Problems solved by technology

However, ultrasound imaging is fast. Although it can be imaged in real time during the operation, due to the limited resolution of ultrasound images, the distinction between soft tissues in the image is not high. Tissues are pinpointed precisely, resulting in a purely ultrasound-based sampling method that is not very sensitive for cancer detection, only 60% to 85%

Embodiment Construction

[0047] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0048] The present invention mainly comprises two aspects:

[0049] One is that the structural improvement of the puncture set enables accurate prompting of the rotation angle during intraoperative operation; the other is that a personalized calculation method for the rotation angle is provided as a supporting tool.

[0050] 1) Structural improvement of the puncture kit

[0051] Analysis of the operation process:

[0052] During the operation, the patient lies flat, and the interventional doctor passes the rectal puncture kit through the rectum and enters the prostate. At around 6.5MHz, since the preoperative doctor has obtained the position of the lesion area in the medical imaging modality equipment, the interventional doctor selects the area of ​​interest based on experience to give needles, and divides the whole prostate into s...

Abstract

Disclosed are a removal method and apparatus capable of accurately operating a prostate puncture needle to carry out a biopsy. The traditional sextant biopsy is improved, i.e. improving equally dividing a whole prostate into six parts (the top, middle and bottom, and left and right sides of a prostate) before into only selecting a point to puncture in a region of interest. A clear and stereoscopic prostate lesion region can be completely provided to a doctor by means of preoperative image information. By means of adding an angle adjustment indication dial assisting apparatus, and computing, on the basis of preoperative planning, a needle point position, a planned route and a required puncture rotation angle, an improved puncture kit (9) can realize an accurate rotation operation, has higher precision and high individual specificity, and realizes accurate puncturing.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to a local puncture method for prostate lesion tissue and a calculation method for the spatial position of a puncture needle before operation. Background technique [0002] Prostate cancer is one of the most common cancers in men and the second deadliest among non-skin cancers. Currently, the most popular method of prostate cancer screening is serum prostate-specific antigen screening, followed by six or more biopsies guided by real-time 2D transrectal ultrasound. As part of this procedure, the prostate is usually divided into 6 equal volume regions. One or more biopsies were taken from each of these six regions in a systematic, but essentially non-directional fashion. This procedure is called a sextant biopsy. [0003] Sextant biopsy is widely used because of its low cost and simplicity relative to other methods of detecting prostate cancer. However, sextant biops...
