Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2005-233308, filed on Aug. 11 2005, the entire contents of which are incorporated herein by reference.
  • BACKGROUND OF THE INVENTION
  • An ultrasonic diagnostic apparatus is often used for puncture. In this case, an operator watches a monitor display of an ultrasound image of a live body and a puncture needle, and insertion of the puncture needle. In the puncture operation, a puncture adapter is often used, and a puncture guide marker is displayed on the monitor to serve as a direction guide to assist an operator during needle insertion. In one puncture method, a puncture adaptor is fixed at a predetermined position of an ultrasonic probe body. In this method, an operator must read an angle value by watching a scale on the adaptor, and set the angle value for displaying the angle of the puncture marker of the ultrasonic diagnostic apparatus. This setting enables display of the puncture guide image with an ultrasonic image on the display monitor. In this technique, which entails operator's reading and setting, an operator perform angle reading and setting every time the operator changes an angle of the puncture needle. This is complicated for the operator.
  • In another method, the above mentioned angle of the puncture needle guide is detected by a sensor set by the puncture guide, and the detected angle is delivered to a processing unit in an ultrasonic diagnostic apparatus. (For example, see JP2004-305535A.) The sensor detecting the angle of the puncture needle guide is provided near a part moving in accordance with the changing angle of the puncture needle, (for example, see FIG. 6 or FIG. 7 in JP2004-305535A) and the sensor detects the angle indirectly or directly. In this method, the puncture marker image displayed on the monitor is automatically changed in accordance with the detected angle.
  • However the puncture adaptor is often removably constructed so that operator can mount and remove it from a standard ultrasonic probe. In this case, provision must be made for delivering detected signal to the apparatus body. For example, in the case that probe cables double as the connection to apparatus body, a connection structure such as a connecter connecting to the ultrasonic probe and a cable leaded from the puncture adaptor is necessary. On the other hand, in the case that another cable is connected to the apparatus body, the increasing number of cables adversely impact operability, and providing a new connecter for puncture is needed.
  • Because a guiding portion of the puncture adaptor guides a needle inserted into a body, body fluid and body tissues adhere to the guides. In this situation, the guiding portion must be easily disinfected and sterilized or must be disposable. However, in the above mentioned case, use of the sensor makes the structure complicated, makes disinfection or sterilization of the guide difficult, and makes the guide too expensive to be disposable.
  • BRIEF SUMMARY OF THE INVENTION

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, various embodiments of the present invention are next described.
  • (First Exemplary Embodiment)
  • An ultrasonic probe 10 shown in FIG. 1 (b) includes a probe body 11 holding an ultrasonic transmit and receiving unit 12 having arrayed ultrasonic transducers, and an alternating photo sensor 13 including luminous elements 13 a and light sensitive elements 13 b. Lead wires of the luminous elements 13 a and the light sensitive elements 13 b are wired in a probe body 11. The wires are connected to a body of the ultrasonic diagnostic apparatus through a probe cable 11 c with read wires of ultrasonic transducers.
  • As a slide opening part 22 of puncture adaptor 20 shown in FIG. 1 (a) is positioned opposite the photo sensor 13 of the probe body 11, a holder 21 of the puncture adaptor 20 holds the probe body 11, as shown in FIG. 1(c). A slider 23, having a reflective face facing the probe body 11, is fitted into a slide opening part 22 of the puncture adaptor 20, and a needle guide 24 is fastened at one end of the slider 23 by screws (not shown) to the slider 23 and an adaptor part 25. A puncture needle 29 can be inserted into a puncture needle hole of the needle guide 24 as shown in FIG. 1 (c).
  • Next, the ultrasonic diagnostic apparatus to which the puncture adaptor 20 attaches, in this exemplary embodiment, is explained with reference to the schematic block diagram of FIG. 2.
  • As shown in the FIG. 2, the ultrasonic diagnostic apparatus includes a body 30 connected to an ultrasonic probe 10 with an puncture adaptor 20, an angle sensor signal from the ultrasonic probe 20 is inputted into the body 30, for processing within the body 30. Also connected to the body 30 is an input unit 41 for user interface with the body 30. The input unit 41 can be a key board, a track ball and/or an operation panel. A monitor 39 for displaying an image signal delivered from the body 30 is also connected to the body 30.
