Fig. 2 is the top view that a kind of skull disclosed in this utility model punctures the embodiment of auxiliary positioning cap.As it can be seen, in an alternate embodiment of the invention, described coordinate setting portion 12 is shaped as long and narrow rectangular sheet, and it is axial that its long limit is parallel to described main body 1；Described coordinate setting portion 12 uses can demonstrate have the material of the image being clearly distinguished to make with tissue in CT or NMR (Nuclear Magnetic Resonance)-imaging.
The present embodiment is determined by the material in coordinate setting portion 12 and further enhancing its function.When carrying out intracranial imaging, described coordinate setting portion can be to have the pattern being clearly distinguished to show in imaging results with tissue (including skeleton or soft tissue), so have only to according to the coordinate setting portion 12 corresponding to affected part in intracranial imaging, find the location line in described coordinate setting portion 12 further, find two location lines in the joint place of patient's scalp, i.e. can determine that and execute art position, further simplify operation, improve the degree of accuracy of operation technique.
Further combined with Fig. 2, with a reference example, above-described embodiment is illustrated.
In this reference example, the distance between depth localization portion 11 is 2 centimetres, and the distance between the plane of line place, location is also 2 centimetres.
(1) when for this positioning cap of patient worn, the lower limb of main body 1 is alignd with the timebase of scanning device (the initial plane that timebase starts scanning for identifying scanning device), by the coordinate setting portion of No. 1 coordinate setting line upper end just to patient's skull median plane, and this location line is alignd with scanning sagittal line (centrage that scanning sagittal line is scanning device imaging).
(2) if when carrying out intracranial image scanning, determine that affected part is positioned at the plane in 6 centimetres of face, main body 1 lower limb place of distance, in described main body 1, then find corresponding depth localization portion, i.e. counting from first depth localization portion 11 of main body 1 lower limb, the 4th depth localization portion 11.
(3) if the intracranial scanogram of affected part (assumes now location line invisible as shown in Figure 2, but coordinate setting portion can make by image forming material owing to using, the most visible), in figure, dark circles speckle represents affected part, the mark in each coordinate setting portion is as it can be seen, now determine that affected part position is horizontal indicated by the longitudinal direction indicated by No. 1 coordinate setting portion and b coordinate setting portion.
(4) contrast scans image and patient's actual wear state, the two location lines finding the location line connected in No. 1 coordinate setting portion on positioning cap and be connected respectively in b coordinate setting portion, then the optional position on two location lines all can be as executing art position, and executing the art degree of depth is the position that above-mentioned 4th depth localization portion 11 is demarcated.Preferably, can from cap body the intersection point in described coordinate setting portion 12 and depth localization portion 11, the point of intersection (corresponding patient's frontal bone) in the coordinate setting portion 12 of i.e. No. 1 coordinate setting line upper end and the 4th depth localization portion, or point of intersection (the corresponding patient's temporal bone) place in the coordinate setting portion 12 of b coordinate setting line right-hand member and the 4th depth localization portion, level punctures, to ensure accuracy rate.Due to before by according to scanogram, it has been determined that the particular location of affected part, therefore can execute art position and the line of affected part position according to selected, determine lower pin angle and the degree of depth, to ensure the accuracy of operation.
It should be noted that this reference example is simply to illustrate that the using method of scheme, the numerical value in reference example is not intended to limit protection domain of the present utility model.
In an alternate embodiment of the invention, described depth localization portion 11 be shaped as ring-type arrowband；Distance between adjacent two described depth localization portions 11 is 0.5-2 centimetre.

In an alternate embodiment of the invention, the distance between adjacent two described depth localization portions 11 is 1 centimetre, and this is also the most frequently used scanning resolution of intracranial imaging.
In an alternate embodiment of the invention, described location line includes the first location line 21 and the second location line 22；Any two described first line 21 place, location planes are parallel to each other, and any two described second line 22 place, location planes are parallel to each other；Any two described first location lines 21 are mutually perpendicular to described second line 22 place, location plane.
When the positioning cap provided for patient worn the present embodiment, it shall be noted that by the first location line 21 or the second location line 22, a location line coplanar with described main body 1 diameter is just to patient's skull median plane, in order to be accurately positioned.
In an alternate embodiment of the invention, the distance between adjacent two described first line 21 place, location planes or between adjacent two described second line 22 place, location planes is the first distance；Described first distance is 0.5-2 centimetre.First distance determines setting accuracy, and first apart from excessive, can cause positioning inaccuracy, it is impossible to play corresponding effect；First is the most intensive apart from too small then location line, affects doctor and executes art.Accordingly, it would be desirable to choosing suitable length as the first distance, preferably length range is 0.5-2 centimetre.
In an alternate embodiment of the invention, described first distance is 1 centimetre.This is empirically determined optimum distance, simultaneously can also be corresponding with distance between depth localization portion 11 described in above-mentioned two, it is simple to location Calculation.
In an alternate embodiment of the invention, the height of described main body 1 is 6-10 centimetre.One of effect of described main body 1 determines that the affected part degree of depth, when affected part depth ratio is shallower, can readily determine that position, even if can also accurately not determine the affected part degree of depth by main body 1, if simultaneously main body 1 arrange too high time, main body 1 top can be caused cannot to fit completely with patient's scalp, the most just cannot be accurately positioned, lose effect；The height of described main body 1 need not the too high of setting.Meanwhile, it is too low that the height of main body 1 can not be arranged, and otherwise cannot relate to the affected part that the degree of depth is moderate.It is therefore advantageous to span be 6-10 centimetre.
In an alternate embodiment of the invention, the height of described main body 1 is 8 centimetres, and this is to rise with temporal bone bottom upwards to calculate, and affected part the most often occurs, be the most more difficult to the region that positions.
Fig. 3 is the schematic perspective view that a kind of skull disclosed in this utility model punctures the alternative embodiment of auxiliary positioning cap.As it can be seen, in an alternate embodiment of the invention, described main body 1 disconnects along a bus, and gap is connected by elastic bands 3.Cannot adapt to, in order to avoid main body 1 deformation quantity is not enough, the patient that build is bigger, maybe cannot reach to fit completely to the patient that build is less, therefore elastic bands 3 is set to better adapt to the sufferer of different building shape.It should be noted that when wearing, for patient, the positioning cap that the present embodiment provides, it should elastic bands is placed in hindbrain etc. and does not interferes with the position executing art.
As can be seen from above, a kind of skull that this utility model provides punctures auxiliary positioning cap by arranging depth localization portion and coordinate setting portion, three-dimensional system of coordinate is established for patient's skull, affected part position can be accurately determined in three-dimensional system of coordinate in conjunction with intracranial imaging results, determine according to location line further and execute art position, thus solve related surgical in prior art and only rely on doctors experience and execute the problem of art, substantially increase the safety of operation.
