Puncture device for ultrasonic interventional operation

Abstract

The puncture device comprises a fixing plate, a storage groove and an adjusting plate, a fixing shaft is fixedly connected to the right end of an inner cavity of the storage groove, an arc-shaped adjusting part is movably connected to the outer side of the fixing shaft, and a first angle line is arranged at the top of the arc-shaped adjusting part; an arc-shaped groove is formed in the inner surface of the arc-shaped adjusting piece, guide sliding grooves are formed in the two sides of an inner cavity of the arc-shaped groove, and guide sliding blocks are slidably connected to the inner sides of the guide sliding grooves. Through the effects of the arc-shaped adjusting piece, the star-shaped handle screw, the through hole, the guide sliding block, the threaded hole, the movable shaft, a guide sliding groove, a first angle line, a positioning adjusting screw, an adjusting plate, an arc-shaped positioning clamping plate and a second angle line, the problems that an existing puncture needle frame is fixed in structure, so that the puncture position and angle of a puncture needle are limited by the needle frame, and the puncture effect is poor are solved. The use is very inconvenient in the puncture process, and the use requirements of medical personnel are not met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a puncture device for ultrasonic interventional operations. Background technique [0002] Ultrasound interventional surgery has the advantages of minimal invasiveness, high efficiency and safety, and is not easy to cause complications. It belongs to minimally invasive interventional therapy. Ultrasound intervention mainly uses ultrasound guidance and needle puncture to enter the lower part of the human cortex, and performs operations such as biopsy, suction, drainage, and drug injection on the lesion area. With the technical development of ultrasonic medical treatment and interventional therapy, many special ultrasonic probes for ultrasonic intervention have appeared in the prior art, which can well realize ultrasonic interventional puncture. At the same time, some puncture needle holders that can cooperate with conventional ultrasonic probes are also disclosed. However,...
