Abstract

A probe is composed of a central ultrasonic Doppler effect transducer surrounded by several identical ultrasonic transducers which can be manipulated to create a focal point. The transducers are embedded in a pliable plastic which may be moulded into shape by hand pressure. A network of metal strips are embedded in grooves in the plastic. Each is soldered to one of the fixed ultrasonic transducers arranged in a ring with the others. Each transmits via its conductor a similar field but varied in orientation. The operating band is 2 to 9 MHz. A computer is used to vary the frequency so as to focus on a particular cell and produce the signals in phase at the focal point. ADVANTAGE - Enables abnormalities to be acted on as soon as they are discovered.

Description

La présente invention concerne une sonde à ultrason multifonctionnelle permettant simultanément l'échographie avec effet doppler et une action mécanique à volonté sur des cellules anormales. The present invention relates to a multifunctional ultrasound probe simultaneously allowing ultrasound with doppler effect and mechanical action at will on abnormal cells.

L'utilisation traditionnelle de l'échographie permet de visualiser et de mesurer certaines parties internes-du corps et de constater des anomalies éventuelles sans action directe sur certaines parties anormales. The traditional use of ultrasound makes it possible to visualize and measure certain internal parts of the body and to note any anomalies without direct action on certain abnormal parts.

Cette sonde (Fig. 1) assistée de l'ordinateur permet de remédier à cet inconvénient. Elle comporte autour du transducteur ultrasonique à effet doppler (6) plusieurs transducteurs (7) (Fig. 3) de caractéristiques rigoureusement identiques. Ces transducteurs (7) sont de moyenne puissance classique et possédent une plage de vibration ultrasonique de 2 à 9 M Hz. This computer-assisted probe (Fig. 1) overcomes this drawback. It comprises around the ultrasonic Doppler transducer (6) several transducers (7) (Fig. 3) with strictly identical characteristics. These transducers (7) are of conventional medium power and have an ultrasonic vibration range of 2 to 9 M Hz.

L'ensemble scellé dans une matière plastique est déformable (1) et (8) par la pression de la main qui tient la poignée. Un réseau métallique (5) en forme de rainures scellées dans la- matière plastique (1) et soudées à un cerceau métallique (2) contre lequel sont fixés les transducteurs ultrasoniques (7) transmet une variation d'orientation presque identique aux transducteurs. The assembly sealed in a plastic material is deformable (1) and (8) by the pressure of the hand holding the handle. A metallic network (5) in the form of grooves sealed in the plastic material (1) and welded to a metallic hoop (2) against which the ultrasonic transducers (7) are fixed transmits a variation in orientation almost identical to the transducers.

Cette variation d'orientation a pour effet de changer le point focal des impulsions simultanées (Fig.4) à volonté d'environ 10 à 30 cm. This variation in orientation has the effect of changing the focal point of the simultaneous pulses (Fig. 4) at will by about 10 to 30 cm.

L'ordinateur réglera la fréquence optimale de pénétration et la visualisation.The computer will adjust the optimal frequency of penetration and viewing.

La fréquence de chaque transducteur sera transmise sans géner les cellules traversées. Par contre au point focal, les fréquences identiques en phase réglées pae ordinateur créeront des vibrations d'une grande amplitude : une ribration moléculaire explosive ou cavitation microscopique due à l'onde de choc constitué de faibles amplitudes superposées, (Fig.4), sur les cellules anormales disloquant les calthrates (FiG.6), chélates (Fig.5), cryptates (Fig.7) et électures (Fig.6). Ce sont des molécules d'eau, des molécules pol#non-saturées et des acides nucléiques polymérisées en forme de cage piégeant les ions et les molècules de gaz sous plusieurs milliers d'atmosphères. Cette polymérisation étant due à une excitation fréquencielle éléc- tromagnétique des chélates provoquant un effet laser-(Fig.5) a et b- des ions et molécules piégées ; semblable à l'action des U.V. sur certains po l##res en condition anaérobie dans la fabrication de colles.The frequency of each transducer will be transmitted without disturbing the cells crossed. On the other hand at the focal point, the identical frequencies in phase regulated by the computer will create vibrations of a large amplitude: an explosive molecular ribration or microscopic cavitation due to the shock wave made up of small superimposed amplitudes, (Fig. 4), on abnormal cells dislocating calthrates (FiG.6), chelates (Fig.5), cryptates (Fig.7) and electures (Fig.6). These are water molecules, unsaturated pol # molecules, and cage-shaped polymeric nucleic acids trapping ions and gas molecules under several thousand atmospheres. This polymerization being due to an electromagnetic frequency excitation of the chelates causing a laser effect (Fig. 5) a and b- of trapped ions and molecules; similar to the action of UV on certain poles in anaerobic conditions in the manufacture of adhesives.

La sonde à transducteurs multiples et à transmission simultanée d'ultrason a une action d'agitation mécanique sur le milieu à tendance cancéreuse brisant les interphases et les polarisations orientées (Fig.8) rétablissant la distribution gauzienne des particules biotique dans le plasma extra et intracellulaire. The probe with multiple transducers and simultaneous transmission of ultrasound has a mechanical agitation action on the cancer-prone medium breaking the interphases and oriented polarizations (Fig. 8) restoring the gauzian distribution of biotic particles in extra and intracellular plasma. .
