5mm or 10mm: choose by the port, not the instrument

The shaft diameter is fixed by the cannula, so the port plan decides the instrument set rather than the other way round. A 5mm shaft passes every 5mm and 10mm port; a 10mm shaft passes only the 10mm. That asymmetry is why most of a lap tray is 5mm and the 10mm instruments are the few that need the diameter to work - large clip appliers, specimen graspers, and the 10mm Maryland dissector where the jaw has to be substantial enough to hold a pedicle.

Length matters as much as diameter and gets less attention. A 33cm shaft is standard; 45cm exists for bariatric and high-BMI cases where the port-to-target distance defeats a 33cm instrument. Buying a 33cm-only set and then meeting a 45cm case mid-list is a common and avoidable problem.

Modular or one-piece: where the money actually goes

A one-piece laparoscopic instrument is simpler and cheaper to buy. When its jaw wears or its insulation fails, the whole instrument is scrap.

A modular instrument separates into insert, outer sheath and handle. The insert is the part that wears - it takes the tissue load and the cleaning cycles - and on a modular system it is the only part replaced. Over a five-year service life the modular route usually costs less per case despite the higher purchase price, and it makes cleaning verification easier because the lumen opens up. The trade-off is assembly discipline: a modular instrument assembled wrong is a modular instrument that fails in the middle of a case.

The failure mode nobody budgets for: insulation

A monopolar laparoscopic instrument carries current down a long, thin, repeatedly autoclaved shaft. The insulation on that shaft develops pinholes - from handling, from cleaning brushes, from thermal cycling - and a pinhole is invisible to the naked eye.

What makes it serious is geometry. The visible field of a laparoscope is a small cone; the shaft passes through tissue well outside it. Current leaving through a pinhole 10cm behind the jaw produces a burn nobody sees at the time, in bowel or vessel, and presents days later. This is the reason insulation testing exists as a discrete step in instrument processing rather than an optional extra, and why an insulation tester belongs alongside a monopolar lap set rather than being treated as a nice-to-have.

Bipolar instruments contain the current path between their own two jaws and remove this failure mode entirely, which is part of why they cost more.

Maryland, Babcock or crocodile: which grasper

These three cover most of what a lap tray grasps, and they are not interchangeable.

The Maryland has a fine, curved, tapered jaw. It is a dissector first and a grasper second - the curve lets it pass behind a structure and open to create a plane. Use it to develop tissue, not to hold it under load.

The Babcock has a broad, fenestrated, atraumatic jaw shaped to hold bowel without crushing it. Wide surface, low pressure. It holds; it does not dissect.

The crocodile has multiple interdigitating teeth along the jaw. It grips hard and it marks whatever it grips - right for a specimen, a suture, or a piece of mesh, wrong for anything staying in the patient.

The general rule holds here as elsewhere: the atraumatic jaw that slips on fascia and the toothed jaw that perforates bowel are the same error from opposite directions.

Frequently asked

Are these reusable or single-use? Reusable, autoclavable instruments. The disposable items in the catalog sit under endoscopy disposables rather than here.

Can I order a modular insert on its own? Yes - inserts, sheaths and handles are listed separately where the system is modular, so a worn insert is replaced without buying a complete instrument.

Do the electrosurgical instruments include a cable? Some are listed with cable and some without; the product title states which. Check before ordering, because cable fittings are not universal across generators.

What is the difference between the 40°, 70° and 90° articulating instruments? The figure is the maximum tip deflection. Higher articulation reaches around a structure from a straight port line, at the cost of some rigidity at full deflection.
