TissueDB/Materials/Suture

Suture is surgical thread used to close wounds and to join tissues, and in simulation it is the consumable used to practise suturing, knot-tying and vascular or bowel anastomosis. It is not a tissue simulant — it is the thread the trainee places into whatever substrate the simulator provides. Sutures are described by a material (for example nylon/polyamide, polypropylene, polyglactin such as Vicryl, or silk) and a gauge on the USP scale (more zeros means a finer thread — 3-0 is coarse, 10-0 and 11-0 are microsurgical). Both non-absorbable (nylon, polypropylene, silk) and absorbable (polyglactin) types are used in TissueDB simulators. Specific brands and gauges are recorded in the notes, not the class title.

Overview

Suture is bought as sterile packaged thread, usually pre-mounted on a needle, and is single-use per pass. In TissueDB simulators it appears as a build and practice consumable rather than as a material that simulates a tissue: coarse gauges (3-0 to 5-0 silk, polyglactin or nylon) are used for bowel and general suturing practice, and very fine microsurgical gauges (9-0, 10-0, 11-0 nylon/polyamide) are used for vascular anastomosis under an operating microscope (for example the grapefruit distal-ACA bypass and the STA-MCA bypass trainer). Because gauge and material are chosen per procedure, the specific thread is named in each simulator's build steps; this page is the generic class those references resolve to.

Synonyms

Common names: Surgical suture, suture material, surgical thread, stitch. By material: nylon (polyamide) suture, polypropylene suture, polyglactin (Vicryl) suture, silk suture, silk thread. By use: non-absorbable suture, absorbable suture, monofilament suture, braided suture, microsuture. Brand names (for example Ethilon monofilament nylon) are recorded in the notes, not the class title.
