Interlocking surgical staple assembly
First Claim
1. A skin opening and closure device for surgical procedures, comprising:
- (a) first and second elongated locking strips having mating strip locking means formed along the length thereof, said locking strips being capable of interlocking assembly and capable of being separated and reassembled;
(b) a plurality of spaced half-staple means being secured to each of said locking strips and being in closely spaced relation along the length thereof, said half-staple means each defining arcuately curved skin penetrating portions having point means inclined angularly toward one another and adapted to be embedded into the skin of a patient in preparation for surgery, said skin penetration portions being preformed with bending sections such that deformation of said half-staple means by staple installation apparatus at said bending sections causes said arcuately curved skin penetrating portions and said point means to penetrate the skin, traverse an arcuate path deeply into the skin tissue such that said point means are positioned immediately beneath the surface of the skin and adjacent the incision line; and
(c) with said half-staple means embedded in the skin of the patient, said locking strips being separatable to expose the skin of the patient to permit incision and capable of being forced into interlocking assembly to close the incision and bring the skin tissue at the incision into tightly abutting relation.

Abstract
A skin opening and closure device for surgical procedures incorporates elongated flexible locking strips having elongated locking means formed thereon which is adapted to be placed in interlocking assembly and capable of being separated and relocked, as desired. A plurality of half staples are provided, each of which is partially embedded within respective ones of the locking strips to thereby define staple assemblies. The half-staples incorporate curved, hook-like skin penetrating elements which retain the locking strips in positive hooked assembly with the skin to prevent inadvertent staple separation when the locking strips are separated. The half-staples are adapted to be bent intermediate the extremities thereof to establish a secure skin retaining relation with the skin of the patient to provide a secure closure at the surgical incision. In use, the half-staples of the device are brought into engaging assembly with the skin of the patient at the site of the intended incision. Thereafter, the locking strips are separated in zipper-like manner to expose the skin for incision. After completion of the surgical procedure, the locking strips are brought into interlocked relation by manual pressure or by zipper-like closure means to close the incision.

8. A skin opening and closure device for surgical procedures, comprising:
-
(a) first and second elongated locking strips capable of being placed in interlocking assembly and capable of being separated and relocked; (b) a plurality of half-staple means being secured to each of said locking strips and being closely spaced along the length thereof, said half-staple means each defining elongated staple bar means positioned in generally coextensive relation, said staple bar means each defining bending points positioned in spaced relation with one another and positioned immediately adjacent the respective elongated locking strip; and (c) arcuately curved skin penetrating elements extending from each of said staple bar means and defining sharp skin penetrating points integral therewith and at the free extremities thereof, said skin penetrating elements being of hook-like configuration with said free extremities thereof being positioned in arcuate angular relation with said staple bar means and positioned in converging relation with one another, upon deformation of said half-staple means at said bending points, said skin penetrating points penetrating the skin of the patient and traversing an arcuate path through the skin and sub-skin tissue of the patient, bringing the opposed skin penetrating points close together immediately beneath the surface of the skin and adjacent to an intended incision line.
