B ultrasonic guiding puncturing water sac for superficial phyma

The utility model relates to a shallow goiter B super steering puncturing water sac features simple structure, convenience and practicality, which is a rectangle water sac with certain thickness forming by a polyethylene film. A groove for placing needles is arranged on outer edge in the middle at the long edge side of the rectangle water sac which is full with distilled water through an injecting pipe. When used in small and medium-sized hospitals and basic medical care units, adopting the common belly standard frequency probe with low cost and adding the puncturing water sac in ultrasonic steering, which can push the shallow goiter to be probed to the media and far field, so as to improving the definition for displaying the goiter, which not only facilitates the ultrasonic steering, but also improves the accuracy for puncturing and avoids the damage to the tissues, blood vessel and organs near the goiter; in addition, the utility model can realize the observation for puncturing, tapping, injecting and the variation status in the goiter under Type-B ultrasonic. The puncturing water sac is economic and piratical and can be used repeatedly after sterilization, which is applicable not only for ultrasonic puncturing probe, but also for general probe.
