  • Patent number: 9993917
    Abstract: A handgrip for the handle of a cleaning tool, and particularly a push broom, has a frustum shaped front section with side walls tapering downwardly from an outwardly extending upper lip portion to an opening at the terminus of the front section. The opening is shaped to retain the cleaning tool handle. A stock shaped rear section extends downwardly from the front section. The rear section has a curved top wall which merges smoothly downward into curved sidewalls and merges upwards to the lip portion. A curved notch is formed between the lip portion and the top wall. This configuration allows the user to maintain a comfortable grasp of the handgrip, eliminating the strain and risk of injury, while ensuring that the user's hand does not slip off the handle.

  • Patent number: 9198747
    Abstract: A transobturator technique was developed for treating male urinary incontinence. This approach helped to design specific instruments to pass around the ischio-pubic branches of the male pelvis from inside to outside (i.e from the suburethral space to the thigh fold). The inside-out transobturator sling technique uses specific instruments and a polypropylene mesh with two arms that are passed inside to outside through the obturator foramens, pulled for compressing the bulbar urethra upward, and tied to each other across the midline. The mesh passes around the ischio-pubic branch before being tied under the bulbar urethra where it brings tension and support.

    Abstract: A laparo-suture needle and method for use thereof. A medical suturing instrument employs an outer, hollow shaft having a laterally-disposed, elongate handle at a proximal end and an elongate, inner shaft disposed within the outer shaft. The inner shaft has a cutting edge at the distal end and extends out of the outer shaft at the proximal end, terminating in a spring-loaded push button. A lateral notch is formed in the inner shaft proximal of the cutting edge. The spring forces the inner shaft rearwardly so as to pull the notch within the outer shaft. By gripping the handle and placing pressure on the push button, the inner shaft is moved forward so as to expose the notch. A suture may then be placed in the notch so that the instrument grips the suture between the outer shaft and the inner shaft when the push button is released.

  • Patent number: 5613975
    Abstract: A surgical suturing apparatus for closing an incision penetrating a plurality of layers of tissue includes a tubular body in which a "J"-shaped suture needle resides. In this position the tubular body may be inserted into the incision without damaging tissue. Once the tubular body has been inserted into the incision, the pointed end and suture gate of the suture needle are deployable out of a slot through the side of the tubular body to permit deep suturing of tissue layers without also suturing surface tissue layers. Several embodiments are presented for deploying the needle, including one in which the straight section of the suture needle having the pointed tip is biased to flare away from the other straight section of the suture needle, and the deploying is accomplished by moving the pointed tip section adjacent the tubular body slot and permitting the bias to cause that section to flare out of the slot.

    Abstract: A suture device including a hook needle, a body portion which fits within a wound site and a handle portion pivotally attached to the body portion. The needle is J-shaped with a long straight part and short curved part terminating in a pointed end. The long part of the needle slides in a channel in the handle portion and the pointed end moves axially toward and away from the handle with the curved part of the needle facing internal organs during closure of a wound site in an abdominal cavity.

  • Patent number: 5405354
    Abstract: A suture driver for clamping a suture in the hollow passage and a recessed channel thereof and manipulating the suture to and from a surgical site. The driver includes an outer member tube having a closed and pointed distal end for percutaneous introduction into the body of a patient. The outer tube also includes a recessed channel positioned proximal the closed distal end of the hollow passage extending longitudinally therein and for receiving the suture therein. An inner rod is positioned in the passage of the outer tube and has a clamping surface at the distal end thereof for engaging a suture positioned in the recessed channel. The inner rod is slid through the recessed channel to clamp the suture in the hollow passage of the outer tube against another clamping surface at the distal end of the tube.

  • Patent number: 5230352
    Abstract: A single-strike die mechanism includes a rotatable cam drive ring driven to impart through a cam mechanism linear motion to at least three crimping dies. The crimping dies are symmetrically arranged within a die guide and simultaneously actuated to move in a radial direction toward a centerline of a surgical needle. A surgical suture is axially inserted within a hollow barrel end of the needle, and the barrel end is crimped by the crimping dies to secure the suture therein. A method for operating the single-strike die mechanizes the procedure for securing the suture within the barrel end of the needle.

  • Patent number: 5178628
    Abstract: In the production of a suture needle, a distal end portion of an elongated material is ground into a generally quadrangular pyramid shape. Then, the distal end portion of the elongated material is further ground into a generally triangular-pyramid shape, so that the distal or foremost end of the elongated material is positively pointed. The suture needle has four main surfaces and an auxiliary surface. The above triangular-pyramid shape is defined by two of the main surfaces and the auxiliary surface.

  • Patent number: 5129558
    Abstract: A sewing needle has a main body 10 and a closed loop 18 of a resilient filament material rigidly secured to the rear end of the main body and lying a single common plane with the lengthwise axis of the main body. In unstressed condition, the filament has an open diamond configuration allowing a sewing thread to be easily passed through it. As the needle is pulled through the fabric, the loop collapses under the forces imposes on its sides by the fabric and thereafter expands to reassume its unstressed configuration. The rigid securement of the loop to the main body of the needle ensures that the loop remains in a single common plane with the needle axis as it collapses upon passage through the fabric and as it expands to its unstressed configuration following such passage.

  • Patent number: 5038836
    Abstract: The needle has an openable eye and is of use in a lacing stage of a tridimensional weaving of a composite reinforcement element, for driving out rigid rods and replacing them with loops of wire or thread. The needle has an axial aperture (13) at the end of the needle in the vicinity of the eye and the inner end of the aperture (13) is open and connected to the exterior through a passageway (14) which is oblique relative to the axis of the body of the needle (8) and laterally opens out through an orifice (15) in the vicinity of the eye (12), between the eye and the end of the needle.

  • Patent number: 5016383
    Abstract: A fish bait applicator that has a finger grip with a light reflective, textured surface and has a attachment port to attach the applicator to the equipment or clothing of the user. The fingergrip also causes the applicator to float in water. There is a shaft with one end connected to the fingergrip. The shaft has on the other end a hook with a sharpened leading edge. There is a latch means that pivots over the hook to restrict access to the hook and to reduce the change of a leader loop from being dislodged from the hook when the applicator is being pulled back through the bait. There is a recess in the shaft to receive the latch means when the latch means is not in place over the hook. There is a latch means port into which the latch means is pivotally mounted.
