Abstract

The invention discloses an ultrasonic device with a guiding puncture needle. By setting a needle sending assembly and a power assembly, the automatic delivery of the needle into and out of the puncture needle can be realized, and the needle insertion accuracy of the puncture needle can be effectively controlled; On the device body, the adjustment component can adjust the angle of the guide frame, thereby adjusting the angle of the puncture needle, with high flexibility; at the same time, by setting the adjustment component, the guide frame can be stored into the storage slot to reduce the need for puncture. The cumbersome work of installing and dismantling the puncture frame can quickly store the guide frame through the rotating wheel; in addition, by setting the reciprocating component, the power component drives the reciprocating component to move, and at the same time, the clamping device drives the puncture needle to reciprocate. The calcified tissue of tenosynovitis or other calcified tissue is constantly impacted and smashed at a certain frequency to improve the efficiency of puncture for the calcified tissue of tenosynovitis or other calcified tissue.

Description

technical field [0001] The invention relates to the technical field of ultrasonic diagnosis and treatment, in particular to an ultrasonic device with a guiding puncture needle. Background technique [0002] The tendon sheath is a double-layer casing-like closed synovial tube that covers the tendon, and is the synovial sheath that protects the tendon. It surrounds the tendon in two layers, and there is a cavity between the two layers, the synovial cavity, which contains the synovial fluid of the tendon sheath. The inner layer is closely attached to the tendon, and the outer layer is lined inside the tendon fiber sheath, and together with the bone surface, it has the functions of fixing, protecting and lubricating the tendon, preventing it from friction or compression. Long-term excessive friction of the tendon can cause injury and inflammation of the tendon and tendon sheath, causing swelling, which is called tenosynovitis. [0003] When calcification occurs in tenosynoviti...
