Abstract
The utility model provides a bridge-type bone fracture plate with a better fixation effect and belongs to the technical field of medical appliances, and the bridge-type bone fracture plate is used for providing more stable early fixation to long bone fracture. The technical scheme provided by the utility model is as follows: the bridge-type bone fracture plate consists of a fixing steel plate, far-end screws and near-end screws, wherein two sides of a fracture line are respectively provided with multiple near-end screw holes; the near-end screws made of an absorbable material are screwed in the near-end screw holes; the area of the near-end screw holes is greater than that of screw caps of the near-end screws; the near-end screw holes are filled with the absorbable material; the middle of a absorbable material filler is provided with bolt holes; and the absorbable material is magnesium alloy or a magnesium alloy material with a coating. The bridge-type bone fracture plate has the following beneficial effects that in the bone fracture plate, the near-end screws made from the absorbable material (the magnesium alloy or the magnesium alloy with the coating) or the near-end screw holes filled with the absorbable material (the magnesium alloy or the magnesium alloy with the coating) are arranged near the fracture line, and the absorbable material of the near-end screws or the near-end screw holes can be adsorbed within 1-4 months, can achieve an effect of strengthening the fixation stability in the early stage and can achieve an effect of the bridge-type bone fracture plate after being adsorbed in the later stage.
Description
Technical field
This utility model relates to a kind of bridge-type blade plate of treating fracture, belongs to the orthopedic medical device technical field.
Background technology
In treatment of fractures, blade plate is one of main internal fixation device of treatment limb long tubular bone.The shortcoming of fracture bone plate is: the intensity of fracture bone plate can not satisfy the needs of adult thighbone and fracture of shaft of tibia internal fixation, need peel off the periosteum that blade plate is put the zone during operation technique, influences local blood fortune; Occur stress concentration and stress shielding after fixing easily, influence the stress stimulation of normal fracture site,, can cause displacement fracture in case becoming flexible appears in screw in addition.The bridge-type blade plate improves to some extent on the basis of fracture bone plate; The common trait of bridge-type blade plate is with fixing two the main fracture ends of steel plate; Do not contact fractured area, fix, the external force that acts on the steel plate is changed into pure tension force property external force with the mode of external splint.Because use indirect resetting technique, steel plate does not directly contact with fracture end, reduced destruction, and competent space is provided for fracture end position bone grafting to fracture end blood fortune.During clinical practice, need 3-4 piece of screw that bridge-type blade plate two ends are fixedly secured on main sclerite, and equilibrium strength of fixation on these two sclerites.Cross over the fracture crushed zone with long bridge-type blade plate, as long as fix at the blade plate two ends, it bears bigger distortion external force.Because bending stress is distributed in the long blade plate sections, so the stress of unit are is relatively low, thereby has reduced the risk of blade plate solid failure.But in clinical, find; The bridge-type blade plate also has weak point; Mainly be that constant intensity is poor; When callus does not form especially in early days, the reason that produces this situation be since two ends only 6-8 piece of screw fix, early stage be prone to take place because the screw hold is not enough, the insecure internal fixation failure that causes of fracture fixation.In order to address this problem, be necessary to design a kind of new bridge-type blade plate, to reach than the better fixed effect of existing bridge-type blade plate.
The utility model content
This utility model technical problem to be solved provides a kind of effect of strengthening stability maintenance, the better bridge-type blade plate of fixed effect that can bring into play the effect of bridge-type blade plate late period after the absorption of can playing in early days.
The technical scheme that solves the problems of the technologies described above is:
The better bridge-type blade plate of a kind of fixed effect; It is made up of fixation steel plate, distal screw; Away from the two ends of fracture line 3-4 distal screw holes arranged respectively at fixation steel plate, distal screw and distal screw holes are complementary, and its improvements are; A plurality of proximal screws hole is arranged respectively in the fracture line both sides, be rotary with the proximal screw that absorbable material is made in the proximal screw hole.
The bridge-type blade plate of said fixing better effects if; The area in the proximal screw hole of said fracture line both sides is greater than the area of the screw cap of proximal screw; In the screw in proximal screw hole, be filled with the absorbable material implant, the through hole that the central authorities of absorbable material implant have the screw diameter with proximal screw to be complementary.
The bridge-type blade plate of said fixing better effects if, said proximal screw hole in the fracture line both sides are respectively 1-3.
The bridge-type blade plate of said fixing better effects if, said absorbable material are the magnesium alloy materials like magnesium alloy or coating.
The usefulness of this utility model is: blade plate has the proximal screw that the absorbable material of magnesium alloy or coating magnesium alloy makes or the proximal screw hole of filling near fracture line; The absorbable material implant in proximal screw or proximal screw hole absorbed at 1-4 month; The effect of strengthening stability maintenance can be played in early days, the effect of bridge-type blade plate can be brought into play after absorbing late period.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Fig. 2 is the another kind of structural representation of this utility model.
Labelling is following among the figure: bone 1, fracture line 2, fixation steel plate 3, distal screw 4, proximal screw hole 5, proximal screw 6, absorbable material implant 7.
The specific embodiment
This utility model is made up of fixation steel plate 3, distal screw 4, proximal screw hole 5, proximal screw 6.
Fig. 1 shows; After the reduction of the fracture; According to the settled principle of bridge-type blade plate, the fixation steel plate 3 of this utility model each is fixed with 3-4 piece of distal screw 4 away from the two ends of sclerite, increased a plurality of proximal screws hole 5 than bridge-type blade plate respectively in fracture line 2 both sides; Be rotary with the proximal screw 6 that absorbable material is made in the proximal screw hole 5, near the proximal screw 6 the fracture line 2 is that the absorbable materials such as magnesium alloy materials of magnesium alloy or coating are made.Behind the proximal screw 6 of bone fixation broken line 2 both sides, proximal screw 6 absorbed at 1-4 month.Proximal screw 6 can play the effect of strengthening stability maintenance in early days, can be converted into the effect of bridge-type blade plate after absorbing late period.Be respectively 1-3 in the proximal screw hole of fracture line 2 both sides.
Fig. 2 shows; Another improvements of this utility model are; The area in the proximal screw hole 5 of fracture line 2 both sides is greater than the area of the screw cap of proximal screw 6; In the screw in proximal screw hole 5, be filled with absorbable material implant 7, the through hole that the central authorities of absorbable material implant 7 have the screw diameter with proximal screw 6 to be complementary.Proximal screw hole 5 be shaped as oblong aperture or circular hole; The absorbable material implant 7 of filling in the hole is the magnesium alloy materials of magnesium alloy or coating; Absorbable material implant 7 absorbed at 1-4 month; The effect of strengthening stability maintenance can be played in early days, the effect of bridge-type blade plate can be converted into after absorbing late period.
The proximal screw 6 that in the proximal screw hole 5 of being filled by absorbable material, uses can also can be common orthopaedics trip bolt for the screw of same material.
