NEEDLE WITH INTEGRATED FIBERS
First Claim
1. A needle (100, 300, 400) comprising:
- a tip part (200, 310) comprising a through bore in axial direction,a holder part (160, 360, 460) comprising an opening,a shaft (110) comprising an inner tube (352) and an outer tube (350), wherein distal ends of the inner and outer tubes are connected with the tip part (200, 310), and proximal ends of the inner and outer tubes are connected with the holder part (160, 360, 460), and wherein a space (356) is formed between the inner tube and the outer tube,a fiber (130, 230, 240, 250, 330, 340), the fiber being capable of transmitting light, wherein an end section of the fiber is located in the through bore of the tip part (200, 310), wherein the fiber is located in the space (356) formed by the inner and outer tubes of the shaft (110), and wherein the fiber passes through the opening of the holder part.

Abstract
Needles equipped with fibres allow tissue inspection based on optical spectroscopy to diagnose whether tissue is cancerous or not. This requires integration of optical fibers into needles. The problem is how to manufacture the needle having at least one fiber exit at the distal end of the needle, where the fiber does not obstruct the hollow part of the needle if present as well as does not extend beyond the outer cylinder geometry. To solve this problem we propose to manufacture the needle consisting of four parts: an inner cylinder tube, an outer hollow cylinder tube, a needle tip part with integrated fiber exit and a holder part, wherein the hollow spacing between the inner and the outer cylinder is larger or equal to the outer diameter of the fibers, the inner and the outer cylinder are mounted in the holder part and where the tip part is mounted on the two cylinders.
