Problems solved by technology

[0006] The disadvantage of this known solution is that, on the one hand, the outcoupling (Lichtauskopplung) from the thinner distal-side laser conductor end is not isotropic, but is strongly focused towards the distal end.
Furthermore, the known technical solutions are relatively complex and expensive, so they cannot be used as disposable items for single-use applications

Embodiment Construction

[0071] figure 1 The phototheater system 1 is shown, which has a phototheater operating unit 3 and a replaceable phototheater 5. The phototheater 5 consists essentially of the flexible cable portion 7, which extends from the cutting portion 9 from the proximal side to the distal end side 11. Compared to the cable portion 7, the insertion portion 11 is a component of the phototheater 5 for piercing into the organic tissue of the body 13. Here, the phototheater 5 is suitable for transdermal PDT and is shown in the PDT operation. The insertion portion 11 is configured as a rigid needle portion, for example, in a CT or ultrasound assist with the skin 13 through the patient from the outside from the outside with a health tissue 15 underwater, a health tissue 15 in it. (Eg, malignant tumor) 17.

[0072] The insertion portion or the needle portion 11 has an LED 19 having a distal side on the distal side tip for the activation light of the in-situ generated PDT. For example, if chlorine E...

Abstract

The present disclosure relates to a light treatment device (5) for examining and / or treating an organism, where the light treatment device (5) has a minimally invasive rigid, semi-flexible or flexible insertion portion (11) extending along a longitudinal direction (L) and having an LED (19) at a distal end thereof, where the light treatment device (5) has a first electrical conductor (61a) for powering the LED (19), the first electrical conductor extends in the insertion portion (11) in the longitudinal direction (L) and there has a cross-sectional area that is at least 70% of the cross-sectional area of the light treatment device (5), the light treatment device (5) being thermally isolated in the insertion portion (11) in the radial direction such that the radial thermal isolation decreases towards the proximal end.

Description

Technical field [0001] The present disclosure relates to a phototheater for an examination and / or treatment of an organism, particularly a photodynamic treatment (PDT) for pathological tissue. Background technique [0002] It is well known that using endoscopes is used to shoot interior of the human or animal body for medical diagnosis and / or treatment. The continuous effort is required herein is to design as much endoscopic inserts as possible in order to be able to see as small cavities as much as possible and affect the organization as little as possible. [0003] However, endoscopes are not only used for image or video shooting, but also itself is used as diagnostic or treatment equipment. For example, for the detection and positioning of early and early malignant tissues, fluorescent endoscopes can be used in this examination, and the natural real color showing of the organization is not important. It is important that fluorescence is excited, and the pathological tissue...
