Abstract
The invention relates to a device for intramedullary nailing of the tibia which comprises the frame of a framework which consists of vertical supports (2) and longitudinal (3, 4) and transverse horizontal supports (5, 5′, 5″, 6, 6′) and a guide (21): which is slidably coupled to the longitudinal horizontal support (4) of the device. The guide (21) comprises a first finder (11) for adjusting the position of the traction needle (20) in the lateral direction, and a second finder (13) for adjusting the position of the traction needle (20) in the vertical direction and for passing the traction needle (20) through the tibia in the transverse direction of the tibia, and attachment arms (22, 24) attached to the frame, to which the ends of the traction needle (20) outside the tibia are attached.
Claims11
A device for intramedullary nailing of a tibia, the device comprising:
- a base;
- a frame including vertical supports attached to the base, longitudinal horizontal supports attached to the vertical supports, and transverse horizontal supports attached to the vertical supports;
- wherein the vertical supports include a first vertical support, a second vertical support, a third vertical support, and a fourth vertical support;
- wherein the longitudinal horizontal supports include a first longitudinal horizontal support and a second longitudinal horizontal support, wherein the first longitudinal horizontal support is attached to the first vertical support and the second vertical support, and wherein the second longitudinal horizontal support is attached to the third vertical support and the fourth vertical support;
- and
- wherein the transverse horizontal supports include a first transverse horizontal support and a second transverse horizontal support, wherein the first transverse horizontal support is attached to the first vertical support and the third vertical support, and wherein the second transverse horizontal support is attached to the second vertical support and the fourth vertical support;
- a traction needle configured to be passed through the tibia;
- a guide slidably coupled to one of the longitudinal horizontal supports, the guide including:
- a first finder for adjusting a position of the traction needle in a lateral direction with respect to a joint surface of an upper part of the tibia;
- and
- a second finder for adjusting the position of the traction needle in a vertical direction and for passing the traction needle through the tibia in a transverse direction of the tibia;
- and
- attachment arms configured to be attached to the frame and to an end of the traction needle when the end is passed through the tibia in the transverse direction by using the guide.
