Benefits of technology

This technology helps prevent cancer from spreading throughout your body by reducing its growth outside the area where it's supposedly happening or causing symptoms like pain for some people who have them surgery nearby. By doing this, they won’t develop new ones that could lead back into their own bodies again after treatment with radiation therapy.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving methods for treating cancers with high energy waves such as ultrasounds (high intensity sound wave) without causing harmful side effects on healthy tissues nearby. Current techniques involve injecting an agent called chloroquine inside the body near where the targeted area has been located beforehand, which helps prevent cell death caused by heat generated from laser treatment.

Embodiment 1

[0030] see Figures 1 to 9 , a microwave ablation device for protecting peritumoral tissue, comprising a cannula 1, an ablation needle 2, a cooling needle 3 and a handle 4, the ablation needle 2 is fixed on the handle 4, and the cannula 1 and the handle 4 can be The connection is disassembled, and several cooling needles 3 are evenly distributed around the cannula 1. There is a distance between the cooling needles 3 and the ablation needles 2. Several cooling needles 3 are used to surround the tumor. The needle 2 is located in the middle of the surrounding area surrounded by several cooling needles 3, and the cooling needle 3 is provided with a water inlet pipe 5 and a water outlet pipe 6, and the water inlet pipe 5 and the water outlet pipe 6 are at the end of the cooling needle 3 The positions are connected, the water inlet pipe 5 is connected to the external coolant supply device 7 , and the water outlet pipe 6 is connected to the external water tank 8 .

Embodiment 2

[0037] see Figures 1 to 11 , The difference between this embodiment and Embodiment 1 is that it also includes a number of injection needles 22, the injection needles 22 are evenly distributed around the casing 1, the injection needles 22 communicate with the infusion tube 23, and the infusion tube 23 communicates with injector 24. The injection needle 22 may or may not be fixed on the cannula 1 . Not fixed on the casing 1, the injection needles 22 are inserted into human tissues one by one during use. The inserted injection needle 22 surrounds the tumor tissue, and the syringe 24 communicates with the injection needle 22 through the infusion tube 23. Specifically, the injection needle 22 can communicate with the syringe 24 one by one through the injection tube 23, or the injection tube 23 includes a main pipe and a branch pipe, and the branch pipes are connected. On the main pipe, the main pipe communicates with the injector 24, and the branch pipes communicate with the inj...
