Surgical instruments which have multiple functions used in performing endoscopic surgeries, including arthroscopic surgery. Surgical instrument (10) includes a mechanical cutting portion, such as a rotary blade or burr (130), and an electronic cutting and/or cauterizing portion comprising an electronic surgical device which operates in bipolar mode. This solves the problem of having to constantly remove and insert various surgical instruments into the surgery site in order to remove different kinds of tissues and at different rates and in different manners. Rotary burr (130) works best to remove hard tissues, such as bone, while bipolar device (134) can be used to cut or ablate soft tissues and/or cauterize tissue, including blood vessels. Alternatively, the mechanical cutting portion may include a rotary blade, which works best for removing soft tissues.

Instruments chirurgicaux à fonctions multiples, utilisés pour réaliser des interventions chirurgicales endoscopiques, notamment arthroscopiques. L'instrument chirurgical (10) comprend une partie de coupe mécanique, telle qu'une lame ou une fraise rotative (130), et une partie de coupe et/ou de cautérisation électronique, qui comporte un dispositif chirurgical électronique fonctionnant en mode bipolaire. Cela résout le problème lié à la nécessité d'avoir à enlever et à introduire constamment différents instruments chirurgicaux dans le site d'intervention afin d'enlever différentes sortes de tissus, à différentes vitesses et de différentes manières. La fraise rotative (130) est plus efficace pour enlever les tissus durs, tels que l'os, tandis que le dispositif bipolaire (134) peut être utilisé pour couper ou enlever des tissus mous et/ou cautériser des tissus, notamment les vaisseaux sanguins. La partie de coupe mécanique peut également comporter une lame rotative, qui est plus efficace pour enlever les tissus mous.
