Description
Technical Field
The utility model relates to the field of medical equipment research, concretely relates to fixed pipe of two-chamber for endocardium puncture injection.
Background
In clinic, when performing endocardium puncture injection, an endocardium puncture needle needs to be placed at an endocardium puncture position for puncture injection.
When the existing puncture needle punctures, because the heart always moves periodically, the endocardium puncture needle and the endocardium injection part are in a moving state, and in the process of puncture injection, the endocardium puncture needle moves backwards under the reaction force of a catheter, so that the endocardium puncture needle shifts, the preset puncture injection effect cannot be achieved, and the normal operation of the whole operation is influenced.
