Automatic ultrasonic-guidance prostate biopsy particle implanting system and acupuncture method

Abstract

The invention discloses an automatic ultrasonic-guidance prostate biopsy particle implanting system and an acupuncture method. A positioning module is fixed on a support platform, an image acquiring module is fixed on the support platform, and an operation module is mounted on the positioning module. The image acquiring module comprises an ultrasonic probe, a probe support and a head sleeve, the ultrasonic probe is movably arranged on the probe support, and the head sleeve is fixedly arranged in front of the ultrasonic probe; the operation module can be horizontally and uniformly inserted into a prostate focus by the positioning module, or can be diagonally inserted into the prostate focus by avoiding pubis or urethral canal in a manner of single or multiple tapered radiations. By adopting the positioning platform of six degrees of freedom, the automatic ultrasonic-guidance prostate biopsy particle implanting system can realize bi-cone coverage and be inserted into the focus parallelly or in any cone-shaped by avoiding pubis and other organs; by combining nuclear magnetic resonance/ultrasound images with image display and ultrasound in real time, biopsy positions can be accurately and visually identified, so that positioning is more accurate.

Description

technical field [0001] The invention relates to an ultrasound-guided automatic prostate biopsy particle implantation system and an acupuncture method. Background technique [0002] When a patient has suspected prostate cancer, a prostate biopsy is usually recommended. It is a surgical procedure in which a small portion of tissue is removed from the prostate as a sample and examined under a microscope by a pathologist or specialized doctor through the study of cells, tissues, and organs. The procedure takes about 15 minutes, is usually performed in a urologist's office, is used with transrectal ultrasound (TRUS), and usually does not require anesthesia. With the help of TRUS, a doctor directs a biopsy gun -- a hand-held, spring-loaded needle device -- through the wall of the rectum and into the area of ​​the abnormal prostate to take a sample. [0003] The rectal wall is thin, so the probe can be positioned more accurately with less damage to other tissues. When activated,...

Problems solved by technology

Therefore, the biopsy core only occupies about 0.6% of the volume of the prostate, and the random biopsy protocol is unlikely to guarantee a high detection rate of cancer when the cancer site is not accurately known;

[0008] 2. Inaccurate puncture. Although the biopsy is guided by TURS, it is known that under manual control, the biopsy needle may not be able to accurately
