摘要： Hand-held surgical instruments include magnetic couplings which impart simultaneous reciprocal rotary and longitudinal motions or oscillations to a distally located workpiece. In preferred embodiments, the magnetic couplings include a drive shaft, an output shaft coaxially aligned with the drive shaft relative to a central axis, and drive and driven magnet assemblies connected operatively to the drive and output shafts, respectively. The drive and driven magnet assemblies include permanent magnets arranged to translate continuous rotation of the drive shaft into simultaneous rotary and longitudinal movements of the driven magnet assembly relative to the drive axis. A resilient support member exhibiting torsional and longitudinal resiliency (e.g., an annular elastomeric disc) is most preferably operatively connected to the output shaft to allow for such simultaneous rotary and longitudinal movements thereof.

摘要： A hand-held surgical light assembly is provided with a light source, and a handpiece which is adapted to be grasped and manipulated by a user. The handpiece has a light guide with a proximal end optically connected to the light source, and a distal end which projects outwardly from said handpiece so as to direct light guided thereby onto a field of view determined by manipulation of the handpiece by the user. The handpiece includes a switch assembly which is operatively coupled to the light source to allow user selection between at least two different light intensities (e.g., essentially on/off) discharged by said light guide onto the field of view. In preferred forms, the switch assembly includes an electrically conductive inner base member and an electrically conductive outer tubular elastomeric member concentrically positioned in surrounding, but spaced relationship, with the inner base member. When contact between the inner base member and the outer elastomeric member is made, switch circuitry changes the visible light intensity of the visible light generated by the light source, e.g., by either directly modulating the current to the lamp itself, or by providing an electrically operable shutter assembly which masks the light generated by the light source. The former embodiment is especially well suited for surgical lights which are self-contained (i.e., have the light sources contained in the handpiece), while the latter is especially well suited for surgical lights which have remotely positioned light sources.

摘要： Hand-held instruments have an actuator assembly which may be employed to actuate a distally mounted tool by application of radial force about the entirety of the instrument circumference (i.e., is omni-actuatable). Most preferably, the actuator assembly includes a plurality of circumferentially spaced-apart generally L-shaped actuator levers defining respective arcuate bearing surfaces along exterior edge regions thereof, and a retaining ring which circumferentially bounds the actuator levers around the exterior edge regions thereof. The retaining ring most preferably defines an interior stationary arcuate guide surface in conformable mated relationship to the bearing surfaces of said actuator levers. Radial force applied to the proximally extending arm sections of said levers thereby responsively causes the bearing surfaces thereof to be slideably moved along the guide surface of said retaining ring so as to translate such radial force into longitudinal movements of an elongate actuation pin between retracted and extended positions thereof. By providing a tool which operatively coacts with the actuation pin, a surgeon may actuate the tool as needed by applying radial force at any point about the circumference of the actuator assembly.

摘要： Miniature surgical forceps are formed from a one-piece tubular member by opposed longitudinal channels machined in a distal end thereof so as to establish a radially opposed pair of unitary forceps jaws. Most preferably, the opposed channels are formed in the distal end of the rigid tubular member by means of electron discharge machining (EDM) techniques. The resulting opposed cross-sectionally arcuate jaw sections may be bent and/or further shaped to achieve the desired final jaw configuration. The inner surfaces of the forceps jaws thereby established may have a filler material deposited in such a manner so as to change the overall shape and/or geometric configuration of the jaws and thereby engineer them to a specific surgical purpose.

摘要： Surgical instruments, especially for opthalmological surgical procedures, have a smooth, bulbous arcuate tip that surrounds the distal end of a lumen. The tip may be translucent and flexible. Most preferably, the tip is formed of a compliant, yet self-supporting, material, such as medical grade transparent silicone elastomer. The bulbous arcuate tip may take various geometric forms, for example, generally spherical, ellipsoid or the like. The bulbous arcuate tip may be symmetrical about the elongate axis of the instrument or may be asymmetrical (i.e., angularly disposed) relative to such longitudinal axis. The surgical instruments of this invention are most preferably made by first adhering a length of compliant tubing (e.g., silicone) onto a distal end of a rigid tube (e.g., a section of a stainless steel needle). The proximal rigid tube section is preferably coaxially sleeved over, and affixed to, the distal compliant tube section. A forming wire may then be inserted into the aligned lumens of the proximal rigid tube and distal compliant tube sections so that a terminal end section of the forming wire extends beyond the distal end of the compliant tube section. A bolus of curable liquid elastomer is then applied onto the distal end of compliant tube section around the forming wire protruding therefrom. By rotating and otherwise manipulating the tube sections during curing of the liquid elastomer, a bulbous arcuate tip may be formed. Once the elastomer tip is cured (solidified), the forming wire may be withdrawn thereby forming a through lumen which terminates at the tip. The tip may alternatively be constructed using injection-molding techniques.

摘要： Soft tissue examination apparatus and method employ an ultrasonic transducer system for generating a series of ultrasound pulses, at least one of which is of sufficiently high intensity to induce physical displacement of the soft tissue. The transducer receives a series of ultrasonic echo pulses and responsively generates a series of data signals indicative of such tissue displacement. A data processor receives the data signals and determines the magnitude of the displacement. In such a manner, the present invention assists in the evaluation and/or diagnosis of biological tissue. Preferably, the apparatus and method of this invention is employed to examine the properties of a subject's vitreous body and thus may be used in the evaluation and/or diagnosis of ocular disorders, such as vitreous traction.

摘要： Disclosed herein are systems and method for segmentation and identification of structured features in images. According to an aspect, a method may include representing an image as a graph of nodes connected together by edges. For example, the image may be an ocular image showing layered structures or other features of the retina. The method may also include adding, to the graph, nodes adjacent to nodes along first and second sides of the graph. The added nodes may have edge weights less than the nodes along the first and second sides of the graph. Further, the method may include assigning start and end points to any of the added nodes along the first and second sides, respectively. The method may also include graph cutting between the start and end points for identifying a feature in the image.
