Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing puncture positioning device can only perform vertical positioning, which is inconvenient for the puncture needle to puncture in an inclined manner, and usually can only be displaced in one direction for position adjustment, and the positioning range is small. The work of medical staff brings difficulties and disadvantages, and a cardiology puncture positioning device is proposed

Abstract

The invention belongs to the technical field of medical instruments, particularly relates to a cardiology puncture positioning device, and aims at solving the problems that an existing puncture positioning device can only conduct vertical positioning, a puncture needle cannot conduct puncture in an inclined mode, generally, position adjustment can be conducted only through displacement in one direction, the positioning range is small, and difficulty is caused to work of medical staff. In order to solve the problem, the invention provides the following scheme that the cardiology puncture positioning device comprises a first supporting column and a second supporting column; a first rotating shaft and a second rotating shaft are rotationally mounted on the sides, close to each other, of the first supporting column and the second supporting column correspondingly; and the ends, close to each other, of the first rotating shaft and the second rotating shaft are fixedly connected with the same rectangular block. According to the puncture positioning device, the inclination angle of a guide tube can be adjusted through a second rotary button, a puncture needle can conveniently conduct puncture in an inclined mode, the guide tube can do annular motion to increase the size of the positioning range, and operation of medical staff is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a puncture positioning device for cardiology. Background technique [0002] At present, clinically, puncture needles are mainly used when puncturing patients for pleural effusion. Patients with pericardial puncture can understand the nature of pericardial effusion by testing the fluid in the pericardial cavity, and find out the cause of pericarditis according to the nature of pericardial effusion. cause. In addition, when there is a large amount of effusion in the pericardium, the blood circulation of the patient is seriously disturbed, the venous blood cannot return to the heart smoothly, and the heart's blood drainage function is impaired. The release of a large amount of effusion by pericardial puncture can relieve the patient's symptoms or even disappear; [0003] However, the existing puncture positioning devices can only be positioned vertically, which is inconveni...
