TissueDB/Materials/Plastic bottle
A plastic bottle is a moulded drinks container, reused or cut into sections, and the two builds that use one use it for opposite reasons. Duboureau et al. (2021) use its shape: the top of a bottle larger than one litre, inverted and tilted, is the inguinal canal, and the neck below it is the internal inguinal ring. The neck calibre was not incidental — it was chosen because it matched an infant's internal inguinal ring, and the source records that a smaller bottle was tried and rejected because the mouth size did not resemble the infant's anatomy.[1] The Foley Catheter Tamponade Simulator uses its volume: a bottle larger than 32 oz is used as the reservoir that collects water returning from the fluid circuit, costed at US$1.50.[2] In the Duboureau build the assembled bottle is kept between learners and only the gloves are replaced, so one bottle serves many sessions.[1]
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Inguinal canal | Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau) | The top of the bottle, cut 7 cm below the neck, inverted to form a funnel and tilted so that its axis matches the orientation of the inguinal canal relative to the abdominal wall. The source specifies a bottle of volume greater than one litre.[1] | ||
| Internal inguinal ring | Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau) | The neck of the same bottle, with the cap and the plastic ring beneath it removed. The neck calibre was selected because it mimicked the infant's internal inguinal ring; smaller bottles were tested and rejected because the mouth size did not resemble the infant's anatomy. The peritoneum is closed with an intracorporeal knot at this neck.[1] |
Used In Simulators
| Simulator | Purpose | Notes |
|---|---|---|
| Pediatric Laparoscopic Inguinal Hernia Repair Simulator (Duboureau) | (Structural chassis — holds and mounts the assembly; not a tissue simulant) | The bottle is cut at two points, 7 cm below the neck and 7 cm from the bottom, and the intermediate cylindrical section is discarded. The reserved base is pierced in the centre and joined to the funnel by an elastic loop knotted around the neck, so the two parts stay together inside the laparoscopic-trainer box, where the assembly is taped at its angle. Model parts are costed at about US$5 in total; no per-item price is given for the bottle.[1] |
| Foley Catheter Tamponade Simulator | (Structural — fluid reservoir; not a tissue simulant) | One plastic water bottle, US$1.50, collecting the water returning from the simulator circuit. The guide lists a plastic water bottle larger than 32 oz and gives an empty water bottle as the water-tank example. The pump feeds the mechanism and the mechanism drains to this reservoir, completing the circuit.[2] |
