Endoscopic End-Effector for Bone Surgery

Endoscopic End-Effector for Bone Surgery Using Fluid-Driven Burr Rotation

This technology is a multifunctional endoscopic end-effector mechanism that accesses lesion sites via a flexible insertion tube. It drives a hollow burr using fluid pressure and features an integrated channel within the burr for endoscopy, irrigation, and drug delivery.

Conventional orthopedic surgeries often require multiple incisions and the creation of large bone windows to access lesions, leading to risks of infection, excessive bleeding, restricted joint movement, and a heavy rehabilitation burden.

By combining a flexible insertion tube with a fluid-driven burr, this technology enables minimally invasive, single-port surgery. It also integrates multiple channels within the burr's axis of rotation for endoscopy, drug delivery, irrigation, and suction.

Key Features:

• An insertion tube that bends to reach the bone area requiring curettage, forming a path as it is inserted into the body.
• A burr unit mounted at the distal end of the insertion tube, designed to rotate and perform bone curettage.
• A burr coupling unit that mounts the burr at the distal end and rotates it using the pressure of fluid supplied through the insertion tube.
• A channel unit formed longitudinally to serve as the rotation axis for the burr, with an endoscope inserted into the channel.
