Hospitals, clinics and distributors rarely buy surgical instruments one piece at a time. They buy surgical instrument sets: ready-made trays that contain everything a team needs for one type of procedure. A well-built set saves time in the operating room, makes sterile processing easier and keeps costs predictable. A badly built one leaves surgeons asking for missing instruments halfway through a case.
This guide lists what goes into the most common sets, from a small minor surgery instrument set to a full major (laparotomy) set, plus the specialty sets buyers ask us for most often. Use it as a checklist when you build tenders, compare suppliers or design your own private-label kits.
What is a surgical instrument set?
A surgical instrument set (also called a surgical kit or instrument tray) is a standard group of reusable instruments packed together, sterilised together and opened for a specific procedure. Most sets are built around the same four jobs every operation needs:
- Cutting: scalpel handles and surgical scissors.
- Grasping and holding: tissue forceps, dressing forceps and clamps.
- Clamping (hemostasis): hemostatic forceps that stop bleeding.
- Exposing and closing: retractors to open the field, and needle holders to suture.
The size of the set depends on the depth of the procedure. A skin lesion needs a dozen instruments; an abdominal operation can need 60 to 120.
Minor surgery instrument set (list)
A minor surgery set is the most widely purchased kit in the world. GP surgeries, emergency rooms, dermatology and plastic surgery clinics, and day-care units use it for suturing wounds, removing cysts and lipomas, skin biopsies, abscess drainage and nail procedures. A typical minor set contains:
| Instrument | Typical size | Qty |
|---|---|---|
| Scalpel handle No. 3 | 12.5 cm | 1 |
| Adson tissue forceps, 1×2 teeth | 12 cm | 1 |
| Adson dressing forceps, serrated | 12 cm | 1 |
| Iris scissors, straight and curved | 11.5 cm | 2 |
| Metzenbaum scissors, curved | 14 cm | 1 |
| Suture (stitch) scissors | 14 cm | 1 |
| Halsted mosquito forceps, straight and curved | 12.5 cm | 4 |
| Webster or Mayo-Hegar needle holder | 13-15 cm | 1 |
| Allis tissue forceps | 15 cm | 1 |
| Senn retractor, double-ended | 16 cm | 1 |
| Skin hooks, single | 16 cm | 2 |
| Backhaus towel clamps | 11 cm | 2 |
| Probe with eye | 14 cm | 1 |
| Kidney dish and gallipot (optional) | stainless steel | 1 each |
Buyer tip: order the needle holder and scissors in a tungsten carbide (TC) version for clinics that do a lot of suturing. TC jaws grip the needle better and last much longer, and the gold handles make them easy to spot on the tray.
Basic surgery set
A basic surgical instrument set sits between minor and major. It is used for hernia repair, appendectomy, superficial lumps, small orthopaedic procedures and many caesarean or gynaecology cases when combined with a few specialty items. On top of the minor set, it usually adds:
- Scalpel handles No. 3 and No. 4
- Mayo scissors, straight and curved (for heavy tissue and sutures)
- Longer tissue and dressing forceps (15-18 cm)
- Kelly, Crile and Kocher hemostatic forceps (6-10 pieces)
- Babcock forceps for bowel and delicate tubular tissue
- Langenbeck and Czerny retractors
- Sponge-holding forceps (Foerster or Rampley) for skin prep
- Two needle holders in different lengths
Major surgery (laparotomy) set
A major surgery set, often called a laparotomy set or general surgery set, is used for open abdominal and other deep procedures. It needs longer instruments, more clamps and self-retaining retractors. Typical additions:
- Long Metzenbaum and Mayo scissors (18-23 cm)
- DeBakey atraumatic forceps for bowel and vessels
- Long Kelly, Rochester-Pean and right-angle (Mixter) clamps
- Doyen intestinal clamps (soft) and Kocher clamps (crushing)
- Retractors: Balfour self-retaining retractor, Deaver, Richardson and Kelly retractors, malleable ribbons
- Poole and Yankauer suction tubes
- Long needle holders (Mayo-Hegar 20-24 cm)
- Towel clamps, sponge holders and a bowl set
Major sets often run to 80-120 pieces. Many hospitals split them into a “base tray” and a smaller “add-on tray” so sterile processing teams handle lighter, safer loads.
Common specialty sets
Beyond general sets, these are the specialty kits that distributors and tender buyers request most:
- Delivery (obstetric) set: episiotomy scissors, cord scissors, Kocher and Pean clamps, sponge-holding forceps, needle holder and tissue forceps. See our gynecology instruments list.
- D&C set: vaginal specula, uterine sound, Hegar dilators, sharp and blunt curettes, tenaculum and sponge forceps.
- Caesarean section set: a basic set plus Doyen bladder retractor, Green-Armytage clamps and uterine forceps.
- Tonsillectomy set: Boyle-Davis mouth gag, tonsil dissectors, holding forceps, snare and adenoid curette. Browse our ENT instruments.
- Orthopaedic / small bone set: rongeurs, bone cutters, osteotomes, mallet, curettes and bone holding forceps. See orthopedic instruments.
- Dental extraction and oral surgery kits: extraction forceps, elevators, periosteal elevators, bone rongeurs and needle holders.
- Veterinary surgery sets: spay and castration packs for small animals and field kits for large-animal practice.
How to choose a surgical instrument set supplier
When you buy sets in volume, the supplier matters more than the catalogue photo. Check these points before you place an order:
- Steel and hardness. Cutting and clamping instruments should be martensitic stainless steel (AISI 410/420), correctly hardened. Read our guide to surgical steel grades.
- Box locks and ratchets. Every hemostat and needle holder should close smoothly, with jaws aligned and ratchets holding at each tooth.
- Standards and documents. Ask for ISO 13485 quality management, CE documentation for Europe and material certificates. Instruments should meet ISO 7153-1 and ASTM F899.
- Set customisation. A good manufacturer builds sets to your list and sizes, not only fixed catalogue sets.
- Sterilisation containers. Perforated baskets, silicone mats and container systems keep instruments organised and protected during autoclaving.
- Samples first. Always test a sample set before committing to a large order. You can request samples from Pak Line here.
Caring for instrument sets
Sets last for years when they are cleaned and sterilised correctly. Open all box locks before cleaning, separate delicate instruments, never leave blood to dry on steel, and lubricate hinges with instrument milk before autoclaving. Follow our step-by-step cleaning and sterilisation guide.

FAQs
What instruments are in a minor surgery set?
A standard minor surgery set includes a scalpel handle, toothed and non-toothed tissue forceps, iris and Metzenbaum scissors, suture scissors, mosquito hemostats, a needle holder, an Allis forceps, a small retractor, skin hooks and towel clamps.
How many instruments are in a major surgery set?
A major (laparotomy) set usually contains 60 to 120 instruments, depending on the hospital’s procedures and whether retractors are packed in a separate tray.
What is the difference between a basic and a major surgical set?
A basic set covers shallow and moderate procedures with standard-length instruments. A major set adds long instruments, more clamps, intestinal clamps and self-retaining retractors for deep abdominal surgery.
Can I order a surgical set with my own instrument list?
Yes. Pak Line builds custom sets to your list, sizes and branding, with sterilisation baskets and private-label packaging.
Are reusable surgical sets better value than single-use kits?
For most hospitals, reusable stainless steel sets cost less per procedure over their lifetime and create far less waste. Single-use kits can make sense where sterile processing capacity is limited.
