Abstract
The utility model relates to a fixed special anatomical form area of upper arm bone major tubercle fracture claw steel sheet belongs to medical instrument technical field. It includes plate body and a plurality of claw, the claw sets up in the plate body top. The juncture of plate body and claw is arc, and is identical with the convex knuckle of upper arm bone major tubercle. The quantity of claw is two to the long and thin claw of three shape. Still be equipped with two pressurization holes of sliding on the plate body. The utility model overcomes in the past direct fix with screw major tubercle fracture lead to easily the fracture piece smash with the spongiosa position fix with screw easy defect such as not hard up in jail, simple structure is convenient, coincide with the upper arm bone shape, the practicality is strong.
Description
Technical field
This utility model relates to a kind of fixing fracture of greater tuberosity of the humerus special anatomical form band pawl steel plate, belongs to technical field of medical instruments.
Background technology
Humeral fracture often betides on collum chirurgicum humeri, humeral shaft, condyle of humerus, humeral intercondy, Humeral lateral condyle, condylus medialis humeri.Wherein, be many with former three especially, any age can be betided.Many caused by direct violence and indirect violence, as when weight clashes into, extrudes, hits and holds down, hands or ancon land, violence reaches each position through forearm or ancon.X-ray inspection can be clarified a diagnosis, and the type of prompting fracture.
Plaster fixing, polylith Boards wall after the treatment of in the past fracturing adopts artificial reduction more, external fixer fixes or the method for surgical menopause (Interal fixation), and fixing after the hold mode adopting suspender belt more, this mode makes that suffering limb is sagging, disturbance of blood circulation.Therefore some inventions are had to provide the steel plate of avulsion fracture around fixing joint, as a kind of hook plate (201120108070) of fixing joint surrounding fracture, provide a kind of hook plate, one of them end surface shape is briar tooth, periarticular ligament can be made not relax, ligament reconstructive can be played again, the effect of fixation, but at present on the market not for the special implement of greater tubercles of humerus position fracture, the hook plate of fixing joint surrounding fracture does not match with greater tubercles of humerus position, and directly fix fracture of greater tuberosity of the humerus by screw and easily cause sclerite to be pulverized, the screw at spongiosa position is fixed loosely and easily loosens.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of fixing fracture of greater tuberosity of the humerus special anatomical form band pawl steel plate.
According to the technical scheme that this utility model provides, a kind of fixing fracture of greater tuberosity of the humerus special anatomical form band pawl steel plate, comprises plate body and several pawls; Described pawl is arranged at plate body top.
The intersection of described plate body and pawl is circular arc, matches with trochiterian circular arc knuckle.The quantity of described pawl is two to three, and shape is elongated claw-like, the front portion of pawl more directly, sharper, be convenient to be fixed in proximal humerus.Described plate body is also provided with two pressurization holes of sliding, is convenient to fixing proximal humerus greater tubercle fracture of pressurizeing.
The beneficial effects of the utility model: this utility model overcomes to be fixed greater tubercle fracture without special anatomical plate and direct screw in the past and easily cause sclerite to be pulverized and the fixing loosely easy defect such as loosening of spongiosa position screw, structure is simple and convenient, match with proximal humerus greater tubercle position special shape, practical.

Description of reference numerals: 1, plate body; 2, pawl; 3, slip pressurization hole.
Detailed description of the invention
As shown in Figure 1-2: a kind of fixing fracture of greater tuberosity of the humerus special anatomical form band pawl steel plate, comprises plate body 1 and several pawls 2; Described pawl 2 is arranged at plate body 1 top.
The intersection of described plate body 1 and pawl 2 is circular arc, matches with trochiterian circular arc knuckle.The quantity of described pawl 2 is two to three, and shape is elongated claw-like, the front portion of pawl more directly, sharper, be convenient to be fixed in proximal humerus.Described plate body 1 is also provided with two pressurization holes 3 of sliding, is convenient to fixing proximal humerus greater tubercle fracture of pressurizeing.
This utility model plate body 1 and pawl 2 intersection are circular arc, match with trochiterian circular arc knuckle, to adapt to normal anatomical shape, the front of pawl 2 is two to three more elongated pawls, the front portion of pawl more directly, sharper, be convenient to catch on greater tubercle and thrust proximal humerus internal fixtion.
During use, be first reset to normal position with the greater tubercle that pawl 2 catches on avulsion displacement downwardly towards interior, and suitably thrust bone internal fixtion, then plate body slide pressurization hole 3 internal drilling, be screwed into screw and make pawl 2 pressurize in fixing greater tubercles of humerus further.Instant invention overcomes in the past directly screw fix greater tubercle fracture and easily cause sclerite to be pulverized and the fixing loosely easy defect such as loosening of spongiosa position screw.
