Surgical instruments for cesarean section: set composition by step

How maternity units build a C-section instrument set

There is no single universal list. Composition depends on the surgeons' preferences, the hospital's incision and closure technique, and whether the unit uses one large basic set plus add-on packs. What does not change is the logic: a basic laparotomy-style set covers the abdominal wall, a few instruments are specific to the uterus and delivery, and closure instruments return to the general pattern.

Most units standardise a single C-section tray used by every surgeon, because standard trays shorten set-up, reduce errors in the count and simplify CSSD assembly. Teams should agree the list in a multidisciplinary meeting and record it as a controlled document.

Typical instruments by operative step

The following grouping is a general illustration that your clinical team will adapt. Quantities are decided locally.

Instruments for sets are widely available in standard patterns from the German tradition; see also our guide to general surgery instrument sets and the notes on laparotomy instrument sets, which share most of the abdominal-wall components.

• Incision and exposure: scalpel handles with blades, dissecting and tissue forceps, Mayo and Metzenbaum scissors, haemostatic forceps (Kelly, mosquito), towel clips and an abdominal self-retaining or hand-held retractor set.
• Uterine phase: a bladder blade or retractor, long scissors, Allis or Babcock-type grasping forceps, sponge-holding forceps, suction tubing and cannula, and ring or ovum forceps where the unit uses them.
• Delivery and cord: cord clamps, cord scissors and kidney dishes for the placenta.
• Closure: needle holders, suture scissors, tissue forceps, and the same haemostatic forceps for bleeding points.
• Support: instrument bowls, trays, basins and the counting sheet.

Obstetric and gynaecological patterns from REDA

REDA's gynaecology section lists obstetric forceps (Simpson and Wrigley), Hegar uterine dilators, uterine curettes, uterine sounds, tenaculum and biopsy punch forceps, ovum forceps and aspiration curettes, together with vaginal specula. Not every item belongs in a C-section tray, so check the REDA gynaecology instruments range against your list instead of ordering by section.

The REDA general surgery range covers everyday OR items including needles, bipolar coagulation forceps (straight, 45° angled and bayonet), kidney dishes, round bowls and instrument trays, which are the support pieces most trays need.

Counting, tray layout and reprocessing

A good tray is laid out so the count is quick. Group instruments by type, keep ring-handled instruments open on a stringer or in an organiser, and give each tray a laminated list. Instruments should be counted at the start, before closure of the uterus, before closure of the fascia and at the end, according to the hospital's policy.

For reprocessing, assemble sets that fit your containers and your steriliser load. Rigid containers such as the REDA container system come in full, three-quarter and half sizes (580, 465 and 285 × 280 mm footprints), so you can match tray weight to handling limits. Validate cleaning, packing and sterilization against ISO 17665 principles and your CSSD procedures.

What to check when buying or replenishing sets

Ask for the material grade, finish and tolerance of the instruments, and request an instrument list with article numbers so that replacement pieces can be reordered individually. Check whether the supplier can provide repair or sharpening support, and confirm product registration before ordering.

Treat sets as living lists. Review tray content against case logs twice a year, remove unused instruments, and track losses and damage so that reorders are based on data. Beckfinity can support this with documentation from REDA, and you can request a set proposal via our contact page.
