Compressor distractor tool
View Patent ↗A combined compressor and distractor tool is provided that includes a mechanism capable of switching the mode of operation of the tool from a compression tool to a distraction tool. The tool includes engagement tips and handles at opposed ends of the tool that are pivotally connected to a central shaft. A saddle is slidably mounted on the shaft between and pivotally connected to the handles. When the saddle is engaged with the shaft in a before center position, squeezing the handles results the movement of the shaft forwardly to operate the engagement tips as a distractor. However, when the saddle is engaged with the shaft in a past, or over center position, squeezing the handles results the movement of the shaft rearwardly to operate the engagement tips as a compressor.
1. A combination compression/distraction tool comprising:
a) a saddle including a channel formed therein;
b) at least one tip member movably secured to one side of the saddle;
c) a pair of handle members movably secured to the saddle opposite the at least one tip member; and
d) a locking mechanism engaged between the pair of handle members, the locking mechanism including a locking shaft movably secured to one of the pair of handle members and a locking tab movably secured to the other handle member and engaged with the locking shaft wherein the locking shaft is slidably engaged within an aperture formed in the locking tab, further comprising a biasing member disposed between the locking tab and the handle member to which the locking tab is secured to bias the tab into engagement with the locking shaft.
2. The tool of claim 1 wherein the biasing member is disposed around a portion of the locking shaft extending between the locking tab and the handle member to which the locking tab is secured.
3. The tool of claim 1 wherein the locking shaft extends through an opening in the handle to which the locking tab is secured.
4. The tool of claim 1 wherein the locking shaft is frictionally engaged by the locking tab.
