Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to an ultrasonic imaging puncture needle with high ultrasonic reflectivity. Background Art

[0002] Puncture is a diagnostic and treatment technique in which a puncture needle is passed through the skin to reach the patient's lesion site, thereby forming a channel between the outside world and the lesion site, and performing biopsy sampling, radioactive particle implantation, cold or hot ablation treatment, etc., or injecting drugs into the lesion site. The purpose of puncture is to form a channel between the body surface and the lesion site, so that various minimally invasive interventional surgical techniques can be implemented, thereby achieving the goal of precise and targeted treatment.

[0003] The existing technology has the problem that the ultrasound imaging effect is poor due to the single structure of the puncture needle; in addition, the puncture needle has high requirements in medical supplies due to its contact with the internal tissues of the human body, requiring the cleanliness of the puncture needle and the ability to be stored in the external environment for a long time. Although the puncture needle itself is made of oxidation-resistant and corrosion-resistant materials, as a high-requirement medical consumable, the protection of the puncture needle still needs to be improved. Therefore, the utility model proposes a high-ultrasonic reflectivity ultrasound imaging puncture needle to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an ultrasonic imaging puncture needle with high ultrasonic reflectivity to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an ultrasonic imaging puncture needle with high ultrasonic reflectivity, comprising a matching needle core, a needle sheath and a needle cover, wherein the needle core is movably inserted into the needle sheath, the needle cover is detachably provided on the needle sheath, a plurality of needle core stabilizing rings are provided at intervals inside the needle sheath, and a plurality of reflecting parts are provided on the outer wall thereof, and a plurality of reinforcing stabilizing rings are provided at intervals inside the needle cover.

[0006] The needle sleeve is threadably mounted on the needle sheath.

[0007] The reflecting part is arranged between the needle core stabilizing rings, and the reflecting part is composed of a plurality of reflecting grooves.

[0008] The reflecting groove is an arc-shaped or semicircular structure.

[0009] The bottom end of the needle sleeve is a puncture-proof block structure.

[0010] The bottom of the needle sleeve is provided with a plurality of ventilation channels.

[0011] The ventilation channel is filled with dust-removing and moisture-absorbing cotton.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] 1. The utility model has multiple needle core stabilizing rings arranged at intervals in the needle sheath, which can ensure the stability of the needle core in the needle sheath, and ensure the accuracy of puncture. The outer wall of the needle sheath is provided with multiple reflecting parts, which enhance the ultrasonic reflection and improve the effect of ultrasonic imaging, so as to improve the accuracy of the puncture process. The reflecting parts are arranged between the needle core stabilizing rings, and gaps are formed between the needle core stabilizing rings. Air is retained in the gaps, which further enhances the reflection effect of ultrasonic waves on the basis of enhancing the ultrasonic reflection of the reflecting parts.

[0014] 2. The needle cover of the utility model is threadedly installed on the needle sheath. This installation method is convenient for removing the needle cover. The needle cover can effectively protect the puncture needle and prevent dust and water from falling on the needle sheath. A plurality of reinforcing stabilizing rings are arranged at intervals inside the needle cover to ensure the stability of the entire puncture needle and prevent the puncture needle from shaking in the needle cover. The bottom end of the needle cover is a puncture-proof block structure, which can enhance the effect of preventing the needle tip at the bottom of the needle sheath and prevent being stabbed by the needle tip at the bottom of the needle sheath;

[0015] 3. In the utility model, a plurality of ventilation channels are provided at the bottom of the needle cover. When the needle cover is installed on the needle sheath, ventilation inside and outside the needle cover can be ensured. The ventilation channels are filled with dust-removing and moisture-absorbing cotton to remove dust and moisture in the air. Ventilation can ensure the dryness of the entire puncture needle. Compared with the completely sealed puncture needle, this ventilation design is not only simple in structure and low in cost, but also has sufficient drying effect, so that the puncture needle can be stored in the external environment for a long time.
