However, the following problems have not been considered in the prior art: due to the body position of a patient, the C-arm operation technology and other reasons, the position of the puncture needle is often poor, and the puncture needle needs to be adjusted repeatedly, so that the operation time is prolonged, the exposure of X-rays in the operation is increased, and the emotion of an operator is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a percutaneous pedicle of vertebral arch location puncture ware to overcome present C arm location puncture technique and have the location inaccurate, puncture and X line expose etc. inadequately repeatedly.
The technical scheme of the utility model as follows:
a percutaneous pedicle positioning puncture outfit comprises a puncture positioning needle and a pedicle universal positioner which are matched with each other for use, wherein the pedicle universal positioner is a cylinder of a porous puncture tunnel with the center as a hollow and the diameter of 1.5mm, and a plurality of puncture needle tunnels with the diameter of 1.5mm are arranged in the pedicle universal positioner; the diameter of the puncture positioning needle is matched with that of a puncture needle tunnel in the universal pedicle positioner, and the diameter of the puncture positioning needle is preferably 1.4 mm; the puncture positioning needle adopts a steel needle structure, the head end of the positioning needle is a sharp needle point, scales are marked on the needle body, and the length of the positioning needle is longer than that of the pedicle of vertebral arch universal positioner by 5 cm. The tail end of the universal pedicle locator is internally concave in a buttonhole shape with a smooth periphery and a center, the head end of the universal pedicle locator is conical and is provided with tunnel openings with diameters corresponding to the tail end, and the conical head end is convenient for the implantation of a puncture positioning needle; the hollow tunnel is convenient for the puncture positioning needle to pass through.
The utility model designs the positioner into a porous tunnel with the center as a hollow, and the head end and the tail end of the positioner are correspondingly provided with holes; when the conventional pedicle of vertebral arch location is carried out, the pilot pin is implanted for the first time, the position of the pilot pin in the pedicle of vertebral arch is clearly determined through C arm perspective, the probability of once accurate location success is very low, especially when the position of the pilot pin needs to be properly moved, the situation that the pilot pin deviates from the ideal position often appears due to the tension action of back muscles, the position of the pilot pin needs to be adjusted repeatedly, C arm perspective is repeated at the same time, and the operation time and X-ray exposure are increased. When the positioning device is applied, the universal positioner can be implanted according to the position of the positioning needle after one-time positioning, and the positioning needle is implanted by selecting an ideal distance in combination with the positioning hole in the universal positioner, so that the positioning is accurately finished.
The utility model discloses a percutaneous pedicle of vertebral arch screw location puncture ware can realize safety, accurate puncture and the implantation of correct pedicle of vertebral arch screw, has realized that the wound is little, puncture advantages of wicresoft such as accurate, safe, high efficiency.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model discloses an implement like this:
as shown in figure 1, the utility model discloses a device is including puncture pilot pin 1 and the universal locator 5 of pedicle of vertebral arch that matches with it, and the left side is puncture pilot pin 1 in figure 1, and the right is the universal locator 5 of pedicle of vertebral arch. The puncture positioning needle 1 is a hard stainless steel needle which is not easy to bend, the diameter of the puncture positioning needle is about 1.4mm, the puncture positioning needle is 22cm long, the head end 4 of the puncture positioning needle is sharp, the tail end 3 of the puncture positioning needle is flat and blunt, and the scale 2 is marked on the latter half part by mm. The universal percutaneous pedicle locator 5 is a device which is porous, hollow and cylindrical, and the head end of the universal percutaneous pedicle locator is conical, a puncture tunnel 6 is arranged inside the universal percutaneous pedicle locator, and the plane arrangement of the puncture tunnel 6 is shown in figure 2.
Example 1:
as shown in fig. 3 and 4, the percutaneous universal pedicle locator 5 is 18cm long, the tail end of the percutaneous universal pedicle locator has a central opening a (D is 1.5mm), openings B \ C \ D \ E (D is 1.5mm) are respectively formed at the upper part, the lower part, the left part and the right part away from the hole a by 1.5mm, the tail end of the a \ B \ C \ D \ E is in a concave plum blossom shape, and openings F/G/H/I (D is 1.5mm) are respectively formed at the upper left part, the lower left part, the upper right part and the lower right part which are 2.5mm away from the hole a; the head end of the universal positioning device 5 for the percutaneous pedicle of vertebral arch is conical and about 1cm long, and the center and the periphery of the conical head end are respectively corresponding to openings with the diameters of A1, B1, C1, D1, E1, F1, G1, H1 and I1, so that the universal positioning device for the porous puncture tunnel 6 such as A-A1, B-B1, C-C1, D-D1, E-E1, F-F1, G-G1, H-H1, I-I1 and the like is formed.
