Major Basic Instrument Set, 98 Pieces

What a major basic instrument set is

General surgery trays come in two basic sizes. A minor set covers skin, small lumps and wounds. A major set is for the operation that opens a body cavity or runs a long incision, where the team needs more clamps, deeper retractors and longer needle holders than a minor tray can hold.

Google AI Mode, read on 27 October 2026, describes a major basic surgery set as a standard collection of instruments for wide exposure open operations, with major abdominal surgery and general soft tissue work among them. The groups it lists are the groups this tray is built from: scalpel handles, Mayo and Metzenbaum scissors, mosquito and Crile forceps, Allis and Babcock forceps, sponge and towel forceps, Richardson, Deaver and malleable retractors, a Balfour, Mayo Hegar needle holders and a Yankauer tube.

Ours is the same 98 piece tray we sell as the laparotomy instrument set, listed a second time for buyers who order by the general surgery name. A buyer looking for a major surgery instrument set is looking for this box, and anyone asking for the basic instruments for surgery, or the instruments used in surgery, finds one full answer in the contents table.

Key design features

Seven pairs of scissors

Two Mayo scissors, 17 cm, one straight and one curved, take the heavier cuts through fascia. Four Metzenbaum Nelson scissors, all curved and blunt at both points, do the fine dissection: two at 18 cm for work near the surface and two at 23 cm for the deep field. A 14.5 cm sharp blunt operating scissors stays on the back table for sutures and dressings.

Forceps to grasp, from fine to firm

Fourteen grasping forceps sit beside the clamps. Three plain dressing forceps and three tissue forceps with 1 x 2 teeth, at 14.5 and 20 cm, cover the surface. Two Potts Smith dressing forceps, 21 and 25 cm, reach into the abdomen. Four Allis forceps hold tissue that has to be pulled on, and two Babcock forceps hold the bowel without biting through it.

A retractor for each layer

Volkmann rakes with four and six prongs, a Roux set, a Parker Langenbeck set and two Cushing hooks hold skin and fat. Four Richardson retractors and two Deavers work deeper. The 200 mm Balfour holds the abdomen open by itself once its blades are set. Three malleable spatulas, 33 cm long, are bent at the table to whatever shape the case needs.

Four handles for four kinds of cut

The No. 3 handle takes the small blades used for fine incisions. The No. 4 takes the large blades for skin and long cuts. The No. 7 is a long, slim handle for small blades in a deep wound, and the No. 7K completes the set. With four handles, two surgeons can cut at once.

The major surgical instruments list

All 44 lines of the tray, read off our own contents list on 27 October 2026. The quantities add up to 98 instruments. The box is listed last and is not counted as a piece.

Where it is used

The first two columns come from the Google AI Mode answer read on 27 October 2026, the last from our list. Gemini, read on 3 November 2026, places a set like this in general, acute care and abdominal trauma surgery.

What it is for, and what it is not for

A major tray is the general answer. The table sends the narrower jobs to a set of ours that is built for them.

How it compares with the rest of the family

Five open abdominal trays make up this family on our site. The counts are read off each set’s own contents list, and the prices off each product’s order form.

Materials and finish

Every instrument in the set is made from high quality medical grade stainless steel, and the box is stainless steel as well. The steel itself is made to a German specification. We do not publish a grade number.

Because the tray is one list in one box, two identical boxes can be swapped between cases while one is in the steam cycle.

Caring for it

Rinse the tray as soon as the case ends, before blood dries in the joints. Open every jointed instrument so the brush reaches the box joints and the serrations, and run water through the Yankauer tube. Keep the Metzenbaum scissors apart from heavy instruments in the washer. Dry, oil the joints lightly, steam sterilize the tray with the jointed instruments open on a stringer, and count it against the contents list before the box is closed.

The major basic instrument set is made by Adas Instruments in our own workshop and sold direct, which is why the price sits where it does against the catalog houses.

Frequently asked questions

What is a major basic instrument set used for?

It is used for open operations that need wide exposure, above all major abdominal surgery and other open soft tissue work. One box holds the scalpel handles, scissors, clamps, grasping forceps, retractors, suction and needle holders the team needs from the first cut to the last stitch.

What are the common instruments used in major surgery?

Scalpel handles, Mayo and Metzenbaum scissors, artery forceps such as the mosquito and the Crile, Allis and Babcock forceps, towel and sponge forceps, hand held and self retaining retractors, a suction tube and needle holders. Every one of those groups is in this tray, counted in the contents table.

What is the difference between a major basic and a minor basic instrument set?

Size and depth. A minor set handles skin and small wounds and has no deep retractors. The major set adds long scissors, 32 artery forceps, Deaver and Richardson retractors, a Balfour and long needle holders, so it can work inside an open abdomen.

Is the major basic instrument set the same as the laparotomy instrument set?

Yes. The two listings carry the same 98 pieces, in the same sizes and counts, at 643.65 dollars. Some buyers order by the general surgery name and others by the operation, so we list the tray under both. Either order brings the same box.

What is in a surgical kit?

A surgical kit is any set of instruments packed together for one kind of work, from a five piece suture kit to a tray of a hundred pieces. This one holds 98, and every line of it, with sizes and counts, is in the table on this page.