  • The body 30 includes an ultrasonic transmitting unit 31, an ultrasonic receiving unit 32, an image processing unit 33, a sensor IF (interface) unit 34, a database 35, a CPU unit 36 and a display unit 37. The ultrasonic transmitting unit 31 generates and applies a driving signal to the ultrasonic probe 10. The ultrasonic receiving unit 32 receives a received signal from the probe 10. The image processing unit 33 processes this received signal into an image signal. The sensor IF (interface) unit 34 receives a sensor signal from the ultrasonic probe 10 and converts this signal into an angle signal. The database 35 memorizes and saves a variety of data. The CPU unit 36 controls each of the components of the apparatus on the basis of an operation signal from the input unit 41. The display unit 37 converts a signal from the image processing unit 33 into a display format. An additional image signal like a signal based on a signal from sensor IF 34 is also processed into a graphical signal by this image processing unit 33. The display unit 37 delivers these signals to the monitor 39.
  • Next, the function and operation of the exemplary embodiment are explained in reference to FIG. 1.
  • At first, the holder 21 is fixed to the probe body 11 shown in FIG. 1 (b), so that the needle guide 24 of the puncture adaptor 20 lies near the end of the adaptor part 25. Then, as illustrated in FIG. 1(c), all of the luminance elements 13 a and the sensitive elements 13 b composing the photo sensor 13 are exposed. In this case, each sensitive element 13 b which does not receive light emitted from luminance elements 13 a likewise does not generate a signal. This position of the needle guide 24 corresponds to a maximum angle of insertion angles (in relation to a vertical insertion angle which is 0 degree) of the puncture needle.
  • Next, when an operator displaces the needle guide 24 and the slider 23 to the side of the probe body along the slide opening part 22 and reduces the insertion angle of the puncture needle, the slider 23 having a reflective surface on the side facing probe body 11 faces opposite some of the luminance elements 13 a and sensitive elements 13 b. At that time, light reflected off the reflecting surface impinges on the sensitive elements 13 b, and a detection signal is outputted from such sensitive elements 13 b. Such detection signals are delivered by a lead wires (not shown in the figures) provided in the probe body 11. These read wires are assembled in the probe cable 11 c with read wires for the ultrasonic transducer unit 12 provided at the top of ultrasonic probe 10, and these read wires are connected to the sensor IF unit 34. When the detective signal is inputted to the sensor IF unit 34, the unit measures an angle of the needle guide 24 by detecting how many sensitive elements 13 b detect the light from luminance elements 13 a. The result of angle detection is delivered to the CPU unit 36.
  • The CPU unit 36 directs the image storing device 38 to output data of the puncture guide image corresponding to the detected puncture needle insertion angle to the display unit 37. An operator can see the puncture guide image corresponding to a real needle angle on the monitor 39.
  • In addition, luminous elements 13 a and light sensitive elements 13 b of the alternating photo sensor 13 are arranged in pairs in the direction of a circular arc in the above explanation. However, pairs of the luminous elements 13 a and light sensitive elements 13 b may be arranged radially opposite each other with the pairs of luminous element 13 a and light sensitive element 13 b extending in a circular arc direction. This arrangement enables a high density of sensors and high accuracy of angle detection. In another implementation, the reflecting part of slider 23 may be composed of a plurality of reflecting parts having narrow reed shape, which also enables high accuracy of angle detection.
  • In the above explanation of the described exemplary embodiment, an ultrasonic diagnostic apparatus reads an angle of the needle guide, and automatically display an insertion position or angle of the puncture needle in an ultrasonic image. This enables provision of an ultrasonic diagnostic apparatus, an ultrasonic probe and a puncture adaptor which avoids a bothersome operation for display of a puncture guide image. In addition, because an angle detection sensor is arranged in the body of the ultrasonic probe, the puncture adaptor has no electrical machinery. Therefore this puncture adaptor can be disinfected and sterilized without concern for breakage or electric leakage caused by body fluids or heat. In addition, because the fabrication cost of the puncture adaptor can be lower than one having sensor, it is possible to treat the adaptor as disposable. Furthermore because read wires for sensor signals are provided in the probe body, it is not necessary that a connecting device be provided outside the probe. Because a cable for the sensor to the diagnostic apparatus body is united with a probe cable for transducers, there is no operability complication caused by an increasing number of cables when the puncture adaptor is used.
  • Furthermore, in the above explanation of this exemplary embodiment, because it is not necessary that electromagnetic devices be provided on the puncture adaptor, the cost for fabricating the puncture adaptor is lower than the cost for gabricating a puncture adaptor having magnetic elements described in the below mentioned third exemplary embodiment or fourth exemplary embodiment.
  • (Second Exemplary Embodiment)
  • In a second embodiment, as shown by FIG. 3, it is characteristic that a pattern having different degrees of reflection, for example a black and white stripe pattern, is provided on a probe body side of the slider 26. The pattern is detected by one pair of a luminance element 15 a and a sensitive element 15 b provided on the probe body 11. In the explanation of this exemplary embodiment, explanations of similarities with the first exemplary embodiment will be skipped, and differences will be mainly explained.
