FAQ

What are the design and ergonomic characteristics of urological surgical instruments?

The design and ergonomic characteristics of urological surgical instruments are mainly reflected in the following aspects:

The design of urological surgical instruments fully considers the principles of ergonomics to ensure that doctors can be more relaxed and comfortable during the operation. For example, the design of robotic equipment is more ergonomic, making the operator more relaxed during the operation.

Ergonomics studies the interaction between humans and machines and the design of the working environment, including the study of vision, hearing, touch and movement characteristics, in order to better design user-friendly products. This is particularly important in urological surgical instruments because doctors need to maintain high concentration and precise operation for a long time.

Designers must keep the operating force within the physiologically tolerable limit, so the biomechanical parameters and physiological characteristics of the human body must be measured and analyzed in detail. With these data, surgical instruments that are more suitable for doctors can be designed.

Weigao's "Miaoshou" robot innovates the multi-degree-of-freedom wire transmission decoupling design technology of minimally invasive surgical instruments, which is more conducive to maintaining accuracy and improving the movement flexibility and tissue processing capabilities of the instrument. This design not only improves the accuracy of the surgery, but also reduces the trauma to the patient.

In urological laparoscopic surgery, doctors use a master-slave control system for control, which makes the surgical process more accurate and efficient. For example, the single-port surgical robot of Jingfeng Medical adopts a multi-degree-of-freedom minimally invasive instrument design and has established a variety of solutions based on this platform technology.

The single-port laparoscopic surgical robot creatively designs dual-loop independent control hardware for full-state safety monitoring to ensure safety during the operation.

In summary, the design and ergonomic characteristics of urological surgical instruments mainly focus on ergonomic design, optimization of human-computer interaction, precise human body size measurement and application, multi-degree-of-freedom design of minimally invasive surgical instruments, application of master-slave control system, and safety monitoring and independent control hardware. The application of these design principles and technologies aims to improve the accuracy and safety of surgery, while reducing the labor intensity of doctors and improving the overall surgical experience.

What are the specific examples of ergonomic design in urological surgical instruments?

In urological surgical instruments, specific examples of ergonomic design include the following aspects:

Da Vinci surgical robot: This device has an ultra-clear 3D imaging system, 7 degrees of freedom and wrist-rotating surgical instruments, and meets ergonomic requirements. These designs not only improve the accuracy and perfection of surgical operations, but also make complex surgical steps such as suturing and reconstruction easier to complete.

Disposable puncture device: The disposable puncture device launched by United Micro-Invasive Company adopts a variety of different models and specifications of designs, which are original designs that meet various ergonomics. The set contains pneumoperitoneum needles, retrieval forceps, etc.

Surgical instruments with fully automatic continuous firing design: This design allows continuous firing without repetitive clip removal, improving surgical efficiency. Its handle can rotate 360 ​​degrees, which is convenient for precise placement and better surgical field of view. The three-axis universal joint is connected to the surgeon's wrist to restore the surgeon's wrist rotation angle.

High-frequency electrosurgical knife: The handle design of this device is ergonomic, which can reduce fatigue and stabilize operation, thereby reducing eschar and dryness on tissues and reducing tissue adhesion.

Laparoscopic surgical tool handles: Studies have shown that ergonomic instrument handles of different sizes are critical to surgical performance and surgeon ergonomics. The study tested four different sizes of ergonomic laparoscopic handle designs to analyze their impact on surgical execution time.

How to optimize the human-machine interaction of urological surgical instruments through ergonomics?

Optimizing the human-machine interaction of urological surgical instruments through ergonomics can be discussed in detail from the following aspects:

During urological surgery, doctors need to maintain a specific posture for a long time, which is prone to musculoskeletal diseases (WRMD). Therefore, designing ergonomic surgical equipment and stands is key. For example, the Condo robot supports doctors to perform surgery in an ergonomic posture, avoiding the stimulation and damage of the dark box high-brightness 3D to the operator's eyes, and reducing eye fatigue during surgery.

The layout of the operating room and the placement of equipment should be as ergonomic as possible. For example, the operating table of the Dexter laparoscopic surgical robot is optimized for use in both sitting and standing positions, and is covered in a sterile area and close to the patient, allowing surgeons to easily switch between the robot and the laparoscope.

During long surgeries, proper rest and stretching can effectively relieve muscle fatigue. By designing an operating table with adjustable height and angle, doctors can work in different postures and reduce muscle burden.

Intelligent human-computer interaction design can simplify user operations and improve surgical efficiency through automated functions. For example, the Tuo Ling laparoscopic surgical robot allows surgeons to be handy in delicate operations through automated functions such as one-button positioning.

The application of new equipment and technologies can significantly improve human-computer interaction. For example, based on Leap Motion's gesture control technology, using AR technology and Leap Motion devices, doctors do not need to touch surgical equipment during surgery. With the help of non-contact devices, doctors can completely stay away from the interference and risks caused by touch devices to surgery.

