Description

Intramedullary nail

This utility model relates to a kind of marrow internal fixation nail that is used for fixing long bone shaft fracture.

The marrow internal fixation nail mainly contains single nail class at present, as Flos Mume broach and many nail classes, follows closely as EnderShi.The Flos Mume broach is simple to operate, but subject range is little, is only applicable in the long diaphysis epimere fracture, and fastness and anti-revolving property are relatively poor, easily takes place fixing not firmly or be driven into difficulty, the sticking of needle, influences union of fracture.Many nail class marrow internal fixation nails such as Ender nail are the garden cylindricality, and its poor flexibility is used and is driven into difficulty often, and the sclerotin splitting easily takes place, and complication is more.

The purpose of this utility model is to overcome the weak point in the background technology and provides a kind of fixing reliable, good springiness, and anti-rotatory is strong, the marrow internal fixation nail that no complication produces.

The purpose of this utility model is achieved in that this nail for oblate, nail body front end point, and afterbody is provided with the hole, whole nail system camber, nail body cross section is oblate.

This utility model is compared background technology and is had following advantage:

1, because this follows closely the flat point of front end, and tail end is provided with the hole, therefore use this nail, it is easy and convenient to be driven into taking-up, the sclerotin splitting can not occur;

2, the nail body is curved, and cross section is oblate, thereby good springiness, and anti-rotation performance is strong, uses this nail, and no complication produces;

3, fixation is reliable, shortens healing time, reduces the patient suffering;

4, be equipped with corresponding driver and use and be driven into convenient and strength-savingly, do not damage the nail body.

Description of drawings is as follows:

Fig. 1 is this utility model front view;

Fig. 2 is this utility model side view.

Among the figure: afterbody (1), nail body (2), front end (3), hole (4).

Embodiment describes this utility model in detail below in conjunction with (accompanying drawing): the long 320-420mm of nail body (2) is even arc.The afterbody (1) of nail is provided with hole (4), and hook passes when supplying to get nail, reaches to get pin conveniently, and firmly good, it is flat pointed that the front end of nail (3) is made, and the cross section of whole nail body is oblateness, and cross section major diameter of the present utility model is 3.8mm, and minor axis is 2.8mm.Needing cortical bone hole making drill, oblate nail driver, extractor when using this nail is used.

Claims (2)

1, a kind of marrow internal fixation nail, the front end point of nail, it is curved to it is characterized in that following closely body, and nail body cross section is oblate.

2, marrow internal fixation nail according to claim 1 is characterized in that the afterbody of following closely body is provided with the hole.
