摘要:
A surgical system for cytoreducing a brain tumor, the system comprising: a surgical cutting instrument (22) that includes: an internal element (56) that includes a distal cutting tip (112) defining a first tubular surface (92) around of a first central axis (122) and a first distal surface (90) extending from the first tubular surface, the first distal surface being conical in shape and extending from the first tubular surface at a first angle with respect to a first distal axis (96) perpendicular to the first central axis; and wherein the distal cutting tip includes an opening (116) in the first distal surface, said opening being defined by a kidney shape having two semicircular ends connected by two arched portions, the two arched wall portions (120c, 120d) are defined by a central axis (122) of the cutting tip (112) an external element (52) having a distal region that forms a cutting window (70) defined by a kidney shape having two semicircular ends (76a, 76b) connected by two arcuate portions (76c, 76d), the distal region defining a second tubular surface around a second central axis and a second distal surface extending from the second tubular surface; wherein the second distal surface has a conical shape forming a tip (94) and extending from the second tubular surface at a second angle with respect to a second distal axis perpendicular to the first central axis, the cutting window being formed in said second distal surface such that an arcuate portion (76c) is closer to the tip (94) than the second arcuate portion (76d) in which the two arched wall portions (76c, 76d) are defined around a central axis (78) of the distal region (66); a handle (32) that holds the internal and external elements in such a way that the internal element is rotatably received within the external element, the cutting tip being exposed in the cutting window, in which the cutting tip and the distal region combine to define a cutting implement; a suction control device (34) held by the h
