Detailed description of the invention
Main technical schemes of the present invention is: form blade plate by the substrate that utilizes thickness different and feature board compound, so, the substrate of thinner thickness easily deforms, and be located thereon thicker feature board and can be out of shape along with the distortion of substrate, macromolecular material blade plate so can be made can to carry out accurately moulding to ensure reset effect along the shape of bone.
By means of only embodiment and relevant drawings, technical scheme of the present invention is further elaborated below.
Fig. 2 a-2b is respectively the front and back schematic diagram of the macromolecular material blade plate that the present embodiment provides.As shown in Figure 2 a, macromolecule blade plate 1 comprises the feature board 12 of substrate 11 and composite joint with it, and wherein, the thickness of substrate 11 is less than the thickness of feature board 12, and substrate 11 and feature board 12 are made by macromolecular material.As shown in Figure 2 a, feature board 12 comprises multiple functional device 122, and above-mentioned multiple functional device 122 is evenly distributed on the front 111 of aforesaid substrate 11, and is also formed with gap 121 between adjacent functional device 122.And in the present embodiment, substrate 11 is composited by netted reinforcing rib and other macromolecular material, wherein, above-mentioned netted reinforcing rib is formed by the fibrage of high strength, like this when substrate 11 deforms at External Force Acting time, ensures that its intensity can not change.
Obviously, adopt above-mentioned setting, because the thickness of substrate 11 is less, then it easily deforms within the specific limits, therefore when bending distortion occurs substrate 11, can drive and be located thereon thicker feature board 12 and occur bending and deformation together, so, macromolecular material blade plate 1 can be made can be bent into difformity by concrete needs in different directions, and namely it can carry out accurately moulding along the shape of skeleton.
Fig. 2 c is cross section signal (for individual feature block) of the present embodiment blade plate.As shown in Figure 2 c, in the present embodiment, the thickness of feature board 12 is several times of substrate 11 thickness, and in Clinical practice, in order to make blade plate 1 and skeleton be consolidated, screw is often used to connect, therefore as shown in Figure 2 c, blade plate 1 also comprises the screw hole 14 running through substrate 11 and feature board 12, and each screw hole 14 is all arranged in each functional device 122.Preferably, in the present embodiment, the diameter of screw hole 13 is consistent with the size of screw 13 joined together, and the thickness of functional device 122 is consistent with the head thickness of screw 13 joined together.So, because screw hole 14 entirety is also limited by macromolecular material, be then fixed Shi Yineng when it matches with screw 13 and ensure that blade plate 1 has certain rigidity.
In addition, the QI-blood circulation of skeleton is hindered in order to make this macromolecular material blade plate avoid the periosteum at the position that powerful extruding is wrapped up by blade plate as conventional metals blade plate, as shown in Figure 2 b, preferably, at the back side 112 of substrate 11, namely contrary with the front 111 being provided with feature board 12 back side 112, be provided with protruding rib 15, and in the present embodiment, the quantity of the rib 15 of above-mentioned projection is two, be separately positioned on region corresponding with each functional device 122 on the aforesaid substrate back side 112, and relatively place.But those of ordinary skill in the art should be understood that the quantity of above-mentioned rib and position can be arranged according to specific needs, be not limited to above-described embodiment and describe.So, owing to adopting protruding rib, the contact surface between blade plate and periosteum can be reduced when blade plate uses, thus be conducive to the QI-blood circulation of skeleton, accelerate the quickly-healing of skeleton.
In addition, this macromolecular material blade plate 1 can be prefabricated into different shapes from size to meet different actual demands according to real needs, as shown in figs 3 a-3 c, it can make yi word pattern blade plate, Y-shaped blade plate, racemosus blade plate etc. respectively, concrete shape and large I design according to real needs, are not limited to above-mentioned illustrated exemplary.In addition, as previously mentioned, because feature board 12 is made up of multiple equally distributed functional device 122, and be provided with gap 121 between adjacent functional device 122, therefore also this macromolecular material blade plate 1 can be made as the applicable justifying of a size, as rectangle or square etc., then in Clinical practice, carry out cutting according to concrete demand along above-mentioned gap 121.
Further, in the present embodiment, the macromolecular material forming aforesaid substrate 11 and feature board 12 is daiamid-6 fiber or methyl methacrylate or N-vinyl pyrrole protective embankment ketone copolymers; Those of ordinary skill in the art are known, and above-mentioned macromolecular material also may be selected to be above-mentioned cited material other material connatural with other.As previously mentioned, substrate 11 is composited by netted reinforcing rib and other macromolecular material, and wherein, netted reinforcing rib is formed by the fibrage of high strength, and obviously, in the present embodiment, netted reinforcing rib may be selected to be and formed by daiamid-6 fiber braiding.
Fig. 4 a is the schematic diagram after racemosus blade plate bending distortion; Fig. 4 b is then that blade plate is at osteoepiphyseal portion application schematic diagram.As shown in Figs. 4a and 4b known, when Clinical practice, first bending distortion can be carried out in blade plate 1 direction as required, then, then to conform on skeleton 16 and to utilize screw 13 to be fixed, significantly, now, macromolecular material blade plate can carry out moulding along with the shape of periosteum.
In sum, adopt the technical scheme of the application, macromolecular material blade plate can be made can to carry out according to the shape of bone at normal temperatures accurately moulding, guaranteeing resets in synthetism process can not be lost, improve the feasibility of macromolecular material blade plate in Clinical practice and convenience, and, also help the QI-blood circulation of skeleton, accelerate the quickly-healing of skeleton.
