Abstract
The invention provides an ultrasonic 2D phased array probe for a laparoscopic surgery and a method for manufacturing same. The ultrasonic 2D phased array probe employs a wiring method in which a flexible circuit board conducts full connection from a backing part, thus providing guarantee for the miniaturization of multi-phased ultrasonic devices and meeting the requirements of the laparoscopic surgery.
Description
Technical field
The invention belongs to medical ultrasound imaging apparatus field, be specifically related to a kind of ultrasonic battle array probe for laparoscopic surgery and preparation method thereof.
Background technology
Due to have wound little, recover the feature such as fast, laparoscopic surgery just progressively replaces traditional open surgery.But laparoscopic surgery still Shortcomings part at present: because present peritoneoscope is optical imagery, the surface texture of internal organs and tissue can only be observed, organization internal information cannot be detected, so laparoscopic surgery can not measure pathological changes excision extension in real time, focus may be caused remaining, in addition, easily cause blood vessel injury during operation, severe haemorrhage causes operative failure usually.
Three-dimensional ultrasound can provide real-time three-dimensional medical image, and can present the internal structural information of tissue.Effectively can make up existing laparoscopic technique with three-dimensional ultrasound as surgical navigational not enough, safety and the effectiveness of laparoscopic surgery can be improved further.
The core of three-D ultrasonic operation guiding system is ultrasonic battle array probe, but special ultrasonic the battle array being applicable to laparoscopic surgery is popped one's head in, and there is not been reported.
Summary of the invention
The invention provides a kind of ultrasonic battle array probe for laparoscopic surgery and preparation method thereof.Laparoscopic surgery sets up operation path by the skin incision of about 2-5cm, uses operating parts to complete operation through passage.So have strict requirement for the size of ultrasonic probe, usual probe diameter should be less than 1cm.The restriction of size increases the development difficulty, particularly wiring of probe and the difficulty of encapsulation, therefore needs particular design.
Compared with the patent (such as patent 200810020605.1,201120010024.7,200810122207.0,200980130213.3,200820167276.9,200820047203.6) of current existing regarding three-dimensional ultrasound imaging probe, the present invention specially for the specific demand of laparoscopic surgery, for solid foundation has been established in the application of three-D ultrasonic airmanship in laparoscopic surgery.
The method of production of two-dimentional 8 × 8 ultrasonic corrugated battle array probes of the present invention is see accompanying drawing 2.
Accompanying drawing explanation
Fig. 1 is the full structural representation connected of 8 × 8 ultrasonic corrugated battle array probe prepared by the present invention.
Fig. 2 is the flow chart of the method for production of two dimension 8 × 8 ultrasonic corrugated battle array probe prepared by the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in detail.
First pour on piezoelectric patches backing (here be conduction backing), backing is contacted completely with piezoelectric patches.After backing solidifies, mechanically the piezoelectric patches of perfusion backing is cut, first at horizontal direction, sample is cut, cut and wear piezoelectric patches and certain thickness backing, but do not cut and wear backing, then insert decoupling material, as e-poxy; After solidifying Deng decoupling material, at longitudinal direction, sample is cut, cut the backing wearing piezoelectric patches and previous step same thickness, but do not cut and wear backing, then insert decoupling material, as e-poxy.After decoupling material solidifies, thinning backing is to the array just exposed after cutting.Finally flexible circuit board compression moulding is attached in the plane of backing.
Fig. 1 display be the structural representation of battle array probe in two dimension 8 × 8 ultrasonic corrugated prepared by the present invention, the basic element of character comprises: (material of piezoelectricity array element can be piezoelectric ceramics to 8 × 8 the piezoelectricity array elements 101 equidistantly arranged by designed interval, piezoelectric monocrystal, piezopolymer or piezo-electricity composite material, the present invention does not limit), the matching layer 102 being positioned at piezoelectricity array element upper end (selects the matching layer of conduction, the thickness of matching layer and parameters,acoustic are according to the operating frequency of piezoelectricity array element and electricity, parameters,acoustic designs), the back lining materials 103 being positioned at piezoelectricity array element lower end (selects the back lining materials of conduction, in order to absorb the ultrasound wave of piezoelectricity array element backward launched, improve the imaging resolution of probe), be decoupling material 104 (in order to reduce the string wave action between piezoelectricity array element) in gap between each piezoelectricity array element, connect the internal wiring port one 05 (Wiring port can be integrated on flexible circuit board) of each array element counter electrode unit, each Wiring port connects the connecting line 106 (in order to transmit driving voltage signal and to receive echo voltage signal) of external connection port, the external connection port 107 connecting external circuit (selects manual wiring according to specific design array element size, photoetching, the technology such as wire-bonding).
It should be noted last that, above embodiment is only in order to illustrate the technology implementation scheme of this material but not to limit, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
