Description

Technical Field

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

[0002] Microwave hemostasis technology is a new coagulation hemostasis method, which is applicable to the treatment of external trauma and trauma of deep parenchymal organs. When dealing with external trauma, in addition to applying traditional hemostasis measures such as physical compression and using hemostatic drugs, microwave hemostasis technology is also a very effective option. Especially for internal trauma and coagulation dysfunction cases where traditional hemostasis methods are difficult to implement quickly, certain progress has been made in new first-aid hemostasis technologies and hemostatic materials, and microwave hemostasis technology has received attention as a new coagulation hemostasis technology.

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

[0004] Since electromagnetic waves in the microwave band can cause polar molecules to vibrate and rotate to generate friction and heat, its characteristics are high efficiency, rapidity, and energy concentration; the principle of its hemostasis is to utilize the microwave biophysical effect to coagulate and inactivate the water-containing tissue at high temperature in an instant, so as to achieve the purpose of hemostasis at the bleeding site. The main advantages of microwave hemostasis technology include:

[0005] (1) Rapid blood coagulation: When microwave energy irradiates the blood at the wound, the blood will absorb the energy of the microwave, and the water in the blood will quickly evaporate, making the blood become viscous and coagulated, thus blocking the wound to achieve the purpose of rapid hemostasis.

[0006] (2) Infection prevention: The heat of the microwave has a bactericidal effect through the conversion of the instrument, which can prevent the wound from being infected by bacteria and is effective in preventing tetanus.

[0007] (3) Promote healing: Under the irradiation of the microwave, the speed of blood circulation can be increased, so it can provide sufficient nutrition for the wound and accelerate wound healing.

[0008] Under normal circumstances, microwave hemostasis surgery highly relies on an operating room environment that is well-equipped and has a stable power supply. Such operating rooms are not only equipped with advanced medical ultrasound diagnostic instruments but also configured with precise navigation systems and core devices - microwave generators and microwave hemostasis needles. However, in the face of emergencies or special situations, especially in the field environment, the above-mentioned complete operating room conditions are often difficult to meet, which greatly restricts the flexibility and applicability of the surgery, resulting in insufficient emergency response capabilities in emergencies, decreased resource allocation efficiency, limited technical popularization scope, and indirectly driving up medical costs.
