  • Patent number: 10456127
    Abstract: An assembly and method for the protection of medical personnel from accidental suture needle sticks is described. The assembly includes a case containing a needle which can be retracted when not in use. The needle is extended and retracted through the engagement of a needle driver which compresses a compressible member. The compressible member exerts a force on the needle which in turn extends the needle's point beyond the casing so that the user can suture tissue. Disengaging the needle driver retracts the needle point which protects the user from accidentally receiving a needle prick from a contaminated needle between punctures.

  • Patent number: 5676675
    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.

  • Patent number: 5503634
    Abstract: A device and method are provided for the surgical suturing of narrow incisions that penetrate through a plurality of tissue layers. An elongated, "J"-shaped needle, through which suture material is threaded, is inserted into the wound, bringing the tip through one or more layers of tissue on one side of the wound and pulling suture material up through the wound. After repeating these steps on the other side of the wound, the suture material is knotted. A slidable locking member serves the dual purpose of covering the tip of the suture needle when not in use and also of maintaining pneumoperitoneum.

  • 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.
