The present device relates to a retractor assembly for minimally invasive surgery, comprising: a main body which is inserted through an opening of a patient, has a channel formed therein, and of which both ends are penetrated and a tip unit which is provided on the distal end of the main body, and of which the edge of the end portion is formed to correspond to the shape of the outline of the patients bone which is the part subject to surgery. Thus, the retractor assembly for minimally invasive surgery is capable of stable and reliable surgery without touching sensitive and dangerous parts such as body fluid tubes through which body fluids flow, blood vessels, and ligaments.Le dispositif de la présente invention concerne un ensemble écarteur pour chirurgie mini-invasive, comprenant : un corps principal qui est introduit à travers une ouverture pratiquée chez un patient, qui présente un canal percé à lintérieur et dont les deux extrémités sont traversantes et une unité de pointe qui est prévue sur lextrémité distale du corps principal, et dont le bord de la partie terminale est conçu de façon à correspondre à la forme du contour de los du patient devant faire lobjet de lintervention chirurgicale. Ainsi, lensemble écarteur pour chirurgie mini-invasive permet une intervention chirurgicale constante et fiable ne touchant pas les parties sensibles et dangereuses telles que les conduits de fluides corporels à travers lesquels sécoulent les fluides corporels, les vaisseaux sanguins et les ligaments.본 고안은 피시술자의 개구(opening)를 통하여 삽입되며, 내부에 채널(channel)이 형성된 양단 관통의 본체 및 상기 본체의 선단(distal end)에 구비되고, 단부 가장자리는 시술 대상 부위인 피시술자의 뼈의 외곽 형상에 대응되게 형성되는 팁 유닛을 포함하는 것을 특징으로 하여, 체액이 흐르는 체액관이나 혈관 또는 인대 등과 같은 민감하고 위험한 부위를 건드리지 않고 안정적이면서도 확실한 시술이 가능하도록 한 최소 침습 시술용 리트랙터 어셈블리에 관한 것이다.
