A device for cutting a suture thread, comprising:

a handle;
a stationary external element having a channel at the distal end, and a proximal end connected to said handle, said channel is fitted and shaped for holding a suture thread;
a movable cutter having a cutting edge, partially inserted into said handle, said cutting edge is configured to move between a first position and a second position in said channel;
wherein in said first position the suture thread is retained within the channel and in said second position the suture thread is cut;
and
a force-activated lever, wherein said lever is configured to selectively move said movable cutter between said first position and said second position upon force exertion on said lever;
wherein said lever includes a longitudinal opening, and wherein movement of said longitudinal opening in a proximal direction relative to a pin in the handle, upon force exertion on said lever, generates a movement of said movable cutter in a distal direction.
