Precision in every pulse — Medichem’s intelligent vessel sealing technology.
Introduction
In today’s surgical environment, precision, safety, and consistency define success. Whether in open or laparoscopic procedures, reliable vessel sealing helps surgeons achieve rapid hemostasis with minimal thermal spread.
At Medichem Electronic, we’ve invested decades of R&D to design next-generation electrosurgical units that combine intelligent impedance monitoring with adaptive power control — ensuring every seal is strong, safe, and repeatable.
What Is a Vessel Sealing System?
A vessel sealing system is an advanced bipolar electrosurgical technology designed to permanently fuse blood vessels and tissue bundles.
Unlike standard cautery, which simply coagulates tissue, vessel sealing uses precisely controlled energy and pressure to denature collagen and elastin within the vessel walls, forming a permanent seal capable of withstanding high intraluminal pressures.
The Science Behind a Seal: Role of Impedance
During sealing, the tissue’s electrical impedance (resistance to current flow) changes dynamically as proteins denature and water evaporates.
- Initially, tissue impedance is low — current flows freely.
- As tissue dries and collagen fuses, impedance rises sharply.
- This rise is a natural signal that sealing is complete.
Modern systems, including Medichem’s, continuously monitor this impedance curve in real time. When a rapid increase in impedance is detected — indicating complete vessel fusion — the system automatically stops energy delivery and alerts the surgeon with a “Seal Complete” message or tone.
Why Impedance Matters
The impedance-based feedback algorithm acts like the “brain” of the system. It ensures:
- Optimal energy delivery: Prevents overheating or under-sealing.
- Reduced thermal spread: Protects surrounding tissue from collateral damage.
- Consistent seal quality: Every activation ends at the right moment.
- Shorter surgical time: Automatic termination simplifies workflow.
Medichem’s Innovation in Vessel Sealing
Our R&D team has optimized the impedance detection algorithm through extensive bench testing and tissue validation.
Each seal is correlated with burst pressure testing to ensure real-world reliability that meets or exceeds international standards.
Key Features:
- Dynamic impedance monitoring with multi-stage power control
- Adaptive feedback for various tissue sizes and hydration levels
- High seal strength (validated >350 mmHg in laboratory tests)
- Compatible with standard laparoscopic and open surgical instruments
