摘要： A rotatable surgical shaver handpiece having a rotating elongated inner member within a fixed outer member is provided with a means for varying the cutting window orientation of the outer tubular member. The window orientation is adjusted by providing a rotatable collet assembly which has a hollow, outer, longitudinally movable body to which the outer hub member is keyed. The outer collet member is concentrically situated about an inner collet body and is fixed to an annular, toothed locking surface which is movably biased against an identical toothed locking surface fixed to the inner collet body. The teeth have sloped sides and are shallow such that the pre-loaded force compressing the two locking surfaces together is easily overcome by rotating the outer collet body to cause the teeth of one locking surface to slide along the teeth of the mating locking surface. In another embodiment, the invention is provided with a blade recognition means for identifying a code associated with a particular blade assembly regardless of the window orientation of the outer tubular member of the blade assembly. In another embodiment of the invention the handpiece is provided with an extruded body fitted with a longitudinally slidable aspiration control switch.

摘要： An endoscope includes a disposable probe and a non-disposable focusing ocular. The probe includes a transfer module assembly including one or more relay modules, and an objective element including a distal glass window, a molded plastic prism and three molded plastic lenses. Each of the relay modules contains an entry glass rod, an intermediate glass rod, and an exit rod, each having flat end surfaces and two identical molded plastic doublets. The elements of the ocular are all of glass and include an axially movable focusing doublet and two non-movable doublets. The disposable probe introduces certain aberrations into the image. The non-disposable focusing ocular corrects these aberrations. A single curved surface is formed on the distal glass window of the probe; all other curved optical surfaces of the disposable probe are formed on molded plastic members, thereby reducing the cost of the probe sufficiently to be cost-effective for single patient, disposable use.

摘要： A suturing needle is illustrated which can engage a suture to an outer housing, thereby presenting a relatively smooth surface at the distal end of the apparatus to minimize tissue trauma. A lock feature prevents unexpected extension of the needle from the outer housing which could release the suture. A finger switch is used to overcome the locking mechanism when it is desired to release the suture. The distal end of the housing and the needle are a generally similar flat profile to minimize uneven edges which could damage the tissue. The suture is retained in a hook located in the needle, the opening for which is retracted in the housing to retain the suture.

摘要： A single size, universal-type container capable of receiving any one of a variety of elongated medical devices such as rotatable arthroscopic shaver blades, drills, pins, wires and the like. The container has a generally trapezoidal transverse cross-section tapering inwardly from an open end at which a cover or lid may be heat-sealed. The trapezoidal shape enables the container to receive elongated cylindrical devices having different diameters. The container is provided with a pair of longitudinally spaced locking stations, each provided with a plurality of opposed arcuate wall sections for engaging opposite sides of the elongated medical device. The arcuate wall sections of each locking station vary in size from the bottom opening of the container such that the smallest diameter elongated medical devices are retained deep within the container while the largest diameter medical devices are retained closer to the opening of the container. A pair of laterally spaced trigger tabs are molded on the outside of the top wall of the container. The peripheral container wall interconnects the arcuate wall sections to the trigger tab associated with that section such that squeezing the tabs opens the gap between the arcuate wall sections to release the device.

摘要： An improved endoscope employing phase conjugate imaging principles includes a first transmissive member for transmitting light rays received at a distal tip of the endoscope to an intermediate filter location. A phase conjugate filter at the intermediate filter location redirects the rays, according to the precise inverse of their incoming direction, along a second transmissive member optically identical to the first. Rays exiting the endoscope bear the exact relation to one another as when entering the tip of the endoscope and may be imaged or displayed on an eyepiece or video screen.

摘要： A motor-driven surgical instrument having particular use in arthroscopic procedures has its drive motor operation controllable entirely from a switch cluster mounted on the instrument handpiece. The switch cluster is curved to substantially follow the circumferential profile of the handpiece and thereby avoid large platforms or projections that would add to the weight and bulk of the handpiece and destroy its balance. The switches in the cluster are arranged to minimize the movement of a surgeon's finger in quickly moving from a speed or direction control switch to an on/off switch. A unique arcuate printed circuit board having a small radius of curvature is employed as part of the switch cluster and is able to withstand the high temperatures to which the handpiece is exposed during sterilization between procedures. Disposable, single-use cutting blades are individually coded to provide a sensible parameter representing the optimum operating speed range of the cutting blade. This parameter is sensed by the handpiece to provide a control signal which both establishes the optimum motor speed range and provides a visible indication of the established range. In this manner the instrument is able to avoid relatively heavy coded adapters employed in the prior art to provide interface between the cutting blade and the handpiece.

摘要翻译： 具有特别用于关节镜手术的电动手术器械的驱动电动机操作完全可以从安装在仪器手持件上的开关群集控制。 开关簇弯曲以基本上跟随手持件的圆周轮廓，从而避免大的平台或突起，这将增加手持件的重量和体积并破坏其平衡。 集群中的开关被布置成使得外科医生的手指在从速度或方向控制开关快速移动到开/关开关时的移动最小化。 采用具有小曲率半径的独特的弓形印刷电路板作为开关组的一部分，并且能够承受在手术之间的灭菌期间手持件暴露的高温。 一次性一次性切割刀片被单独编码，以提供表示切割刀片的最佳操作速度范围的明智参数。 该参数由手持件检测，以提供一个控制信号，两者都建立最佳电机速度范围，并提供已建立范围的可见指示。 以这种方式，仪器能够避免现有技术中使用的相对较重的编码适配器，以提供切割刀片和手持件之间的界面。
