FAQ

How does the size of laparoscopic surgical instruments affect surgical outcomes?

The size of laparoscopic surgical instruments has a significant impact on the surgical effect, which is mainly reflected in the following aspects:

Handle design and ergonomics: Handle size and design are critical to surgeon performance. Studies have shown that different sized handles can affect surgical performance time and wrist comfort, thereby affecting overall surgical efficiency and quality.

Flexibility and precision of instruments: Pliers should be able to open and close easily and flexibly without feeling stuck. When the forceps are closed, there must be no misalignment and the teeth of the forceps must be clear and complete, which are directly related to the accuracy and safety of the operation.

Trocar size: In laparoscopic surgery, Trocar placement is one of the primary issues. Due to the need for sufficient distance to focus and the slim size of surgical instruments, a certain distance from the surgical site is required. This requires that the size of the puncture device should be suitable for the surgical site to ensure the smooth progress of the operation.

Multifunctional integrated design: Some modern laparoscopic surgical instruments integrate multiple functions, such as grasping, traction, separation and electrocoagulation to stop bleeding. The realization of these functions often depends on the size and design of the instrument. For example, disposable bipolar electrocoagulation forceps can not only stop bleeding, but also reduce instrument replacement during surgery and improve surgical efficiency.

Adapt to different patient needs: For children or minimally invasive surgery patients with cosmetic requirements, using a small puncture device can reduce abdominal wall incision damage, shorten recovery time, and reduce pain and scars.

Compatibility and automation: Through modular, platform-based, and intelligent design, the modern laparoscopic surgical robot system can be compatible with traditional 5mm surgical instruments and robot-specific instruments, fully realizing the automated upgrade of laparoscopic surgery.

The size of laparoscopic surgical instruments affects surgical outcomes on multiple levels, including operating performance, precision, safety, multi-functional integration, adaptation to patient needs, and technology compatibility and automation. Therefore, when designing and selecting laparoscopic surgical instruments, these factors must be taken into consideration to ensure the best results of the surgery.

What are the latest research developments in laparoscopic surgical instrument handle design?

The latest research progress in laparoscopic surgical instrument handle design mainly focuses on the following aspects:

Intelligence and automation: With the development of artificial intelligence technology, laparoscopic surgical instrument handles are developing in a smarter and more automated direction. For example, Chengdu AI's research team analyzed about 2,000 laparoscopic cholecystectomy surgical videos through a big data platform, further improving the success rate of complex surgeries.

Remote operation capability: The application of 5G technology makes remote laparoscopic surgery possible, which not only improves the flexibility of surgery, but also expands the scope of surgery. The "5G Remote Laparoscopic Surgery Equipment Key Technology and Demonstration Application" project of the Affiliated Hospital of Qingdao University won the 2021 Qingdao Science and Technology Progress Award.

High-resolution imaging system: The innovative development of visual systems such as 3D laparoscopy, 4K or 6K high-definition imaging systems, and virtual reality provides clearer and more comprehensive image support for surgery, thereby improving surgical results.

Single-port laparoscopic surgery instruments: Single-port laparoscopic surgery has become a cutting-edge development direction in medical science and technology due to its advantages of less trauma, less postoperative pain, and shorter hospitalization time. Although there are currently few instruments and deficiencies in single-port laparoscopic surgery, researchers are working hard to overcome these problems to meet the requirements of minimally invasive surgery.

Robotic surgical system: The development of the first approved single-port endoscopic surgical robot in China marks a major breakthrough from imitation innovation to original innovation. The application of this robotic surgical system in laparoscopic surgery in urology has further promoted the development of minimally invasive surgical technology.

The latest research progress in the design of laparoscopic surgical instrument handles is mainly reflected in aspects such as intelligence, remote operation, high-resolution imaging systems, full-dimensional movement capabilities, and robotic surgical systems.

How to evaluate the impact of the flexibility and precision of laparoscopic surgical instruments on surgical outcomes?

To evaluate the impact of the flexibility and precision of laparoscopic surgical instruments on surgical results, detailed analysis can be conducted from the following aspects:

The flexibility of laparoscopic surgical instruments is one of its important features. Highly flexible surgical instruments can perform complex surgical movements in a small space, reduce surgical wounds and improve surgical safety. For example, a robotic surgical system has a multi-degree-of-freedom robotic arm that can perform complex surgical movements in a small space, thereby improving the flexibility of surgical control. In addition, the design of the snake-shaped surgical instrument allows it to bend freely and move flexibly, which is especially important for entering the body through a small incision for surgery.

Accuracy is another key metric for laparoscopic surgical instruments. High-precision surgical instruments can provide more precise control capabilities, reduce errors during surgery, and thus improve the success rate of surgery. For example, 3D high-definition electronic endoscopes and snake-shaped surgical instruments can achieve precise control of 1 mm, which greatly improves the accuracy of surgery. This high-precision control capability is extremely valuable in situations where fine tissue needs to be cut.

