摘要:
An ultrasonic probe includes a shaft having a longitudinal axis and a head disposed at a distal end of the shaft. The head has a cylindrical lateral surface and an end face oriented perpendicularly to the axis. The head has three shaping surfaces at a distal end of the cylindrical surface, each shaping surface extending at an acute angle to the axis. Each of the shaping surfaces intersects or is contiguous with both the cylindrical surface and the end face.

摘要:
In preparation for a medical procedure utilizing a medical instrument such as a high intensity focused ultrasound probe sterile water is gravity fed to a reservoir container through a hydrophobic hollow fiber or membrane filter connected to a vacuum pump, whereby the reservoir container is filled with degassed sterile water. The reservoir is operatively connected to the medical instrument in a hydraulic circuit through which the degassed sterile water is pumped from the reservoir container. The circuit is purged of air and then closed to render the medical instrument in condition for a medical procedure.

A liquid containment system in accordance with the present invention includes a flexible plastic or elastomeric bag with several apertures. Surrounding each aperture is a port member such as a silastic ring. The port member functions at least reduce the escape of airborne particules from the bag while permitting the insertion of a surgical instrument into the bag. The port member may be made at least partially of a silicone based material to provide resistance to damage by ultrasonic tools.
摘要:
An application includes a variety of metadata and operations that may process the metadata. Selective portions of the metadata are identified and various combinations of available operations are automatically generated for the selective metadata. Each generated operation is then individually validated for syntax and semantics, without actually executing the operation.
