Prostate puncture device with three-way structure and using method thereof

Abstract

The invention discloses a prostate puncture device with a three-way structure and a using method of the prostate puncture device. The prostate puncture device with a three-way structure comprises a puncture frame used for fixing a puncture needle and a transrectal ultrasonic probe, and further comprises a disinfection mechanism, and the disinfection mechanism comprises a sheath tube, a three-way connector, a silica gel sealing cover and a disinfectant injection system. The top and front and rear end interfaces of the three-way connector are respectively connected with the disinfectant injection system, the sheath tube and the silica gel sealing cover. The puncture needle penetrates through the silica gel sealing cover to move in the sheath tube; a guide channel is formed in the puncture frame, and the sheath tube is guided to slide back and forth in the guide channel. Accurate disinfection of rectal mucosa at a needle inserting point is achieved, meanwhile, the operation environment ofthe puncture needle is a closed space formed by the sheath tube and the three-way connector, the puncture needle and a puncture channel are completely isolated from the surrounding rectal bacterial environment, and the puncture needle and the surrounding space are in a completely sterile state during puncture. The prostate puncture device aims at guaranteeing that transrectal prostate puncture operation follows the surgical sterile principle to the maximum extent.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a transrectal prostate puncture positioner. Background technique [0002] Prostate biopsy guided by transrectal B-ultrasound is a key step in the diagnosis of prostate cancer. It is reported that more than 1 million prostate biopsies are performed in the United States every year. At present, the incidence of prostate cancer in China is increasing. Although there is no national statistics on the number of prostate biopsy operations, it is obvious that this diagnostic operation will become more popular with the development of prostate cancer screening and the aging population. Infection after puncture is the most common postoperative complication, and the pathogenic bacteria are mostly Escherichia coli, which cross the rectal mucosal barrier during transrectal puncture. About 1 / 4 of the patients after puncture, Escherichia coli colonized in the prostate tissue rich in blood supply t...
