1. Industry and Clinical Pain Points

Standard universal brachytherapy needles have prominent limitations in the treatment of complex advanced malignant tumors, forming major clinical bottlenecks for personalized precise treatment. Most advanced tumors have irregular shapes, asymmetrical three-dimensional structures, and complex anatomical positions, often closely adjacent to vital organs, large blood vessels, and nerve plexuses. Fixed-size and fixed-structure standard needles cannot adapt to individualized lesion differences, resulting in unreasonable puncture trajectories and incomplete tumor radiation coverage. Second, complex tumors require multi-angle and multi-depth stereotactic seed implantation to achieve uniform three-dimensional dose distribution, but standard Mick needles have single parameter configuration, unable to match personalized surgical schemes, leading to uneven postoperative radiation dose and high tumor recurrence rate. Third, special surgical positions such as body cavity, apical, and concave lesions have strict requirements on needle body length, bevel angle, and tube diameter, while mass-produced standard products cannot meet special parameter needs, resulting in many complex cases unable to adopt minimally invasive brachytherapy and forced to choose high-risk open surgery. Fourth, standard single-configuration needles are prone to operational confusion in multi-needle combined implantation of large-area tumors, increasing intraoperative error risks. In addition, traditional manufacturers lack precise customized processing capabilities, with long proofing cycles and low precision, unable to meet emergency treatment needs of critical complex tumor patients.

2. Core Working Principles of Customized Application

Customized Mick type brachytherapy needles take complex tumor personalized treatment needs as the core, retaining all core functional advantages of standard products while realizing one-to-one adaptive optimization for individual lesions. The product inherits the classic dual structural advantages of sharp trocar obturator minimally invasive penetration and echo-enhanced beveled cannula visual positioning, and the hub cannula maintains professional honed ultra-smooth seed delivery performance. On this basis, targeted personalized adjustment is carried out according to clinical 2D/3D tumor anatomical drawings or sample parameters provided by medical institutions. Through flexible switching of industrial processes such as necking, swaging, laser cutting, laser marking, and electropolishing, customized optimization of core parameters including needle gauge, effective length, tube wall thickness, and bevel tip angle is realized. For complex stereotactic implantation needs, the needle body structure and angle can be personalized designed to match multi-angle three-dimensional puncture trajectories of irregular tumors. Customized appearance and structural configuration help doctors quickly distinguish needle specifications in multi-needle combined surgery, avoiding operational confusion. The overall customized design fully fits the individualized three-dimensional dose distribution plan of complex tumors, realizing precise and efficient personalized brachytherapy.

4. Standardized Customized Clinical Operation Guidelines

The clinical application of customized Mick brachytherapy needles follows personalized planning and standardized operation dual principles to ensure treatment safety and accuracy. First, preoperative personalized scheme design: collect patient tumor multi-modal imaging data, complete 3D lesion reconstruction, formulate targeted puncture trajectory, depth, and angle schemes, and put forward exclusive needle customization parameter requirements. Second, customized product parameter confirmation: communicate with manufacturers to verify the matching degree of customized size, structure, and functional parameters with clinical surgical schemes, and confirm product processing accuracy. Third, preoperative adaptive performance inspection: test the customized needle's trocar penetration performance, cannula seed delivery smoothness, and ultrasonic visualization effect to ensure compliance with personalized surgical needs. Fourth, targeted stereotactic puncture operation: adopt exclusive customized needles for corresponding complex lesion areas, complete multi-angle precise puncture according to preoperative 3D planning, and rely on visual positioning to adjust trajectory in real time. Fifth, zonal precise implantation: distinguish customized needles of different specifications, implement zonal seed implantation for irregular tumors, ensure uniform three-dimensional dose coverage, and avoid dose dead zones. Sixth, postoperative personalized efficacy evaluation: combine customized implantation parameters and postoperative imaging data to conduct refined efficacy assessment, providing basis for individualized follow-up treatment adjustment.

5. Practical Experience of Customized Clinical Application

Clinical practical application data verifies that customized Mick brachytherapy needles break through the scenario limitations of standard products and greatly expand the treatment scope of minimally invasive brachytherapy for complex malignant tumors. For advanced irregular tumors, deep hidden lesions, and tumors closely adjacent to vital organs that cannot be treated with standard needles, personalized customized Mick needles can perfectly fit complex anatomical structures, realizing precise minimally invasive implantation and reducing the open surgery rate of complex tumors by more than 45%. Personalized angle and size customization effectively solves the problems of dose dead zone and uneven dose distribution in complex tumor treatment, significantly improving the local control rate of advanced malignant tumors. Customized identification configuration completely avoids operational errors in multi-needle combined surgery, improving surgical efficiency and safety. The rapid customized processing capability can meet the emergency treatment needs of critical complex tumor patients, reduce surgical trauma and postoperative complications, and improve patients' quality of life and long-term survival benefit.
