[0039] The ultrasonic probe uses ultrasonic detection technology to perform ultrasonic detection on the object to be detected or human tissue. While performing ultrasonic detection, it is sometimes necessary to perform a biopsy through a puncture needle, that is, to remove a small amount of prostate sample tissue in order to achieve the purpose of a clear diagnosis. The prior art provides a puncture device, which includes a needle slot plate, and the needle slot plate has a plurality of mounting holes for installing the puncture needle, so that the puncture needle can be selectively installed in a plurality of mounting holes to adjust the installation position of the puncture needle on the needle slot plate. Among them, the extension direction of the mounting holes is consistent with the extension direction of the probe, so that the extension direction of the puncture needle is always consistent with the extension direction of the probe. However, when the patient's prostate is large, part of the prostate will be blocked by the pubic bone, and the position of the mounting hole of the existing puncture device is relatively fixed, and the needle insertion path may be blocked by the patient's pubic bone.

[0040] In this regard, this embodiment provides a puncture assembly to solve the problem in the prior art that the mounting hole position of the puncture device is relatively fixed, resulting in the needle insertion path being blocked by the patient's pubic bone, and can be used in the field of ultrasonic detection equipment technology.
