Abstract
The skull clamp system with pressure limiting and alarm systems includes at least one and preferably multiple inwardly power driven immobilizing pins adjustably engaging the skull of a patient. The pin power drive systems includes at least one sensor capable of sensing the degree of back pressure on the pin from contact of the pin against the bone of the patient, the sensor being capable of signaling the drive system to stop when the sensor detects a preselected degree of back pressure. The sensor is also capable of signaling an alarm to warn of any reduction of pressure applied to the pins that might result from pin slippage.
Claims14
A skull clamp system, comprising:
- a skull clamp support having:
- at least one pin, the pin having a distal end, a proximal end, and a central portion disposed therebetween, the distal end being configured to contact the bone of a patient's skull;
- and
- a support clamp connected to the at least one pin;
- a powered drive system connected to the pin, the powered drive system being capable of driving the pin into contact with the bone of a patient's skull;
- and
- at least one sensor in proximity with said pin, the at least one sensor being configured for sensing the degree of back pressure resulting from contact of said pin against the skull of the patient;
- wherein said at least one sensor is capable of transmitting a signal to a computer-controller system, the signal indicating the degree of back pressure on said pin that is sensed as said pin is driven against the bone of the patient's skull;
- wherein said at least one sensor comprises multiple sensors, the multiple sensors being capable of independently providing the signal indicating the degree of back pressure on said pin.
