Description
Technical field
This utility model relates to medicine and biological technical field, particularly shaft fracture Indirect reduction device.
Background technology
Due to how the shaft fracture of long bone of limbs is damaged by high-energy, the therapeutic modality of its main flow is for fixing in fracture closed reduction intramedullary pin, and the closed reduction of fracture (do not expose fracture site, fracture is carried out to Indirect reduction) is the key for the treatment of, it is also the difficult point of operation technique.
Before the present utility model, still lack effective instrument clinically and assist the Indirect reduction of shaft fracture, doctor is the free-hand Indirect reduction of many employings in operation, its defect comprises: 1. cannot realize effective traction of fracture site when free-hand Indirect reduction, thereby be difficult to correct the cripetura of fracture, even by extension table, be also difficult to overcome non axial muscle tone to the interference resetting; 2. the fracture near-end broken ends of fractured bone and the far-end broken ends of fractured bone be cannot accurately control when free-hand Indirect reduction, front and back, interior outside and the rotation displacement of fracture are therefore difficult to correct; 3. the clinical experience that free-hand Indirect reduction need to be abundant, many doctors are often unsuccessful due to free-hand Indirect reduction, carry out direct reduction and have to cut Dermal exposure fracture end, run counter to the principle of " closed reduction ".
Summary of the invention
The purpose of this utility model is just to overcome above-mentioned defect, develops a kind of shaft fracture Indirect reduction device.
The technical solution of the utility model is:
Shaft fracture Indirect reduction device, its technical characteristics be to be rotatably connected on the threaded rod on the bone holding claw on bone holding forceps upper end of lower bone holding claw, far-end bone holding forceps are also, bone holding forceps casing pipe sleeve is connected on the threaded rod of bone holding forceps, far-end bone holding forceps casing pipe sleeve is connected on the threaded rod of far-end bone holding forceps, the two ends of extension rod are round bar, on the threaded rod of stage casing, rotation socket extends nut, sliding sleeve and cripetura nut successively, bar bar cramp head by telescopic joint bone holding forceps on the round bar of one end of extension rod, bar bar cramp head by telescopic joint far-end bone holding forceps on sliding sleeve.
The lower end of described lower bone holding claw is below bone holding claw.
On the threaded rod of described extension rod, the left and right two ends of sliding sleeve are respectively to extend nut, cripetura nut.
The two ends of described extension rod are smooth round bar.
The utlity model has following advantage and effect: 1. by near-end and far-end bone holding forceps, can under the prerequisite of not cutting fracture site skin, accurately control the position of the fracture near-end broken ends of fractured bone and the far-end broken ends of fractured bone, while having overcome free-hand Indirect reduction, cannot accurately control the defect of the fracture near-end broken ends of fractured bone and the far-end broken ends of fractured bone; 2. by the prolongation effect of extension rod, can make fracture end obtain effective axial traction, thereby correct the cripetura of fracture, while having overcome hand operation, cannot carry out the effectively defect of traction of fracture end; 3. the rotary oscillation on extension rod by sliding sleeve, can correct the rotation displacement of fracture, is difficult to correct the defect of fracture rotation displacement while having overcome hand operation; 4. bone holding forceps can slide in bone holding forceps sleeve pipe, and for correcting front and back or the interior lateral displacement of fracture, while having overcome hand operation, south doctor corrects the front and back of fracture or the defect of interior lateral displacement.
Advantage of the present utility model and effect are also: can carry out easily the Indirect reduction of shaft fracture, easy and simple to handle, volume is little, cost is low, maintenance and change convenient.

Detailed description of the invention
Invention technical thought of the present utility model is:
Control the para-position of the fracture near-end broken ends of fractured bone and the far-end broken ends of fractured bone by near-end and far-end bone holding forceps, utilize extension rod and sliding sleeve above to correct cripetura, the rotation displacement of fracture.
Illustrate below.
As shown in Figure 1:
In this utility model, bone holding forceps 1 and far-end bone holding forceps 2 have identical structure, and taking bone holding forceps 1 as example, the bone holding claw 11 on it is slidably connected on lower bone holding claw 12 by the threaded rod of upper end, when clockwise or while being rotated counterclockwise threaded rod, bone holding claw 11 can to bone holding claw 12 near or separate.Bone holding forceps sleeve pipe 7 and far-end bone holding forceps sleeve pipe 8 are enclosed within respectively the threaded rod outside of bone holding forceps 1 and far-end bone holding forceps 2 upper ends.The two ends of extension rod 3 are smooth round bar, stage casing is threaded rod structure, be connected with in turn above and extend nut 5, sliding sleeve 4 and cripetura nut 6, wherein extend nut 5 and cripetura nut 6 and can on extension rod 3, move left and right when rotated, sliding sleeve 4 can horizontally slip in the threaded rod structure in extension rod 3 stage casings.Bone holding forceps sleeve pipe 7 is connected in the smooth round bar part in extension rod 3 left sides by bar bar cramp head 9.Far-end bone holding forceps sleeve pipe 8 is connected on sliding sleeve 4 by distal rod bar cramp head 10.
The explanation of this utility model application process:
In the time that shaft fracture (here taking fracture of shaft of femur as example) is carried out to Indirect reduction, first bone holding forceps 1 are fixed on by the mini-incision of fracture site near-end on the backbone of fracture near-end, far-end bone holding forceps 2 are fixed on by the mini-incision of fracture site far-end on the backbone of fracture far-end, the threaded rod of rotation bone holding forceps 1 upper end, make the downward bone holding claw 12 of bone holding claw 11 near also promptly key, in like manner rotate the threaded rod of far-end bone holding forceps 2 upper ends, make the bone holding claw of far-end bone holding forceps 2 lower ends promptly key, as shown in Figure 2.
Bone holding forceps sleeve pipe 7 and far-end bone holding forceps sleeve pipe 8 are enclosed within respectively on the threaded rod external screw thread of bone holding forceps 1 and far-end bone holding forceps 2 upper ends, as shown in Figure 3.
By bar bar cramp head 9, bone holding forceps sleeve pipe 7 is fixed in the smooth round bar part in extension rod 3 left sides, by distal rod bar cramp head 10, far-end bone holding forceps sleeve pipe 8 is fixed on sliding sleeve 4.Rotation cripetura nut 6, make it away from sliding sleeve 4, again rotation extend nut 5, make its near and push sliding sleeve 4 and move to the right, thereby make fracture end obtain axial traction, correct the cripetura of fracture, the simultaneously rotation on extension rod 3 by sliding sleeve 4, can correct the rotation displacement of fracture, in the time that cripetura and rotation displacement all obtain satisfied correction, rotation cripetura nut 6 makes it near also fixing sliding sleeve 4, as shown in Figure 4.
Slip by bone holding forceps 1 in bone holding forceps sleeve pipe 7, front and back or the interior lateral displacement of scalable fracture near-end.Slip by far-end bone holding forceps 2 in far-end bone holding forceps sleeve pipe 8, front and back or the interior lateral displacement of scalable fracture far-end, as shown in Figure 5.
Take the photograph sheet by normotopia in art and side position x-ray and judge the situation of the reduction of the fracture, if it is dissatisfied to reset, repeat aforesaid operations until fracture end recovers good para-position and para-position, as shown in Figure 6.
