Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a double-helix tumor marker and implantation system. Background Technology

[0002] Cancer has become one of the most serious diseases threatening human life and health worldwide. With an aging population and changing lifestyles, the incidence of cancer is rising year by year. According to global cancer data released by the International Agency for Research on Cancer (IARC) of the World Health Organization, in 2020 alone, there were more than 19 million new cancer cases and nearly 10 million cancer deaths globally. Early diagnosis and effective treatment are crucial for improving the prognosis and survival rate of cancer patients. However, current cancer diagnosis and treatment face many challenges, especially in the early detection and localization of tumors, where more effective technologies and tools are urgently needed.

[0003] In recent years, the interdisciplinary integration of nanotechnology, materials science, and biomedical engineering has yielded numerous innovative achievements, bringing new opportunities for the development of novel tumor markers. Nanomaterials, due to their unique size, surface, and quantum size effects, exhibit excellent biocompatibility, high drug loading capacity, and modifiability, providing an ideal material basis for constructing novel tumor marker structures. For example, nanoparticles can serve as carriers to carry various functional molecules, such as fluorescent markers and therapeutic drugs, achieving the integration of tumor labeling and treatment. The rapid development of molecular biology techniques has enabled researchers to gain a deeper understanding of the molecular biological characteristics of tumor cells, allowing them to identify more tumor-specific targets and providing a theoretical basis for designing highly specific tumor markers.

[0004] While multidisciplinary technologies offer numerous possibilities for the development of novel tumor markers, effectively integrating the technological advantages of these different fields into the design and preparation of tumor markers remains a significant challenge. For example, when applying nanomaterials to tumor markers, issues such as the long-term safety, controllable release, and compatibility with the in vivo environment need to be addressed. When developing new marker targets using molecular biology techniques, it is crucial to ensure that the specific binding of the marker to the target is not interfered with by the complex in vivo biological environment, while also considering practical issues such as the simplicity of the marker preparation process and the controllability of costs. Against this backdrop, the development of novel tumor markers is urgently needed. The double-helix tumor marker was proposed precisely to meet this demand, and it is expected to overcome the limitations of traditional tumor markers, opening up new avenues for tumor diagnosis and treatment. Therefore, a double-helix tumor marker and implantation system are proposed to address the aforementioned problems. Utility Model Content

[0005] To overcome the above shortcomings, this invention provides a double-helix tumor marker and implantation system, which aims to improve the problem of tissue cutting caused by stress concentration in some existing devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A double-helix tumor marker includes a cylindrical body, the outer surface of which is provided with a double-helix thread in the same direction, and the two ends of the cylindrical body are symmetrically provided with round end structures.

[0008] As a further description of the above technical solution:

[0009] The double helical thread extends continuously along the axial direction of the main body and is evenly distributed circumferentially.

[0010] An implantation system for delivering a double-helix tumor marker, comprising a handle, a sliding connecting post slidably connected to the inner side of the handle, and a groove formed on the inner side of the handle;

[0011] As a further description of the above technical solution:

[0012] The handle is internally slidably connected to a sliding connecting block, and the bottom of the sliding connecting column is fixedly connected to a sliding push rod;

[0013] As a further description of the above technical solution:

[0014] The sliding push rod is slidably connected to a sheath, and the sheath is fixedly connected to the bottom of the handle.

[0015] As a further description of the above technical solution:

[0016] The sliding connecting block is externally fixedly connected to the outside of the sliding connecting column, and the sliding push rod is externally slidably connected to the inside of the handle.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, during tumor marking operations, a cylindrical main body is used to fix the position of the round-end structure. The advantages of the tumor marker include: flexibility, elasticity, large surface area, multiple steps, good contrast enhancement, and resistance to dispersion. The spherical ends prevent tissue damage, and the patient experiences minimal foreign body sensation. Because both ends of the cylindrical main body are round-end structures, the round ends are directly molded, soft, and elastic, deforming with human movement and tissue deformation, reducing foreign body sensation. The circumferential edges or ribs increase the contact area, and the steps provide fixation, reducing displacement. Firstly, the round-end structure, with its smooth transition surface, gently embeds into the predetermined position in the tissue, reducing hard punctures to surrounding tissues and lowering the risk of tissue damage. Secondly, during fixation, the stable mechanical properties of the cylindrical main body ensure the round-end structure remains firmly in place, preventing shaking or displacement. The electrolytically polished round-end structure effectively reduces surface friction with tissue, facilitating fixation, while also reducing protein adsorption and adverse reactions such as inflammation, providing a reliable and safe foundation for tumor marking.

[0019] 2. In this invention, when the marker is implanted into the human body, the doctor slides the sliding connecting block to facilitate the smooth sliding of the sliding connecting column within the handle, thereby driving the connected sliding push rod to slide within the sheath. The advantage of this design is that it allows the doctor to control the pushing speed and force. The sliding push rod smoothly pushes the cylindrical body at the bottom of the sheath into the human body, efficiently completing the marker delivery. The rounded end structure, the cylindrical body, and the unidirectional double helical thread are located at the bottom of the sliding push rod. The rounded end structure reduces the risk of tissue abrasion, the cylindrical body ensures structural stability, and the unidirectional double helical thread facilitates the fixation of the marker within the tissue, synergistically improving the implantation effect.

[0026] 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.

[0027] Example 1:

[0028] Reference Figures 1 to 2 This utility model provides an embodiment of a double-helix tumor marker, comprising a cylindrical body 1 as the core support structure of the entire tumor marker. The outer surface of the cylindrical body 1 is provided with a unidirectional double helix thread 2. The double-thread synergistic friction structure—the unidirectional double helix thread 2 design increases the contact area with superficial tissues, improves friction, and avoids stress concentration leading to tissue cutting. The two ends of the cylindrical body 1 are symmetrically provided with round end structures 3. The double helix thread 2 extends continuously along the axis of the body and is evenly distributed circumferentially. The round end structures 3 are directly formed, soft and elastic, and can deform with human movement and tissue deformation, reducing foreign body sensation. The symmetrical round end structures 3 at both ends of the cylindrical body 1 are designed to minimize the risk of scratching surrounding tissues such as blood vessels and nerves during implantation. The round end structures 3, the cylindrical body 1, and the unidirectional double helix thread 2 slide at the bottom of the sliding push rod 7. At the same time, the cylindrical body 1, the unidirectional double helix thread 2, and the round end structures 3 are at the bottom of the sheath 8, facilitating the sliding push rod 7 to deliver them and ensuring normal delivery.

[0029] Example 2:

[0030] Reference Figures 2 to 4An implantation system for delivering a double-helix tumor marker includes a handle 4, which is the operating part of the entire implantation system. The physician holds the handle 4 to control the entire implantation process. A sliding connecting post 5 is slidably connected to the inner side of the handle 4, serving to connect and transmit power. When the physician operates the handle 4, the sliding connecting post 5 slides within a groove on the inner side of the handle 4 according to the movement of the handle 4. A sliding connecting block 6 is slidably connected inside the handle 4, fixedly connected to the outside of the sliding connecting post 5, and slidably connected to the inside of the handle 4. A sliding ejector rod 7 is fixedly connected to the bottom of the sliding connecting post 5, and a sheath 8 is slidably connected to its outside. When the doctor pushes the sliding connecting column 5, the sliding push rod 7 will move forward accordingly. Its main function is to push the double helix tumor marker out of the sheath 8 to realize the implantation of the marker. The sheath 8 is slidably connected to the outside of the sliding push rod 7 and fixedly connected to the bottom of the handle 4. The inside provides a channel for the sliding push rod 7 and the double helix tumor marker. The sheath 8 is fixedly connected to the bottom of the handle 4. The sliding connecting block 6 is fixedly connected to the outside of the sliding connecting column 5. The sliding push rod 7 is slidably connected to the inside of the handle 4.

[0031] Working principle: When marking is required, the cylindrical body 1 fixes the position of the round end structure 3. At the same time, both ends of the cylindrical body 1 are round end structures 3. When the marker needs to be inserted into the human body, the sliding connecting block 6 slides the sliding connecting post 5 inside the handle 4, thereby driving the sliding push rod 7 to slide. The sliding push rod 7 slides inside the sheath 8, thereby pushing the cylindrical body 1 at the bottom of the sheath 8 into the human body. The sliding push rod 7 is used to push the cylindrical body 1 to facilitate the delivery of the marker. At the same time, the round end structure 3 and the cylindrical body 1 also have a double helical thread 2 in the same direction sliding at the bottom position of the sliding push rod 7.
