The endoscope is a magnetic anchored, intelligent system that automatically tracks surgical instruments. A robot arm controls an external magnet above the patient’s chest. Inside the patient, an endoscope is guided by the magnetic force. The endoscope stays just beneath the chest wall, the observing the surgical scene from above. The robot controls the magnetic endoscope, guiding it to slide and rotate under the chest wall, providing various perspectives with the camera. An A.I. assisted instrument detection allows this system to track the surgeon’s tools. Surgeons can work intuitively without worries of endoscope control.
Problem to be solved (around 3 key points):
Conventional laparoscopes are poorly designed for single port surgery:
-
The long rigid body limits surgeon’s field of view.
-
It occupies much port space. Requiring bigger incision or additional port that traumatizes patients.
-
They collide with other instruments and interrupts surgeon’s workflow.
這磁錨定的智能內窺鏡, 具有自動追蹤手術工具的功能, 有效簡化手術和提高安全性。
系統裡的一個機械臂用以控制體外的磁鐵。一個透過磁力引導的內窺鏡會置於病人體內胸壁的位置, 從上而下地觀察手術場景。
機械臂控制磁內鏡在胸臂下移動, 提供多個視野。而人工智能則負責自動偵測和追蹤手術工具,醫生無需顧慮對內鏡的控制, 手術過程更方便安全。
針對問題 (約3個重點):
傳統的腹腔鏡設計並不適用於單孔手術:
-
長桿結構限制角度和視野
-
佔用端口空間, 需要更大或更多的創口, 增加創傷
-
容易和其他工具碰撞, 阻礙醫生工作流程
