Abstract
The utility model discloses a thoracic vertebral pedicle sagittal deflection angle indicator which is characterized in that one end of a vertebral plate contact lever (1) is connected with a V-shaped bilateral fixing rod (2), the upper end of which is connected with a fan-shaped angle ruler (3), the center of the arched edge of the fan-shaped angle ruler (3) is a zero scale mark, scale marks on the two sides of the zero scale mark are symmetrical, a puncture pricker limiter (4) is connected to the fan-shaped angle ruler (3) in a sliding mode, a limiting pointer (5) is arranged right in the middle of the front side of the puncture pricker limiter (4), a longitudinal V-shaped groove (7) is formed right in the middle of the back side of the puncture pricker limiter (4), and the line connecting the point where the vertebral plate contact lever (1) is connected with the bilateral fixing rod (2) with the zero scale mark of the fan-shaped angle ruler (3) is perpendicular to the vertebral plate contact lever (1). The thoracic vertebral pedicle sagittal deflection angle indicator is simple in structure, practical, convenient to use and operate, safe, reliable, easy to operate, and capable of increasing the success rate of thoracic vertebral pedicle puncture, reducing the vertebral pedicle piercing risk, reducing the nerve injury risk, and shortening surgery time.
Description
Technical field:
This utility model relates to a kind of thoracic vertebral pedicle sagittal Deflection gauge, belongs to field of medical article technology.
Background technology:
At present, thoracic vertebral pedicle is put nail technology having relatively high expectations to level angle and sagittal drift angle clinically.Thoracic vertebral pedicle is thinner, and venipuncture difficulty is large compared with lumbar vertebra, especially goes up the more difficult control in thoracic vertebra sagittal drift angle.Existingly clinically be applied to thoracic vertebral pedicle to put the instrument of nail be horizontal deviation angle meter, it is by perpendicular to the ground the prostrate patient sagittal plane of health that makes, guide and can read puncture awl and sagittal level angle by gravitational effect, but because the physiological bending of thoracic vertebra exists, the sagittal angle of each vertebral body vertebral arch cannot be measured by gravitational effect, has reduced like this success rate of thoracic vertebral pedicle puncture, has increased pedicle of vertebral arch and has penetrated risk, the risk that has increased nerve injury, has extended operating time.
Utility model content:
It is a kind of simple and practical that the purpose of this utility model is to provide, and uses easy to operate, safe and reliable, simple to operate, improve the success rate of thoracic vertebral pedicle puncture, reduce pedicle of vertebral arch and penetrate risk, reduce nerve injury risk, shorten the thoracic vertebral pedicle sagittal Deflection gauge of operating time.
The purpose of this utility model can reach by following measure: a kind of thoracic vertebral pedicle sagittal Deflection gauge, it is characterized in that it comprises vertebral plate contact lever, one end of vertebral plate contact lever connects V-type bilateral fixed bar, the upper end of bilateral fixed bar connects fan-shaped bevel protractor, the arc edge center of fan-shaped bevel protractor is zero degree graduation mark, the scale symmetry of zero degree graduation mark both sides, puncture awl limiter is slidably connected on fan-shaped bevel protractor, the center, front of puncture awl limiter is provided with spacing pointer, puncture awl limiter dorsal part center has been provided with longitudinal V-type groove, connecting line between the zero degree graduation mark of the junction point of vertebral plate contact lever and bilateral fixed bar and fan-shaped bevel protractor is mutually vertical with vertebral plate contact lever.
This utility model can produce following good effect compared with the prior art: this utility model can be by the preoperative pedicle of vertebral arch of each vertebral body and the angle of adjacent vertebral plate line measured on two-dimentional sagittal plain CT, control the sagittal angle of thoracic vertebral pedicle puncture awl, improve the success rate of thoracic vertebral pedicle puncture, reduce pedicle of vertebral arch and penetrate risk, reduce nerve injury risk, shorten operating time.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the rearview of Fig. 1;
Fig. 4 is the top view of the puncture awl limiter of Fig. 1.
Detailed description of the invention: the preferred forms of the present utility model below in conjunction with accompanying drawing elaborates:
Embodiment: a kind of thoracic vertebral pedicle sagittal Deflection gauge is (referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4), it comprises vertebral plate contact lever 1, one end of vertebral plate contact lever 1 connects V-type bilateral fixed bar 2, the upper end of bilateral fixed bar 2 connects fan-shaped bevel protractor 3, the arc edge center of fan-shaped bevel protractor 3 is zero degree graduation mark, the scale symmetry of zero degree graduation mark both sides, every little lattice represent 1 degree, puncture awl limiter 4 is slidably connected on fan-shaped bevel protractor 3, puncture awl limiter 4 can slide on fan-shaped bevel protractor 3, connecting line between the junction point 6 of vertebral plate contact lever 1 and bilateral fixed bar 2 and the zero degree graduation mark of fan-shaped bevel protractor 3 is mutually vertical with vertebral plate contact lever 1.The center, front of puncture awl limiter 4 is provided with spacing pointer 5, and puncture awl limiter 4 dorsal part centers have been provided with longitudinal V-type groove 7, can bore bar with puncture awl and fit tightly, and are used for controlling puncture awl angle.
In art, to vertebral plate contact lever 1 and neighbouring vertebral plate outer rim recess is contacted, junction point 6 is placed in puncture entry point level, the spacing pointer of puncture awl limiter 45 is fixing on fan-shaped bevel protractor 3 by the upper angle of measuring of preoperative CT, by longitudinal V-type groove of puncture awl limiter 47 and the laminating of puncture awl cone bar, the angle that puncture awl prolongs puncture awl limiter 4 punctures.
