HongChuang Medical Devices (Changzhou) Co., Ltd. has officially received an invention patent granted by the China National Intellectual Property Administration (CNIPA) for its independently developed “Bipolar Vessel Sealing Surgical Instrument” (Patent No.: ZL 2025 1 0094520.1, Publication No.: CN 119745500 B). This milestone marks a significant step forward for HongChuang Medical in the field of high-end surgical energy devices, demonstrating the company’s unwavering commitment to achieving self-reliance in core minimally invasive surgical technologies.

Deep Expertise in Minimally Invasive Surgery, Solving the Core Challenge of Vessel Sealing

Bipolar vessel sealing instruments are indispensable in modern surgical procedures. They work by delivering high-frequency current between bipolar electrodes, generating thermal energy that denatures collagen and elastin in the vessel wall, thereby achieving coagulative sealing and precise hemostasis. As the global volume of minimally invasive surgeries continues to grow, the market demands ever-greater safety, versatility, and ease of use from vessel sealing devices.

However, core technologies and high-end products in this field have long been dominated by international medical device giants. The industry has been striving to overcome a key technical bottleneck: how to ensure reliable sealing performance while improving the instrument’s adaptability to vessels of varying calibers and reducing the complexity of surgical operation.

HongChuang Medical, driven by deep insight into clinical needs and a solid foundation of technical expertise, has chosen to differentiate itself by innovating at the level of instrument structural design — charting a distinctive path of independent innovation.

Ingenious Design: Switchable Dual-Head Electrode Architecture

The core innovation of this patented invention lies in its switchable dual-head electrode plate structure. The electrode plate features two ends of different sizes — one large and one small — which can be quickly switched by a 180-degree rotation. This allows surgeons to flexibly select the most appropriate clamping end based on the caliber of the vessel encountered during surgery, without the need to frequently change instruments.

This design delivers multiple clinical benefits:

Significantly Enhanced Adaptability: Surgeons can address vessels of different diameters without interrupting the surgical workflow to swap instruments, greatly reducing operative time.

Superior Tissue Protection: The fine end is designed for delicate small-vessel operations, preventing excessive clamping damage; the broad end ensures effective sealing of larger vessels. Both ends feature smooth, rounded surfaces to minimize mechanical trauma to vascular tissue.

More Efficient Electrode Contact: The electrode block surface incorporates linear protruding structures that increase the contact area with vessels, enabling more uniform current distribution and improved coagulation sealing performance.

Excellence in Detail: Multi-Dimensional Design Optimizations for Surgical Experience

Beyond the core switchable electrode design, this patent incorporates refined engineering across multiple dimensions:

Insulation Safety Design: The clamping blocks are made of insulating material to effectively prevent current leakage and ensure electrical safety throughout the procedure. The inner side of each clamping block features an arc-shaped groove that precisely mates with the conductive block, ensuring energy is accurately delivered to the target vessel.

Elastic Return Mechanism: A spring structure is positioned between the first and second handles, enabling rapid jaw opening upon release. This prevents prolonged clamping that could cause tissue damage while enhancing operational dexterity.

Adjustable-Angle Handle: The handle connects to the shaft via a rotational joint, allowing surgeons to freely adjust the handle angle based on the surgical site and personal preference — achieving a comfortable operating posture even within confined body cavities.

Locking & Pressure Relief System: By rotating the adjustment knob, surgeons can regulate spring pressure and lock the handle angle. This eliminates the need for continuous gripping during prolonged clamping, effectively reducing operator hand fatigue.

Building an Independent Innovation Portfolio with HongChuang at the Core

This invention patent is no accident. As an innovative medical device company rooted in Changzhou, HongChuang Medical has established independent R&D as its core growth engine since its founding, focusing on the technological advancement of electrosurgical and minimally invasive surgical instruments.

Today, HongChuang Medical has built a comprehensive patent portfolio spanning bipolar vessel sealing, electrosurgical tissue sealing, and multi-channel irrigation-suction control:

These three patents are mutually complementary, covering the complete surgical workflow from vessel sealing and tissue cutting to intraoperative irrigation and suction — reflecting HongChuang Medical’s systematic R&D strategy in the minimally invasive surgical instrument space.

Driving Domestic Substitution, Serving Clinical Needs

In the global bipolar vessel sealing system market, international corporations such as Johnson & Johnson and Medtronic have long held dominant positions. With the deepening implementation of China’s “Healthy China 2030” strategy and the increasingly clear policy direction toward self-reliance in high-end medical equipment, domestic medical device companies are seizing an unprecedented opportunity for growth.

HongChuang Medical will leverage this invention patent as a catalyst to further accelerate the commercialization of its core technologies. The company is committed to developing high-quality surgical instruments with independent intellectual property rights that meet the real-world needs of Chinese clinical practice, contributing to the rise of domestically produced high-end surgical instruments.
