Official Release of Achievements

We have systematically established a product design and development system for robotic surgical forceps jaws centered on clinical mechanical tasks. Going beyond simple classifications of graspers, scissors and dissectors, we have further subdivided specialized jaw configurations tailored to dozens of specific surgical maneuvers, including fine atraumatic grasping, powerful retraction, sharp dissection, blunt separation and precise electrocoagulation. Through innovative design, multiple functions (e.g., grasping + electrocoagulation, cutting + suction) are intelligently integrated into a single instrument tip, significantly reducing intraoperative instrument exchanges and improving surgical fluidity and efficiency.

R&D Background and Key Pain Points

In complex robotic surgeries, primary surgeons need to perform diverse tissue manipulations just as in open procedures. However, limited by the number of instrument channels, frequent tool changes disrupt surgical rhythm and prolong operation time.Conventional universal‑purpose jaws suffer from a jack‑of‑all‑trades‑master‑of‑none dilemma: insufficient grasping force causes tissue slippage; overly sharp serrations lead to tissue injury; poor dissection performance; and lack of effective hemostasis requires additional switching to electrocautery hooks or bipolar devices. Surgeons are forced to repeatedly switch between functionally limited instruments and cannot achieve seamless workflow where one instrument completes one surgical step. Clinically, there is an urgent demand for a series of specialized, multi‑functional jaws that precisely match the mechanical requirements of specific surgical actions and integrate key auxiliary functions.

Core Technological Innovations

Our innovation lies in clinical motion decoding and modular functional integration:

Task‑Oriented Subdivided Design

• Fine Atraumatic Graspers: Adopt wide, smooth spoon‑shaped or flat jaws with large contact areas and low pressure, suitable for grasping fragile tissues such as intestines and blood vessels. Micro‑dimples on surfaces enhance adhesion without puncturing tissue via sharp serrations.
• High‑Power Retraction/Grasping Forceps: High‑hardness interlaced coarse serrations embedded in jaws provide superior anti‑slip performance, used for retracting organs such as the uterus and stomach or tough fascial tissues.
• Sharp Dissecting Scissors: Ultra‑thin, sharp dual‑blade scissors with straight, curved or hooked cutting edges for precise tissue cutting. Some designs integrate micro‑electrodes to enable cutting with concurrent coagulation.
• Blunt Dissectors/Spreaders: Rounded or duck‑bill‑shaped jaw tips primarily used for blunt separation between tissue planes to expose surgical fields, rather than cutting.
• Multi‑Functional Integrated Design
• Bipolar Graspers: Insulated bipolar electrodes are integrated onto standard grasping jaws, enabling real‑time precise electrocoagulation for hemostasis while grasping tissue - achieving coagulation exactly where tissue is held.
• Irrigation‑Suction Integrated Dissectors: Independent micro‑channels inside instrument shafts connect to external irrigation and suction systems, allowing local irrigation and removal of oozing blood and smoke during tissue dissection to maintain clear surgical vision.
• Micro‑Blade Integrated Graspers: Retractable micro‑surgical blades are concealed within one side of the grasping jaws. After grasping and lifting tissue, blades extend for precise incision, suitable for procedures such as common bile duct incision.
• Ergonomic OptimizationFor long‑duration operations, we optimize the moment of inertia and weight distribution of jaws and instrument shafts. In collaboration with robotic system manufacturers, we refine algorithm matching for surgical‑field tremor filtering and motion scaling, enabling more natural and fatigue‑free transmission of surgeons' operational intent.

Mechanisms of Action

The core mechanism of specialization and functional integration is to reduce cognitive and operational loads of surgical manipulation while improving motion efficiency and safety.Through optimized jaw geometry, dimensions, serration patterns and material hardness, specialized designs deliver ideal mechanical effects when interacting with specific tissues: stable grasping with minimal pressure to prevent injury, efficient tissue separation to boost productivity, or controlled force transmission to ensure precision. Surgeons no longer need to strain to compensate for instrument limitations.Functional integration enables continuous motion workflows by physically combining related steps. For instance, the discrete conventional workflow of grasp‑release‑switch to coagulator‑locate target‑coagulate is transformed into the continuous action of grasp‑coagulate. This not only saves tens of seconds of instrument exchange time, but also avoids visual‑field loss and re‑positioning errors caused by tool switching, tightening surgical rhythm and shortening the decision‑execution loop.

Efficacy Verification

Clinical comparative studies show that in robotic radical prostatectomy, use of our wide‑surface atraumatic graspers for neurovascular bundle manipulation yields statistically significant improvements in postoperative urinary continence recovery time and erectile function preservation rate.In robotic gastrointestinal surgery, bipolar graspers with suction capability reduce average intraoperative instrument exchanges by 30% and shorten operation time by 15%.For our micro‑scissor integrated graspers, surgeons can complete gallbladder duct grasping, dissection and transection without instrument switching during cholecystectomy, receiving high praise for operational fluidity.Force‑sensing tests also confirm that specialized jaws require less operational force for their designed tasks, with smoother and more interpretable force‑feedback curves.

R&D Strategy and Philosophy

We uphold the design philosophy: From surgery, for surgery.Our R&D strategy establishes a clinical advisory committee mechanism for in‑depth collaboration with world‑leading robotic surgeons. We decode every surgical motion and clinical feedback from surgeons using engineering logic, translating them into designable and optimizable engineering parameters.Rather than pursuing universal‑purpose instruments, we commit to developing a portfolio of expert‑grade tools, enabling each jaw to excel in its dedicated application. We believe optimal instrument design allows surgeons to barely notice the tool intraoperatively, fully focusing on the surgery itself.

Future Outlook

Moving forward, we will explore adaptive instruments and automated surgical workflow modules. Research directions include developing jaw pressure adaptive feedback and control systems to prevent over‑grasping; designing AI‑enabled smart instruments that automatically identify tissue types and recommend or apply optimal grasping force and coagulation power; and developing macro‑command instruments that execute standardized combined actions (e.g., secure grasp‑dissection‑coagulation) with one click through deep integration with robotic surgical systems.Our ultimate goal is to evolve robotic surgical instruments into seamless, intelligent extensions of surgeons' cognition and physical capabilities, jointly ushering in a new era of surgery.
