Surgical device and surgical method
First Claim
1. A surgical instrument system for ophthalmic surgery in an interior of an eye, comprising:
- an OCT apparatus including an interferometer;
an optical fiber coupled to the OCT apparatus and extending a probe arm of the interferometer, the optical fiber having a tip end;
a hand tool comprising;
a hand piece,a tube extending away from the hand piece and comprising a distal end portion having a longitudinal axis and a tip end, wherein a distal portion of the optical fiber is received within the tube;
a beam emitter coupled to the tip end of the optical fiber and configured to emit an OCT measuring beam into an emission direction of the beam emitter; and
an actuator configured to change the emission direction of the OCT measuring beam relative to the tip end of the distal end portion;
wherein a first tangent to the longitudinal axis at a proximal end of the distal end portion and a second tangent to the longitudinal axis at the tip end of the distal end portion form a bending angle of the distal end portion of between 60 and 100 degrees; and
wherein a first distance between an intersection point of the first tangent with the second tangent and the proximal end is between 4.5 mm and 8 mm; and
wherein a second distance between the intersection point and the tip end of the distal end portion is between 3 mm and 9 mm.
