Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 2, an embodiment of the present invention provides a needle insertion angle measuring device for a puncture surgery, including a base 1, a semicircular dial 2 is disposed on the base 1, a swing rod 4 is disposed on a back surface of the dial 2, an end of the swing rod 4 is connected to a center of a circle of the dial 2 through a screw 6, a needle tube 3 is disposed on a front surface of the dial 2, the needle tube 3 is parallel to the swing rod 4, a first bracket 5 and a second bracket 7 are vertically connected between the needle tube 3 and the swing rod 4, a semicircular groove 8 is disposed on the dial 2, the groove 8 coincides with the center of the circle of the dial 2, and the second bracket 7 passes through the groove 8 and can slide along the groove 8.

In this embodiment, the circle center of the dial 2 is provided with a threaded hole, the end of the swing rod 4 is provided with a through hole matched with the threaded hole, and the screw 6 sequentially penetrates through the through hole and the threaded hole so as to fix the end of the swing rod 4 at the circle center of the dial 2.

As shown in fig. 2, an opening 31 is formed in the side surface of the needle tube 3, and the direction of the opening 31 is perpendicular to the plane of the scale 2 disc, so that the needle insertion angle measurer for the puncture surgery can be conveniently removed after use, and the subsequent operation of the surgery cannot be influenced.

As shown in fig. 1, the inside of the arc-shaped edge of the front surface of the dial 2 is marked with angle scales for observing the needle insertion angle, the range of the angle scales is 0-180 degrees, and specific angle values (not shown in the figure) are marked at intervals of 10 degrees.

In this embodiment, the base 1 is a rectangular frame structure, and is convenient for placement during surgery, and the diameter of the dial 2 is fixed on the central axis of the base 1.

As shown in fig. 1, the first support 5 is located outside the dial 2 and at the end of the swing link 4 and the needle tube 3, so that the structure is more stable.

In this embodiment, the cross-sections of the first support 5 and the second support 7 are circular, and the width of the groove 8 is adapted to the diameter of the second support 7, so as to increase the stability of the swing link 4 and the needle tube 3.

As shown in fig. 1, the swing rod 4 is flat and tightly attached to the back of the scale plate 2, so that the swing rod 4 can rotate relative to the scale plate 2.

The working principle of the needle insertion angle measurer for the puncture operation provided by the invention is as follows:

as shown in figure 1, the swing link 4, the first bracket 5, the second bracket 7 and the needle tube 3 can rotate around the screw 6 between 0 and 180 degrees, wherein the second bracket 7 moves in the semicircular groove 8, and the needle tube 3 is used for placing a puncture needle tube, so that the accuracy of the needle inserting direction can be ensured.
