摘要： A safety-shielded trocar having an obturator with a linear cutting edge surface defining a base width substantially less than the diameter of the safety shield is disclosed. When the trocar is inserted through tissue, the tissue dilates from the width of the linear incision to accommodate the size of the safety shield of the trocar, thus making it possible to provide an access opening greater than the incisional width made by the linear cutting edge surface of the obturator. In a preferred embodiment, the safety shield has a shield tip region which is asymmetric to facilitate the dilation of the tissue as the trocar is inserted.

摘要： Methods for control of excessive corrosion in wet process phosphoric circuits are effected by oxidation of reduced ion species in the acid with maintenance of EMF value of the acid above about 190 millivolts (S.C.E. reference) through the digestion circuit. Supplementary monitoring is by a ceric red-ox titration procedure. In one embodied form, the present invention is utilized to control corrosion in a phosphoric acid plant digestion system (and subsequent processing equipment) operating by a dihydrate (gypsum) process even when such a process employs a calcined western U.S. phosphate ore feed from a relatively highly carbonaceous ore. The invention is also applicable for treating wet process phosphoric acid in phosphoric acid plants having a digester system operating by a hemihydrate process. In a presently preferred embodiment, additions of manganese dioxide to a primary digester in a sufficient amount effective to achieve an EMF value over about 190 millivolts will significantly control the occurrence of excessive corrosion in phosphoric acid circuits. In yet another preferred embodiment, an oxygen autoclave oxidation is used to oxidize the reduced ion species present in the acid to inhibit corrosion.
摘要翻译：用于控制湿法磷酸回路中过度腐蚀的方法是通过在酸中氧化还原的离子物质来实现的，其中通过消化回路维持高于约190毫伏（S.C.E.参考）的酸的EMF值。补充监测是通过氧化铈滴定法。在一个实施形式中，本发明用于控制在二水合物（石膏）方法中操作的磷酸设备消化系统（和随后的加工设备）中的腐蚀，即使这种方法使用来自相对的高含碳矿石。本发明也适用于在具有通过半水合法处理的蒸煮器系统的磷酸设备中处理湿法磷酸。在目前优选的实施方案中，以足以实现大约190毫伏的EMF值的足够量的一次蒸煮器添加二氧化锰将显着控制磷酸回路中过度腐蚀的发生。在另一个优选的实施方案中，使用氧气高压釜氧化来氧化存在于酸中的还原离子种类以抑制腐蚀。

摘要： Systems and associated methods for sensing and indicating when a wide range of tissue is adequately cauterized and/or sealed by an electrosurgical instrument. The system indirectly monitors the current flowing through the tissue and determines the adequacy of tissue cauterization or sealing of vessel(s) by monitoring when the current is stable or nearly stable (i.e. when the current is constant). The system may also indicate a predetermined time that current is applied through the tissue and control the flow of energy through the tissue.

摘要： A surgical instrument, such as an electrical ablation device, includes an elongate member having therealong disposed a first electrode extending along an axis. A first expandable portion extends along the axis and defines a first perimeter of the first electrode and has an associated first diameter with respect to the axis. The first expandable portion includes a first framework selectively expandable to transition the first expandable portion from a contracted state to an expanded state. The first framework is selectively contractible to transition the first expandable portion from the expanded state to the contracted state. When the first framework is expanded, the first diameter is expanded and the first expandable portion is transitioned from the contracted state to the expanded state. When the first framework is contracted, the first diameter is contracted and the first expandable portion is transitioned from the expanded state to the contracted state.

摘要： An apparatus for treating tissue in a tissue treatment region. The apparatus can comprise an electrode ring having an interior perimeter and an electrode probe having a proximal end and a distal end. The distal end of the electrode probe can be structured to axially translate relative to the interior perimeter of the electrode ring. The electrode ring and the electrode probe can be operably structured to conduct current therebetween when at least one of the electrode ring and the electrode probe is energized by an energy source. Further, the energy source can be a Radio Frequency (RF) energy source, a pulsed energy source, an irreversible electroporation energy source, or a pulsed irreversible electroporation energy source. A current from the energy source can be selected to non-thermally ablate tissue in the tissue treatment region.

摘要： A surgical instrument, such as an endoscopic or laparoscopic instrument, includes an ablation device. The ablation device includes an elongate member having first and second channels. First and second probes are disposed within the respective first and second channels. The first and second probes each define a central axis. The first and second probes each have substantially straight distal ends protruding from the distal ends of the respective first and second channels. The substantially straight distal ends define an outer surface. First and second electrodes are attached to a portion of the outer surface of the substantially straight distal ends of the respective first and second probes. The first and second electrodes are positioned in juxtaposed relationship with the central axis of the first and second probes. A distance between the first and second electrodes is adjustable by rotating at least one of the first and second probes about the respective central axis of the at least one of the first and second probes.
