Abstract
The invention relates to an internal fixation device for proximal humeral fractures. The internal fixation device comprises a rod body and a metacarpus body arranged at the end part of the rod body, wherein the rod body and the metacarpus body form an angle of 30 to 45 degrees, branches distributed at intervals are arranged at the front part of the metacarpus body, the front end of each branch is vertically or obliquely and upwardly provided with a fixing stab, relative to the surface of the metacarpus body, for puncturing into the fracture surface of a residual humeral head. The internal fixation device provided by the invention has a simple structure and is convenient to use, and the rod body can be embedded into the bone marrow cavity of the humerus firmly through fillets at periphery, and is fixed with a broken humeral head through the fixing stabs on the metacarpus body and a tail end locking bolt. Compared with the traditional external steel plate fixing manner, more fastness and reliability are achieved, and sclerotin is reserved.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of inner fixer for proximal humeral fracture.
Background technology
Humerus is positioned at upper arm, is upper arm bone again, and its near-end is hemispheric head of humerus, forms shoulder joint with the glenoid cavity of scapula.
When there is displacement fracture in the proximal part of humerus, the fracture portions adopting steel plate to fix proximal humerus under normal circumstances makes it recover anatomical structure, because outer steel plate is eccentric fixing often, fix compared with central authorities, this just exists on mechanics fixes inapt factor, and when fracture cracked more serious, fixedly seem definite not.And for part because fracturing the serious patient needing to carry out Humeral Head Replacement that pulverizes, patient is more prone to accept to the internal fixation operation retaining self sclerotin, more meet physiological requirements.
Summary of the invention
Based on this, for above-mentioned technical problem, provide a kind of more perfect special inner fixer, for the treatment of part proximal humerus syntripsis.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of inner fixer for proximal humeral fracture, comprise the body of rod and be located at the palm body of described rod end, the described body of rod and described palm body are 30 °-45° angle, the front portion of described palm body has multiple bifurcated spaced apart, and the front end of each bifurcated all vertically or is obliquely provided with the fixing thorn for puncturing on residual fracture of the humeral head face relative to the surface of described palm body.
The surrounding of the described body of rod is provided with axially extended stupefied bar.
Described palm body is provided with multiple screw hole.
The side of described palm body is provided with for hanging sutural through hole.
Structure of the present invention is simple, easy to use, the body of rod by the stupefied bar of surrounding can be firm be embedded in the medullary cavity of humerus, and fixed by the fixing thorn on palm body and tail end lock screw and broken head of humerus, compared with traditional outer Interal fixation mode, more solid and reliable, retain sclerotin.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of palm body of the present invention;
Fig. 3 is the A-A sectional view of Fig. 1;
Fig. 4 is the structural representation of humerus.
Detailed description of the invention
As Figure 1-Figure 4, a kind of inner fixer for proximal humeral fracture, comprises the body of rod 110 and palm body 120.
The body of rod 110 is for inserting in the medullary cavity of humerus 2.
The surrounding of the body of rod 110 is provided with axially extended stupefied bar 111, and stupefied bar 111 can contact with the inwall of medullary cavity just mutually, and make in the medullary cavity being embedded in humerus 2 that the body of rod 110 can be firm, the body of rod 110 arbitrarily can not rotate in medullary cavity.
Palm body 120 is overall general in fan-shaped, it is located at the end of the body of rod 110, the front portion of this palm body 120 has multiple bifurcated 121 spaced apart, the front end of each bifurcated 121 all vertically or is obliquely provided with for the fixing thorn 122 on the broken head of humerus 21 of humerus 2 that punctures relative to the surface of palm body 120, by fixing thorn 122, the broken head of humerus 21 of humerus 2 is fixed on palm body 120, compare traditional outer Interal fixation mode, more firmly.
In addition, have and can fill broken bone and the gap supplying bone growth between bifurcated 121 spaced apart, this gap is by after human bone head growth, filling completely, can be coated on outside palm body 120, form an entirety, more firmly, and provide enough bone from growing space, knitting is faster.
Wherein, palm body 120 can be selected with the angle of the body of rod 110 within 30 °-45 °, adapts to wide.
Be understandable that, palm body 120 is provided with multiple screw hole 123 running through its positive and negative, and screw hole is provided with screw thread, can carry out angled locking with lock screw tail end, lock screw is fixed through this screw hole 123 and broken head of humerus 21, further enhances stability of the present invention and fastness.
Be understandable that, the side of palm body 120 is provided with for hanging sutural through hole 124, to sew up sclerotin.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
Claims (3)
1. the inner fixer for proximal humeral fracture, comprise the body of rod and be located at the palm body of described rod end, the described body of rod and described palm body are 30 °-45° angle, the front portion of described palm body has multiple bifurcated spaced apart, and the front end of each bifurcated all vertically or is obliquely provided with the fixing thorn for puncturing on residual fracture of the humeral head face relative to the surface of described palm body; It is characterized in that, the surrounding of the described body of rod is provided with axially extended stupefied bar.
