Building a minor surgical instrument set: a practical checklist

What a minor set is meant to do

A minor set supports procedures under local anaesthesia that do not open a body cavity: excision of cysts or lesions, drainage, biopsy, laceration repair and suture removal. It is not a general surgery set, which is far larger and includes retractors and long instruments. See our general surgery instrument set for comparison.

The aim is a tray that one nurse can set up in minutes, that fits a standard sterilization container, and that can be counted in a few seconds before and after use.

Resist the urge to add rarely used items. Every extra instrument adds reprocessing time, counting effort and loss risk.

Core instruments and typical quantities

A basic minor set generally includes a scalpel handle, tissue forceps with teeth, dressing forceps, straight and curved scissors, two to four small haemostatic forceps, a needle holder and a towel clip or two. Departments vary, so treat the list below as a starting point and adjust to local practice.

Choose lengths for superficial work, usually in the 12 to 15 cm range for forceps, haemostats and needle holders. REDA lists these families in its forceps and clamps, surgical scissors and needle holder ranges, in several lengths and patterns.

• Scalpel handle with blades supplied separately
• Toothed tissue forceps (for example 1×2 teeth)
• Non-toothed dressing forceps
• Straight and curved scissors, plus suture scissors
• Halsted-Mosquito or similar haemostatic forceps, two to four
• Mayo-Hegar needle holder
• Towel clamps and a small kidney dish

How to choose each instrument

Haemostats: small Halsted-Mosquito forceps handle superficial vessels, and a Kelly or Crile type gives a second size. Needle holders: a Mayo-Hegar pattern in the 14 to 15 cm range copes with most skin sutures, and TC jaws suit departments with heavy daily use.

Scissors: a blunt-tipped curved pair for undermining, and a straight pair for cutting sutures and dressings. Our curved versus straight scissors guide explains the logic.

Forceps: pair one toothed forceps for the skin with a smooth one for handling dressings. See toothed versus smooth forceps.

Variants for suturing and drainage

If your clinic sees many lacerations, you may want a dedicated suture and laceration set with a spare needle holder and suture scissors. For abscess care, an incision and drainage set adds a probe and a blunt dissector.

Standardising on two or three variants, rather than inventing a new tray for each doctor, simplifies stocking and training.

Reprocessing, counts and common mistakes

Count every instrument before the first incision and again before closure, and record the count according to your facility policy. A compact set with identical items in a fixed layout makes counting reliable.

Common mistakes include overloading the tray, mixing different lengths of the same pattern, leaving ratchets locked during sterilization and failing to inspect scissors and needle holders after each cycle. Open ratchets to the first tooth, keep sharp tips protected and send worn instruments for service before they affect a procedure.

Label each tray with a content list and a set number. If an instrument is missing, the list tells staff what to replace without opening several sets.

Buying and maintaining the set

Ask for a documented sample, check that ratchets lock cleanly and that scissor blades meet smoothly. Decide how many identical sets you need so that one is always available while others are reprocessed. Plan for repair and sharpening.
