An improved surgical ligating instrument has been invented. The improvements comprise crimping means having canted jaws and advancing means having a clip actuator, said actuator having a first and second pawl in alternate relationship. A surgical ligating instrument has also been invented. The instrument comprises

Surgical ligating instrument

A nonmetallic surgical clip having two separate and noncontiguous parts is decribed. Each part contains an arm, and means for approximating the cooperating surfaces of the two arms. The clip is useful in ligating a blood vessel, e.g. an artery. P

Nonmetallic surgical clip

An improved surgical instrument is described. The instrument comprises a housing. The housing has a handle for activating a force, and a link for translating the force. The instrument also comprises a probe. The probe has jaws or an anvil for holding a single wound closure element, a movable crimp bar for crimping the single closure element in the jaw or anvil, the proximal end of the crimp bar being connected to the distal end of the link, a spring for advancing a plurality of wound closure elements, and an injector for loading a single wound closure element, from the plurality, into the jaws or onto the anvil. The improvement comprises the link indirectly connected to the spring and the injector to integrally effect the crimp bar, spring and injector. The surgical instrument can be a ligating instrument.

Surgical instrument

An improved nonmetallic surgical clip having two separate arms joined together at an apex is disclosed. The improvement comprises a weakened portion and a bend in at least one arm. The bend is at the weakened portion. The amount of the bend is such that at least a part of one arm is in an essentially parallel relationship with at least a part of the other arm.

An improved surgical ligating instrument has been invented. The improvements comprise a crimping mechanism having canted jaws and an advancing mechanism having a clip actuator, said actuator having a first and a second pawl in alternate relationship. A surgical ligating instrument has also been invented. The instrument comprises a. a housing having a force activating and translating mechanism; b. a loading mechanism having an injector, the terminal end adjacent a single clip; c. an advancing mechanism having a pair of aligned members, the initial end of the members contained in the housing and the terminal end containing jaws; a clip actuator rotatably mounted adjacent the initial end of the jaws; a spring, a pusher at the terminal end of the spring, and a plurality of clips, the rearmost clip adjacent the pusher and the frontmost clip contained by the actuator; and d. a crimping mechanism having a crimp bar.
