1465998 Wound closing appliances C E KAWCHITCH 10 Dec 1974 [10 Dec 1973] 53412/74 Heading A5R A surgical appliance to close surgical incisions comprises an elongate, flexible tape 11, Fig. 1, and an elongate spring 12, Fig. 2, the tape comprising a flat strip 13 with parallel projecting ribs 14 providing a V-shaped channel which defines a course for an incision, the spring 12 comprising a single length of resilient wire bent to provide two sets of longitudinally aligned straight side portions 26 interconnected by connecting portions 27 of generally channel shape the spring being of an open ended channel shape, the straight side portions of one set being staggered relative to those of the other set, and the connecting portions 27 being successively oppositely inclined to the longitudinal direction of the spring gaps 28 being provided between portions 26, the spring being applicable to tape 11 by applicator (33), Fig. 3 (not shown) to enable ribs 14 to project into the spring and be clasped between the two sets of straight side portions 26 which engage laterally outwardly facing channels 19. Connecting portions 27 of spring 12 include V-shaped tongues 32 engaging within channel 18 in tape 11 when the' two members close an incision. Since in the relaxed condition the channel mouth between portions 26 is narrower than the distance between the sides 21 of channels 19, the spring will hold the ribs together when applicator (33) is removed. To provide a firm closure a thread 31 is tied between eyes 29 terminating the two spring ends and tightened to apply longitudinal compression. The strip underface is coated with a film 24 of biocompatible adhesive protected by a tear-off cover 25. The tape, of e.g. silicon rubber, tapers in thickness towards the side edges 20 and is perforated at 22 and additionally at 22A to provide weakness lines to facilitate separation of sections. In an alternative embodiment, Fig. 7, a flap 41 formed integrally with the wider of two ribs 14A is swung onto flat rims 42 of the ribs, its outer edge flange 49 engaging one rim 42 while its solid central tongue 51 enters a channel 43 between the ribs which contains a V-shaped groove 47 defining a course for the incision. After closing flap 41 a spring 12 is applied as before. In a further embodiment, Fig. 9 (not shown) ribs (14B) of equal width both have flaps (50) with tongues (52) fitting together in the channel between the ribs. A V-shaped tongue (53) on one flap fits into a similar groove (54) in the other to lock the flaps together. |
