Abstract[English]
The present invention discloses a medical stapler designed for efficient wound closure, utilizing a four-legged staple assembly. The staple assembly comprises four symmetrically positioned legs—two longer or standard legs for engaging deeper tissue layers and two shorter legs for securing superficial skin layers—each configured to penetrate tissue at an angle of approximately 90 degrees ± 15 degrees relative to the tissue surface. The staple is formed as a continuous, one-piece biocompatible metallic structure with a central apex that uniformly distributes compression forces across the wound site. This design enables simultaneous closure of multiple tissue depths in a single deployment, enhancing surgical efficiency. The symmetrical leg spacing ensures even tissue engagement, while the configuration resists rotational movement within tissue, improving post-deployment stability.[French]
La présente invention divulgue une agrafeuse médicale conçue pour une fermeture de plaie efficace, utilisant un ensemble d'agrafe à quatre pattes. L'ensemble d'agrafe comprend quatre pattes positionnées de manière symétrique, deux pattes plus longues ou standard pour venir en prise avec des couches de tissus plus profondes et deux pattes plus courtes pour fixer les couches cutanées superficielles, chacune étant conçue pour pénétrer dans le tissu selon un angle d'environ 90 degrés ± 15 degrés par rapport à la surface du tissu. L'agrafe est formée sous la forme d’une structure métallique biocompatible monobloc continue présentant un sommet central qui répartit uniformément les forces de compression sur le site de la plaie. Cette conception permet la fermeture simultanée de multiples profondeurs de tissu en un seul déploiement, améliorant ainsi l'efficacité chirurgicale. L'espacement symétrique des pattes garantit un engagement uniforme des tissus, tandis que la configuration résiste au mouvement de rotation à l'intérieur du tissu, améliorant la stabilité après déploiement.
