Precise positioning auxiliary device for perineal prostate puncture

Abstract

The invention relates to a precise positioning auxiliary device for perineal prostate puncture. The precise positioning auxiliary device comprises a puncture support and a supporting seat, wherein the puncture support comprises a clamping sleeve which can be clamped outside a probe base body; a sliding chute is formed in the outer surface of the clamping sleeve along the axis direction of the clamping sleeve; a sliding plate which can slide along the sliding chute and can be fixed is arranged in the sliding chute; a puncture guide plate perpendicular to the axis of the clamping sleeve is fixed at one end of the sliding plate; a column of grooves of which the extending directions are parallel to the axis of the clamping sleeve are formed in the puncture guide plate; a locking positioning plate for penetrating through the probe base body and a puncture angle device are fixedly arranged on the upper surface of the supporting seat; the locking positioning plate can fix the probe base body; and the puncture angle device can measure an included 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
