SYSTEM WITH PHOTONIC BIOPSY DEVICE FOR OBTAINING PATHOLOGICAL INFORMATION

摘要

A biopsy device is provided comprising a tubular member, a hollow shaft and an elongated fiber body. The hollow shaft may have a distal end and a shaft, wherein a laterally (sidewardly) facing notch is formed in the distal portion of the shaft. The elongated fiber body may include at least one optical fiber, preferably at least two optical fibers, with a distal end. The tubular member is movable relative to the shaft, between a first position in which the notch is covered by the tubular member, and a second position in which the notch is not covered by the tubular member. The fiber body is movable within the shaft, between a first position in which the distal end of the optical fiber is located at the distal end of the shaft with the elongated fiber body extending through the notch, and a second position in which the distal end of the at least one optical fiber is located proximally to the notch.

1. A system for obtaining pathological information, including
a biopsy device comprising a tubular member, a hollow shaft, the shaft having a distal end, wherein a sidewardly facing notch is formed in the shaft adjacent the distal end of the shaft, wherein the shaft is movably accommodated within the tubular member, and an elongated fiber body including at least one optical fiber, the optical fiber having a distal end, wherein the fiber body is accommodated within the hollow shaft, wherein the tubular member is movable between a first position in which the notch is covered by the tubular member, and a second position in which the notch is not covered by the tubular member, and wherein the hollow shaft is movable between a first position in which the distal end of the optical fiber is located at the distal end of the shaft with the elongated fiber body extending through the notch, and a second position in which the distal end of the at least one optical fiber is located proximally to the notch.
