Technical field
The invention belongs to the ultrasonic therapy technical field, be specifically related to a kind of ultrasonic therapy head and contain the ultrasonic therapeutical system of this ultrasonic therapy head.
Background technology
Focused ultrasound therapy is that a kind of non-intervention type does not have the wound Therapeutic Method, especially be fit to tumor patient is treated, littler than traditional surgery or chemotherapy to patient's damage, thereby its application development is very fast, and indication comprises hepatocarcinoma, osteosarcoma, breast carcinoma, cancer of pancreas, renal carcinoma, soft tissue neoplasms etc.
Mostly the focused ultrasound therapy of prior art is to utilize fixed ultrasonic therapy head that different groups or individuality are treated under the location of B ultrasonic equipment and monitoring.Because the angle of incidence θ of this fixed treatment head is changeless, therefore can not adjust ultrasonic incident angle according to different patients, the sound intensity (being ultrasonic energy) in can not reduction sound channel range on the unit are, when the sound intensity on the unit are is excessive, easily damage is caused at other positions of human body.Fig. 1 is the structural representation of ultrasonic therapeutical system in the prior art.Among Fig. 1, ultrasonic therapy 1 is spherical concave surface, and the pairing angle of incidence θ of this concave surface is about 65 °, and its external diameter is generally the 100-150 millimeter, this treatment head can the ultrasonic waves transmitted energy can satisfy the needs of treatment in theory.But in the clinical practice of reality, bone to hyperacoustic anti-/ scattering reduced the treatment energy that arrives the target area; In addition, during the treatment deep tumor, other tissue has also caused arriving the reduction that institute's energy requirement is treated in the target area to hyperacoustic decay on the ultrasonic acoustic passage, influences therapeutic effect.
Should guarantee to arrive the needed gross energy in target area when using ultrasonic therapeutical system to treat, will guarantee also simultaneously that other is organized in the human body not suffer damage that this is the primary condition of carrying out ultrasonic therapy.When determining the required ultrasonic gross energy of treatment, must consider the target area to the tissue between the ultrasound emission source to ultransonic effect (as reflection, absorption, scattering etc.), also must consider by size, the locus of treatment tumor, determine the required energy range of its coagulation necrosis, simultaneously, the sound characteristics of other tissue on the ultrasonic acoustic passage, the maximum sound intensity of unit are that may bear also need be included in the treatment planning.Based on above factor, satisfy the treatment energy requirement, two kinds of ways of general at present employing: 1, increase hyperacoustic emitted energy; 2, removing bone is to reduce the decay of energy, excision rib during such as the treatment liver tumor.But the increase ultrasonic energy can make the probability of patient's bone, skin and the damage of sound channel organization strengthen; And removing bone can cause patient's lifelong disability with the way that reduces energy attenuation.

The body surface shape that the shape that solves another kind of technical scheme that the technology of the present invention problem adopted and be this described ultrasonic therapy head and human body contact position and human body are corresponding matches.
When the geometry of the shape of ultrasonic therapy head and patient's body surface touching position and patient's body surface matches, the long-pending big 1.5-2.5 of the existing ultrasonic therapy head surface of the surface area ratio of ultrasonic therapy head provided by the present invention doubly, therefore increased the surface area that ultrasound wave penetrates patient's skin surface, under the prerequisite that guarantees the required ultrasonic energy of treatment, also reduced the sound intensity that other tissue bears on the unit are sound passage, other tissue damaged's probability reduces on the feasible sound passage.
Preferably, the surface area of ultrasonic therapy head and human body contact position is the 30000-35000 square millimeter.
Described ultrasonic therapy head and human body contact position are sphere, and one angle of incidence θ span can be 90 °-110 °, and another angle of incidence α span can be 50 °-65 °.
A kind of ultrasonic therapeutical system that contains above-mentioned ultrasonic therapy head.
Preferably, there is supervising device at the center of ultrasonic therapy head, and monitoring arrangement adopts Ultrasonic-B probe.
Owing to focus is usually located at patient's rib near zone, and the skin surface shape of different patient at this place differs, therefore the ultrasonic therapy head that can select to have different curvature to different patients.Thereby select suitable ultrasound wave angle of incidence, effectively the sound intensity on the unit are in the reduction sound channel range has reduced the impaired probability of other organs in the human body.
Therefore, ultrasonic therapy head of the present invention has also reduced the sound intensity that other tissue bears on the unit are sound passage under the prerequisite that guarantees the required ultrasonic energy of treatment, and other tissue damaged's probability reduces on the feasible sound passage.
