[0002] In laparoscopic surgery, patients often need to take a lateral position to fully expose the surgical field. At this time, the lateral position pillow as a key body position fixing device directly affects the operation efficiency and patient safety in terms of support stability and operational convenience.

[0003] Traditional lateral position pillows mainly achieve limiting support by setting clamping structures on the front and back of the patient's body. However, they rely on simple contact clamping and lack multiple fixed connections with the operating bed and the patient's body. Under the action of external forces such as tilting of the operating bed and operation pulling, the lateral position pillow is prone to displacement, leading to loss of control of the patient's body position and increasing the risk of insufficient exposure of the surgical field and obstruction of instrument operation. In addition, some existing technologies use fixing methods such as binding with straps or mechanical clamping. The straps need to be adjusted repeatedly for tightness, and long-term compression may cause skin damage to the patient. Mechanical clamps require position adjustment and fixation of the two clamps respectively, which is a tedious operation procedure. Especially in emergency surgery or rapid body position adjustment scenarios, it is difficult to meet the high efficiency requirements. SUMMARY
