Spinal surgery is carried out under direct visualication through a relatively small opening (72) formed in a patient~s skin (74). Intervening tissue (76) between the opening (72) and the surgical site is displaced so as to form a keyhole channel therethrough. The channel is characterized in that it increases in width as it progresses from the opening (72) to the surgical field (78). The use of the keyhole channel maximizes the surgeon~s access to the surgical field (78) while minimizing tissue trauma. Also disclosed are surgical retractors (10) used to provide the channel.
La chirurgie spinale est effectuée avec visualisation directe par un orifice (72) relativement petit formé dans la peau (74) d'un patient. Le tissu (76) situé entre l'orifice (72) et le site chirurgical est déplacé de manière à former un canal. Ce canal est caractérisé en ce que sa largeur va en augmentant de l'orifice (72) jusqu'au champ chirurgical (78). L'utilisation du canal maximise l'accès du chirurgien au champ chirurgical (78) tout en réduisant au minimum la lésion tissulaire. L'invention concerne également des écarteurs chirurgicaux (10) permettant de former le canal.
