摘要： An apparatus for implementing a skin incision has a torsion spring and a method of assembling the apparatus. The apparatus has a housing having a pair of housing sections, each of the housing section having a base and a plurality of walls. The housing defines an inner space and an exterior. A pivot arm is pivotally mounted to a base of a housing section. The pivot arm is guided between a first position and a second position by a follower in a cam carried by the housing. A torsion spring carried by a spring post is coupled to the arm to exert a spring force on the arm in the first position. The housing has an indentation with a raised level and a lower groove on the base for receiving a portion of the spring post. The opening through the base extends from the lower groove. The spring post has a cylindrical base portion adapted to be received by the indentation in the base and a detent portion. The detent portion has a circular segment detent portion and a turn element accessible from the exterior of the housing. The circular segment detent portion is adapted to engage the raised level of the indentation in the install position and be retained in the lower groove in the loaded position. A trigger mechanism is received in the housing and acts with the pivot arm when activated whereby the arm moves from the first position to the second position due to the spring energy.
摘要翻译： 用于实施皮肤切口的装置具有扭转弹簧和组装该装置的方法。 该装置具有壳体，该壳体具有一对壳体部分，每个壳体部分具有基部和多个壁。 壳体限定内部空间和外部。 枢转臂枢转地安装到壳体部分的基部。 枢转臂在由壳体承载的凸轮中的从动件在第一位置和第二位置之间被引导。 由弹簧支架承载的扭转弹簧联接到臂上，以在第一位置上在臂上施加弹簧力。 壳体具有升高的压痕和底座上的下槽，用于容纳弹簧柱的一部分。 通过基座的开口从下槽延伸。 弹簧柱具有适于被基座中的凹陷接收的圆柱形基部和止动部。 止动部分具有圆形段止动部分和可从壳体的外部接近的转向元件。 圆形段止动部分适于在安装位置接合压痕的升高水平并且在加载位置中保持在下槽中。 触发机构被容纳在壳体中并且当被激活时与枢转臂一起作用，由此由于弹簧能量，臂从第一位置移动到第二位置。
