摘要： A method and apparatus for periodically interrupting ultrasonic power applied to a ultrasonically vibrating tip to control its amplitude between high and low or zero amplitudes with a selectible duty cycle and repetition rate provides enhanced fragmentation and improves surgical control. The duty cycle may also vary as a function of a remotely sensed parameter such as tissue temperature.

摘要： Smoke detection apparatus including a pair of photoelectric cells which receive illumination selectively from a very low level light source. One of the cells is termed the "direct" cell because it is in the direct path or on the axis of a narrow conical beam of light emanating from the source, the other cell being termed the "reflected" cell because it receives a significant part of its light input upon reflection of light from smoke particles or the like as such particles are drawn into the path of the light beam. Under predetermined smoke conditions, i.e., when there is smoke obscuration of the light of 2% per foot (.01 optical density), an alarm signal is triggered. The very low level light source is a light-emitting diode which sensitively monitors the smoke obscuration; only a slight change in the illumination to the pair of photocells, connected in a sensing circuit, is required to produce the triggering signal. Accordingly, the smoke detection apparatus is highly sensitive to the presence of either so called "white" smoke or "black", i.e. non-reflective smoke, and either or both will trigger the alarm signal.
摘要翻译：烟雾检测装置包括从非常低级的光源选择性地接收照明的一对光电单元。其中一个单元被称为“直接”单元，因为它处于从源发出的窄锥形光束的直接路径或轴上，另一个单元被称为“反射”单元，因为它接收到重要部分当来自烟粒子等的光反射时，其光输入，因为这样的颗粒被吸入光束的路径。在预定的烟雾条件下，即当每英尺2％的光（.01光密度）存在烟雾遮蔽时，触发报警信号。非常低级的光源是一种发光二极管，可以灵敏地监测烟雾遮蔽; 需要在感测电路中连接的对一对光电池的照明的轻微变化来产生触发信号。因此，烟雾检测装置对所谓的“白色”烟或“黑色”即非反射烟的存在高度敏感，并且两者或两者都将触发报警信号。

摘要： A bipolar electrosurgical device includes a handle and an elongated end effector coupled to the handle. The end effector includes an elongated, insulating body having first and second electrodes disposed thereon. The first and second electrodes are separated at the distal end of the insulating body, and a cavity formed in the distal end of the effector is positioned between the first and second electrodes. A fluid-delivery tube is positioned on the body to deliver a conductive fluid to the distal end, adjacent the cavity. During use of the electrosurgical device, delivery of the conductive fluid facilitates formation of an electrical coupling between the electrodes via the tissue being treated.

摘要： A cutting device for tissue separation includes a cutting edge using electrical energy such as RF power that is coupled to, but thermally insulated from, a catheter in an elongated medical device. Thermal insulation between a ring-type cutting device and the catheter is provided by a gap, slots within the ring, and/or slanted slots within the ring. In one embodiment, tissue separation occurs by rotation of a ring-type electrically-powered cutting edge having internal cross-bar elements. In an alternate embodiment, tissue separation occurs by longitudinal movement of an offset electrically-powered cutting edge that is pressed against tissue by an inflatable balloon. In a further alternate embodiment, a cutting edge is coupled longitudinally to a catheter, is provided electrical energy by wired connection to the braided catheter, but is thermally isolated from the catheter.

摘要： An ultrasonic surgical aspirator having an improved irrigation/aspiration manifold and components to facilitate quick connections of the irrigation and aspiration lines to a handpiece. In combination with a handle assembly having an ultrasonic vibrator for vibrating an ultrasonic tip and a nosecone, a nosecone extension defining a rotating joint for connection to the nosecone in an articulating joint for connection to a rigid or flexible flue is provided. The nosecone extension further defines an irrigation cowl having an irrigation port for receiving an irrigation connector for connecting the irrigation fluid to the nosecone extension for passage of irrigation fluid through the nosecone extension and a flue about the surgical tip. An aspiration tubulation connector adapted to securely fit a slot through the nosecone and nosecone extension connects an aspiration port on the tip to the aspiration tube for connection to a pump into a discard area. An alternative manifold assembly includes a nosecone extension adapter defining a rotating joint for connection to the nosecone in a cylindrical portion for connection to an extender sheath, the opposite end of which is connected to a flue adapter defining an articulating joint for connection to a flue. Such an alternative manifold assembly is particularly adapted for use in elongated and curved tips with extenders. The detailed structure of the aspiration tubular connector and the irrigation connector is also shown.
