Twenty-five surgical instruments for general operations
Good general operations depend on surgical instruments that each do their own job well. A general operating set is built from instruments that each do one job well, and understanding them by function makes a theatre list far easier to plan and stock. Whatever the operation, a surgeon reaches for tools that cut, grasp, clamp, retract or close, and grouping instruments this way reflects how they are actually used at the table.
The twenty-five instruments below are arranged by that function rather than by procedure. They form a familiar backbone across many general operations, though every specialty and every surgeon adds their own preferences to a set.
How the list is grouped
The instruments fall into five functional groups: cutting and dissecting, grasping and holding, clamping and occluding, retracting and exposing, and suturing and closure. This mirrors the sequence of a typical operation, from incision through to closing.
Cutting and dissecting
These instruments open and separate tissue, and a surgeon reaches for them from the very first incision onwards through the operation.
- Scalpel handles — holding disposable blades for the incision.
- Mayo scissors — sturdier scissors for cutting heavier tissue.
- Metzenbaum scissors — finer scissors for delicate dissection.
- Suture scissors — dedicated to cutting suture material.
- Dissecting forceps — toothed and non-toothed for handling tissue while dissecting.
Grasping and holding
This group holds tissue steady so that each step of an operation can be carried out with control and precision.
- Tissue forceps — holding tissue steady during a step.
- Allis forceps — grasping tissue firmly without excessive trauma.
- Babcock forceps — holding delicate structures gently.
- Sponge-holding forceps — handling swabs and preparation.
- Towel clips — securing drapes around the operative field.
Clamping and occluding
Controlling bleeding and occluding structures relies on these clamps, which come in a range of sizes and strengths for different tissue.
- Artery forceps — clamping vessels to control bleeding.
- Mosquito forceps — fine clamps for small vessels.
- Kocher forceps — stronger clamps for tougher tissue.
- Right-angle forceps — reaching around structures to clamp or pass.
- Needle holders — gripping the needle securely during suturing.
Retracting and exposing
Good exposure makes an operation safer, and these instruments hold tissue aside to reveal the working area clearly.
- Handheld retractors — holding tissue aside for access.
- Self-retaining retractors — keeping a wound open without an extra pair of hands.
- Abdominal retractors — exposing deeper structures in general surgery.
- Skin hooks — fine retraction of skin edges.
- Malleable retractors — shaped to the exposure required.
Suturing and closure
Bringing tissue back together at the end of an operation depends on this group, from needle holders through to the closure materials themselves.
- Needle holders for closure — driving the needle through tissue on closing.
- Tissue forceps for closure — approximating edges during suturing.
- Suture material — a range of absorbable and non-absorbable sutures.
- Skin staplers — rapid skin closure where suitable.
- Wound closure strips — supporting closed edges.
Planning the purchase
Instruments are bought and managed as sets rather than individually, so a theatre plans around the trays it needs for its procedure list. Standardising sets to defined contents makes reprocessing, counting and restocking far more reliable, since staff know exactly what a tray should hold. Instrument quality matters because these tools are handled, reprocessed and relied upon repeatedly, and a set that stays sharp and true through many cycles serves a theatre well. Working with the sterile services team on set contents and quantities keeps enough trays in circulation to match the operating schedule.
Points to confirm before ordering
- Set contents. Define the instruments each tray should hold for its procedures.
- Quantities. Confirm enough sets to match the operating schedule and reprocessing.
- Quality. Establish instruments that stay sound through repeated reprocessing.
- Reprocessing. Confirm sets suit the sterile services workflow.
- Counting. Establish clear tray lists supporting reliable counts.
Servicing and safety
Surgical instruments are reprocessed constantly and inspected for damage, sharpness and function, since a worn or faulty instrument can affect a procedure. Agreeing repair, sharpening and replacement arrangements keeps sets in good order, and clear tray lists support counting and stock control. Ensure the theatre receives published device safety alerts so field safety notices reach the surgical and sterile services teams.

Bringing the list together
Understanding a general set by function, from cutting through to closure, makes stocking and managing a theatre far clearer. Standardised set contents, enough trays for the schedule and reliable reprocessing turn these twenty-five instrument types into a dependable operating service. Understood this way, the surgical instruments make a general set easy to work with.
