In laparoscopic surgery, there are many different types of scissors used, which are mainly classified according to their functions and shapes. Here are some common types of laparoscopic surgical scissors:
Scissor-type surgical scissors: This type of scissors is mainly used to cut tissues and blood vessels.
Cutting surgical scissors: This type of scissors is specifically used for cutting operations.
Suturing surgical scissors: This type of scissors is used for cutting and fixing during suturing.
Curved scissors: Also known as Metzenbaum-style scissors, it is a very popular design and is often used in laparoscopic surgery.
Hook scissors: This type of scissors has a hook function for easy operation.
Mini scissors: Small in size, it is convenient for operation in narrow spaces.
Straight-tip scissors: This type of scissors has a straight tip and is suitable for delicate cutting operations.
Long curved scissors: Often used for sharp separation, especially in tissues with no or few blood vessels.
Electric connector scissors: Some scissors are equipped with electric connectors, which can use monopolar or bipolar electrocoagulation while cutting.
These scissors play an important role in laparoscopic surgery, helping doctors complete complex surgical operations such as cutting and suturing. Each type of scissors has its specific design and function, and doctors need to choose the right type of scissors according to specific surgical needs.
Scissor-type instruments used in laparoscopic surgery can be classified according to their structural characteristics and uses. According to the "Medical Device Classification Catalog" published by the State Food and Drug Administration, surgical scissors can be divided into tissue scissors, instrument scissors and endoscopic scissors according to their uses.
Specific to scissors used in laparoscopic surgery, there are mainly the following types:
Straight scissors: This type of scissors is usually a double-action straight-head scissors with a larger size, suitable for situations where a large range of cutting is required. For example, a straight scissors with a size of 5*330mm can be customized to a length of 420mm and 450mm.
Non-destructive grasping forceps with scissor function: This device not only has the function of grasping diseased tissue, but also can shear diseased tissue, solving the problem that traditional grasping forceps can only grasp but not shear.
High-frequency electric knife: Although it is not a scissor in the traditional sense, high-frequency electric knife is also commonly used to cut tissue in laparoscopic surgery and has a wide range of applications.
The application scenarios of these scissors in laparoscopic surgery include but are not limited to the following aspects:
Cutting and separating tissues: During laparoscopic surgery, doctors need to frequently cut and separate diseased tissues, and these scissors play a key role in this process.
Handling adhesive tissues: For those tissues with strong adhesion, traditional grasping forceps may not be able to handle them effectively, while non-destructive grasping forceps with scissor functions can achieve better results.
Delicate operation: In some complex operations, such as surgery on organs such as the liver, gallbladder and pancreas, delicate scissors are required for tiny cuts and operations to avoid damaging surrounding healthy tissues.
The specific methods and advantages of using Metzenbaum curved scissors in laparoscopic surgery are as follows:
Specific usage methods
Correct grip: Metzenbaum curved scissors should be operated with a relaxed grip for smooth and precise movements.
Blunt dissection: The scissors are usually used for blunt dissection, that is, when cutting delicate tissues, the blunt end helps to reduce trauma.
Long handle design: Metzenbaum scissors have a longer handle-to-blade distance, which allows the operator to better control the scissors, especially when operating in deep tissues.
Advantages
High cutting efficiency: The curved tip design conforms to the physiological structure, making the cutting efficiency high.
Multiple length options: A variety of length options are available, with the most recommended length being 7 inches, which helps to adapt to different surgical needs.
Tungsten carbide blades: Tungsten carbide blades achieve 6 times the cutting performance and improve surgical efficiency.
Strong operability: The curved design does not affect the line of sight, making it easier for the operator to see the cutting area, especially in laparoscopic surgery, where the field of view is limited.
Suitable for fragile tissues: Due to their blunt design, Metzenbaum scissors are very suitable for cutting fragile tissues such as the liver, gallbladder, etc.
The hook function of the hook scissors in laparoscopic surgery is mainly achieved through a specific design, which allows for more precise and safe operation during surgery. We can see that the application of the hook device in laparoscopic surgery is mainly reflected in its auxiliary role in suturing the trocar holes.
The hook device is designed to be used at the end of laparoscopic surgery to avoid postoperative hernias caused by large abdominal wall punctures. This device achieves peritonealization by completely suturing the peritoneal layer, thereby improving the safety and effectiveness of the operation. This illustrates the important role of the hook device in maintaining the stability of the surgical field, especially when delicate operations are required to avoid complications.
In addition, although the second piece of evidence does not directly mention hook scissors, it describes a high-frequency dual-output closed cutting blade that is simple and easy to use and can achieve precise cutting and suturing operations. This shows that the use of scissors or other instruments with hook functions in laparoscopic surgery can greatly improve the efficiency and safety of the operation.
Examples of the application of hook scissors in laparoscopic surgery include, but are not limited to: using a hook device to suture the trocar holes during laparoscopic surgery to prevent postoperative hernias. This application demonstrates the important value of the hook device in improving surgical quality and reducing complications.
The hook function of the hook scissors in laparoscopic surgery helps doctors complete surgical operations more accurately and safely by providing an effective surgical auxiliary tool.
When operating mini scissors in a confined space, you need to pay special attention to the following tips and safety precautions:
Choose the right scissors: Make sure to use scissors suitable for the specific task.
Hold the scissors correctly: Use the thumb of your right hand to put it into the handle on one side of the scissors, and use the index finger and the other three fingers to put it into the handle on the other side of the scissors at the same time, with the tip of the scissors facing forward, the scissors stand up, and start cutting from the body to the front. This ensures better control and precision when operating in a confined space.
Keep a safe distance: When using scissors, your hand should be 1-2 cm away from the blade of the scissors to avoid accidentally hurting yourself or others.
Pre-plan the cutting path: Before starting the operation, you should plan the cutting line or path in advance to avoid temporary changes in direction during use to reduce the risk of misoperation.
Avoid using damaged or blunt scissors: Damaged or blunt scissors are prone to slipping or twisting, increasing the difficulty of operation and safety risks. Therefore, the condition of the scissors should be checked regularly and replaced with new ones in time.
Educate children on the correct use of scissors: If children are among those operating scissors in a confined space, they should be taught the correct way to hold and use the scissors to ensure that they do not injure themselves or others.
The advantages of electric connector scissors in laparoscopic surgery are mainly reflected in their ability to provide more precise operation and reduce trauma. Laparoscopic surgery itself is a minimally invasive surgery, which has the advantages of smaller incisions, more precise operation, and less bleeding compared to traditional surgery. As a tool specially designed for electrosurgery, electric connector scissors have a small diameter (2.36 mm and 4 mm) and are suitable for most electrosurgical pens, which means that it can be operated in very narrow spaces, thereby further improving the accuracy of the surgery and reducing damage to surrounding tissues.
However, electric connector scissors also have certain limitations in laparoscopic surgery. First, because it is an electrosurgical tool, it needs to be connected to a power source to work. This may increase the dependence of the device during the operation, and for medical institutions that are not equipped with the corresponding power supply or electrosurgical system, the use of electric connector scissors may bring certain inconveniences. Secondly, although electric splice scissors can provide precise cutting, this high-precision operation also requires doctors to have a high level of skills to ensure the safety and effectiveness of the operation. In addition, the use of electric splice scissors may increase the cost of the operation, because such professional tools are usually expensive and may require specialized training and maintenance.
