Surgical healing of tendon division
Lately during surgical healing of tendon division, the main suture approximates using atraumatic serpentine needle. Our company started serial producing atraumatic needles for serpentine sutures of tendons by analogy with needle Tsuge.
Two ends of threads are molded into a tail-end of needle. Our company produces threads and needles such sizes USP: 4/0 for tendons of deep flexor and extensor muscle of fingers for children, 3/0- for tendons of deep flexor and extensor muscle of fingers for adults, 2 - for Achilles' tendon. The last needle is used also for recovering patellar ligament and sewing patella in case of its breaking.
Diameter of an original needle Tsuge and our manufactured needle differs from traditional cutting needle. In the original needle a sharp edge locates on a concave side. That’s why it is called convex-concave. In needles Tsuge and “Volot” the sharp edge locates on an arched side. Such needles are called arched-cutting or back cutting needle. During using back cutting needles in a tissue of a tendon after pricking forms a triangular wound. A base of a “wound triangle” is directed to a tightened thread and it prevent from its eruption. The traditional needle also forms a triangular wound but in this case the top of a needle (which cut onto a threads) is directed to a thread. Hence the tissue put by traditional cutting needle to a greater extent traumatizes a tendon than special needles.
