Detailed Description
In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easy to understand, the following description and the accompanying drawings further illustrate the preferred embodiments of the invention.
Example (b):
as shown in figures 1 to 7:
the invention provides a kidney puncture device for nephrology department, which avoids needle handle slippage in the using process and comprises a puncture needle handle 1 and a mounting sleeve 2, wherein the outer side of the mounting sleeve 2 is rotatably provided with a torsion ring 3, the inner wall of the mounting sleeve 2 is movably inserted with fastening plates 4 which are uniformly distributed, the interior of the mounting sleeve 2 is fixedly provided with a vertical plate 5 inserted into the fastening plates 4, one side of the vertical plate 5 close to the torsion ring 3 is connected with a backing plate 7 through a pressure spring 6, one side of the backing plate 7 close to the torsion ring 3 is fixedly provided with an air bag I8, the inner wall of the torsion ring 3 is fixedly connected with a wedge block 9 corresponding to the fastening plates 4, the interior of the mounting sleeve 2 and below the fastening plates 4 are fixedly provided with an air bag II 10 corresponding to the wedge block 9, the air bag II 10 is communicated with the air bag I8 through a hollow ring 11 and a vent pipe 12, and the torsion;
wherein, the inner wall of the mounting sleeve 2 is provided with an open slot corresponding to the fastening plate 4, so that the fastening plate 4 can extend out and abut against the puncture needle handle 1;
two ends of the pressure spring 6 are fixedly connected with the vertical plate 5 and the base plate 7 respectively to ensure the stability of the pressure spring 6;
the same group of vertical plates 5, the pressure spring 6, the backing plate 7 and the first air bag 8 are all positioned in the fastening plate 4, and a sliding groove corresponding to the fastening plate 4 is formed in the fastening plate 4;
the part of the vent pipe 12, where the first air bag 8 is connected with the hollow ring 11, is provided with a flexible section, so that the first air bag 8 is always communicated with the hollow ring 11 when moving;
wherein, the interiors of the first air bag 8, the hollow ring 11 and the second air bag 10 are all filled with gas;
wherein, locating component 13 includes locating pin and reset spring, sets up the constant head tank that corresponds with the locating pin on the installation sleeve 2 for the swing ring 3 can be fixed after rotatory.
The working principle and the process of the invention are as follows:
in the invention, a puncture needle handle 1 is arranged on a kidney puncture device through an installation sleeve 2, and in an initial state, a fastening plate 4 is contracted in the installation sleeve 2 under the action of a pressure spring 6 and is not contacted with the puncture needle handle 1 so as to carry out normal installation and disassembly on the puncture needle handle 1, as shown in figure 2; the first air bag 8 and the second air bag 10 are communicated through a hollow ring 11 and a vent pipe 12, and the fastening plate 4 and the second air bag 10 are not in contact with the wedge-shaped block 9, as shown in fig. 5.
