Clay refers to air-dry or oil-based modeling clay used in medical simulation to represent firm but deformable tissue masses. Clay retains its shape under light pressure and offers modest resistance, making it useful for spatial orientation, lesion modeling, and prototyping anatomical relationships.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Cervix (SCJ) | Cervical Cancer Screening Simulator | Red clay ring around os represents the squamocolumnar junction.[1] | ||
| Acetowhite Lesion | Cervical Cancer Screening Simulator | White clay patches placed adjacent to SCJ replicate VIA-positive lesions.[1] | ||
| Bone | Long Bone Drilling Simulator | Listed as an additional bone-analog option ("play-dough pipe") in the ETALO Basic Simulator Matrix; not demonstrated in the instructional videos. In the demonstrated builds, clay or play-dough instead serves as the soft stabiliser that holds the bamboo or PPR-pipe bone analog on a flat surface during drilling.[2] | ||
| Ectopic mass | Laparoscopic Ectopic Pregnancy Simulator | Commercial playdough, or home-made dough mixed from ½ cup flour, ⅛ cup salt, ⅛ cup Nescafe and ¼ cup water to a soft ball. Inject 5–10 cc into a Penrose-drain fallopian tube and tie off to form the ectopic implantation; mark the superior side as the intracorporeal suturing target. Friable and replaced each session; bright colour improves visibility under the camera.[3] | ||
| Fine nerve branches | Laparoscopic Inguinal Hernia Repair Simulator (Kurashima) | White putty rolled into slender coils and glued to the pelvic wall stands in for the fine nerve branches the trainee should preserve. Putty type is not specified in the source paper. Part of the disposable set, replaced when the model is refreshed.[4] | ||
| Cervix (nulliparous and parous) | IUD Insertion Simulator | Light pink oil-based (stiffer) modelling clay rolled into two cylinders — 2.5 cm diameter by 3 cm long for the nulliparous cervix, 3 cm diameter by 3 cm long for the parous one — with a pencil tip or chopstick pressed through the centre to form a smooth, rounded os on the first and a wider "fish mouth" os on the second. Each mounts on the pegs of the 3D-printed uterus. This build carries no squamocolumnar junction and no lesion, so it is separate from the red-and-white clay rows above.[5] |
Used In Simulators
| Simulator | Purpose | Notes |
|---|---|---|
| Bronchoscopy Anatomical Trainer (Di Domenico) | Sacrificial build form | 500 g of glazier-putty (€0.80) is applied over the wire-and-newspaper scaffold to form the bronchial tree at real scale; the model is then wrapped in food film and covered in 6 to 7 layers of paper-mache. The putty is "part of the build form that is removed when the finished shell is detached". The simulator page lists it under structural parts, not tissues — on this build the clay is the mould, not a tissue, so it carries no row in the tissue table above.[6] |
