摘要： A bending tool for use with a human hand for bending the distal extremity of a guide tube of a medical device having a needle assembly slidably mounted in the guide tube. The distal extremity of the guide tube has a tip. The bending tool is comprised of a shaft sized so that it is adapted to be grasped by the human hand to serve as a handle. The shaft has proximal and distal extremities and a longitudinal axis. A bending construction is mounted on the distal extremity of the shaft and provides a curved bending surface having width and a length and having a proximal and a distal extremity and extending at an angle with respect to the longitudinal axis. The bending construction also has an abutment surface at the distal extremity of the curved surface and extending generally perpendicular to the curved surface. The abutment surface has a hole therein extending in a direction generally perpendicular to the abutment surface and is sized so that it is adapted to receive the tip of the guide tube with the guide tube engaging the curved surface to permit bending of the guide tube by a swinging movement of the shaft in a direction at right angles to the abutment surface.
摘要翻译： 一种用于人用手弯曲医疗装置的导管的远端的弯曲工具，其具有可滑动地安装在引导管中的针组件。 导管的远端具有尖端。 弯曲工具包括轴，其尺寸使得其适于被人的手抓住以用作手柄。 轴具有近端和远端以及纵轴。 弯曲结构安装在轴的远端上，并且提供具有宽度和长度的弯曲弯曲表面，并且具有近端和远端并且相对于纵向轴线以一定角度延伸。 弯曲结构还在弯曲表面的远端处具有邻接表面并且大致垂直于弯曲表面延伸。 邻接表面具有在大致垂直于邻接表面的方向上延伸的孔，并且其尺寸设计成使得其适于接收引导管的尖端，导管与弯曲表面接合以允许引导管弯曲 轴在与邻接表面成直角的方向上摆动。

摘要： A tissue ablation apparatus for minimally invasive treatment for disorders of the upper airway by the treatment of soft tissues in the upper airway comprising a hand-held device adapted to be held by the human hand. Radio frequency energy is delivered to the hand-held device. The hand-held device comprises a housing having a handle portion adapted to be grasped by the human hand and a probe portion. At least one guide tube is mounted in the probe portion and has a bore extending therethrough. A carrier block is slidably mounted in the housing relative to the guide tube. At least one needle assembly is mounted in the carrier block assembly and is movable with the carrier block assembly. The at least one needle assembly extends distally of the carrier block and is slidably disposed in the at least one guide tube. A slider is mounted on the housing exterior of the housing for slidable movement longitudinally of the housing and is adapted to be grasped by the thumb of the hand holding the housing. The slider is connected to the carrier block whereby when the slider is moved distally, the carrier block with the needle assembly is moved in the guide tube distally of the guide tube for entrance into the soft tissue.
摘要翻译： 一种用于通过治疗上气道中的软组织来治疗上呼吸道疾病的微创治疗的组织消融装置，包括适于由人手保持的手持装置。 射频能量传送到手持设备。 手持式装置包括壳体，该壳体具有适于由人手抓握的手柄部分和探针部分。 至少一个导管安装在探针部分中并且具有延伸穿过其中的孔。 载体块相对于导管可滑动地安装在壳体中。 至少一个针组件安装在承载块组件中并且可与承载块组件一起移动。 所述至少一个针组件在所述承载块的远侧延伸并且可滑动地设置在所述至少一个引导管中。 滑动件安装在壳体的壳体外部上，用于可滑动地移动到壳体的纵向，并且适于由握住壳体的手的拇指来抓握滑块。 滑块连接到承载块，由此当滑块向远侧移动时，具有针组件的承载块在引导管中在引导管的远侧移动以进入软组织。
