Surgical Head Clamp and Robotics Platform

A surgical head clamp and robotics platform for securing a head of a patient and positioning an instrument relative to the head of the patient for a medical procedure, the head clamp and robotics platform comprising:

• a planar C-shaped frame for at least partially encircling the head of a patient, the frame including
• a first arm member,
• a second aim member, the second aim member connected at one end to an end of the first arm member in a telescoping relationship for selectively adjusting the distance between the free ends of the first and second arm members,
• a mounting bracket at each of the free ends of the first arm member and the second arm member, the brackets extending away from the first and second arm members in a direction transverse to the plane of the frame, each bracket defining an opening, and
• a pin for engaging the head of the patient and movably received in each of the openings of the brackets, the pin adapted to adjustably extend toward the head of the patient for securing the head of the patient in the head clamp;
• and
• an instrument arm mounted to a free distal end of one of the first arm member or the second arm member, the instrument arm extending away from the one of the first arm member or the second arm member in a direction transverse to the plane of the frame, the instrument arm including
• a base mounted to the one of the first arm member or the second arm member for 360° movement relative to the frame,
• a proximal portion extending from and pivotally connected to the base for rotation relative to the base,
• an intermediate portion extending from and pivotally connected to the proximal portion for rotation relative to the proximal portion, and
• a distal instrument holder extending from and pivotally connected to the intermediate portion for rotation relative to the intermediate portion,
• wherein the instrument arm functions to selectively position the instrument in an angular position relative to the head clamp.

• a base mounted to the one of the first arm member or the second arm member for movement along three degrees of freedom relative to the frame,
• an elongated arcuate instrument holder, and
• a motor interconnected between the base and the instrument holder, the motor configured for rotating the instrument holder about an axis passing through the motor and for axially translating the instrument holder such that the instrument holder is positioned relative to the base between the proximal end of the instrument holder and the distal end of the instrument holder,
• wherein the instrument arm functions to selectively position the instrument in an angular position relative to the head clamp.

• an instrument holder mounted to the track for axially translating along the track between the ends of the first and second arm members,
• wherein the instrument arm functions to selectively position the instrument in an angular position relative to the head clamp.
