FAQ
In laparoscopic surgery, commonly used grasping tools include various types of grasping forceps and other related instruments. We can summarize the following main grasping tools:
Disposable fine-tooth grasping forceps: This type of grasping forceps is suitable for delicate tissue manipulation and can be used once, avoiding the risk of cross-infection and reducing the need for intraoperative instrument replacement.
Corrugated grasping forceps and blunt-tip grasping forceps: These grasping forceps are designed for specific surgical needs, such as corrugated grasping forceps may be suitable for tissues of specific shapes or textures, while blunt-tip grasping forceps may be used to avoid damage to surrounding tissues.
Gallbladder grasping forceps and mouse-type reverse-tooth grasping forceps: These specially designed grasping forceps are used to handle specific anatomical structures, such as the gallbladder or areas that require reverse teeth to operate.
Duckbill grasping forceps: This grasping forceps is shaped like a duckbill and may be used for specific minimally invasive operations or scenarios that require precise control.
Disposable abdominal wall stapler: This device is not only used for grasping, but also for the operation of sutures, especially in the suturing of abdominal wall incisions or puncture holes.
Bipolar electrodes (separation forceps, grasping forceps): This device integrates functions such as grasping, pulling, separation and electrocoagulation hemostasis, and is suitable for surgical scenarios that require multiple operations at the same time.
Intelligent grasper: This advanced device provides real-time force feedback to help surgeons control grasping force more accurately, thereby improving surgical results and reducing learning curves.
The choice of these tools depends on the specific needs of the surgery, including the type of operation required, the characteristics of the tissue, and the expected surgical results. Each tool has its own unique design and function to meet different surgical scenarios and needs.
The specific application scenarios and advantages of disposable fine-tooth grasping forceps in laparoscopic surgery are as follows:
Application scenarios
Disposable fine-tooth grasping forceps are mainly used for the treatment of diseased tissues in laparoscopic surgery. Because most diseased tissues are adhesive, traditional grasping forceps can only grasp and pull out the diseased tissue, but cannot shear it, which is inconvenient in actual operation. Therefore, disposable fine-tooth grasping forceps can effectively solve this problem and provide a more convenient operation method.
Advantages
Reduce the risk of cross infection: Due to the one-time use, repeated disinfection and cleaning can be avoided, thereby reducing the risk of cross infection.
Improve surgical efficiency: The fine tooth design can better grasp and pull the diseased tissue, reducing the operation time during the operation.
Protect the field of vision in the surgical area: Well-designed auxiliary grasping forceps are helpful for suturing and knotting in the body. Its curved tip is conducive to winding the coil when knotting in the body, and will not hinder the field of vision in the surgical area.
Strong adaptability: The large jaw size provides stronger adaptability, enabling it to cope with lesions of different sizes and shapes.
Relieve surgical fatigue: The design with locking card helps to reduce manual fatigue during surgery and improve the comfort of surgery.
The specific shapes or textures of tissues processed by corrugated grasping forceps in laparoscopic surgery mainly include the following points:
Non-damage design: The design of the corrugated grasping forceps focuses on non-damage, and the special forceps head hardness (330~420hv0.2) is used to ensure that the requirements of non-damage are met when grasping tissues and organs.
Anti-adhesion coating: In order to reduce tissue adhesion, the material of the bellows grasping forceps is specially treated to form an innovative anti-adhesion coating, which helps to improve surgical efficiency while maintaining safety and reliability.
Corrugated design: The corrugations of the clamp head along the tissue engagement surface 105 of the bellows grasping forceps can vary, for example, the amplitude increases toward the distal tip, thereby reducing the possibility of the clamp sliding off the clamped tissue. This design helps to better control and fix the tissue.
Material selection: The head of the bellows grasping forceps is made of 0Cr17Ni4Cu4Nb, the rod is made of 1Cr18Ni9Ti, and the outer tube of the rod is made of high-performance materials such as PEEK. The selection of these materials helps to improve the durability and operating performance of the grasping forceps.
The specific use cases and effect evaluation of gallbladder grasping forceps and mouse-type inverted tooth grasping forceps in gallbladder surgery are as follows:
Gallbladder grasping forceps:
Application case: In transumbilical single-port laparoscopic cholecystectomy, Minilap grasping forceps can fully expose the gallbladder due to its high hardness, large opening and strong grasping force, thereby shortening the operation time. In addition, in laparoscopic cholecystectomy in patients with total visceral inversion, the gallbladder grasping forceps are inserted through the xiphoid trocar, and the adhesions around the gallbladder are separated with an electric hook to further expose the gallbladder triangle.
