The utility model content
The technical problems to be solved in the utility model be at above-mentioned deficiency provide a kind of simple in structure, easy to use, make the fracture of rib healing back rib Ultimum Ti bone fracture device close with the bone original shape.
For solving the problems of the technologies described above, this rib Ultimum Ti bone fracture device, whole by the Ultimum Ti material, comprise gripper shoe, two avris of gripper shoe are symmetrically distributed with arm, and its construction features is: every avris is installed with the reinforcement arm near between two adjacent arms of gripper shoe length centrage.
Gripper shoe mainly works to support rib fracture place, prevents the distortion of rib fracture place axial bending, gripper shoe two avris are installed with the arm that rib can be held tightly on gripper shoe, but, at bone fracture device be installed the back initial stage, bone fracture device is not very firm, along with the carrying out of human body respiration, the expansion of thorax, rib fracture place has a radially reciprocating motion by a small margin, this radial motion is all offset by gripper shoe, so gripper shoe can be subjected to a by a small margin reciprocal radial force identical with respiratory frequency in rib fracture place, deforms easily.In order to strengthen the intensity of gripper shoe, make gripper shoe more firm in the axial direction, not yielding, be installed with the reinforcement arm at the every avris of gripper shoe near between two arms of gripper shoe planar central, like this, the axial bending that is caused by breathing is out of shape, will be at first support by strengthening arm, and this distortion be applied to substantially strengthen arm axially on, well-known, axially the steadiness specific diameter is much better than to steadiness, so, by breathe caused radially reciprocating force will all offset strengthen arm axially on, after the rib healing, the bone type situation of excessive deformation can not occur between inboard shape of bone fracture device and rib prototype.
As improvement,, be installed with the reinforcement arm between the adjacent arm of the every avris of gripper shoe in order to make bone fracture device installation initial stage hardness stronger.Like this, not only be installed with the reinforcement arm near between two arms of gripper shoe planar central at the every avris of gripper shoe, between other adjacent arms of the every avris of gripper shoe, also be connected with the reinforcement arm, whole bone fracture device be it seems the three-dimensional wire side of halfpipe that curls along the wire side center line just as wire side two avris from the outside, because be a network structure, no matter it is be laterally or vertically, all more firm on the structure than single gripper shoe; The more effective prevention axial bending of stereochemical structure can resile when having guaranteed the rib healing.
As further improvement, in order to prevent arm slippage when holding rib tightly, the arm inboard is installed with anti-skidding thorn.After bone fracture device was installed, because the cause of nickel-titanium shape memory alloy material characteristic, the shape of bone fracture device was replied original shape gradually, hardness also changes software strategy into software-hardware strategy, but after bone fracture device had just been installed, hardness was very soft, in the process of bone fracture device typing, arm slippage from the rib easily is unfavorable for that rib resiles; After the arm inboard is installed with anti-skidding thorn, will effectively address this problem, after bone fracture device is installed, no longer slippage from the rib of arm has been played the effectively fixedly effect of rib, after the union of fracture, bone shape is a kind of more satisfactory healing result between original shape and bone fracture device cavity shape.
In sum, this rib Ultimum Ti bone fracture device is simple in structure, easy to use, fracture of rib healing back is approaching with the bone original shape, resumes treatment effectively, is the desirable substitute products of present internally-fixed bone fracture device.
In conjunction with the accompanying drawings this utility model is described in further detail:
