A precise positioning auxiliary device for transperineal prostate puncture

Abstract

The invention relates to an auxiliary device for accurate positioning of transperineal prostate puncture, which includes a puncture bracket and a support seat. The chute is provided with a slide plate that can slide and be fixed along the chute. One end of the slide plate is fixed with a puncture guide plate perpendicular to the axis of the snap sleeve. Groove; the upper surface of the support seat is fixed with a locking positioning plate and a puncture angler for passing through the probe base, the locking positioning plate can fix the probe base, and the puncture angler can measure the angle between the puncture guide plate and the horizontal plane.

Description

technical field [0001] The invention belongs to the technical field of puncture positioning, and in particular relates to a precise positioning auxiliary device for transperineal prostate puncture. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, prostate biopsy has become the gold standard for the diagnosis of prostate cancer. There are various puncture methods, including transrectal puncture, transperineal puncture, systematic puncture, saturation puncture, and targeted puncture with image fusion. With the continuous advancement of technology, image fusion targeted puncture has become the mainstream of prostate puncture. The main methods of targeted puncture include direct puncture, software fusion and cognitive fusion. At present, transperineal free-hand cognitive fusion puncture is widely used because of its advantages of simplicit...

Problems solved by technology

[0005] (1) The position of the puncture needle and the ultrasonic probe is uncertain. Depending entirely on the experience of the medical staff, the ultrasonic probe may not be able to effectively detect the abnormal target area, and the positional relationship between the puncture needle and the abnormal target area cannot be accurately sensed. ;

[0006] (2) For imaging treatment obtained by nuclear magnetic resonance, etc., although simple measurement or the deviation angle and depth of the abnormal target area from the vertical center of the perineum can be performed, when the puncture is performed freely, the medical staff cannot The effective use of the measured deviation angle and depth values ​​is limited by the experience of medical staff
