Purpose
High-fidelity perineal repair trainers for obstetric skills labs. The models reproduce the perineal body, posterior fourchette, vaginal mucosa, and cutaneous layers to rehearse episiotomy creation and layered repair. Instructional aid; not a medical device.
Indications/contraindications and mediolateral vs midline episiotomy selection.
Infiltration lines, scissor angle control (target ~60° from midline for mediolateral), safe protection of the fetal head.
Layered closure: vaginal mucosa → perineal muscles (bulbospongiosus/superficial transverse) → skin.
Suture techniques: continuous locking for mucosa, interrupted/figure-of-eight for muscle, subcuticular/intradermal for skin; knot security and tension control.
Recognition and repair principles for 1st–2nd degree perineal trauma; prevention of OASIS.
Three perineal variants simulating common episiotomy/laceration patterns (midline and mediolateral).
Multi-layer, elastomeric tissue with realistic tear resistance.
Rigid backer for two-handed instrument handling; compact, bench-top footprint.
Durable, latex-free materials; pads tolerate multiple closures and staple/suture removal for repeated use.
Optimized for OSCEs, midwifery/OB-GYN residency bootcamps, and patient-safety drills.
3 × perineal suture blocks (different incision patterns).
Material: medical-grade silicone/elastomer composite, latex-free.
OB-GYN and family medicine residents, midwifery programs, nursing/skills labs, simulation centers, and childbirth educator courses.
