Skull clamp system with pressure limiting and alarm systems
First Claim
Patent Images
1. 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 a bone of a patient'"'"'s skull;
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 the pin, the at least one sensor being configured for sensing the degree of back pressure resulting from contact of the pin against the skull of the patient, the sensor further configured for sensing a sudden decrease in pressure due to an imminent break through or fracture of the skull.

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.
