Abstract
A neuro-surgical clamp device that has a semi-circular track that partially circles the patient's head. A C-clamp clamps securing to the patient's head, with the semi-circular track clamped to the C-clamp with a vice-clamp with at least one moving jaw. The C-clamp is coupled to a base bar though a series of three arms and four rotatable joints so that the semi-circular track can be tilted and rotated to any angle with respect to the patient's head. Instrument attaches can be clamped anywhere along the semi-circular track.
Claims18
A neuro-surgical clamp device comprising:
- a C-clamp (201) having a first end and a second end, the C-clamp rotatably attached to a first arm (219) through a first rotating joint (202), the first arm rotatably attached to a second arm (211) through a second rotating joint (208), the second arm rotatably attached to a third arm (216) through a third rotatable joint (207), the third arm rotatably attached to a base bar (200) through a fourth rotatable joint (203), the base bar constructed to be attached to a fixed support;
- the C-clamp having a first head contact (212a) on the first end and a second contact (212b) on the second end, the first and second head contacts constructed to clamp a patients head during cranial surgery;
- a semi-circular accurate track (206) attached to a straight rod (204) through a swivel joint (211), the swivel joint constructed to allow the accurate track to rotate with respect to the straight rod;
- the semi-circular accurate track constructed to partially pass around the patient's head;
- a vice-clamp (205) having a through-hole receiving the straight rod, the vice-clamp having at least one movable jaw, the vice-clamp clamped to the first end of the C-clamp;
- the neuro-surgical clamp device being constructed to tilt and rotate to any angle with respect to the patient's head by adjustment of the swivel joint (211), the vice-clamp (205), the first rotatable joint (202), the second rotatable joint (208), the third rotatable joint (207) and the fourth rotatable joint (203).
A neuro-surgical clamp device of the type used in cranial surgery comprising a semi-circular track (206) attached to a straight rod (204) through a swivel joint (211), the straight rod clamped to a C-clamp (201) with a vice-clamp (209), the C-clamp coupled to a first arm (219) through a first rotatable joint (202), the first arm coupled to a second arm (218) through a second rotatable joint (208), the second arm coupled to a third arm (216) through a third rotatable joint (207), the third arm coupled to a base bar (200) through a fourth rotatable joint (203), the base bar constructed to attach to a fixed support, wherein by adjustment of the swivel joint, the first, second, third and fourth rotatable joints, the semi-circular track can be adjusted to any angle with respect to the C-clamp.
