  • Publication number: 20120136389
    Abstract: A suture lock according to the present invention provides sufficiently secures a suture thread in place in a quick and efficient manner. It eliminates the need for a laproscopic surgeon to tie complex or multi-step knots. The suture lock generally comprises a suture lock body having a suture channel that allows a suture thread to be drawn into the suture lock body. A plurality of teeth extends into an opening of the suture channel in such a manner that an inserted suture thread will be locked in place. In addition, a guide portion eases insertion of a suture thread free end by simplifying relative rotational adjustment of the lock. An embodiment of the present invention may be fabricated from a material or materials that naturally dissolve within the human body.

  • Patent number: 8187301
    Abstract: A suture lock to be used with a suture thread. The suture lock comprises at least one passageway for receiving a suture thread, with the passageway having at least a portion of its length having a longitudinal side opening arranged to slidably receive the suture. The passageway is tapered inwardly and including an interior surface having inwardly converging teeth. The invention may also comprise a suture lock having an adjustable channel located within the suture lock. The channel may be adjusted between an open and a closed position, thereby allowing the suture to be secured. Translation of the suture itself may be utilized to adjust the positioning of the channel. The suture lock may contain a releasable device to retain the channel in multiple positions between the closed and open position.

  • Patent number: 5606920
    Abstract: A table having a horizontally enlarged worksurface, and a pair of leg assemblies fixed to the worksurface directly at the opposite end edges thereof and projecting downwardly for engagement with a floor. Each leg assembly includes an upright leg member disposed directly at the rear corner of the worksurface, and at its lower end this leg is fixed to a horizontally elongate foot which projects forwardly for engagement with the floor. The leg adjacent its upper end has a support bracket which projects forwardly directly under and fixedly secured to the worksurface in close proximity to the end edge thereof. The outer side surfaces of the leg and base are preferably vertically flat and substantially vertically coplanar, and are also substantially vertically coplanar with the end edge of the table. A cable-accommodating trough is fixed to and extends horizontally between the legs in downwardly spaced relation from the rear edge of the worksurface.

  • Patent number: 5601037
    Abstract: A freestanding table having a worksurface supported on height-adjustable legs, each having a height-adjusting mechanism. These mechanisms are simultaneously driven through a driving element such as an endless chain driven by a driving sprocket disposed adjacent the underside of the worksurface. The driving sprocket is nonrotatably connected to a rotatable hub supported in a recess in the worksurface, which recess also accommodates a foldable crank. The crank when in a folded and stored position is disposed in the recess so as to be substantially flush with the upper surface of the worksurface. The crank is pivotally joined about a first axis to an intermediate link which in turn is pivotally joined about a second axis to a rotatable hub so that the crank can be pivoted upwardly through an angle of about 180.degree. so as to be disposed above the worksurface to permit manual gripping and hence rotation thereof when height adjustment is desired.
