The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
As shown in Figure 1, this utility model comprises fixed mount 1, angle measurement unit 2, puncture needle guide catheter 3 and pointer 4, and wherein angle measurement unit 2 is fan-shaped, and the angle measurement unit 2 of present embodiment is 1/4 circle; Said puncture needle guide catheter 3 is articulated in the front (promptly having graduated one side) of angle measurement unit 2; The centrage of puncture needle guide catheter 3 is through the center of circle of angle measurement unit 2; Puncture needle passes said puncture needle guide catheter 3, stabs to want site of puncture 6; Pointer 4 is positioned at the back side of angle measurement unit 2, and an end of pointer 4 links to each other with the hinge of puncture needle guide catheter 3, rotates with puncture needle guide catheter 3, and the other end of pointer 4 is a free end.The front of angle measurement unit 2 is provided with two groups of arcual scales; One of them scale is a depth value; Another is the puncture distance value; Two groups of arcual scales are concentric with 1/4 circle of angle measurement unit 2, and the curved scale that promptly is long radius is for to want the scale of site of puncture to the degree of depth 7 of skin, and the curved scale that is minor radius is for wanting the scale of site of puncture 6 to the distance of puncture needle guide catheter 3, i.e. puncture distance 8; On angle measurement unit 2, also have arcuate socket, 1/4 circle of two curved scales on this arcuate socket and the angle measurement unit 2 and angle measurement unit 2 parallels; Pointer 4 is provided with two pointers; One of them pointer is the other end of pointer 4; Circular arc outer rim by angle measurement unit 2 is wanted the scale of site of puncture to the degree of depth 7 of skin to its positive bending, sensing, and another pointer is passed and be bent to the scale of angle measurement unit 2 fronts, sensing puncture distance 8 by said arcuate socket.
Fixed mount 1 is a cuboid, and the one of which end is provided with U-lag, and the other end is connected with a straight flange of angle measurement unit 2, and the end face of cuboid is tangential on 1/4 circle of angle measurement unit 2; The bottom surface of said fixed mount (1) is provided with another perpendicular cuboid, and the free end of this another cuboid is provided with U-lag.
As shown in Figure 2; Ultrasonic probe 5 is " L " shape; The principle of this utility model is that the U-lag on the U-lag on the fixed mount 1 and said another cuboid is connected and fixed with two straight flanges of " L " shape ultrasonic probe 5 respectively, this moment L shaped ultrasonic probe 5 the bottom surface of bottom surface and angle measurement unit 2 on a horizontal plane.Adjustment wants site of puncture 6 to be positioned on the ultrasonic probe 5 bottom surface center lines; Can measure through ultrasonic instrument and to want the numerical value of site of puncture to the degree of depth 7 of skin; Ultrasonic probe 5 bottom surface mid points are known to the distance of puncture needle guide catheter 3; Just can obtain wanting the distance of site of puncture 6 through trigonometric function, i.e. the numerical value of puncture distance 8 and the angle (being the angle of pointer 4 on angle measurement unit 2) of triangle drift angle to puncture needle guide catheter 3.We precompute the angle value and puncture distance value of standard depth on angle measurement unit 2 by this method, and on angle measurement unit 2, are recorded as depth value scale and puncture distance value scale.
