Description
The present invention is a kind of universal directional multifunctional three dimensional direction finder for brain, belong to the department of cerebral surgery medical apparatus and instruments, it comprises following several architectural feature: by the lug on the groove fit guidance system base ring on the circumferential foundation ring, make guidance system can do 360 degree rotations, activity in conjunction with guide post on the guidance system and guider, constitute universal guide function, guidance system can be used for CT scan by central angle, eccentric throw and location highly, also can be used for the X line and take the photograph sheet by X, Y, Z three-dimensional coordinate location.A positioning framework is provided with N font deckle board for the three-dimensional location of CT, and mountain font deckle board is for X line location, and holder has the double worm and gear structure, can regulate position finder to the standard position.
Disclose on to 233 pages a kind ofly with the localized position finder of CT the 230th page of " Chinese neurosurgery " periodical 1989 the 5th the 3rd phase of volume, its purpose is to design to supply the stereotactic position finder of CT brain.This position finder is made up of holder, locating rack and guider three parts, and is furnished with adapter, holder is a tee T frame, has screw to be used for fixing patient's skull on it, and locating rack is a regular hexahedron framework, in order to determine the target spot coordinate, guider adopts centre of sphere guiding method, borrows adjustable right angle support that moves about to connect a circular arc, and this circular arc can rotate along Z-direction, slidably brain operator folder is arranged on the circular arc, can do various brain operations on demand.This position finder weak point is to be used for the CT brain stereotactic, can not be used for X line brain stereotactic, and holder can not rotate arbitrarily, thereby the angle of the rotation of the circular arc on the guider is also very limited, cause the dead angle, location bigger, can not satisfy multiple operation needs.
A kind of position finder (Preliminary experience with Brown-Roberts-Wells(BRW) computerized tomography stereotaxic guidance system is disclosed " neurosurgery (J.Neurosurg.) " periodical the 59th volume August nineteen eighty-three number the 217th page on to 222 pages), its purpose is to design to supply the stereotactic position finder of CT brain.This instrument is made of circular positioning base, arc positioning and guiding bar, localizer, N font positioning framework and simulator.This position finder weak point is to make the CT brain stereotactic, can not make X line brain stereotactic, this position finder is with X, Y, Z three-dimensional coordinate location, and X, Y, Z three-dimensional coordinate structure are on simulator, must rely on simulator during the location, after the location, advance cranium point and just be fixed on certain a bit, the new cranium point that advances can not be selected once more, per nasal sphenoid sinus hypophysis orientation can't be realized.
The objective of the invention is to avoid above-mentioned weak point of the prior art and a kind of universal directional multifunctional three dimensional direction finder for brain is provided, guidance system can be done 360 degree rotations on the foundation ring, and the activity of guide post on the guidance system and guider, constitute universal guide function, guidance system can be used for CT scan by central angle, eccentric throw and highly locating, also can be used for the X line and take the photograph sheet by X, Y, Z three-dimensional coordinate location, positioning framework is provided with CT scan and the X line is taken the photograph two groups of location of sheet deckle board, make CT and two systems of X line brain stereotactic integrate, be a kind of have simple in structure, multi-functional, the stereo brain orienting instrument of easy to operate and accurate positioning.
Purpose of the present invention can reach by following measure: the foundation ring is the circle of a circumferential, have on its face along the groove of periphery, 4 shanks are arranged on the inner rim, guidance system is by the circumferential base ring, semicircle guide post, and the guider three that can move on guide post constitutes, positioning framework has 4 deckle boards, it is one group with 2 relative deckle boards respectively, wherein one group is the CT location deckle board that is carved with N font gap, another group is for being inlaid with the X line location deckle board of mountain font galvanized wire, and holder has the double worm and gear structure.
Purpose of the present invention can also reach by following measure, and the groove on the foundation ring is near the inner rim of foundation ring, and it is equidistant arrangements that 4 shanks are arranged on the inner rim of foundation ring.
Guidance system is by base ring, and guide post and guider three constitute, and the back side inner rim of base ring is a lug that can match with the groove on the foundation ring.Orthogonal X scale is equipped with at the position that the two ends of guide post link to each other with base ring, Y scale and Z scale.One operation pilot hole is arranged on the guider, and there is the screw of a fixing operation utensil front portion of operation pilot hole.There is a guiding support bar that connects with ball cover at the guider back side, and the other end of guiding support bar passes base ring upper cardan hole.
Positioning framework is a regular hexahedron, its four sides are the identical foursquare location deckle boards of size, on the deckle board of CT location N font gap is arranged, on the deckle board of X line location, the bottom line of mountain font galvanized wire is a baseline, the intermediate vertical line is a center line, the both sides vertical line is a side line, is the top board that has passage above the positioning framework, is to be fixed on the circumferential base below the positioning framework, the bottom surface inner rim of base is a circle lug, and positioning framework is by for example lucite manufacturing of transparent material.
The present invention has following advantage compared to existing technology:
1, since guidance system can press central angle, eccentric throw and highly locate with CT scan, also can use X, Y, Z three-dimensional coordinate location, a positioning framework is provided with N font deckle board for the three-dimensional location of CT, mountain font deckle board is for X DNA mitochondrial DNA location, realized that a position finder can make two kinds of localized multi-functional effects.
2, guide post semicircular in shape, himself can do to be parallel to moving of X-direction, also can do to constitute universal guide function any point puncture on guide post perpendicular to the rolling to each side of X-direction, all can accurately hit target spot, reach directed dead angle minimum, adopt central angle, eccentric throw and highly carry out the CT brain stereotactic, it is not subjected to position finder to install or place the influence of inclination, make that localization method is simple, the calculating of minimizing rectification error, fast and accurate for positioning.
3, include the CT location deckle board in N font gap and the X line location deckle board of mountain font galvanized wire on a positioning framework, both can use separately, do not disturb mutually, X line brain stereotactic employing mountain font galvanized wire is taken the photograph the baseline and the center line that show on the sheet at the X line and is determined target position, and press the ratio of side line projected length and side line physical length, and calculate amplification, simplified the computational methods that China fir field formula position finder adopts mark post, easy and simple to handle, and simplified complete machine structure greatly.
4, position finder integral body is disk structure, guidance system can be done 360 degree rotations, and this design makes in the present position finder orientation method and instrument use and all becomes simple, has realized universal orientation, both be applicable to the three-dimensional location of posterior cranial fossa, also be applicable to location such as per nasal sphenoid sinus hypophysis.
The drawing of accompanying drawing of the present invention is described as follows:
The foundation ring of Fig. 1 universal directional multifunctional three dimensional direction finder for brain,
