    • A brain lead anchoring system is described which allows for installation of a brain stimulation lead or a drug delivery catheter without the lead or catheter ever being unsupported during installation so that the lead or catheter does not move during the anchoring procedure. An anchor assembly contains an anchoring mechanism that is biased in the closed or anchoring position and is only open to allow installation of a lead when it is mated to an introducer instrument, which has prongs that open the anchoring mechanism. Once the lead is appropriately positioned within the brain and while the lead is still supported by the installation guiding device, the introducer instrument is withdrawn from the anchoring mechanism, which thus allows the anchoring mechanism to return to its closed position. A locking cap covers the aperture through the anchor assembly into the skull and mechanically ensures that the anchoring mechanism remains in the closed position. The anchor assembly also has channels in its top surface within which the lead may be inserted so that the lead may be lain flat on the surface of the patient's skull.
    • 描述了一种脑引导锚定系统,其允许安装脑刺激引线或药物递送导管,而不会在安装期间引导或导管不被支撑,使得在锚固过程期间引线或导管不移动。 锚固组件包括锚定机构,该锚固机构在关闭或锚定位置被偏置,并且仅当打开以允许引线安装到具有打开锚定机构的插入件的导引器仪器的导引器仪器时才能安装。 一旦引线被适当地定位在大脑内,并且引线仍然被安装引导装置支撑时,导引器器械将从锚定机构中退出,从而允许锚固机构返回其关闭位置。 锁定盖将穿过锚固组件的孔覆盖到颅骨中并机械地确保锚定机构保持在关闭位置。 锚固组件还在其顶表面中具有通道,在该顶部表面内可以插入引线,使得引线可能在患者头骨的表面上平坦。

    • Generally, the present invention is directed to a method and system for a aligning surgical guide instrument over a burr hole in a patient's body. More particularly, the present invention is directed to a stand-alone instrument guidance unit that is attachable to a patient's skull. Adjustments of a surgical instrument can be made in x, y, z, and angular directions using the system and method of the present invention. In one aspect of the present invention, an instrument guide unit includes an instrument guide for guiding a surgical instrument into the body of a patient and a base unit operative to be secured to the body in an area in which surgery. is to occur. The base unit is coupled to the instrument guide. An adjustment mechanism, coupled to the base unit and the instrument guide, is operative to adjust the instrument guide in lateral directions with respect the surface of the area. The adjustment mechanism is operative to adjust the instrument guide in x and y directions. The adjustment mechanism includes an x direction control mechanism for adjusting the instrument in an x direction and a y direction control mechanism for adjusting the instrument in a y direction. The y direction control mechanism may be coupled to the x direction control mechanism. The positional movement of the surgical instrument in the z direction may be tracked by sensing the location of a transducer coupled to the surgical instrument.