Lack of formal ergonomics education is a shortcoming in urology training programs. By emphasizing the teaching of ergonomic principles, doctors can better understand and apply these principles, thereby reducing the risk of work-related injuries.

How is the multi-degree-of-freedom design technology of minimally invasive surgical instruments achieved?

The multi-degree-of-freedom design technology of minimally invasive surgical instruments is mainly achieved in the following ways:

Wire transmission mechanism: A design of a six-degree-of-freedom wire-driven minimally invasive surgical instrument, including shoulder joint deflection freedom, elbow joint pitch freedom, wrist joint pitch freedom, rotation freedom, finger joint deflection freedom and finger opening and closing freedom. This design uses a wire transmission mechanism to fix the wire by the protrusion on the socket and the groove on the spring piece, and the two driving wheels are respectively connected to the socket to fix the wire, thereby achieving multiple degrees of freedom of movement.

Handheld multi-degree-of-freedom design: Two handheld multi-degree-of-freedom minimally invasive surgical instruments with high flexibility, easy operation, simple structure and low price are designed to improve the flexibility of surgical instruments.

Robot configuration: A small and compact redundant 7-DOF robot configuration is proposed, and a D-H kinematic analysis method is established for the surgical robot with a redundant 7-DOF serial structure.

Integrated design: The domestic surgical robot "Miaoshou" has made breakthroughs in the three key technical issues of multi-DOF wire transmission decoupling design of minimally invasive surgical machinery, reconfigurable layout principle and implementation of slave manipulators, and construction of system heterogeneous isomorphic control model, solving the technical difficulties of the robot set.

Super redundant DOF design: Design and modeling of super redundant DOF flying manipulator mechanism, and realize the prototype system of super redundant DOF autonomous operation flying manipulator.

High-precision multi-DOF surgical instruments: The patient surgical platform is equipped with an integrated robotic arm, high-precision multi-DOF surgical instruments, and the application of pleasant human-machine interaction interface and advanced intelligent control technologies enables the patient surgical platform to accurately follow the motion trajectory of the main controller.

How does the dual-loop independent control hardware of the single-port laparoscopic surgical robot work specifically?

The dual-loop independent control hardware of the single-port laparoscopic surgical robot works mainly in the following ways:

Application of high-precision servo motors: The system contains 68 high-precision servo motors, which are used for fully automatic preoperative positioning, intraoperative operation and master-slave control.

Dual-loop independent control hardware topology: This design creatively implements a dual-loop independent control hardware topology for full-state safety monitoring. This means that the system can monitor two independent control loops at the same time to ensure that the accuracy and safety of the operation can be maintained under any circumstances.

Low latency and high-frequency control: The full-link master-slave operation latency is less than 50 milliseconds, and 1,000 sub-millimeter surgical precision controls can be achieved per second. This shows that the system can perform a large number of precise operations in a very short time, ensuring the efficiency and accuracy of the operation.

Multi-level safety monitoring mechanism and emergency process control plan: The system integrates multi-level safety monitoring mechanism and emergency process control plan to ensure the safety of each stage of the operation. This design realizes full-state safety monitoring based on dual-loop independent hardware, and realizes full-time motion monitoring based on full-process risk warning.

How to ensure the effectiveness of safety monitoring and independent control hardware in the design of urological surgical instruments?

In the design of urological surgical instruments, ensuring the effectiveness of safety monitoring and independent control hardware needs to be considered and implemented from multiple aspects.

A specific safety integrity level (SIL) must be achieved, which requires not only controlling random failures of hardware, but also avoiding and controlling systematic failures of hardware and software. This means that during the design process, the hardware and software need to be fully evaluated and verified to ensure that they can meet the expected safety requirements.

In order to ensure that the hardware is suitable for the corresponding safety integrity level (ASIL), it must be proved that the hardware has sufficient safety mechanisms to detect and control random hardware failures, and the probability of failure must be proved to be low enough. This can be evaluated in two ways: hardware architecture metrics and hardware random failure probability metrics. These evaluation methods can help designers understand the performance of the hardware in actual use, so as to make corresponding adjustments and optimizations.

In addition, the use of an independent device management system can provide a centralized platform to manage and monitor all devices. This system usually includes hardware and software, and connects various devices through a network for management, thereby improving the availability and reliability of the system.

When designing a functional safety system, it is recommended to address functional safety compliance from the beginning of the design process. This means that when designing and delivering a functional safety system that meets the design budget, safety compliance and intended functionality need to be analyzed in tandem to avoid the problems that may arise from independent or sequential engineering.

Ensuring the effectiveness of safety monitoring and independent control hardware in the design of urological surgical instruments requires a comprehensive consideration of hardware and software reliability, the safety integrity level of the system, and the use of independent device management systems.
