AI Technical Summary

Technical Problem

Existing external thoracotomy devices lack integrated channels in cardiac surgery, requiring the introduction of additional gas perfusion and suction equipment, increasing operational complexity and affecting surgical efficiency. Furthermore, the lack of a closed exhaust system leads to blood splatter and aerosol exposure in the surgical field, endangering the health of medical staff.

Method used

Design a ventilable external chest opener that integrates an airway and uses an L-shaped instrument arm to achieve carbon dioxide perfusion and negative pressure suction. Combined with a three-way valve adjustment function, it provides a sealed connection and gas management, ensuring a clear surgical field and the safety of medical staff.

Benefits of technology

It effectively reduces the risk of air embolism in patients, reduces the concentration of smoke in the surgical field, protects the health of medical staff, and shortens the length of hospital stay for patients.
