[0030] The working principle of the disposable prostate puncture sampling device is described in detail below.

[0031] like Figure 1-5 As shown, when performing prostate puncture sampling on a patient, first, the position and specific point of the prostate gland tissue to be sampled are determined by using ultrasonic technology, and the lower end of the positioning pin 6 is inserted into the positioning groove 710 through the connecting hole 501 to position the puncture sampling component 7. Then, the medical staff squeezes the airbag ball 74 to discharge the air in the sampling sleeve 71 and the sampling needle 72, and then inserts the sampling rod 2 from the patient's anus according to the position and specific point of the prostate gland tissue sampling. When the puncture is in place, the rubber protrusion 21 is pressed against the outside of the prostate gland tissue for positioning, and the sampling rod 2 is stopped from sliding further, and the positioning plug is inserted. The pin 6 is pulled out from the connecting hole 501, and then the sampling sleeve 71 is pushed forward. During the pushing process, the ball 31 in the positioning sleeve 3 rolls along the rubber pad 712 on the limiting slide groove 711, so that the sampling needle 72 moves forward along the inside of the connecting groove 201 to the head of the sampling rod 2, and then the force applied to the airbag ball 74 is released, so that the airbag ball 74 rebounds, thereby cutting and sampling the prostate tissue through the sampling needle 72. In order to prevent the prostate tissue from falling, the sampling sleeve 71 is pulled back, and the positioning pin 6 is inserted into the positioning groove 710 for positioning, and then the sampling rod 2 is moved out of the patient's body to complete the sampling.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
