Abstract
The present invention relates to an improved reciprocating jaw type hemostatic clip applier or ligator. The improved apparatus is provided with an improved camming mechanism which interfaces with the jaws to cam the jaws closed and which is designed to maintain its alignment with respect to the jaws to prevent misalignment of the jaws during closure and malformation of clips. The improved apparatus is also provided with a lockout mechanism which prevents the jaws from being closed once the last clip has been formed and released from the instrument.
