Abstract
The invention discloses a tibia cutting device based on ankle joint planar ultrasonic guidance positioning. The tibia cutting device based on ankle joint planar ultrasonic guidance positioning comprises an ankle surrounding device, a connecting rod and a tibia cutting module. An ultrasonic probe is installed on the ankle surrounding device, the ankle surrounding device is fixed to the ankle, the ankle surrounding device is connected with the tibia cutting module, and the tibia cutting module is connected with the connecting rod and arranged on the top of the connecting rod. According to the tibia cutting device, an ankle articular surface is seen in a visualized mode through the arranged ultrasonic probe, the cutting surface of the part, to be cut, of the tibia is determined successfully through devices which are connected in parallel without being affected by tibia malformation, and therefore the tibia cutting device has the advantages of visualization and high precision. The tibia cutting device based on ankle joint planar ultrasonic guidance positioning is easy and convenient to use, images are objective, personal positioning errors are avoided, and the problem that an existing tibia cutting device is inaccurate in positioning in 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 guarantee 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.
Guarantee 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 is tibia when deformity the shortcoming such as can't use, 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, but degree of accuracy is not high, it is its main disadvantage, marrow outside fix instrument is mainly according to the outer bar (connecting rod) of marrow and the parallel acquisition of tibia ridge, 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, when knocking locking pin, easily cause in addition the displacement of Tibial osteotomy module, inevitably there is error, surpassing 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 connecting rod is connected, and 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 resolves the range estimation that bone device use to exist of abscissusing of existing tibia and locates inaccurate problem.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Tibial osteotomy device based on ankle joint plane ultrasonic guiding location that provides of the embodiment of the present invention;
In figure: 1, Tibial osteotomy module; 2, connecting rod; 3, embrace ankle device.
