Advantage of the present utility model and effect are special in the measurement of assessing coronalplane balance recovery extent in patients with scoliosis undergoing, assisted surgery doctor assesses objectively coronalplane recovery extent in skoliosis orthomorphia, can adjust in time the orthopedic degree of coronalplane, to improve curative effect and the success rate of skoliosis orthomorphia; Reduce radiological dose in art simultaneously, also reduce the generation of the problems such as both shoulders after operation in patients are not contour, trunk inclination simultaneously.
Other concrete advantages of this utility model and effect will go on to say below.
Brief description of the drawings
Fig. 1---this utility model structural principle schematic diagram.
In figure, each label represents that corresponding component names is as follows:
Vertical survey bar 1, left ilium staple handle 2, left ilium staple 3, union joint 4, horizontal survey groove 5, ILR staple handle 6, ILR staple 7, vertical survey extension rod 8.
Detailed description of the invention
As shown in Figure 1:
Vertical survey bar 1 is connected with horizontal survey groove 5 by union joint 4, and is 90 °, and vertical survey bar 1 is connected with vertical survey extension rod 8 by nut, can increase the length of vertical survey bar 1 to reach the length of whole spinal column; Left ilium staple handle 2 can to reach optimum position, then be fixed in horizontal survey groove 5 by upper end screw thread in horizontal survey groove 5 in horizontal slip, then left ilium staple 3 is tightened by left ilium staple 3 external screw threads by built-in screw thread; The right is also that so ILR staple handle 6 can to reach optimum position, then be fixed in horizontal survey groove 5 by upper end screw thread in horizontal survey groove 5 in horizontal slip, then by built-in screw thread, left ilium staple 7 is tightened; 7 points of left ilium staple handle 2 and left ilium staple 3, ILR staple handle 6 and left ilium staples stand on horizontal survey groove 5.
The explanation of this utility model application process:
After patients with scoliosis undergoing orthotic procedure finishes, patient ventricumbent position, mark bilateral posterior superior iliac spine peak, respectively by left ilium staple 3, ILR is fixed 7 and is fixed on bilateral posterior superior iliac spine peak place, then by left ilium staple handle 2, ILR staple handle 6 slides to reach optimum position on horizontal survey groove 5, be fixed in horizontal survey groove 5 by upper end screw thread, again left ilium staple 3 upper external screw threads are connected with left ilium staple handle 2 lower end female threads, ILR staple 7 upper external screw threads are connected with ILR staple handle 6 lower end female threads, horizontal survey groove 5 is fixed in the same level with bilateral posterior superior iliac spine line.Finally by union joint 4, vertical survey bar 1 and horizontal survey groove 5 are connected, if vertical survey bar 1 is not and patient's shoulder height level, the vertical survey extension rod 8 of screwing on again; When measurement, get the line of the mid point of neck 7 spinous process and bilateral crista iliaca peak, use protractor to measure the angle forming between itself and vertical survey bar 1.As the angle forming between the two exceedes 5 °, can think on current patient's coronalplane and have balance-loss state, need in art, adjust in time coronalplane form, thereby reach poised state, so not only can avoid in time the drawback of the coronalplane balance-loss states such as the trunk inclination just found while standing after operation in patients.The length of vertical survey bar 1 (adding if desired vertical survey extension rod 8) is enough measured spinal column entirety once simultaneously, in so both can prosthetics, C arm machine be had an X-rayed the deficiency being limited in scope, and also can reduce largely perspective number of times and reduced radiation dose.
