Akso Microsurgical Teleoperation Robot

Akso represents Fuyee Medical’s core microsurgical robot platform, engineered to extend surgeon capabilities in procedures where human manual precision reaches its limits. The system targets head and neck microsurgery, particularly neurosurgical applications requiring sub-millimeter accuracy.

Product Overview

The Akso Microsurgical Teleoperation Robot System addresses fundamental limitations in manual microsurgery: natural hand tremor (approximately 100 microns), visual constraints in deep surgical fields, and physical fatigue during prolonged procedures. By translating surgeon movements through motion scaling and tremor filtration, Akso enables surgical maneuvers that exceed unassisted human capability.

The system adopts an anthropomorphic design philosophy, replicating the surgeon’s eyes, arms, and wrists through integrated robotic components. This approach differentiates Akso from conventional surgical robots that use serial kinematic chains without human-analogous architecture.

Key Features

Akso is a dual-arm teleoperated microsurgical robot by Fuyee Medical, featuring 2.5 mm instruments with tremor filtration capable of suturing vessels as small as 0.5 mm for head and neck procedures.

• Motion Scaling: Translates large surgeon hand movements into proportionally reduced instrument movements, enabling precise control in confined spaces
• Tremor Filtration: Eliminates natural hand tremor to achieve stability beyond human capability
• Dual-Arm Coordination: Two independently controlled robotic arms operate through a unified control system
• Micro-Instrument Articulation: 2.5mm instruments with wrist joints provide degrees of freedom comparable to human hands
• Integrated Visualization: High-magnification exoscope mounted on central arm provides optimal surgical field view
• Human-Robot Collaboration: Design preserves access for manual intervention during procedures

Technical Specifications

Akso is a dual-arm microsurgical robot by Fuyee Medical, using 2.5 mm pistol-shaped instruments with articulated wrists to suture vessels down to 0.5 mm in master-slave teleoperation mode.

Clinical Applications

Akso targets microsurgical procedures in the head and neck region:

Neurosurgery

• Tumor resection in confined cranial spaces
• Deep brain structure procedures
• Cerebrovascular interventions

Microvascular Surgery

• Vessel anastomosis (0.5mm and larger)
• Vascular reconstruction
• Free flap procedures

Nerve Surgery

• Peripheral nerve repair
• Nerve grafting
• Brachial plexus reconstruction

Lymphatic Surgery

• Lymphaticovenous anastomosis
• Lymphatic reconstruction for lymphedema

The pistol-shaped instrument design specifically addresses the challenge of operating through small surgical corridors. Traditional bulky robotic arms can obstruct access or limit depth penetration; Akso’s architecture allows instruments to reach deeper structures without compromising the surgical field.

Regulatory Status

Akso remains in research and development stages. The company conducts work through clinical collaboration centers to align development with actual surgical needs.

Frequently Asked Questions

What procedures can Akso perform?

Akso targets microsurgical procedures in the head and neck region including neurosurgery, microvascular anastomosis, nerve repair, and lymphatic surgery. The system is designed for procedures requiring precision beyond unassisted human capability, particularly suturing vessels as small as 0.5mm.

How does Akso differ from da Vinci surgical robots?

Akso focuses specifically on microsurgery with sub-millimeter precision requirements, while da Vinci targets general laparoscopic procedures. Akso uses smaller instruments (2.5mm vs 8mm), incorporates tremor filtration for microsurgical precision, and employs an anthropomorphic dual-arm architecture optimized for head and neck procedures.

When will Akso receive regulatory approval?

As of early 2026, Akso remains in development and has not entered the regulatory approval process. No timeline for NMPA submission has been publicly disclosed.
