摘要： An improved vitrectomy probe for removing vitreous and other fibrous gel materials. A hollow cutting blade is reciprocated within a smooth bore hollow needle of the microsurgical vitrectomy probe across a cutting edge of the outer needle slicing the fibrous material of the vitreous. A pressurized fluid source, diaphragm and spring cooperate to provide for the reciprocation of the blade. A vacuum source removes vitreous material through the hollow needle. A reciprocating suction outlet tube attached to the hollow needle directs vitreous material into a vacuum fitting which is isolated from the motion of the reciprocating outlet tube. An adjustment screw limits the travel of the reciprocating blade as well as the size of the opening in the needle. A dissector head faciitates the separation of vitreous fibers and directs them into the needle opening.

摘要： A footswitch apparatus for remotely controlling a surgical instrument. The footswitch apparatus preferably includes a base and a footpedal movably mounted to the base. The footpedal is movable within set upward and downward limits. In one mode of operation, the downward travel of the footpedal is resisted by different springs and different ranges of travel. The footpedal position is sensed and the operation of the surgical instrument is altered depending on which of the ranges the footpedal is in. This gives the operator constant tactile feedback as to which range of travel the footpedal is in. In addition, in a second mode of operation, the multiple springs are decoupled and only a single spring is experienced throughout the range of travel. This provides a flexibility so that the same footswitch apparatus can be used to operate a surgical instrument in a particular mode with linear control throughout the range of footpedal travel.
摘要翻译：一种用于远程控制外科器械的脚踏开关装置。脚踏开关装置优选地包括可移动地安装到基座的基座和脚踏板。脚凳可在设定的上下限范围内移动。在一种操作模式中，脚蹬的向下行程由不同的弹簧和不同的行程范围抵抗。脚踏位置被检测，并且手术器械的操作取决于脚踏板的哪一个范围而改变。这给予操作者针脚脚踏板行程的不间断的触觉反馈。此外，在第二模式的操作，多个弹簧被解耦，并且在整个行程范围内仅经历单个弹簧。这提供了灵活性，使得相同的脚踏开关装置可以用于以特定模式操作手术器械，并且在脚踏行程的整个范围内具有线性控制。

摘要： An apparatus for providing counteracting force to overcome the off-center weight of a microscope assembly without counterweights. The apparatus is a microscope balance compensator which uses springs or gas pistons to compensate for a change in a moment developed in a microscope assembly when attachments are added or removed or when the tilt angle of the microscope is changed. The microscope balance compensator includes one device for applying counteracting force about a tilt axis and another device for applying counteracting force about a tip axis oriented perpendicular to the tilt axis. Each counteracting force is applied at discrete angles relative to the pivot centers and is adjustable. The apparatus provides balance compensation over a wide range without adding counterweight, thereby minimizing the total weight of the microscope.
摘要翻译：一种用于提供抵抗力以克服显微镜组件的偏心重量而不具有配重的装置。该装置是显微平衡补偿器，其使用弹簧或气体活塞来补偿当附加物被添加或移除时或当显微镜的倾斜角度改变时在显微镜组件中产生的时刻的变化。显微镜平衡补偿器包括一个用于对倾斜轴施加反作用力的装置，另一装置用于围绕垂直于倾斜轴定向的尖端轴施加反作用力。每个反作用力相对于枢轴中心以离散角度施加，并且是可调节的。该装置在宽范围内提供平衡补偿，而不添加配重，从而最小化显微镜的总重量。

摘要： A phacoemulsification transducer or probe utilizing ultrasonic frequencies to treat cataracts, including a rotatable handle to facilitate repositioning of the needle in the eye during surgery while maintaining a comfortable and secure grip on the instrument. The rotatable handle is comprised of a sleeve portion, irrigation tube and connector member. The sleeve portion is secured to the front of the main body of the probe and the connector member is attached to the distal end thereof.
