45 products · sorted by price (high to low)
A laparoscopic trocar has two main parts. The obturator carries the tip, and the cannula is the hollow sleeve that other instruments pass through. Listings here include sharp trocars with triangular tips, blunt obturators and cannulas in several diameters. You will also find Intuitive Surgical da Vinci blunt obturators, including Single-Site designs. Karl Storz and Olympus are among the other makers of these surgical trocars. Clear Choice Medical has no affiliation with any of them.
Diameter is the first spec to match. Listings state it in millimeters, such as 5.5 mm, 10 mm or 11 mm. Then compare working length and tip style, because a trocar and its trocar cannula are normally sized as a pair. Valve and seal designs differ between makers, so check whether a listing includes the valve or seal you need. Cannulas are sometimes listed on their own, so confirm whether the obturator is included before you order. Where a title gives a part number, use it to match the cannula to its system.
Many trocars here are one-off pieces, so the selection changes as items sell. Browse the current listings above, or contact Clear Choice Medical with a question about a specific trocar.
Common questions about Specialty Trocars (Laparoscopic)
What is a Hasson trocar?
A Hasson trocar is a blunt trocar and cannula made for open laparoscopic entry. It is named for Dr. Harrith Hasson, who first described open laparoscopy in 1971. Open-entry ports use blunt obturators rather than bladed or sharp tips. They also have a system that lets the fascia be attached to the port. That attachment keeps the port stable. A listing title may pair a cannula with a Hasson adapter. Check the title for the cannula, the blunt obturator and any Hasson fitting before you order.
What are the different trocar valve types?
A trocar valve is the seal in the cannula that lets instruments pass without losing insufflation. Named designs include trumpet valves, flap valves and silicone leaflet valves. Some valves open automatically as an instrument passes, while others are opened by hand. Valves are also described as oblique, transverse or piston designs. Flexible valves are made to limit gas leaks across different instrument diameters. Listing titles often name the valve, such as trumpet valve, auto valve or ball valve. Match that valve name and the part number to your trocar system.
What is the difference between reusable and single-use laparoscopic trocars?
A reusable trocar is designed for repeated use, while a single-use trocar is intended for one patient and one procedure only. Both types are built from a mix of metal and plastic. Many disposable plastic trocars have a spring-loaded mechanism that withdraws the sharp tip. Makers state reusability in their catalogs. Karl Storz, for example, marks its 11 mm multifunctional valve as reusable. Single-use products carry a do-not-reuse symbol on their labeling. In a listing, look for that symbol or single-use wording on any packaging in the photos.
