Problems solved by technology

In this case, using the above-mentioned pressure rod for downward positioning can only position the deformed intramedullary nail longitudinally, and it is easy to cause inaccurate pressure, or even the pressure rod slips relative to the intramedullary nail. In the end, the doctor can only choose to do it by hand. Operation

Embodiment Construction

[0026] Now in conjunction with the present invention figure 1 , 2 , clearly and detailedly state the implementation of the technical solutions of the present invention.

[0027] The invention discloses an intramedullary nail and its distal locking nail aiming system, which is formed by setting a tapered positioning hole at the distal end of the intramedullary nail, combining a positioning pressure rod whose head is a pointed cone, and supplemented by other aiming frames. Fix the frame to correct the longitudinal and lateral positions of the distal end, thereby improving the accuracy of the distal end of the intramedullary nail.

[0028] A kind of intramedullary nail 1, described intramedullary nail 1 comprises proximal end and distal end, is characterized in that: the proximal end of described intramedullary nail has proximal locking screw hole and a proximal waist hole; Said intramedullary nail The distal end has two distal locking nail holes, a taper hole and a distal wais...

Abstract

The invention relates to the field of orthopedic trauma especially fracture intramedullary fixation, provides a bone nail and a remote end nail locking sighting system thereof, and particularly relates to the stabler bone nail and the more accurate remote end nail locking sighting system during the surgical operation process. The bone nail comprises a near end and a remote end, and the near end ofthe bone nail comprises a near end nail locking hole and a near end kidney-shaped hole; the remote end of the bone nail comprises two remote end nail locking holes, a taper hole and a remote end kidney-shaped hole; an arc-shaped groove is formed in the surface of the bone nail. The system comprises the bone nail, a handle, connecting bolts, a near end sighting frame, a remote end connecting guiding rod, a remote end sighting frame, an E-shaped clamping block and a positioning pressing rod; one end of the handle is connected with the bone nail through a bolt, the other end of the handle is connected with the near end sighting frame through a first connecting bolt, the remote end connecting guiding rod is fixed with the near end sighting frame through a second connecting bolt, and the remote end sighting frame is fixed with the remote end connecting guiding rod through a third connecting bolt.

Description

technical field [0001] The invention relates to an intramedullary nail and its distal locking nail aiming system, which relates to the field of orthopedic trauma, mainly intramedullary fixation of fractures, and in particular to a more stable intramedullary nail and a more precise distal locking system during the operation. Nail sighting system. Background technique [0002] Intramedullary nailing is a commonly used internal fixation treatment option for fractures, and it is the preferred method for femoral and tibial shaft fractures. Based on the intramedullary nail structure, it belongs to biological fixation (relatively stable), and its stress distribution is relatively uniform, which has little effect on the fracture end, and its elasticity is beneficial to fracture healing. [0003] At present, in clinical practice, the distal fixation of the intramedullary nail is mainly assembled through the intramedullary nail, handle, connecting bolt, proximal aiming frame, distal ...
