## Abstract

A forceps for applying metal clips for surgical use is disclosed, the clips being applied to blood vessels to shut off flow through the blood vessel, the forceps being capable of being opened to a much greater extent than heretofore, by shifting the position of a spring which normally opens the forceps to the extent necessary for picking up the clip to be applied.

## Claims

### Claim 1

Forceps for moving a clip into engagement with a blood vessel comprising
first and second arms pivotally connected at their distal ends and having handle means at their proximal ends,
said arms having clip deforming jaws extending from each arm distal to the pivotal connection,
a leaf spring pivotally connected to said first arm intermediate the arms of the spring,
the distal end of the spring being alignable with said first arm and when so aligned the proximal end is urged by the spring to bias said second arm away from said first arm,
slots in said first and second arms proximal to the pivotal connection therebetween which are engageable with the distal end of said spring when said spring is substantially aligned with said first arm whereby said jaws are properly spaced to engage an undeformed clip therebetween,
said slots being located such that said jaws are closeable to deform the clip when said spring is engaged in said slots.
