Description

Adjustable ultrasonic probe guide puncture support Technical Field The utility model relates to the technical field of medical auxiliary equipment, in particular to an adjustable ultrasonic probe guiding puncture support. Background The ultrasonic probe guide puncture support is commonly called as an ultrasonic probe puncture frame, a puncture guide frame or a puncture guide, and is an important medical instrument, the ultrasonic probe puncture frame is an auxiliary device arranged on an ultrasonic probe, and a doctor can accurately guide a puncture needle to a target position of a human body under the real-time guidance of an ultrasonic image through the device, so that accurate puncture is realized. It is mainly used for the medical procedures such as cytological biopsy, histological biopsy, cyst aspiration and treatment. However, the existing ultrasonic probe guiding puncture support has the problems that the needle tube fixing assembly is arranged at the fixing position on the support, the needle tube fixing assembly can be adjusted only in a fixing range, and the needle tube fixing assembly is difficult to adjust according to the use habit of a user or the special situation facing during puncture, so that the device has certain limitation during use, and therefore, the adjustable ultrasonic probe guiding puncture support is provided for solving the problems. Disclosure of utility model In order to overcome the deficiencies of the prior art, at least one technical problem presented in the background art is solved.
