Problems solved by technology

However, the traditional positioning puncture is limited by the straight shape of the puncture needle, and can only choose a straight path for puncture. If there is a tissue that is not suitable for puncture on a certain straight path, such as a tumor that is easy to bleed, or an interlobar fissure in the lung , bones such as scapula and ribs, etc., you can only give up the puncture path, and choose a farther or more difficult angle for puncture. What is more serious is that some patients have no other suitable puncture paths and can only give up treatment.

Abstract

The invention provides an arc-shaped puncture device and a using method thereof. The device comprises an arc-shaped puncture needle, an arc-shaped puncture needle guide tube and a guide tube positioning frame, wherein an arc-shaped puncture needle main body is matched with the arc-shaped puncture needle guide tube in an arc shape, so that the arc-shaped puncture needle can freely shuttle along thearc in the guide tube; positioning support points are arranged on the guide tube, so that the guide tube can be fixed on the positioning frame; the positioning frame can be fixed at a specific position of a human body; and a plurality of positioning points are arranged on the positioning frame, so that the guide tube can be positioned at different positions and angles.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an arc-shaped puncturing device and a using method thereof. Background technique [0002] When substantive diseases occur in the internal organs of the human body, especially tumors, in order to clarify the pathology or directly ablate the lesion, puncture is used. Currently, the commonly used method is to scan the human body with tomographic imaging equipment such as magnetic resonance or CT. Finally, the location and depth of the lesion and the skin needle insertion point are determined, and precise puncture is performed at the fault level where the lesion is located. However, the traditional positioning puncture is limited by the straight shape of the puncture needle, and can only choose a straight path for puncture. If there is a tissue that is not suitable for puncture on a certain straight path, such as a tumor that is easy to bleed, an interlobar fissure in the...
