1. What are Brachytherapy Needles?
Brachytherapy needles, also known as “radiation therapy needles” or “radiotherapy needles”, are a medical tool used for intracavitary treatment in radiation therapy, a method of treating cancer. It delivers a radioactive source directly to or near the tumor site. Brachytherapy needles are usually have two needles: Stylet and Cannula which work with each other to allow for targeted radiation therapy that destroys cancer cells while minimizing damage to surrounding healthy tissue. Matching with all kinds of hubs, the Brachytherapy needles produced in Manners Technology have the utmost quality and reliability, meeting the exacting demands of modern manufacturing.
2. Applications
Brachytherapy needles are widely used in cancer treatment, especially when treating solid tumors. These needles can be utilized to place radioactive sources precisely within or near tumor tissue to irradiate cancer cells, thereby destroying them. This helps minimize damage to surrounding normal tissue.
In actual surgical applications, they are very common in prostate cancer treatment. Doctors can use Brachytherapy needles to implant radioactive seeds into prostate tissue to precisely treat cancer without damaging surrounding tissue. And they can also be used to treat gynecological cancers, such as cervical cancer and endometrial cancer. They can be used to place radioactive sources at locations within or near the uterus to target cancer cells. Also, when treating eye tumors, these needles can be used to place a radioactive source or seed inside the eye tumor to irradiate the cancer cells.
In summary, Brachytherapy needles are an important tool for cancer treatment, which can be used across a variety of cancer types and stages of treatment. They enable precise, localized radiation therapy by placing the radiation source accurately in or near the tumor tissue, thereby helping patients get rid of cancer.
3. Categories
Brachytherapy needles usually consist of two needles: an inner needle called “Stylet” and an outer needle called “Cannula”, each of them serving different roles to achieve precise treatment. Among them, the stylet is a thinner needle used to pierce the tissue and locate the accurate position of the radioactive source, so that the Brachytherapy needle can achieve precise treatment. The Cannula is usually larger in diameter than the Stylet to accommodate the inner one and ensure it is in the correct position. It is usually hollow, that guides the Stylet to the target location while protecting the radioactive source or seed. This structure helps minimize damage to surrounding normal tissue while ensuring treatment accuracy. Different types and special designs of Brachytherapy needles are available in combination with Stylet and Cannula depending on specific treatment needs and cancer type. For example, there are designs with both tips sharp, and designs with a non-sharp stylet with a sharp cannula.
In addition, Brachytherapy needles often come with different types of handles to suit specific treatment needs and applications. Among these, the type Stylet Hub with the bevel-shaped tip has a handle that usually has a sharp tip for piercing tissue in order to accurately place the radiation source at the target site. While the type Cannula Hub usually has a handle with a hollow catheter that is used to guide and protect the accurate placement of the radioactive source or seed. The catheter can be of different diameters to accommodate different treatment needs. There is also an Afterloading Hub type, which is typically used for highly precise treatments in which the radioactive source is inserted inside the patient’s body and activated at the desired point in time. These needles are often used with computerized control systems for more precise treatment planning.
The different types of Brachytherapy needles and handles chosen depend on the doctor’s treatment plan and the location of the tumor, among other factors. Manners Technology specializes in customizing Brachytherapy needles with a variety of handles to meet ultra-high medical standards, and ensure the accuracy and effectiveness of the treatment.
4. Manufacturing
Manufacturing a Brachytherapy needle requires precise machining designs to ensure its accuracy and safety. Its Cannula usually needs to be very sharp to easily penetrate tissue, minimize tissue damage, and ensure precise positioning of the radioactive source. The Brachytherapy needle will adopt a sandblasted design and have a bevel-shaped echogenic needle tip to ensure its smooth and sharp shape. Manners Technology attaches great importance to the shape and sharpness of the needle tip and has exacting standards on the whole products.
The design of laser marking on the tube body makes it easier to see during ultrasound imaging or other imaging examinations, which helps doctors accurately locate and monitor the position and positioning target of the Brachytherapy needle in real time. Manners is machined using a 5-axis longitudinal lathe, and its internal sophisticated control system can precisely control the movement and intensity of the laser beam to create precise marks and patterns. The entire laser process is non-contact and does not damage the surface of the cannula so no impurities or defects are introduced.
Finally, quality inspectors assemble the individual components together and perform a full inspection to ensure that the needles function properly and meet quality control standards. This includes checking for sharpness, accuracy of development marks and ensuring there are no impurities or damage, no burrs and capes, etc. Manners Technology ensures that these processing steps and quality control measures ensure the safety, accuracy and effectiveness of Brachytherapy needles to minimize damage to surrounding tissue.
Manners Technology ensure that these processing steps and quality control measures are in place to guarantee the safety, accuracy and effectiveness of Brachytherapy needles. We always keep in mind that every aspect of our manufacturing process is crucial for the treatment outcomes of patients.
