها. القاطع: وطوله 14سم مصنوع من الصلب الغير قابل للصدأ يحل مكان المردود بعد التقدم داخل الجسم وتتكون مقدمته من جانبها العلوي بطول 7ملليمتر من حافة حادة تعمل كمشرط لقطع الأربطة والغضروف من خلف مف
