The differences in the use of laparoscopic surgical instruments in different surgeries are mainly reflected in the following aspects:

Surgery type and instrument selection:

 

Colorectal cancer surgery: In colorectal cancer surgery, monopolar electric energy instruments are widely used to cut and coagulate tissues. In addition, colorectal cancer surgery also includes various methods such as hand-assisted laparoscopic surgery, laparoscopic-assisted surgery and complete laparoscopic surgery.

Cholecystectomy: Commonly used instruments in cholecystectomy include disposable fine-toothed grasping forceps, corrugated grasping forceps, blunt-head grasping forceps, etc. These instruments can meet the needs of various surgical scenarios.

Appendectomy: In appendectomy, transumbilical single-port laparoscopy can be used to assist intra-abdominal and extra-abdominal methods, and conventional laparoscopic instruments are also used in such surgeries.

Instrument size and design:

Trocar: According to different surgical needs, Trocar has several sizes such as 5mm, 10mm, and 12mm. The inner core of the puncture cone is mainly cone-shaped, which can cause less damage to various layers of tissue.

Handle design: The handle design of laparoscopic instruments is crucial to surgical performance and surgeon ergonomics. Handles of different sizes affect the time and efficiency of surgical execution.

Application of specific instruments:

 

Electric hook: Electric hook is used for cutting and suturing in laparoscopic surgery, and has the characteristics of high-frequency current generating high heat energy.

Grasping forceps: Laparoscopic surgical grasping forceps is a common passive surgical instrument with fine operation and flexible grasping ability. Different types of grasping forceps are selected according to different surgical needs.

Use of disposable instruments:

 

Disposable high-frequency surgical instruments: Such as disposable single-action fine-tooth grasping forceps, double-action fine-tooth grasping forceps, corrugated grasping forceps, etc. These disposable instruments can meet the needs of various surgical scenarios and reduce the risk of cross-infection.
In summary, the differences in the use of laparoscopic surgical instruments in different surgeries are mainly reflected in the type of surgery, instrument selection, size and design, and the application of specific instruments. These differences ensure the safety and effectiveness of the operation and can adapt to different clinical needs.

 

 

What are the specific applications and effects of monopolar electric energy instruments in colorectal cancer surgery?

The application of monopolar electric energy devices in colorectal cancer surgery is mainly reflected in its ability to provide precise cutting and coagulation of tissue. The application of monopolar electric scissors in da Vinci robot-assisted anterior resection of rectal cancer shows that it has the advantage of shorter operation time. This shows that monopolar electric energy devices have a certain effect in improving surgical efficiency.

The working principle of monopolar electric knife is to cut and coagulate tissue through a complete circuit, which consists of a high-frequency generator, a patient plate, a connecting wire and an electrode. The current passes through the patient through the effective wire and the electrode, and then returns to the generator of the high-frequency electric knife through the patient plate and its wire. This design enables monopolar electric energy devices to achieve fast and effective tissue processing while maintaining surgical precision.

In addition, from monopolar or bipolar electric energy devices to ultrasonic energy devices, and then to integrated devices, the continuous research and development and innovation of related equipment have not only promoted the development of laparoscopic colorectal cancer surgery towards precise resection, but also fed back colorectal cancer surgical techniques including open surgery. This shows that the development of monopolar electric energy devices and their subsequent technologies is of great significance to improving the overall effect of colorectal cancer surgery.

The specific application of monopolar electrical energy devices in colorectal cancer surgery is to provide precise cutting and coagulation of tissue, and its effect is reflected in the shortening of surgical time and the improvement of surgical efficiency.

 

 

What are the results of comparative studies on different grasping forceps (disposable fine-tooth grasping forceps, corrugated grasping forceps, and blunt-tipped grasping forceps) in cholecystectomy?

There is currently no direct evidence comparing the effects of disposable fine-tooth grasping forceps, corrugated grasping forceps, and blunt-tipped grasping forceps in cholecystectomy. However, the characteristics and possible applications of these grasping forceps can be inferred from the relevant literature.

Disposable fine-tooth grasping forceps: This grasping forceps is usually used in surgeries that require delicate operations. Its fine-tooth design helps to better grasp and pull the gallbladder, reducing the risk of slippage and injury during surgery. Although there are no direct research results, it can be inferred that this grasping forceps may show better results in surgeries that require precise control of the position and direction of the gallbladder.

Corrugated grasping forceps: The design of the corrugated grasping forceps is intended to provide a larger grasping area, thereby increasing stability and pulling force during surgery. This type of grasping forceps is suitable for surgical scenarios that require greater traction, such as cholecystitis or gallstones with larger gallbladder masses.

Blunt grasping forceps: The design of the blunt grasping forceps avoids direct stimulation of surrounding tissues, which helps reduce postoperative pain and inflammatory reactions. This type of grasping forceps is suitable for surgeries that require high postoperative recovery, especially when the patient is sensitive to pain or has other complications.

Although there are no direct comparative research results, by analyzing the design characteristics and applicable scenarios of different types of grasping forceps, their respective advantages and applicability in cholecystectomy can be inferred.

 

 

What are the advantages and disadvantages of transumbilical single-port laparoscopic-assisted intraabdominal method and extraabdominal method in appendectomy?

