Dental filing tool handle

摘要

An improved handle for a dental filing tool, the tool having an arcuate handle with a horizontal bridge and opposed first and second vertical arms, the improvement including first and second sets of partial-cylindrical grip portions distributed along the outer surfaces of the first and second vertical arms, respectively, the grip portions aligned normal to the handle plane, the respective first and second sets defining convex or concave outer grip profiles and concave front-back grip profiles. An improved handle may further include an embedded socket to receive a coupler for a dental driver, or a projecting coupling to engage a dental driver coupling.

1. An improved handle for a dental filing tool, the tool having an arcuate handle with a horizontal bridge and opposed first and second vertical arms extending from opposite ends of the bridge to terminal ends, the vertical arms and bridge having outer surfaces and being adapted to hold a filing strip extending between them, the horizontal bridge and vertical arms generally defining a handle plane and having a front surface and a back surface, the improvement comprising:
first and second sets of partial-cylindrical grip portions distributed along the outer surfaces of the first and second vertical arms, respectively, each of the grip portions extending longitudinally from a first end surface projected outward from the handle front surface to a second end surface projected outward from the handle back surface, each of the grip portions aligned longitudinally normal to the handle plane; each set comprising a first grip portion disposed proximate the vertical arm terminal end, a second grip portion disposed proximate the connection region of the bridge and respective vertical arm, and a plurality of spaced-apart interstitial grip portions distributed between the first and second grip portions; and, a projecting coupler having a first part embedded within the handle first arm and a second part extending outward from the handle first arm, the second part comprising a dental driver coupling.
