FAQ
The design of micro-laparoscopic surgical instruments takes into account several factors to ensure their effectiveness and safety in surgery. Here are some of the main considerations:
Modular design: In order to adapt to different surgical needs, micro-laparoscopic surgical instruments adopt a modular design. For example, the ERAGONmodular concept is based on a 5 mm modular design and further developed into a 3.5 mm modular instrument that meets the top hygiene and application technology standards.
Reduced incisions: Micro-laparoscopic surgical instruments are designed to reduce the number of incisions required during surgery, thereby reducing trauma and postoperative scars.
Reduced bleeding: These instruments have good hemostasis and can effectively control bleeding during surgery.
Degrees of freedom and maneuverability: Traditional laparoscopic instruments usually have a straight axis and four degrees of freedom, which is not enough for the full rotation of the instrument tip. The new 7-degree-of-freedom instrument design can better access hard-to-reach organs in the abdomen and improve the precision and safety of surgery.
Human-machine interaction: In robotic surgery, workload is a key design factor. Micro instruments need to be able to achieve smaller incisions, more limited control over the surgical site, and be able to complete the operation quickly to help patients recover faster.
Anti-interference ability: For high-frequency surgical instruments, it is necessary to evaluate their anti-interference ability to the emission of high-frequency surgical equipment during design to ensure normal operation in the working state.
Safety and effectiveness: The safety and effectiveness of laparoscopic surgical systems in assisting doctors to perform surgery are confirmed through various methods such as model tests, animal tests and clinical trials.
The design of micro laparoscopic surgical instruments comprehensively considers multiple factors such as modularity, reduced incisions, reduced bleeding, degrees of freedom and operability, human-computer interaction, anti-interference ability and safety and effectiveness to ensure its efficiency and safety in actual surgery.
The specific implementation methods of the modular design of micro laparoscopic surgical instruments mainly include the following aspects:
Modular structure: Modular design allows surgical instruments to be combined and optimized according to different surgical needs. For example, the modular surgical robot developed by Ruilong Nuofu can set up different product combinations according to the clinical needs of the hospital, including a main console, different numbers of surgical arm trolleys, 3D laparoscopes, and instruments for performing surgical operations. This design makes surgical instruments more flexible and adaptable to various complex surgical operations.
Compatibility: Modular instruments are usually fully compatible with specific handles and can provide a variety of working lengths to adapt to different surgical scenarios. For example, the ERAGONmodular mini pediatric gripper is a modular instrument composed of three parts. Its slim diameter reduces surgical trauma at the port site, making it an ideal choice for mini laparoscopic surgery.
Intelligence and automation: Modern modular surgical instruments are not only optimized in physical structure, but also integrate intelligent and automated technologies. For example, the iqqa Polar Star Dragon Bird No. 1 intelligent modular laparoscopic surgical robot further assists doctors in performing various complex surgical operations through high-definition three-dimensional imaging systems, intelligent fusion technology, and flexible robotic arms. In addition, highly automated instruments can perform complex surgical steps, reduce the workload of doctors, and improve surgical efficiency.
Control system design: The control system of modular surgical instruments is usually developed using object-oriented technology and modular thinking, and the concept of flexibility and operability is used to establish a surgical planning and control platform. This design makes the operation of surgical instruments easier and more efficient.
The impact of modular design on surgical efficiency and safety is mainly reflected in the following aspects:
Improve surgical efficiency: Modular design allows surgical instruments to be quickly combined and adjusted according to specific surgical needs, reducing surgical preparation time and improving surgical efficiency. In addition, highly automated modular instruments can perform complex surgical steps, further improving surgical efficiency.
Reduce surgical trauma: The design of modular instruments usually considers reducing surgical trauma. For example, the slim diameter of the ERAGONmodular mini pediatric gripper reduces surgical trauma at the port site, thereby improving the patient's recovery effect.
Improve surgical safety: Modular design makes surgical instruments more flexible and precise, reducing the possibility of human operating errors, thereby improving surgical safety.
The technical details of micro-laparoscopic surgical instruments in reducing incisions mainly include the following aspects:
Use smaller lenses and instruments: Micro-laparoscopic surgery usually uses lenses and operating instruments with a diameter of only 3 mm or 5 mm, which can significantly reduce the surgical incision. For example, the use of a 5 mm micro-laparoscopic lens can reduce the "chopstick effect" and increase the operating space.
Single-port surgical approach: By reducing the main operating hole incision to 0.5 cm and adopting a single-port surgical approach, no suture is required, and no wireless knot remains in the incision, which effectively avoids complications such as puncture nodules and suture reactions. The postoperative pain is mild, the incision scar is subtle, and the cosmetic effect is very good.
