    • The invention relates to a surgical device for guiding at least two sewing threads through the marginal area of a tissue opening which is present especially in an artery of an individual, the opening optionally having been produced by cutting. The device comprises a bar-shaped needle and thread guiding device having a needle transfer area at the proximal end of the device, a needle receiving area at the distal end of the device, and arranged thereinbetween an intermediate area for receiving the marginal area of the tissue opening. The needle transfer area, the intermediate area and the needle receiving area are rigidly interlinked. The bar-shaped needle and thread guiding device can be closed by an elongate outer member which positively surrounds the intermediate area. The outer member can be displaced in relation to the bar-shaped needle and thread guiding device in the longitudinal direction thereof, thereby releasing the intermediate area. The needle transfer area, towards the distal end of the device, and the elongate member, in the area towards the proximal end of the device, have end faces facing each other.
    • 本发明涉及一种用于引导至少两条缝合线穿过组织开口的边缘区域的手术装置,其特别地存在于个体的动脉中,所述开口可选地通过切割产生。 该装置包括条形针和引导装置,该装置在装置的近端处具有针传送区域,在装置的远端处具有针接收区域,并且布置在其间用于接收装置的边缘区域的中间区域 组织开放。 针传送区域,中间区域和针接收区域是刚性地相互连接的。 杆形针和引导装置可以由正向包围中间区域的细长外部构件封闭。 外部构件可以相对于杆形针和引导装置沿其纵向方向移位,从而释放中间区域。 朝向装置的远端的针传送区域和细长构件在朝向装置的近端的区域中具有彼此面对的端面。

    • A clamping arrangement for clamping a cylindrical shaft of a tool in a dental handpiece includes a clamping sleeve having resilient tongues for gripping the cylindrical shaft and being capable of being moved radially outward by an adjustable plunger to release the shaft. In order to achieve a largely wear-free tool guidance, the tool shaft is held at least at its distal end of the tool in a guide bushing, which is firmly joined to the hollow shaft. The guide contains an arrangement which enables axial mobility of the plunger, prevents twisting of the plunger so as to enable transmission of the force between the plunger and a manipulator which actuates the plunger.
    • 用于夹紧牙齿手柄中的工具的圆柱形轴的夹紧装置包括具有用于夹紧圆柱形轴的弹性舌片并且能够通过可调节柱塞径向向外移动以释放轴的夹紧套筒。 为了实现大部分无磨损的工具引导,工具轴至少在其工具的远端处被保持在与中空轴牢固连接的引导衬套中。 引导件包括能够使柱塞轴向移动的布置,防止柱塞扭转,以便能够在柱塞与致动柱塞的操纵器之间传递力。
