Abstract
The disclosed device can hold, or effect relative longitudinal movement between, two members of a medical instrument, such as an instrument used for fastening two hollow organs together. The device may comprise a handle member having a longitudinal guide defining a line of travel and a longitudinal groove having a detent catch therein; a longitudinally spring-biased moving member slidable within the longitudinal guide and having pawl receiving slots along a line parallel with the line of travel; and a transversely and rotationally spring-biased driving trigger member comprising a pawl proximate to the moving member and adapted to engage the pawl receiving slots when aligned therewith, and a fulcrum member movable within the groove and adapted to be releasably captured by the detent, the driving trigger member being rotatable about the fulcrum member to cause the pawl to engage or disengage the pawl receiving slots.
