Abstract
The utility model discloses a multi-functional miniature stereoscopic directing instrument, comprising a fixed system, a coordinate system and a delivery system for the surgical instruments, which are independent with each other. The utility model is characterized in that the fixed system is composed of a frame fixed on a skull, and a sliding bar and a sliding plate which are arranged on the frame. The sliding plate and the sliding bar can respectively slide along the X direction and the Y direction. The utility model not only can apply to the X wire directing operation, but also can do directing operation under the CT scanning. The exposure factor of the utility model can remain constant, and the calculation accuracy is enhanced.
Description
This utility model belongs to operation or auxiliary facilities is used in diagnosis, more particularly, is the multifunctional small-size stereotactic apparatus of a kind of X of being used for line, CT scan.
Patent Office of the People's Republic of China has announced that on August 17th, 88 application number is 87216014, and name is called the stereo brain orienting instrument that directly is fixed on the skull, is made up of separate fixed system, coordinate system and operating theater instruments delivery system.Its coordinate system is on the top of a rosette, is fixed with the orthogonal sectorial coordinate dish in two sides by support, and being separately installed with on the sectorial coordinate dish of two sides can be along the parallel mobile movable disk of covering of the fan.Its operating theater instruments delivery system is to fixedly connected with pilot hole by the locating hole on the movable disk.Its weak point is that fixed system adopts claw and screw.In the time of fixedly,, the coordinate system and the operating theater instruments delivery system on its top directly is fixed on skull surface by claw and screw in the boring of the skull surface of human brain.Because the skull surface out-of-shape does not have constant coordinate system, when taking the photograph sheet, the position can not constant generation obvious errors.Its weak point also is function singleness, and range of operation is little, can only be used for the X line again, can not take into account CT scan.
The purpose of this utility model is to avoid the deficiencies in the prior art part, and is constant thereby the sheet position is taken the photograph in assurance by improving the fixed system of the middle-size and small-size stereotactic apparatus of prior art, improves precision.The purpose of this utility model also is to provide a kind of small-sized stereotactic apparatus that can be applicable to X line and CT simultaneously, makes its multifunction.
The purpose of this utility model is achieved through the following technical solutions.
This utility model is made up of separate fixed system, coordinate system and operating theater instruments delivery system.
Described coordinate system is on the top of a rosette, is fixed with the orthogonal sectorial coordinate dish in two sides by support, and being separately installed with on the sectorial coordinate dish of two sides can be along the parallel mobile movable disk of covering of the fan.Described operating theater instruments delivery system is fixedlyed connected with pilot hole by the locating hole on the movable disk.
The fixed system that is characterised in that of the present utility model.
Described fixed system is made up of framework, slide bar and slide plate.Slide plate is fixed on the bottom of rosette, and is placed on the slide bar, and slide bar is placed on the framework.Slide plate can be made directions X on slide bar parallel mobile, and slide bar then can be made Y direction parallel sliding on framework.Described framework is a polygon, respectively is embedded with four little plumbous points respectively on its four sides, front, rear, left and right plate.Described little plumbous point is during as X line directional operation, the basic point of positive bit slice and lateral projection, in order to just calculating, the amplification coefficient K of lateral projection, determine the target spot angle and the degree of depth, this lead point also can be used as conventional stereotaxy, asks Z numeric reference line.
Feature of the present utility model also is, indicates graduation mark on the left/right panel of described polygonal frame and the slide bar respectively, and is embedded with " N " shape bonding jumper on the framework left/right panel respectively.During CT scan, available CT dip stick is directly measured the Z coordinate figure on image, the coordinate figure in the coordinate of being made up of slide bar and framework according to position finder center zero point and target spot just can accurately draw the distance to target spot at position finder center zero point, and deflection angle all around.
The utlity model has following advantage.
1, this utility model is both applicable to X line directional operation, again can be at the descending directional operation of CT scan, thus for combining with CT, the compact directional instrument opens up a new way.
2, the fixed system of forming by slide plate, slide bar and framework owing to employing, and, make exposure factor easily keep constant with frame fixation, eliminated because the error of the non-constant generation of exposure factor.
3, this utility model is provided with little plumbous point in frame sides, and on computational methods, amplification coefficient adopts both sides amplification coefficient meansigma methods, and computational accuracy is improved greatly.
4, this utility model can carry out bilateral simultaneously, many target spots are damaged and biopsy, has enlarged the compact directional instrument scope of application.
5, this utility model is simple in structure, use is flexible, easy to carry, in operation process, patient can rise at any time and sit or walking, nurses easily producing untoward reaction in the art.
