Shepard Trocar Ø 5 to 8 mm, 14.5 cm - 5-3/4˝
The Shepard trocar is the pointed obturator that sits inside a Shepard cylinder osteotome to centre and start the cut, supplied in Ø 5, 6 and 8 mm on a 14.5 cm shaft. The ground point bites the cortex so the cylinder does not skate across the bone graft donor site, then withdraws and leaves the tube to cut its core. Choose your diameter from the dropdown. Bulk discounts apply on multi-piece and full-set orders.
Why Surgeons Choose It
- Three-sided ground point bites cortical bone instead of skating
- Diameters match the Ø 5, 6 and 8 mm cylinder osteotomes exactly
- Flat strike cap takes mallet blows without spreading
- Knurled collar stays controllable through gloves and irrigation
- 14.5 cm shaft sets the cut depth with the point still in view

Built for Repeated Use
Turned and ground from AISI 420 martensitic stainless steel, hardened so the point keeps its bite and the strike cap takes repeated mallet blows without mushrooming. The satin finish resists staining and glare, and the one-piece body has no joint to loosen or trap debris. Full autoclave cycles at 134 °C cause no distortion or pitting.

Frequently Asked Questions
Which diameter do I need?
The one that matches your cylinder osteotome, so a Ø 6 mm trocar for the Ø 6 mm cylinder. Most surgeons who keep all three cylinders keep all three trocars.
What is the trocar for?
It centres the cylinder osteotome and starts the cut so the tube does not skate on cortical bone. Once the cylinder is seated, the trocar comes out and the cylinder cuts the core.
How is this different from the ram?
The trocar is pointed and goes in first to start the cut. The ram is blunt and goes in afterwards to push the harvested core out of the cylinder.
Can the point be resharpened?
Yes, by a competent instrument workshop. The hardened steel takes a regrind, though keeping the original three-sided geometry matters more than absolute sharpness.
What steel is used?
AISI 420 martensitic stainless steel, hardened and ground, chosen because it holds a point and tolerates repeated autoclaving without pitting.
Is it supplied sterile?
No. It ships clean and non-sterile, ready for your own cleaning and autoclave cycle at 134 °C before first use.