  • In this second exemplary embodiment, the needle guide 24 of the puncture adaptor 20 held by the probe body 11 a of the ultrasonic probe 10 a is moved to a desirable position. By this movement, when the stripe pattern on the slider 26 passes by the luminance element 15 a and the sensitive element 15 b, the sensitive element 15 b receives reflected light from the luminance element intermittently. A read wire for light receiving signals is provided in the probe body 11 a and the probe cable, and the signal is delivered to the sensor IF unit 34. This pulse train signal by intermittently receiving light is transformed to angle data by pulse counting of the sensor IF unit 34. The CPU unit 36 directs the image storing device 38 to output data of the puncture guide image corresponding to the detected puncture needle insert angle to the display unit 37. An operator can see the puncture guide image corresponding to an actual needle angle on the monitor 39.
  • In addition, in order to detect a direction of movement of the puncture needle, the photo sensor 15 may be composed as two sensitive elements and one luminance element between the two sensitive elements. In this case, by detecting each phase of light that enters into two sensitive elements, a direction of movement is distinguished.
  • Furthermore, the pattern on the slider 26 may be composed as an other monochrome pattern code which indicates puncture angles, for an example bar-code or a QR code (registered trade mark). In this case, the photo sensor 15 reads the code pattern, and the sensor IF unit 34 decodes this code.
  • In the above explanation of this exemplary embodiment, an ultrasonic diagnostic apparatus reads an angle of the needle guide and displays an insert position or angle of the puncture needle in an ultrasonic image automatically. This enables provision of an ultrasonic diagnostic apparatus, an ultrasonic probe and a puncture adaptor which avoids a bothersome operation for display of a puncture guide image. In addition, because the angle detection sensor is arranged in the body of ultrasonic probe, the puncture adaptor has no electrical machinery. Therefore this puncture adaptor can be disinfected and sterilized without concern for breakage or electric leakage caused by body fluids and heat. In addition, because the fabrication cost of the puncture adaptor can be lower than one having sensor, it is possible to treat the adaptor as disposable. Furthermore because the read wires for sensor signals are provided in the probe body, it is not necessary that connecting devices be provided outside the probe. Because cables for the sensors to the diagnostic apparatus body are united with the probe cable for the transducers, there is no operability complication caused by an increasing number of cables when the puncture adaptor is used.
  • Furthermore, in the above explanation of this second exemplary embodiment, because it is not necessary that electromagnetic devices be provided on the puncture adaptor, the cost for fabricating the puncture adaptor is lower than the cost for fabricating a puncture adaptor having magnetic elements described in the below mentioned third exemplary embodiment or fourth exemplary embodiment.
  • In addition, in the above explanation of this second exemplary embodiment, because the number of necessary sensors is two or three, the cost of fabrication of read wires and connecting devices for the sensor can be lower than the case of using more sensors.
  • (Third Exemplary Embodiment)
  • In a third exemplary embodiment as shown by FIG. 4, a magnetized magnetic element 27 a is provided on the probe body side of the slider 27 and a magnetic sensor unit formed by magneto metric sensors 16 a-16 f is provided at the probe body 11 b in a circular direction. In the explanation of this exemplary embodiment, explanation of similarities with the first exemplary embodiment will be skipped, and differences will be mainly explained.
  • In this exemplary embodiment, the needle guide 24 of the puncture adaptor 20 held by the probe body 11 b of the ultrasonic probe 10 b is moved to a desirable position. By this movement, when the magnetic element 27 a on the slider 27 passes past the magneto metric sensors 16 a-16 f, the magnetic metric sensors 16 a-16 f detect the passing of the magnetic element 27 a in turn. A read wire for detecting signals is provided in the probe body 11 a and the probe cable, and the signal is delivered to the sensor IF unit 34. When detected signals are inputted to the sensor IF unit 34, the unit 34 measures an angle of the needle guide 24 by detecting how many magneto metric sensors detect the passing. The CPU unit 36 directs the image storing device 38 to output data of the puncture guide image corresponding to the detected puncture needle insertion angle to the display unit 37. An operator can see the puncture guide image corresponding to a real needle angle on the monitor 39.
