Prostate puncture positioner integrated with flushing and disinfection three-way structure and puncture method thereof

Abstract

The present invention relates to medical devices. The prostate puncture positioner integrated with the flushing and disinfection three-way structure, including the puncture frame for fixing the puncture needle and the transrectal puncture probe, the head end of the puncture frame is flush with the head end of the transrectal puncture probe; The channel that guides the puncture needle to slide back and forth, and the channel is used to transport the disinfectant; the end of the channel is a three-way structure, and the three-way structure is integrated with the puncture frame; the rear end of the three-way structure is fixed with a sealed silicone seal Cover, the silicone sealing cover is used to pass through the puncture needle, and the puncture needle moves in the channel through the silicone sealing cover; the three-way structure is provided with an interface extending outward, and the interface is connected to the liquid outlet of a disinfectant injection system, and the disinfectant injection The system includes a storage chamber that stores a sanitizing solution. This patent realizes the sliding guide of the puncture needle with the traditional puncture frame, and at the same time, it can also realize the introduction of disinfectant, realize the precise disinfection of the rectal mucosa at the needle entry point and the complete aseptic state of the surrounding space when the puncture needle enters and exits the rectal mucosa.

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...
