Description of drawings
Fig. 1 is user mode figure of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1: this utility model comprises long bone 1, internal fixation plate 2, trip bolt 3 and fracture line 4.
As shown in Figure 1: described internal fixation plate 2 is wrapped in the fracture line 4 on the long bone 1, and the shape of the fracture line 4 of the shape of internal fixation plate 2 and long bone 1 matches.For the fracture line 4 that wraps long bone 1 preferably, internal fixation plate 2 is symmetrically distributed in fracture line 4 places of long bone 1, and the end of internal fixation plate 2 is connected to a fixed by trip bolt 3.Trip bolt 3 on the internal fixation plate 2 parallels distribution, and the spacing of adjacent trip bolt 3 is at least 1cm; The spacing of the lateral edges of internal fixation plate 2 and fracture line 4 is at least 1cm, guarantees effectively fixedly fracture line 4 places of long bone 1 of internal fixation plate 2, guarantees that long bone 1 can effectively engage.Internal fixation plate 2 adopts steel plate or titanium plate to make.
Because the shape of internal fixation plate 2 need match with the shape of corresponding fracture line 4 on the long bone 1, so internal fixation plate 2 need customize according to the shape of fracture line 4.During customization: after patient's long bone 1 fracture, carry out the CT(computed tomography of whole long bone 1 by clinical radiologist) or MRI(Magnetic Resonance Imaging) tomoscan, each faultage image is carried out the dedicated graphics image software handle, obtain the three-dimensional reconstruction figure after long bone resets.After the orthopedist obtains three-dimensional image, at concrete conditions such as the position of fracture line 4, length, types, design the screw hole that trip bolt 3 can be installed on the main body of clinical implementation, that meet mechanical function, as to meet concrete fracture state of an illness internal fixation plate 2 and internal fixation plate 2, and the concrete shape and the thickness in described internal fixation plate 2 corresponding districts with holes, and the band screw hole the internal fixation plate district identify each screwhole position and size.When internal fixation plate 2 designs are finished, the 3-D view of long bone 1 fracture actual size and designed internal fixation plate 2 concrete forms are sent to production firm.After production firm obtains clinical data, produce the long bone 1 fracture site model that comprises the position of all soon performing the operation immediately, produce with the orthopedist and design identical internal fixation plate 2, after the aseptic process, send to clinical hospital fast.