  • In the above explanation of this exemplary embodiment, an ultrasonic diagnostic apparatus reads an angle of the needle guide, and displays an insertion position or angle of the puncture needle in an ultrasonic image automatically. This enables provision of an ultrasonic diagnostic apparatus, an ultrasonic probe and a puncture adaptor which avoids a bothersome operation for display of a puncture guide image. In addition, because an angle detection sensor is arranged in the body of the ultrasonic probe, the puncture adaptor has no electrical machinery. Therefore this puncture adaptor can be disinfected and sterilized without concern for breakage or electric leakage caused by body fluid or heat. In addition, because the fabrication cost for the puncture adaptor can be lower than one having sensor, it is possible to treat the adaptor as disposable. Furthermore because read wires for sensor signals are provided in the probe body, it is not necessary that a connecting device be provided outside the probe. Because a cable for the sensor to the diagnostic apparatus body is united with a probe cable for transducers, there is no operability complication caused by an increasing number of cables when the puncture adaptor is used.
  • Furthermore, in the above explanation of this exemplary embodiment, because of noncontact sensing between the magneto metric sensors and the magnetic element, the magneto metric sensors 16 a-16 f can be provided inside the case of the probe body 11 b. In this case, a surface of the probe body 11 b can be formed without irregularities. So a probe washing operation is easy. Because of noncontact sensing, in a case that fluid and tissues of object adhere on the surface of probe body, there is no adverse effect on sensing.
  • Furthermore, in the above explanation of this exemplary embodiment, it is not necessary that a plurality of magnetic elements be provided on the slider. So the cost for composing puncture adaptor can be lower than the case of below mentioned fourth exemplary embodiment.
  • (Fourth Exemplary Embodiment)
  • In a fourth exemplary embodiment, as shown by FIG. 5, plural magnetized magnetic elements 28 a are provided on the probe body side of the slider 28 in a circular arc direction. The magnetized magnetic elements 28 a are detected by a magneto metric sensor 17 a provided on the probe body 11 c. In the explanation of this exemplary embodiment, explanation of similarities with the first exemplary embodiment will be skipped, and differences will be mainly explained.
  • In this exemplary embodiment, the needle guide 24 of the puncture adaptor 20 held by the probe body 11 a of the ultrasonic probe 10 a is moved to a desirable position. By this movement, when the magnetized magnetic elements 28 a on the slider 28 pass adjacent the magneto metric element 17 a, the magneto metric element 17 a detects passing of the magnetic elements 28 a in turn. A read wire for detecting signals is provided in the probe body 11 a and the probe cable, and the signal is delivered to the sensor IF unit 34. This pulse train signal produced by intermittent detecting of element 17 a is transformed to angle data by pulse counting of the sensor IF unit 34. The CPU unit 36 directs the image storing device 38 to output data of the puncture guide image corresponding to the detected puncture needle insertion angle to the display unit 37. An operator can see the puncture guide image corresponding to a real needle angle on the monitor 39.
  • In the above explanation of this exemplary embodiment, an ultrasonic diagnostic apparatus reads an angle of the needle guide, and automatically displays an insertion position or angle of the puncture needle in an ultrasonic image. This enables provision of an ultrasonic diagnostic apparatus, an ultrasonic probe and a puncture adaptor which avoids a bothersome operation for display of a puncture guide image. In addition, because an angle detection sensor is arranged in the body of the ultrasonic probe, the puncture adaptor has no electrical machinery. Therefore this puncture adaptor can be disinfected and sterilized without concern for breakage or electric leakage caused by body fluids or heat. In addition, because the fabrication cost of the puncture adaptor can be lower than one having sensor, it is possible to treat the adaptor as disposable. Furthermore because read wires for sensor signals are provided in the probe body, it is not necessary that a connecting device be provided outside the probe. Because a cable for the sensor to the diagnostic apparatus body is united with a probe cable for transducers, there is no operability complication caused by an increasing number of cables when the puncture adaptor is used.
  • Furthermore, in the above explanation of this exemplary embodiment, because of noncontact sensing between the magneto metric sensor and the magnetic elements, the magneto metric sensor 17 a can be provided inside the case of the probe body 11 c. In this case, the surface of the probe body 11 c can be formed without irregularities. So a probe washing operation is easy. Because of noncontact sensing, in a case that fluid and tissues of object adhere on the surface of the probe body, there is no adverse effect on sensing.
  • Furthermore, in the above explanation of this fourth exemplary embodiment, it is not necessary that a plurality of magneto metric sensors be provided on the probe body 11 c. So the cost of fabricating read wires and connecting devices to the sensor can be lower than the case of using more sensors.
  • Numerous variations of the present invention are possible in light of the above description. It is therefore to be understood that the invention as claimed can be practiced other than is specifically described herein.
  • For example, in above explanation of exemplary embodiments, sensors detecting the slider is magneto metric sensors or photo sensors. However, it is needless to say that electromagnetic induction sensors, electro capacitance sensors or an ultrasound sensors can be adaptable by appropriate change.
