Abstract

The invention provides a puncture needle positioning device for ultrasonic therapy, which relates to the technical field of positioning devices, and solves the problem that the elimination of empty back cannot be realized through structural improvement, which affects the positioning accuracy; if it is adjusted accidentally, it will easily lead to position deviation. Shifting, which requires readjustment, is a waste of time. A puncture needle positioning device for ultrasonic therapy, comprising a first adjustment structure and an adjustment rod structure; a second adjustment structure is installed on the first adjustment structure, and a positioning seat is welded on the second adjustment structure. Because the stop ring is welded on the threaded rod, and there is an elastic part B sleeved on the threaded rod; the head end of the elastic part B is in contact with the stop ring, and the tail end of the elastic part B is in contact with the handle, and pushed by the elastic force of the elastic part B The handle is in a non-contact state with the protrusion, so that the threaded rod will not be rotated when the handle is touched unintentionally.

Description

technical field [0001] The invention belongs to the technical field of positioning devices, and more specifically relates to a positioning device for a puncture needle for ultrasonic therapy. Background technique [0002] Percutaneous puncture surgery is a minimally invasive surgery, and doctors can apply it in, for example, lung tumor puncture, liver tumor puncture, percutaneous liver puncture biliary drainage, end-cancer pain blocking, etc.; when performing percutaneous puncture surgery, doctors often Combined with computerized tomography to assist doctors in judging the puncture position of the puncture needle. [0003] For example, the application number: CN201510906097.7, the present invention discloses a puncture needle positioning device. The puncture needle positioning device is suitable for adjusting and positioning the puncture needle. The puncture needle positioning device includes a back frame and a positioning mechanism. The positioning mechanism is arranged ...
