This technology pertains to the field of medical devices and addresses the technical problem in existing technologies where surgical instruments have limited functionality, leading to cumbersome procedures and thereby compromising surgical outcomes.
In the current field of surgery, with advancements in laparoscopic technology and the advent of the da Vinci Surgical System, minimally invasive surgery has become the prevailing trend. Minimally invasive procedures cause less trauma to the patient’s body and facilitate postoperative recovery, thereby gaining increasing preference among patients.
Minimally invasive surgery has increasingly stringent requirements for surgical instruments. Numerous minimally invasive surgical devices related to electrical equipment are continuously being applied in surgeries, becoming one of the indispensable tools for laparoscopic procedures.
Currently, electrosurgical devices commonly used for tissue dissection in departments such as general surgery, urology, thoracic surgery, and gynecology include electrosurgical hooks, scissors, probes, spatulas, and needles. Most electrosurgical dissection devices lack intraoperative grasping capabilities, whereas hemostatic devices, primarily consisting of monopolar electrosurgical forceps and bipolar electrosurgical tweezers, offer certain grasping functions during surgery.
Due to the single-function nature of surgical instruments, it is necessary to replace them during surgery whether performing dissection or clamping procedures. This not only prolongs surgical and anesthesia time, increasing anesthesia-related risks, but also disrupts the continuity of the surgeon's operations, making the procedure more cumbersome and thereby adversely affecting surgical outcomes.
Therefore, based on practical experience in clinical settings, the team invented a laparoscopic multifunctional dissector to address the limitations of existing surgical instruments with single functions, which lead to cumbersome procedures and compromised surgical outcomes.
The core advantages of the patented technology for the "Laparoscopic Multifunctional Dissector" being commercialized in this instance lie inBy leveraging “integration of multi-functional operations + full-process safety protection” to build an integrated solution,Achieving technological innovation in both operational efficiency and surgical safety, thoroughly breaking through the limitations of traditional laparoscopic instruments characterized by "fragmented functionality, cumbersome operation, and inadequate safety assurance."
This technology pioneeredIn terms of functional integrationAchieved a disruptive breakthrough. It innovatively integratesSharp Dissection, Clamp Exposure, Electrocoagulation Hemostasis, Smoke SuctionThese four core functions are integrated into a single system, enabling the key maneuvers of laparoscopic surgery to be performed without the need for frequent instrument exchanges.
In conventional surgery, multiple instruments are required separately, including an electrocautery hook (for dissection), electrocautery forceps (for hemostasis), tissue forceps (for grasping), and a suction device (for smoke evacuation). This technology achieves functional integration by optimizing the instrument structure:
First, the inner surfaces of the forceps are equipped with conductive teeth that interface with the monopolar/bipolar electrocoagulation ports on the shaft. This design enables direct clamping of bleeding sites for precise hemostasis, while also allowing the grasping of gauze or tissue to expose the surgical field.
Secondly, the lateral surface of the forceps tip is equipped with sharp dissection attachments (with various options available, including dissecting hooks, electrocautery knives, and electrocautery spatulas). Through conductive configuration, sharp dissection can be performed intraoperatively to meet the surgical needs of different medical specialties.
Third, a suction tube is added between the forceps and the handle assembly, enabling continuous, close-range removal of smoke generated during surgery to prevent visual obstruction and ensure operational precision.
In the Field of Safety Protection Design, this technology has establishedMulti-layered Protection System, significantly reducing surgical risks.
First, when the clamp is in the closed position, all its exposed surfaces are coated with a primary insulating layer, ensuring that only the sharp dissection component and the clamp teeth remain conductive, thereby preventing accidental electrical burns during surgical procedures.
Second, the non-working portion of the sharp dissection component is encased in a second insulating layer, which further reduces the conductive area and enhances operational safety.
Third, the jaw features a curved design that adapts to the complex operative space within the abdominal cavity, facilitating deep access to the target area for dissection and grasping while minimizing the risk of accidental injury to surrounding tissues.
Furthermore, the deviceStructure in which the opening and closing of the forceps are controlled by wire pulling via a handle assembly, offering flexible and convenient operation that aligns with surgeons’ procedural habits, enabling physicians to quickly become proficient in its use.
In addition, this technologyIn terms of clinical adaptabilityPossessing“Multi-Scenario Compatibility + High Practicality”significant advantages.
In terms of scope of application,It can be widely used in laparoscopic surgeries across multiple departments, including general surgery, urology, thoracic surgery, and gynecology, accommodating diverse minimally invasive treatment needs.
In terms of structural design,The device’s structure complies with general laparoscopic operational standards and is compatible with standard trocar ports. The design of the sharp dissection component fully accounts for diverse tissue separation requirements, accommodating a wide range of surgical scenarios.
In terms of operational efficiency,The multifunctional integrated design reduces the frequency of instrument exchanges, shortens surgical and anesthesia time, and lowers patients' surgical risks. Meanwhile, it enhances the continuity of surgeons' operations, facilitating precise surgical execution.
Currently, in response to the core pain points of “single-function instruments, cumbersome operations, and high safety risks” in laparoscopic surgery, medical device companies both domestically and internationally have focused on“Multifunctional Integration, Enhanced Safety Protection, Ergonomic Design”Strategically structuring the R&D pipeline across three key areas to drive the upgrade of minimally invasive surgical instruments toward integration and precision through technological innovation, thereby meeting the clinical needs of multiple departments.
