Problems solved by technology

[0004] The purpose of the present invention is to provide a positioning device for guiding puncture in CT image puncture, so as to solve the problems in the above-mentioned background technology that mostly rely on the doctor's experience and intuition, which is highly subjective and cannot position the puncture needle. It is inconvenient to use, and it is easy to cause secondary injury to the patient. The safety is low, the use is inconvenient, and the long-term puncture consumes a lot of energy. During the puncture process, there will be fluctuations in manpower due to excessive consumption, which will affect the accuracy of the puncture. Affected, the problem of a low success rate of puncture

Abstract

The invention relates to a positioning device for guiding puncture in CT image puncture in the technical field of medical instruments. The positioning device comprises a fixing device, the top of the fixing device is fixedly connected with a height adjusting device, the top of the height adjusting device is fixedly connected with a telescopic device, and the end part of the telescopic device is fixedly connected with an angle adjusting device. The end of the angle adjusting device is fixedly connected with a positioning sleeve, and the side surface of the positioning sleeve is rotationally connected with a body positioning device. The positioning device is simple in structure, convenient to fix, rapid in positioning, capable of avoiding secondary injury to a patient, 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 the body cavity to extract secretions for testing, inject gas or contrast agent into the body cavity for contrast examination, or inject drugs into the body cavity. The purpose of puncture is to draw blood Laboratory tests, blood transfusion, infusion, and catheter placement for angiography, etc. With the development of CT technology, there are many diseases that can be clearly visualized by CT. However, to clarify the nature of the lesion, a biopsy is required. The position of the needle As well as the angle, it is mostly judged by the doctor's experience and intuition. It is highly subjective and cannot be used to locate the puncture needl...
