Abstract
The utility model provides a lens, its characterized in that: of applying to on the 4D probe adopt the plastic lens of plano -concave structure, replace conventional plano -convex structure rubber lens. Fine solution the sound head part of 4D probe because operational environment's difference and the acoustic attenuation increase and the focus ability that cause weaken. Replace rubber materials through epoxy, not only more accord with the impedance match nature of supersound sound transmission requirement, strengthened the protection to the sound head simultaneously.
Description
Technical field
The present invention relates to field of medical technology, be specifically related to the acoustic lens that a kind of 4D pops one's head in.
Background technology
4D color ultrasound belongs to the one of color ultrasound, is exactly the color doppler ultrasonography of three-dimensional Dynamic Announce in fact.4D color ultrasound common at present mainly with the sound head that step motor drive probe is inner, makes its sector scanning thus obtains a series of tangent plane picture, and then by the computing of ultrasonic main frame, can the 3 d image of Dynamic Announce by these data recombination one-tenth.
Because sound head needs sector scanning, so need to add one deck entrant sound protective cover between sound head and tissue, and in order to ensure that ultrasonic signal transmits smoothly, sound head can not be hindered again to move simultaneously, usually filling with entrant sound liquid in the middle of sound head and protective cover.
Add entrant sound liquid and protective cover double-layer structure between sound head and human body, the acoustic impedance matched environment of original lens and human body also there occurs change, causes conventional rubber lens focus ultrasonic hydraulic performance decline, and the acoustic energy loss of transmittance process is also larger.
Summary of the invention
The technical problem to be solved in the present invention is: the sound head part of 4D probe is owing to being immersed in oil environment, and acoustical match there occurs change, and acoustic lens also needs corresponding adjustment naturally.Meanwhile, because sound head need not directly and direct body contact, so can adopt the plastic lens of plano-concave structure, so both decrease the acoustic attenuation that lens bring, the focusing performance of sound head is also better.
The present invention for solving the problems of the technologies described above adopted technical scheme is: the rubber lens of the plano-convex structure discarded tradition, and adopts the plastic lens of plano-concave structure.And in plastics kingdom, contrast the acoustic attenuation coefficient of each kind, operational characteristic, material source and price etc., what truly have practical value only has polystyrene, ABS plastic, lucite and epoxy resin etc. limited several.And the outstanding advantages of epoxy resin is can cast molding, and inherently high-quality binding agent, therefore the present invention selects epoxy resin as lens material.

Comprise with lower component: 1. acoustic lens; 2. matching layer; 3. wafer; 4. sound absorption block.
The sound head longitdinal cross-section diagram that Figure 24 D pops one's head in.
Comprise with lower component: 1. acoustic lens; 2. matching layer; 3. wafer; 4. sound absorption block.
Detailed description of the invention
According to drawings and embodiments the present invention is described in further detail below:
As Fig. 1, be the sound head part of 4D probe, the plano-convex structure rubber lens of current ultrasound field main flow are mainly replaced with the plano-concave structural epoxy resins lens in diagram by this patent.Specific implementation method is the sound head posting matching layer is placed in lens die and fixes structure, then epoxy resin deployed by a certain percentage is in advance injected mould, takes out sound head and namely complete after resin solidification.
Those skilled in the art do not depart from essence of the present invention and spirit, various deformation scheme can be had to realize the present invention, the foregoing is only the better feasible embodiment of the present invention, not thereby interest field of the present invention is limited to, the equivalent structure change that all utilizations description of the present invention and accompanying drawing content are done, is all contained within interest field of the present invention.
Claims (2)
