Description
One, technical field
This utility model relates to a kind of fractures additional device, more particularly, relates to a kind of inner fixer that is used for the ankle joint fracture treatment.
Two, background technology
Ankle joint is the maximum joint of human body heavy burden, and is unusual by ankle joint disorder, joint instability, articular surface out-of-flatness and mechanical behavior that different reasons cause, all will influence the heavy burden function of ankle joint, and fracture is wherein common reason.Along with the progress of society and the variation of mankind's activity mode, the ankle joint fracture that is caused by the high-energy damage increases year by year.It is generally acknowledged that ankle joint has a place above fracture or ligament injury, treatment promptly should undergo surgery, and the treatment that undergos surgery at first will reset fixing to ankle joint, this not only requires to reset accurately, the more important thing is and to carry out firm fixing to the ankle joint that resets, keeping the requirement that resets and satisfy early functional exercise, thereby reduce invalidly, promote functional rehabilitation.
In ankle joint fracture treatment, the medical personnel takes percutaneous to insert immobilising device usually, the ankle joint of fracture is resetted be fixed together.The ankle joint of fracture is resetted and closely is fixed together, the periosteum growth that can accelerate bone damage place widely with decrease the healing of folding place.The internal fixation device that is used for the ankle joint fracture treatment, prior art is existing multiple, but all has some defectives to some extent.Kirschner wire in the marrow, its deficiency be and can't pressurize at fracture site, especially sclerite more for a long time, its poor stability can not carry out early exercise, and it is more outstanding to keep the deficiencies such as valgus angle of outer ankle joint.The steel plate screw system of prior art, because its steel plate is 1/3 piped general steel plate, can not be well match with ankle joint and fibula or tibia, constant intensity is relatively poor, be difficult to satisfy the requirement of early exercise, when adopting DCP, L-DCP fixedly, lack, the anxiety of the cutaneous necrosis of causing is arranged because local soft tissue covers.And the steel plate screw system of prior art, because the screw mounting hole that matches with screw is positioned on the part main body front that steel plate and ankle joint match, with screw with steel plate and ankle joint fixedly the time, screw penetrates two-layer cortical bone and is easy to damage the ankle joint face, answer this when the processing ankle joint is far rolled over end, especially during comminuted fracture, make screw penetrate two-layer cortical bone and do not damage ankle pass face again, very difficult in operation, if make it only penetrate one deck cortical bone, firm fixing can't be reached again, therefore also just early functional exercise can't be really realized.Early functional exercise is very important, can not only promote the recovery of ankle joint function, the more important thing is the generation that can reduce or avoid complication such as ankle joint is stiff effectively.The therapeutic effect of the ankle joint fracture treatment inner fixer of prior art can't be satisfactory.
Three, summary of the invention
The purpose of this utility model provides a kind of inner fixer that is used for the treatment of ankle joint fracture of new structure form, the deficiency that exists with the ankle joint holder that overcomes prior art.The inner fixer that this utility model provides, can play the fixation that well resets to the ankle joint fracture position, can avoid hold-down screw to penetrate two-layer cortical bone again and injure articular surface, can implement early functional exercise, can reduce or avoid the generation of complication such as ankylosis effectively.To smashing ankle joint fracture, its advantage is particularly outstanding.
The inner fixer that is used for the treatment of ankle joint fracture that this utility model provides, the arcuate structure of its main body for matching with ankle joint and fibula or tibia, design has and is used for that holder and ankle joint and fibula or tibia are installed with the installing hole that securing member together matches on the main body, in the part both sides of the edge that main body and ankle joint match, at least one lateral edges design has and is no less than one earclip, and design has with the ankle portion that is used for holder and is installed with the installing hole that securing member together matches with ankle joint on earclip.The specific design mode of the earclip that design has an installing hole on the identical part both sides of the edge of retainer body and ankle joint, earclip both can design on the edge of both sides, also can design on the edge of one side, preferably designed on the edge of both sides.Its quantity can be that every lateral edges is provided with one, also can be that every lateral edges is provided with two or more, can also be that the edge of a side is provided with one, and the edge of opposite side is provided with two.The design of installing hole on earclip can be installing hole of an earclip design, can be that an earclip designs two or more installing holes, preferably installing hole of an earclip design.The whole set-up mode of earclip on retainer body and ankle joint match part should make the installing hole axis on it be positioned on the different cross section of ankle joint.The installing hole that is positioned on the earclip is preferably the threaded mounting hole that matches with screw fastener, and this ankle joint that helps fracturing resets fixing.
This utility model has also been taked some other measure.
Both sides design between the joint portion that the main body of holder and ankle joint and fibula or tibia match is jagged.Middle part design between the joint portion that the main body of holder and ankle joint and fibula or tibia match has the bar shaped aperture.These two measures can be adopted respectively, also can adopt in the lump, adopt the preferential previous measure of adopting separately.
With the ankle joint of this utility model treatment fracture, the doctor will appear fracture site earlier and be resetted, and it is identical that percutaneous makes retainer body and ankle joint and fibula or tibia then, is installed with screw then.
Of particular note, the installing hole that matches with securing member on the retainer body when holder specifically uses, might not all be used by each installing hole, but selects corresponding installing hole to use according to the concrete condition of ankle joint fracture.
The holder that is used for the ankle joint fracture treatment that this utility model discloses has following relatively more outstanding advantage with respect to the immobilising device of prior art:
1, because the arcuate structure of the inner fixer main part that this utility model discloses for matching with ankle joint and fibula or tibia, holder and ankle joint and fibula or tibia can be fixed together by the threaded mounting hole on trip bolt and the retainer body, after being resetted, the ankle joint of fracture can be well fixed, and fixing reliably firm, for carrying out early functional exercise, the patient provides reliable guarantee.
2, because retainer body and ankle joint and fibula or tibia mainly match and are fixed together by being positioned at screw hole on the part both sides of the edge earclip that holder and ankle joint match and screw, and the whole set-up mode of earclip on retainer body is, can make with its on the screw that matches of installing hole be fixed on the different cross section that ankle closes bone, therefore when holder being fixed together with ankle pass bone with screw, can not damage the ankle joint face even penetrate two-layer cortical bone yet, easy to operate, the steel plate screw system that has avoided prior art is when being fixed together steel plate and ankle joint with screw, screw penetrates two-layer cortical bone and damages the ankle pass easily, if make it only penetrate one deck cortical bone, fixing illusive again deficiency.With the inner fixer that this utility model discloses the ankle joint of fracture is treated, can carry out early functional exercise, promote functional rehabilitation, therapeutic effect is good, and can reduce or avoid the generation of complication such as ankylosis effectively.Especially to comminuted fracture, its advantage is more outstanding.
The ankle joint fracture inner fixer that this utility model discloses promptly can be used as internal malleolus articular fracture inner fixer, also can be used as outer ankle joint fracture inner fixer.
