Ultrasound-guided percutaneous puncture bone positioning device

Abstract

The invention discloses an ultrasonic-guided percutaneous puncture bone positioning device, comprising a puncture positioning needle and an ultrasonic puncture cannula, wherein the ultrasonic puncturecannula is an internal hollow cylindrical structure, and a positioning needle tunnel for puncture positioning needle to pass through is arranged inside the ultrasonic puncture cannula; At that frontend of the position needle tunnel, a positioning needle tunnel outlet is arranged, and at the rear end, a positioning needle tunnel inlet is arrange. A lingual arc-shaped ultrasonic probe is arrange at that front end of the ultrasonic puncture cannula, and the tunnel outlet of the positioning needle is locate at the head end of the lingual arc-shaped ultrasonic probe. The tongue-shaped arc-shapedultrasonic probe is provided with an electrode, and the tongue-shaped arc-shaped ultrasonic probe is provided with a lead assembly for transmitting information to an external host. By arranging an ultrasonic probe at the arc-shaped head end of the puncture cannula, real-time ultrasonic image data can be provided for the direction of the puncture needle when the puncture cannula is positioned withminimal trauma, so that the puncture needle avoids structures such as important nerves and blood vessels, avoids damage of the puncture aimed at important structures in the process of bone puncture positioning, and is simple in operation and more accurate in positioning at the same time.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ultrasound-guided percutaneous bone positioning device. Background technique [0002] When the cervical spine, thoracic spine, lumbar spine, pelvis, and extremity bones have lesions, due to their unknown nature, surgical biopsy is routinely required to confirm the lesions, and a definite diagnosis is required for further effective treatment. Conventional surgery has disadvantages such as large trauma, excessive bleeding, accelerated lesion spread, and increased risk of radical surgery. In recent years, with the continuous development of percutaneous technology, percutaneous puncture and biopsy under C-arm monitoring can avoid many shortcomings of open surgery. When the lesion is adjacent to important nerves, blood vessels or organs, percutaneous puncture will easily damage its adjacent important structures and cause serious complications. On the premise of C-arm ...