Choose the right instrument: In order to cope with the problem of insufficient gripping force of micro-laparoscopic instruments, the market is developing micro-laparoscopic operating instruments with more stable performance and stronger gripping force to meet the needs of instruments with less micro-incisions.
Reduce operational interference: When performing micro-incision single-port surgery, the use of a 3 mm micro-lens and a 3 mm needle holder and operating forceps can free up the corresponding operating space and reduce mutual interference in operations.
Robotic-assisted surgery: The introduction of robotic-assisted surgical devices (such as MIRA™) can further expand the scope of minimally invasive surgery (MIS), providing greater precision and control, thereby reducing surgical incisions.
There are many ways to evaluate the hemostatic function and bleeding control ability of micro-laparoscopic surgical instruments, mainly including the following:
Platelet function test: Platelets play a key role in maintaining normal hemostasis. By testing the function of platelets, the effect of surgical instruments on platelet function can be evaluated. For example, a simple bedside test technique using a skin incision can be used to predict surgical bleeding. In addition, platelet function tests can also be used to diagnose platelet dysfunction in patients with long-term bleeding tendencies.
Thromboelastography (TEG): TEG is a laboratory test method used to evaluate the hemostatic properties of blood, identify coagulation disorders, and guide the transfusion of blood products. It can monitor the efficacy of antiplatelet drugs through different combinations of reagents.
Viscoelasticity testing: Viscoelasticity testing provides a real-time, holistic view of ex vivo coagulation, allowing examination of the contribution of cells and plasma proteins to coagulation, including platelet count and function, fibrin, etc.
In vitro coagulation test: For example, in vitro coagulation test of HNTs coating showed significant acceleration of coagulation process and reduction of blood loss.
Microstructure analysis of surgical hemostatic powder: The microstructure of commonly used surgical hemostatic powder can be observed by scanning electron microscopy and particle size test analysis to study its hemostatic performance.
Comprehensive value assessment index system: According to the patient's systemic factors (such as advanced age, obesity, comorbidities, etc.), doctors need to carry out stricter prevention and control of perioperative bleeding. The comprehensive value assessment index system and scoring reference standards can be used to comprehensively evaluate the effect of hemostatic materials.
The human-computer interaction design of micro-laparoscopic surgical instruments has the following innovations in improving operability and reducing surgical risks:
Non-contact interaction technology: Based on Leap Motion's interference-free interaction technology, non-contact operation is achieved through gesture recognition. This technology not only reduces the risk of surgical infection caused by contact interaction, but also increases the ease of operation for doctors.
Single-port surgical design: The single-port surgical system developed by Mira enters the body through a small incision on the navel and uses tools such as micro-laparoscopy, micro-graspers and micro-scissors for surgical operations. This design reduces surgical trauma, reduces costs, and shortens recovery time.
Hybrid human-computer interaction system: Using virtual reality technology and robotic arms, doctors can perform precise operations through the hybrid human-computer interaction system during surgery, and observe the internal structure through virtual reality technology, and provide real-time feedback on the surgical process. This system reduces the invasiveness to patients.
Intelligently designed surgical robots: Intelligently designed surgical robots can achieve precise surgical operations and reduce surgical risks and injuries. The application fields of this intelligent design are very wide, including medical care.
Research progress in the anti-interference ability of micro-laparoscopic surgical instruments is mainly concentrated in the following aspects:
Electromagnetic interference protection design: In order to ensure the normal operation of micro-laparoscopic surgical instruments in a high electromagnetic environment, the design and production of medical devices should ensure that the products have sufficient anti-electromagnetic interference capabilities. This includes measures such as electromagnetic shielding, filtering and grounding design to reduce the impact of external electromagnetic radiation on the equipment.
Charging function and anti-interference design: Some micro-laparoscopic surgical instruments have a charging function and anti-interference design, and can accept 3.0T field strength magnetic resonance imaging examinations. This design not only improves the flexibility of surgical instruments, but also enhances their stability in complex electromagnetic environments.
Optimized design of sealing chamber: For example, Mindray's disposable laparoscopic puncture device optimizes the design of the sealing chamber to maintain airtightness while avoiding interference between puncture devices and increase the depth of the instrument into the abdomen. This design helps to improve the accuracy and ease of operation of surgical instruments.
Passive design reduces interference: Some abdominal openers adopt a passive design and do not require external energy supply, thereby reducing interference and risks during surgery.
The research progress of micro-laparoscopic surgical instruments in terms of anti-interference ability is mainly reflected in electromagnetic interference protection design, charging function and anti-interference design, optimized design of sealing chamber and passive design.
