Problems solved by technology

Due to the complex anatomical structure of the perineum and prostate, the doctor holds the ultrasonic probe and the puncture needle to puncture during the operation, which may easily damage the patient's tissue. At the same time, because the bacterial environment in the rectum is complex and difficult to disinfect, it is easy to introduce pathogens and cause complications in the patient. disease
Therefore, needle biopsy puts forward higher requirements on the professional level of doctors, which limits the screening of prostate cancer

Abstract

The invention provides a prostate biopsy puncture robot based on biplane ultrasonic image guidance. The prostate biopsy puncture robot comprises an angle control mechanism, a fixing mechanism, a vertical position adjusting mechanism and a puncture executing mechanism, wherein the angle control mechanism is used for adjusting the angles of an ultrasonic probe and a puncture overall mechanism; the fixing mechanism is supported on the angle control mechanism through a shafting and a relevant connecting piece and is used for clamping the ultrasonic probe; the vertical position adjusting mechanism is used for adjusting the distance between a puncture needle and the ultrasonic probe; the puncture executing mechanism is used for pushing the puncture needle; the vertical position adjusting mechanism is arranged on the shafting of the angle control mechanism through the connecting piece; and the puncture executing mechanism is fixedly arranged on a sliding table of the vertical position adjusting mechanism. According to the prostate biopsy puncture robot, ultrasonic images in two different planes of the prostate part of a patient are acquired through the transrectal ultrasonic probe, and the puncture needle is accurately controlled by moving the angle control mechanism, the vertical position adjusting mechanism and the puncture executing mechanism.

Description

technical field [0001] The invention relates to a technology in the field of medical devices, in particular to a prostate biopsy puncture robot guided by ultrasound images. Background technique [0002] In the early diagnosis of prostate cancer, it mainly relies on rectal ultrasound-guided transperineal or transrectal biopsy of the prostate. Due to the complex anatomical structure of the perineum and prostate, the doctor holds the ultrasonic probe and the puncture needle to puncture during the operation, which may easily damage the patient's tissue. At the same time, because the bacterial environment in the rectum is complex and difficult to disinfect, it is easy to introduce pathogens and cause complications in the patient. disease. Therefore, needle biopsy puts forward higher requirements on the professional level of doctors, which limits the screening of prostate cancer. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, th...
