Abstract
Description
Technical Field
[0001] This invention relates to the field of medical hemostasis equipment technology, specifically to a semi-automatic puncture hemostasis device based on radiofrequency ablation and ultrasound positioning, which is an innovative product that integrates biomedical engineering, mechanical engineering and ultrasound detection technology. Background Technology
[0002] The battlefield environment is complex and harsh. Wounded soldiers often suffer from deep abdominal bleeding due to explosions, gunshot wounds, etc. This type of bleeding has a rapid onset and large volume. If rapid and precise puncture and hemostasis cannot be achieved, it can easily lead to hemorrhagic shock or even death. Therefore, efficient and precise battlefield first aid hemostasis equipment is crucial to reducing battlefield mortality. Currently, the commonly used hemostasis methods in battlefield first aid are mainly compression hemostasis and tourniquet hemostasis. These methods are only suitable for superficial bleeding and have limited effectiveness in stopping deep tissue bleeding. Furthermore, they cannot achieve precise location of the bleeding site or perform targeted puncture and hemostasis procedures.
[0003] With the development of medical technology, radiofrequency ablation hemostasis and ultrasound positioning technology have been gradually applied to the field of hemostasis, and related puncture hemostasis devices have begun to be used in emergency care. However, existing devices have many adaptability defects in their structural design, making it difficult to meet the special needs of battlefield emergency care. Most existing puncture hemostasis devices are manually operated, and the puncture accuracy depends entirely on the operator's experience. The structure lacks a stable guiding and driving mechanism, and the needle is prone to deviance during the puncture process, making it impossible to accurately reach deep bleeding sites. This not only affects the hemostasis effect but may also cause secondary tissue damage. The instability of manual operation is even more prominent in the noisy and vibrating environment of the battlefield.
[0004] In terms of structural layout, the puncture module and ultrasonic positioning module of existing devices are mostly designed separately, requiring operators to operate the positioning and puncture components separately. The operation process is cumbersome and the response speed is slow, which cannot meet the core requirements of "fast and efficient" battlefield first aid. At the same time, the separate structure increases the overall size and weight of the device, making it inconvenient for soldiers to carry. The connection parts are also prone to loosening, and may even fall off or malfunction during battlefield movement.
[0005] In addition, the protective shell structure of the existing device is poorly designed, mostly a regular rectangular structure, which is not ergonomic and makes it inconvenient for operators to hold in emergency situations. Moreover, the surface lacks anti-slip structure, making it easy for the device to fall off due to slippage. The drive mechanism mostly uses gear transmission, which is complex in structure, has a high failure rate, and the power transmission is not smooth enough, making it impossible to achieve precise and uniform advancement of the ablation needle, thus affecting the puncture and hemostasis effect.
[0006] In response to the unique challenges of battlefield first aid, existing puncture and hemostasis devices suffer from structural design flaws that prevent them from simultaneously achieving precision, speed, and portability, thus failing to meet the emergency treatment needs of soldiers experiencing deep abdominal bleeding in field conditions. Therefore, designing a compact, precise, easy-to-operate, and battlefield-enhanced semi-automatic puncture and hemostasis device, optimizing the structural layout of the puncture module, positioning module, and protective shell, and improving the device's stability and practicality have become pressing technical challenges in the field of battlefield first aid equipment. Summary of the Invention
[0007] The purpose of this invention is to provide a semi-automatic puncture hemostasis device to achieve the above-mentioned functions and objectives.
[0008] The embodiments of the present invention provide a semi-automatic puncture hemostasis device, which is based on the principles of radiofrequency ablation hemostasis, ultrasonic positioning, and innovative mechanism, combined with advanced manufacturing technology. It can achieve precise positioning, rapid puncture and efficient hemostasis of bleeding sites in soldiers under field conditions. The device is characterized by mainly including a semi-automatic puncture module, an ultrasonic probe module, a protective shell module, a connecting ring and a lamp tube.
[0009] The semi-automatic puncture module is assembled inside the protective shell module. The ultrasound probe module is connected to the protective shell module via a connecting ring. The lamps are installed on both sides of the front end of the semi-automatic puncture module.
[0010] Furthermore, the semi-automatic puncture module consists of a ball screw, screw nut, fixed bearing housing, sliding bearing housing, guide rods, ablation needle, servo motor, and motor bracket. The fixed end of the ball screw is assembled in the fixed bearing housing, and the movable end is assembled in the sliding bearing housing. The upper and lower surfaces of the fixed bearing housing are flat, while the left and right sides are curved. The upper surface of the sliding bearing housing is provided with a boss to support the ablation needle. Both types of bearing housings contain identical bearings and bearing retaining rings. Two guide rods pass parallel through the support base, fixed bearing housing, and sliding bearing housing to ensure the ablation needle is inserted. The ablation needle does not flip or deviate during linear motion. The lead screw nut is installed on the outer surface of the ball screw and forms a helical transmission engagement with the ball screw to convert the rotational motion of the servo motor into linear motion. The support base is installed on the outer surface of the lead screw nut, and the ablation needle is fixed on the support base. The motor bracket is installed on the upper and lower planes of the fixed bearing seat, and the servo motor is installed on the upper surface of the motor bracket. The fixed end of the ball screw is coaxially connected to the output shaft of the servo motor through a coupling to ensure the smoothness and coaxiality of power transmission, thereby achieving precise and controllable drive of the ablation needle.
[0011] Furthermore, the tail of the ablation needle is provided with two parallel annular grooves. These annular grooves are elastically assembled with the annular boss structure inside the support base by external force, thereby realizing the installation and fixation of the ablation needle and facilitating the quick assembly and disassembly of the ablation needle. Due to the small puncture force, the ablation needle will not fall off during the puncture process.
[0012] Furthermore, the ultrasound probe module consists of an ultrasound probe and a probe holder. The semi-automatic puncture module and the ultrasound probe module are integrated and arranged in a unified manner. The ultrasound probe and the ablation needle of the semi-automatic puncture module are arranged at a certain angle, with the needle tip of the ablation needle located above the ultrasound probe. The ultrasound probe has a preset tilt angle, the purpose of which is to make the detection area of the ultrasound probe intersect with the bleeding point in the patient's abdominal cavity and the needle tip of the ablation needle. With manual assistance, the ablation needle is pushed out to puncture the skin and soft tissue. Under real-time positioning by ultrasound imaging, the needle tip reaches the bleeding point. The high temperature generated at the end of the ablation needle is used to efficiently stop the bleeding.
[0013] Furthermore, the protective shell module consists of a protective shell, indicator lights, forward button, stop button, reverse button, and power switch. After the device is powered on, the operator presses the power switch, and the indicator light turns solid red, indicating that the device is in a power-on standby state. When the operator presses the forward button, stop button, and reverse button respectively, the ablation needle of the semi-automatic puncture module performs the corresponding forward, stop, and reverse actions, and the indicator light switches to solid green, indicating that the device is in working condition.
[0014] Furthermore, the protective shell module features an elliptical cross-section, conforming to ergonomic design for easy gripping by operators. Its outer surface is textured with anti-slip patterns to increase grip friction, effectively preventing the device from slipping when held by both hands. The rear of the protective shell is equipped with a pyramid-shaped wire connector, which is simple and aesthetically pleasing, while also facilitating wire connection and fixation, thus improving the stability of the wire connection.
[0015] Furthermore, the lamps are installed on both sides of the front end of the semi-automatic puncture module, and the color of the lamps is consistent with the color displayed by the indicator lights. Attached Figure Description
