    摘要： A method for cryogenic treatment of a lesion which includes the steps of delivering a fluorochemical liquid to the lesion, placing at least one cryoprobe into the lesion, and circulating cryogenic fluid through the cryoprobe, the cryogenic fluid causing an ice ball to form in a vicinity around the cryoprobe, wherein the ice ball obliterates at least a portion of the lesion. The fluorochemical liquid is utilized to augment the cryosurgical procedure and is perfused or injected into and/or around the lesioned site prior and/or during the application of a cryoprobe to the site. In one embodiment of the invention, the fluorochemical liquid acts as a contrast agent to enhance real-time medical imaging of the lesioned area and modifies the environment in and around the lesioned area. In another embodiment of the invention, the fluorochemical liquid augments cryosurgical procedures by controlling the size and shape of ice balls formed during the cryosurgical procedures. In this embodiment, a fluorochemical liquid with a properly chosen thermal conductivity and freezing point is utilized. Depending on the thermal properties chosen, the liquid either augments freezing of the target area and/or promotes thermal conduction to freeze larger areas, or limits the freezing of the target area and reduces thermal conduction. In a non-cryoprobe embodiment, the liquid is cooled to a temperature below the freezing point of the biological tissue. The cooled liquid is then infused into or around the cystic lesion to produce ablation.

    摘要翻译： 一种用于对病变进行低温处理的方法，包括以下步骤：将含氟化学液体输送到损伤部分，将至少一个冷冻探针放入损伤部分，并使低温液体循环通过冷冻探针，使低温流体在附近形成冰球 围绕冷冻探针，其中冰球消除至少一部分病变。 使用含氟化合物液体来增加冷冻手术的程序，并且在使用冷冻探针之前和/或期间向该部位灌注或注入损伤部位和/或周围。 在本发明的一个实施方案中，含氟化合物液体用作造影剂，以增强损伤区域的实时医学成像并改变损伤区域内和周围的环境。 在本发明的另一个实施方案中，含氟化合物通过控制在冷冻手术过程中形成的冰球的尺寸和形状而增加了冷冻手术。 在该实施例中，利用具有适当选择的导热性和凝固点的含氟化合物液体。 根据所选择的热性质，液体或者增加目标区域的冷冻和/或促进热传导以冻结较大的区域，或限制目标区域的冷冻并减少热传导。 在非冷冻探针实施方案中，将液体冷却至低于生物组织凝固点的温度。 然后将冷却的液体注入囊性病变中或周围，以产生消融。

    摘要： A bed having a torque-compensated parallelogram lifting arm arrangement. The bed has a subframe vertically adjustable by the parallelogram lifting arm arrangement and thereby retains a level relationship at all height adjustment levels.An articulated mattress support surface is provided, which is formed by articulated pivotally interconnected head or back, seat, thigh and leg sections mounted on the level vertically adjustable subframe. The seat section is double-pivoted, and enables simple and effective Trendelenburg and Reverse Trendelenburg positioning independent of any position of the height-adjustable supporting subframe. The seat, thigh, and head sections are articulated by cam and cam follower drive arrangements. Selective pivot defeat means are provided to enable selective pivotal lowering of the thigh and head or back sections without pivoting the seat section, and independent of the supporting subframe position, enabling simple and effective hyperextension positioning. The back and thigh sections may be pivoted up and down to at and above horizontal by patient control; other movements and positioning are nurse-controlled by a foot end mounted nurse control panel. A cantilever bumper, having wall engaging rollers, is pivotally mounted at the head end of the bed on the base, and is automatically lowered when the bed height is lowered to assure spaced positioning of the bed from a wall. The bumper self-retains its set angular position by frictional action at its pivot mounting connection with the base. Sockets are provided on the vertically adjustable always level subframe at the corners and midsection for mounting IV rods, fracture frames, patient control pendant holders, etc. Vertical height adjustment and all mattress support surface articulation action can be selectively effected by electric motor control or hand crank.

    摘要： A snowball maker has opposed inner and outer cup-like shells which interfit to compact snow into a ball. The inner shell deforms, within outer shell, upon full insertion substantially to encircle the snow within the two shells. Upon separating the shells, the inner shell resiliently opens to its original shape for ready release of the compacted ball of snow.
