Description
Technical field
This utility model relates to medical instruments field, the auxiliary resetting means of especially a kind of fracture of shaft of femur operation.
Background technology
On Orthopedic Clinical, often can run into the patient of fracture of shaft of femur, because of leg muscle tractive, make fracture end produce rotation displacement, angulation displacement, cripetura displacement and lateral displacement, in fracture of shaft of femur internal fixation operation process, need first reset to it, conventional reset method is assistant's hands grasping suffering limb far-end, continuous traction, with antagonism muscle strength, make fracture end reduction, but this kind of reset mode needs assistant's both hands to hold thigh far-end with the powerful contractility of antagonism leg muscle, very effort, be difficult to adhere to for a long time, one improve one's methods for: on condyle of femur, distracted position hammers into osseous pin, continuous traction is carried out at assistant's hands grasping osseous pin two ends, but this kind of method may deform and cause operation failure because of osseous pin under huge External Force Acting.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of fracture of shaft of femur operation auxiliary resetting means for above the deficiencies in the prior art.
This utility model solve that its technical problem adopts technical scheme be: the auxiliary resetting means of a kind of fracture of shaft of femur operation, comprise assembly one, assembly two and U-shaped pin, described assembly one is made up of vertical connecting rod, locating rod and left lever, described locating rod is fixedly connected with left lever by vertical connecting rod, be fixedly connected with registration arm in described locating rod inner end, in described registration arm, be provided with several locating holes, in described left lever, be axially arranged with the left osseous pin hole of running through; Described assembly two is made up of vertical connecting rod, gag lever post and right lever, described gag lever post is fixedly connected with right lever by vertical connecting rod, in described gag lever post, be provided with groove, described groove and registration arm are connected, be provided with two spacing holes at described gag lever post inner end place, described spacing hole matches with U-shaped pin, in described right lever, be axially arranged with the right bone round needle hole of running through, described right bone round needle hole is coaxially corresponding with left osseous pin hole, and described assembly one and assembly two are fixed and are connected through locating hole and spacing hole by U-shaped pin.
Above-mentioned shaft fracture operative reduction device, the inner end of described left lever and right lever is respectively hemispherical projections.
Above-mentioned shaft fracture operative reduction device, the diameter in left osseous pin hole and right bone round needle hole is as 3.5mm.
The utility model has the advantage of: 1, simple in structure, easy to operate, time saving and energy saving; 2, be convenient to grip and apply external force; 3, the problem of effectively avoiding osseous pin to deform under external force; 4,, by left lever and right lever are applied to different directions active force, can correct rotation displacement, angulation displacement, lateral displacement and cripetura displacement simultaneously.

Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in detail below.
As shown in Figure 1, the auxiliary resetting means of a kind of fracture of shaft of femur operation, comprise assembly one, assembly two and U-shaped pin 4, its material can be aluminum, rustless steel or other hard materials are made, as described in Figure 2, described assembly one is made up of vertical connecting rod 9, locating rod 1 and left lever 11, described locating rod 1 is fixedly connected with left lever 11 by vertical connecting rod 9, be fixedly connected with registration arm 2 in described locating rod 1 inner end, in described registration arm 2, be provided with several locating holes 3, in described left lever 11, be axially arranged with the left osseous pin hole 10 of running through, as shown in Figure 3, described assembly two is by vertical connecting rod 9, gag lever post 5 and right lever 8 form, described gag lever post 5 is fixedly connected with right lever 8 by vertical connecting rod 9, in described gag lever post 5, be provided with groove 6, described groove 6 is connected with registration arm 2, at described gag lever post, 5 inner end places are provided with two spacing holes 12, described spacing hole 12 matches with U-shaped pin 4, in described right lever 8, be axially arranged with the right bone round needle hole 7 of running through, described right bone round needle hole 7 is coaxial corresponding with left osseous pin hole 10, described assembly one and assembly two are fixed and are connected through locating hole 3 and spacing hole 12 by U-shaped pin 4, above-mentioned shaft fracture operative reduction device, the inner end of described left lever 11 and right lever 8 is respectively hemispherical projections 13, above-mentioned shaft fracture operative reduction device, the diameter in left osseous pin hole 10 and right bone round needle hole 7 is as 3.5mm.
Its operation principle is: first on condyle of femur, distracted position hammers into 3.5mm osseous pin, left lever 11 and right lever 8 are enclosed within outside osseous pin, its inner hemispherical projections 13 is close to skin as far as possible, registration arm 2 coordinates with the groove 6 in gag lever post 5, be connected and fixed by U-shaped pin 4, if fracture end far-end shifts forward, registration arm 2 is placed in thigh front side; Otherwise be placed in thigh rear side, so far, make assembly one and assembly two relative positions fixing, thereby can avoid the osseous pin that its inside is passed that deformation occurs under external force; While correcting simple cripetura displacement, the left lever 11 of assistant's hands grasping and right lever 8 continuous traction; While correcting rotation displacement, the left lever 11 of assistant's hands grasping and right lever 8, in traction, apply in transverse section clockwise or counter clockwise direction external force; While correcting left and right directions angulation displacement and lateral displacement, the left lever 11 of assistant's hands grasping and right lever 8, and apply different pull strengths according to angulation and direction of displacement, while correcting fore-and-aft direction angulation displacement and lateral displacement, two assistants grip left lever 11, locating rod 1, right lever 8, gag lever post 5 simultaneously, and apply different pull strengths according to angulation and direction of displacement, by connection handle, thigh is applied to compressing so that the reduction of the fracture.
