Surgical instrument usable as a grasper and/or probe
First Claim
1. A surgical instrument usable as a tweezers or as a probe, comprising:
- an elongated arm having a proximal end and a distal end defining a fixed jaw;
a pivotal jaw pivotally mounted to the distal end of said elongated arm to open and closed position with respect thereto;
an actuator arm movably mounted with respect to said elongated arm coupled to said pivotal jaw such that moving said actuator arm in one direction moves said pivotal jaw to a closed position with respect to said fixed jaw, and moving said actuator arm in another direction moves said pivotal jaw to an open position with respect to said fixed jaw;
and a locking arm carried by said elongated arm and manually movable to a locking position for locking said pivotal jaw in its closed position with respect to said fixed jaw.

Abstract
A finger-mountable surgical instrument usable as a tweezers or as a probe, includes a sleeve dimensioned to be received on the outer end of a finger of a user; an elongated arm having a proximal end fixed to the sleeve and a distal end projecting forwardly of the sleeve and defining a fixed jaw; a pivotal jaw pivotally mounted to the distal end of the elongated arm to open and closed positions; an actuator arm movably mounted with respect to the sleeve and coupled to the pivotal jaw such that moving the actuator arm in one direction moves the pivotal jaw to a closed position with respect to the fixed jaw, and moving the actuator arm in another direction moves the pivotal jaw to an open position with respect to the fixed jaw; and a locking arm carried by the sleeve and manually movable to a locking position for locking the pivotal jaw in its closed position with respect to the fixed jaw.

12. A finger-mountable surgical instrument usable as a tweezers or as a probe, comprising:
-
a sleeve dimensioned to be received on the outer end of a finger of a user; an elongated arm having a proximal end fixed to said sleeve and a distal end projecting forwardly of said sleeve and defining a fixed jaw; a pivotal jaw pivotally mounted to the distal end of said elongated arm to open and closed position with respect thereto; an actuator arm movably mounted towards and away from said sleeve and coupled to said pivotal jaw such that moving said actuator arm towards said sleeve moves said pivotal jaw to a closed position with respect to said fixed jaw, and moving said actuator arm away from said sleeve moves said pivotal jaw to an open position with respect to said fixed jaw; a spring normally urging said actuator arm away from said sleeve and, thereby, said pivotal jaw to an open position with respect to said fixed jaw; and a locking arm carried by said sleeve and manually movable to a locking position for moving said pivotal jaw to its closed position with respect to said fixed jaw, and for locking the pivotal jaw in said closed position. - View Dependent Claims (13, 14, 15, 16, 17, 18)
