摘要： A surgical stapling device has an elongated body and a removable loading unit and a securing structure for securing the loading unit onto the elongated body. Guiding ramps guide the movement of the loading unit as it is mounted onto the elongated body. A movable yoke secures the loading unit onto the elongated body. A sensor mechanism is engaged by the loading unit and moves with the securing structure. The locking structure has a first position for blocking movement of the sensor mechanism and preventing removal of the loading unit. The locking unit has a second position for allowing the loading unit to be removed from the device.

摘要： A system for movably positioning a first member relative to a second member. The system has a hole in the first member and a coiled spring/plunger member positioned in the hole. The coiled member has a section that extends out of the hole that does not possess significant spring properties and thus can act as a plunger. The plunger section of the coiled member can be moved in and out of an aperture to the hole without risk of damage. Thus, the second member can be moved relative to the first member by compressing the coiled member or moving away from the coiled member and, the coiled member can position the second member relative to the first member while at rest.
摘要翻译：一种用于相对于第二构件可移动地定位第一构件的系统。该系统在第一构件中具有孔和位于孔中的盘簧/柱塞构件。螺旋构件具有延伸出孔的部分，其不具有显着的弹性，因此可以用作柱塞。螺旋构件的柱塞部分可以进入孔中并从孔中移出到孔中，而没有损坏的风险。因此，第二构件可以通过压缩螺旋构件或从线圈构件移开而相对于第一构件移动，并且线圈构件可以在静止时相对于第一构件定位第二构件。

摘要： A reversible magazine catch assembly has a housing, a movable mounting pin and a coiled spring. The housing has a spring channel generally perpendicular to and intersecting a pin hole, and a magazine locking rib. The spring channel is formed by drilling three parallel holes into the housing at different directions to provide lateral support for the coiled spring. The spring biases the housing relative to the pin and forms a slidable friction hold of the pin. The pin has ledges that interact with the spring and housing to prevent it from being pushed out of the housing.
摘要翻译：可翻转的弹匣夹具具有壳体，可移动安装销和螺旋弹簧。壳体具有大致垂直于销孔和与销孔相交的弹簧通道，以及弹匣锁定肋。弹簧通道是通过在不同的方向上将三个平行的孔钻入壳体而形成的，为螺旋弹簧提供横向支撑。弹簧相对于销偏压壳体并形成销的可滑动的摩擦保持。销具有与弹簧和壳体相互作用的壁架，以防止其被推出外壳。
