    • Highly flexible liposuction cannulas are constructed of metal and plastic, with the metal cannulas having diameters of between 2.0 and 3.5 mm, and with the plastic cannulas having diameters greater than 3.5 mm (i.e., 3.5 to 9.0 mm). These long shaft flexible cannulas, when utilized in combination with a reinforced neck, allow the cannula point of entry to act as a fulcrum (with an optional interposed insert) and in concert with the surgeon's guiding hand to deflect the cannulas. The cannula tip is preferably highly beveled with an adjacent set of three openings, and the cannula easily penetrates fibrous fat and may reach fast deposits relatively distant from the entrance wounds. The long shaft, highly flexible, reinforced swan neck cannulas move in an easily controllable manner within the subcutaneous tissue below the dermal envelope in an arciform fashion. Benefits include a reduced need to move a patient's body position intraoperatively. The swan neck has been reinforced to provide the needed additional stability at handle/shaft junction to help the surgeon increase leverage on the cannula shaft. The long, flexible plastic cannula shafts are provided central removable metal “memory” reinforcing wires of varying thicknesses along the length thereof which allow controlled rigidity of the long plastic shafts, and enable the cannulas to be bent into a semi-circle without breaking and yet return to their original shape. Removing of the memory wire during autoclaving eliminates thermal damage at plastic/metal interfaces.
    • 高度灵活的吸脂插管由金属和塑料构成,金属插管的直径为2.0至3.5毫米,塑料插管直径大于3.5毫米(即3.5至9.0毫米)。 当与加强的颈部组合使用时,这些长轴柔性插管允许插管入口点作为支点(具有可选插入的插入件),并与外科医生的引导手协调以偏转插管。 套管尖端优选地具有相邻的三个开口的高度倾斜,并且套管容易地穿透纤维状脂肪并且可能达到相对远离入口伤口的快速沉积物。 长轴,高度灵活,加强的天鹅颈插管以一种弧形方式在皮肤信封下方的皮下组织内以容易控制的方式移动。 优点包括减少在术中移动患者身体位置的需求。 天鹅颈已经被加强,以便在手柄/轴结处提供所需的额外的稳定性,以帮助外科医生增加套管轴上的杠杆作用。 长而柔性的塑料插管轴沿其长度设置有不同厚度的中央可拆卸金属“记忆”加强线,其允许长塑料轴的受控刚度,并且使套管弯曲成半圆而不破裂 回到原来的形状。 在高压灭菌过程中取出内存线可消除塑料/金属界面的热损伤。

    • Positive or negative biofeedback is provided by an apparatus using jets of fluid, such as a compressed gas, directed at a targeted area of a body to produce a positive or negative tactile sensation. A stimulus unit is connected to a fluid supply and is positioned on the body, such as the abdomen or back. A sensor unit connected to the stimulus unit is activated, such as by relaxed muscle position or other behavior, which then activates the stimulus unit to open release valves and deliver bursts of small jets of gas to the body. The sensor unit may be remote from the stimulus unit, whereby signals are sent remotely through a control unit to the stimulus unit to activate the release valves.
    • 正或负的生物反馈由使用针对身体目标区域的流体射流(例如压缩气体)产生正或负触觉的装置提供。 刺激单元连接到流体供应器并且被定位在身体上,例如腹部或背部。 连接到刺激单元的传感器单元被激活,例如通过放松的肌肉位置或其他行为,其然后激活刺激单元以打开释放阀并将小的气流喷射到身体。 传感器单元可以远离刺激单元,由此将信号通过控制单元远程发送到刺激单元以激活释放阀。

    • Biocompatible materials are propelled at the skin with sufficient velocity to cause desired resurfacing of skin layers to the desired penetration depth. The materials, such as dry ice or water ice, are harmonious with the human body and thus eliminate foreign body reactions. Various materials may be used in combination, including local anesthetics and vasoconstrictors in solid or liquid form. The biocompatible solid or liquid particles are suspended in a cold carrier fluid and propelled through an insulated delivery system to the surface of the skin. The treatment of diseased skin lesions may be accomplished using the present invention as a drug delivery system.
    • 生物相容性材料以足够的速度在皮肤上推进,以使皮肤层的所需表面重新形成所需的穿透深度。 材料如干冰或水冰与人体和谐,从而消除异物反应。 可以组合使用各种材料,包括固体或液体形式的局部麻醉剂和血管收缩剂。 生物相容性固体或液体颗粒悬浮在冷载体流体中,并通过绝缘递送系统推进到皮肤表面。 可以使用本发明作为药物递送系统来治疗患病的皮肤损伤。
