Abstract
The utility model is an adjustable orthopaedics boring guide device, which comprises two cross hole-slide blocks; two passing holes, which are vertical with each other and are not in the same plane are arranged in the cross hole-slide blocks; a transverse slide pole is positioned in the transverse passing hole; a front longitudinal arm and a rear longitudinal arm are respectively arranged on the vertical passing hole; a boring cover is arranged in the passing hole, which is in the upper of the front vertical arm and is parallel with the transverse slide pole. The upper of the rear vertical arm is provided with an arc bend, whose end part is provided with tow spiry coattail shapes. The utility model can be convenient to adjust the spacing and the length for the front vertical arm and the rear vertical arm so as to make the front end of the boring cover and the upper end of the rear vertical arm hard lock on the nail-in end and the nail-out end. The device can guarantee the precision of the nail-in and the nail-out, so the surgery time can be shortened; the device can lighten patient pain and enhance the surgery quality.
Description
Technical field
This utility model relates to the orthopedic medical device technical field, particularly relates to the drilling director that uses in a kind of bone surgery.
Background technology
Clinically at present, adopt screw or draw point to fix for nearly joint part fracture internal fixation more, often use Kirschner wire as guide needle in the operation, traditional boring method mostly adopts the range estimation aiming, direction and length all are difficult to grasp, the accuracy that is difficult to guarantee inserting needle and goes out pin causes easily and repeatedly repeats to squeeze into, or squeezes into the pair damage that intraarticular causes surrounding tissue or joint.The patent No. is that the utility model of ZL97214428.5 has provided a kind of orthopaedics boring finder, though have certain guide effect, it is slippage easily in use, and it is convenient to regulate underaction, has influenced the accuracy of its positioning and guiding.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of simple in structure, flexible and convenient operation, the adjustable accurately orthopaedics drilling director of positioning and guiding are provided.
The adjustable orthopaedics drilling director of this utility model includes two cross bore slide blocks, is processed with not orthogonal two through holes in same plane in the cross bore slide block, and two through holes communicate at the middle part of cross bore slide block.In the cross through hole of two cross bore slide blocks, horizontal sliding bar is installed, be separately installed with preceding vertically arm and the vertical arm in back in the vertical through holes of two cross bore slide blocks, preceding vertical arm is fixed on the cross bore slide block with horizontal sliding bar by lock-screw respectively with the vertical arm in back.By lock-screw drill bushing is installed in the through hole that the vertical arm of pro-upper end parallels with horizontal sliding bar, the back vertically has inside arc-shaped bend in the arm upper end, and its end is the swallow-tail form that has two pointed tooths.
Aforesaid adjustable orthopaedics drilling director, the front end of its drill bushing is a zigzag.
This utility model in use, can adjust the spacing and the length of forward and backward vertical arm easily, the front end that makes drill bushing vertically can be clamped on the inserting needle end securely and go out the pin end in the arm upper end with the back, and in use can slippage, inserting needle and the accuracy that goes out pin have been guaranteed, positioning and guiding is accurate, and is very easy to use, and the doctor grasps operational approach easily, can reduce operating difficulty greatly, shorten operating time, alleviate patient's misery, improve the operation quality.

Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
The accompanying drawing illustrated embodiment the utlity model has the cross bore slide block 2 of two cuboids, is processed with not orthogonal two through holes in same plane in each cross bore slide block 2, and two through holes communicate at the middle part of cross bore slide block 2.A horizontal sliding bar 1 is installed in the cross through hole of two cross bore slide blocks 2, and horizontal sliding bar 1 is orthogonal solid for cross sectional shape.The vertical vertical arm 4 in arm 3 and back before in the vertical through holes of two cross bore slide blocks 2, being separately installed with, preceding vertical arm 3 and back vertically in the arm 4 cross sectional shape of hypomere be rectangle, be fixed on the cross bore slide block 2 with horizontal sliding bar 1 by lock-screw 5 respectively.Before vertically the epimere of arm 3 be processed into the drill bushing mount pad 6 of cuboid, be installed with drill bushing 7 by lock-screw 8 on drill bushing mount pad 6 and the through hole that horizontal sliding bar 1 parallels, the front end of drill bushing 7 has zigzag teeth 9.The back vertically has inside arc-shaped bend in arm 4 upper ends, and its end is the swallow-tail form that has two pointed tooths 10.The vertical arm 3 of pro-vertically has identical scale 11 respectively in the same side of arm 4 with the back, so that inserting needle end and go out the pin end and align.
