It can be seen that, since movable support 12 is naturally urged by the spring toward base 11, since movable support 12 is fixed integrally with guide tube 37, the movement of movable support 12 can drive guide tube 37 and thus urge puncture needle 18 forward. However, the puncture needle guide assembly still needs to be restrained by the pressing rod 16 of the pressing part to move forwards, and the pressing degree of the pressing rod 16 and the puncture needle guide assembly is realized by operating the pressing part, so that the effect of controllable release is achieved.

In order to improve the restraining effect of the pressing component by adopting the spring thrust action, in the embodiment, the pressing pad 28 is further sleeved on the pressing rod 16 of the pressing component, the internal liner 29 is sleeved inside the puncture needle outer sleeve 17 corresponding to the pressing pad 28, the inherent resistance ring 30 is sleeved outside the guide pipe 37 of the puncture needle body, and the pressing pad 28 and the internal liner 29 form the pressing resistance to the resistance ring 30. After the pressure lever 16 is elastically compressed, a large resistance (friction) can be provided for the catheter, and the resistance degree between the pressure lever and the catheter 37 can be changed under different degrees of manual pressing of the elastic component, so that the propelling degree and the locking condition of the puncture needle can be controlled.

Example 3: in addition to embodiments 1 and 2, a further needle guide assembly is provided by further modifying the needle guide assembly 2 in order to create, in conjunction with the needle guide assembly, a third or fourth pig ovarian cyst piercing device.

In this embodiment, as shown in fig. 7, the movable support 12 includes an inner cavity 31, a pressing member 33 is sleeved in the inner cavity 31, a pressure sensor 32 is installed in the inner cavity and behind the pressing member 33, a signal line of the pressure sensor 32 is connected to a signal input end of a controller, a signal output end of the controller is used for controlling a switch of the negative pressure machine 5, a pressing ring 34 is disposed behind the base, and the pressing ring 34 corresponds to the pressing member 33 and can press against each other to enable the pressure sensor to have a pressure signal.

The present embodiment detects the limit condition between the movable support and the base by using the pressure sensor, and the negative pressure machine starts to work when the two reach the limit position, and the design purpose is to prevent the negative pressure machine from continuously working to suck unnecessary components or impurities under the condition that the puncture needle is not in place. The top pressure ring 34 in this embodiment is fixed at the rear side of the base, and on the basis of this embodiment, a clamping groove is formed at the rear side of the base, the top pressure ring 34 which is independently detached and replaced is installed, and pressure signals of different puncture depths are changed by changing the thickness of the top pressure ring 34 so as to adapt to different puncture depth requirements or different population treatment requirements.
