Description
Affiliated technical field
This utility model relates to the orthopedic medical device technical field, particularly relates to a kind of intramedullary nail with lock localizer boring adjusting device.
Background technology
At present, intramedullary nail with lock internal fixation technology is widely used clinically, but the location in intra medullary nail far-end nail hole is the technical problem that is difficult to operation in the operation, fail to be solved well always, owing to the inaccurate phenomenon of boring failure that causes in location, nail hole happens occasionally, thereby the prolongation operating time increases patient's misery, influences surgical effect.Existing intramedullary nail with lock localizer boring adjusting device is to be welded with a U type frame on handle, and volume, weight are big, and the cost of manufacture height is regulated inconvenient operation by turning two screws.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of intramedullary nail with lock localizer boring adjusting device of simple in structure, easy to operate, accurate positioning is provided.
This utility model intramedullary nail with lock localizer boring adjusting device, comprise handle, the front end of handle is a square frame, be equipped with on the square frame and have externally threaded rotating shaft, knob is equipped with at the two ends of rotating shaft, vertical mobile adjustable column in the rotating shaft of being installed in is arranged in square frame, and lock nut is equipped with in the end of mobile adjustable column, and the lock(ing) bolt that is installed on the handle is arranged at the square frame rear.
Aforesaid intramedullary nail with lock localizer boring adjusting device, there is a tapped circular hole at its middle part of moving adjustable column, and this circular hole is passed in rotating shaft, and the two is assembled together.
This utility model utilization is installed in the angle of the mobile adjustable column adjustment locating rod in the rotating shaft, and is simple in structure light and handy, reduced the volume and weight of localizer, and processing cost is low; Very easy to use, the doctor grasps operational approach easily, and accurate positioning can reduce operating difficulty greatly, shortens operating time, alleviates patient's misery, improves the operation quality.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is that A among Fig. 1 is to view.
The specific embodiment
In the accompanying drawing illustrated embodiment, the utlity model has crooked handle 1, handle 1 lower end has the stationary pipes 2 that is used to install intramedullary pin.The front end of handle 1 is a square frame shape structure, is equipped with one on the square frame 8 and has externally threaded rotating shaft 4, and knob 5 is equipped with at the two ends of rotating shaft 4.Vertical mobile adjustable column 6 in rotating shaft of being installed in 4 is arranged in square frame 8, and there is a tapped circular hole at the middle part of mobile adjustable column 6, and this circular hole is passed in rotating shaft 4, and the two is assembled together.Lock nut 7 is equipped with in the end of mobile adjustable column 6, and the lock(ing) bolt 3 that is installed on the handle 1 is arranged at square frame 8 rears.During use, locating rod is contained on the mobile adjustable column 6, screw on lock nut 7 and lock(ing) bolt 3, turning knob 5, it is traversing that rotating shaft 4 promotes adjustable columns 6, and adjustable column 6 drives locating rods and finds bore position accurately, locks lock nut 7 then and lock(ing) bolt 3 gets final product.
