Abstract
The utility model relates to an external fixation support for orthopedics. The utility model comprises wire needles used for fixing a skeleton and more than two fixing frames of the wire needles. The wire needles penetrate through the fixing frames to be inserted in a bone at both ends of a fracture site. The two fixing frames are movably connected with members which are mutually matched and are respectively provided with a bending sliding surface. The sliding track of the bending surface is matched with the shape of a joint of the fracture site. The utility model can be used for the treatment and the distortion rectification of a bone dry and an intra-articular fracture. The utility model is good for training muscles and joint functions early, promoting blood movement, and preventing complication. A kirschner wire or a screw used for reduction is dialed or cut to lead the bone fracture to be internally fixed in a limited mode. The interference for the union of fracture is decreased, articular activities are reserved, and the utility model is good for the union of fracture.
Description
This utility model relates to a kind of orthopaedics external fixation device, especially for the monolateral external frisket of intraarticular and surrounding fracture thereof.
The orthopaedics external fixer is one of orthopaedics medical apparatus and instruments commonly used clinically.Use fixed mount treatment fracture can reduce operation wound, have simple to operate, easy nursing, better function and the low advantage of medical expense, can alleviate patient's misery greatly simultaneously, thereby extensively be subjected to medical personnel and patient's welcome without external fixation.At present, the more monolateral external frisket of clinical practice all with treat single shaft fracture or orthopedic be main purpose, generally form by body frame, universal ball joint, draw point fixed frame and draw point etc., there is not the axle of crossing over the joint in the fixed rack structure, long bone shaft fracture can only be applicable to, and treatment of intra-articular fracture and orthopedic can not be used for.So can only adopt the treatment of internal fixation operation method mostly to the articular fracture patient in clinical, promptly adopt peeling operation to expose the joint and adopt interior support therapies, be unfavorable for union of fracture.
This utility model purpose is to overcome above-mentioned shortcoming of the prior art and a kind of orthopaedics external fixer is provided, and makes it to be advantageously used in intra-articular fracture treatment and orthopedic.
This utility model purpose is achieved by the following technical solution:
The orthopaedics external fixer comprises draw point and two above draw point fixed frames that fix bone is used in forming, draw point passes in the bone at fixed frame insertion fracture site two ends, flexibly connected by the parts with crooked slidingsurface that coincide mutually between two fixed frames, the sliding trace of this curved surface is complementary with the fracture articular morphology.
Above-mentioned orthopaedics external fixer is strained and fixed by elastic ribbon between said two fixed frames.
Above-mentioned orthopaedics external fixer is established length-adjustable body frame between two fixed frames, this body frame is the Telescopic handle structure, and pull bar length fixed mechanism is housed.
It is orthopedic that this utility model not only can be used for key fracture, and can be used for treatment of intra-articular fracture and orthopedic.Help early stage muscle and function of joint exercise, promote blood fortune, prevent complication, fracture changes external fixation into by internal fixation, change outer the support into by interior support, fracture can by sledge dial reset or open reduction with Kirschner wire or the limited internal fixation of screw, reduced operation wound, reduced the foreign body implantation, thereby reduced interference union of fracture.In addition, use this utility model can keep the activity in joint, so the bending, the rotation stress that produce can alleviate limb activity the time help union of fracture.
Accompanying drawing 1 is the front view of this utility model embodiment.
Accompanying drawing 2 is the vertical view of this utility model embodiment.
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:
This utility model comprises draw point 1 and two draw point fixed frames 2,3 that fix bone is used in forming, and fixed frame 2,3 places fracture joint one side, and fixed frame is provided with vertical 4 above pin holes, and 4 pieces of Threaded steel needles hammer in the bone as the strong point.2,3 of two fixed frames are flexibly connected by the parts with crooked slidingsurface 4,5 that coincide mutually, and the sliding trace of this curved surface articular morphology therewith is complementary.
For preventing of the active connection place disengagement of two fixed frames, will be strained and fixed between two fixed frames with elastic ribbon 6 from slidingsurface.Can be on the draw point of fixed frame 2 with an end fixed connection of elastic ribbon, the other end is connected on the draw point of fixed frame 3.
For realizing that the purpose of fracture site traction pressurization is established length-adjustable body frame 7 between draw point fixed frame 2,3, this body frame is the Telescopic handle structure, and pull bar length fixed mechanism 8 is housed.Be connected by the universal ball joint 10 that is provided with detent mechanism between fixed frame 2 and the body frame 7, so that can become angle, rotation, the convenient use between fixed frame 2,3 and body frame.Outside body frame, be provided with the expansion link 9 that two ends and body frame 7 are fastenedly connected, be convenient to regulate.
