Positioning device for puncture guiding in CT image puncture

Abstract

The invention discloses a positioning device for puncture guiding in CT image puncture. The device comprises a telescopic rod, the upper end of the side face of the fixed end of the telescopic rod isprovided with a fastening rotary knob, the fixed end of the telescopic rod is provided with a base, and the upper surface of a clamping plate of the base is fixedly connected with the fixed end of thetelescopic rod; a telescopic end of the telescopic rod is provided with a first connecting piece, a first clamping piece of the first connecting piece is fixedly connected with the telescopic end ofthe telescopic rod, the upper end of the first connecting piece is provided with an adjusting device, the left end of an extending rod of the adjusting device is provided with a second connecting piece, and the side face of a second screw rod of the second connecting piece is movably sleeved with a connecting ring. The positioning device for puncture guiding in CT image puncture is simple in structure and convenient to fix, the position and angle of a positioning sleeve can be quickly adjusted and finely tuned, rapid positioning of a puncture needle is facilitated, secondary injuries to patients can be avoided, and the device is high in safety, easy to operate and convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a positioning device for guiding puncture in CT image puncture. Background technique [0002] Puncture is a commonly used surgical term in medicine. It is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting drugs into the body cavity. The purpose of puncture is blood test, blood transfusion, infusion, and catheter placement for angiography, etc. With the development of CT technology, many diseases can be clearly visualized by CT, but to clarify the nature of the lesion, a biopsy is required , the position and angle of the puncture needle are mostly judged by the doctor's experience and intuition, which is highly subjective and cannot be positioned for the puncture needle, which is inconvenient to use and l...
