I had ilizarov apparatus[1] on my legs for over a year(once during age 7 and another during age 15) and my mom used to sterilise the instruments (Scissors, Forceps) used for dressing wounds at home(every alternate day) in pressure cooker(on advice of the doctor).
I presume, pressure cookers are still being used for the sterilisation of instruments[2] in several parts of the world as its still common than an electric cooker.
