Description

Technical Field

[0001] The invention relates to the field of microwave ablation medical devices, and in particular to a miniaturized portable microwave hemostasis system. Background Art

[0002] Microwave hemostasis technology is an emerging coagulation hemostasis method, which is suitable for treating external trauma and deep solid organ trauma. In addition to the application of traditional hemostasis measures such as physical compression and the use of hemostatic drugs, microwave hemostasis technology is also an extremely effective choice when treating external trauma. Especially for those internal trauma and coagulation disorders that are difficult to quickly implement with traditional hemostasis methods, new emergency hemostasis technologies and hemostatic materials have made certain progress, among which microwave hemostasis technology has been valued as a new coagulation hemostasis technology.

[0003] Microwave hemostasis technology achieves coagulation hemostasis by inserting a microwave hemostasis needle into the bleeding tissue and using the microwave antenna at the needle tip to emit 2450 MHz microwave energy. This technology can be considered a minimally invasive surgery because it transmits microwave energy directly to the hemostasis area through puncture, thus avoiding traditional open surgery and reducing secondary damage to the human body.

[0004] Since the electromagnetic waves in the microwave band can make polar molecules vibrate and rotate to generate friction and heat, it is characterized by high efficiency, rapidity and concentrated energy; its principle of hemostasis is to use the biophysical effect of microwaves to make the water-containing tissue coagulate and inactivate at high temperature in an instant, so as to achieve the purpose of hemostasis at the bleeding site. The advantages of microwave hemostasis technology mainly include:

[0005] (1) Rapid coagulation: When microwave energy irradiates the blood at the wound, the blood absorbs the microwave energy and the water in the blood evaporates rapidly, making the blood viscous and coagulated, thereby blocking the wound and achieving the purpose of rapid hemostasis.

[0006] (2) Prevent infection: The heat from microwaves is converted by the instrument and has a bactericidal effect, which can protect the wound from bacterial infection and is effective in preventing tetanus.

[0007] (3) Promote healing: Under the irradiation of microwaves, the blood circulation rate can be increased, thereby providing sufficient nutrition to the wound and accelerating wound healing.

[0008] Under normal circumstances, microwave hemostasis surgery is highly dependent on an operating room environment with complete equipment and stable power supply. Such operating rooms are not only equipped with advanced medical ultrasound diagnostic equipment, but also equipped with a sophisticated navigation system and core equipment - microwave generators and microwave hemostasis needles. However, in the face of emergency or special situations, especially in field environments, the above-mentioned complete operating room conditions are often difficult to meet, which greatly limits the flexibility and applicability of the surgery, resulting in insufficient emergency response capabilities in emergency situations, reduced resource allocation efficiency, limited technology popularization, and indirectly pushing up medical costs.
