Abstract
A surgical device having a pair of slidably interlocking spring biased upper and lower shaft members. A grasping handle is associated with one end of the interlocking shaft members for grasping the same and sliding the upper shaft member forwardly along the lower shaft member. A grasping jaw member is pivotally connected to the other end of the shaft members, the jaw members being in meshing engagement thereby effecting a double jaw opening and closing when the upper shaft member is actuated with respect to the lower shaft member.
Claims14
A surgical device comprising:
- a first upper rigid elongated shaft member keyed along a substantial portion of its length to a second lower rigid elongated shaft member for reciprocal movement therealong in parallel relation thereto;
- handle means at one end of said first and second shaft members for grasping said device;
- biasing means associated with said first and second shaft members for normally biasing said first shaft member in a direction laterally along said second shaft member;
- an upper jaw member;
- a lower jaw member;
- said upper jaw member being pivotally connected to said upper shaft member and said lower jaw member being pivotally connected to said lower shaft member, each of said jaw members having a plurality of spaced teeth thereon, the teeth of one of said jaw members facing the teeth of the other of said jaw members;
- and
- said jaw members being in meshing engagement whereby reciprocation of said upper shaft member in a direction sliding along said lower shaft member and toward said jaw members and parallel to said lower shaft member moves said upper jaw member in a counterclockwise direction whereby said lower jaw member, in meshing engagement with said upper jaw member, moves in a clockwise direction thereby moving the teeth of said jaw members together.
In the device of claim including ratchet means associated with said handle means for ratcheting said upper shaft member with respect to said lower shaft member when said upper shaft member is reciprocated along said lower shaft member.
A surgical device comprising:
- a first upper rigid elongated shaft member keyed along a substantial portion of its length to a second lower rigid elongated shaft member for reciprocal movement therealong in parallel relation thereto;
- handle means at one end of said first and second shaft members for grasping said device;
- biasing means associated with said first and second shaft members for normally biasing said first shaft member in a direction laterally along said second shaft member;
- an upper jaw member;
- a lower jaw member;
- said upper jaw member being pivotally connected to said upper shaft member and to an extension portion of said lower shaft member, and said lower jaw member being pivotally connected only to said lower shaft member, each of said jaw members having a plurality of spaced teeth thereon, the teeth of one of said jaw members facing the teeth of the other of said jaw members;
- and
- said jaw members being in meshing engagement whereby reciprocation of said first upper shaft member in a direction sliding along said lower shaft member and toward said jaw members and parallel thereto moves said upper jaw member in a counterclockwise direction whereby said lower jaw member, in meshing engagement with said upper jaw member, moves in a clockwise direction thereby moving the teeth of said jaw members together.
