Abstract
The utility model relates to a main rod connecting apparatus for bone external fixing frames, in which a microspheric cardan joint mode is adopted to connect two main rods of the bone external fixing frame. One end of the main rod is processed to be spherical. The connecting apparatus is composed of a threaded pipe, two semi-spherical concave columns and two nuts with locks. The connecting apparatus forms a spherical cardan joint together with the spherical type head at one end of the main rod. The connecting apparatus belongs to the field of medical apparatus and instruments and is used for the reduction treatment of a fracture patient. In the process of clinic reduction external fixation, the novel bone external fixing frame is improved to be light in volume and convenient in installation, but the problem of fractured angulation or separation malformation can not be solved, and the requirements of the clinician can not be satisfied functionally. In the utility model, a bone external fixing frame which can not only pressurize but also adjust the direction of the main rod of the bone external fixing frame respectively is designed to solve the problem of fractured angulation or separation malformation.
Description
What this utility model patent related to is a kind of mobile jib connecting device of bone external fixer, is applicable to the bone external fixer that treatment bones of limbs fracture patient is used, and belongs to medical instruments field.
Known to going into regard to the present invention, the bones of limbs external fixation of fracture has a variety of with the metal external fixer, through updating, has obtained bigger perfect on profile, volume and function.Old-fashioned bone external fixer volume is big, use is heavy, be difficult for installation; New-type bone external fixer has dwindled volume, has used light and handy, installation easily.Even so, new-type bone external fixer still lacks pressurization and function is adjusted in split, in clinical reduction external fixation process, the angle often occurs fracturing into or separates deformity, when adjusting the bone external fixer, be difficult for again correcting, to such an extent as on its function, can not satisfy clinician's requirement.
The purpose of this utility model designs a kind of connecting device that can pressurize and can adjust bone external fixer mobile jib direction respectively exactly, fractures into the angle or separates deformity with solution.
The mobile jib connecting device of a kind of bone external fixer of this utility model is made up of a main thread pipe (not connecting), two recessed posts of dome-type, two nuts with lock.The nut top is porose, can pass mobile jib; Corresponding bone external fixer mobile jib is two, and every has an end is spherical type head.It is to realize connecting, pressurize, adjusting the mobile jib directive effect in the following manner: the mode in earlier two mobile jibs being occupied with spherical type head penetrates respectively in two nuts with lock; Again two recessed posts of dome-type are respectively charged in the main thread pipe both sides; Then two nuts with lock and main thread pipe are spun, in the process that screws, the direction of adjusting mobile jib continues to screw; At last, the pinning of locking belt locknut can be realized the effect that connects, pressurizes and adjust.Operation during operation also is a same steps as.
Below in conjunction with description of drawings embodiment.
As shown in drawings:
1, mobile jib (end is a spherical type head)
2, nut with lock
3, the recessed post of dome-type
4, main thread pipe
5, nut pinning
Mobile jib 1 is occupied interior mode with spherical type head to be penetrated in the nut 2 with lock; The recessed post 3 of dome-type is packed in the main thread pipe 4; Afterwards nut 2 with lock is spun with main thread pipe 4 one ends, offside is in like manner installed; After screwing nut with lock, the lock nut pinning is promptly finished the installation of connecting device.
