Striking assembly and surgical tool assembly
A surgical tool assembly having a striking assembly is disclosed. The surgical tool assembly includes a handle for attachment to a tool, and a striking assembly for attachment to the handle. The striking assembly includes a frame, an impact plate extending from the frame, and a guard attached to the frame and movable between a first position adjacent the frame and a second position. The second position may be distal to the frame, e.g., adjacent the handle.
1. A striking assembly for attachment to a surgical tool, comprising:
a frame;
an impact plate extending from about a proximal end of the frame; and
a guard attached to about a distal end of the frame and movable between a first position adjacent the frame and a second position distal to the frame,
wherein, in the second position, the guard is configured to protect a user's fingers from being struck by a striking tool used to strike the impact plate.
2. The striking assembly of claim 1 , further comprising a lock mechanism for securing the guard in a fixed position relative to the frame.
3. The striking assembly of claim 1 , further comprising an attachment mechanism for attaching to a surgical tool.
4. The striking assembly of claim 1 , wherein the impact plate extends radially outwardly from the frame.
5. The striking assembly of claim 1 , wherein the guard is attached to the same side of the frame that the impact plate extends from, or wherein the guard is attached to an anterior side of the frame.
6. The striking assembly of claim 1 , wherein the frame includes a positioning member having a first and a second positioning slot, and the guard is secured to the frame via the positioning member.
7. The striking assembly of claim 6 , further comprising a lock that includes a keyed locking pin movable relative to the positioning member between an unlocking position and a locking position wherein in the locking position the keyed locking pin engages one of the first or second positioning slots.
8. The striking assembly of claim 7 , wherein the lock further comprises a biasing member biasing the keyed locking pin to the locking position.
9. The striking assembly of claim 1 , wherein the frame further comprises a stop to operatively engage the guard in the second position.
10. The striking assembly of claim 1 , wherein the frame further comprises a biasing actuator to operatively actuate the guard into the second position.
11. The striking assembly of claim 1 , the guard comprising:
a base for attaching to the frame; and
a curved guard body extending from the base, wherein when in the second position, the curved guard body is distally spaced from a distal end of the frame.
12. The striking assembly of claim 11 , wherein the guard further comprises a curved distal end.
13. A surgical tool assembly comprising:
a handle for attachment to a tool; and
a striking assembly for attachment to the handle, the striking assembly including:
a frame,
an impact plate extending from the frame, and
a guard attached to the frame and movable between a first position adjacent the frame and a second position adjacent the handle,
wherein, in the second position, the guard is laterally adjacent a majority of a longitudinal length of the handle and is configured to protect a user's hand from being struck by a striking tool used to strike the impact plate.
14. The surgical tool assembly of claim 13 , wherein in the second position the guard is laterally adjacent the handle.
15. The surgical tool assembly of claim 13 , wherein the guard is attached to an anterior side of the frame.
16. The surgical tool assembly of claim 13 , wherein the handle attaches to a distal end of the striking assembly and a longitudinal axis of the handle is substantially aligned with a longitudinal axis of the frame of the striking assembly.
17. The surgical tool assembly of claim 13 , wherein the striking assembly further comprises an attachment mechanism for attaching to the handle, the attachment mechanism including:
a pair of detents for operatively engaging cooperating detents on the handle.
18. A surgical tool assembly comprising:
a handle for attachment to a tool; and
a striking assembly for attachment to the handle, the striking assembly including:
a frame,
an impact plate extending from the frame and having a longitudinal axis transverse to a longitudinal axis of the frame,
a guard attached to the frame and movable between a first position adjacent the frame and a second position adjacent the handle, and
an attachment mechanism for attaching to the handle.
