Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a drag-reducing ultrasonic puncture needle capable of quickly determining the position of a needle tip. Background Art

[0002] During the puncture / drug injection / body fluid drainage and aspiration procedures, the puncture needle needs to be inserted into the human body. Existing ordinary puncture needles are not easy to be clearly developed under ultrasound. Unclear development will affect the positioning of the puncture needle, which may cause the puncture needle to damage nerves or accidentally injure surrounding organs. In addition, drug administration through the puncture needle will also affect the treatment effect due to inaccurate positioning. Ordinary puncture needle products generally adopt a beveled structure, so ordinary puncture needles have greater resistance when entering the human body, which is prone to problems with unsmooth needle insertion, reducing the convenience of the surgeon and the accuracy of the operation, and increasing the pain of the patient.

[0003] Therefore, the utility model proposes a drag-reducing ultrasonic puncture needle that can quickly determine the needle tip position to solve the above problem. Utility Model Content

[0004] The utility model aims to provide a drag-reducing ultrasonic puncture needle capable of quickly determining the needle tip position, so as to solve the problems raised in the above-mentioned background technology.

[0006] The enhanced air cavities can be arranged in a plurality of rings spaced along the outer needle tip, or can be arranged in a circle completely along the outer needle tip.

[0007] The micro pores are arc-shaped, circular or square in structure.

[0008] The outer side of the enhanced air cavity is covered with a heat shrink film.

[0009] The needle tip of the needle core is a conical structure, and a notch is provided at the needle tip.

[0010] A plurality of liquid medicine holes are arranged on the needle tip of the needle core.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0012] 1. The needle tip of the outer needle of the utility model is provided with an enhanced air cavity, and a plurality of tiny air holes are provided on the outer cavity wall of the enhanced air cavity, which enhances the presence of air in the air cavity, enhances the effect of ultrasound, makes ultrasound imaging clearer, ensures the positioning of the puncture needle, and provides a spiral line on the inner cavity wall of the enhanced air cavity, which can further enhance the effect of ultrasound reflection, making the positioning of the puncture needle more accurate, and avoiding the puncture needle from damaging nerves or accidentally injuring surrounding organs due to inaccurate positioning;

[0013] 2. The outer side of the enhanced air cavity of the utility model is coated with a heat shrink film, which can lock the air in the enhanced air cavity. This structural design can improve the recognition of the puncture needle during puncture under the guidance of ultrasound imaging, improve the accuracy of clinical puncture, and reduce the situation of repeated needle insertion due to unclear recognition;

[0014] 3. The needle tip of the needle core of the utility model is a conical structure, which can effectively reduce the force of the puncture needle when entering the human body, improve the convenience of the surgeon and the accuracy of the operation, reduce the pain of the patient, and speed up the efficiency of the operation. A notch is provided at the tip of the needle, which can facilitate drug administration or body fluid drainage and aspiration, and a plurality of drug solution holes are provided on the needle tip of the needle core, which further improves the efficiency of drug administration or body fluid drainage and aspiration, making the entire puncture more efficient.
