We want to make possible a new avenue of laser surgery: 'burst mode' ultrashort-pulse laser pulses delivered by nextgeneration fiber-optic tools -- surgery with only a small incision, very fine control of a laser scalpel, and complete control of good and bad heating. This would be an ideal new tool in the trend of minimally invasive surgery using natural openings in the body (natural orifice transluminal endoscopic surgery ('NOTES')). Lasers already offer surgical tools that cauterize, cut or scrape, but modern applications in engineering and in manufacturing are far wider and more sophisticated than has yet appeared in medicine. Ultrafast laser pulses already have a huge medical and commercial impact, e.g., replacing specialized scalpels that open the cornea in LASIK vision-correction surgery. However, not all lasers are the same, and they have to be adapted specifically for the properties of the tissue needing surgery: bone, cornea, cartilage, etc. We want to draw from the pool of brand-new possibilities, to develop for joint surgery a refined kind of very short pulse laser, which delivers 'machine-gun bursts' of pulses, delivered over a new class of optical-fibers, to give a new kind of subtle control: more gentle cutting, faster cutting, better control of depth of cutting, more deliberate management of pain and a wider range of management of the good and bad impact on tissue adjacent to the surgical site, to reduce unnecessary damage while at the same time improving healing.

我们希望开辟激光手术的新途径：下一代提供的“突发模式”超短脉冲激光脉冲 光纤工具——只需一个小切口即可进行手术，对激光手术刀进行非常精细的控制，并完全控制 加热的好坏。这将是利用自然开口的微创手术趋势中理想的新工具。 身体（自然孔腔内窥镜手术（“注释”））。激光器已经提供了可以烧灼、切割或切割的手术工具 刮，但现代工程和制造中的应用比以前更广泛、更复杂 出现在医学上。超快激光脉冲已经产生了巨大的医疗和商业影响，例如取代专门的激光脉冲 在 LASIK 视力矫正手术中打开角膜的手术刀。然而，并非所有激光器都是相同的，它们必须是相同的 专门针对需要手术的组织的特性进行了调整：骨、角膜、软骨等。 我们希望从全新的可能性中汲取灵感，为关节手术开发一种精致的极短脉冲激光， 它通过新型光纤传递“机关枪爆发”的脉冲，从而提供一种新型的微妙 控制：更轻柔的切割、更快的切割、更好的切割深度控制、更刻意的疼痛管理和 更广泛地管理对手术部位邻近组织的好坏影响，以减少不必要的影响 伤害，同时提高治疗效果。