Effect evaluation: These cases show that gallbladder grasping forceps play an important role in surgery, can effectively expose the gallbladder, reduce operation time and improve surgical safety.
Mouse-type inverted tooth grasping forceps:
Application case: In endoscopic retrograde pancreaticobiliary angiography, the mouse-toothed forceps were used to repeatedly grasp the residual end of the nasopancreatic duct outside the duodenal papilla, but the residual end was too short to be clamped successfully. This shows that the mouse-type inverted tooth grasping forceps have certain advantages in handling small or broken ducts.
Effect evaluation: Although there may be limitations in some cases, the mouse-type inverted tooth grasping forceps is still a useful tool when dealing with complex anatomical structures, especially when delicate operations are required.
The gallbladder grasping forceps are mainly used to expose the gallbladder in gallbladder surgery and have significant clinical effects, while the mouse-type inverted tooth grasping forceps show their unique advantages when dealing with small or broken tubes.
The precise control technology of duckbill grasping forceps in minimally invasive laparoscopic surgery is mainly achieved through the following aspects:
Master-slave teleoperation system: The laparoscopic surgical robot adopts the "master-slave teleoperation" principle. The doctor controls the main controller on the console and controls the slave hand on the bedside mechanical arm through sensors and computer systems to achieve precise control of surgical instruments. This method can reduce the doctor's fatigue during surgery and improve the accuracy and safety of surgery.
High-performance industrial computer platform: The hardware structure built on high-performance industrial computers uses PCI bus communication, and the functions are expandable, ensuring the stability and response speed of the system. This enables the surgical robot to perform complex surgical movements quickly and accurately.
3D HD imaging system: The surgical system is equipped with a 3D HD imaging system, which can display the situation in the abdominal cavity in real time, allowing doctors to observe the surgical area more clearly and perform more precise operations. This high-resolution image transmission technology is one of the key factors in achieving precise control.
Motion control technology: The robotic system uses the most advanced motion control technology, and even the slowest movements can be comparable to the hands of a skilled surgeon. This technology ensures the smooth and precise movement of surgical instruments in minimally invasive surgery.
Digital camera technology: Using cold light sources to provide illumination, the laparoscope lens is inserted into the abdominal cavity, and the captured images are transmitted to the post-stage signal processing system through optical fibers using digital camera technology, and displayed on the display screen in real time. This technology enables doctors to monitor the surgical area in real time, further improving the accuracy of the operation.
The precise control technology of duckbill grasping forceps in minimally invasive laparoscopic surgery is achieved through the combined action of a variety of high-tech means such as master-slave remote control system, high-performance industrial computer platform, 3D HD imaging system, advanced motion control technology and digital camera technology.
The integrated functions of bipolar electrodes (separation forceps, grasping forceps) in laparoscopic surgery and their impact on surgical results are mainly reflected in the following aspects:
Multifunctional integration: Bipolar electrodes usually have multiple functions such as grasping, pulling, separation and electrocoagulation hemostasis, which reduces the replacement of intraoperative instruments during the operation, thereby improving the efficiency of the operation. For example, in the operation of ovarian cysts, the use of bipolar electrocoagulation hemostasis can stop bleeding while peeling the tissue, greatly protecting the normal function of the ovary.
Safety and ease of operation: The design of bipolar electrodes usually adopts a positive and negative bipolar design. The current only forms a loop at the electrode head and does not flow through the outer sheath, working handle and other instruments that contact the tissue and the human body, avoiding human damage caused by current stimulation. In addition, the handle is easy to open and close, which can reduce the hand strain of the surgeon.
Efficient coagulation and precise control: Bipolar electrocoagulation surgical forceps use high-frequency current for coagulation, which can quickly coagulate tissue, reduce bleeding, and improve surgical efficiency. The surgical forceps have an adjustable current output function, and the doctor can adjust the current intensity as needed to achieve the best surgical effect.
Operation time and success rate: Studies on laparoscopic appendectomy (LA) using bipolar electrocoagulation forceps have shown that the average operation time is 32 minutes, and most patients can successfully complete laparoscopic surgery, and only in very few cases need to be converted to open surgery. This shows that bipolar electrocoagulation forceps have high safety and reliability in laparoscopic surgery.
Issues of disposable use and disinfection: The disposable use of bipolar electrodes can avoid performance degradation caused by repeated sterilization and eliminate the risk of cross infection. This is of great significance for improving the hygiene standards of the surgical environment and reducing the rate of hospital infection.
The integrated function of bipolar electrodes in laparoscopic surgery not only improves surgical efficiency and safety, but also significantly improves surgical results through its versatility and precise control capabilities.
