Abstract
The utility model discloses a tibia osteotomy device based on ankle joint plane ultrasonic guidance localization. The tibia osteotomy device based on ankle joint plane ultrasonic guidance localization comprises an ankle holding device, a connecting rod and a tibia osteotomy module. An ultrasonic probe is installed on the ankle holding device. The ankle holding device is fixed to one ankle and connected with the tibia osteotomy module. The tibia osteotomy module is connected with the connecting rod and arranged at the top of the connecting rod. The ultrasonic probe is arranged so that the ankle joint face can be visually seen, the tibia osteotomy face is smoothly determined through devices connected in parallel without being influenced by tibia malformation, and the tibia osteotomy device has the advantages of being visual and high in accuracy. According to the tibia osteotomy device based on ankle joint plane ultrasonic guidance localization, clinic use is simple and convenient, images are objective, personal locating errors are avoided, and the problem that an existing tibia osteotomy device is inaccurate in localization in the process of use is well solved.
Description
Technical field
The invention belongs to technical field of medical instruments, relate in particular to a kind of Tibial osteotomy device based on ankle joint plane ultrasonic guiding location.
Background technology
In the operation of artificial complete knee joint surface replacement, important step is the osteotomy of tibia, target is to ensure that its Osteotomy is parallel with articular surface of ankle, to avoid the occurring inside and outside talipes varus of knee joint after prosthese security protection, this is also that the operation of knee joint surface replacement the most easily goes wrong and the place of complication.
Ensure that the correct osteotomy of tibia has a lot of methods, mainly contain two kinds of the interior location of marrow and marrow outside fixs, in marrow, location need to be inserted locating rod in tibia pulp cavity, have advantages of that accuracy is higher, but shortcoming is also a lot, as large in wound, hemorrhage many, there are the shortcomings such as tibia when deformity can't be used, use less at present, marrow outside fix apparatus is the Tibial osteotomy orientation tool of current main flow, tibia is not had to wound, while having tibia deformity, do not affect use, can require to do corresponding adjustment outward at shank according to the difference of articular prosthesis, its main disadvantage but degree of accuracy is not high, marrow outside fix instrument is mainly according to outer bar (connecting rod) acquisition parallel with tibia ridge of marrow, or by tibial tubercle and the 1st, between 2 three-bristle cudrania bones, line obtains, to obtain by range estimation or feel to a great extent, in the time knocking locking pin, easily cause in addition the displacement of Tibial osteotomy module, inevitably there is error, exceeding the error of 2 ° will cause and clinically turn over or valgus deformity in serious, and be difficult to make up.
Summary of the invention
The object of the present invention is to provide a kind of Tibial osteotomy device based on ankle joint plane ultrasonic guiding location, be intended to solve the existing tibia bone device of abscissusing and use the inaccurate problem in location existing.
The present invention is achieved in that a kind of Tibial osteotomy device based on ankle joint plane ultrasonic guiding location, should comprise by the Tibial osteotomy device based on ankle joint plane ultrasonic guiding location: embrace ankle device, connecting rod, Tibial osteotomy module;
Embrace ankle device ultrasonic probe is installed, embrace ankle device and be fixed on ankle, embrace ankle device and connect Tibial osteotomy module, Tibial osteotomy module is connected with connecting rod, is arranged on the top of connecting rod.
Further, Tibial osteotomy module is connected with connecting rod by bolt.
Further, embrace ankle device and connect Tibial osteotomy module by connecting rod.
Further, adopt armful ankle device of expanding and dwindling according to patient's demand.
Further, adopt and rise and decline connecting rod according to patient's demand.
Tibial osteotomy device based on ankle joint plane ultrasonic guiding location provided by the invention, by being set, ultrasonic probe sees intuitively articular surface of ankle, and determine smoothly Tibial osteotomy face by parallel connected device, be not subject to the impact of tibia deformity, wound is little, go out insufficiency of blood, there is intuitively the feature that degree of accuracy is high.The present invention is clinical easy to use, and image is objective, has avoided artificial position error, preferably resolve existing tibia abscissus bone device use exist range estimation locate inaccurate problem.
