However, the water circulation will take away a lot of heat during the ablation process, which requires increasing the ablation dose to achieve the expected thermal coagulation target volume. This undoubtedly increases the risk of carbonization.</p><p><strong>Methods: </strong>A design scheme of non-water-cooled microwave ablation needle based on double-layer vacuum structure was proposed. Two types of non-water-cooled microwave ablation needles with long and short needles were designed, and the ablation simulation was carried out by establishing the finite element simulation model.</p><p><strong>Results: </strong>Simulation and experimental results indicate that, at 20 W power, the long-needle vacuum tube ablation needle can create a carbonization-free solidification zone with a length of 34 mm after 180 s of ablation, whereas the short-needle vacuum tube ablation needle requires 300 s to form a similar zone with a length of 30 mm. Additionally, the axial ratio of the solidification zone created by the long-needle vacuum tube ablation needle exceeds that of the short-needle one. Consequently, the long-needle vacuum tube ablation needle is more apt for creating a larger solidification zone with minimal carbonization, while also achieving a more spherical shape.By comparing the ablation effects of long needle vacuum tube ablation needle and ky-2450b1 under low power,It is verified that the vacuum tube non-water-cooled ablation needle can ensure the effective ablation volume and non carbonization ablation under low-power and short-time ablation, which provides an important technical scheme for clinical optimization of the therapeutic effect of microwave ablation.</p><p><strong>Conclusions: </strong>The LPH-W-F-MWA is more adept at creating a larger coagulation zone with minimal carbonization, achieving a more spherical shape to a greater extent.

All surgical procedures were performed through a single 2.5 cm umbilical incision. An Intuitive Access Port of small size was placed into the incision, and pneumoperitoneum was established. Robotic instruments were inserted as described below through the Intuitive Access Port, which has four different channel ports: in the superior channel, a three-dimensional 8.5 mm optics; in channel 1, Cadiere Forceps; in channel 2, a Maryland Bipolar; and in channel 3, monopolar scissors.</p><p><strong>Results: </strong>From June 24 to November 13, 2024, a total of 25 patients were included in the study. The median age was 61 years, and median BMI was 25.9 kg/m<sup>2</sup>. The median docking time, console time, and total operative time were 10, 65, and 115 min, respectively. The median blood loss was 67.0 mL, and the median hemoglobin drop was 1.2 g/dL.</p><p><strong>Conclusions: </strong>R-SPH seems safe and feasible in endometrial cancer. The true benefit of the technique should be sought in larger comparative studies.
