Embodiment
Referring to shown in Fig. 1 to Fig. 3：The invention discloses a kind of centrum puncture locator, for determining the thorn that centrum 6 punctures
Point position and puncture angle.The present invention can not only quick puncture positioning, to puncture accuracy high, and ensure that reduction X-ray
Line irradiation number of times, shortening operating time, the accident in reduction operation and the infection in operation, the therapeutic effect for improving operation.Should
Used in Medical Instruments technical field, therefore it is preferred that, the centrum puncture locator is made of Medical polyethylene material.
The centrum puncture locator includes transverse presentation scale 1, vertical position scale 2, puncture needle sleeve pipe 5 and its angular adjustment dress
Put, the transverse presentation scale 1, the vertical square crossing of position scale 2, intersection point arbitrarily can be slided and locked, this implementation along the two ends of transverse presentation scale 1
Transverse presentation scale 1, vertical position scale 2 are linked together using hinge 13 in example, the bottom of the hinge 13 is locked by locking member.It is excellent
Choosing, the hinge 13 coordinates the radial section of the part of bar shaped chute 11 on transverse presentation scale 1 square-shaped.In order to ensure horizontal stroke
Position scale 1 and the vertical square crossing of position scale 2.
The angle regulator of the puncture needle sleeve pipe 5 is made up of Coronal Angle protractor 3 and sagittal plain Angle protractor 4, described
Coronal Angle protractor 3 is arranged on transverse presentation scale 1 by vernier prostration, can be appointed by the first vernier 12 along the two ends of transverse presentation scale 1
Meaning is slided and locked, and the trip bolt 14 of locking action has been provided with first vernier 12, and the projection of its center of circle falls in transverse presentation mark
On the axis of chi 1；The sagittal plain Angle protractor 4 is erect by hinge 43 and is arranged on Coronal Angle protractor 3, the hinge bottom
Extend the lower surface of bar shaped chute 11 on transverse presentation scale 1, and the nut 44 of locking action is locked by, the projection of its center of circle falls in horizontal stroke
On the axis of position scale 1, and overlapped with the center of circle projection of Coronal Angle protractor 3.Wherein, sagittal plain Angle protractor 4 is erect into cloth
Put the hollow structure of hinge 43 on Coronal Angle protractor 3 for axial direction, with ensure puncture needle under different regulation angles it is suitable
Profit is by the hinge 43 of hollow structure and arrives at the point of puncture N above patient's body epidermis.
The puncture needle sleeve pipe 5 is arranged in the arc chute 41 on the facade of sagittal plain Angle protractor 4 by the second vernier 42
On, its center line is consistent with the radial graduation mark of sagittal plain Angle protractor 4, simultaneously, it is ensured that the second vernier 42 is in sagittal plain angulation
Slide and lock on arc chute 41 on the facade of plate 4, so as to drive facade of the puncture needle sleeve pipe 5 along sagittal plain Angle protractor 4
On arc chute 41 on reciprocatingly slide；The second vernier 42 is adjusted, puncture needle sleeve pipe 5 is can adjust on sagittal plain Angle protractor 4
Setting angle, that is, puncture needle sleeve pipe 5 is in the luffing angle α of vertical direction；Turn sagittal plain Angle protractor 4, can adjust sagittal plain
Fit angle of the Angle protractor 4 on Coronal Angle protractor 3, that is, 5 deflection angle in the horizontal direction of adjustment puncture needle sleeve pipe
Spend β；The first vernier 12 is adjusted, point of puncture N and lesion centrum target spot 62 offset distance L is can adjust.That is, lesion centrum target spot 62 is being just
Top correspondence hinge 13 center, point of puncture N determined by patient's epidermal location above datum mark M to patient's body epidermis
Distance.Wherein, the meter full scale of the Coronal Angle protractor 3 is 0~180 °, and it is shaped as semicircle；The sagittal plain amount
The meter full scale of gusset 4 is 0~180 °, and it is shaped as semicircle.
The puncture needle sleeve pipe 5 is open tube, and tube wall has longitudinally through opening.To facilitate the shifting of observation and puncture needle
Remove.
A kind of operating method of centrum puncture locator of the present invention is as follows：
Operation consent, the lesion centrum target spot 62 and lesion centrum spinous process central point for determining to puncture by CT 3 Dimension Image Techniques
61 position, the thorn point position of centrum 6 and puncture angle when being performed the operation by computer measurement, you can adjustment puncture needle sleeve pipe 5 exists
Setting angle on sagittal plain Angle protractor 4, that is, puncture needle sleeve pipe 5 is in the luffing angle α of vertical direction；Turn sagittal plain angulation
Plate 4, can adjust sagittal plain 4 fit angle on Coronal Angle protractor 3 of Angle protractor, that is, adjustment puncture needle sleeve pipe 5 is in level
The deflection angle beta in direction；Marked on the stereopsis of CT 3 Dimension Image Techniques lesion centrum spinous process central point 61 just on
Datum mark M, is also the center of hinge 13 at transverse presentation scale 1 and the vertical joining of position scale 2 determined by square patient's epidermal location,
And the datum mark M of arrangement is measured at the home position of sagittal plain Angle protractor 4（Actual at home position is exactly patient's body table
Point of puncture N above skin）Between need the distance of setting, i.e. the correspondence center base of hinge 13 directly over measurement lesion centrum target spot 62
The distance of point of puncture N above M to patient's body epidermis on schedule；
In operation, first, centrum 6 is had an X-rayed by mobile C-arm X-ray machine, the position of patient is adjusted, finds in lesion centrum spinous process
The datum mark M of the surface patient's epidermis of heart point 61, and the lesion centrum spinous process central point 61 and lesion centrum spinous process central point 61
The datum mark M of surface patient's epidermis line is perpendicular to putting down that bolt angle locater transverse presentation scale 1 and vertical position scale 2 are constituted
Face.On this basis, at the surface patient's epidermis of lesion centrum spinous process central point 61 on patient's body on find datum mark M
And longitudinally each line of spinous process central point 61 top corresponds to the supracutaneous line of patient's body to mistake datum mark M body, by angle
The joining of the transverse presentation scale 1 and vertical position scale 2 of spending position indicator is correspondingly placed at the base directly over the lesion centrum spinous process of patient
On schedule at M positions, and vertical position scale 2 was arranged in datum mark M body longitudinally correspondence above each line of spinous process central point 61
On the supracutaneous line of patient's body.
In operation, the offset distance L and three-dimensional viewpoin of the puncture needle sleeve pipe 5 of puncture locator are then adjusted and fixed（Pitching
Angle [alpha] and deflection angle β）.
In operation, finally under the irradiation of centrum X-ray, puncture needle is inserted by lesion centrum target spot by puncture needle sleeve pipe 5
Puncture locator is removed after the completion of 62 positions, and puncture.
Above concrete technical scheme is only to illustrate the present invention, rather than its limitations.Although with reference to above-mentioned particular technique side
The present invention is described in detail case, it will be understood by those within the art that：It still can be to above-mentioned specific
Technical scheme is modified, or carries out equivalent substitution to which part technical characteristic；And these modifications or replacement, do not make
The essence of appropriate technical solution departs from the spirit and scope of the present invention.
