A new modification of obstetric tongs

详细

Since the invention of obstetric forceps by Chamberlen and Palfyn, this instrument has undergone numerous modifications. Due to the different arrangement of the individual parts of the instrument and their various combinations, the number of varieties has increased greatly and reached 300 too. However, this diversity is only apparent. Leaving aside the various details of the device and secondary features that are not of great importance for the essence of the heart, we half-mean only a few types of forceps, differing mainly in the curvature of the spoons, in the structure of the lock, in the mutual relation of the two (intersecting and parallel). Each of these types has its own advantages.
