Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an integrated microwave ablation therapy device. Background Technology

[0002] Microwave ablation therapy devices emit electromagnetic waves through a microwave generator (usually at a frequency of 915MHz or 2450MHz), which are then conducted to the tip of the ablation needle via a coaxial cable. This causes high-speed friction and heat generation of polar molecules (such as water molecules) within the tissue, with local temperatures reaching 60–150℃. When the temperature remains above 60℃, tumor cells undergo protein denaturation and DNA damage, resulting in irreversible coagulative necrosis. In current technologies, the temperature at the tip of the microwave ablation needle is high during treatment, which can easily lead to burns after removal. Furthermore, it is inconvenient to quickly cool down the ablation needle, making its safety less than ideal.

[0003] For example, patent publication number CN215503362U specifically describes a microwave ablation therapy device, relating to the field of microwave therapy device technology. It includes a main body with a groove on one side. A wire-forming mechanism is rotatably connected inside the groove. The wire-forming mechanism includes a connecting rod, and winding rods are symmetrically arranged on one side of the connecting rod. A semi-circular groove is formed on one side of the winding rod. This invention winds the connecting wire onto the symmetrically arranged winding rods. Because the winding rods have spaced semi-circular grooves, the connecting wire is wound in an orderly manner according to the intervals of the semi-circular grooves. After winding, a limiting strip is rotated to make it flush with the winding rod. Furthermore, the connecting wires are further secured by the magnetic attraction block adsorbing onto the side wall of the winding rod. The ablation needle is clipped into the hanging ring to prevent the connecting wires from becoming tangled and affecting the normal operation of the surgery. When using the treatment device, the rubber pad is close to the knee to prevent knee injury. The remaining connecting wires are inserted into the data cable sockets from both sides of the fixing block to prevent collisions and loosening that could affect the use of the device. However, there is a problem that the temperature of the needle tip is high during the treatment process, and burns can easily occur after removal. It is also inconvenient to quickly cool down the ablation needle, making the safety of use less than ideal. Utility Model Content
