The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1～Fig. 6, this utility model embodiment operation positioning navigating device is based on following concentric circular positioning principle: because X-ray refractive index in different medium is 1, the propagation so the X line is in line in different medium, the X-ray bundle that is issued to image amplifier or film from X line emitter is conical, conical shaped beam can be regarded as by becoming big gradually, successive coaxial circles is formed, suppose on this taper shape 3 A on any three parallel coaxial circles planes, B and C, if these 3 image overlaps on X line projection sheet, then these 3 must be on the same straight line with light source O, and these 3 corresponding with the position of respectively justifying by oneself (identical with the angle of the round heart separately, distance is proportional), vice versa.Referring to Fig. 1.
Thus, summarize the point location principle of X line: A, B, C 3 points in the Different Plane that same point light source O sets out, as long as meet with next condition, then other 2 conditions are also set up:
1, A, B, C in the cone-shaped space that same X line source O sends on the parallel plane of living in relative position identical;
2, A, B, C overlap in projection image;
3, A, B, C and light source are in same straight line.
Any one spatial point residing parallel plane in conical shaped beam all has uniqueness, so the point location principle is based on the solid location that the plane shows to some degree, certainly if the locus of certain point that knows for sure, that must carry out the location of 2 diverse locations, comprehensive 2 localized results just can simulate its locus, thereby finish space orientation.
Implementation method:
Target spot in the D=body (district, down with), i.e. doctor's point that in operation, need in human body, find, the point that need orient of this utility model just is such as the foreign body that needs in the foreign body excising operation to find; The X-ray that target spot D is sent by C arm machine in D '=body develops and is presented at point on the C arm machine display screen; E=body surface entrance (district, down together), skin surface operates on a little in promptly performing the operation; Locating piece under the F=(district, down together); The last locating piece of G=(district, down together); F '=following locating piece is presented at the point on the C arm machine display screen in the X-ray development of being sent by C arm machine; G '=upward locating piece is presented at the point on the C arm machine display screen in the X-ray development of being sent by C arm machine.
This utility model embodiment comprises dial plate 1, following dial plate 2, the optical alignment guider 3 that has the infrared laser emitter, optical alignment guider remote controller 5 and degree of depth aid.Optical alignment guider remote controller 5 is used for controlling optical alignment guider 3 start-stops and lighting angle.
Using method is as follows:
1, adjusts C arm seat in the plane and put, make target spot D in the body be presented at optional position on the display screen of C arm machine;
2, in C arm machine X-ray emitter and D point intermediate space, place dial plate 1, make the grid lines 11 of dial plate 1 and on C arm machine display screen, developing of the last locating piece G that is positioned at grid lines 11; Dial plate 2 under placing on the human epidermal skin can develop the grid lines 21 of dial plate 2 and the following locating piece F that is positioned at grid lines 21 on C arm machine display screen;
3, as if E point fixed-site in the operation, when performing the operation such as brain section, the doctor is that the selection ear location is the E point, then carries out following steps: 1) move dial plate 2 down, locating piece F is overlapped with the E point; 2) adjust C arm machine angle, make and D ' some coincidence on C arm machine display screen at F ', locating piece F and the interior target spot D of body be point-blank at present for this; 3) move to go up dial plate 1, make on C arm machine display screen overlap with and at G ' at F ' at D ', locating piece G, time locating piece F, the interior target spot D of body are point-blank on this moment; 4) carry out step 5;
4, if E point position is fixing in the operation, promptly the doctor can select the E point in scope, then carries out following steps: 1) move upward dial plate 1, make on C arm machine display screen overlap with D ' at G ', the interior target spot D of locating piece G and body point-blank on this moment; 2) move dial plate 2 down, make and D ' some coincidence on C arm machine display screen at F ', on this moment locating piece G, time locating piece F, the interior target spot D of body point-blank, following locating piece F position is as the E point; 4) carry out step 5;
5, locating piece G and following locating piece F take off locating piece G and following locating piece F on the record behind the position on the grid lines separately, adjust generating laser, make laser pass the position at locating piece G of going up and following locating piece F place on grid lines separately respectively;
6, if target spot D as seen in the body,, just can see after operating on, carry out step 7 such as the foreign body that needs in the foreign body excising operation to find; If target spot D is invisible in the body, be not positioned on the surface of organ such as target spot D in the body, but be positioned on the solid space of organ inside, and the very difficult resolution of naked eyes, then carry out step 8;
7, utilize the collimation of laser, laser will inevitably point to target spot D in the body, and can undergo surgery to navigate by the laser point indication arrives target spot D in the body;
8, need to prepare at least 2 cover this utility model, as shown in Figure 6, mobile C arm machine repeats above step in different angles, two cover this utility model will make the laser that sends separately intersect behind the location, use light intersection Positioning Principle location, use degree of depth aid to test its degree of depth then apart from skin.
If D is tiny or find that D has the possibility of moving, can in operation process, repeatedly repeat above operation, fine setting C arm machine.
The simple deformation or the combination of every this utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
