Suture is surgical thread used to close wounds and to join tissues, and in simulation it is the consumable the trainee places into whatever substrate the simulator provides — it is not a tissue simulant itself. A suture is described by three things. The material: silk; nylon, also called polyamide and sold under the brand name Ethilon; polypropylene, sold as Prolene; and the absorbable polyglactin-910, sold as Vicryl. The construction: monofilament, a single smooth strand, or braided, several strands twisted together. And the gauge, on the USP scale, where more zeros means a finer thread — 3-0 is coarse and 10-0 is microsurgical. Thread is normally sold pre-mounted on a needle. A round-bodied (tapered) needle spreads tissue apart rather than cutting it, which is what bowel and vessel work calls for. Non-absorbable types (silk, nylon, polypropylene) stay until someone removes them. Absorbable types (polyglactin) break down in place. This class is the home for every one of those forms — sold as surgical suture, silk suture, silk thread, silk ties and brand-named Ethilon suture. Specific brands and gauges are recorded in the table below and in each simulator's build steps, not in the class title.
Suture is a consumable rather than a tissue simulant. This page therefore carries no tissues table: nothing here stands in for a tissue. The gauge and material are chosen per procedure. Every specification in the table below is the one its published source states.
| Consumable | Quantity | Approximate Cost | Simulator | Notes |
|---|---|---|---|---|
| 9-0 and 10-0 polyamide (nylon) microsuture; 3-0 polyglactin | STA-MCA Bypass Trainer | Microsurgical end-to-side anastomosis. 9-0 and 10-0 polyamide (nylon) microsuture; the source specifies Ethilon, with 5.0 mm (9-0) and 3.8 mm (10-0) round-bodied needles. 9-0 was used in 15 of 24 anastomoses and 10-0 in the other 9; 10-0 also ligates the vessel's accessory branches. 3-0 polyglactin-910 (Vicryl) secures the IV cannulas to the vessel stumps. The dominant consumable cost across the 24-session series. The source's Methods section and the Ethilon brand both indicate polyamide (nylon); its Results and Discussion sections call the sutures "polyethylene" — polyamide is followed here.[1] | ||
| 10-0 nylon microsuture; 3-0 nylon tie | Grapefruit Distal ACA Bypass Simulator | Microsurgical side-to-side anastomosis. 10-0 nylon for the side-to-side anastomosis, consumed during practice. 3-0 nylon serves as the cannulation tie. Practised on grapefruit septal membranes and chicken wing brachial artery segments. This build uses no 9-0.[2] | ||
| 6-0 and 7-0 polypropylene | Vascular Anastomosis Simulator (Cubas) | Bench vascular anastomosis. 6-0 and 7-0 polypropylene on plastic-straw vessel surrogates.[3] | ||
| 4-0 or 5-0 silk, round-bodied (tapered) needle | Neonatal Enterocutaneous Anastomosis Simulator | Bowel anastomosis. 4-0 or 5-0 silk on a round-bodied (tapered) needle. The source chooses inexpensive silk deliberately, to maximise affordability and accessibility for learners in low- and middle-income countries. For the actual procedure on patients, the source notes 4-0 or 5-0 Vicryl or PDS on a round-bodied needle.[4] | ||
| 3-0 silk ties | VesselBox Vessel Ligation Trainer (Hu) | Vessel ligation. 3-0 silk ties. The source used Hefei Fast Nonwoven Products Co (Anhui, China). With reused expired gloves, the silk is the dominant per-attempt consumable cost.[5] | ||
| 3-0 silk | Knot Tying Force-Feedback Simulator (Amiel) | Knot-tying under force feedback. 3-0 silk, a use-time consumable. The source used Sofsilk 3-0 (Medtronic). Tied one-handed square-knot technique.[6] | ||
| Mononylon 4-0 (5-0 and 6-0 named but not preferred) | Suture Simulator (Almeida) | Skin and general suturing practice. Mononylon 4-0 gives the firmest edge apposition and resists tearing. Finer 5-0 and 6-0 threads can tear the pad edges under higher-intensity manual traction.[7] | ||
| 6-0 Prolene (polypropylene) | Lumbar Laminectomy and Dural Closure Simulator (Bakhshi) | Dural closure under the microscope. 6-0 Prolene (polypropylene) closes the latex-glove dura. A use-time consumable, not a build material: the vendors in the source bootcamp supplied it free of charge.[8] | ||
| Silk ties, gauge not stated in the source | Acute Appendicitis Simulator | Appendix stump ligation. Silk ties close the cut, inverted glove. The closed glove retains the sand and cotton fill. The build instructions state no gauge.[9] |
