Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a combined pillow for puncture positioning and body position fixation in thoracic surgery. Background Art

[0002] Thoracentesis is a common diagnostic and therapeutic procedure in thoracic surgery, used for drainage of pleural effusions, pneumothorax decompression, obtaining pathological specimens, and surgical localization of small nodules. Its success depends on precise puncture positioning. Currently, clinical localization relies heavily on ultrasound or CT guidance, requiring patients to maintain a fixed position (such as sitting or lateral decubitus) for extended periods of time to ensure accurate positioning. Traditionally, patients are often manually supported by medical staff or temporarily supported by simple cushions or pillows. These traditional methods have significant drawbacks: 1. Poor postural stability: Patients can easily shift due to pain, fatigue, or respiratory movement, leading to misalignment of positioning markers and requiring repeated adjustments, which prolongs the procedure. 2. Heavy burden on medical staff: Patients require dedicated personnel to secure them, consuming human resources, and manual support is difficult to maintain consistently and accurately. Furthermore, CT-guided procedures generate electronic radiation. 3. Inadequate comfort: Conventional support materials cannot conform to the body's curves, potentially compressing nerves or interfering with breathing, increasing the patient's stress response.

[0003] Currently, some auxiliary tools have been used to try to improve the above problems. For example, a lung puncture fixation frame (patent number CN202510276667.2) uses a robotic arm to fix the body position and puncture needle, but the structure is complex, the cost is high, and it is inconvenient to disinfect; a multifunctional puncture bed (patent number CN201220169179.X) is a large device that is difficult to popularize for bedside operations and cannot be used for CT-guided operations.

[0004] In summary, existing tools still have shortcomings in terms of portability, cost-effectiveness, and precise adaptability. Therefore, there is an urgent need to develop a new combination pillow for thoracic surgery puncture positioning and fixation that meets the following requirements: 1. Precise fixation: Adapting to the anatomical structure to reduce positioning errors caused by body movement; 2. Convenient operation: Lightweight design, suitable for bedside or image-guided scenarios; 3. Improved comfort: Relieve patient pain and fatigue, and reduce operational risks.
