Description

Bone-knitting steel plate

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a bone fracture steel plate.

Background

Bone-knitting steel plates (also including alloy plates or titanium plates and other materials) are commonly used instruments for orthopedic surgery. Existing bone plates generally comprise a plate body that is shaped to fit the bone and a plurality of through or threaded holes are provided in the body. However, the existing steel plate may have the following disadvantages in the use process:

firstly, the steel plate is completely attached to the bone, so that the bone cortex is pressed in a large area, which is unfavorable for the generation of blood vessels and affects healing. Secondly, in order to guarantee the cooperation intensity with spicule etc., the screw hole requires certain thickness, and then steel sheet overall thickness increases, and volume weight increases, is unfavorable for healing and brings inconvenience for the patient. In addition, since the fracture parts are different, the through holes may interfere with fracture parts of the fracture, and the fracture positions cannot be used for placing nails, so that the fixation is not facilitated.

Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings that are needed in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only embodiments of the present utility model, and that other drawings can be obtained according to these drawings without inventive effort for a person skilled in the art.

As shown in fig. 1-3, the present utility model is a bone plate for fixation in fracture surgery, particularly femur fracture surgery. The fracture part profiling device comprises a steel plate main body 1 which is profiled with a fracture part, wherein a plurality of reinforcing support columns 2 are arranged on the steel plate main body in a staggered way, first matching holes 3 are formed in the reinforcing support columns, and the first matching holes are matched with bone needles (or bolts and the like) and are through holes or threaded holes; the steel plate is also provided with an oblong adjusting hole 4, the adjusting hole 4 corresponds to a fracture part of the fracture, a buckle cover 5 is arranged on the adjusting hole, a second matching hole 6 is arranged on the buckle cover, and the second matching hole is also matched with a bone needle (or a bolt, etc.), and is a through hole or a threaded hole; the plurality of the buckles are identical in appearance and can be in plug-in fit with the adjusting holes, the positions of the second fit holes on different buckles are different, and different buckles are selected according to the fracture positions so as to ensure the distance between the position corresponding to the bone needle and the fracture position, and the distance is generally 1-1.5cm.

Preferably: the upper end (far away from the bone) of the reinforcing support column is leveled with the upper surface of the steel plate main body, and the lower end protrudes out of the lower surface of the steel plate main body. The upper part of the steel plate is arranged in a flat way with the steel plate main body, so that the steel plate has good fit with the skin and can not cause great damage to the skin; the lower part protrudes to be contacted with the bone, so that a channel can be formed on the surface of the bone, thereby being beneficial to the growth of blood vessels and the like and the supply of bone nutrition and the healing of wound surfaces.

Preferably: the first mating holes are obliquely arranged in the reinforcing support columns. The upper part faces the center of the steel plate, the lower part faces the outer side, and the outer splayed arrangement is formed, so that the arrangement can be effectively matched with the intramedullary nail, and interference with the intramedullary nail is avoided. The first matching holes at the front end (the left upper part of figure 1) are staggered in a zigzag manner; the middle part is arranged in an approximate single row, and the inclination angles of the middle part are staggered leftwards and rightwards.

Preferably: the buckle cover is in a shape of a Chinese character 'tu', is inversely inserted in the adjusting hole, the lower edge of the inner side of the adjusting hole is provided with a limiting block 7 matched with the buckle cover, and the upper part of the limiting block is matched with the shoulder of the Chinese character 'tu' of the buckle cover to ensure good positioning.

Preferably: a third matching hole 8 is formed in the edge of the steel plate main body, one end of the third matching hole is opened on the upper surface of the steel plate main body, and the other end of the third matching hole is opened on the side face of the steel plate. The third fitting holes are fitted with binding wires (binding bands), and when the binding wires are required to be fixed, the wires are wound outside the bone and pass through the corresponding two third fitting holes. Compared with the mode that the groove is formed in the edge of the steel plate main body and used for fixing the steel wire, the structure is better in fixing effect and avoids falling possibility.

Preferably: a plurality of convex teeth 9 are arranged at intervals on the edge of the lower surface of the steel plate main body, the heights of the convex teeth are the same as those of the reinforced support columns, namely, the lower ends are flat, and the effect of assisting in fixing the steel plate and improving the stability of the steel plate can be achieved.

When the structure is used, the reinforced support column at the lower part of the steel plate main body is contacted with bones, so that a channel is formed between the steel plate main body and the bones, thereby facilitating tissue growth and improving fracture healing; the matching holes are formed in the reinforced support columns, so that the length of the matching holes is increased, and the reliability of fixation is improved. Meanwhile, the length of the matching hole is irrelevant to the thickness of the steel plate main body, so that the thickness of the steel plate main body can be properly reduced under the condition of ensuring the overall strength, thereby reducing the weight of the steel plate. When the steel wire is required to be fixed outside, the steel wire can pass through the third matching hole, so that the possibility of falling off of the steel wire can be avoided.
