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, relate in particular to a kind of inner fixer for proximal humeral fracture.
Background technology
Humerus is positioned at upper arm, is again upper arm bone, and its near-end is hemispheric head of humerus, with the glenoid cavity of scapula, forms shoulder joint.
When the displacement fracture occurs in the proximal part of humerus, the fracture portions that generally adopts steel plate to fix proximal humerus makes it recover anatomical structure, because outer steel plate is eccentric fixing often, fix compared with central authorities, just there is on mechanics the inapt factor of fixing in this, and, in the situation that fracture is cracked more serious, fixedly seem definite not.And need to carry out the patient of Humeral Head Replacement because of the serious pulverizing of fracturing for part, patient is more prone to accept to the internal fixation operation that keeps self sclerotin, more meets physiology's requirement.
Summary of the invention
Based on this,, for above-mentioned technical problem, provide a kind of more perfect special inner fixer, be used 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, the palm body that comprises the body of rod and be located at described rod end, the described body of rod and described palm body are 30 °-45° angle, the front portion of described palm body has a plurality of bifurcateds spaced apart, and the front end of each bifurcated is all with respect to the Surface Vertical of described palm body or be provided with obliquely be used to the fixedly thorn that punctures on residual fracture of the humeral head face.
The surrounding of the described body of rod is provided with axially extended stupefied.
Described palm body is provided with a plurality of screw holes.
The side of described palm body is provided be used to hanging sutural through hole.
The present invention is simple in structure, and is easy to use, in the medullary cavity that is embedded in humerus that by surrounding stupefied of the body of rod can be firm, and the fixedly thorn by the palm on body and tail end lock screw and broken head of humerus are fixed, compare with traditional outer steel plate fixed form, more solid and reliable, keep sclerotin.
Description of drawings
The present invention is elaborated below in conjunction with the drawings and specific embodiments:
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 cutaway view of Fig. 1;
Fig. 4 is the structural representation of humerus.
The specific embodiment
As Figure 1-Figure 4, a kind of inner fixer for proximal humeral fracture, comprise the body of rod 110 and palm body 120.
The body of rod 110 is used for inserting in the medullary cavity of humerus 2.
The surrounding of the body of rod 110 is provided with axially extended stupefied 111, and stupefied 111 can contact mutually with the inwall of medullary cavity just, makes in the medullary cavity that is embedded in humerus 2 that the body of rod 110 can be firm, and the body of rod 110 can arbitrarily not rotate in medullary cavity.
In addition, has the gap that can fill broken bone and confession bone growth between bifurcated 121 spaced apart, after this gap is expired by human bone head growth, filling, can be coated on outside palm body 120, form an integral body, more firm, 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 °, adapt to wide.
Be understandable that, palm body 120 is provided with a plurality of screw holes 123 that run through its positive and negative, and screw hole is provided with screw thread, can carry out angled locking with the lock screw tail end, it is fixing with broken head of humerus 21 that lock screw is passed this screw hole 123, further strengthened stability of the present invention and fastness.
Be understandable that, the side of palm body 120 is provided be used to hanging sutural through hole 124, in order to sew up sclerotin.
But, those of ordinary skill in the art will be appreciated that, above embodiment illustrates the present invention, and not be used as limitation of the invention, as long as in connotation scope of the present invention, to variation, the modification of the above embodiment, all will drop in claims scope of the present invention.
Claims (4)
1. inner fixer that is used for proximal humeral fracture, it is characterized in that, the palm body that comprises the body of rod and be located at described rod end, the described body of rod and described palm body are 30 °-45° angle, the front portion of described palm body has a plurality of bifurcateds spaced apart, and the front end of each bifurcated is all with respect to the Surface Vertical of described palm body or be provided with obliquely be used to the fixedly thorn that punctures on residual fracture of the humeral head face.
2. a kind of inner fixer for proximal humeral fracture according to claim 1, is characterized in that, the surrounding of the described body of rod is provided with axially extended stupefied.
