Pencil-grip wire driver operated with distally located actuator
A wire driver for inserting a wire into bone. The wire driver includes a housing having proximal and distal ends, with a handpiece extending to the proximal end. The handpiece is connected to a gripping portion, which extends to the distal end. A channel extends through the gripping portion and is connected to a gripping mechanism. A drive mechanism within the handpiece is connected to the channel. The drive mechanism is configured to rotate the channel when actuated by a first actuator positioned on the handpiece (which can be on the distal end of the handpiece). A second actuator is connected to the gripping portion and the gripping mechanism. The second actuator is movable between a relaxed position and a compressed position. The user can operate both first and second actuators with the same handpiece grip. The gripping portion and second actuator are rotatable relative to the housing and first actuator.
1 . A wire driver, comprising:
a housing having a proximal end and a distal end, the housing comprising a handpiece extending from the proximal end to a gripping portion, wherein the gripping portion extends to the distal end;
a channel extending through the gripping portion;
a gripping mechanism connected to the channel;
a first actuator connected to the proximal end of the housing and extends from the proximal end of the housing to a position above a portion of the gripping mechanism; and
wherein the first actuator is movable between a relaxed position and a compressed position,
wherein the gripping portion extends along a first central longitudinal axis which extends through the gripping portion,
wherein the handpiece extends along a second central longitudinal axis, which is parallel to the first central longitudinal axis.
2 . The wire driver of claim 1 , wherein in the relaxed position, the gripping mechanism is closed.
3 . The wire driver of claim 1 , further comprising a drive mechanism positioned within the handpiece and connected to the channel, wherein the drive mechanism is configured to rotate the channel when actuated by a second actuator connected to the handpiece.
4 . The wire driver of claim 3 , wherein the second actuator is connected to the gripping portion and is movable between a relaxed position and a compressed position.
5 . The wire driver of claim 1 , further comprising a spring assembly within the gripping portion, the spring assembly connected to the gripping mechanism.
6 . The wire driver of claim 5 , wherein when the second actuator is in the compressed position, the spring assembly is compressed and the gripping mechanism is in an open position.
