Vessel Sealing and Cutting System: Advanced Electrosurgical & Vessel Sealing Technology
High-Performance Alternative to Harmonic Ligasure Devices for 7mm Vessel Ligation & Hemostatic Transection
The Vessel Sealing and Cutting System by Qianjing Medical is an intelligent advanced energy solution engineered for precise electrocoagulation, secure vessel sealing, and mechanical cutting during open and laparoscopic surgeries. Tailored to meet the clinical efficacy expected from premium harmonic ligasure devices, our electrothermal system reliably closes and transects vascular bundles up to 7 mm in diameter.
Compatible with modern high-frequency vascular closure systems, electrosurgical units, and comprehensive energy platforms, this system offers minimal lateral thermal spread and dependable hemostasis. It is the trusted choice for public general hospitals, surgical oncology centers, and international healthcare tenders seeking high-durability surgical energy equipment with superior clinical cost-effectiveness.
Harmonic Ligasure Device Machine in Surgery: Key Product Advantages
✔
Reliable 7 mm Vessel Occlusion: Capable of permanently sealing blood vessels and tissue bundles up to 7 mm in diameter in a single activation cycle.
✔
High Burst Pressure Resistance: The sealed vascular zone withstands more than 3 times normal human systolic pressure (exceeding 360 mmHg), ensuring superior post-op safety.
✔
Minimal Lateral Thermal Damage: Features precise energy confinement with transverse thermal damage restricted to <2 mm, protecting adjacent critical anatomical structures and nerves.
✔
Clear Visual Field & Fast Sealing: Rapid energy delivery produces minimal surgical smoke, maintaining optimal endoscopic clarity while eliminating foreign body implants (clips/sutures).
✔
Anti-Adhesion & Non-Carbonizing: Smooth jaw surface design prevents tissue adherence and eschar buildup, significantly decreasing blood loss, procedural duration, and patient hospitalization time.

Frequently Asked Questions (FAQ)
Q1: How does this vessel sealing system compare with harmonic ligasure devices?
A: While traditional ultrasonic harmonic scalpels excel in fine dissection and thin vessel transection up to 5mm, our advanced electrothermal vessel sealing and cutting system utilizes pulsed bipolar energy and optimized pressure feedback to reliably seal larger vessels and vascular bundles up to 7 mm with a burst pressure rating exceeding 360 mmHg. It provides the sealing security comparable to LigaSure technology with low smoke and minimal thermal spread.
Q2: Can the instruments be matched with third-party electrosurgical generators?
A: Yes. In addition to our dedicated SM5000 generator, our handpieces feature standardized connection cables that can be adapted to mainstream high-frequency generators and hospital surgical energy platforms, facilitating seamless integration for international hospital procurement.
Q3: Do you provide OEM/ODM and documentation for national tenders?
A: Qianjing Medical offers complete technical documentation, CE / ISO 13485 certifications, test verification reports, and customized OEM/ODM services to support regional distributors and public healthcare tender submissions.
