Abstract
Abstract A method for low trauma suturing: (a) Thin steel needle put into flesh (using a tool) on one side of the wound until anchor fixed to a needle engages flesh. At that time point of needle will protrude. Anchor crimped on the protruding side; (b) Anchors are in ball form with square cavities to accept projections on hand tool; (c) Plier-like tool used to grab anchors has projection which fits into anchor cavities; and (d) dispenser for needle/anchor assembly and dispenser for crimp-on anchor provide for quick removal in sterilized condition.

The method of suturing a cut on the human body comprising the steps of: providing a tool with a pair of pivoted arms having square, facing projections respectively on ends of the arms, the arms to be gripped by the hand and moved so as to move the projections toward or away from one another; providing an arcuately shaped needle with one end being pointed and the opposite end having a first anchor which has a pair of oppositely disposed, square cavities to respectively receive said projections; providing a second anchor with square, opposed, co-axial cavities extending inwardly with one cavity extending inwardly to a greater depth than the other cavity with a barrier between the cavities, the cavities to receive said square projections and the second anchor also having opposed coaxial apertures open to said cavity of greater depth; manipulating said tool to place said projections in said cavities of said first anchor; manipulating said tool to insert on side of the cut said pointed end of the needle into and through the body until the pointed end protrudes from the body on opposite sides of the cut and said first anchor engages the body and thence remove said projections from said cavities of said first anchor; manipulating said tool to place said projections in the cavities of said second anchor; manipulating said tool to cause the apertures in the second anchor to slide over said pointed end of the needle until the second anchor engages said body; and manipulating said tool to cause said barrier to fracture and bend part of the needle into said cavity of greater depth whereby to crimp the needle and second anchor together and thence to remove said projections from said cavities of the second anchor.
