a saddle (70) adapted to securely hold a medical device, the saddle (70) being placed on said body member (10) and having at least one grip (74, 75, 76) that extends into said at least one groove (60, 62) so as to mount the saddle (70) on the body member (10) moveable in said longitudinal direction; and a means for maneuvering said body member (10). ## Claims ### Claim 1 A surgical apparatus for localizing and treating a lesion in a brain, comprising: a body member having an anterior end, a posterior end and two grooves, one groove of the two grooves on each of two opposite longitudinal outer faces of the body member and extending in a longitudinal direction of the body member between said anterior end and said posterior end; a saddle adapted to securely hold a medical device, the saddle being placed on said body member and having two grips, one grip of the two grips on each of two opposite longitudinal inner faces of the saddle, where each grip extends into a respective groove and is formed with a corresponding shape, so as to fit form locking into said respecive groove to securely mount the saddle on the body member by sliding in said longitudinal direction, and wherein said saddle comprises an open or closed cylinder adapted for mounting a medical device, or a combination of an open and a closed cylinder, a bottom side of the cylinder being formed by an arch comprising an outer shape that reproduces an arched outer shape of the body member; and a handle connected to a neck, the neck comprising a vertical arm and a horizontal arm, for maneuvering said body member. ### Claim 2 (depends on 1) The surgical apparatus according to claim 1, wherein said two grooves comprise an inner shape and said two grips comprise an outer shape, and wherein said inner shape and said outer shape are form-locking with respect to each other and are slidingly supported on one another. ### Claim 3 (depends on 2) The surgical apparatus according to claim 2, wherein said inner shape and said outer shape form an undercut and monovariant connection between said at least one groove and said at least one grip. ### Claim 4 (depends on 1) The surgical apparatus according to claim 1, wherein said two grooves comprise a block at its end facing the posterior end of the body member. ### Claim 5 (depends on 4) The surgical apparatus according to claim 4, wherein the body member is wider on the posterior end than on the anterior end. ### Claim 6 (depends on 1) The surgical apparatus according to claim 1, wherein the at two grooves comprise an insert opening at a front face of the posterior end. ### Claim 7 (depends on 6) The surgical apparatus according to claim 6, wherein the body member is wider On the posterior end than on the anterior end. ### Claim 8 (depends on 1) The surgical apparatus according to claim 1, wherein in case said saddle comprises an open cylinder, said open cylinder has two wings spaced apart by said arch, the wings having free ends that form an opening of the open cylinder for insertion of a medical device, said opening extending in the longitudinal direction. ### Claim 9 (depends on 8) The surgical apparatus according to claim 8, wherein said arch and said wings form a receptacle for a medical device, said receptacle having an inner and/or outer contour adapted to an inner and/or outer contour of a medical device to be mounted in the open cylinder. ### Claim 10 (depends on 1) The surgical apparatus according to claim 1, wherein said neck connecting the handle with the body element, the vertical arm having a proximal part connecting to the body element, and the horizontal arm having a distal part connecting to the handle. ### Claim 11 (depends on 10) The surgical apparatus according to claim 10, wherein said handle comprises reflection balls for optical navigation and/or electromagnetic sensors for electromagnetic navigation. ### Claim 12 (depends on 11) The surgical apparatus according to claim 11, wherein the handle is mounted on a flexible arm adapted to be fixed to a stationary device. ### Claim 13 (depends on 12) The surgical device, according to claim 12, wherein a proximal part of the flexible arm is connected or fixed to the handle by means of at least one proximal clamp, and wherein a distal part of the flexible arm is connected or fixed to the stationary device by means of at least one distal clamp. ### Claim 14 (depends on 10) The surgical apparatus according to claim 10, wherein the handle is mounted on a flexible arm adapted to be fixed to a stationary device. ### Claim 15 (depends on 14) The surgical apparatus according to claim 14, wherein a proximal part of the flexible arm is connected or fixed to the handle by means of at least one proximal clamp, and wherein a distal part of the flexible arm is connected or fixed to the stationary device by means of at least one distal clamp.
