DETAILED DESCRIPTION

[0025] In thyroid surgery, the muscle traction device plays a vital role. It not only provides doctors with a clear surgical field of view, but also ensures the smooth progress of the operation and reduces surgical risks and complications. With the continuous advancement of medical technology, the muscle traction device for thyroid surgery is also constantly being updated and improved.

[0026] Overall structural design: Muscle traction devices used in thyroid surgery are usually composed of multiple components that work together to achieve the purpose of muscle traction and expansion of surgical field of view. The overall structural design usually includes a base plate, a traction component, a positioning component, an operating component, and other auxiliary components. The base plate is the supporting structure of the entire device and is usually designed to be a sturdy and easy-to-clean material. The base plate is provided with installation positions for various components to ensure the stability and ease of use of the entire device. The traction component is the key part to achieve muscle traction. It usually consists of a movable frame, a fixed frame, a traction rope, and an operating component. Movable frame: The movable frame is installed on one side of the patient's chin and is slidably connected to one end of the fixed frame. By pulling the traction rope, the movable frame can be moved away from the fixed frame, thereby achieving traction of the neck muscles. Fixed frame: The fixed frame is installed on one side of the patient's shoulder and fixed to the base plate. It works in conjunction with the movable frame to open the patient's chin and shoulders through the pulling force of the traction rope, thereby expanding the operable area of ​​the neck. Traction rope: A pulling component is provided at one end of the traction rope, and the other end is connected to the movable frame. By pulling the traction rope, the movable frame and the fixed frame can be moved away from each other, so as to achieve the traction effect on the neck muscles. The traction rope is usually designed to be soft and durable to ensure safety and reliability during the operation. Operating components: The operating components are used to control the tension and direction of the traction rope. It may include knobs, levers or other easy-to-operate mechanisms, so that the doctor can adjust the size and direction of the traction force as needed. The positioning assembly is used to ensure the stability and accuracy of the device during the operation. It usually includes a positioning frame and a clamping assembly. Positioning frame: The positioning frame is designed as a concave structure that can fit the shape of the patient's neck. It is provided with clamping assemblies at both ends to fix the device on the patient's body. Clamping assembly: The clamping assembly is usually designed with adjustable clamping force to ensure the stability of the device during the operation. They may include elastic clips, adjustable fastening straps or other easy-to-use fixing mechanisms.

[0027] In addition to the above main components, the muscle traction device for thyroid surgery may also include other auxiliary components, such as expanders, rotating rollers, cleaning tubes, etc. Expanders: The expanders are used to further expand the surgical field of view. It may include structures such as fixings, thin rods and through holes, through which the blood produced by the operation can be taken out to keep the surgical field clear. Rotating roller: The rotating roller is located under the patient's neck and is used to support the neck muscles. It may be designed with multiple raised points, and each raised point can be switched by rotation to put the patient's neck in a comfortable position. Cleaning tube: The cleaning tube is connected to the inside of the through hole and is used to clean the expander and the surgical area. This helps to reduce the risk of infection during surgery and ensure the smooth progress of the operation.

[0028] Key components and functions: Function of the traction component: The traction component is the core part of the muscle traction device for thyroid surgery. It achieves the purpose of traction of the neck muscles and expansion of the surgical field of view through the coordinated work of the movable frame and the fixed frame. Collaborative work of the movable frame and the fixed frame: The movable frame and the fixed frame are installed on the patient's chin and shoulder side respectively. Through the tension of the traction rope, the movable frame can be away from the fixed frame, thereby stretching the patient's chin and shoulders. This design not only expands the operable area of ​​the neck, but also provides doctors with a clearer surgical field of view. Adjustment of the tension of the traction rope: The tension of the traction rope can be adjusted through the operating component. The doctor can adjust the size and direction of the traction force according to the needs of the operation to ensure the optimization of the traction effect. Function of the positioning component: The positioning component is used to ensure the stability and accuracy of the device during the operation. It fixes the device on the patient through the coordinated work of the positioning frame and the clamping component. Fitting design of the positioning frame: The positioning frame is designed as a concave structure that can fit the shape of the patient's neck. This design not only improves the stability of the device, but also reduces discomfort during the operation. Adjustment function of clamping assembly: The clamping assembly is usually designed with adjustable clamping force. The doctor can adjust the clamping force according to the patient's body shape and surgical needs to ensure the firmness of the device during the operation. The expansion piece is used to further expand the surgical field of view and ensure the smooth progress of the operation. It usually includes structures such as a fixing piece, a thin rod and a through hole. The coordination of the fixing piece and the thin rod: The fixing piece is connected to the thin rod to form an expandable structure. By adjusting the position and angle of the thin rod, the surgical field of view can be further expanded. The connection between the through hole and the pipeline: The through hole extends into the inside of the fixing piece and is connected to the pipeline. Through the pipeline and the through hole, the blood generated by the operation can be taken out to keep the surgical field clear. Function of the rotating roller: The rotating roller is located below the patient's neck and is used to support the neck muscles. It may be designed to have multiple raised points, and each raised point can be switched by rotation to put the patient's neck in a comfortable position. Support function: The rotating roller reduces the burden on the neck muscles by providing support force. This helps to reduce discomfort during the operation and ensure the smooth progress of the operation. Adjustment function: The rotating roller is designed to have multiple raised points. The doctor can switch different raised points by turning the rotating roller to adapt to the patient's neck shape and surgical needs. Function of the cleaning tube: The cleaning tube is connected to the inside of the through hole and is used to clean the expansion piece and the surgical area. This helps to reduce the risk of infection during surgery and ensure the smooth progress of the operation. Cleaning function: The expansion piece and the surgical area can be cleaned by injecting cleaning fluid through the cleaning tube. This helps to remove contaminants such as blood and tissue fragments generated during surgery and reduce the risk of infection. Connecting design: The cleaning tube is connected to the inside of the through hole, ensuring that the cleaning fluid can flow smoothly into the expansion piece and the surgical area. This design improves the cleaning effect and ensures the smooth progress of the operation.

