摘要：
An apparatus and method for manufacturing small diameter ultrasonic probes (1) capable of vibrating in a transverse mode that can be used in ultrasonic tissue ablation. The apparatus includes a die (20), a syle puller (30) which is used to engage a functional end of the medical device, and a die room puller (40) which is used to draw the medical device through the die. The die (20) includes a bell-shaped lead-in (22) on a front side (24) of the die (20) and a bell-shaped lead-in (23) on a back side (25) of the die allowing for reversal of the direction of the draw. The method of manufacturing includes heat treating a large diameter medical device, drawing the large diameter device through a die (20) and reversing the draw of the medical device through the die to provide a medical device having a varying diameter along a length of the device. The method is repeated until a final diameter is reached.
摘要（中）：
一种用于制造能够用于超声波组织消融的横向模式的小直径超声波探头（1）的装置和方法。 该装置包括用于接合医疗装置的功能端的模具（20），用于接合医疗装置的功能端的提取器（30），以及用于通过模具吸引医疗装置的模具室拉拔器（40）。 模具（20）包括在模具（20）的前侧（24）上的钟形引入件（22）和模具的背面（25）上的钟形引入件（23） 允许反转方向的画面。 制造方法包括对大直径医疗装置进行热处理，通过模具（20）拉伸大直径装置并且通过模具反转医疗装置的牵引，以提供具有沿装置的长度的变化的直径的医疗装置 。 重复该方法直到达到最终直径。
