1. A trajectory guide comprising:

  • a first clamp member spaced from a second clamp member;

    a guide body pivotably connected to the first and second clamp members and defining a guiding surface and a brake surface, the brake surface disposed between the first clamp member and the second clamp member, wherein at least one of the first clamp member and the brake surface defines a convex surface engaged against the other of the first clamp member and the brake surface, wherein the first clamp member and the brake surface diverge from a first end toward a second end and the first clamp member rolls against the brake surface along the convex surface;

    a clamp disposed proximate the second end and configured to urge the first clamp member and the second clamp member together at the second end against the brake surface of the guide body and thereby lock the guide body in a selected position; and

    a first engagement surface associated with the first clamp member and a second engagement surface associated with the second clamp member, each engagement surface disposed proximate the first end;

    wherein the first engagement surface separates from the second engagement surface and the first clamp member is simultaneously clamped against the brake surface at the convex surface to lock the guide body in response to the clamp urging the first clamp member and the second clamp member together at the second end.