[0029] Technical features and innovation: With the continuous advancement of medical technology, muscle traction devices for thyroid surgery are gradually becoming automated and intelligent. For example, some devices have been equipped with drive mechanisms such as motors, which drive the rotation of the traction rope by electricity, thereby achieving precise control of the traction force. In addition, some devices are equipped with sensors and control systems that can monitor various parameters during the operation in real time and automatically adjust them as needed. In terms of materials, muscle traction devices for thyroid surgery have also made significant progress. Traditional metal and plastic materials are gradually replaced by softer, more durable and easier to clean materials. For example, the movable frame and fixed frame of some devices are made of polymer materials or composite materials, which have better elasticity and wear resistance; while the traction rope is made of high-strength, low-friction fiber materials to ensure safety and reliability during the operation. In terms of structure, muscle traction devices for thyroid surgery are also constantly innovating and improving. For example, some devices use adjustable movable frame and fixed frame designs, which can be precisely adjusted according to the patient's body shape and surgical needs; while other devices use detachable and reconfigurable designs, allowing the device to adapt to different types of operations and different surgical sites. Humanized design is also an important feature of muscle traction devices for thyroid surgery. For example, some devices have comfortable materials such as cushions or foam layers on the movable and fixed frames to reduce discomfort during surgery, while other devices are designed to be easy to operate and clean, making it easier for doctors to use and maintain the device.

[0030] The muscle traction device for thyroid surgery can significantly expand the surgical field of view, allowing doctors to see the surgical site and surrounding tissues more clearly. This not only improves the accuracy and safety of the surgery, but also reduces the operation time and the incidence of complications. Through the use of the muscle traction device, doctors can more easily pull away the tissue and expose the surgical site, thereby simplifying the surgical operation process. This helps to reduce trauma and bleeding during the operation, improve the success rate of the operation and the patient's recovery speed. The muscle traction device for thyroid surgery also focuses on improving patient comfort. For example, by using soft and comfortable materials and humanized design, the discomfort and pain during the operation are reduced; at the same time, by accurately controlling the traction force and direction, damage and compression to the patient's surrounding tissues are avoided. The use of the muscle traction device can also improve the doctor's work efficiency. Through automated and intelligent design, doctors can more conveniently control the traction force and direction, thereby saving operation time and labor costs. In addition, by reducing trauma and bleeding during the operation, doctors can complete the operation faster and reduce the incidence of complications, further improving work efficiency and patient satisfaction.

[0031] In the future, the muscle traction device for thyroid surgery will pay more attention to the development of intelligent control systems. By integrating more sensors and control systems, real-time monitoring and automatic adjustment of various parameters during the operation can be achieved, further improving the accuracy and safety of the operation. With the continuous advancement of materials science and technology, more advanced materials and technologies will be used in the muscle traction device for thyroid surgery in the future. For example, the main components of the device can be made of softer, more durable, and easier to clean materials; or more advanced manufacturing technology can be used to improve the accuracy and reliability of the device. In the future, the muscle traction device for thyroid surgery will also pay more attention to humanized design. By adopting more comfortable materials and structural designs, the discomfort and pain during the operation can be reduced; at the same time, by optimizing the operation process and interface design, the doctor's experience and satisfaction can be improved. With the continuous advancement of medical technology and the continuous improvement of people's health needs, the application field of muscle traction devices for thyroid surgery will continue to expand. In addition to traditional thyroid surgery, it can also be applied to other neck surgeries, such as lymph node dissection, laryngeal surgery, etc. In addition, with the development of telemedicine and robotic surgery technology, muscle traction devices may also be combined with these advanced technologies to provide more accurate and safer surgical treatment for more patients.

[0032] The muscle traction device for thyroid surgery is one of the key devices to ensure the smooth progress of the operation. It expands the surgical field of view by traction of the neck muscles and provides doctors with a clear surgical operation space. Existing devices have made significant progress in structural design, key component functions, technical features and innovations, providing a strong guarantee for the success of the operation.
