    摘要: An apparatus for manipulating a surgical needle is disclosed, comprising a body portion, a first needle receiving jaw mounted for movement on a distal end of the body portion and having a first needle engaging member, a second needle receiving jaw mounted for movement on the distal end of the body portion and having a second needle engaging member, the second needle engaging member being operatively interconnected to the first needle engaging member for relative reciprocal movement therewith, wherein each of the first and second needle receiving jaws has a recess for receipt of a portion of a surgical needle therein. The first and second needle engaging members are mounted for alternate reciprocal movement into and out of locking engagement with the surgical needle. The apparatus also includes a wheel rotatably mounted within the body portion with a proximal end portion of each of the first and second needle engaging members connected to opposing sides of the wheel such that rotation of the wheel simultaneously retracts one of the needle engaging members and advances the other. Also disclosed is a method of manipulating a surgical needle inside a body cavity using a surgical instrument having a control mechanism, a first jaw and a second jaw, where at least one of the jaws is mounted for movement between a first position adjacent the other jaw and a second position spaced apart from the other jaw.

    摘要: A surgical instrument according to an embodiment of the present invention includes a housing portion and an endoscopic portion having a proximal end and a distal end, the endoscopic portion including a pair of coaxial members attached at the proximal end to the housing portion. The endoscopic portion also includes an inner rod member slidable within an outer tube member. The endoscopic portion terminates at the distal end in a pair of jaw members disposed in opposing relation and relatively pivotal about a common point between at least an open position and a closed position. A jaw control mechanism is associated with the housing portion, and includes at least one actuating member movably mounted in the housing portion. The actuation member has at least one gripping portion thereon such that an operator of the instrument can better manipulate the actuating member with a single hand. A linking member is pivotally connected to the actuating member and the inner rod member. A notch portion is disposed on the rod member such that when the actuating member is moved in relation to the housing portion in a first direction to a first position the engaging portion engages the notch, locking the jaws in a closed position. The surgical instrument also includes means for preventing the inner rod member from moving from the first position whereby coaxial reciprocating forces are created in the inner rod member when the locking means are moved to the first position.
