Grampo de Sutura Suture Clamp
Campo do Invento Invention Field
O presente invento refere-se a um grampo de sutura, particularmente baseado na mandíbula da formiga saúva soldado do género Atta. Tal dispositivo foi desenvolvido através da técnica biônica, que estuda os sistemas vivos para descobrir processos, técnicas ou princípios que possam ajudar na criação de projetos. The present invention relates to a suture clamp, particularly based on the welded ant jaw of the Atta genus. This device was developed through the bionic technique, which studies living systems to discover processes, techniques or principles that can help in the creation of projects.
Antecedentes do Invento Background of the Invention
Os métodos de sutura existentes apesar de apresentarem bastante evolução ainda apresentam problemáticas. Na sutura por fios, ainda não existe um fio ideal, pois este seria aquele totalmente inerte a infecção. Além disso, a técnica é traumática e ainda ocorre um trauma maior, principalmente em crianças, por ser bastante demorada e dolorosa. Existing suture methods, despite their considerable evolution, still present problems. In thread suture, there is not yet an ideal thread, as this would be the one totally inert to the infection. In addition, the technique is traumatic and there is still a major trauma, especially in children, because it is very long and painful.
Na sutura por adesivo biológico ocorre o abafamento da ferida, proliferação de bactérias e polimerizante tóxico, evitando a cicatrização com rapidez. Na sutura por grampo metálico, apesar de apresentar vantagens como a execução fácil e rápida causando o mínimo de dano aos tecidos, cicatrização sem dificuldades e não favorecimento de infecção na pele, também apresenta desvantagens, pois a dor dos grampos na sua colocação e retirada é bem maior que aquela resultante dos pontos tradicionais (por fios). Além disso, a sutura por grampo possui um custo mais elevado, sendo o principal motivo a necessidade de um grampeador para assim fixá-lo na pele humana. In biological adhesive suture, there is wound suppression, proliferation of bacteria and toxic polymerizer, preventing rapid healing. In metallic staple suture, despite having advantages such as fast and easy execution causing minimal damage to tissues, healing without difficulties and not favoring skin infection, it also has disadvantages, because the pain of staples in its placement and removal is much larger than that resulting from traditional stitches (by wire). In addition, staple suturing has a higher cost, the main reason being the need for a stapler to fix it on human skin.
Quanto ao estado da técnica de patentes, o documento WO 90/04356, considerado como o estado da técnica mais próximo do invento, descreve um dispositivo para sutura que inclui um par de braços móveis interligados 12 e 14, cada um com pelo menos um membro de inserção na pele 18 e 20 possuindo uma extremidade livre para penetrar a pele na proximidade da região a ser suturada. O dispositivo é móvel de uma posição aberta, onde as extremidades
livres dos membros de inserção estão espaçados uni do outro para a colocação do dispositivo sobre a região a ser suturada, até uma posição fechada, onde os membros de inserção penetram a pele adjacente a região a ser suturada para unir as duas bordas da região para facilitar a cicatrização da mesma, e o dispositivo citado inclui meios para conduzir os braços para a posição fechada. With regard to the state of the art patent WO 90/04356, considered as the closest state of the art of the invention, describes a suture device comprising a pair of interconnected movable arms 12 and 14, each with at least one member inserts 18 and 20 having a free end to penetrate the skin in the vicinity of the region to be sutured. The device is movable from an open position where the ends Free of the insertion members are spaced apart to place the device over the region to be sutured to a closed position where the insertion members penetrate the skin adjacent the region to be sutured to join the two edges of the region to facilitate healing thereof, and said device includes means for guiding the arms to the closed position.

Such a clamp was designed as a single piece and has a connecting flange 3 extending between the clamping areas 1 and 2 and being resiliently elastic.
EP 0 432 743 também é um grampo metálico dotado de pontas, porém em peça única e que se utiliza de força elástica, o dispositivo do documento EP 0 432 743 também não se confunde com o presente invento e, portanto, provavelmente não alcança a melhoria funcional do presente invento conforme relato do inventor. EP 0 432 743 is also a spiked but one-piece metal clamp utilizing tensile strength, the device of EP 0 432 743 also does not confuse the present invention and therefore probably does not achieve improvement. of the present invention as reported by the inventor.
O documento US 3,525,340 apresenta um curativo cirúrgico em que um lado de um substrato relativamente fino, elástico e flexível é fornecido com grampos cirúrgicos para a inserção simplificada do mesmo através do substrato na pele, para coaptação das bordas de lacerações, que pode ser feito pela simples pressão manual sobre os grampos. US 3,525,340 discloses a surgical dressing in which one side of a relatively thin, elastic and flexible substrate is provided with surgical clips for simplified insertion thereof through the substrate into the skin for coaptation of the laceration edges, which can be made by simple manual pressure on the clamps.
US 3,525,340 não ensina como produzir ou mesmo as vantagens do presente invento.
O documento US 2008/0027484 refere-se a um apararelho para assistência e manutenção do fechamento de feridas que pode esticar a pele ao redor da ferida gradualmente até atingir o fechamento da ferida e manter o fechamento da ferida durante o período mais crítico no pós-operatório. US 2008/0027484 em nenhum momento antecipa o presente invento. US 3,525,340 does not teach how to produce or even the advantages of the present invention. US 2008/0027484 refers to a wound closure care and maintenance apparatus that can gradually tighten the skin around the wound until it reaches wound closure and maintain wound closure during the most critical postoperative period. operative. US 2008/0027484 at no time anticipates the present invention.
Um instrumento cirúrgico para a fixação e aplicação de tensão e união das bordas de pele separadas conforme necessário para a sutura de uma ferida é apresentado no documento US 5,843,125. O referido objeto é um instrumento cirúrgico utilizado apenas durante a cirurgia que em nada antecipa o presente invento. A surgical instrument for fixing and applying tension and joining the separated skin edges as needed for suturing a wound is disclosed in US 5,843,125. Said object is a surgical instrument used only during surgery which in no way anticipates the present invention.
Pode-se ver que WO 90/04356 e EP 0 432 743 já descrevem um grampo metálico dotado de pontas, sendo EP 0 432 743 em peça única e se utiliza de força elástica para a realização de suturas. No entanto, em virtude de sua nova forma ou disposição e melhorias técnicas relatadas pelo inventor, o presente grampo de sutura baseado na mandíbula da formiga saúva é inventivo frente aos ensinamentos do estado da técnica. It can be seen that WO 90/04356 and EP 0 432 743 already describe a pronged metal clamp being EP 0 432 743 in one piece and using elastic force for suturing. However, by virtue of its new form or arrangement and technical improvements reported by the inventor, the present ant-jaw-based suture clip is inventive in light of prior art teachings.
