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 pelvis 1, internal fixation plate 2, trip bolt 3 and fracture line 4.
As shown in Figure 1: described internal fixation plate 2 fixedly fits in fracture line 4 places on the pelvis 1, and the shape of the fracture line 4 of the shape of internal fixation plate 2 and pelvis 1 matches, and the end edge of internal fixation plate 2 can be surrounded whole fracture line 4.For the ease of the installation of internal fixation plate 2, 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 distance of the lateral edges of internal fixation plate 2 and corresponding fracture line 4 also is at least 1cm, guarantees effectively fixedly fracture line 4 places of pelvis 1 of internal fixation plate 2, guarantees that pelvis 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 pelvis 1, so internal fixation plate 2 need customize according to the shape of fracture line 4.During customization: after patient's pelvis 1 fracture, carry out the CT(computed tomography of whole pelvis 1 by clinical radiologist) or MRI(Magnetic Resonance Imaging) tomoscan, each faultage image is carried out the dedicated graphics image software handle, the three-dimensional reconstruction figure behind the acquisition pelvis-repositioning.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 district with holes on the described internal fixation plate 2, and identify each screwhole position and size in the internal fixation plate district of band screw hole.When internal fixation plate 2 designs are finished, the 3-D view of pelvis 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 pelvis 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.
