Summary of the invention
This utility model provides a kind of ultrasonic probe that has the focus indication in order to overcome the danger that there is the damage cornea in existing ultrasound biomicroscopy UBM probe, and this ultrasonic probe can be indicated the focal position of transducer accurately, can greatly reduce the risk of corneal injury.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of ultrasonic probe with the focus indication, comprise a ultrasonic transducer fan-shaped or linear mechanical scans, its characteristic point is: at least two visible light sources of configuration on the transducer enclosure, and be adjusted to disposing or become the light beam of light source of three configurations, it is pooled a bit, on the focal position when this point is positioned at ultrasonic transducer and is in quiescent condition.
On the focal position when light beam of visible light source pools and a little is positioned at ultrasonic transducer and is in quiescent condition.
Visible light source directly is fixed on the described ultrasonic transducer shell or passes through a rigid mount indirect securement on transducer enclosure.
Visible light source is connected with the control circuit of probe or the control circuit of independent design visible light source.
The light beam that visible light source sends forms the diameter of hot spot less than 3mm in distance light source 1-5mm place.
Visible light source immerses below the liquid level of couplant when normal the use.
The beneficial effects of the utility model are: this utility model is owing to indicating the focal position of transducer accurately, so can greatly reduce the risk of corneal injury.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is further described.
As shown in Figure 1, the ultrasonic probe of band focus indication of the present utility model, comprise fan-shaped or the ultrasonic transducer 14 of linear mechanical scanning and two or more visible light sources 9 (as light emitting diode) of configuration on transducer enclosure 4, probe cable 7, be adjusted to disposing or become the light beam of light source 3 of three configurations, make it pool 1: 11, on the focal position when this point 11 is positioned at ultrasonic transducer 14 and is in quiescent condition.If want indicate ultrasound transducer 14 to be in the focal position of quiescent condition, can with dispose in pairs or become the visible light source 9 of three configurations directly to be fixed on the ultrasonic transducer shell 4 or by rigid mount 6 indirect securement on transducer enclosure 4, need adjust light beam 3 during fixed light source 9, on the focal position the when light beam 3 that two light sources 9 are sent converges in ultrasonic transducer 14 and is in quiescent condition.Can design two kinds of light source 9 fixed structures as required, a kind of is the convergent point fixed-site that visible light source 9 is produced, and another kind is that the convergent point position that produced of visible light source 9 is adjustable.The situation of the convergent point fixed-site that is produced for visible light source 9, a visible light source 9 that disposes in pairs can be fixed on transducer enclosure 4 or the rigid mount 6 with 180 degree angle symmetries, when fixing this, adjust light beam 3, the focal position when making its point that pools be in ultrasonic transducer 14 quiescent conditions to light source 9; Also three visible light sources 9 can be fixed on transducer enclosure 4 or the rigid mount 6 with 120 degree angles, when fixing these three light sources 9, adjust light beam 3, the focal position when making its point that pools be in ultrasonic transducer 14 tranquillization situations.The adjustable situation in convergent point position that is produced for visible light source 9, a visible light source 9 can be fixed on transducer enclosure 4 or the rigid mount 6, its light beam 3 is parallel with acoustic beam, the light beam 3 that another light source 9 is sent is adjustable, it is adjustable that this moment, both converged the point and the distance between the transducer 14 that form, when changing ultrasonic transducer 14, the convergent point position is adjusted in the focal position in the time of can be according to the quiescent condition of employed acoustic transducer; Also two pairs or more visible light source 9 can be fixed on transducer enclosure 4 or the rigid mount 6, every pair of visible light source 9 is with 180 degree angle balanced configurations, every pair of light source 9 is determined a convergent point position, focal position when these convergent point positions can be in quiescent condition with the ultrasonic transducer 14 of frequent use overlaps, when changing transducer, can make corresponding 9 pairs of work of visible light source, the focal position when indicating it to be in quiescent condition.Adopt the ultrasonic probe of this kind band focus indication, can see the focal position when the indicated transducer 14 of point that two light beams 3 converge is in quiescent condition clearly, and then reduced the risk of cornea 12 damages greatly.
In Fig. 1, patient gets dorsal position, and eyeball 1 to be checked splashes into local anesthetic, sandwiches suitable eyecup 2 in the eyelid, and built-in normal saline is as couplant 10.The doctor holds probing shell 8, treat that transducer is invaded and promptly open instrument behind the saline and scan, careful on one side transducer 14 positions of adjusting, whether pool one 11 on one side if observing 9 pairs of light beams that send 3 of light source, converge fully until two hot spots, think focal position when finding ultrasonic transducer 14 to be in quiescent condition.
In Fig. 2, transducer enclosure can screw in the transducer enclosure jack 13 on the rigid mount 6, and visible light source can be fixed in the light source slot 5, and the light beam that sends becomes any acute angle with acoustic beam.
In Fig. 3, transducer enclosure can screw in the transducer enclosure jack 13 on the rigid mount 6, and visible light source 9 is fixed in the light source slot 5 with 180 degree angles, and the light beam that sends becomes any acute angle with acoustic beam.
In Fig. 4, the about 5mm of distance of focal position when ultrasonic transducer 14 is in quiescent condition and transducer 14, the about 10mm of the relative distance of two visible light sources 9 is so light beam 3 that this visible light source that disposes in pairs sends and acoustic beam are respectively in angle of 45 degrees.
In Fig. 5, visible light source 9 is fixed on the transducer enclosure 4 or on the rigid mount 6, its light beam 3 is parallel with acoustic beam, the light beam 3 that another light source 9 is sent is adjustable, it is adjustable that this moment, both converged the point 11 and the distance between the transducer 14 that form, when changing ultrasonic transducer 14, convergent point 11 positions are adjusted in the focal position in the time of can be according to the quiescent condition of employed acoustic transducer.
