Carlson, MD, FACOGkscarlson@unmc.eduDepartment of Obstetrics and GynecologyOctober 2023The task trainer base is described in this article: Hellier SD, Ramponi DR, Wrynn A, Garofalo S. An Innovative Approach: Using Simulation to Teach Primary Care Gynecologic Procedures. Simul Healthc. 2017 Aug;12(4):268-273. doi: 10.1097/SIH.0000000000000213. PMID: 28072606.The uterus, cervix and connecting piece were designed by Jami Monico and Dr. Karen Carlson.SourcesFeatures▪ Tabletop design▪ Reusable ▪ Silicone cervix▪ Pliable material▪ Patent cervical os▪ Viscous substance inside uterus represents tissueSimulate gynecologicalprocedures, including:▪ Tenaculum placement on the cervix▪ Cervical cancer screening▪ Measure uterine depth with a sound▪ Endometrial biopsy▪ Intrauterine device placement and removal▪ Manual vacuum aspirationSilicone cervixFrom left to right: Uterus, cervix, connecting piece, and PVC pipe simulates the vagina• With the tabletop design, the simulation can be done with multiple learners in one classroom.• Decide how many task trainers your program needs, then proceed with obtaining the supplies.Time to create one task trainer and durability1. The 3D printing will take the longest and the print time depends on the machine.• Very durable2. Silicone cervix – the cure time for the Ecoflex 00-20 is 4 hours.• The silicone cervix should last for repeated uses. Potential damage to the cervix is from tenaculum placement.3. Wood base and PVC pieces – quick to assemble• Very durableHow Many Task Trainers Do You Need?Task Trainer Base1. Wood base, approximately  ¾” x 10” x 10”2. Charlotte pipe coupling  1.5” x 2” PVC DWV Hub x Hub increaser/reducer3. PVC pipe 1.5-inch diameter x 6-inch length4. PVC DWV All Hub Sanitary Reducing Tee  2 x 2 x 1.5 inches5. Gorilla construction adhesive – 1 tube6. Hook and loop tape with adhesive - white, ¾ inch, approximately 5” per task trainer3D-Printed ItemsAccess to a 3D printerFilament for 3D printing: For each task trainer, create one uterus and one connecting ring. Create at least one 3D-printed cervix mold – mix and pour silicone intothe mold to create the cervix. The links to the 3D print files (.stl file format) are below.a) Uterus - print with translucent PLA or other hard plastic, 48 grams. File: https://webmedia.unmc.edu/medicine/OBGYN/3D/uterus.stlb) Connecting ring - print with red PLA or other hard plastic, 35 grams. File: https://webmedia.unmc.edu/medicine/OBGYN/3D/connecting-ring.stlc) Cervix mold - print in any color of PLA or other hard plastic, 38 grams.

Ecoflex 00-20 Super Soft Shore Platinum Silicone Rubber Compounda) Approximately 3 ounces per cervix (part A 1.5 oz and part B 1.5 oz)b) Silicone ease release, 1 can2. Silc Pig Silicone Pigments – “blood” color3. Stir sticks4. 3 disposable plastic cups, 12-16 ounces5. Painter’s plastic or plastic wrap – to cover the work surface when creating the silicone cervixPolyps1. Red pipe cleaners –approximately 2 inches for each polypGel – to simulate uterine tissue/contents1. Thick-It liquid thickener2. Red food coloring3.

Assemble supplies for the silicone cervix from slide 3.2. Protect the work surface with plastic.3. Place cervix mold, curved side down, on a disposable cup.4. Spray release onto the cervix mold.5. Part A • Silicone • Pour 1.5 oz (3 tablespoons) of part A into a plastic cup. Add a small amount of red dye and mix well.Dye6. Part B • Silicone • Pour 1.5 oz (3 tablespoons) of part B into the A cup and mix well.AA B7. Pour the mixture into the mold and allow to cure per manufacturer instructions.8. Gently remove the cervix from the mold.Tip: Create many at a timeCervical polyps may be added to the cervix prior to the simulation. Follow these directions prior to placing the uterus/cervix/connecting ring onto the PVC apparatus.1. Cut red pipe cleaner about 2” in length.• Twist the ends together to form a loop in the middle.2. Make a small incision in the cervix at the desired location of the polyp.3. Insert the pointed end of the polyp into the incision.Cervical PolypspolypWood base ¾”-1” x 10” x 10” *Sand and paint as desiredCharlotte pipe coupling 1.5” x 2” *Glue the 2-inch diameter end onto the middle of the base with construction adhesive.PVC pipe 1.5” diameter, cut to 6” length *Insert one end into the coupling piece.PVC sanitary reducing “T” 2” x 2” x 1.5”*Place the 1.5” end onto the PVC pipe.

Apply sticky-back hook-and-loop tape (Velcro) to the outer edge of the end of the PVC pipe where the uterus will be placed. The Velcro should last for repeated uses.2. Apply the other side of the hook-and-loop tape to the inner edge of the connecting ring.3. If using simulated uterine tissue, mix Thick-It with water until a pudding-like consistency. Add a drop of red food coloring and pour into the uterus. 4. Assemble the uterus, cervix, and connecting ring. Pass the knobs on the outer ring through the holes on the uterus and twist the uterus to secure the pieces. 5. Place the connecting ring onto the end of the PVC sanitary “T”.
