Modules	Normal (2), retroversion (2), anteflexion, salpingitis (2), fibroids, ovarian cyst
Dimensions	Full adult female lower torso (abdominal + pelvic)
Price Range	$327–370
Application	Medical schools, midwifery programs, WOCN/OB-GYN residency

1. Module Capability Checklist

Module	Pathology	Palpation Finding	Training Value
1–2	Normal uterus, moderate retroversion	Smooth fundus, posterior angulation	Differentiating normal variant from pathology
3	Normal uterus, forward flexion	Smooth fundus, anterior angulation	Baseline for comparison
4	Left salpingitis	Unilateral adnexal fullness/tenderness	PID sequelae recognition
5	Right salpingitis	Unilateral adnexal fullness/tenderness	Right salpingitis vs. appendicitis differential
6	Myomatous uterus	Irregular, firm, nodular fundus	Most common benign tumor — 70% of women by age 50 (Baird et al., 2003)
7	Marked anteversion-anteflexion	Sharply anterior fundus	Fixed retroversion vs. adhesion differentiation
8	Left ovarian cyst	Discrete smooth adnexal mass	Functional cyst vs. neoplasm evaluation

2. Core Scenario Scripts

Scenario A: Bimanual Palpation Module Drill — 20 min

Objective: Identify uterine pathology by palpation alone, without visual cues.

A survey by Dugoff et al. (2020) of 1,032 graduating US medical students found only 42% felt confident performing unsupervised bimanual examination, and 68% had never palpated an abnormal uterus during training. The BIX-FS turns pathology exposure from probabilistic to guaranteed.

Phase	Time	Trainee Action	Instructor Role
Module setup	—	—	Load module #6 (fibroids); screen from view
Palpation	8 min	Perform bimanual exam; verbalize findings (size, contour, mobility, tenderness)	Observe; no cues
Diagnosis	3 min	State most likely pathology and rationale	—
Module rotation	2 min	—	Swap to module #8 (ovarian cyst)
Second palpation	5 min	Repeat; note contrast with previous finding	—
Debrief	2 min	Compare with answer key	Discuss tactile differences

Progression ladder: Normal → Retroversion → Fibroids → Salpingitis → Ovarian cyst. Students progress only after correctly identifying the current module.

Scenario B: Speculum Examination & Colposcopy — 15 min

Objective: Insert speculum at correct angle, visualize the cervix, and perform a cervical inspection.

Phase	Time	Trainee Action
Preparation	2 min	Explain procedure, position model, select speculum size
Insertion	3 min	Insert at 45° angle, rotate to horizontal, lock open
Visualization	5 min	Locate os, assess discharge/lesions, describe findings
Colposcopy	3 min	Position colposcope, document cervical findings
Removal	2 min	Unlock, partially close, withdraw at same angle

The WHO 2021 cervical cancer elimination strategy calls for training 50,000 additional colposcopists globally by 2030 (WHO, 2021) — the BIX-FS provides the structured practice platform this scale-up requires.

Scenario C: IUD Insertion & Removal — 20 min

Objective: Master uterine sounding and IUD placement/removal technique.

Step	Action	Key Skill
1	Sound the uterus (measure depth, note direction)	Correct sound angle per module orientation
2	Load IUD into inserter	Maintain sterility
3	Insert to fundus	Correct depth stop
4	Withdraw inserter, trim strings	String length 2–3 cm
5	Removal: locate strings, gentle traction	Complete device retrieval

3. Group Session Design

Students	Units	Students per Unit	Rotation	Total Time
6–8	1	3–4 : 1	20-min stations	90 min
8–16	2	3–4 : 1	3 parallel stations	90 min
16–24	3	3–4 : 1	3 parallel stations	90 min

The interchangeable module system allows a single unit to serve 3 parallel stations simultaneously: Station A runs bimanual palpation (module loaded), Station B runs speculum/colposcopy, Station C runs IUD — with 30-second module swaps between rotations.

4. OSCE Station Design

Station	Time	Task	Pass Criteria
1. Bimanual palpation	10 min	Identify pathology from loaded module	Correct diagnosis + rationale
2. Speculum exam	8 min	Insert, visualize, describe cervix	Correct angle, complete visualization
3. IUD insertion	10 min	Sound uterus + place IUD	Depth correct, strings trimmed
4. Pelvic measurement	8 min	Identify ischial spines, sacral promontory	All landmarks located
5. Triple diagnosis	10 min	Bimanual + rectovaginal + speculum	Complete sequence, findings documented

5. Consumables & Maintenance

Item	Replacement Interval	Min. Stock
Cervical os inserts	200–250 IUD cycles	2
Uterine modules	As needed (wear/fatigue)	Full set backup
Lubricant (water-based only)	Monthly	2 bottles
Interval	Action
After each session	Wipe perineum and vaginal canal with mild soap and water
Weekly	Inspect module keying alignment; verify orientation marks
Monthly	Check silicone surfaces for adhesion/stiffness
Quarterly	Lubricate module receiver mechanism
Annually	Full inspection; replace worn modules

Important: Use water-based lubricant only — silicone-based lubricants bond to the model material and cause surface degradation. For replacement modules: chinoncpr@adaanatomy.com.

6. FAQ

Q1: Can the BIX-FS be used for Pap smear training? A: Yes. The cervical os is anatomically positioned for speculum-guided sampling with a cytobrush or Ayre spatula, including correct rotation technique and specimen transfer.

Q2: Does it support rectovaginal examination? A: Yes. The model supports the three-examination technique (bimanual + rectovaginal + speculum) — the gold standard for adnexal and posterior cul-de-sac assessment.

Q3: How many IUD insertions can the uterine cavity withstand? A: Approximately 200–250 cycles before silicone fatigue. The uterine module is replaceable as a consumable.

Q4: Is the model suitable for OSCEs? A: Yes. The interchangeable modules are ideal — examiners pre-load a specific pathology that candidates must identify by palpation alone, per APGO recommendations.

Q5: What is the difference from a basic pelvic model? A: Basic models provide static single-pathology anatomy. The BIX-FS adds 8 interchangeable pathologies with bimanual + speculum + colposcopy + IUD + diaphragm training on one platform with realistic tissue resistance.

Q6: What is the MOQ and delivery timeline? A: MOQ is 1 unit. Air freight: 7–10 business days. For 3+ units (multi-station OSCE deployment), email chinoncpr@adaanatomy.com for volume pricing and consolidated sea freight (30–45 days).
