摘要： An ultrasonic probe has an elongate tubular member and an imaging ultrasonic transducer pivotally mounted proximate the distal end of the tubular member. Reciprocating pivotal motion of the ultrasonic transducer is effected to facilitate scanning. A first cable attached to the imaging ultrasonic transducer effects pivoting thereof in a first direction and a second cable attached to the imaging ultrasonic transducer effects pivoting thereof in a second direction. A linear motor is attached to the first cable for pulling the first cable to effect pivoting of the ultrasonic transducer in the first direction and a tension means is attached to the second cable for pulling the second cable when the linear motor ceases pulling the first cable to effect pivoting of the ultrasonic transducer in the second direction.

摘要： A transducer is pivoted by a linear motor having an electrical coil as the reciprocally moving member. The coil is in a plane orthogonal to the lines of magnetic flux between opposed permanent magnets of opposite polarity affixed to the probe case, providing efficiency. A mechanical linkage between the linear motor electrical coil moving member and the transducer which is forced in pivoting motion transmits only axial force, and not torque, by employing a ball and socket joint at one end of a crankshaft. Electrical connections to the electrical coil are facilitated through springs which additionally mechanically bias the reciprocal movement of the coil. Electrical connections to the pivoting transducer are facilitated through a helical coil wrapping the pivot shaft. These electrical connections accomodate mechanical motions within the probe. A bellows-fold cylindrical air bladder is positioned within the fluid chamber of the probe to allow for thermally-induced changes in fluid volume.

摘要： An ultrasonic prostate probe assembly is disclosed, characterized by the ultrasonic transducer being carried upon a gimbal cup which is rotatably mounted to the probe assembly to allow selection of multiple sector scan directions during operation of the probe. The transducer is pivoted via a spring biased cable linkage connected to a linear motor having an electric coil as the reciprocating moving member. Selective rotation of the gimbal cup is effectuated by manipulation of an additional cable linkage extending axially through the probe assembly. The use of multiple sector scan directions allows improved identification and sizing of problematic body tissue in applications such as prostate applications where space constraints prevent manipulation of the probe into differing scanning positions.
摘要翻译：公开了一种超声波前列腺探针组件，其特征在于，超声波换能器承载在万向杯上，万向节杯可旋转地安装到探针组件，以允许在探针操作期间选择多个扇形扫描方向。传感器通过连接到具有作为往复运动构件的电线圈的线性电动机的弹簧偏置电缆连杆枢转。万向杯的选择性旋转通过操纵沿轴向延伸穿过探针组件的另外的缆线连杆来实现。使用多个扇区扫描方向允许改进在诸如前列腺应用的应用中有问题的身体组织的识别和尺寸调整，其中空间限制阻止探针操纵到不同的扫描位置。

摘要： An ultrasonic transducer probe is provided, in which the transducer is oscillated by a crank shaft for sector scanning. The crank shaft is driven by a motor having a moving magnet stack assembly in a tubular set of electromagnetic coils. The motor also moves a bimetallic pin through a position sensor coil so that the position of the transducer is represented by the detected inductance change of the coil.

摘要： An ultrasonic transducer probe is provided which utilizes a pivoting transducer to perform an ultrasonic sector scan. The transducer and its drive mechanisms are contained within a fluid chamber. A portion of the wall of the fluid chamber includes a flexible bellows, which expands and contracts as pressure and temperature changes alter the fluid volume, thereby altering the fluid chamber volume.