The advantages and disadvantages of transumbilical single-port laparoscopic-assisted intraabdominal method and extraabdominal method in appendectomy are as follows:

Transumbilical single-port laparoscopic-assisted intraabdominal method

Advantages:

Less trauma and faster recovery: Transumbilical single-port laparoscopic surgery is performed through a small incision, which is less traumatic and has a shorter postoperative recovery time than traditional open surgery.
Wide field of vision: The entire abdominal cavity can be explored during the operation to detect and treat other possible lesions.
Less pain and short hospital stay: Due to the small trauma, the postoperative pain is less and the hospital stay is relatively short.
Fewer postoperative complications: The surgical risk is low and the incidence of postoperative complications is low.
Good cosmetic effect: The incision is small and heals quickly, which is better for people who pay attention to appearance.

Disadvantages:

High cost: Due to the use of advanced equipment and technology, the cost of surgery is relatively high.
Difficult operation: Although the technology is mature, it is difficult for beginners to operate and requires certain training and experience.

 

Extraperitoneal method (traditional laparotomy)

Advantages:

Simple technology: Traditional laparotomy is mature and simple to operate, suitable for the treatment of acute appendicitis in various situations.
Low cost: Since advanced laparoscopic equipment is not required, the cost of surgery is low.

Disadvantages:

Large trauma and slow recovery: Traditional laparotomy requires a larger incision and a longer postoperative recovery time.
Strong pain and long hospital stay: Due to the large trauma, the postoperative pain is strong and the hospital stay is also longer.
High risk of incision infection: The incision infection rate of traditional laparotomy is high, especially in cases of severe appendicitis or abdominal wall obesity.
Poor cosmetic effect: The incision is large and the postoperative scar is obvious, which is not conducive to beauty.
The transumbilical single-port laparoscopic assisted intraperitoneal method has obvious advantages in terms of small trauma, fast recovery, and wide field of view, while the extraperitoneal method has its unique advantages in terms of simple technology and low cost.

The application of electric hooks in laparoscopic surgery and its impact on surgical safety and efficiency.
The application of electric hooks in laparoscopic surgery has significant advantages and potential risks, and has an important impact on the safety and efficiency of surgery.

 

 

Widely used

The electric hook is widely used in laparoscopic surgery, especially in colorectal surgery. It is mainly used for intraoperative tissue separation, incision and electrocoagulation hemostasis. For example, in laparoscopic cholecystectomy, the electric hook is often used in conjunction with bipolar electrocoagulation forceps. The bipolar electrocoagulation forceps are first used to coagulate the gallbladder artery, and then the electric hook is cut off to ensure that the bleeding point in the surgical field is effectively controlled.

 

 

Improve surgical safety

The electric hook generates high heat energy through high-frequency current, which can accurately cut and coagulate tissue, thereby reducing the incidence of autonomic nerve-related complications. In addition, the high operational stability of the electric hook helps to reduce intraoperative bleeding and improve the safety of the operation.

 

 

Impact on surgical efficiency

Although the electric hook has many advantages in surgery, it also has some disadvantages. When cutting and peeling the mass, the existing electric hook cannot accurately judge the size of the mass, which is easy to cause misjudgment, thereby increasing the operation time and reducing the efficiency of the operation. However, the design of the new electric hook is to improve accuracy, reduce the pressure on doctors and patients, and thus improve the efficiency of the operation.

 

 

Safety precautions

When using the electric hook for laparoscopic surgery, it is necessary to follow the correct operating procedures and pay attention to safety. For example, in gynecological tumor surgery, the use of monopolar electric knives requires special attention to avoid thermal damage.

Conclusion
The application of the electric hook in laparoscopic surgery significantly improves the safety and efficiency of the operation, but it is also necessary to pay attention to its potential risks and operating skills to ensure the success of the operation and the safety of the patient.

 

 

What is the mechanism by which disposable high-frequency surgical instruments reduce the risk of cross infection?

The mechanism by which disposable high-frequency surgical instruments reduce the risk of cross-infection is mainly reflected in the following aspects:

 

Disposable use: Disposable high-frequency surgical instruments are designed for single surgery, ensuring that each patient uses a brand new instrument, thereby avoiding the spread of pathogens and the risk of cross-infection. This design allows doctors to use brand new electrodes and other related equipment in each operation to ensure the hygiene and safety of the operation.

 

Improving surgical efficiency: Since each package is disposable, doctors can complete surgical steps faster, reducing surgical time and patient discomfort. This not only improves surgical efficiency, but also further reduces the risk of cross-infection because it reduces the possibility of multiple people sharing the same set of instruments.

 

Technical advantages: Modern disposable high-frequency surgical instruments use advanced technologies such as STS intelligent tissue sensing technology and EVS enhanced coagulation technology, which can achieve precise energy output and reduce the risk of accidental burns. The thinner and narrower blade design makes the wandering gap more comfortable, and the rounded design is not afraid of vascular scratches. The application of these technologies not only improves the safety and effectiveness of surgery, but also further reduces the risk of cross-infection.

 

Strict quality control: Disposable high-frequency surgical instruments will undergo strict quality control and testing during the production process to ensure their electrical safety and stability. For example, the high-frequency leakage current and other detection indicators of high-frequency surgical equipment are measured by the QA-ES high-frequency electric knife tester to ensure the safety of the equipment.
