Abstract
A surgical tool holder aids a surgeon in controlling the use of a tool during, for example, preparation of a femoral cavity for reception of hip joint prosthesis. The holder has a housing that encloses a mechanism having, at a far end, a tool-engaging interface, and at the opposite end, a handle which facilitates manipulation of the tool during use in preparing a bone site by the surgeon. The holder enables easy orientation of the tool attached to its end, which is important because control of the tool is critical in order to accurately prepare a recess for reception and installation of a prosthesis.
Claims20
A surgical tool holder comprising:
- a housing with a grip;
- and
- a linkage chamber at least partially receiving a tool holder linkage, the tool holder linkage fixed to the housing by a linkage lock mechanism, and pivotally affixed at a point in the chamber such that when the linkage lock mechanism is released, the tool holder linkage is pivotable out of the chamber for cleaning.
A surgical tool holder comprising:
- a housing with a grip end, a linkage chamber, and a tool end, the tool end for receiving a tool;
- a tool holder linkage at least partially within the linkage chamber, the tool holder linkage fixed to the housing by a linkage lock mechanism, and pivotally affixed at a point in the chamber such that when the linkage lock mechanism is released, the tool holder linkage is pivotable out of the chamber for cleaning;
- a connecting rod disposed within the linkage chamber, the connecting rod being disposed between the tool end and the grip end;
- a mechanical movement coupling device disposed at the tool end of the connecting rod, the mechanical movement coupling device comprising a pawl to couple the tool to the tool end;
- and
- an engagement lever disposed at the grip end of the connecting rod;
- wherein movement of the engagement lever to a first position moves the pawl into a position to engage the tool end, and wherein movement of the engagement lever to a second position moves the pawl to a position to release the tool end and further to enable remove of at least a substantial portion of the linkage assembly from within the linkage chamber.
A surgical tool holder comprising:
- a housing with a grip end, a linkage chamber, and a tool end, the tool end for receiving a tool;
- a tool holder linkage at least partially within the linkage chamber, the tool holder linkage fixed to the housing by a linkage lock mechanism, and pivotally affixed at a point in the chamber such that when the linkage lock mechanism is released, the tool holder linkage is pivotable out of the chamber for cleaning;
- a relatively rigid connecting rod disposed within the linkage chamber, the connecting rod being disposed between the tool end and the grip end;
- a mechanical movement connector disposed at the tool end of the connecting rod, the mechanical movement connector comprising a pawl to couple the tool to the tool end;
- and
- an over-center latch mechanism disposed at the grip end of the connecting rod;
- wherein the over-center latch mechanism has a first stable position when the tool is coupled to the tool end and a second stable position when the tool is not coupled to the tool end.
