以下是在前面介绍基础上，加入防止医生受 X 光辐射加长输送管相关内容的线控骨水泥输送系统介绍：
中文介绍
线控骨水泥输送系统是一种用于骨科手术中精确输送骨水泥的医疗器械装置。
- 结构组成：通常由控制器、输送管道、骨水泥储存器以及线控装置等部分构成。控制器是系统的核心部分，用于精确调节骨水泥的输送速度、压力和剂量。输送管道则是连接骨水泥储存器与手术部位的通道，一般采用特殊材料制成，具有良好的柔韧性和生物相容性，确保骨水泥能够顺畅地输送到指定位置。为了防止医生受到 X 光辐射，输送管通常会设计得较长，使医生能够在远离 X 光源的地方操作。骨水泥储存器用于存放骨水泥，其设计便于装填和密封，防止骨水泥泄漏和变质。线控装置则为医生提供了一种便捷的操作方式，通过控制线的牵拉或按压等动作，实现对骨水泥输送过程的实时控制，提高了操作的精准度和灵活性。
- 工作原理：该系统利用线控装置将医生的操作指令传递给控制器，控制器根据预设的参数和实际需求，精确控制骨水泥储存器内的压力变化，从而推动骨水泥通过输送管道输送到手术部位。在输送过程中，医生可以根据手术的实际情况，通过线控装置随时调整输送速度和剂量，确保骨水泥能够准确地填充到需要的部位，如骨折部位或椎体等，以达到固定、支撑和修复的目的。由于输送管的加长，医生可以在相对安全的距离外操作，减少了 X 光辐射的影响。
- 临床应用：主要应用于多种骨科手术，如椎体成形术、髋关节置换术、膝关节置换术等。在椎体成形术中，线控骨水泥输送系统可将骨水泥精确输送到压缩的椎体内，恢复椎体的高度和强度，缓解疼痛。在关节置换手术中，它能够将骨水泥均匀地填充到假体与骨组织之间，提供良好的固定效果，促进假体与骨的结合，提高手术的成功率和患者的康复效果。同时，在这些需要在 X 光透视引导下进行的手术中，加长的输送管能让医生远离辐射源，保障医生的健康。
- 优势特点：具有高度的精确性和可控性，能够实现骨水泥的微量、精准输送，减少骨水泥渗漏等并发症的发生。线控操作方便医生在手术过程中灵活调整输送参数，提高了手术的安全性和效率。此外，加长输送管的设计有助于减少医生在手术时受到的辐射伤害，而系统整体设计有助于提高骨水泥填充的均匀性和密实性，从而增强骨水泥的固定效果，有利于患者的术后恢复。
英文介绍
The line – controlled bone cement delivery system is a medical device used for the precise delivery of bone cement in orthopedic surgeries.
- Structural components: It usually consists of a controller, a delivery pipe, a bone cement reservoir, and a line – control device. The controller is the core part of the system, which is used to precisely adjust the delivery speed, pressure, and dosage of the bone cement. The delivery pipe serves as a channel connecting the bone cement reservoir and the surgical site. It is generally made of special materials with good flexibility and biocompatibility to ensure the smooth delivery of the bone cement to the designated position. To prevent doctors from being exposed to X – ray radiation, the delivery pipe is usually designed to be long, allowing doctors to operate away from the X – ray source. The bone cement reservoir is used to store the bone cement. Its design is convenient for loading and sealing to prevent the leakage and deterioration of the bone cement. The line – control device provides doctors with a convenient operation method. Through the pulling or pressing of the control line, the real – time control of the bone cement delivery process is achieved, which improves the accuracy and flexibility of the operation.
- Working principle: This system uses the line – control device to transmit the doctor’s operation instructions to the controller. The controller accurately controls the pressure change in the bone cement reservoir according to the preset parameters and actual needs, thereby pushing the bone cement to be delivered to the surgical site through the delivery pipe. During the delivery process, doctors can adjust the delivery speed and dosage at any time through the line – control device according to the actual situation of the operation, ensuring that the bone cement can be accurately filled into the required parts, such as the fracture site or the vertebral body, to achieve the purpose of fixation, support, and repair. Due to the lengthening of the delivery pipe, doctors can operate at a relatively safe distance, reducing the impact of X – ray radiation.
- Clinical applications: It is mainly used in a variety of orthopedic surgeries, such as vertebroplasty, hip replacement, and knee replacement. In vertebroplasty, the line – controlled bone cement delivery system can precisely deliver the bone cement into the compressed vertebral body to restore the height and strength of the vertebral body and relieve pain. In joint replacement surgeries, it can evenly fill the bone cement between the prosthesis and the bone tissue, providing a good fixation effect, promoting the combination of the prosthesis and the bone, and improving the success rate of the surgery and the patient’s rehabilitation effect. At the same time, in these surgeries that require X – ray fluoroscopy guidance, the lengthened delivery pipe allows doctors to stay away from the radiation source and protect the health of doctors.
- Advantages and characteristics: It has a high degree of accuracy and controllability, which can achieve the micro – and precise delivery of bone cement, reducing the occurrence of complications such as bone cement leakage. The line – control operation is convenient for doctors to flexibly adjust the delivery parameters during the operation, improving the safety and efficiency of the operation. In addition, the design of the lengthened delivery pipe helps to reduce the radiation damage to doctors during the operation, and the overall design of the system helps to improve the uniformity and compactness of bone cement filling, thereby enhancing the fixation effect of the bone cement and being beneficial to the patient’s postoperative recovery.
