The Brown-Roberts-Wells are system is a non-target-centered design, i.e., without an independent approach angle. The approach angle of this system strictly depends on precalculated values (entry and target point). Therefore, some components of the system used sometimes prevent a direct insight into the operation field. Once the entry point has been set, the are system normally has to be taken off to permit an unimpeded approach to the burr here. To facilitate rotation and return to the primary beta and gamma angular settings during stereotactic craniotomy and other surgery, a pair of clamps was designed for the BRW are system. These clamps help the approach to the entry point in such a way that some components of the are (e.g., the guide block holder) are removed from the surgical field, thus giving wide visual access for the stereotactic approach. Consequently, it is no longer necessary to remove the entire are system, resulting in an increased operation safety and shorter operation times.
