Description

Puncture fixing device

Technical Field

The utility model relates to the technical field of puncture, in particular to a puncture fixing device.

Background

Puncture is a diagnosis and treatment technology for puncturing a puncture needle into a body cavity to extract secretion for assay and the like. For example, pericardial puncture, which is commonly used in cardiology, is mainly performed by puncturing the pericardium with a puncture needle and extracting the effusion, and for example, by performing abdominal puncture for patients in hepatology to extract ascites for laboratory examination, etc.

When puncture is performed, two modes exist, one is that a doctor relies on own experience to puncture, and different doctors have different puncture levels; another is to use a puncture positioning device to guide the puncture.

For example, patent publication CN214511215U discloses a liver disease puncture positioning device in which puncture is assisted by a puncture guide provided, but assembly between the puncture guide and a cross bar is not convenient, and considering that the puncture guide is usually a disposable product, it is required to be detached from the cross bar after puncture is completed, so that assembly between the puncture guide and the cross bar is required to be more convenient, and in view of this, the utility model provides a puncture fixing device.
