Experience, Chang Fanfu could be punctured successfully after trying positioning on, inherently increase operating time, ray exposure number, Yi Jiqi in this way
The incidence of chest/spitting of blood.Certainly, other percutaneous punctures operation can also encounter need carry out diagonal inserting needle situation, there is also because
Extend for the operating time caused by puncture angle inaccuracy, cause the problems such as patient's additional injury.
Utility model content
The utility model is intended to provide a kind of adjustable angle fixer of puncture needle, can be adjusted flexibly and fix puncture needle
Needle angle, so as to doctor operate.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows：A kind of adjustable angle of puncture needle is fixed
Device, including pedestal, workbench, bevel protractor, the bevel protractor is circular arc annular, and bevel protractor is equipped with scale, the bottom end of bevel protractor
It is connect with the right part of base upper surface, the left part of workbench left end and base upper surface is hinged by axis pin, axis pin and bevel protractor
Coaxial line, the right part of workbench are equipped with straight slot, and the both ends of straight slot extend through the upper and lower surface of workbench, straight slot and bevel protractor
Section is adapted to, and workbench left and/or right side is equipped with threaded hole, and threaded hole is connected with straight slot side wall, and screw is equipped in threaded hole,
Table surface is equipped with groove, and groove length is oriented parallel to bevel protractor radial direction, and groove runs through workbench left end and/or the right side
The end face at end.
Preferably, the bevel protractor is quarter circular arc annular.
Preferably, the plate upper surface is plane, and bevel protractor is located in vertical plane.
Preferably, the screw is hand screw.
Preferably, the workbench is transparent material.
Further, the groove is arranged on the upper surface of workbench.
Preferably, the groove is circular groove.
The utility model is designed reasonably, workbench can turn to any angle, straight slot and screw by axis pin with bottom plate
Setting can fix angle, the setting of groove can ensure that puncture needle needle angle is identical with lathe of work level angle, not only may be used
To adjust needle angle, additionally it is possible to which needle angle is constant during ensureing inserting needle, and doctor is facilitated to operate.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 uses schematic diagram for the utility model.
In figure：1- pedestals, 2- workbench, 3- bevel protractors, 4- axis pins, 5- straight slots, 6- threaded holes, 7- screws, 8- grooves,
9- scales.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown in Figure 1, a kind of adjustable angle fixer of puncture needle, including pedestal 1, workbench 2, bevel protractor 3, the angle
Ruler 3 is spent for quarter circular arc annular, and bevel protractor 3 is equipped with scale 9, and the numerical value of scale 9 is from the bottom end of bevel protractor 3 to top
Uniformly increase successively, the angle value of 3 bottom end of bevel protractor is 0 °, and 9 each lattice of scale are 1 °；
The bottom end of bevel protractor 3 is connect with the right part of 1 upper surface of pedestal, and 1 upper surface of pedestal is plane, and bevel protractor 3 is located at perpendicular
In facing directly, bevel protractor 3 is perpendicular to 1 upper surface of pedestal；
The workbench 2 is elongated rectangular shape or cylinder, and workbench 2 is transparent material, and 2 left and right directions of workbench is
Length direction, 2 length direction of workbench is parallel with the radial direction of bevel protractor 3, on the left end of 2 lower surface of workbench and pedestal 1
The left end on surface is hinged by axis pin 4, and axis pin 4 and 3 coaxial line of bevel protractor, the right part of workbench 2 are equipped with straight slot 5, straight slot 5
Both ends extend through the upper and lower surface of workbench 2, and straight slot 5 is adapted to 3 section of bevel protractor, and straight slot 5 is rectangle, and workbench 2 is left
Side and right side are equipped with threaded hole 6, and perpendicular to the side wall of straight slot 5, threaded hole 6 connects threaded hole 6 with the side wall of straight slot 5,
Screw 7 is equipped in threaded hole 6, screw 7 is hand screw, and 2 upper surface of workbench is equipped with groove 8, and groove 8 is circular groove,
8 length direction of groove is parallel to the radial direction of bevel protractor 3, and groove passes through 8 end faces for wearing 2 left end of workbench and/or right end.Groove
Angle between 8 and 1 upper surface of bottom plate is puncture needle needle angle, when 2 lower surface of workbench is contacted with 1 upper surface of bottom plate,
Groove 8 is parallel with bottom plate 1, and puncture needle needle angle is 0 ° at this time.
As shown in Fig. 2, in use, pedestal 1 is placed on body surface or is placed in table after 1 time placement support pad of pedestal
On face, bed surface, unscrew screw 7, puncture needle be placed in groove 8, make tip alignment entry point, adjust the right end of workbench 2,
