摘要： A puncture needle capable of clear imaging even if an angle to the irradiation direction of a detection wave such as an ultrasonic wave of an ultrasonic probe is small. According to one embodiment, a ultrasonic puncture needle (1) that conducts puncturing while observing a puncturing condition by means of a ultrasonic image is formed with an edge (13) at the tip end of a puncture needle main body (1), and formed at a specified position of the puncture needle main body (11) with at least one corner cube mirror (12) formed by a triangular pyramid recess. Since a ultrasonic wave oscillated from the ultrasonic probe is reflected off the corner cube mirror (12) to be returned to the ultrasonic probe, the reflected wave progresses in the same direction as the incident direction of the ultrasonic wave to be positively returned to the probe even when an angle formed by the irradiation route of a ultrasonic wave and the axis of the puncture needle is small.

摘要： A set of double needles for injecting liquid medicine into a patient through a single injection point contains an inner curved needle slidably and rotatably supported within a shorter outer needle. The distal end of the inner needle can protrude from the outer needle to extend sideways, in a controlled direction and extent. The direction in which the inner needle point is inserted into the patient is determined by controllably rotating and engaging a base of the inner needle with respect to a base of the outer needle, with structure provided to prevent unintentional relative rotation of the needles. Liquid medicine may thus be infused into the body of a patient at a number of locations at a preselected depth into the body and within a zone laterally extending from the distal end of the outer needle. The inner needle, which may have a lateral hole at its end, is withdrawable within the outer needle and straightens within the latter during the course of such a withdrawal. A flexible adaptor is provided between the needles and a supply of liquid medicine.

摘要： A set of double needles of injecting liquid medicine comprises an inner needle and an outer needle into which the inner needle is inserted. The inner needle is longer than the outer needle and has a curved portion at the top thereof, so that the curved portion of the inner needle protrudes from the outer needle when the inner needle is fully inserted into the outer needle. On the other hand, the curved portion of the inner needle is straightened in the outer needle when the inner needle is retracted in the outer needle so that the inner needle can be rotated therein whereby the injecting point can be varied in a predetermined area in a single puncturing of the needles.

摘要： In application of a biopsy needle set which is utilized for collecting diseased tissue sections from internal organs in a human body without requiring surgical operation, it is desirable to be certainly taken out the tissue sections by single puncture and to decrease injury of such diseased part in addition, to reduce pain in the patient at the time of sticking into the human body with the needle. In an end of suction type biopsy needle set containing double needle set of an outer needle and an inner needle, the outer needle is narrowed to form a closely contacting portion with the inner needle, whereby negative pressure can be accumulated in a cylinder at the early stage of such suction, while thus accumulated negative pressure is transferred to an opening of the outer needle at the moment when the withdrawn inner needle is passed through the above described closely contacting portion, so that such suction force sufficient for collecting the tissue sections is produced. In this case, valve function of the needle tip construction in the above biopsy needle set can realize reliability of collecting the tissue sections. Furthermore suction can be in one-handed operation by such construction that a plunger is provided with a knob projecting through the notched split formed on the cylinder.
