Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and specifically refers to a prostate puncture surgical device. Background Art

[0002] Prostate puncture surgery, medically known as prostate biopsy, is a medical procedure used to diagnose prostate cancer. This test may be performed for further diagnosis when the prostate-specific antigen level is elevated or the doctor finds abnormalities during a digital rectal exam. The tissue sample obtained will be sent to the laboratory, where a pathologist will examine it under a microscope to see if there are cancer cells. Based on the results of the examination, the doctor will decide whether further treatment or monitoring is needed. Prostate puncture biopsy is the gold standard for diagnosing prostate cancer. It is essential for early detection and treatment of prostate cancer and can effectively and timely understand the health of the prostate.

[0003] Puncture surgery usually involves rectal puncture biopsy and perineal puncture biopsy. Compared with rectal puncture, perineal puncture has almost no risk of infection, and the detection blind area is smaller than that of rectal puncture. During perineal puncture biopsy, the patient is required to lie flat on the bed. After local disinfection and anesthesia, the ultrasonic probe is inserted from the anus and pressed upward against the prostate in the rectum. Then the puncture needle is inserted from the perineum (between the male private parts and the anus) for sampling. Currently, in perineal prostate puncture surgery, only medical non-woven fabrics are usually used to cover the surrounding area. In the event of an operational error, other tissues of the patient may be harmed. Traditional methods cannot effectively protect patients.
