The limiting rod 115 is fixedly arranged on one side of the inner cavity of the jack 112. A limiting hole 116 is opened on one side of the fixed post 114, and the limiting rod 115 is adaptively inserted into the inner cavity of the limiting hole 116.

[0043] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0044] Step 1: Before performing kidney puncture, first detect the puncture depth according to the ultrasonic instrument and adjust the position of the limit orifice plate 109. Rotate the rotating handle 1010. The rotating handle 1010 can drive the screw rod 106 to rotate. Under the action of the threaded rotation force on the outer wall of the screw rod 106, the screw rod 106 drives the floating block 107 to move up and down, so as to limit the floating block 107 under the restriction of the strip-shaped hole 108, so as to adjust the height of the limit orifice plate 109. By providing the limit orifice plate 109, the cylinder body 5 can be limited to avoid the puncture needle 8 from being inserted too deep and reduce the risk during the puncture process;

[0045] Step 2: When performing kidney puncture, fix the suction cup 3 on the waist of the child, and stick the mucosa 12 outside the skin to fix the positions of the cover body 2 and the tube column 1. Move the cylinder handle 7 and the needle handle 9 downward to drive the cylinder body 5 into the tube column 1, thereby driving the puncture needle 8 and the syringe tube 6 to move downward to puncture the waist of the child. After the syringe tube 6 and the puncture needle 8 are punctured, rotate the fixing cap 103 so that the fixing cap 103 screws in one side under the rotation of the external thread 104, so that the clamping handle 102 can rotate inward around one end of the housing 101 under the action of the inclined surface at one end of the clamping handle 102, so that the clamping handle 102 is clamped on the outer wall of the cylinder body 5, thereby positioning the cylinder body 5 and the syringe tube 6 and preventing the depth of the syringe tube 6 from shifting when the child moves the body;

[0046] Step 3: Press the insertion post 111 inward. The insertion post 111 can move inward and compress the spring 113 to drive the limit rod 115 to disengage from the inner cavity of the limit hole 116, thereby releasing the position limit of the fixed post 114. Furthermore, the needle handle 9 can be moved upward to withdraw the puncture needle 8. By connecting and fixing the needle handle 9 and the cylinder handle 7, the puncture needle 8 and the syringe tube 6 can move smoothly, and the operation safety is relatively high, which is conducive to wide promotion.

The scope of the present invention is defined by the appended claims and their equivalents.
