Surgical cement removal tool
A surgical cement removal tool including an elongated shaft having a proximal end and a distal end, and a bowl-shaped scoop affixed to the distal end. Handle attachment structure can be provided adjacent the proximal end of the elongated shaft to permit releasable attachment of the surgical cement removal tool to a handle. Alternatively, the proximal end of the elongated shaft may be permanently affixed to a suitable handle.
1 . A surgical cement removal tool comprising:
a bowl-shaped scoop having a notchless, longitudinally continuously convex exterior surface and a proximally directed interior open side;
an elongated shaft having a proximal end and a distal end, the distal end of the elongated shaft being affixed to the interior open side of the bowl-shaped scoop.
2 . The surgical cement removal tool of claim 1 , wherein the bowl-shaped scoop is concentrically arranged with respect to a central longitudinal axis of the elongated shaft.
3 . The surgical cement removal tool of claim 1 , wherein the open side of the bowl-shaped scoop has a proximal end including a cutting edge about a perimeter thereof.
4 . The surgical cement removal tool of claim 3 , wherein the cutting edge extends 360 degrees about the perimeter of the proximal end of the open side.
5 . The surgical cement removal tool of claim 3 , wherein the cutting edge is contiguous with a sloped surface disposed at an acute angle with respect a central longitudinal axis of the elongated shaft.
6 . The surgical cement removal tool of claim 1 , further comprising handle attachment structure adjacent the proximal end of the elongated shaft for enabling releasable attachment of the surgical cement removal tool to a handle.
7 . The surgical cement removal tool of claim 1 , further comprising a handle connected to the proximal end of the elongated shaft.
8 . The surgical cement removal tool of claim 7 , wherein the proximal end of the elongated shaft is fixedly connected to the handle.
9 . The surgical cement removal tool of claim 7 , wherein a circumference of the elongated shaft is sized to be received within a slot of a slotted hammer, whereby the hammer is used to strike a distal end of the handle and exert proximally directed force on the handle.
10 . The surgical cement removal tool of claim 1 , wherein the proximally directed open side has a single concave interior surface therein.
11 . The surgical cement removal tool of claim 10 , wherein the concave interior and convex exterior surfaces are each concentrically arranged with a central longitudinal axis of the elongated shaft.
12 . The surgical cement removal tool of claim 10 , wherein the bowl-shaped scoop has a proximal end including a cutting edge about a complete perimeter thereof.
13 . A surgical cement removal tool comprising:
an elongated shaft having a proximal end and a distal end; and
a bowl-shaped scoop affixed to the distal end of the elongated shaft, wherein the bowl-shaped scoop:
has an uninterrupted and distally directed, relative to the elongated shaft, convex exterior surface over an entire hemispheric shape thereof;
has a proximally directed open side relative to the elongated shaft, the open side having a single concave interior surface therein; and
the concave interior and convex exterior surfaces are each concentrically arranged with a longitudinal axis of the elongated shaft.
14 . The surgical cement removal tool of claim 13 , wherein the bowl-shaped scoop has a proximal end including a cutting edge about a perimeter thereof.
15 . The surgical cement removal tool of claim 14 , wherein the cutting edge extends 360 degrees about the perimeter of the proximal end of the bowl-shaped scoop.
16 . The surgical cement removal tool of claim 14 , wherein the cutting edge is contiguous with a sloped surface disposed at an acute angle with respect to the longitudinal axis of the elongated shaft.
17 . The surgical cement removal tool of claim 13 , further comprising a handle attachment structure adjacent the proximal end of the elongated shaft for enabling releasable attachment of a handle of the surgical cement removal tool.
18 . The surgical cement removal tool of claim 17 , wherein the handle attachment structure includes at least one radially projecting key sized to be received in a correspondingly-shaped opening provided in a distal end of the handle, to releasably lock the elongated shaft to the handle.
19 . A surgical cement removal tool comprising:
an elongated shaft having a proximal end and a distal end; and
a bowl-shaped scoop affixed to the distal end of the elongated shaft, wherein the bowl-shaped scoop:
has a convex exterior surface over an entire hemispheric shape thereof;
has a proximally directed open side relative to the elongated shaft, the open side having a shaped interior surface therein; and
the shaped interior and convex exterior surfaces each have an apex located at a longitudinal axis of the elongated shaft.
20 . The surgical cement removal tool of claim 19 , wherein the convex exterior surface of the bowl-shaped scoop is uninterrupted and continuous over the entire hemispheric shape thereof.
