TissueDB/Materials/PVC
PVC (polyvinyl chloride) refers to rigid plastic piping commonly used in plumbing and construction. In surgical simulation, PVC pipe serves as a rigid structural substrate in training models, valued for its uniform diameter, predictable rigidity, and global availability.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes | |
|---|---|---|---|---|---|
| Skin | Tourniquet Simulator, Wound Packing Simulator | PVC pipe forms the rigid limb structure beneath the skin layer in hemorrhage control training models. | |||
| Blood Vessel (pump return circuit) | Pulsatile REBOA Simulator (Keller) | 1.3 cm inner diameter polyvinyl chloride tubing for pump inflow and outflow in Keller's pulsatile REBOA simulator vascular circuit; includes a one-way check valve in the return tubing and a proximal circuit shunt to divert antegrade flow during balloon occlusion. Source verbatim: "The pump inflow and outflow are made of 1.3-cm ID polyvinyl chloride tubing".[1] |
Troubleshooting
- Cortical/cancellous differentiation training — PVC has uniform density throughout; it cannot replicate the distinct tactile transition between cortical and cancellous bone. Trainees will not develop the critical haptic skill of recognizing when a drill bit exits cortex and enters softer cancellous bone.
- Intramedullary nailing technique — Empty PVC tubes provide no resistance to reamers or nails. Without medullary canal resistance, trainees cannot learn proper reaming depth control or nail insertion force calibration. Fill with silicone to partially address this limitation.
- Cortical feel differs from bone — PVC drilling feel differs from bone; experienced surgeons can distinguish them. Advanced trainees may develop false confidence from PVC success that does not transfer to clinical bone work.
- Drilling sound recognition — PVC produces different acoustic feedback than bone during drilling. Auditory cues are part of expert drilling technique; PVC does not train this skill.
Alternatives
| Alternative | Best For | Trade-offs |
|---|---|---|
| Animal bone | Cortical/cancellous differentiation | Cultural restrictions; biological waste; single-use |
| Bamboo | Low-cost natural material; globally available | Variable diameter; node irregularities |
| Sawbones (synthetic) | High-fidelity commercial option; sterile | Higher cost (USD 15–50 per unit); less accessible |

Overview
[edit source]PVC pipe is a rigid, uniform-density thermoplastic. Schedule 40 (standard wall) and Schedule 80 (thick wall) are most common for simulation. Available in diameters from 13 mm (1/2 in) to 50 mm (2 in). White, grey, and clear variants available. Can be cut, drilled, and shaped with standard workshop tools. Inexpensive (less than USD 5 per model) and globally available from hardware suppliers.
