Description
Technical field
The invention mainly relates to novel ultrasonic treatment to be popped one's head in, and more particularly to a kind of novel ultrasonic applied to clinical treatment is visited
Head.
Background technology
Medical ultrasound mainly has ultrasound detection and the aspect of application two of ultrasonic energy, commonly known as detection ultrasound and power
Ultrasound.Wherein detection ultrasound is the diagnosis that ultrasonic wave is applied to disease in the form of high frequency low energy, such as B ultrasound is imaged, ultrasound is more
General Le blood flow analysis, the detection of ultrasonic sclerotin and ultrasonic endoscopic etc..These technologies application in ultrasound intensity be all it is sufficiently small,
Irreversible biology change will not be typically produced in the tissue that ultrasound is passed through.Unlike detection ultrasound, treatment is super
Sound is that human body is acted in the form of low frequency high-energy to reach therapeutic purposes.Ultrasonic energy gathering by certain time in tissue
After collection, it can make tissue that certain change for being advantageous to disease treatment or making physical recovery health occur.
High intensity focused ultrasound (HIFU) treatment is even more in the recent studies on more paid close attention at present.Due to ultrasonic wave in itself
With higher focusing power and larger tissue penetration, ultrasonic energy can be focused on target tissue, and by target
The ability of all high strength supersonics of tissue resorption so that target tissue within the time of several seconds temperature rise to after certain temperature then
Necrosis.The technology can be used for prostate treatment of neurosurgery deep tumor, the treatment of lachrymal gland cancer and urological department etc..
But the treatment probe of presently used focusing ultrasound is all to need to smear substantial amounts of couplant on human body, with true
The effect for the treatment of can be reached from inside of human body is smoothly entered in vitro by protecting supersonic beam.But couplant has stronger stream
Dynamic property, it is impossible to therapentic part is maintained well, to reach more preferable therapeutic effect needs repeatedly substantial amounts of daubing coupling agent.
Furthermore because focused transducer all has certain curvature, it is impossible to be perfectly bonded with human body so that producing poor treatment
Effect.
The content of the invention
It is an object of the invention to provide a kind of novel ultrasonic probe applied to clinical treatment, to solve in above-mentioned background
The problem of proposition.
To achieve the above object, the present invention provides following technical scheme：
The present invention is using common spherical shell type potsherd as focused transducer, and in focused transducer front end, placement oil sac is as super
The medium layer of sound transmission, described oil sac are brought into close contact with focused transducer, and oil sac periphery is by the larger elastic membrane of one layer of elasticity
Composition, the inside of oil sac are filled with acoustic impedance with silicone oil similar in water to the medium as ultrasonic wave transmission.
Described oil sac is mainly the effect of couplants a large amount of and heavy before replacing, and supersonic beam is launched via transducer
After out, into oil sac, because oil sac periphery is wrapped up by the larger elastic film of elasticity, as long as in elastic film during use
The a small amount of couplant of upper smearing can just be bonded with human body perfection and be used for clinical treatment well.Oil sac and focused transducer is tight
It is closely connected to be combined, form the entirety of a ultrasonic probe.
Background technology is compared, the invention has the advantages that：
The present invention is popped one's head in by increasing the design of oil sac to improve the focused transducer needed for ultrasonic therapy.The invention cost it is low and
Compared with the method for a large amount of couplants of smearing that treatment at present uses, the dosage of couplant is more saved, is reduced due to couplant
The problem of couplant caused by mobility is big is lost in.In terms for the treatment of, the design of the design and elastic membrane that increase oil sac can make
Obtain ultrasonic probe preferably can fit with human body, reach more preferably therapeutic effect.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
In figure：1st, the backing of focused transducer, 2, spherical shell type focused transducer, 3, oil sac, 4, elastic membrane.
Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1：The present invention includes a spherical shell type focused transducer 2, and transducer rear end is lined with the suitable back of the body
Lining 1, transducer front end increase an oil sac 3 for being full of silicone oil, and oil sac is using elastic membrane parcel 4.The present embodiment is to integrate oil sac
In focused transducer front end, being integrally formed structure, it is designed to good be used as by increasing in transducer front end oil sac
The dielectric layer of ultrasonic propagation.Oil sac, to be bonded organism, reaches more preferable treatment using the stronger elastic membrane parcel of elasticity
Effect.
Described oil sac, it is mainly used in propagating the ultrasonic wave launched by focused transducer, as preferable dielectric layer.It is and oily
Intracapsular portion is flooded with acoustic impedance and the close silicone oil of water, is more beneficial for the propagation of ultrasonic wave wherein, big before even more instead of
The couplant of amount, it can really reach original effect or even more preferable.
Described elastic membrane, for the exterior material as oil sac to wrap up silicone oil, the elastic membrane needs preferable elasticity,
In order to be flexibly applied to treat each position of body.Only need to smear a small amount of couplant in elastic membrane during treatment, just can
Direct contact treatment body, reach the effect for the treatment of.
Below for the invention will be further described：
The preparation of novel ultrasonic probe
Step 1）The making of spherical shell type focused transducer.According to every ginseng such as different area for treatment environment and treatment depth
Number to the radius of curvature of transducer material, size and transducer, it is necessary to make a choice.And it is equipped with for focused transducer to close
Suitable back lining materials, to ensure that sound wave is preferably launched to orientation treatment.
Step 2）It is equipped with and the supporting oil sac of transducer.Considering the spherical shell type focused transducer of different size and parameter needs
Be equipped with the oil sac of different size, oil sac needs to be brought into close contact with focused transducer, and accomplish to fix all the time in transducer front end,
Medium layer as ultrasonic propagation.
Step 3）Select elastic membrane.Because the new new line needs to directly act on organism, but because organism has
A little positions are not very smooth, to accomplish that the degree of perfect fitting needs to wrap up the material of oil sac with preferable elasticity.
Therefore the design of elastic membrane is very important, and because the new detector acts on clinical trial, elastic membrane is even more to require
From the material to human body fanout free region.
The use of novel ultrasonic probe
Step 1）Smear a small amount of couplant.Although adding dielectric layer of the oil sac structure as transonic in probe distal end,
But a small amount of couplant need to also be smeared on human body by acting on human body, it is ensured that ultrasound smoothly can enter into the human body through oil sac
Portion reaches the effect for the treatment of.
Step 2）Treatment.According to different disease stoves, the parameter of focused transducer is adjusted, by the new detector according to step 3）
Operation measure be applied to focal area.The use for not only reducing couplant in the presence of novel ultrasonic probe also add
The comfort experience of patient.
