How to use laparoscopes correctly for surgery to ensure safety and effectiveness?

To properly use laparoscopy for surgery to ensure safety and effectiveness, it is necessary to comprehensively consider multiple aspects of preparation and operation:

Preoperative preparation:

Systemic examination: including electrocardiogram, chest X-ray, liver and kidney function test, blood routine, biochemical test and infectious disease test, etc.
Skin preparation: routine skin preparation, clean skin, pay special attention to the cleanliness of the navel, because the navel needs to be punctured.
Intestinal preparation: For larger surgeries, such as malignant tumors, uterine adenocarcinoma or ovarian cancer, intestinal preparation is required, and drugs that kill intestinal bacteria are used as an auxiliary. Generally, adults should fast for 12 hours before surgery.
Psychological preparation: Understand the patient's psychological condition, assess their emotional state such as anxiety, fear and depression, as well as their expectations and concerns about surgery and postoperative recovery.
Intraoperative precautions:

Pneumoperitoneum management: Especially the effect of CO2 pneumoperitoneum on the body's respiratory, circulatory system and systemic hemodynamics during laparoscopic surgery, which needs to be closely monitored and adjusted in time.
Simplify the surgical process: For patients with reduced tolerance, the operation time should be shortened as much as possible and the surgical process should be simplified to reduce the impact of CO2 pneumoperitoneum on the body.
Postoperative management:

Complication prevention and treatment: Risks and complications that may occur during surgery, such as emphysema, require pre-made emergency plans and timely identification and treatment during surgery.

What are the specific application scenarios of electrocoagulation hooks and bipolar electrocoagulation in laparoscopic surgery?

In laparoscopic surgery, electrocoagulation hooks and bipolar electrocoagulation forceps each have specific application scenarios.

Application scenarios of electrocoagulation hooks
Treatment of intertissue adhesions: The electrocoagulation hook pushes away the adhesions between tissues through its blunt force, creating a free plane, thereby providing better operating space for surgery.
High-frequency electrocoagulation hemostasis and cutting: The electrocoagulation hook is used for high-frequency electrocoagulation hemostasis and cutting in most laparoscopic surgeries. It melts or destroys tissues through electrical energy to achieve the purpose of hemostasis, cutting or removing tissues.
Strong compatibility: The electrocoagulation hook does not require special pneumoperitoneum and laparoscopic equipment, is compatible with operating room conditions and equipment, and is suitable for use with laparoscopic systems, thoracic systems, gynecological systems, urological systems, endoscopes, etc.
Application scenarios of bipolar coagulation forceps
Cholecystectomy: In laparoscopic cholecystectomy, bipolar coagulation forceps are first used to coagulate the gallbladder artery, then cut with a coagulation hook, and the bleeding point in the surgical field is electrocoagulated and hemostatic with bipolar coagulation forceps.
Appendectomy: Bipolar coagulation forceps are used to treat the appendix mesentery in appendectomy, so that the main operation hole is changed from 12mm to 5mm, thereby reducing the size of the incision.
Fine coagulation surgery: Bipolar coagulation forceps are suitable for fine coagulation surgeries such as plastic surgery, ENT, ophthalmology, hand and foot, thyroid, breast head and neck surgery, pediatrics, and urology.

How to choose the appropriate type and number of forceps in laparoscopic surgery?

In laparoscopic surgery, choosing the appropriate type and number of forceps requires comprehensive consideration of the surgical site, surgical requirements, and the specific conditions of the patient. The following are detailed steps and suggestions:

Confirm the surgical site and surgical requirements:

Before surgery, the doctor should clarify the surgical site and the type of surgical forceps required based on the patient's condition and surgical needs. For example, if the surgery involves grasping or cutting larger tissues, large grasping forceps may be required.
Choose the right type of forceps:

Choose the right type of forceps according to the surgical site and needs. Common types of forceps include dissecting forceps, grasping forceps, abdominal wall suture forceps, gold finger retractors, etc.
Dissecting forceps can be used to separate tissues, grasping forceps are used to clamp and move tissues, abdominal wall suture forceps are used to suture the abdominal wall, and gold finger retractors are used to pull organs.
Consider the specifications and length of the forceps:

The specifications and length of the forceps will affect its operability and scope of application. Common forceps lengths are 330mm, 345mm and 450mm. Depending on the surgical site, you can choose different shapes of forceps such as straight dissecting forceps, curved dissecting forceps or right-angle dissecting forceps.
Choose multifunctional or special forceps:

Depending on the complexity and needs of the surgery, you can choose multifunctional forceps or special forceps. For example, fan-shaped forceps (hollow hammers) have high hardness and size suitability, and are suitable for a variety of surgical scenarios.
Consider the material and durability of the forceps:

Forceps made of high-quality stainless steel have good corrosion resistance and structural sturdiness, are light in weight and easy to operate.
Choice of quantity:

Choose the appropriate number of forceps according to the scale and complexity of the operation. Generally speaking, each surgeon should prepare at least two to three different types of forceps to meet different surgical needs.

How to correctly install and use the Veress needle in laparoscopic surgery to improve operational efficiency?

In laparoscopic surgery, the correct installation and use of the Veress needle is crucial to improving operational efficiency. The following are detailed steps and precautions:

Choose the corresponding model of Veress needle according to the patient's surgical needs, and confirm whether the instruments and accessories used in conjunction are matched.

Open the sterile package, take out the Veress needle, and ensure that the value of its outer surface roughness parameter Ra is not greater than 0.8μm to prevent infection.

Make a 1cm small incision in a longitudinal or arc shape at the puncture point to facilitate puncture.

Puncture process:

Ensure that the Veress needle is in the correct position to avoid injury to internal organs.
There are generally two breakthroughs before and after penetrating the white line. Retract your hand in time, and then pull the Veress needle up and down to feel whether there is any obstruction. The twitching amplitude is about 1cm. If it is too deep, it is easy to puncture the intestinal tube below or puncture the omental blood vessels or puncture the mesentery, causing mesentery inflation and affecting the field of vision.
During the puncture process, control the flow and pressure of the gas to prevent excessive expansion of the abdominal cavity.
Connection and inspection of the pneumoperitoneum needle:

The coordination with the inner needle, valve core, and valve body should be good, without obstruction. The valve core should be easy and flexible to open and close; the connection or welding part of the pneumoperitoneum needle should be firm, without looseness or cold welding; the valve body to the inner needle tube should be unobstructed and without obstruction.
Monitoring after the establishment of pneumoperitoneum:

Intraoperative detection of blood oxygen saturation and arterial blood gas analysis, timely observation of the patient's vital signs and symptoms.
When the pneumoperitoneum pressure reaches 15mmHg, pull out the pneumoperitoneum needle and insert a trocar at the original puncture point.
Precautions:

Paying attention to every detail in the pneumoperitoneum needle puncture is of great benefit to improving surgical safety.
During a closed abdominal approach, pulling the umbilicus caudally below the sacrum and great vessels can facilitate the insertion of the Veress needle and maximize the success rate of insertion and avoid injury.
