Laparotomy Instrument Set: Instruments Used in Open Abdominal Surgery

Laparotomy set list: the main instrument groups

The set is built around eight groups: cutting (scalpel handles, scissors), haemostasis (clamps of several lengths), tissue handling (dissecting and toothed forceps), intestinal clamps and forceps, suturing (needle holders), retraction (hand-held and self-retaining), suction and swab handling, and drapes, bowls and dishes.

Open abdominal surgery instruments are usually longer than those for superficial work, with 18 to 25 cm clamps and 20 cm or longer scissors in common use, because the surgeon works at depth. Sets are often split into a basic tray for access and closure and an add-on tray for the specific procedure, which keeps the number of opened pieces down.

Plan the set around the incision as well. A midline laparotomy needs long instruments and a large self-retaining frame, whereas a smaller transverse or muscle-splitting incision calls for shorter clamps and a smaller retractor. Ask surgeons what they want in both configurations.

Instruments used in abdominal surgery: clamps, forceps and scissors

Haemostatic forceps are the largest group. REDA's forceps and clamps range covers Halsted-Mosquito, Hartmann, Crile, Kelly, Spencer-Wells, Rochester-Pean, Rochester-Ochsner, Kocher and Bengolea haemostats, straight and curved, in several lengths, plus Mixter and Overholt dissecting forceps, towel clamps and Foerster swab forceps. Its catalogue also lists Allis and Babcock intestinal forceps.

Scissors for the abdomen are mainly Mayo for tough tissue and sutures, Metzenbaum for dissection, and a longer curved pattern for deep work. For choosing, read Metzenbaum vs Mayo scissors and long surgical scissors sizes.

Atraumatic bowel handling matters. Allis and Babcock forceps are designed to hold tissue without crushing, but any clamp that touches bowel should be chosen and applied with care. Specify clearly which clamps are meant for tissue that will be resected and which for tissue that must be preserved.

• Haemostats: mosquito, Kelly and Crile for small vessels, Rochester-Pean and Kocher for pedicles.
• Intestinal forceps: Allis and Babcock for gentle holding of bowel and tissue.
• Towel clamps and swab forceps for draping and packing.

Abdominal retractors and exposure

Exposure in a laparotomy depends on retractors: hand-held models such as Deaver and Richardson blades for assistants, and self-retaining abdominal frames. REDA's retractor range lists Deaver, Kelly and Richardson hand retractors, and Balfour and Kirschner abdominal retractors as self-retaining designs.

A self-retaining frame spares the assistants and holds the wound open for the whole case, but it should be checked for tissue compression during long operations. See abdominal retractors Balfour and Kirschner and self retaining retractors.

Sizing the tray: basic versus procedure-specific

Build a general laparotomy tray for the entry and closure stages and add procedure-specific pieces for the resection or repair. Compare with the general surgery instrument set and the major surgery set list for baseline contents, then adjust to your surgeons' preferences.

Include bowls, kidney dishes and instrument trays. REDA's general surgery section lists kidney dishes, round bowls and instrument trays together with probes and needles. Count everything at the start and before closing, in line with hospital policy.

Weight is a practical limit. A fully loaded laparotomy tray can be heavy, and sterile processing departments often split it in two to keep within container and handling limits.

Buying and care

Ask for item-level lengths and sizes, material and finish, and the supplier's repair service. Long instruments need appropriate containers so that the tips are not bent, and heavy sets should be weight-checked against the container load. Check current MOHAP, DHA or DOH requirements.
