Embodiment 1

[0016] Embodiment 1, with reference to Figure 1-4 , a transperineal puncture frame with adjustable puncture distance, comprising a puncture frame body 1, a puncture needle adjustment member that can slide up and down along the puncture frame body 1, and an ultrasonic probe fixing member 3 arranged at the lower end of the puncture frame body 1, the The puncture needle adjustment part includes an adjustment screw 21 and a puncture needle guide groove 23, and a plurality of puncture needle holes 24 of different specifications are arranged on the puncture needle guide groove 23.

[0017] In this embodiment, the ultrasonic probe fixing part 3 is used to fix the ultrasonic probe 100 to avoid relative movement between the ultrasonic probe 100 and the puncture frame 1, and the ultrasonic probe 100 performs ultrasonic exploration on the puncture site and determines the distance from the puncture point to the ultrasonic probe 100. Then adjust the position of the puncture needle regulat...

Abstract

The invention relates to the technical field of medical auxiliary instruments, in particular to a perineum puncture frame with an adjustable puncture distance. According to the technical scheme, the perineal puncture frame with the adjustable puncture distance comprises a puncture frame body, a puncture needle adjusting piece capable of sliding up and down along the puncture frame body and an ultrasonic probe fixing piece arranged at the lower end of the puncture frame body, and the puncture needle adjusting piece comprises an adjusting screw and a puncture needle guide groove; and a plurality of puncture needle holes with different specifications are formed in the puncture needle guide groove. The puncture frame has the advantages that the puncture needle adjusting part capable of being adjusted in a sliding mode is arranged on the puncture frame body, the puncture needle holes of different specifications are formed in the puncture needle adjusting part, and the ultrasonic probe fixing part arranged at the lower end of the puncture frame body is matched; the distance between the puncture needle adjusting piece and the ultrasonic probe can be adjusted according to a puncture point guided by the ultrasonic probe, the puncture accuracy is improved, and meanwhile the puncture needle adjusting piece and the puncture needle can be detached conveniently to be cleaned and disinfected.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary devices, in particular to a transperineal puncture frame with adjustable puncture distance. Background technique [0002] Prostate cancer is a malignant tumor that occurs in male prostate tissue. It is the result of abnormal and disordered growth of prostatic alveolar cells. When the screening finds that the serum PSA is significantly higher than the normal value, prostate B-ultrasound finds prostate nodules, and digital rectal examination finds prostate nodules. Nodules need to be biopsied by rectal prostate biopsy to obtain pathological results to confirm the diagnosis. At present, the puncture distance cannot be adjusted during the puncture process under the guidance of ultrasound. The puncture distance is the distance between the puncture needle and the ultrasonic probe, and the ultrasonic puncture frame produced by existing manufacturers cannot meet the above requirements.
