No estado atual dos instrumentais cirúrgicos, particularmente os utilizados no campo da medicina veterinária, dedicados a realização de suturas de tecidos em animais, são mais conhecidos e utilizados alguns instrumentais que apresentam pouca praticidade e conforto no uso, tais como: a uma agulha para sutura em forma de "S", que é muito simples; o porta agulha "Mathieu", que é ineficiente, e o porta-agulha "Mayo Hegar", que é utilizado para determinadas aplicações. In the current state of surgical instruments, particularly those used in the field of veterinary medicine, dedicated to performing tissue sutures on animals, some instruments that have little practicality and comfort in use are better known and used, such as: a suture needle S-shaped, which is very simple; the "Mathieu" needle holder, which is inefficient, and the "Mayo Hegar" needle holder, which is used for certain applications.
A agulha em forma de "S" é geralmente utilizada sendo apoiada na palma da mão e forçada contra o tecido a ser suturado. Procedimento que, por ser o tecido biológico trabalhado resistente e flexível (geralmente couro), exige um considerável esforçQ para se efetuar a perfuração e frequentemente acarreta feridas na mão, a qual $ agulha é apoiada, causando desconforto para o cirurgião. The "S" needle is usually used by being held in the palm of the hand and forced against the tissue to be sutured. A procedure that, because the biological tissue is tough and flexible (usually leather), requires considerable effort to perforate and often causes hand wounds, which the needle is supported, causing discomfort to the surgeon.
O porta-agulha "Mathieu" e o porta-agulha "Mayo Hegar" também não são suficientemente práticos para suturas em tecidos biológico^ resistentes e flexíveis, porque não apresentam um apoio especialmente projetado para o tipo de esforço necessário na perfuração destes tecidos. Neste caso, geralmente, no ato da sutura, quando o cirurgião exerce a força necessária para perfurar o tecido, que é resistente, a
agulha tende a deslocar ou quebrar na tentativa de perfuração. The "Mathieu" needle holder and the "Mayo Hegar" needle holder are also not practical enough for sutures in resilient and flexible biological tissues because they do not have a specially designed support for the type of effort required to perforate these tissues. In this case, usually when suturing, when the surgeon exerts the necessary force to pierce the resistant tissue, the Needle tends to shift or break when attempting to puncture.
