Surgical Robotics

Integrated Perioperative OMS Robotic System

A single platform spanning the full oral & maxillofacial surgery workflow — planning, registration, anaesthesia, robotic execution, and post-operative monitoring — with supervised and autonomous operating modes.

Four-arm oral and maxillofacial surgical robotic platform mounted on a single articulated base.

Plan — multimodal data (CBCT, MRI, intraoral & facial scans) builds a patient-specific anatomical model and surgical plan.
Overview

What it is

The system unifies the dispersed stages of oral & maxillofacial surgery — pre-operative planning, spatial registration and tracking, surgical-field preparation, anaesthesia management, robotic execution, intelligent perception, equipment & instrument management, and post-operative assessment — under one control module that coordinates data exchange, workflow switching, and safety interlocks.

It runs in two modes: a supervised mode, where the clinician confirms each critical step, and an autonomous mode, where the system executes validated workflows within embedded safety constraints while remaining open to immediate human takeover.

System Architecture

How it fits together

Nine functional modules share a single data layer and unified spatial coordinate frame. The control module sits at the centre, monitoring system state, patient state, and operational safety — and can trigger alarm, degrade, pause, terminate, e-stop, or hand control back to the surgeon.

How it works

The Operating Platform

Hardware

A purpose-built platform carries at least four arms — cutting, retraction, suction, and emergency — each with onboard lighting and imaging. Rail and ceiling-mounted variants, an embedded power rail, a dynamic counterweight, and end-effectors such as the force-sensing knife module and force-feedback retractor round out the system.

Single articulated surgical arm annotated with its joint rotation ranges (180 degree and 360 degree).
Fig. 6 · Articulated arm
Multi-joint arm with 180°/360° rotation at each axis for high reach and dexterity.
Ceiling-suspended ring platform carrying three downward-reaching surgical arms.
Fig. 4 · Ceiling-mounted variant
Suspended ring support frees floor space and approaches the field from above.
Rail-extended support structure with arms on a sliding track and a mobile support cart.
Fig. 5 · Rail-extended support
Embedded conductive rail powers sliding arm bases — no trailing cables — with anti-slip limit stops.
Knife module end-effector with an embedded scalpel and force sensor near the blade tip.
Fig. 7 · Force-sensing knife module
Senses tissue contact force at the blade tip to modulate depth, angle, and advance speed.
Soft-tissue retraction oral mirror with an elongated handle and a force-feedback detail at C.
Fig. 12 · Force-feedback soft-tissue retractor
Slender mirror handle with interchangeable tips and a force-feedback joint that limits retraction force to protect tissue.
