    摘要： An ultrasonic surgical instrument includes a body such as a handle assembly and an acoustic transmission assembly. The acoustic transmission assembly includes an ultrasonic transducer and an end effector. A mounting ring is positioned on a horn of the transducer. A rotatable drum is positioned distal to the mounting ring. Piezoelectric components of the transducer are positioned proximal to the mounting ring. Electrical conduits extend from the drum to the piezoelectric components and are routed over or through the mounting ring. The drum is coupled with a power source through a slip ring assembly to selectively activate the transducer.

    摘要： An optical fiber for use with a laser device including a source of light energy, as well as a method of making such optical fiber, where the optical fiber has a proximal end in communication with the light source and a diffuser portion positionable at a treatment site. The optical fiber includes: a core having a proximal portion, a distal portion and a distal face proximate the diffuser portion of the optical fiber; a layer of cladding radially surrounding the core from the core proximal portion to a point adjacent the core distal portion; a layer of optical coupling material radially surrounding at least a portion of the core distal portion; a slug including a light-scattering material therein positioned adjacent the distal face of the core and a distal end of the optical coupling layer, wherein the light-scattering material fluoresces in a temperature dependent manner upon being stimulated by light; and, a sleeve radially surrounding the cladding layer, the optical coupling layer and the slug, wherein the sleeve is composed essentially of a predetermined type of material; wherein the light-scattering material of the slug is molded with substantially the same type of material utilized for the sleeve.
