Guided saw with pins
First Claim
1. A system for resecting a femoral bone, the system comprising:
- at least two pins for insertion into the femoral bone;
a cutting device having a cutting element adapted to resect bone to form a planar surface; and
, a link adapted to connect to the at least two pins to the cutting device, wherein the link is adapted to constrain movement of the cutting device;
whereby the cutting device is permitted to be moved in a manner that causes the cutting element to resect the femoral bone to form a planar resection on a femoral bone without the need for a cutting guide.

Abstract
Embodiments of improved systems and processes for cutting bones. Embodiments of improved systems and processes for resecting a femoral bone are provided, the system comprising a guiding device adapted to be connected to the femoral bone, a cutting device having a cutting element adapted to resect bone, and a link adapted to connect to the guiding device to the cutting device, wherein the link is adapted to constrain movement of the cutting device. Embodiments of improved systems and processes for cutting knee bones during computer assisted knee surgery are provided, comprising at least one fiducial associated with the guiding device and a tracking functionality capable of tracking a position and orientation of the at least one fiducial.

6. A process for resecting a femoral bone, comprising the steps of:
-
inserting at least two pins into the femoral bone;
providing a cutting device having a cutting element adapted to resect the femoral bone to form a planar surface; and
,linking the at least two pins and the cutting device with a link adapted to connect to the at least two pins to the cutting device, wherein the link is adapted to constrain movement of the cutting device; and
,moving the cutting device in a manner that causes the cutting element to resect the femoral bone to form a planar resection on the femoral bone without the need for a cutting guide. - View Dependent Claims (7, 8, 9, 10)

11. A system for resecting a femoral bone using minimally invasive surgical techniques, the system comprising:
-
a guiding block adapted to be connected to a medial surface of the femoral bone, the guiding block comprising at least one guiding feature corresponding generally to at least one resection to be formed on the femoral bone;
a cutting device having a cutting element adapted to resect bone to form at least one planar surface;
at least one cooperating structure connected to the cutting device adapted to track the at least one guiding feature on the guiding block;
whereby the cutting device is adapted to be utilized to form at least one resection on the femoral bone corresponding to the at least one guide feature on the guiding block, when the cutting device is manipulated in a manner that allows the cooperating structure to track the at least one guiding feature. - View Dependent Claims (12, 13, 14, 15, 16, 17)
