Abstract

The utility model relates to a bone transposing device which comprises a main column, a bone needle holder, a regulating nut, a fender bracket and a needle bar. The enforcement of bone transposing for the limbs of osteonecrosis of a big section and ulceration of a large area muscle caused by serious osteomyelitis, etc. can be conducted, and the inclemency way of amputating is replaced. The bone having osteomyelitis or a big section of osteonecrosis is removed, the bone transposing is conducted to the large area of decaying inflamed muscle, and a complete limb is generated. The bone transposing device has is economic as compared with the operative treatment, such as splitting, skin grafting, etc., and the successful rate is very high. The bone extension can be conducted by the bone transposing device, and the orientation of the bone axial cord can be accurately ensured.

Description

Bone carrying device for carrying out said

This utility model relates to a kind of orthopedic instrument.Especially a kind of bone carrying device for carrying out said.

Because Different types of etiopathogenises: fracture or bone injury; Fracture operation postoperative infection etc. makes the trouble limb catch osteomyelitis, causes bone does not connect, even big section bone rotted, near large tracts of land muscle ulceration necrosis it.Over the years this pertinacious disease is taked treatments such as drain antiinflammatory all can not effect a radical cure.In order to prevent that damage from spreading, take amputation to handle, both caused patient's economic loss, more make the patient become handicap to cause remaining years misery.

Theory of medicine and practice show that skeleton can take measures to prolong, and extending length is more and more longer.

People utilize this theory and practice that the trouble limb of big section osteonecrosis while large tracts of land muscular decay is taked big section amputation bad bone of osteomyelitis and the septic muscle of large tracts of land, then two ends are remained NIP bone section difference and artificially disconnect (forming four sections) again section and nearest section are fixed farthest, then with other two sections (refer to cut an empty part) in the middle of the axis of bone alignment and move--being called the bone carrying--that practice shows that every day, every limit can prolong (moving) a millimeter, so not only skeleton is long, muscle vascular also elongates simultaneously simultaneously, make two sections mobile bones be carried to the middle generation callus of colliding after a few days, muscle is also collided simultaneously, generates complete limbs.

It is a kind of simple in structure that the purpose of this utility model is to provide, and bone carrying device for carrying out said easy to adjust and that can form monolateral bilateral several patterns finishes above-mentioned bone carrying and bone prolongs task.

Task of the present utility model realizes as follows:

Bone carrying device for carrying out said, it comprises two full thread master pillars, wears eight cover spicule clampers thereon, adjusts nut and compositions such as fender bracket and acuductor.

The spicule clamper is by the spicule frame, and the spicule pressing plate is connected to form with hold-down bolt.The spicule frame has axially extending bore, is through on the main pillar.Every cover spicule clamper two ends all are rotary with the adjustment nut, and every cover spicule clamper all can press from both sides two spicules, when nut is adjusted in rotation, the spicule clamper are moved axially along main pillar.

Fender bracket is semi-circular segmental support, and two ends has semi-ring to collude, and colludes on main pillar and twisted by fixed screw solid, is used to protect the amputation section to change dressings and can not be touched wound by quilt.

For making eight spicules keep same plane to penetrate skeleton and accurately placing the ad hoc acuductor of having counted of eight cover spicule clamper this utility model, can make the doctor finish the parallel task of eight pins easily with acuductor.

Good effect of the present utility model is:

1. adopt the axis hole structure, simple in structure.

2. main pillar adopts the full thread type, and eight cover spicule clampers can conveniently be adjusted on total length.

3. adopt the fender bracket of bow type on the arbitrary position of main pillar, fix, form bow type frame, protect wound with the built on stilts quilt on limbs etc. that covers.

4. adopt bridge formula structure to change dressings conveniently.

5. adopt the nut rotation mode to make conveniently moving reliable, make the metering of prolongation simple and convenient with six sides counting.

6. the acuductor of this utility model design can alleviate doctor's burden greatly, how much need not possess the experience of threading a needle and can wear eight spicules into parallel and be positioned at same plane.

7. this utility model moves two main pillars in one side and can form monolateral bone Handling device.Only can conveniently carry out bone with quadruplet spicule clamper prolongs.

8. this utility model can be to big section osteonecrosis, and large tracts of land muscular decay limbs carry out the bone carrying and generate complete limbs, need not adopt complicated splitting to mix and stir skin-grafting, alleviate the patient suffering greatly, and success rate are high.

9. this utility model also can carry out bone and prolongs to replace splitting and mix and stir skin-grafting and wait operation.

Below in conjunction with accompanying drawing enforcement of the present utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the structural representation of spicule clamper of the present utility model

Fig. 3 is that protector of the present utility model combines sketch map with main pillar

Fig. 4 is that acuductor of the present utility model combines the sketch map that carries out guide pin with the spicule frame

Fig. 5 is the structural representation of second kind of embodiment of the present utility model

Fig. 6 is the structural representation of the third embodiment of the present utility model

Fig. 7 is the spicule frame double-pore structure sketch map among second kind of embodiment of the present utility model

As Fig. 1--shown in 4 bone carrying device for carrying out said.It is the main pillar 1 by two full threads, adjusts the spicule that nut 2, eight covers (by hold-down bolt 3, spicule pressing plate 4, spicule frame 5) are formed

Clamper, two protectors 6, hold-down nut 7 and acuductor 8 are formed, and finish its design function.

As Fig. 2 the structure of spicule clamper is shown, it is by spicule pressing plate 4, and spicule frame 5 is formed.After penetrating, spicule screws with hold-down bolt 3.Main pillar 1 penetrates in the axial through hole of spicule frame 5, and both sides screw on adjusts nut 2.

Shown in Figure 3 is protector 6 and main pillar 1 bonding state.When colluding to twist with hold-down nut 7 after being stuck on the main pillar 1, protector 6 following form segmental supports admittedly.

The structure of acuductor 8 in use, forces together acuductor 8 usefulness hold-down bolts 3 as shown in Figure 4 with spicule frame 5, when spicule can be guaranteed its parallel penetrating smoothly when the hole of acuductor 8 penetrates.When using this utility model, by therapeutic scheme main pillar 1 is put on the spicule clamper earlier and screw on and adjust nut 2, penetrate eight spicules, the spicule position sequences by therapeutic scheme and spicule frame 5 usefulness is adjusted nut 2 and screws, unscrew eight hold-down bolts 3 then, remove spicule.Carry out disinfection respectively then.

On operating-table, by shown in Figure 4, acuductor 8 usefulness hold-down bolts 3 are pressed on the spicule frame 5, put on spicule of distal-most end, wear spicule of most proximal end again, two main pillars 1 are fixed on two spicules of having put on eight fulcra punch blocks 5.Penetrate remaining six spicules respectively with method shown in Figure 4 respectively then.Screw all hold-down bolts 3 after threading a needle.Implement just can carry out the bone carrying after the operation.

Fig. 5-the 7th, several embodiments in addition of the present utility model.Main pillar 1 is moved together; Make spicule frame 5 into diplopore spicule frame 10, show as Fig. 7 just to have become embodiment of the present utility model two as shown in Figure 5, become monolateral bone carrying device for carrying out said.

Only carrying out the bone prolongation if desired can be as shown in Figure 6 only with quadruplet spicule clamper, and two main pillars 1 and corresponding adjustment nut 2 can be finished the purpose of bone prolongation.
