There are screw thread in worm screw 13, the part that speed changer is inserted into 11 end of draw bar, part and the snail of draw bar are passed through on case of transmission
Wheel axle center be provided with the matched screw thread of screw thread on draw bar, be consequently formed screw slider structure, i.e. the rotation of worm gear 15 drives
Draw bar 11 is moved along worm gear axis direction；The rocking handle 14 of speed changer side is fixedly connected with worm screw 13, is shaken from there through shake
The traction to suffering limb can be realized in handle 14.It is that doctor operates for convenience that rocking handle 14, which is designed in 12 side of speed changer,.
In addition to above-mentioned realization method, bevel gear, rack-and-pinion can be as commutation transmission agencies inside speed changer
One of realization method, the rack-and-pinion of bevel gear or mutual cooperation effect that two mutual cooperations act on, can be achieved commutation
Transmission agency.Preferably, both modes can also coordinate certain self-locking structure again.
Referring to Fig. 1 and Fig. 3, speed changer 12 is fixed on by speed changer bottom plate 5 on main panel 1, speed changer bottom plate 5 and interarea
It uses and is slidably connected between plate 1, and be fixedly connected by floor locking mechanism 16, be achieved in traction reduction module in main panel
The adjusting of 1 any position on graduated scale direction positions；Perpendicular to main panel 1 between speed changer lower casing 17 and speed changer bottom plate 5
1 normal direction of direction, that is, main panel on also using being slidably connected, and it is locked by bolt, to realize traction reduction module in interarea
The adjusting positioning of arbitrary height in 1 normal direction of plate；It is achieved in adaptation of the equipment to different suffering limb difference traction requirements.The bottom plate
Locking mechanism 16 is preferably spring insert-pull pin shown in Fig. 1-2, can also select clamping screw.
When using provided traction reduction equipment is invented, floor locking mechanism 16 is pulled open first, by speed changer bottom plate 5
1 least significant end of main panel is adjusted, then locks floor locking mechanism 16；Then, the folder between main panel 1 and external support board 2 is adjusted
Angle unclamps again support plate locking mechanism 18 to required angle, and pull support plate inner panel 3 is locked again after adjusting to required bearing height
Support plate locking mechanism 18；Later, which is placed in the underface of patient's suffering limb on operating bed, main panel 1
Parallel with the shank of suffering limb, suffering limb poples is placed on the concave arcuate structure 19 of equipment；Later, in suffering limb root bone appropriate location
On pierce Kirschner wire 7, mode covers upper position-limiting tube 20 at 7 both ends of Kirschner wire as shown in Figure 4, so that position-limiting tube 20 is clamped foot, unscrews
The company between draw bar 11 and ball-and-socket 10 in (but not turning off) ball strand connection structure is unscrewed by (but not turning off) floor locking mechanism 16
Connect so that traction reduction module position is adjustable, at this point, by between speed changer bottom plate 5 and main panel 1 in main panel graduated scale side
It is upward be slidably connected and speed changer lower casing 17 and speed changer bottom plate 5 between perpendicular to the direction of main panel 1 i.e. main panel
Being slidably connected in normal direction adjusts the position of traction reduction module, and the position-limiting tube 20 at 7 both ends of Kirschner wire is made to hook 8 end of traction bow
End locks two position-limiting tubes 20 with the bolt on traction bow 8, can thus limit sliding of the suffering limb along Kirschner wire axial direction.So
Locking floor locking mechanism 16 afterwards；Subsequently, rotation crank 14 draws suffering limb to required position, and lock ball twists to be led in connection structure
Draw the connection between bar 11 and ball-and-socket 10, realizes the fixation after suffering limb traction；Finally, by doctor manually complete traction reduction its
He operates.
The equipment application of the present invention, can in specific bone surgery (such as fracture of tibia reset, knee replacements)
Patient's lower limb are made to keep the pose of going down on one's knees of special angle, and suffering limb bearing height is adjustable.Connection structure is twisted by means of ball to make
