Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an implantation needle insertion auxiliary pusher. Background Technology

[0002] With the development of medical technology, radiotherapy has gradually become one of the important means of treating tumors, especially brachytherapy (afterloading therapy), which plays a vital role in the treatment of various tumors. Afterloading therapy is a type of localized radiotherapy that involves directly implanting a radiation source into the tumor or surrounding tissue. Compared with traditional external beam radiotherapy, afterloading therapy has higher dose concentration and better targeting, ensuring high-dose irradiation of the tumor tissue while minimizing radiation damage to surrounding healthy tissues. Therefore, afterloading therapy has been widely used in the treatment of various tumors, including breast cancer, cervical cancer, and prostate cancer.

[0003] However, during the implementation of afterloading therapy, the insertion of needles (such as...) Figure 1 As shown, needle insertion (consisting of a needle tube and a needle core with a needle core head, with the needle core being pulled out after insertion) has always been a technical challenge, especially when precise control of insertion position and depth is required. Traditional needle insertion usually requires medical personnel to manually push the needle core head, which not only demands a high level of technical skill and patience from the operator, but also easily leads to hand fatigue and pain during prolonged operation, affecting operational accuracy. In addition, uneven fixation and pushing force of the needle core head may lead to inaccurate needle insertion angle, thus affecting the treatment effect. Removing the needle core is also a difficult step; if the needle is unstable or the angle is incorrect, it may cause difficulty in removal or even damage the patient's tissues. Utility Model Content

[0006] Furthermore, the bottom rear side of the first groove is provided with a positioning slot for the head of the insertion needle core to extend into.

[0007] Furthermore, the ring has a finger hole in the middle for a finger to pass through.

[0008] Furthermore, the ring has an annular portion at the front, and the mounting rod is fixedly connected to the front end face of the annular portion. The annular portion also has several indicator grooves on its periphery.

[0013] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0014] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0015] like Figures 1-5 As shown, an implantation needle auxiliary pusher includes a finger ring 300 for wearing on a finger. The finger ring 300 has a forward-extending mounting rod 100 on its front side. The mounting rod 100 has a first groove 110 on its side for inserting the head 230 of an implantation needle 200. A second groove 120, penetrating the front end of the mounting rod 100, is provided on the front side of the first groove for inserting the needle tube. The width of the second groove is smaller than the diameter of the head of the implantation needle, so that the head of the needle is held in the first groove. In use, the finger ring 300 is worn on the finger, the head 230 of the implantation needle 200 is placed in the first groove 110, and the needle tube is placed in the second groove 120. The implantation needle 200 is inserted into place by pushing the pusher with the finger. Then, the pusher is pulled back to pull the head of the needle out. The first groove firmly holds the head of the needle, facilitating precise insertion and easy removal of the needle, avoiding operational difficulties caused by the needle getting stuck.

[0016] This auxiliary tool has a simple structure and small size, making it easy to insert needles.
