Doctor's bag

The doctor entered the detection room, leaving the husband standing outside the room. Two minutes later the doctor came out and asked for a knife! The husband apologized for not having them! The doctor entered the room again and came out after five minutes and asked this time for a hammer with a screwdriver! The husband went, and brought them quickly, and was in a state of fear and panic! The doctor entered the room again, but returned after five minutes saying: "I think I need a saw!"

then frightened husband replied "Can I take my wife to hospital if she is so serious?" "No, I'm just trying to open my bag," the doctor replied.
