What changed

The USPTO granted patent US12588912B2 to Stryker European Operations Holdings LLC for a surgical saw with an oscillating head and coupling assembly for releasably holding a saw blade. The patent describes a method of navigating the surgical saw using a navigation processor that tracks a pointer touched against reference points on the saw blade to determine angular orientation and position of the blade relative to the saw. The patent contains 18 claims and covers CPC classifications related to surgical saws and surgical navigation systems (A61B 17/14, A61B 34/20).

This is a routine patent grant announcement with no compliance obligations.

Abstract

A method of navigating a surgical saw with a navigation system having a navigation processor. The method comprising attaching a saw blade to a head of the surgical saw and determining a position of the surgical saw. The method also comprises touching a tracked pointer to one or more reference points on the saw blade and tracking the position and orientation of the tracked pointer as the tracked pointer is touched to the one or more reference points on the saw blade. The method further comprises determining an angular orientation of the saw blade based on the tracked pointer and the one or more reference points on the saw blade, and the navigation system determining the position and orientation of the saw blade relative to saw based on the position and orientation of the saw, the angular orientation of the saw blade, and a characteristic of the saw blade.
