In the present embodiment, the head end of internal fixtion body 1, jackscrew 11, connecting rod 2 and operating grip 5 is that fine grinding sands flat face, strengthens connective stability by increasing frictional force.
In the present embodiment, being integral type structure with reference to accompanying drawing 3 internal fixtion body 1 head and afterbody, is universal structure with reference to accompanying drawing 4 internal fixtion body 1 head and afterbody, and namely afterbody is through head recess 101, and can slide.
Utilize operating process of the present invention as follows:
System, in conjunction with external fixation of fracture and Plate internal fixiation and the fixing principle of spinal column, is introduced the fixing of extremity fracture by the present invention.Design the principle in line with Wicresoft, rule of operation is as follows:
1, getting 1cm skin incision for row internal fixtion body 1 bearing, through being separated to periosteum, inserting soft tissue protection sleeve, using the bit bore than thick half millimeter of internal fixtion body 1 far-end, then use the tapping matched with internal fixtion body 1 screw thread to expand bone tunnel.Measure the length of required internal fixtion body 1, internal fixtion body 1 to the internal fixtion body 1 that then percutaneous is screwed into applicable length and diameter penetrates contralateral cortex and passes about 2 millimeters.
2, to use within the scope of the head end 2mm of internal fixtion body 1 be a Diameter Gradual Change structure, this structure tail end is identical with internal fixtion body 1 diameter, and be distally tapered to 1mm less of internal fixtion body 1 diameter, this class formation can facilitate being screwed into smoothly of internal fixtion body 1.
3, according to described in step 1 and 2, first 2 pieces of internal fixtion bodies 1 be of convenient length respectively are screwed into the main sclerite of the far and near end of fracture is as far as possible parallel.
4, the two ends of pruned be of convenient length 2 connecting rods and universal connectivity kit are combined, make 2 connecting rods and universal connectivity kit integral and make gimbal suspension be in relaxed state.
5, by tunnels between subcutaneous deep fascia and superficial fascia, the external member combined through time hypodermic tunnel inserting step 4 is also installed on internal fixtion body 1 afterbody.
6, jackscrew 11 is installed fixing 2 internal fixtion body 1 afterbodys farthest away from fracture end.
7, operating grip 5 is fixed on 2 internal fixtion body 1 afterbodys closest to fracture end, by adjustment operation handle 5, can 2 universal connectivity kit on indirect regulation connecting rod, make the reduction of the fracture.
8, perspective tightens universal connectivity kit, removal operation handle 5 after seeing the satisfaction that resets, skin suture after installation residue jackscrew 11.
If fracture is compound fracture in practice, then longer and thicker internal fixtion body 1 can be selected to fix according to exterior fixation bracket principle, if the unstable quantity that can increase internal fixtion body 1 of fracture.
The foregoing describe ultimate principle of the present invention and advantage.The present invention is not restricted to the described embodiments, and is not departing from the prerequisite of the scope of the invention, and those skilled in the art can do many changes and improvements as required.Scope should be defined by appending claims and equivalent thereof.
