Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary skin patch device for transperineal prostate biopsy, which is particularly suitable for positioning, guidance and infection prevention in prostate biopsy procedures. Background Technology

[0002] Transperineal prostate biopsy is a commonly used clinical method for diagnosing prostate cancer, boasting a high positive rate and good safety profile. However, current techniques require repeated needle insertions to penetrate the skin and subcutaneous tissue. While transperineal prostate biopsy is often performed under local anesthesia, patients frequently experience pain. The primary cause of this pain is the repeated insertion and exit of the needle through the skin. Repeated punctures increase the risk of puncture-related complications, including hematoma and infection. To address this issue, a large-bore syringe needle is sometimes used clinically as a dermis to guide subsequent punctures.

[0003] However, due to the lack of effective fixation after puncture, the syringe needle will move with the puncture needle during subsequent punctures, or even dislodge. For example, a perineal prostate puncture dilator needle with announcement number CN209847244U is essentially no different from a syringe needle, and it still fails to effectively solve the problem of dilator needle movement during puncture.

[0004] In existing technologies, to address the aforementioned problems, the common practice is to secure the needle or syringe tip with medical tape after puncture. However, since medical tape and similar materials are flexible, careful attention must be paid to the application method when securing the needle or similar material. Otherwise, instability may occur. This requires a certain level of skill and experience from the operator, and the stability and reliability of the fixation vary from person to person. Utility Model Content

[0005] The purpose of this invention is to provide a transperineal prostate puncture guide needle kit to solve the technical problems in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A transperineal prostate puncture guide needle kit includes a puncture needle sheath, a needle hole with an inclined surface at the needle tip of the puncture needle sheath, a needle seat at the needle tail of the puncture needle sheath, a skin patch on the puncture needle sheath located at the bottom of the needle seat, and a skin patch pad on the inner surface of the skin patch.

[0008] The needle hub and the skin patch are connected by a connecting patch to increase the stability of the needle hub, and the skin patch is completely attached to the patient's skin to fix the puncture needle sheath.

[0009] Furthermore, the tip of the puncture needle sheath is frosted to facilitate visualization of the needle path under ultrasound.

[0010] Furthermore, the diameter of the skin patch is not less than 2.5cm, and an easy-tear strip is provided on the skin patch.

[0011] Furthermore, the puncture needle sheath is divided into two parts from top to bottom;

[0012] The upper part has a frustum structure that is thicker at the top and thinner at the bottom;

[0013] The lower part has a cylindrical structure;

[0014] The frosted part is located on the cylindrical structure.

[0015] Furthermore, a transition patch is provided at the connection between the skin patch and the puncture needle sheath.

[0016] Furthermore, a film layer is provided inside the needle hub.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] This invention reduces the number of punctures to the perineal skin by setting up a puncture needle sheath. At the same time, it improves the fixation structure of the puncture needle sheath, so that while ensuring the reliability of fixation, it can also prevent infection and provide a basis for enhanced ultrasound imaging, which facilitates the improvement of puncture quality. When fixing the puncture needle sheath, its integrated structure can be used for direct fixation, no longer relying on the operator's skills and experience, effectively ensuring the reliability and stability of fixation.

[0024] 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.

[0025] like Figure 1 and Figure 2 As shown, a transperineal prostate puncture guide needle kit includes a puncture needle sheath 1, a needle hole with an inclined surface is provided at the needle tip of the puncture needle sheath 1, and a needle seat 3 is provided at the needle tail of the puncture needle sheath 1. A skin patch 2 is covered on the puncture needle sheath 1 located at the bottom of the needle seat 3. The diameter of the skin patch 2 is not less than 2.5 cm and can be adhered to the patient's skin.

[0026] In this embodiment, the skin patch 2 is completely adhered to the patient's skin to firmly fix the puncture needle sheath 1 to the patient's skin. To facilitate the removal of the skin patch 2 after use, an easy-tear strip 5 is provided on the skin patch 2. The easy-tear strip 5 can be a non-adhesive portion and a raised adhesive strip on the edge of the skin patch, or it can be any other structure that is easy to tear off.

[0027] A skin patch 4 is provided on the inner surface of the skin patch 2, which can be peeled off and pasted onto the skin during puncture.

[0028] The puncture needle sheath 1 is divided into two parts from top to bottom;

[0029] The upper part has a frustum structure that is thicker at the top and thinner at the bottom. The upper part is 10mm long, with an outer diameter of 2.5mm at the top and an outer diameter of 1.6mm at the bottom.

[0030] The lower part has a cylindrical structure, with a length of 30mm, an outer diameter of 1.6cm, and a wall thickness of 0.1mm.

[0031] It should be noted that the entire puncture needle sheath 1 is inserted into the skin, leaving only the needle hub 3 on the skin surface to facilitate the insertion of the puncture needle.

[0032] Meanwhile, in order to facilitate ultrasound imaging, the tip of the puncture needle sheath 1 is sanded to improve the imaging effect of the needle tract under ultrasound. The specific location is the area with a cylindrical structure at the bottom in the above embodiment.

[0033] In the above embodiment, before puncture, a puncture needle sheath 1 is first inserted into the patient's prostate skin, and the puncture needle sheath 1 is inserted into the skin as a guide needle, leaving only the needle hub 3 outside for easy insertion. Essentially, the puncture needle sheath 1 forms an interventional channel for puncture. During actual puncture, there is no need to repeatedly puncture the perineal skin; multiple puncture operations can be completed simply through this interventional channel. This reduces the pain experienced by the patient during repeated punctures and effectively avoids the risk of infection associated with repeated punctures.

[0034] For infection prevention, a membrane layer can also be provided inside the needle hub 3, which can be directly passed through during actual puncture, providing conditions for aseptic operation.

[0035] In addition, the puncture needle sheath 1, with its frosted finish, enhances the display of ultrasound images, thereby revealing the needle path during interventional puncture and improving the accuracy of the procedure.

[0036] In this embodiment, the present invention differs from the prior art mainly in the following aspects:

[0037] First, the puncture needle sheath 1 is inserted into the patient's body, leaving only the needle hub 3. When it is fixed by the skin patch 2, its stability is relatively strong.

[0038] Second, the changes in the dimensional parameters of the needle hub 3 and the upper and lower parts of the puncture needle sheath 1 are beneficial for puncture;

[0039] Third, the skin patch 2 is directly fixed to the end of the puncture needle sheath 1. When using it, the protective film can be torn off and the patch can be applied. It does not rely on the operator's experience and skills to achieve quick and reliable fixation of the puncture needle sheath 1, effectively ensuring the reliability of the fixation quality.

[0040] In this invention, based on the aforementioned considerations of stability, the following two improvements are also included:

[0041] Firstly, the needle hub 3 and the skin patch 2 are connected by a connecting patch 6 to increase the stability of the needle hub 3;

[0042] Secondly, a transition patch 7 is provided at the connection between the skin patch 2 and the puncture needle sheath 1.

[0043] In the above, both the transition patch 7 and the connecting patch 6 enhance the connection between the skin patch 2, the needle hub 3 and the puncture needle sheath 1, and improve the stability of the connection.

[0044] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
