Operating table: "life-bearing platform" in surgical operations

In the sterile operating room of modern surgery, the operating table seems silent, but it carries the life safety of the patient and the precise implementation of the surgical operation, and can be called the "life-bearing platform" in surgery. From simple flat support to today's high-tech equipment with multi-functional adjustment and intelligent control, the development of the operating table has witnessed the continuous innovation of surgical technology. Every upgrade of its performance and function provides a more solid guarantee for the safety, efficiency and comfort of the operation.

1. Definition and basic structure

The operating table is the core component of the operating table, which is used to bear the patient's body and provide a stable and adjustable support plane for surgical operations. Its basic structure is mainly composed of the bed panel, adjustment mechanism, drive system and auxiliary devices.

The bed panel is the part that comes into direct contact with the patient's body. It is usually made up of multiple independent panels. These panels can be split, combined or adjusted individually according to surgical requirements to achieve different body position changes. Common bed panel partitions include headboard, backboard, seatboard and legboard. Each part can move independently or work together to meet the requirements of various surgical positions such as supine, lateral and prone positions.

The adjustment mechanism is the key to realize the various functions of the bed board, which is divided into two types: manual adjustment and electric adjustment. The manual adjustment mechanism mostly adopts mechanical structures such as gears, levers, hydraulic rods, etc., and the medical staff manually operate to complete the lifting, tilting, rotation and other actions of the bed board; the electric adjustment mechanism uses motors, controllers and transmission devices to realize the automatic adjustment of the bed board. Medical staff only need to use the operation panel or remote control to accurately control the position and angle of the bed board, which greatly improves the convenience and efficiency of operation.

The drive system provides power for the adjustment mechanism. Manually adjusted surgical bed boards rely on human power, while electric surgical bed boards are driven by motors, including DC motors, AC motors, etc., which work with transmission components such as transmission belts, lead screws and nuts to convert the rotational motion of the motor into linear or rotational motion of the bed board.

Auxiliary devices include various accessories and safety facilities, such as restraint belt fixing devices, infusion stand mounting interfaces, surgical instrument tray brackets, etc., which are used to ensure patient safety and facilitate surgical operations; in addition, they are also equipped with emergency brake devices, limit switches and other safety protection components to prevent accidental movement of the bed during adjustment, ensuring a safe and reliable surgical process.

2. Material selection and performance requirements

1. Material type

The material selection of the operating table needs to comprehensively consider multiple factors such as strength, corrosion resistance, biocompatibility, and radiotransmittance. Commonly used materials include metal materials, engineering plastics, and composite materials.

Among metal materials, stainless steel has become a common choice for surgical bed frames and support structures due to its high strength, corrosion resistance, and easy cleaning and disinfection. Aluminum alloy, with its advantages of light weight and high strength, is suitable for movable parts with strict weight requirements. Engineering plastics such as polycarbonate and ABS resin have good chemical stability, insulation and processing properties. They are often used as surface materials for bed panels, which can provide a comfortable touch and are easy to clean and disinfect. Composite materials such as carbon fiber reinforced composite materials combine high strength, light weight and good radiotransmittance. They are widely used in orthopedics, interventional surgery, and other surgeries that require intraoperative fluoroscopy. They can reduce the obstruction of X-rays and do not affect the image quality.

2.Performance requirements

High strength and stability: The surgical bed must be strong enough to withstand the patient's weight and various external forces generated during the operation to ensure that it does not deform or damage during the operation. At the same time, the structural design of the bed must ensure good stability, so that it can maintain balance even in extreme positions or when the patient moves, and avoid safety accidents such as rollover.

Corrosion resistance and easy cleaning: Since the surgical environment has extremely high requirements for sterility, the surgical bed must be able to withstand the erosion of various disinfectants, and the surface must be smooth and non-porous, easy to clean and disinfect, and prevent bacterial growth and cross infection. The corrosion resistance of the material can also extend the service life of the bed and reduce maintenance costs.

Biocompatibility: The bed board material that is in direct contact with the patient should have good biocompatibility and will not cause adverse reactions such as skin allergies and irritation, ensuring the patient's comfort and safety during the operation.

