摘要： A trocar for use in surgical procedures including a cannula for maintaining a sealed working channel in a body wall and an obturator which creates the working channel through the body wall while protecting patients and medical personnel from harm is disclosed. A cannula converter which can be employed with the trocar to enable a surgeon to use surgical instruments having a smaller outer diameter than the inner diameter of the cannula without deflating a body cavity is further disclosed. A site stabilizer which can be used with the trocar to prevent the cannula from being inadvertently withdrawn from the body cavity during a surgical procedure is also disclosed.
摘要翻译：公开了一种用于外科手术的套针针，包括用于在体壁中保持密封工作通道的插管和闭孔器，其在保护患者和医护人员免受伤害的同时通过身体壁产生工作通道。进一步公开了套管转换器，其可与套管针一起使用以使得外科医生能够使用具有比插管的内径更小的外径的外科器械，而不会使体腔膨胀。还公开了一种位置稳定器，其可以与套针针一起使用以防止套管在外科手术过程中不经意地从体腔抽出。

摘要： A water extraction cleaner comprises a system for delivering clean solution to a surface to be cleaned, a system for extracting dirty solution and air from such a surface, and a housing supporting the delivery system and the extraction system. The housing defines a recess for receiving a pair of tanks, an upright front surface of the recess being complementary to upright rear surfaces of the tanks. The housing is also provided with a pivot surface spaced from the upright surface of the recess and engageable by lower end portions, the pivot surface being formed and disposed to hold the upright surfaces of the tanks in snug engagement with the upright recess surface. Each of the tanks may be mounted on the housing by tilting the tank to insert the lower end portion thereof into the recess and then rotating the tank to an upright position about the pivot surface. The delivery system includes an inlet on the housing disposed to receive clean solution from one of the tanks when it is received in the recess in the upright position. The extraction system includes an outlet on the housing disposed to deliver dirty solution and air to the other of the tanks when it is received in the recess in the upright position. A detent arrangement is provided to removably secure the tanks on the housing in these operative positions, and the clean-solution tank includes a valve mechanism automatically actuated to permit flow from the tank when it is in its operative position.
摘要翻译：一种提水清洁器包括用于将清洁溶液输送到要清洁的表面的系统，用于从这种表面抽取脏溶液和空气的系统，以及支撑输送系统和提取系统的壳体。壳体限定用于接收一对罐的凹部，凹部的直立前表面与罐的直立后表面互补。壳体还设置有与凹部的直立表面间隔开并可由下端部分接合的枢转表面，该枢转表面被形成和设置成将罐的直立表面与直立凹陷表面贴合地接合。每个罐可以通过倾斜罐来安装在壳体上，以将其下端部分插入凹部中，然后将罐旋转到围绕枢转表面的直立位置。输送系统包括壳体上的入口，该入口设置成当容器中的一个容纳在直立位置的凹部中时从其中一个容器接收干净的溶液。提取系统包括壳体上的出口，该出口设置成当其处于直立位置的凹槽中时将污染的溶液和空气传送到另一个罐中。提供了一种制动装置，用于在这些操作位置可拆卸地将箱体固定在壳体上，并且清洁溶液箱包括一个自动启动的阀门机构，以允许当罐处于其工作位置时从罐中流出。

摘要： An accessory tool according to the present invention comprises a recovery tank assembly for removing fluid and dirt from a surface to the cleaned and storing the recovered fluid and dirt. The recovery tank assembly comprises a suction nozzle in fluid communication with a recovery tank. The accessory tool further comprises a fan/turbine assembly including a turbine-driven suction fan for generating suction at the suction nozzle, which draws liquid and air into and through the accessory tool. The turbine-driven suction fan can be magnetically coupled with the turbine. The accessory tool can further comprise a fluid dispensing assembly for storing and distributing fluid to the surface to the cleaned. The fluid dispensing assembly can comprise a turbine-driven fluid pump. The accessory tool can further comprise an agitator assembly that can be moved from a use to a non-use orientation to allow the accessory tool to alternately be used for scrubbing the surface to the cleaned and for extracting fluid from the surface to be cleaned. The recovery tank can further comprise a rotating outlet conduit with an inlet opening that will have an upward orientation when the recovery tank is tilted.
摘要翻译：根据本发明的附件工具包括一个用于将流体和污垢从表面移除到清洁的回收罐组件，并且储存回收的流体和污垢。回收罐组件包括与回收罐流体连通的吸嘴。附件工具还包括风扇/涡轮机组件，其包括用于在吸嘴处产生吸力的涡轮驱动的吸入风扇，其将液体和空气吸入并通过附件工具。涡轮驱动的吸风机可以与涡轮机磁耦合。附件工具还可以包括用于将流体存储并分配到清洁的表面的流体分配组件。流体分配组件可以包括涡轮驱动流体泵。附件工具还可以包括搅拌器组件，该搅拌器组件可以从使用方向移动到非使用方向，以允许附件工具交替地用于将表面擦洗到被清洁的并且从待清洁表面提取流体。回收罐可以进一步包括具有入口开口的旋转出口管道，当回收罐倾斜时，其将具有向上的取向。
