Problems solved by technology
[0005] In order to make up for the deficiencies of the existing technology, the flexibility of the angle adjustment process of the positioning device in the prior art is low, the angle adjustment effect is not fine enough, and in the process of manual puncture and insertion, due to the obstruction effect of the human tissue layer on the puncture needle Different, in the puncture process, the operator needs to consume a lot of energy in order to ensure the smoothness of the puncture. At the same time, when human negligence leads to excessive use, it is easy to cause secondary injury to the patient and affect the progress of the operation.

Embodiment approach
[0039]As an embodiment of the present invention, the moving rod 23 is rotationally connected with the sliding rod 21; the rotating groove 22 is located on both sides of the moving rod 23 and is elastically connected to the limiting plate 5 by a spring; the limiting plate 5 is connected to the moving The interfaces of the rods 23 are all rough in design; an expansion bag 51 is fixedly connected between the limiting plate 5 and the rotating groove 22; 3 An extruding bag 52 is firmly connected between the side away from the first through groove 12 and the stretching member 32; the extruding bag 52 is fixedly connected in the stretching groove 3; the extruding bag 52 and the expansion bag 51 guide common design;
[0040] When working, by setting the extrusion bag 52, the expansion bag 51 and the limit plate 5, when the tension member 32 engaged with the limit groove 36 in the initial state breaks away from the limit groove 36 and enters the stretch groove 3 to the installation blo...

The invention belongs to the technical field of medical devices, and specifically relates to a cardiology puncture positioning device, which includes a main body mechanism, a positioning mechanism and a puncture mechanism; the main body mechanism includes a support frame and a connecting clip; the support frame is an "L" shape Plate-shaped structure; the connecting clips are designed in plural and symmetrically fixed on both sides of the "L"-shaped bottom end of the support frame; the present invention double-positions by setting a moving rod and a positioning plate, first adjusting in a large range and then finely adjusting, and at the same time cooperating with The positioning laser light can accurately locate the puncture position of the patient. At the same time, the traditional force is directly applied to the puncture needle for puncture. Through the engagement of the driving wheel and the driven wheel, the rotation force is converted into thrust to drive the puncture needle to move. It can effectively make the operation of the puncture needle more stable and it is easier to control the strength, thereby effectively controlling the movement rate of the puncture needle, and avoiding the secondary injury caused by the puncture to the patient caused by excessive force during the puncture process.
Description
technical field [0001] The invention belongs to the technical field of medical devices, in particular to a puncture positioning device for cardiology. Background technique [0002] In the medical operation of the prior art center, pericardial puncture is often performed to release a large amount of effusion in order to reduce the effusion in the patient's body. When performing conventional manual puncture operations, medical staff are required to have rich operating experience, and the medical staff need to spend a lot of energy during the operation. and time, and at the same time, when the puncture is performed by manpower, the shaking of the puncture needle will cause the puncture path to be dislocated, which is likely to cause secondary injury to the patient. Differently, the operator needs to consume a lot of energy in order to ensure the smoothness of the puncture during the puncture process. At the same time, when human negligence causes excessive force, it is easy to ...
