Abstract
A rotary surgical assembly is disclosed. The assembly has a plurality of cutting teeth (216), a hollow dome (200) and a spindle (10). The hollow dome has a pole having a pole axis X, and a cutting surface featuring some of the cutting teeth. The cutting surface includes a curved part (214) and a substantially flat part (212) proximal the pole with an aperture (210) extending therethrough. The spindle has a proximal end (12) and a distal end (14) including a spindle mounting element (16). The spindle mounting element is secured to the dome beneath the substantially flat part of the cutting surface. The spindle mounting element has a cutting tooth (22) that extends distally through the cutting surface's aperture to form one of the said plurality of cutting teeth. A kit, and methods of manufacturing the rotary surgical assembly are described also.
