Retractor device with oximeter sensor and force sensor

摘要

A retractor device has an oximeter sensor at its tip, which allows measuring of oxygen saturation of a tissue being retracted by the retractor. The retractor device also has a force sensor which can measure an amount of force that is applied to the retracted tissue by the tip of the retractor device. The tip includes one or more openings for at least one source and detector. A specific implementation is a spinal nerve root retractor with an oximeter sensor and a force sensor.

主权项

1. A device comprising:
a retractor, for retracting a tissue, comprising a shaft, a first member coupled to a proximal end of the shaft, and a tip coupled to a distal end of the shaft, wherein the tip comprises a retractor portion and an oximeter sensor; a force sensor operatively coupled to the retractor via the first member; and a second member, wherein the force sensor comprises a first connection point and a second connection point, and the first connection point of the force sensor is coupled to the first member and the second member is coupled to the second connection point of the force sensor.
