The invention relates to the technical field of medical apparatuses. The invention discloses a built-in medical ultrasonic thrombolytic therapy apparatus, which comprises an infusion device, an ultrasonic loading module and an ultrasonic indwelling wave-
guide tube. A
front cover plate and an amplitude-change pole of an ultrasonic
transducer in the ultrasonic loading module are made from a TC4
titanium alloy material, and through holes, which are [phi]1mm in
diameter, are kept in the middles of the
front cover plate and the amplitude-change pole. The ultrasonic indwelling wave-
guide tube entersinto a
blood vessel from the upstream side of the
blood vessel that
thrombus occurs along the direction of a
blood flow. A plurality of small holes are excavated in two sides of the part, which enters the
blood vessel, of the ultrasonic indwelling wave-
guide tube, so that ultrasonic wave is directly emitted into the blood vessel having the
thrombus, and then under the assistance of
thrombolytic agent, the
thrombus can be ablated. Based upon experimental
verification, the therapy apparatus, on treating thrombotic diseases, is non-invasive, simple and convenient to operate and suitable for reuse. Ultrasonic energy merely plays a local role
in vivo, and an ultrasonic action and medicines directly reach focuses, so that a good
thrombolysis effect is achieved; and meanwhile, the therapy apparatus has the huge advantages of being low in injury on surrounding tissues, safe and free from side effects and adverse reactions, and the like.