Evaluating the flexibility and accuracy of laparoscopic surgical instruments requires not only looking at a single indicator, but also needs to be combined with the actual surgical situation and the specific needs of the patient. For example, the three-dimensional visualization capabilities of robotic surgery platforms can help surgeons better understand complex anatomical structures, thereby improving the accuracy and safety of surgeries. Additionally, the use of an ergonomic surgical console can reduce surgeon fatigue and further improve the overall quality of surgery.

In actual operations, surgical instruments with high flexibility and precision can significantly improve surgical results. For example, research on single-port laparoscopic surgical instruments has shown that these instruments require more degrees of freedom throughout the surgical procedure to enhance their flexibility, which is of great significance for entering the body through a tiny incision. In addition, high-precision surgical instruments can reduce errors during surgery and reduce the risk of complications, thereby improving the success rate of surgery.

Evaluating the impact of laparoscopic instrument flexibility and precision on surgical outcomes requires a comprehensive consideration of multiple factors, including instrument design features, practical application performance, and patient-specific needs.

What are the best practices for trocar sizing in laparoscopic surgery?

During laparoscopic surgery, it is very important to select the appropriate size of the trocar to ensure smooth operation and patient safety. We can summarize the following best practices regarding trocar size:

Basic size setting: The basic inner diameter size of the trocar should not be too large to avoid difficulties when inserting surgical instruments within the cannula. For example, if a trocar has a nominal inner diameter of 5mm, its basic inner diameter size should be 5mm, not 5.1mm, as a slightly increased size would make smooth use inside the cannula difficult.

Children's trocars: For pediatric laparoscopic surgery, specially designed children's trocars should be selected, such as 3mm, 4mm and 5mm specifications. These sizes are smaller and more suitable for the surgical needs of pediatric patients.

Selection of size and length: The size and length of the trocar should be selected according to the surgical needs. Different surgeries may require different sized trocars, so the selection should be based on the type of surgery and the patient's condition.

Operation convenience: When choosing a trocar, its operation convenience should also be considered to ensure high efficiency and safety during the operation.

Avoid excessive force: When using the trocar, do not use excessive force. Once it has completely entered the abdominal or thoracic cavity, do not advance the trocar to avoid damaging intra-abdominal and thoracic structures.

Minimum aperture principle: In general, a channel with the smallest aperture that still allows for a safe surgical procedure should be used to minimize the risk of subsequent incisional hernia.

What are the design principles of multifunctional integrated laparoscopic surgical instruments and their specific impact on surgical efficiency?
The design principle of multifunctional integrated laparoscopic surgical instruments is mainly to improve the accuracy, reliability and intuitiveness of surgery, while reducing intraoperative instrument replacement and improving surgical efficiency. This design philosophy is reflected in multiple aspects:

Integrated multi-function: For example, adopts an integrated design, and all functions during the operation can be operated through the laparoscopic handle, so that you can switch between 2D and 3D at any time and achieve optimal intraoperative results. In addition, the disposable electrocoagulation cutter integrates the functions of grasping, pulling, separation and electrocoagulation to stop bleeding, which reduces the replacement of instruments during the operation, thus improving the efficiency of the operation.

Intelligent technology: The intelligent optical system can automatically track the movement of organs and tissues, and the intelligent handle can provide real-time feedback on the position and movement of the handle. These intelligent technologies have significantly improved the safety, efficiency and quality of surgery.

Multidisciplinary Applications: The ERAGON modular system sets the benchmark for quality and versatility for multidisciplinary use, assisting in a wide range of surgical applications, providing precise, reliable and intuitive operation.

The specific impacts are as follows:

Improve surgical efficiency: By integrating multiple functions and reducing instrument replacement, the surgical process is smoother, reducing surgical time and complexity. For example, the design of disposable electrocoagulation cutters significantly improves surgical efficiency.

Enhanced surgical precision: Intelligent technology and advanced image processing systems allow doctors to position and operate more accurately, reducing the risk of errors and complications.

Improve surgical quality: Integrated design and intelligent technology not only improve surgical efficiency, but also improve the overall quality of surgery, making surgical results more stable and reliable.

The design principle of multi-functional integrated laparoscopic surgical instruments significantly improves the efficiency, accuracy and quality of surgery by integrating multi-functional, intelligent technology and multi-disciplinary applications.

What are the latest technological advances in the compatibility of modern laparoscopic surgical robotic systems with traditional 5mm surgical instruments?

Significant technological progress has been made in the compatibility of modern laparoscopic surgical robotic systems with traditional 5mm surgical instruments. The German clinical-laparoscopic surgical robot Dexter is a typical example, equipped with an integrated robotic endoscope holder that is compatible with all 5mm and 10mm laparoscopes. This compatibility is not limited to the size of the scope, but also includes the scope arm being compatible with Dexter’s patient cart and can be controlled from the surgeon’s console.

In addition, domestic laparoscopic surgical robot systems are also constantly developing, gradually breaking the monopoly of original imported products in the high-end medical equipment market and injecting new vitality into market competition. These systems not only improve the flexibility and accuracy of surgery, but also provide a good platform for the application of remote control, artificial intelligence, augmented reality and other technologies in surgery.
