摘要:
Ultrasonic horns configured for use with a surgical ultrasonic handpiece including a resonator are described. The ultrasonic horns include an elongated member having a longitudinal internal channel extending partially therethrough. Disposed on the distal end of the elongated member is a chisel and awl shaped tip configured for cutting and/or abrading hard tissue, for example bone.

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either device within the brain.

The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interventional devices may be introduced to the area of interest, as well as a variety of treatments. A subsequent treatment process may also be employed.

Holding arrangements for a surgical access assembly are disclosed. One holding arrangement includes a body portion, an engagement barrel and a retaining member. The retaining member is configured as a hook at a distal end of the body portion and is sized to partially encircle a portion of an outer sheath. The engagement barrel is position on a proximal end of the body portion and is configured to be operatively connected to a surgical holding arrangement.

Ultrasonic horns configured for use with a surgical ultrasonic handpiece including a resonator are described. The ultrasonic horns include an elongated member having a longitudinal internal channel extending therethrough. Disposed on the distal end of the elongated member is a tip lead configured for cutting and/or abrading hard tissue, for example bone. The tip lead includes an abrasive surface.

A surgical access assembly is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath is defined by an open distal end and an open proximal end and includes a hollow body portion therebetween. The obturator is defined by a distal end and a proximal end and the distal end further comprises a tapered distal tip member that terminates in a closed radiused distal tip. The obturator is configured to be received within the outer sheath such that the tapered distal tip member protrudes from the open distal end of the outer sheath when the obturator is in an introducing configuration.

Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.
