How CUHK’s Two-Arm Robot Could Make Digestive Tumour Removal More Precise
Two flexible arms could let an endoscopic surgeon lift tissue with one arm while dissecting beneath it with the other. The CUHK system is reported to be entering human trials, so its potential speed and precision are not yet established benefits for patients.

A new dual-arm endoscopic robot developed at the Chinese University of Hong Kong (CUHK) is designed to help surgeons remove early gastrointestinal tumours with greater control. Its two small, flexible instruments could work like a pair of hands: one lifts and steadies tissue while the other dissects beneath it. The system is entering human trials, so claims that it could halve procedure time remain a promise to test, not a proven result for this robot. 3

Why use two arms for endoscopic dissection?
Endoscopic submucosal dissection (ESD) removes a lesion by cutting through the tissue layer beneath the mucosa, the innermost lining of the digestive tract. In a difficult procedure, the surgeon needs a clear view of that cutting plane and a way to hold or retract tissue while dissecting.
A two-arm system is intended to provide that countertraction: one arm can lift or pull tissue, while the other performs the dissection. This bimanual approach can expose the submucosal plane and support precise cutting. 7
35 The robotic arms are reported to be 2.8 to 3.5 millimetres in diameter, with a separate camera providing the view.
7
The goal is not simply to cut faster. Better exposure and control may help surgeons remove a lesion while preserving the surrounding organ, but whether the new system achieves those benefits safely and consistently must be established in clinical testing. 3

What does the 49-minute figure mean?
A median robotic dissection time of 49 minutes was reported in a clinical study of 43 patients using the EndoMaster EASE system for colonic ESD. 39 That is a result from a different robotic platform; it should not be presented as the expected operating time for CUHK’s newer system.
The news report describes the CUHK robot as aiming to remove tumours in about half the usual time. 3 That is a potential benefit, not a demonstrated outcome for the system now entering human trials.
3
7 Procedure time can also depend on the lesion and the technique used, so the 49-minute result alone does not establish how much time the new robot might save.
Why a difficult polyp shows the potential need
In the case described in the report, Ho Man-wai had three polyps identified during a colonoscopy. Doctors removed two during the initial examination, while a more deeply rooted third required a more complex procedure. 3
The case illustrates why finding a polyp and removing it can pose different challenges. A lesion that is harder to access or dissect may require careful exposure and tissue control—the problem a second instrument arm is designed to address. 3
7 The account does not establish that Ho received robotic treatment or that the new robot would have been suitable for his polyp.
What needs to happen before wider use?
The reported next step for CUHK’s system is human trials. 3
7 Those trials will be important for establishing how safely and effectively it works in patients and whether its proposed advantages hold up in practice.
The available sources do not specify the system’s remaining trial requirements, approval pathway, cost or timeline for wider access in Hong Kong. Until those details and clinical results are available, the robot should be viewed as a promising technology under evaluation—not a routine treatment option.
