【Instructions for Use】
1)Select appropriate staplers through conventional measuring method. The patient shall lie down horizontally and be operated with local anaesthesia, sacrum anaesthesia or other effective ways of aneasthesia;
2)For patients with prepuce adhesion, the adhesion shall be firstly peeled off and for patients with phimosis, the preputial orifice can be out (Note: the cutting shall not exceed the suture part in order not to affect suture) so as to put in the glans penis cover;
3)Screw out the adjusting nut and taken out the glans penis cover from the instrument (When they are tightly fixed, we can use the adjusting nut to gently push forward the glans penis cover.) Use common instruments such as hemostatic forcep to lift the prepuce and cover it on the surface of glans penis cover; after tensioning the inner plate, adjust the outer plate to the cut position; fix the prepuce onto the rod using ribbons or common suture and pay special attention to ensure the length of frenum. In case of patients with too long prepuce or children, the prepuce outside the ribbon or suture in order to cover the instrument. Before covering the instrument, gently take off the cover of nail cartridge in order to prevent suturing nails from dropping. Do not move the finger pushing the frenum during the operation. Insert the link rod to the central hole of the instrument to the end and gently screw the instrument with the right hand to ensure that the relatively thick blood vessel avoids the cutting groove at the head end of the instrument (This is the clearance between two suturing nails.) Hold the instrument with the left hand and mount the adjusting nut with right hand and screw it to the right position. When the tail end face of the rod is at the same level as the metal inserts of adjusting nut, it means the adjusting nut has been adjusted to the right position (In case the tissue of the patient is too thin or the patient is a child, the end face of the rod can be slightly protruded; otherwise, the end face of the rod can be slightly lower than that of metal insert.) (Note: when screwing out the adjusting nut, the action shall not be too fierce and try best to keep no rotation of glans penis to prevent tearing of the sutured position.).
4)Remove the safety clip; forcibly press the handle and when you hear a sound of “Bang” or feel obvious breakthrough, the trigger is at the right position. Hold if for about another 8~10s (In order to prevent capillary hemorrhage, the operated part can be wrapped with dry gauze.). And then release and screw out the adjusting nut. If the reset spring dose not reset after the hand is off, reset can be done by slightly pushing the handle outward. When the adjusting nut is screwed out for about 5mm, forward slightly to cut the suture position and observe whether it is completely cut off. In case some tissues are not completely separated, trim cut can be done to it. After the stapler is removed, immediately wrap up the operation part with dry gauze and press it for 3~5mins to prevent capillary hemorrhage at the wound or hemaoma after operation. If the pressing effect at the wound is not so good, local suture can be done. Wrap it up with dry gauze (or oil gauze when necessary) and appropriately bind it up with pressure bandage. Provided that impact is imposed to the patients’ urinating after operation, the patient shall be told to loosen the outer layer of the bandage and bind it well after urinating. In case no capillary hemorrhage happens two days after operation, the outer layer can be removed.

After operation, the suturing nails may be not easy to fell off or hematoma and edema may happen.
