Soap (bar soap, glycerin soap) is a solid, mouldable cleansing product used in surgical simulation as a very-low-cost substrate for basic needle-handling and suturing practice. It offers resistance to a needle but does not tear, deform, or layer like real tissue, so its use is limited to absolute beginners.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Soft tissue | — | Basic suturing practice. Bar soap at room temperature provides resistance to the needle; suitable for absolute beginners developing basic needle-handling skills. Does not teach proper tissue eversion or wound care. |
Troubleshooting
- Realistic tissue handling — soap does not tear or deform like tissue; use silicone or foam for realistic manipulation.
- Advanced suturing technique — does not teach proper tissue eversion or edge approximation; use banana peel for layered practice.
- Wet environments — dissolves with water exposure; keep dry during use.
Alternatives
| Alternative | Best For | Trade-offs |
|---|---|---|
| Banana peel | Layered, skin-like suturing practice | Single-use, degrades quickly |
| Silicone | Durable practice | Higher cost |
| Foam (EVA) | Basic needle practice | Different needle feel |
