Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a puncture needle device for use in multiple scenarios. Background Technology

[0002] In the medical field, puncture needles (biopsy needles, insulated electrode injection needles) are used to collect a portion of human tissue or cells for definitive diagnosis of lesions or precise nerve localization. With advancements in medical technology, ultrasound-guided fine-needle aspiration biopsy has become increasingly common in routine medical practice in recent years. During PICC catheter placement, puncture is an essential step, establishing a connection between the body's blood vessels and the external environment to prepare for subsequent catheter insertion. Furthermore, existing puncture needles can only be used in a single scenario, requiring a separate needle for each application, increasing the cost of medical equipment and the inconvenience of changing devices. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a puncture needle device suitable for multiple scenarios, enabling the puncture needle to be applicable in various situations and avoiding frequent needle replacements in different usage scenarios. To achieve the above-mentioned objective and other advantages of this utility model, a puncture needle device suitable for multiple scenarios is provided, comprising: A puncture needle that is threadedly connected to a multi-functional replacement component; The multi-functional replacement component includes a base, a connecting groove is provided on the end face of the base near the puncture needle, and a first thread is provided on the inner surface of the connecting groove. A second thread is formed on the outer surface of the end of the base away from the puncture needle; One end of the puncture needle is an inclined needle tip, and a third thread is formed on the outer surface of the puncture needle near the end of the multi-functional replacement part.

[0004] Preferably, the puncture needle is hollow inside. Preferably, the base is hollow inside.

[0005] Preferably, the multi-functional replacement part can be directly connected to the multi-stage expansion sleeve through the hollow rear end by unscrewing the top nut. The multi-functional replacement part can be directly inserted into the disposable syringe by screwing in the top nut, or connected to the bone cement pressurizer through the external thread of the nut.

[0006] The advantages of this application compared to the prior art are: This puncture needle device can be used with various medical instruments such as multi-stage dilator sleeves, syringes, and bone cement pressurizers, meeting the needs of different scenarios and avoiding the need to replace multiple puncture needles, thus reducing the cost of medical devices. Furthermore, the puncture needle is detachable from the base, allowing for convenient cleaning and disinfection after each use scenario. Attached Figure Description

Detailed Description The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0008] Reference Figure 1 A puncture needle device for multiple applications, comprising: The puncture needle 2 is threadedly connected to the multi-functional replacement part 1; The multi-functional replacement part 1 includes a base, and a connecting groove is provided on the end face of the base near the puncture needle 2. A first thread is provided on the inner surface of the connecting groove. A second thread is provided on the outer surface of the end of the base away from the puncture needle 2; One end of the puncture needle 2 is an inclined needle tip, and a third thread is formed on the outer surface of the end of the puncture needle 2 near the multi-functional replacement component 1. When assembling the puncture needle device, the end of the puncture needle 2 with the second thread is screwed into the connecting groove, so that the puncture needle 2 and the multi-functional replacement component 1 are connected by threads. Furthermore, when the puncture needle device is used in a different scenario, the puncture needle 2 and the multi-functional replacement component 1 are disassembled for cleaning and disinfection, and then other medical devices are connected through the multi-functional replacement component 1, facilitating use in different scenarios.

[0009] Furthermore, the puncture needle 2 is hollow inside; the base is also hollow inside. This makes the puncture needle device suitable for both liquid injection and bone graft injection scenarios.

[0010] Furthermore, the multifunctional replacement part 1, with the rear end nut unscrewed, can be directly connected to the multi-stage expansion sleeve 3, the injection syringe with the rear end nut screwed in, and the bone cement pressurizer.

[0011] One embodiment, such as Figure 2 As shown, the puncture needle device can be inserted into the multi-stage expansion sleeve 3, which is hollow inside. It can be directly assembled with multi-stage expansion tools for use.

[0012] One embodiment, such as Figure 3 As shown, the nut at the top of the puncture needle device is unscrewed to guide the needle, which is then inserted into the multi-stage expansion sleeve 3, which is hollow inside. This allows for direct assembly and use with multi-stage expansion tools.

[0013] One embodiment, such as Figure 4 As shown, the base is connected to a syringe via a first thread. When anesthesia is required, puncture is performed through the puncture needle device, so that the puncture needle 2 reaches the site where anesthesia needs to be injected. The syringe is filled with anesthetic liquid, which is passed through the puncture needle 2 to reach the anesthesia site, thereby achieving nerve block during surgery.

[0014] One embodiment, such as Figure 5-6 As shown, the base is connected to a bone cement pressurizer via a first thread. In use, the puncture needle device reaches the location where bone cement needs to be injected through the puncture needle 2. When the puncture needle reaches the location, the bone cement pressurizer containing bone cement injects the bone cement into the desired site through the puncture needle 2.
