AI Technical Summary

Technical Problem

Existing stretching devices that fully expose the surgical field lack a waterproof layer design, which may cause the tape to peel off due to moisture, the hole to be torn by the bandage, and the bandage to go around the thigh and cause pressure injury.

Method used

It adopts a tape-combined stretching mechanism, including an upper clamp, a lower clamp and an elastic band, equipped with TPU medical composite cloth and silicone membrane, uses Velcro hooks and rubber guide blocks to enhance stability, and sets sliding pieces and polyurethane foam dressings to improve comfort. The clamps and fan-shaped pieces ensure fixation, and the elastic rope and silicone membrane provide waterproof and anti-penetration protection.

Benefits of technology

It effectively maintains a clear surgical field of view, reduces the risk of tape failure and pressure injuries, improves surgical efficiency and safety, reduces the risk of infection, and provides a stable and comfortable operating environment.
