Fidelity notes and tissue selection
[edit | edit source]The simulator is composed of the target tissues:
- Part A - Uterus
- Part B - Ovaries
- Part C - Ectopic contents
Required tools and equipment
[edit | edit source]Tape, stapler, scissors and measuring tools (ruler, marker).
Required manufacturing processes and skills
[edit | edit source]N/A
Ectopic pregnancy fabrication instructions
[edit | edit source]Part A - Uterus
[edit | edit source]- Take one large sock, stuffing the toe with cotton material (Stuffing can be a matched sock, fabric or lap pad based on availability of materials). This will form the “fundus” of the uterus.
- Narrow the foot of the sock by folding the ends over and securing into place with glue or staples to form the body of the uterus.
- Trim any excess sock material.
Part B – Ovaries
[edit | edit source]- Take small (approximately 5x5 cm) squares of cotton fabric and fold into a round ball.
- Secure ends with staples or glue.
Part C – Ectopic Contents =
[edit | edit source]Playdough is preferable if available. Bright colors will be more visible and thus recommended.
- If playdough is not available, Make home-made dough with the following recipe:
- Flour – ½ cup
- Salt – 1/8 cup
- Nescafe- 1/8 cup
- Water – ¼ cup
- Mix dry ingredients.
- Add water, mixing thoroughly. Mixture should form a soft ball. If too soft or hard, add flour or water.
Part D – Fallopian tubes with Ectopic Pregnancy
[edit | edit source]- Take the Penrose drain, securing a suture tie approximately 1/3 of the way along one end.
- Fill a Toomey syringe with dough filling approx. 5-10 cc into the drain, until “ectopic pregnancy” is appropriate size.
- Tie a second tie to keep the dough in place.
- Using a marker or pen, place a single circular mark at the superior side of the ectopic pregnancy. This mark will be used later when practicing intracorporal suturing and knot tying skills.
- Cut 3-4 approximately 1 cm slits in ends of drain to form fimbriae.
Assembly
[edit | edit source]It will be easier to perform the operation if you tape the ectopic simulation to a paper plate, and then tape this paper plate to the table for stability
Ectopic pregnancy (target tissue)
[edit | edit source]Secure tubes to uterus. Using a stapler or fabric glue, secure the center of the Penrose drain to the fundus of the constructed uterus, so that each half is clearly visible to either side. Use plastic wrap to form mesosalpinx. Place uterus, tubes, and ovaries onto a sheet of plastic wrap in appropriate anatomic positioning.
Press second sheet of plastic wrap on top. Trim to appropriate size.
Simulator verification
[edit | edit source]Use this checklist to ensure that the simulator is correctly made and calibrated.
