Title:
OPTICALLY IRRADIATING THERAPEUTIC INSTRUMENT
Document Type and Number:
Japanese Patent JPH06125998
Kind Code:
A
Abstract:
PURPOSE: To increase a treatment effect at a large lesion part by providing a device with a radiation source to produce a thermal amount of a specified range and a radiation guide to reflect most radiation in the device which utilizes a thermal effect produced by irradiation to a body surface or an inner cavity. CONSTITUTION: This treatment device has a mirror 4, an iodine tungsten lamp 2 and an infrared conductive quartz glass bar 1 arranged in a housing 6. The housing 6 is formed of a cylindrical aluminum barrel having a cooling passage 5 on a back of the mirror 4. The mirror 4 has a concave surface, which is plated with a copper layer. An iodine tungsten lamp 2 is arranged as a radiation source to produce a temperature up to 1900-2100K near a front focus point of the concave surface. Furthermore, an infrared conductive quartz glass bar 1 is arranged in the front of the lamp 2, wherein a tip of the bar extends at the outside of the housing 6. A cell tissue having a lesion part is necrotized by radiation irradiation from such treatment device.
