Abstract
A trephination apparatus can include a first member, a blade, and a second member. The first member can include a through-aperture and a first internal chamber. The first member can also include opening to the first internal chamber that can surround the through-aperture in a plane. The blade can have an outwardly-facing male profile at least partially matching the through-aperture and have a cutting edge. The second member can include a first body sized to be received in the through-aperture with the blade. The blade can be positionable between the first body and the female profile at the second opening. The second member can also include a second internal chamber with an opening extending about the aperture axis in the plane with an opening to the first internal chamber.
Claims20
A trephination apparatus comprising:
- a first member with:
- a through-aperture extending between a first opening and second opening spaced from said first opening, said through-aperture centered on an aperture axis and defining a female profile at said second opening in a plane normal to said aperture axis,
- a first internal chamber,
- a third opening to said first internal chamber, and
- a fourth opening to said first internal chamber spaced from said third opening, said fourth opening surrounding said second opening in the plane;
- and
- a blade having an outwardly-facing male profile at least partially matching said female profile and sized to be received in said through-aperture and also defining a first cutting edge;
- and
- a second member with:
- a first body sized to be received in said through-aperture with said blade, said blade positionable between said first body and said female profile at said second opening,
- a second internal chamber,
- a fifth opening to said second internal chamber, and
- a sixth opening to said second internal chamber spaced from said fifth opening, said sixth opening extending about said aperture axis in the plane with said fourth opening.
