NCT01705821

Brief Summary

This study is designed to measure forces applied using standard surgical instruments at the skull base during resection of skull base lesions. This data will be useful for optimizing an active canula robot for assisting in skull base surgery. We hypothesize that through measurement of forces generated during routine endoscopic skull base surgery we will be able to optimize the canulas of an active canula robot for skull base surgery.

Outcome Measures

Primary Outcomes (1)

  • 6-axis force and torque data from routine endoscopic transnasal skull base surgery

    This data will be collected and recorded via a computer interface with our sensorized tool and recorded in standard units for force and torque. We will also look at the variability of forces between patients after collecting this data. The data will be useful in optimizing a robotic system for endonasal surgery as described in the secondary outcome measure.

    12 months

Secondary Outcomes (1)

  • Percent tumor removal in skull and cadaver studies

Study Arms (1)

Skull Base Surgery Candidate

Patient with a skull base lesion will undergo use of standard surgical curette with force sensor built into shaft. 6-axis force and torque data will be collected during the surgical procedure.

Device: Use of force sensing surgical curetteProcedure: Removal of pituitary tumor using modified curette

Interventions

Use of a standard surgical curette outfitted with an in-line 6-axis force and torque transducer for collection of force data during surgery.
