First Claim
1. Apparatus for adjusting stereotactically and endoscopically located equipment, comprising;
- a ball having a channel for insertion of medical instruments;
a holder including a lower ring for receiving the ball for universal positioning adjustment about a central ball fulcrum, and an upper ring for locking the ball in a specific position, the lower ring having an external threaded surface for direct screwing to an area of a patient'"'"'s cranium;
a fixing key for securing the lower ring to the cranium; and

Abstract
The invention concerns a device for adjusting stereotactically and endoscopically located equipment, including pharmaceutical agents, radiation sources and organic material, comprising a holder and a fixing key, where the holder comprises a lower ring (1) for receiving a ball (2) which will form a ball joint, and an upper ring (3) for locking the ball in a specific position, where the ball (2) has a channel for insertion of medical instruments, and where the lower ring (1) has an external threaded surface (8) for direct screwing to an area of a patient'"'"'s skull. The device is characterized by the fact that the ball'"'"'s (2) central point, and thereby the ball joint'"'"'s fulcrum is arranged for positioning on a level with the patient'"'"'s cranium by way of a groove-like or curved surface (21) on the holder which forms an abutment for the ball (2). The invention also concerns a method for adjusting different stereotactically and endoscopically located equipment, including pharmaceutical agents, by means of the device, and application of the method in different contexts.
