Slide slot in groove sidewall, screw rod are provided at both ends with nut one, and nut one is set on the outside of slide slot.
2010.11.24CN 201642300 U of disclosed Chinese utility model patent operates for a kind of skeletal traction through tibial tubercle
Locator comprising telescoping tube, adjuster and positioning pipe, it is characterized in that：Telescoping tube is made of outer tube and the section of interior bar two, outside
Adjuster is equipped between pipe and interior bar, telescoping tube both ends are equipped with holder, and the end of holder is respectively equipped with positioning pipe and scoops out pipe, fixed
It is waveform that position, which manages and scoops out the inner termination of pipe,.It can be according to patient when use the case where, is set by adjusting between outer tube and interior bar
Some adjusters, the holder spacing that adjustment telescoping tube both ends are equipped with, the positioning pipe for being then respectively equipped with two holder ends and
It scoops out pipe, be fixed on the position that patient needs dozen bone traction steel needle, then bone traction steel needle is inserted into positioning pipe, then squeezes into.
Invention content
In order to reduce the irregular situation of nail quality of setting, the present invention discloses a kind of skeletal traction through tibial tubercle nail merging guiding
Device can quickly make distracted position of the traction nail below shin bone merging tibial tubercle.Guider of the present invention can be helped
Traction nail is placed to satisfied traction screw way when orthopedist being helped to set nail.
Its structural characterization of the technical solution that the present invention takes is：
A kind of skeletal traction through tibial tubercle nail merging guider, which is characterized in that including tibial tubercle pedestal 1, distal tibial base
Seat 2, connecting rod 3, the tibial tubercle pedestal 1, distal tibial pedestal 2 are individually fixed on tibial crest and by 3 structures of connecting rod
At line of force holder, the line of force holder is parallel with tibial crest.
The distal tibial pedestal 2 is fixing device, it includes ontology 23, the India rubber band in bending tool toughness
21, the hook 22 at ontology both ends, by the binding of India rubber band 21 by 2 bundled fixed of distal tibial pedestal on tibial crest.
The tibial tubercle pedestal 1 is to adjust and be oriented to executing agency, it includes visual level instrument 11, transverse holes 13, cross
To connecting rod 12, connecting rod 14,
The accurate position of traction nail is checked and approved when being used to set nail in the top that the visual level instrument 11 is installed on tibial tubercle pedestal 1
It sets；
The transverse holes 13 be tibial tubercle pedestal 1 cross through hole, the transverse link 12 by the transverse holes 13 from
It is perpendicular with line of force holder by sliding and keeping；Then by 131 fixed lateral of fixed screw in transverse holes 13 when needing fixed
Connecting rod 12 is in tibial tubercle pedestal 1 in lateral position；The outer end of transverse link 12 can be inserted into connecting rod 14, connecting rod
14 keep it is parallel with line of force holder, connecting rod 14 can be free to slide on transverse link 12, when needing by screw into
Row fixes it in the position of transverse link 12；
Nail positioning duct 141 is set in 14 end of the connecting rod with one, described to set nail positioning duct 141 and connecting rod
14 ontologies are vertical, and traction nail is squeezed into the nail positioning duct 141 of setting for being oriented to；
Slide each regulating member (i.e.：Connecting rod 14 can free to slide on transverse link 12 and transverse link
12 in the transverse holes 13 by freely sliding), reach desired position, and 11 droplet position of level meter when setting nail positioning duct 141
When center, all screws are tightened, so that two pedestals and connecting rod 3 is become, rigidity is whole, and traction nail is by setting nail positioning duct
141 with transverse link 12 parallel across below tibial tubercle, to obtain best traction nail longitudinally perpendicular with shin bone to final,
And then perfect screw way parallel with it in the horizontal direction.
Based on above technical scheme, traction nail has been placed to by guider of the present invention when orthopedist can be helped to set nail
Beautiful, satisfied traction screw way.Not only ensure that fine steel needle is vertical with the holding of the shin bone longitudinal axis in sagittal plane, and can guarantee traction
Needle is also vertical with tibial shaft holding on coronal-plane and cross section.

Specific implementation mode
Technical solution of the present invention is described further with attached drawing with reference to embodiments.
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3, Figure 4：
The tibial tubercle pedestal 1 being placed on tibial tubercle divides with the distal tibial pedestal 2 being bundled in below on shank
It is not fixed on tibial crest, and line of force holder is constituted by connecting rod 3.The line of force holder is longitudinal parallel with tibial crest.Leg 6 shows
Opinion Fig. 1.
Distal tibial pedestal 2 has an India rubber bundling belt 21, and the hook 22 on joint base 2 can be by distal tibial base
2 bundled fixeds of seat are on tibial crest.
There is a visual level instrument 11 on tibial tubercle pedestal 1, inclining for upper and lower directions occurs in traction nail when can prevent from setting nail
Tiltedly.
There are one and the perpendicular transverse link 12 of line of force holder, transverse link 12 to pass through pedestal 1 on tibial tubercle pedestal 1
On transverse holes 13 can be free to slide, then by the 131 fixed lateral connecting rod of fixed screw in transverse holes 13 when needing fixed
12.12 one end of transverse link can place hollow connecting rod 14, and nail positioning duct 141, hollow company are set in 14 end of connecting rod
Bar 14 can be free to slide on transverse link 12, can be also fixed by screw.
All screws are tightened when 11 droplet of level meter is located at center when setting nail positioning duct 141 arrival desired position,
Pedestal and connecting rod 3 is set to be integrally formed, traction nail is by setting nail positioning duct 141 with transverse link 12 parallel across tibial tubercle
Lower section, to accomplish that traction nail is longitudinally perpendicular with shin bone, and then perfect screw way parallel with it in the horizontal direction.
Compared with 204931819 U of utility model patent CN, 201642300 U in the prior art, product of the present invention is set
It is different to count principle；Utility model patent in the prior art can only ensure that fine steel needle keeps hanging down in sagittal plane with the shin bone longitudinal axis
Directly, it can not ensure that pull needle is also vertical with tibial shaft holding on coronal-plane and cross section.
