Abstract
A device for guiding a puncture needle used in CT (computerized tomography) comprises a guide section having an insertion hole for an introducer and the puncture needle, a pole brace having a leg and standing erect in parallel to the guide section, and a beam for connecting the guide section with the pole brace wherein the pole brace or the leg has a function for changing its length along the axial direction thereof, the beam for connecting both the guide section and the pole brace with each other is prepared from a moldable plastic material which allows X-rays to pass through the same in case of radiation into an integrally molded article. The guide section is provided with an openable holding section or a detachable holding section being in parallel to the insertion hole in order that the guiding device can be removed from the introducer and the puncture needle which have been inserted in the insertion hole 12, and further the guide section is provided with a metallic thin sheet which indicates a position of such metallic thin sheet in an image when radiation is made, thereby to-provide the device for guiding a puncture needle which has a simple structure and small number of parts, in which a space sufficient for performing manipulation of a puncturing operation with a needle can be assured, which is easily attached to a subject or a patient by an examiner or an operator, by which an exact puncturing operation can be made with respect to a target site, and further which can be removed from a subject's body surface with leaving the puncture needle as it is after having punctured a target site with the needle.
