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. Additionally, the design minimizes the risk of skin overlap, puckering, and tissue misalignment, supporting a more aesthetically pleasing wound closure.
