The utility model discloses have following beneficial effect at least:

1) optical (imaging) positioning is used, the cost is low, and the precision is high.

The medical ultrasonic probe has high positioning requirement and small error, and the ultrasonic probe positioned by other methods usually needs to spend high cost and use a high-precision sensor, and even needs to make certain changes to the functional structure of the ultrasonic probe. By shooting the image of the body contact surface and comparing the moving distance, the error range can be reduced within 1cm

2) Omnibearing positioning without dead angle

Because in the use of ultrasonic probe in medical science, the supersound does not necessarily use in the health front, consequently under some specific uses, can appear monitoring dead angle, if survey the face to the health and scan the time, if the supersound scheme of external transducer that uses, if accomplish all-round no dead angle as needs, then need arrange a plurality of monitoring points, bring huge cost and technical difficulty this moment.

The imaging assembly is placed inside the ultrasonic probe, not only used for acquiring a contact surface image, but also used for ensuring the synchronism of the probe and imaging. The contact surface is higher in contact degree of coincidence between a human body and the detection surface of the probe, and better in synchronism under the action of force and couplant, so that position change errors caused by posture changes of the probe are not easy to generate compared with other positioning modes of the ultrasonic probe.

Detailed Description

The utility model discloses an ultrasonic probe that can fix a position, the embodiment of specific use as follows:

the detection surface of the ultrasonic probe has an opening for allowing the imaging assembly to image the body contacting surface through the opening. Generally, to avoid affecting the detectability of the ultrasound probe, referring to fig. 2, the opening lateral extension 200 does not have the ability to transmit and receive ultrasound, and typically, the opening lateral extension 200 is located in a cavity that is not within the range of the transducer (i.e., there is no ultrasound transmitter and receiver in the ultrasound radiation direction in the cavity). In some other embodiments, the longitudinally extending surface 201 of the opening may be rendered incapable of transmitting and receiving ultrasound, typically by using a plurality of transducers in parallel. Typically, the opening will be in the middle of the test face and in close proximity to the back or front of the probe.

Above the interior of the opening there is an imaging assembly 101, which typically will be a high speed camera, or other imaging device based on optical principles. To ensure that the imaging assembly has sufficient light to image, the probe contact surface may be wedge-shaped or a light emitting element, such as a led lamp, may be mounted in the imaging assembly. Preferably, the imaging assembly may be a thermal imaging device. The distance from the imaging assembly to the opening is typically the lowest imaging distance of the imaging assembly.

After the imaging component acquires the image of the body contact surface, the image is transmitted to the image processing module 102, the module can compare the characteristic points of the two images within a certain time, and the translation distance of the two images is calculated through an image algorithm, namely the translation distance of the probe. This translation distance is a displacement in the horizontal and vertical directions relative to the probe by way of the fixation of the imaging assembly and ultrasound housing.

In a specific use, before the use, a calibration link is often used for determining an initial point, and the translation distance of the probe calculated by the image processing module is matched with the initial point, so that the position coordinate of the current ultrasonic probe relative to the initial point can be determined.

Because the detection surface has the opening, in order to prevent the couplant from flowing backward into the opening when using the ultrasonic probe, a gasket 100 is fixed at the opening, and the gasket is a transparent gasket generally.

Because skin elasticity to and the effect of the time of probe use power adds the couplant, the health surface can closely laminate including the contact surface opening with the contact surface, under the anti crooked condition of transparent gasket for when the probe gesture changes, the health surface still keeps good contact with the probe contact surface, so when just fine stopping the probe gesture change, also can not produce position monitoring's deviation.

Under the better condition, the printing opacity gasket can be integrated into one piece with the detection face, only possess the luminousness in the open position, does not have the opening of practical meaning on the detection face this moment, and the position top is a cavity that can be used to fixed formation of image subassembly and obtain the contact surface image.

The above, only be the embodiments of some of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
