Abstract

The invention relates to a puncture-needle guiding device and a puncture frame adopting the device. The puncture-needle guiding device comprises a pedestal and an upper cover, wherein the certain opposite sides of the pedestal and the upper cover are rotatably connected, the other opposite sides of the pedestal and the upper cover are connected through clamping and buckling, a needle slot is formed in the pedestal, and an elastic cantilever which covers the needle slot when the upper cover rotates to be buckled with the pedestal is arranged on the upper cover. The puncture frame comprises an angular supporting seat and the puncture-needle guiding device, wherein the puncture-needle guiding device is detachably installed on the angular supporting seat. Therefore, the puncture-needle guiding device and the puncture frame have the advantages of simple structure, adaptability to any needle type and convenience in needle-frame separation.

Description

technical field [0001] The invention relates to a puncture frame used in conjunction with medical imaging equipment, more specifically, to a puncture needle guiding device and a puncture frame using the device. Background technique [0002] At present, puncture diagnosis and treatment technology combined with medical imaging equipment has been widely used in the diagnosis and treatment of various diseases. Inserting the puncture needle into the human body and reaching the puncture target needs to be completed under the support and guidance of the puncture frame. For example, ultrasonic interventional diagnosis and treatment need to configure a puncture frame for the ultrasonic probe, and use puncture needles for puncture operations. The puncture needles have various types according to different diameters. Utilizing the real-time monitoring of the puncture needle by ultrasound images, the puncture needle can be more accurately guided to the puncture target with the support o...
