    • An electrocautery surgical device includes a battery power source and radio-frequency signal generating circuitry electrically coupled to the battery power source and operable to deliver power to an electrosurgical forceps. The radio-frequency signal generating circuitry includes a transformer having a primary winding and a secondary winding. The primary winding includes first and second primary sub-windings. At least one switching component is electrically coupled to the first and second primary sub-windings and is operable to switch between engaging the first primary sub-winding and engaging the second primary sub-winding such that a current flows through the first and/or second primary sub-windings. The first and second primary sub-windings have a different number of turns such that the radio-frequency signal generating circuitry produces a different impedance value depending on which one of the first and second primary sub-windings is engaged.
    • 电烙术手术装置包括电池电源和电耦合到电池电源的射频信号发生电路,并可操作以将电力传送到电外科钳子。 射频信号发生电路包括具有初级绕组和次级绕组的变压器。 初级绕组包括第一和第二初级次级绕组。 至少一个开关部件电耦合到第一和第二初级副绕组,并且可操作以在接合第一初级副绕组和接合第二初级副绕组之间切换,使得电流流过第一和/或第二副绕组 初级次级绕组。 第一和第二初级次级绕组具有不同的匝数,使得射频信号发生电路根据第一和第二主次级绕组中的哪一个接合而产生不同的阻抗值。

    • An anti-tangling device includes a headphone cord having a distal end, a male signal plug at the distal end, a proximal end, and at least one earphone at the proximal end. Each of the plug and the earphone has first or second parts of a two-part connection device. The two-part connection device removably secures the plug and the earphone to one another. In an embodiment, the plug is the first part and the earphone has a plug-in portion as the second part. The plug-in portion defines a female port shaped to removably secure the plug therein and, when secured, forms a continuous loop with the cord, the plug, and the earphone. The plug-in portion can be integral with or removably attached to the earphone. The first and second parts can be a magnet and a magnetized piece, a hook-and-loop type fastener, or parts of a press-fit snap fastener.
    • 防缠结装置包括具有远端的耳机线,在远端处的公信号插头,近端和在近端的至少一个耳机。 插头和耳机中的每一个具有两部分连接装置的第一或第二部分。 两部分连接装置可拆卸地将插头和耳机彼此固定。 在一个实施例中,插头是第一部分,并且耳机具有作为第二部分的插入部分。 插入部分限定了形成为可拆卸地将插头固定在其中的阴端口,并且当被固定时,与电线,插头和耳机形成连续的环路。 插入部分可以与耳机一体地或可拆卸地附接到耳机。 第一部分和第二部分可以是磁体和磁化件,钩环式紧固件或压配合扣件的部件。
