The invention relates to an apparatus used in the separation of the Symphysis pubis joint from its posterior aspect. This process medically named as Symphysiotomy. The apparatus consists of 3 parts: (1). Size 14G cannula which is 14cm in length, made of stainless steel and has a sharp bevel and thickened posterior part to enable the user to have a good grip on it during usage. (2). A stylet 14cm long made of stainless steel to fit in the inside of the cannula to prevent coring of the tissues during the introduction of the cannula. It has a vertical end to stop the advancement inside the cannula. (3). A cutter which is 14cm long and made of stainless steel and fits inside the cannula when the stylet is removed. Its front part is sharp on one side to cut through the ligament and cartilage of the symphysis pubis from its posterior aspect. Its back has a half-circle end to prevent the cutter from advancing beyond the bevel of the cannula inside the tissues. This is a life-saving operation and used to widen the diameter of the pelvis during certain situations of obstructed delivery of the baby. The design of the apparatus and instructions of its use enable doctors and midwives to perform the symphysiotomy procedure once they are trained on its use. The use of the invention avoids bleeding, injury to urethra and bladder, and avoids the formation of skin scar. The symphysiotomy scalpel obtained patent status from the King Abdulaziz City for Science & Technology (5910 dated 20 May 2018).
