[0002] With the continuous development of medical technology, prostate biopsy plays a vital role in the diagnosis of prostate diseases. At present, the existing positioning devices for prostate biopsy mainly use targeted locators, which detect the position of the prostate through multi-parameter magnetic resonance imaging and present it in a grid. According to the grid positioning, the doctor inserts the puncture needle into the designated grid to accurately extract tissue samples.
[0003] However, this positioning method has some technical problems. On the one hand, for some tumors with a diameter less than 5 mm, if they are not in the grid gap, these lesions may be missed during the grid puncture process, thereby reducing the detection rate of the disease. On the other hand, it is usually necessary to conduct random inspections ten to twelve times, and the doctor needs to manually insert the puncture needle after determining the location.

The fourth 310 slides, and the puncture needle at one end of the puncture gun is inserted into the prostate through the perineum. The personnel presses the button on the side of the puncture gun to pop out the puncture end for random inspection. After completion, the electric telescopic rod 326 drives the limit seat 320 back to the original position, and the puncture needle is pulled out. The T-shaped block 1 324 continues to slide to one side of the electric telescopic rod 326, driving the telescopic rod 323 to slide outside the limit seat 320, and driving the T-shaped block 2 327 to slide inside the limit seat 320. The puncture gun is squeezed, and one end pops out to facilitate the doctor to take it out. The puncture gun can be driven by the electric telescopic rod 326 to directly puncture the perineum and puncture into the inside of the prostate, avoiding manual puncture, effectively reducing the workload, improving the accuracy of puncture, and improving the detection rate of the disease. The electric telescopic rod 326 drives the T-shaped block 1 324 to pull back, so that the T-shaped block 2 327 squeezes one end of the puncture gun, and the other end pops out to facilitate the doctor to take it out, effectively improving the convenience of operation.
