Materials and Preparation
- Red felt fabric
- Beige felt fabric
- Sewing needles
- Black thread
- Cotton balls
- Black marker
- Red marker
- Long pink twisting balloons
- "Press and seal" plastic food wrap
- Collect all of the necessary materials and tools you need to complete the model.
- Print out the stencils and arrange the six pieces of paper with ABC in the top row and CDE in the bottom row (Figure 1). Tape them together and cut out the shapes. Use these stencils to trace and cut out the shapes on the felt fabric. With the red felt fabric you will need the uterus shape and two fallopian tubes and with the beige felt fabric you will need two ovary shapes and one bladder shape (Figure 2).
- Next, fold the uterus shape in half. Thread a needle with black thread and sew along the edges to close the sides of the uterus, keeping the bottom section open. Fill with stuffing (Figure 3).
- Fold one ovary shape in half. Using black thread, sew along the edge half-way. Before sewing it closed, stuff the ovary with one cotton ball (Figure 4). Then, finish sewing the edge completely. Do this with the other ovary shape as well (Figure 5).
- For the fallopian tube, take the fallopian shape and fold it in half. Sew along the edge and the bottom with black thread, keeping the jagged end open. Do this to the other fallopian tube shape as well (Figure 6).
- Color in the round ligaments with red marker to distinguish them from the bladder shape (Figure 7).
- For the uterine arteries, take 2 pieces of the long pink twisting balloons and fill each with enough water to fill them without expanding the balloon. Tie a knot at around half the full length of the balloon (or approximately 7 inches), then cut off the remaining end (Figure 8).
- Tear off one large sheet of the "press and seal" plastic food wrap. With the adhesive side of the plastic food wrap facing up, arrange the structures on top with the uterus in the center, the fallopian tubes and ovaries on each side of the uterus, the bladder shape on top of the lower end of the uterus, and the water-filled pink balloons as arteries on each side of the uterus (Figure 9).
- Then place a second sheet of the "press and seal" plastic food wrap over the structures. Press the sheets together to create a complete seal around each structure. Trim the plastic food wrap, leaving around a 3-4 inch border around the structures (Figure 10).
The CREOG Surgical Skills Task Force created this simulation as part of a standardized surgical skills curriculum for use in training residents in obstetrics and gynecology.
