SURGICAL ROTARY ABRADER

摘要

Apparatus for use as a surgical handpiece is disclosed. An exemplary apparatus includes a body 400, a rotatable shaft 220 extending from the body 400 and including a tissue contacting component such as a burr 200, and an outer tube 100 connected to the body and surrounding at least a portion of the shaft 200. In some configurations, the minimum separation between the tissue contacting component and the outer tube 100 is greater than the minimum separation between the shaft 220 and the outer tube 100, thereby preventing the tissue contacting component from contacting the shaft 220 upon the application of a force perpendicular to the axis of the shaft 220. The device 1 may include stand-off elements 700 positioned between the shaft 220 and the outer tube 100 to aid in preventing the tissue contacting component from contacting the outer tube 100 during operation. The outer tube 100 may be flexible with respect to the body 400, such as by being constructed of a relatively flexible material and/or by being flexibly connected to the body 400. In some embodiments, the outer tube 100 may be more flexible than the shaft with respect to the body.
