Palpation Table - Towel Clamps.
O-ring screws are placed 66 cm apart to accommodate six reproductive tracts along the front of the table. Towel clamps are connected to the O-rings with rubber bands. The (Jones) towel clamps are attached to the mesovarium near the ovarian bursa to suspend the tract and to give it flexibility during the practice of retraction.
