The present invention discloses an ultrasonically guided angle-adjustable puncture device, comprising a suction cup, a
chassis, a bracket, a limit plate, a hook, a sliding block, a locking valve, an extension tube, an adjusting rod, a first adjusting valve, a second adjusting valve, a support, a pushing device, an ultrasonic probe, a probe fixing device, an adjusting device, a latex pad, a hanging plate, a converter, a
transmission line, a connecting plate and an adjusting tube, etc. The present invention has a reasonable and simple structure, low production cost, convenient installation and complete functions. The ultrasonic probe can be fixed by the probe fixing device, so that the puncture depth and angle can be calculated, which facilitates the accuracy of the surgical position and the calculation of the appropriate
insertion depth, so that the medical effect is better. By setting the adjusting device, adjusting the angle rod, fixing the angle by the fixing nut, and adjusting the angle scale line set on the upper surface of the block, the adjusted angle can be more accurate.
