Description
Technical field
The present invention relates to a kind of vessel catheter device, especially relate to the vessel catheter device that a kind of percutaneous ultrasound guides.
Background technology
The precondition that conduit is a lot of medical diagnosis on disease and treatment is placed at Ink vessel transfusing, at present catheter in blood vessel being sent into the method for blood vessel in body is under the perspective of X-ray and the guiding of wire guide, vessel catheter is delivered to target location, the shortcoming of this method needs could implement in the Code in Hazardous Special Locations such as conduit room, the radiology department etc. that are provided with x-ray, which greatly limits the use (as bedside uses) of the method, and medical worker needs to wear heavier plumbous clothing, be exposed in X-radiation, the health of medical worker and patient all can be subject to the harm of radiation.Although there is a large amount of research in interventional radiology radiation protection, these researchs can not the radiation hazradial bundle problem of substantial solution X-ray.
The use first of intravascular ultrasound method (IVUS) was as far back as 1956, the blood vessel of Canis familiaris L. and the chambers of the heart are inserted with the conduit of ultrasonic probe in top by Cieszyski, successfully obtain the ultrasonoscopy of pulmonary artery and left and right ventricles, along with the development of science and technology, intravascular ultrasound inspection has developed into a video diagnostic technology very with practical value.
But when utilizing intravascular ultrasound method to carry out diagnostic detection or treatment operation to blood vessel, need to insert vessel catheter in advance, again ultrasonic probe is sent into target vascular site along vessel catheter, and inserting of traditional vessel catheter need under X-ray examination, guided by seal wire and insert vessel catheter, its operation has Code in Hazardous Special Locations requirement, and makes medical worker be subject to irradiation and the damage of x-ray.
Summary of the invention
The object of the invention is for above deficiency, a kind of percutaneous ultrasound is provided to guide vessel catheter device, this device makes medical personnel operate in the environment not having X-ray, can use by bedside, both the injury of X-ray had been avoided, operation place is unrestricted, and labor intensity and technical difficulty also alleviate greatly simultaneously.
In order to achieve the above object, percutaneous ultrasound disclosed by the invention guides vessel catheter device, comprises vessel catheter, miniature ultrasonic probe and signal transmission wire; Described miniature ultrasonic probe is arranged at the front end of described signal transmission wire, described miniature ultrasonic probe and the described signal transmission wire of part are arranged in described vessel catheter movably, and described miniature ultrasonic probe can be leant out or indentation by described vessel catheter front opening.
The signal that above-mentioned miniature ultrasonic probe detects is exported by signal transmission wire.
The front end of above-mentioned vessel catheter is blunt round, and the front end of above-mentioned miniature ultrasonic probe is blunt round.
The external diameter of above-mentioned vessel catheter is 1mm-50mm, and internal diameter is 0.5mm-40mm, and the length of described vessel catheter is 2.0m-3.0m, and the relevant parameter of concrete vessel catheter can regulate according to the actual thickness of blood vessel, length and the application that will carry out.
The cross section of above-mentioned vessel catheter and described signal transmission wire is concentric circular, the inwall of described vessel catheter and the outer wall of described signal transmission wire are not more than 0.5-3mm apart, this distance contributes to the external diameter reducing described vessel catheter, also contribute in vessel catheter, sending into other diagnosis or therapeutic device, as sacculus and support simultaneously.
Above-mentioned vessel catheter can make the body of vessel catheter have pliability, the out of shape of blood vessel can be adapted to, all engineering materials again with certain support force are simultaneously made, as polyethylene or other meet the engineering in medicine material of intensity and toughness reguirements, in use, the rear end of described vessel catheter is connected with Ultrasound Instrument.
Signal transmission wire in above-mentioned vessel catheter is connected with monitoring instrument, as for the ease of carrying out Real-Time Monitoring to the vascular pressure of patient, above-mentioned percutaneous ultrasound guides vessel catheter device to be also provided with pressure cvd sensor outward, and described pressure cvd sensor is connected to the external end of described vessel catheter.
The invention has the advantages that, the ultrasonic guidance vessel catheter device provided has the function of conduit and seal wire simultaneously, its conduit can hold ultrasonic signals propagate line by its inner chamber, its seal wire makes himself have and seeks footpath function, and there is certain support strength, during operation under the visual condition of ultrasonic probe, guide vessel catheter to follow blood vessel traveling together to advance, do not need completely to use the X-ray in traditional interventional therapy and wire guide, Ultrasound Instrument and vessel catheter is only used just can, can use in public ward, medical worker and patient is avoided to be subject to the infringement of X-ray, alleviate the labor intensity of medical personnel simultaneously, convenient operation and popularization.
