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.
