Abstract
本实用新型公开了一种桡骨带锁髓内钉，包括医用不锈钢制成的弧形的实心固定杆(1)，所述的实心固定杆(1)远端设置有与其一体成型制作的鸭嘴型的固定头(2)，近端设置有带有锁钉安装孔(4)的空心锁定体(3)。由于采用医用不锈钢制成的弧形的实心固定杆，植入后骨折对位效果好，同时采用鸭嘴型的固定头可以很好的将实心固定杆固定在髓内，防止了实心体固定杆在髓内移动而对人体造成的伤害。进一步的，该实心固定杆的形状为三棱柱形，由于三角形具有稳定性，因此可以对桡骨进行很好的固定。此外，该髓内钉创伤小，便于闭合复位植入，且结构简单、成本低廉、方便实用、适宜推广应用。
The utility model discloses a radius interlocking intramedullary nail, which comprises an arc-shaped solid fixing rod (1) made of medical stainless steel. The distal end of the solid fixing rod (1) is provided with a duckbill integrally formed with it. Type fixed head (2), the proximal end is provided with a hollow locking body (3) with a locking nail mounting hole (4). Due to the arc-shaped solid fixation rod made of medical stainless steel, the fracture alignment effect is good after implantation. Injury to the body caused by movement within the marrow. Further, the shape of the solid fixing rod is a triangular prism, and the radius can be well fixed due to the stability of the triangle. In addition, the intramedullary nail has less trauma, is convenient for closed reduction and implantation, has a simple structure, low cost, is convenient and practical, and is suitable for popularization and application.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of radius intramedullary nail with lock.
Background technology
Orthopaedics therapy fracture of radius at present, from far-end tuberosity entrance pedicle screw, controls rotation and the shearing of fracture end, but this kind of Therapeutic Method also exists not enough: 1. lack dissection radian, after implanting, fracture reduction is bad; 2. far-end locking is implanted difficulty; 3. need to have operative incision, wound is large, is unfavorable for closed reduction implantation.
Utility model content
This utility model, in order to solve the problems of the technologies described above, provides a kind of fracture reduction good, the radius intramedullary nail with lock that stability maintenance is high.
This utility model is to be achieved through the following technical solutions:
A kind of radius intramedullary nail with lock, comprises the solid fixed bar of the arc that medical stainless steel makes, and described solid fixed bar far-end is provided with the fixing head of the Duckbill type of making one-body molded with it, and near-end is provided with the hollow lock body with pinning installing hole.
Described solid fixed bar is shaped as triangular prism shaped, and triangular prism shaped circumscribed circle size is less than the inwall size of radius pulp cavity.
The radian of described solid fixed bar is mutually suitable with the radian of radius.
Described hollow lock body inner chamber is provided with female thread, is provided with and is with externally threaded shutoff nut in lock body inner chamber.
Compared with prior art, the utlity model has following useful technique effect:
This utility model radius intramedullary nail with lock, due to the solid fixed bar of the arc that adopts medical stainless steel to make, after implanting, fracture reduction is effective, adopt the fixing head of Duckbill type solid fixed bar can well be fixed in marrow simultaneously, prevented that solid fixed bar from moving in marrow and injury that human body is caused.
Further, being shaped as of this solid fixed bar is triangular prism shaped, because triangle has stability, therefore can well fix radius.
Further, in described hollow lock body inner chamber, threaded shutoff nut is installed, therefore can well prevents in the process of human body recovery, bone is put on flesh makes troubles to removing pinning.
In addition, this intramedullary pin wound is little, and be convenient to closed reduction and implant, and simple in structure, with low cost, convenient and practical, suitable applying.
Accompanying drawing explanation
The radius intramedullary nail with lock structural representation that Fig. 1 provides for this utility model.
Wherein: 1 is solid fixed bar; 2 is fixing head; 3 is hollow lock body; 4 is pinning installing hole.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in further detail:
A kind of radius intramedullary nail with lock, comprises the solid fixed bar 1 of the arc that medical stainless steel makes, and the described radian of solid fixed bar 1 and the radian of radius are mutually suitable; Described solid fixed bar 1 is shaped as triangular prism shaped, and triangular prism shaped circumscribed circle size is less than the inwall size of radius pulp cavity; Described solid fixed bar 1 far-end is provided with the fixing head 2 of the Duckbill type of making one-body molded with it, near-end is provided with the hollow lock body 3 with pinning installing hole 4, described hollow lock body 3 inner chambers are provided with female thread, in lock body inner chamber, be provided with and be with externally threaded interior hexagonal shutoff nut, can well prevent in the process of human body recovery, make troubles to after the fatty progress pinning installing hole 4 of initiation dismounting pinning.
Concrete, the tangent plane of this triangular prism shaped solid fixed bar 1 is triangle, and this leg-of-mutton circumradius is 3.6mm, and can obtain the leg-of-mutton length of side by computing formula is 6.2352mm.Wherein, solid fixed bar 1 is 0.5mm with the difference in height of the junction, inclined-plane of duckbilled fixing head 2.
Meanwhile, the tangent plane of this triangular prism shaped solid fixed bar 1 is triangle, and this leg-of-mutton circumradius is 3.2mm, and having computing formula can obtain the leg-of-mutton length of side is 5.5424mm.
When use, this intramedullary pin is put into radius pulp cavity, then pinning is inserted in pinning installing hole, radius is resetted fixing.
Meanwhile, described hollow lock body 3 and fixing head 2 also adopt medical stainless steel material to make, and its end has round and smooth edging, can prevent like this scratch that human body is produced.
It should be noted that, described hollow lock body 3 is similar or identical to the radian of Li Site tuberosity with the radian between solid fixed bar 1.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
