South Korea made a scalpel that cuts with plasma — zero blood, zero stitches, just perfect surgical precision

In a development that sounds closer to science fiction than reality, researchers in South Korea have engineered a surgical scalpel that uses plasma instead of metal blades. Unlike traditional scalpels that slice through tissue and leave open wounds, this device creates a fine, high-energy plasma stream that parts tissue while instantly sealing blood vessels. The result is surgery with almost no bleeding and no need for stitches.

The plasma scalpel works by ionizing gas into a controlled stream of plasma, which transfers energy precisely into tissue. Instead of tearing through cells, it separates them cleanly at the molecular level. At the same time, the heat generated by the plasma seals microvessels, creating a bloodless surgical field. For surgeons, this means greater visibility, faster procedures, and far fewer complications.

Another major advantage is that the incision closes itself, eliminating the need for sutures or staples. By avoiding foreign materials in the healing process, recovery becomes smoother and the risk of infection is reduced dramatically. For patients, this means faster healing times, less scarring, and a much lower chance of post-surgery complications.

The technology could revolutionize delicate operations such as neurosurgery, cardiovascular surgery, and organ transplants, where even a small amount of bleeding can mean life or death. Plasma surgery allows doctors to cut with incredible precision while protecting surrounding tissue — something that has never been possible with conventional tools.

South Korea’s medical community is already testing this technology in controlled hospital environments, and the results are promising. Unlike lasers, which can damage surrounding areas with heat, plasma cuts are sharp and controlled, creating a perfect middle ground between accuracy and safety.

If scaled for global use, plasma scalpels could replace the steel blade in operating rooms forever. They mark a turning point in surgery — moving from cutting and stitching to sealing and healing in a single step.

韓國研發出一款等離子手術刀－零出血、零縫合，完美精準的手術精準度

韓國研究人員研發出一款手術刀，它使用等離子而非金屬刀片，聽起來更像是科幻小說而非現實。與傳統的手術刀切割組織並留下開放性傷口不同，該裝置能夠產生細小的高能量等離子流，在分離組織的同時立即封閉血管。手術幾乎不出血，也無需縫合。

等離子手術刀的工作原理是將氣體電離成受控的等離子流，將能量精準地傳遞到組織中。它不是撕裂細胞，而是在分子層面上將細胞徹底分離。同時，等離子產生的熱量會封閉微血管，形成無血的手術區域。對外科醫生來說，這意味著更清晰的視野、更快的手術速度和更少的併發症。

另一個主要優點是切口可自行閉合，無需縫線或釘合釘。由於避免了異物在癒合過程中進入，術後恢復更加順暢，感染風險也顯著降低。對於患者而言，這意味著更快的癒合時間、更少的疤痕以及更低的術後併發症發生率。

這項技術可能會徹底改變神經外科、心血管外科和器官移植等精細手術，在這些手術中，即使是少量的出血也可能關乎生死。等離子手術使醫生能夠以驚人的精確度進行切割，同時保護周圍組織——這是傳統工具從未實現過的。

韓國醫學界已在受控的醫院環境中測試這項技術，結果令人鼓舞。與可能因熱量損傷周圍組織的雷射不同，等離子切割鋒利且可控，在準確性和安全性之間實現了完美的平衡。

如果能夠在全球推廣使用，等離子手術刀將永遠取代手術室中的鋼刀片。它們標誌著外科手術的轉折點——從切割縫合到縫合癒合，只需一步即可完成。