Radiotransmittance: In surgeries involving intraoperative fluoroscopy, CT guidance, or interventional therapy, the bed material must have good radiotransmittance to avoid interference with image quality, so that doctors can accurately observe the patient's internal conditions and perform precise operations.

3. Functional Features and Application Scenarios

1. Multifunctional body position adjustment

The core function of the operating table is to achieve diversified body position adjustment to meet the needs of different types of surgeries. For example, in cardiac surgery, the Trendelenburg position with the head high and the feet low is often used. By adjusting the angle of the back and seat of the operating table, the patient's body can be tilted, which is conducive to heart exposure and surgical operations; in neurosurgery, the prone position can be adjusted by adjusting the head board, back board and leg board to keep the patient in a comfortable and stable posture, which is convenient for doctors to perform brain surgery; and in orthopedic surgery, the angle and position of the bed board can be flexibly adjusted according to the fracture site and surgical method. For example, when reducing lower limb fractures, the traction and reduction functions can be achieved by adjusting the leg board.

2. Precise height adjustment

The electric operating table can achieve precise height adjustment, and the adjustment range is usually between 40-100 cm, which can meet the operating needs of medical staff of different heights and facilitate patients to get on and off the operating table. In some minimally invasive surgeries, precise height adjustment helps doctors find the best operating angle and operating position, improving the accuracy and efficiency of the operation.

3.Special function applications

Some high-end surgical tables also have special functions, such as C-arm compatible design, which facilitates X-ray fluoroscopy or angiography during surgery without the need to frequently move the patient, reducing surgical risks; intraoperative MRI compatibility function, which enables the surgical table to be used in magnetic resonance imaging equipment, providing convenience for neurosurgery, orthopedics and other surgeries that require real-time intraoperative imaging; in addition, there are surgical tables equipped with heating function, which can maintain the patient's body temperature during surgery, prevent hypothermia, and improve the patient's surgical safety.

4.Application scenarios

Surgical bed boards are widely used in various surgical operations, covering general surgery, orthopedics, neurosurgery, cardiothoracic surgery, obstetrics and gynecology and other departments. In general surgery, they are used for appendectomy, gastrointestinal surgery, etc.; in orthopedic surgery, they assist in fracture reduction, joint replacement and other operations; in neurosurgery, with its position adjustment function, it provides support for brain tumor resection, cerebrovascular surgery, etc.; in obstetrics and gynecology, it meets the position requirements of cesarean section, gynecological tumor resection and other operations. At the same time, in medical scenarios such as first aid and anesthesia, surgical bed boards also play an important role, such as quickly adjusting the position for cardiopulmonary resuscitation during first aid, and keeping the patient in a comfortable position during anesthesia.

5. Development Status and Future Trends

At present, surgical beds are developing towards intelligent, humanized, and multifunctional integration. In terms of intelligence, through integrated sensors and control systems, surgical beds can automatically identify the patient's weight and surgical position requirements, and intelligently adjust bed parameters; they can also be connected to other equipment in the operating room to achieve automated control of the surgical process, such as automatically adjusting the bed height and angle according to the anesthesia state.

Humanized design is reflected in paying more attention to the comfort and safety of patients. For example, an ergonomically designed bed surface is adopted to reduce pressure injuries during long-term surgery; cushioning materials such as memory foam and gel pads are added to improve patient comfort; and the operating interface is optimized to make operation more convenient and intuitive for medical staff.

With the trend of multifunctional integration, the surgical bed will integrate more functional modules, such as intraoperative monitoring equipment interfaces, energy equipment connection devices, etc., to achieve integrated integration of surgical equipment, reduce the complexity of equipment in the operating room, and improve surgical efficiency and safety. At the same time, with the development of 3D printing technology, customized surgical bed boards are expected to become a reality. According to the individual body shape and surgical needs of the patient, personalized bed board components can be printed to further improve the accuracy of the surgery and the comfort of the patient.

As an indispensable device in surgical operations, the continuous improvement of the performance and functions of the surgical table provides strong support for the development of modern surgical operations. With the continuous advancement of medical technology, the surgical table will play a more important role in ensuring patient safety and improving surgical quality, and promote surgical operations to be more precise, efficient and comfortable.
